(Outline of one embodiment of the present invention)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a slot machine 1 as a gaming machine according to an embodiment of the present invention includes a normal game started by a bet on the condition of consumption of a credit value (game value), and a predetermined game in the normal game. A free game that is triggered and started when the condition is satisfied is made executable. The credit value can be received by a BET button that functions as a bet receiving mechanism.

  Further, the slot machine 1 has a progressive payout as a prize. A progressive payout is a special payout that is different from a normal payout in a broad sense. In this embodiment, the progressive payout is a payout in which a part of the bet number (bet amount) betted in the slot machine is accumulated for each normal game, and is awarded to the player when a predetermined condition is satisfied.

  When the slot machine 1 accepts a credit value bet by the bet acceptance mechanism (S1), it starts a normal game (S2). In this normal game, a game result is determined by lottery, and a prize corresponding to the game result is awarded. If the award to be given is the right to transfer to the free game (free game trigger) (S3: YES), the slot machine 1 shifts to the free game (S4). Further, the slot machine 1 determines whether or not to give a progressive payout by lottery with reference to a progressive winning / non-winning table (corresponding to a lottery table) (S5: progressive lottery). This lottery table increases the probability of winning when a progressive payout is awarded as a prize (progressive payout wins) as the number of bets placed in the base game that triggered the transition to the free game increases. It is a table which has a plurality of associated winning probabilities.

  When the progressive payout is won in the process of S5 (S6: YES), the slot machine 1 gives a progressive payout when the free game is over (S7), and returns to the process of S1. On the other hand, if the progressive payout is not won in the process of S5 (S6: NO), a fixed payout is awarded when the free game is over (S8), and the process returns to S1.

(Definitions, etc.)
The slot machine is a kind of gaming machine. In the present embodiment, the slot machine 1 will be described as an example of a gaming machine, but the present invention is not limited to this, and any device that can independently execute some normal game may be used.

  The base game and the free game in the present embodiment are executed by the slot machine 1. The normal game and the free game are slot games in which a plurality of symbols (see FIG. 29, etc.) are rearranged. Note that the rearrangement of symbols in the slot game is performed by a mechanical reel device.

  The symbol means a generic name of “WILD”, “RED7”, “GREEN7”, “3BAR”, “2BAR”, “1BAR”, “BONUS”, and “BLANK”. Of these symbols, “BONUS” is a symbol serving as a trigger for starting execution of the free game. “BLANK” is a symbol having no pattern unlike other symbols.

  The normal game is a game in which symbols are rearranged on the display window by a mechanical reel device on the condition that a credit value is bet, and a prize is awarded according to the rearranged symbols. In other words, the normal game is a game that is started on the premise of a credit value bet. On the other hand, a free game is a game that can be executed with a smaller credit value bet than a normal game. “Can be executed with less credit value bet” includes the case where the bet is “0”. In the present embodiment, the “free game” is a game that is executed without a bet of a credit value. In other words, the “free game” is a game that is started without assuming the consumption of credit values.

  In addition, the free game in the present embodiment is executed when a predetermined condition is satisfied in the normal game. The free game is a game in a game state that is more advantageous than the normal game, and other free games may be adopted together as long as the game state is advantageous for the player, that is, a game state that is more advantageous than the normal game. For example, a free game has various states such as a state in which more game values can be acquired than a normal game, a state in which game values can be acquired with a higher probability than a normal game, and a state in which the number of game values consumed is lower than in a normal game. May be realized alone or in combination.

  The game value (credit value) is electronic valuable information such as electronic money. Note that the game value in the present invention is not particularly limited, and may be a game medium such as a coin, a medal, a token, or a ticket. The ticket is not particularly limited, and may be, for example, a ticket with a barcode attached with a barcode in which data such as a credit value is encoded. Further, the “game value” may be a game point that does not include valuable information.

  Rearrangement means a state in which symbols are arranged again after the arrangement of symbols is canceled. Arrangement means that a symbol can be visually confirmed with respect to an external player. Specifically, in the rearrangement, the symbols on the reel are displayed in a scrolling manner (scroll display) as the reel rotates, and then the reel rotation stops and the symbol fluctuation display is stopped. It is in a state of stopping in the display window.

(Explanation of functional flow diagram)
With reference to FIG. 2, the basic functions of the slot machine according to the embodiment of the present invention will be described. FIG. 2 shows a functional flow of the slot machine according to the embodiment of the present invention.

<Bet start check>
First, the slot machine checks whether or not the BET button has been pressed by the player, and subsequently checks whether or not the spin button has been pressed by the player. Further, the slot machine cumulatively adds a part of the bet number betted to the progressive payout stored in the storage device for each normal game (unit game).

<Symbol decision>
Next, when the spin button is pressed by the player, the slot machine extracts a random number for symbol determination, and displays (rearranges) the reel when the rotation of the reel is stopped according to each of the plurality of reels. Determine the symbol to be used.

(Reel control)
Next, the slot machine performs a control to start the rotation of each reel and stop the rotation of each reel so that the determined symbol is displayed to the player.

<Winning determination>
Next, when the rotation of each reel is stopped, the slot machine determines whether or not the combination of symbols displayed to the player is related to winning.

<Awarding>
Next, when the combination of symbols displayed on the player is related to winning, the slot machine gives an award according to the type of combination of symbols to the player. For example, when a symbol combination related to the grant of a credit is displayed, the slot machine grants the player a number of credits corresponding to the symbol combination.

  Further, the slot machine starts the free game when the symbol combination related to the free game trigger is displayed. In the embodiment of the present invention, as a free game, a game in which the lottery related to the determination of the stop scheduled symbol is performed (hereinafter also referred to as a bonus free game) is executed a predetermined number of times without consuming a credit value. The

  In addition, the slot machine executes a progressive lottery that determines whether or not to give a progressive payout when a combination of symbols related to the free game trigger is displayed. When the slot machine determines to give a progressive payout in the progressive lottery, it gives the player a progressive payout amount stored in the storage device. On the other hand, when it is determined in the progressive lottery that a progressive payout is not awarded, a fixed payout that is a fixed payout is awarded.

  The slot machine may be provided with prizes such as a mystery bonus and insurance in addition to the above prizes. In the mystery bonus, a predetermined amount of credit is given by winning a special lottery. In this case, when the spin button is pressed, the slot machine extracts a random value for the mystery bonus and determines by lottery whether or not to establish the mystery bonus trigger.

  Insurance is a function provided for the purpose of relieving the player from a situation where a free game has not been played for a long period of time. When insurance is activated, it is exchanged for a predetermined amount of insurance. When insurance is validated, the slot machine starts counting the number of games. Then, the slot machine gives a credit of an amount set for insurance when the counted number of games reaches a predetermined number without giving a large amount of credit by a free game or the like.

<Determination of production>
The slot machine produces an effect by displaying an image on a display, outputting light from a lamp, and outputting sound from a speaker. The slot machine extracts a random number for production, and determines the content of the production based on the symbol determined by lottery.

(First normal game symbol table)
Next, a first normal game symbol table used when the game state of the slot machine 1 is in the progress-off state will be described with reference to FIG. 8A. As shown in FIG. 8A, the 22 symbols corresponding to the respective code numbers “00” to “21” in each of the reels 101 to 105 are set with a weight (WEIGHT) value corresponding to the normal game. Yes. This weight indicates the magnitude of the probability that the corresponding symbol 501 is rearranged in the middle stage of the display window 150. That is, the probability that the corresponding symbol 501 is rearranged in the middle stage of the display window 150 is a value obtained by dividing the code number weight of the symbol by the sum of the code number weights of all symbols. For example, as shown in FIG. 8A, “BONUS” corresponding to the code number “00” of the first reel 101 is rearranged in the middle of the display window 150 with a probability of 1/67. Further, “3BAR” corresponding to the code number “04” of the second reel 102 is rearranged in the middle of the display window 150 with a probability of 3/68.

  By the way, the slot machine 1 in the present embodiment has a plurality of types of game settings in order to cope with regulations (regulations) that differ depending on the country / region, and one of the plurality of game settings is selected by the audit setting. It is configured to be possible. Specifically, there are seven settings V01 to V07 as game settings, and one of these seven game settings can be selected by the audit setting. The first base game symbol table includes seven types corresponding to the seven types of game settings. FIGS. 8A and 8B show V01 and V02 games among these seven types of game settings. A first base game symbol table corresponding to the setting is shown.

(Second normal game symbol table)
When the game state of the slot machine 1 is the pre-logon state, the second normal game symbol table shown in FIG. 9 is used. Also in the second base game symbol table, the weight values corresponding to the base game are set for the 22 symbols corresponding to the code numbers “00” to “21” in the reels 101 to 105, respectively. ing. In the first normal game symbol table and the second normal game symbol table, at least one of the weight values set for each of the 22 symbols corresponding to the code numbers “00” to “21”. Are different. For this reason, the probability that the 22 symbols on each of the reels 101 to 105 are rearranged in the middle stage of the display window 150 differs depending on whether the game state is the prog-off state or the pro-logon state. There are also seven types of second normal game symbol tables corresponding to seven game settings of V01 to V07. FIG. 9 shows a second normal game symbol table corresponding to the game setting of V02. ing.

(Free game symbol table)
In the free game, when the slot machine 1 is in both the prog-off state and the pre-logon state, the free game symbol table shown in FIG. 10 is used in common. Also in this free game symbol table, the weight values corresponding to the free game are set for each of the 22 symbols corresponding to the respective code numbers “00” to “21” in each of the reels 101 to 105. . Also, in this free game symbol table, seven types are provided corresponding to seven game settings of V01 to V07, and FIG. 10 shows a free game symbol table corresponding to the game setting of V01.

(Dividend table)
Next, the payout table will be described with reference to FIGS. Each of the payout tables shown in FIGS. 11 to 13 defines combinations of symbols (number of symbols) related to winning (WIN) and the number of credits given. The line winning payout table shown in FIG. 11 is a line winning payout table used in common in both the prog-off state and the pre-logon game state, while the first scatter winning payout shown in FIG. The table is a scatter winning payout table used in the prog-off state, and the second scatter winning payout table shown in FIG. 13 is a scatter winning payout table used in the prologon state.

  In the slot machine 1, the scroll of the symbol columns of the reels 101 to 105 is stopped, and the symbol combination displayed on the PAY LINE is a symbol combination defined by the line winning payout table shown in FIG. If it matches, the line winning is established. In accordance with the winning, a prize such as a credit is given to the player. If the symbol combination displayed on the PAY LINE does not match any of the symbol combinations defined by the line winning payout table, the winning is not established (so-called “losing”).

  In the present embodiment, basically, for each type of symbols “RED7”, “GREEN7”, “3BAR”, “2BAR”, and “1BAR”, there are three types of symbols on one PAY LINE. Line winning is achieved when all four, five, or five are rearranged. In addition, when two types of symbols “RED7” and “GREEN7” are rearranged on one PAY LINE, and the number of symbols is 3, 4, or 5, “ANY7” is established, Two or more of the three types of symbols “3BAR”, “2BAR”, and “1BAR” are rearranged on one PAY LINE, and the number of symbols is three, four, or five. In this case, “ANYBAR” is established.

  For the “WILD” symbol, each type of symbol “RED7”, “GREEN7”, “3BAR”, “2BAR”, and “1BAR” is substituted. In the present embodiment, when a line winning is established, if one “WILD” symbol is arranged on the PAY LINE related to the line winning, the number of credits awarded is doubled to two. When the “WILD” symbol is arranged, the number of credits granted is specified to be quadrupled.

  In addition, the line winning payout table shown in FIG. 11 is a table that defines the number of credits to be awarded when a base game is executed with one bet per payline. When a normal game is executed with a bet number other than one bet per one PAY LINE, a multiplication value obtained by multiplying the credits given number shown in FIG. 11 is given as a multiple of the bet number per one PAY LINE. It is determined as the number of credits granted.

  Therefore, for example, when a normal game is executed with 5 bets per one PAY LINE and three “RED7” are arranged on one PAY LINE, it is determined that the winning is 250 = (50 × 5) Credit is granted. In addition, when a base game is executed with 10 bets per pay line, if 5 “3BARs” are placed on one pay line, it is determined that the winning is won and 2000 (= 200 × 10) credits are given. Is granted.

  Further, in the present embodiment, when the game state of the slot machine 1 is the progress-off state, if five or more “BONUS” symbols are rearranged in the display window 150, a BONUS AWARD scatter prize is established. The scatter winning may be when the “BONUS” symbol displayed on the first reel 101 to the fifth reel 105 is rearranged in any one of the upper, middle, and lower stages of the display window (PAY LINE does not matter).

  The number of credits to be awarded at the time of scatter winning is the total number of bets (= number of PAY LINEs × one PAY LINE) bet in the base game with respect to the number of credits given in the first scatter winning payout table shown in FIG. This is a multiplication value obtained by multiplying (the number of bets per game). Therefore, when the total number of bets in the base game is 25 bets, if 6 “BONUS” symbols are rearranged, 50 (= 2 × 25) credits are awarded, and the “BONUS” symbol is 10 When the pieces are rearranged, 2500 (= 100 × 25) credits are given.

  Further, as shown in the second scatter winning dividend table of FIG. 13, when the game state of the slot machine 1 is the pre-logon state, even if five or more “BONUS” symbols are rearranged in the display window 150, the credit Is not given to the player.

  As mentioned earlier, in the present embodiment, the “BONUS” symbol is a symbol that triggers a free game. When five or more of these “BONUS” symbols are rearranged in the display window 150, “Free Game Trigger” is determined as a winning combination, and a free game is entered.

(Free game)
Next, a free game will be described with reference to FIG. As shown in FIG. 14, the free game includes a prize selection and a plurality of bonus free games. In each bonus free game, when one or more “BONUS” symbols are displayed on the display window 150, a payout according to the number of “BONUS” symbols displayed on the display window 150 is specially awarded. . The prize selection is a process of determining a reference payout value for one symbol “BONUS”.

  More specifically, in prize selection, a payout lottery process (to be described later) for determining a payout value is executed a predetermined number of times, and the total payout value determined in each payout lottery process is used as a reference payout for one symbol of the “BONUS”. Value.

  The number of payout lottery processes in the prize selection is determined with reference to the lottery number table shown in FIG. In the lottery table, the number of lotteries for executing the payout lottery process is associated with the number of “BONUS” symbols displayed in the display window 150 in the base game or the free game. For example, when seven “BONUS” symbols are rearranged in the display window 150 in the base game, the lottery number table shown in FIG. 15 is referred to and the number of payout lottery processes is determined to be three.

  In each payout lottery process, the payout value is determined with reference to the prize selection table shown in FIG. In this prize selection table, a predetermined payout value and a weight (winning probability) are associated with the area numbers of the 12 payout areas 202 arranged in the roulette 201 (see FIG. 34). In the payout lottery process, referring to the prize selection table, a lottery according to the weight is performed to determine the payout value. For example, the region number “No. 0” is won by lottery with a probability of 1/100, and the payout value is determined to be “750”.

  In each free game, the area number (payout area 202) once won by the payout lottery process is configured not to be won again. For example, each time a payout lottery process is performed, a process of changing the weight associated with the determined region number to zero in the prize selection table shown in FIG. 16 is performed. Therefore, in the present embodiment, the maximum value of the reference payout value for one “BONUS” symbol is a value obtained by adding up the payout values associated with each area number. As a modification, each free game may be configured such that the area number once won by the payout lottery process can be won again.

  During the payout lottery process, the roulette 201 is displayed on the upper image display panel 131 as shown in FIG. The roulette 201 has twelve payout areas 202 associated with twelve area numbers “No. 0” to “No. 11”. Then, the twelve payout areas 202 of the roulette 201 are lit and displayed in order of increasing the luminous intensity in order in a clockwise order (increase the luminous intensity), so that the lottery is performed by the roulette. Production to show.

(Special dividend determination process)
When the game state of the slot machine 1 is in the progress-off state, the game returns to the normal game when the free game ends. On the other hand, when the game state of the slot machine 1 is the pre-logon state, as shown in FIG. 14, when the free game ends, any one of the four types of progressive payouts and the three types of fixed payouts having different payout values from each other. A special payout determination process for awarding one payout as a prize is executed. This special payout determination process includes a blog lottery, a blog rank lottery, and a fixed payout rank lottery.

  The progressive rank lottery is a lottery for determining which of the four types of progressive payouts is to be awarded when the free game ends. The fixed payout rank lottery is a lottery for determining which of the three types of fixed payout is to be awarded when the free game is finished. The prog lottery is a lottery for determining which of the prog rank lottery and the fixed payout rank lottery is executed. In other words, the progressive lottery is a process for determining whether a progressive payout is won or not as an award to be awarded when the free game ends. Hereinafter, each lottery will be described in detail.

(Prog lottery)
In the progressive lottery, the progressive winning / non-winning table shown in FIG. 17A is used to determine whether to win a progressive payout as a prize to be awarded when the free game is over or not. The progressive winning / non-winning table sets the weight for each of the winning and non-winning progressive payouts for each bet that can be bet per pay line in the regular game that triggered the transition to the free game. It is a table. This weight indicates the magnitude of the probability that the progressive payout is won and the magnitude of the probability that the prize is not won as a prize to be awarded when the free game is completed in the progressive lottery. In other words, the progressive winning / non-winning table is a table having a probability of winning a progressive payout for each bet that can be bet per one PAY LINE in a normal game that is an opportunity to shift to a free game.

  Note that the value of “Bet Multiplier” shown in the blog winning / non-winning table indicates the number of bets bet per one PAY LINE in a normal game that has triggered the transition to the free game. For example, “1” of “Bet Multiplier” indicates that the number of bets per one PAY LINE in the normal game is 1 bet, and “3” indicates that the number of bets per 1 PAY LINE in the normal game is 3 bets. Show. Thus, for example, when the number of bets per pay line in a normal game is 3 bets, the probability that the progressive payout is won is 16522482/180921300, and the probability that the progressive payout is not won (the fixed payout is won) Is the probability of 16439818/180921300.

  In the present embodiment, as can be seen from the blog winning / non-winning table shown in FIG. 17A, as the bet number (credit value) bet in the base game that triggered the transition to the free game increases, Are set so that the probability that the progressive payout is won is high (the weight when the progressive payout is won is large).

  In this embodiment, there are seven types of program winning / non-winning tables corresponding to the seven game settings of V01 to V07. In FIGS. 17A to 17C, the game settings of V01 to V03 are set. The corresponding program winning / non-winning table is shown. The seven types of progressive winning / non-winning tables contain weights for winning and non-winning progressive payouts that are set for each bet in the base game that triggered the transition to the free game. A plurality of types of program winning / non-winning tables whose values are different from each other are included. For this reason, the probability that the progressive payout is won can be changed by selecting any one of the game settings V01 to V07 by the audit setting.

(Prog rank lottery)
The progressive rank lottery is a lottery for determining any one of four types of progressive jackpots (“GRAND JACKPOT”, “MAJOR JACKPOT”, “MINOR JACKPOT”, and “MINI JACKPOT”). In the present embodiment, the case where there are four types of progressive jackpots will be described. However, the present invention is not particularly limited to this and may be one or more.

  Each of the four types of progressive jackpot payouts is composed of a value obtained by adding a progressive initial payout value and a value obtained by incrementing a predetermined ratio (increment rate) of the number of bets placed for each normal game. Has been. The progressive initial payout value and the increment rate corresponding to each of the four types of progressive jackpots are defined in the progressive payout setting table shown in FIG.

  As shown in FIG. 18, the progressive initial payout value increases in the order of “GRAND JACKPOT”, “MAJOR JACKPOT”, “MINOR JACKPOT”, and “MINI JACKPOT”. The progressive initial payout value is larger than any of the three types of fixed payout values. That is, the four types of progressive payouts have a higher payout value than any of the three types of fixed payouts.

  In addition, there are four types of progressive initial payout values corresponding to the game settings of SC01 to SC04 for each of the four progressive jackpots. When the audit selects one of the four types of game settings of SC01 to SC04, the progressive initial payout value of each of the four progressive payouts can be changed.

  Also, for “GRAND JACKPOT”, a value of 0.10% of the bet number in the normal game, for “MAJOR JACKPOT”, a value of 0.20% of the bet number in the normal game, “MINOR” “JACKPOT” has a value of 0.30% of the bet number in the normal game, and “MINI JACKPOT” has a value of 0.40% of the bet number in the normal game for each normal game. Incremented and accumulated cumulatively. Note that the increment rate may be changeable by setting the audit. For example, the increment rates of “GRAND JACKPOT”, “MAJOR JACKPOT”, “MINOR JACKPOT”, and “MINI JACKPOT” may be set to be the same. Further, as shown in FIG. 18, an upper limit value of a progressive payout is set for each of “GRAND JACKPOT”, “MAJOR JACKPOT”, “MINOR JACKPOT”, and “MINI JACKPOT”.

  In the progressive rank lottery, any one of the four types of progressive jackpots is determined with reference to the progressive payout table shown in FIG. 19A. The progressive payout table is a table in which weights are set for each of the four types of progressive jackpots. This weight indicates the probability of each of the four types of progressive jackpots being determined in the progressive rank lottery. That is, the probability that each progressive jackpot is determined in the progressive rank lottery is a value obtained by dividing the weight of the progressive jackpot by the sum of the weights of all the progressive jackpots. For example, the probability that “MINOR JACKPOT” wins in the program rank lottery is 820/10000.

  In the progressive payout table, the winning probability of each of the four types of progressive jackpots is invariant regardless of the number of bets (credit value) bet on the base game that triggered the transition to the free game. For example, the probability that “MINOR JACKPOT” wins in the program rank lottery is “20” even when the number of bets placed on one PAY LINE is “1” in the base game that triggered the transition to the free game. ”Is 820/10000.

  In the present embodiment, four types of progressive payout tables are provided corresponding to the game settings of SC01 to SC04. Then, one of the four types of progressive payout tables is selected according to the audit setting. 19A to 19D show progressive payout tables corresponding to the game settings of SC01 to SC04, respectively. In the four types of progressive payout tables, at least some of the weight values for the progressive jackpots are different from each other. For this reason, the probability that the progressive jackpot is determined in the progressive rank lottery can be changed by selecting any one of the game settings SC01 to SC04 by the audit setting.

(Fixed dividend rank lottery)
Fixed prize rank lottery is a lottery to determine any one of three fixed payout ( "CREDIT _{_} 1""CREDIT _{_} 2""CREDIT _{_} 3"). In the present embodiment, as shown in fixed payout allocation table of FIG. 20, "CREDIT _{_} 1" to "25", the "CREDIT _{_} 2", "30", the "CREDIT _{_} 3""100" Dividend values are assigned to each.

  In the fixed payout rank lottery, any one of the three types of fixed payouts is determined with reference to the fixed payout table shown in FIG. 21A. The fixed payout table is a table in which weights are set for each of the three types of fixed payouts for each number of bets that can be bet per one PAY LINE in the base game that has triggered the transition to the free game. This weight indicates the probability of each of the three types of fixed payouts being determined in the fixed payout rank lottery.

In this embodiment, as can be seen from the fixed payout table shown in FIG. 21A, a fixed payout having a large payout value increases as the number of bets bet in the normal game that triggered the transition to the free game increases. The probability of winning is set to be high. That is, the higher the credit value betted in the base game that triggered the transition to the free game, the higher the weight of the fixed payout having a large payout value in the three types of fixed payouts. For example, in the normal game, at the time when the number of bets per one of PAY LINE is "1", whereas the probability that the dividend value is winning the largest "CREDIT _{_} 3" is 100/1000, one of PAY LINE the probability that the "CREDIT _{_} 3" is to win at the time of the number of bets per "5" is 1191/7670, the winning probability is high.

  In this embodiment, seven types of fixed payout tables are provided corresponding to the game settings of V01 to V07. FIGS. 21A to 21C show the fixed payout tables corresponding to the game settings of V01 to V03. Each is shown. In the seven types of fixed payout tables, at least some of the weight values for the fixed payouts set for each bet number set in the base game that triggered the transition to the free game are different from each other. Includes multiple types of fixed payout tables. Therefore, the probability that each fixed payout is won can be changed by selecting any one of the game settings V01 to V07 according to the audit setting.

  In the special payout determination process, as shown in FIGS. 35A and 35B, the display window 250 and the wheel 251 are displayed on the upper image display panel 131. In the present embodiment, the wheel 251 is a video-type wheel that represents, by video, the rotation and stop operations of the mechanical wheel in which a plurality of symbols are drawn on its peripheral surface. A symbol string composed of 16 symbols is assigned to the wheel 251. During the special payout determination process, the wheel 251 is scrolled (variably displayed) as shown in FIG. 35A in the display window 250, and after a predetermined time has elapsed, it stops as shown in FIG. 35B. As a result, any one of the 16 symbols is displayed to the player.

The types of symbols displayed in the symbol row of the wheel 251 correspond to a plurality of types of prizes that can be awarded by the special payout determination process. Specifically, four types of symbols “GRAND”, “MAJOR”, “MINOR”, “MINI” corresponding to four types of progressive payouts, and three types of symbols displayed in the symbol row of the wheel 251 are displayed. a total of seven types of 3 types of symbols of corresponds to a fixed dividend "CREDIT _{_} 1", "CREDIT _{_} 2", "CREDIT _{_} 3". In the present embodiment, the number of these seven types of symbols displayed in the symbol column of the wheel 251 differs depending on the number of bets bet on the base game that triggered the transition to the free game.

  FIG. 22 shows a symbol row of the wheel 251 for each bet number bet per one PAY LINE in the base game that has been triggered by the transition to the free game. As shown in FIG. 22, the ratio of the number of types of symbols associated with a prize having a relatively larger payout value than the other prizes among a plurality of prizes to the total number of symbols arranged in the wheel 251 is free. The larger the number of bets placed in the base game that triggered the transition to the game, the larger the bet. For example, the ratio of the “GRAND” symbol corresponding to “GRAND JACKPOT” having the largest payout value is 2/16 when the number of bets per one PAY LINE in the normal game is “1”. On the other hand, when the bet number bet per PAY LINE in the normal game is “10”, it is 3/16. As a result, when a high bet is betted in the base game, there are many symbols associated with a prize having a relatively higher payout value in the display window 250 while the wheel 251 is variably displayed. Will be displayed. As a result, it is possible to increase the expectation that a high payout will be awarded to the player when the free game ends.

  As described above, whether or not to give the progressive payout before the progressive payout type is determined in the progressive lottery in the progressive payout giving process determined in relation to the establishment of the predetermined condition in the base game. In the progressive lottery stage (a state in which it is not yet determined which type of progressive payout is to be awarded), the more bets bet using the first to fifth BET buttons 38 in the normal game where a predetermined condition is established, The probability of winning a progressive payout in the progressive lottery increases. Thereby, since it is not known when the predetermined condition is satisfied in the normal game, there is a possibility that the player's psychology can be induced to increase the number of bets in the normal game. When a progressive payout is won, fairness for a player with a small number of bets can be ensured by determining the type of progressive payout under the same conditions regardless of the number of bets. As a result, it is possible to provide the slot machine 1 that can correct the unfairness among the players.

  Even if a progressive payout is not won, a fixed payout is awarded according to the number of bets. Therefore, it is possible to differentiate between a player who has bet a high bet and a player who has a small bet. As a result, it is possible to provide a gaming machine that may correct the unfairness among players.

(Program contents)
Next, a program executed by the slot machine 1 will be described with reference to FIGS. 23A to 28.

(Main control process)
First, the main control process will be described with reference to FIGS. 23A and 23B. FIG. 23A is a flowchart when the pre-logon state is selected as the game state of the slot machine 1 by the audit setting, and FIG. 23B is a flow when the prog-off state is selected as the game state of the slot machine 1. FIG. Hereinafter, first, with reference to FIG. 23A, the main control process when the pre-logon state is selected as the game state of the slot machine 1 will be described.

  First, when power is turned on to the slot machine 1, the main CPU 71 reads the authenticated second game program from the SSD device 55 via the gaming board 50 and writes it to the RAM 73 (S11). Thereby, the game state of the slot machine 1 becomes a pre-logon state.

  Next, the main CPU 71 performs an initialization process at the end of one game (S12). For example, unnecessary data for each game is cleared in the work area of the RAM 73, such as the number of bets and symbols determined by lottery.

  Next, the main CPU 71 performs a bet / start check process which will be described later with reference to FIG. 24 (S13). In this process, input checks such as the first BET switch 34S, the second BET switch 35S, the third BET switch 36S, the fourth BET switch 37S, the fifth BET switch 38S, and the spin switch 46S are performed.

  Next, the main CPU 71 performs a symbol lottery process (first lottery) (S14). In this process, the symbol to be stopped is determined based on the random number for symbol determination. In the present embodiment, symbols to be stopped are displayed according to the reels 101 to 105 in accordance with the weights for the 22 symbols corresponding to the code numbers “00” to “21” shown in the second base game symbol table of FIG. Determined by lottery.

  Next, the main CPU 71 performs effect content determination processing (S15). The main CPU 71 extracts an effect random number value and determines one of a plurality of predetermined effect contents by lottery.

  Next, the main CPU 71 performs a symbol display control process (S16). In this processing, scrolling of the reels 101 to 105 is started, and the scheduled stop symbol determined in the symbol lottery processing in S14 is stopped at a predetermined position (for example, a middle region in the display window 150). That is, 15 symbols including the scheduled stop symbol are displayed in the display window 150. In addition, during the symbol display control process, the effect determined by the effect content determination process in S15 is executed.

  Next, the main CPU 71 performs a credit grant number determination process (S17). In this process, referring to the line winning payout table (see FIG. 11) and the second scatter winning payout table (see FIG. 13) stored in the RAM 73, the number of credits awarded based on the line winning or the scatter winning is determined. , Stored in a credit amount storage area provided in the RAM 73.

  Next, the main CPU 71 determines whether or not a free game trigger is established (S18). In the present embodiment, as shown in FIG. 31B, when five or more “BONUS” symbols that are trigger symbols of the free game are rearranged in the display window 150, “free game trigger” is determined as the winning combination. To the free game. When the main CPU 71 determines that the free game trigger is established (S18: YES), the main CPU 71 performs a free game process which will be described later with reference to FIG. 26 (S19), and thereafter, referring to FIG. 28 later. A special payout award process to be described is performed (S20).

  Next, the main CPU 71 determines whether or not there is a payout after the processing of S20 or when it is determined in S18 that the free game trigger is not established (S18: NO) (S21). This determines whether or not a payout has been awarded in the processing of S17, S19 or S20. If it is determined that there is a payout (S21: YES), a credit grant process is performed (S22). The main CPU 71 adds the value stored in the credit amount storage area to the value stored in the credit number storage area provided in the RAM 73. Based on the input of the CASHOUT switch 32S, the main CPU 71 controls the PTS device 700 to write the credit data indicating the value stored in the credit grant number storage area to the IC card inserted into the card insertion slot. But you can. After this process is performed, or when it is determined that there is no payout in the process of S21 (S21: NO), the process returns to S12.

  Next, with reference to FIG. 23B, the main control process when the progress-off state is selected as the game state of the slot machine 1 will be described. The main control process when the progress-off state is selected as the game state of the slot machine 1 is substantially the same as the main control process when the pre-logon state described with reference to FIG. 23A is selected. Only the main differences are described.

  In the main control process, in the process of S <b> 11, the main CPU 71 reads the authenticated first game program from the SSD device 55 via the gaming board 50 and writes it in the RAM 73. As a result, the game state of the slot machine 1 is in the progress-off state.

  In the symbol lottery process of S14, each reel 101-105 is assigned according to the weights for the 22 symbols corresponding to the code numbers “00”-“21” shown in the first base game symbol table of FIG. 8A and FIG. 8B. Accordingly, the symbols scheduled to be stopped are determined by lottery.

  In addition, in the credit granting number determination process in S17, the line winning or scatter winning is determined with reference to the line winning payout table (see FIG. 11) and the first scatter winning payout table (see FIG. 12) stored in the RAM 73. The credit grant number based on this is determined and stored in the credit grant number storage area provided in the RAM 73.

  In the main control process, the main CPU 71 performs a free game (S19), and then proceeds to the process of S21. That is, in the main control process when the game state of the slot machine 1 is the progress-off state, the special payout awarding process is not performed unlike the main control process when the game state is the pre-logon state.

(Bet / start check process)
Next, the bet / start check process will be described with reference to FIG.

  First, the main CPU 71 determines whether or not credit data has been received from the PTS device 700 (S41). The transmission of credit data from the PTS device 700 to the main CPU 71 is performed when an IC card is inserted into the card insertion slot and when the bill entry 60 accepts a regular bill.

  When determining that the credit data has been received (S41: YES), the main CPU 71 adds the amount indicated by the received credit data to the value stored in the credit number storage area (S42).

  The main CPU 71 determines whether or not the value stored in the credit number storage area is 0 after S42 or when it is determined that no credit data is received in S41 (S41: NO) (S43). ). When the main CPU 71 determines that the value stored in the credit amount storage area is not 0 (S43: NO), the BET button (first BET button 34, second BET button 35, third BET button 36, fourth BET button 37). , The operation acceptance of the fifth BET button 38) is permitted (S44).

  Next, the main CPU 71 determines whether or not an operation of the BET button is detected (S45). When the main CPU 71 detects that the BET button has been pressed by the player using the BET switch (first BET switch 34S, second BET switch 35S, third BET switch 36S, fourth BET switch 37S, fifth BET switch 38S), the BET button The value stored in the BET number storage area provided in the RAM 73 is added (updated), and the value stored in the credit number storage area is subtracted (S46).

  Next, the main CPU 71 determines whether or not the value stored in the BET number storage area is the maximum (S47). When the main CPU 71 determines that the value stored in the BET number storage area is the maximum (S47: YES), the main CPU 71 prohibits updating of the value stored in the BET number storage area (S48). After determining that the value stored in the BET number storage area is not the maximum after S48 or S47 (S47: NO), the main CPU 71 permits the operation acceptance of the spin button 46 (S49).

  When the main CPU 71 determines that the operation of the BET button is not detected in S45 after S49 (S45: NO), or determines that the value stored in the credit amount storage area is 0 in S43 (S43: YES), it is determined whether or not the operation of the spin button 46 is detected (S50). When determining that the operation of the spin button 46 is not detected (S50: NO), the main CPU 71 proceeds to S41.

  On the other hand, when the main CPU 71 determines that the operation of the spin button 46 is detected (S50: YES), the main CPU 71 performs a progressive jackpot-related process which will be described later with reference to FIG. 25 (S51). In this process, a part of the bet number bet in the base game is incremented and accumulated cumulatively in the payout amounts of the four types of progressive jackpots. In the present embodiment, a value to be incremented for each of the four types of progressive jackpot payouts is calculated, and the payout amount for each of the four types of progressive jackpots stored in the progressive payout storage area provided in the RAM 73 is updated. . Then, the bet / start check process ends.

(Progressive jackpot-related processing)
Next, the progressive jackpot-related processing will be described with reference to FIG.
First, the main CPU 71 calculates an increment value for each of the four types of progressive jackpot payouts (S71). Specifically, the main CPU 71 calculates the value incremented for each of the four types of progressive jackpot payouts by obtaining the product of the value in the BET number storage area and the increment rate shown in the progressive payout setting table of FIG. To do. For example, when the value of the BET number storage area is “5”, the value incremented to the payout amount of “GRAND JACKPOT” is 5 × 0.0010 (0.10%) = 0.005, “MINI JACKPOT” The value incremented to the payout amount is 5 × 0.0040 (0.40%) = 0.020.

  Next, the main CPU 71 cumulatively adds and increments the increment value calculated in the process of S71 to each of the four types of progressive jackpots stored in the progressive payout storage area provided in the RAM 73. (S72). At this time, as shown in FIG. 33, the main CPU 71 displays a progressive payout screen 440 indicating the payout amount of each updated progressive jackpot on the liquid crystal panel 141 of the topper device 14. When this process is performed, the progressive jackpot-related process is terminated.

(Free game processing)
Next, free game processing will be described with reference to FIG. FIG. 26 is a view showing a flowchart of the free game processing of the slot machine according to the embodiment of the present invention.

  First, the main CPU 71 executes a prize selection process which will be described later with reference to FIG. 27 (S101). In each free bonus game, when one or more “BONUS” symbols are displayed in any of the display windows 150, a dividend corresponding to the number of “BONUS” symbols displayed in the display window 150 is displayed. Is specially granted. In this prize selection process, a reference payout value that is a payout per symbol of “BONUS” displayed in the display window 150 is determined. The determined reference payout value is displayed as an item of [BONUS] one payout on the upper image display panel 131 as shown in FIG.

  Next, the main CPU 71 adds the number of free games of 7 times to the free game number counter of the RAM 73 and stores it (S102). At this time, a message “7 FREE GAMES START” is displayed on the upper image display panel 131.

  Next, the main CPU 71 performs an initialization process at the end of one game, similar to the process of S12 (S103). For example, in a bonus free game, unnecessary data for each bonus free game is cleared in the work area of the RAM 73, such as symbols determined by lottery.

  Next, the main CPU 71 conducts symbol lottery processing similar to S14 (S104). Specifically, first, the main CPU 71 extracts random numbers for symbol determination. Next, the main CPU 71 determines to-be stopped symbols for the reels 101 to 105 by lottery. The main CPU 71 performs lottery according to each of the reels 101 to 105, and determines any of the 22 symbols as a scheduled stop symbol. At this time, the scheduled stop symbol is determined with a probability according to the weight shown in the free game symbol table of FIG. Then, the main CPU 71 stores the determined symbols to be stopped of the reels 101 to 105 in the symbol storage area provided in the RAM 73.

  Next, the main CPU 71 performs an effect content determination process in the same manner as the process of S15 (S105). Next, the main CPU 71 performs a symbol display control process as in the process of S16 (S106).

  Next, the main CPU 71 performs a credit grant number determination process as in the process of S17 (S107). In this process, with reference to the line winning payout table (see FIG. 11) stored in the RAM 73, the payout is determined based on the combination of symbols displayed on the PAY LINE 1 to 30, and the free game provided in the RAM 73. It is stored in the game credit number storage area.

  Further, in S107, the number of “BONUS” symbols displayed in the display window 150 is determined as a result of the symbol display control processing in S106, and a prize selection process described later is performed on the determined number of “BONUS” symbols. In step S211, a value (reference payout value × “BONUS”) multiplied by the reference payout value (payout per “BONUS” symbol displayed in the display window 150) stored in the reference payout value storage area of the RAM 73. Is stored in a free game credit amount storage area provided in the RAM 73.

  At this time, as shown in FIG. 39, “reference payout value × number of symbols of“ BONUS ”= payout” is displayed. For example, when the reference payout value is “50” and the number of “BONUS” symbols is four, “50 × 4 = 200 credits” is displayed on the upper image display panel 131.

  Next, the main CPU 71 determines whether or not retrigger has been established (S108). The retrigger in this embodiment is that five or more “BONUS” symbols are displayed in the display window 150. When determining that the retrigger has been established (S108: YES), the main CPU 71 executes again the prize selection process described later with reference to FIG. 27 (S109). The payout value given by the prize selection process after the retrigger is given in addition to the reference payout value given by the prize selection process at the time of the first free game trigger, and the reference payout value is updated. Therefore, when the retrigger is established, the reference payout value that is a payout per symbol of “BONUS” displayed in the display window 150 increases, which is advantageous to the player.

  Next, the main CPU 71 adds the number of free games of 5 times to the free game number counter of the RAM 73 and stores it (S110).

  When the main CPU 71 determines that retrigger is not established (S108: NO) or after the processing of S110, the main CPU 71 performs free game credit grant processing (S111). In this free game credit awarding process, the main CPU 71 stores the value stored in the free game credit award number storage area in the credit award number determination process in S107 described above in the free game credit total storage area. Add to the value. The free game credit total storage area is an area for storing the total amount of payouts determined during the free game. When the free game process ends, the main CPU 71 stores the value stored in the free game credit total storage area in the credit number storage area provided in the RAM 73 in the credit grant process of S21. Add to the value. That is, the total of the payouts determined in the free game is awarded collectively.

  Next, the main CPU 71 subtracts 1 from the value stored in the free game number counter (S112). Next, the main CPU 71 determines whether or not the value stored in the free game number counter is 0 (S113). When the main CPU 71 determines that the value stored in the free game number counter is not 0 (S113: NO), the main CPU 71 proceeds to the process of S103.

  On the other hand, when it is determined that the value stored in the free game number counter is 0 (S113: YES), the free game process is terminated. When the free game process ends, the process proceeds to a special payout determination process (S20).

(Price selection process)
Next, the prize selection process will be described with reference to FIG. FIG. 27 is a view illustrating a flowchart of the prize selection processing of the slot machine according to the embodiment of the present invention.

  First, the main CPU 71 executes a lottery number determination process (S201). In the lottery count determination process, the main CPU 71 determines how many “BONUS” symbols are rearranged in the display window 150 as a result of the symbol display control process of S16 or S106.

  Next, the main CPU 71 determines the number of lotteries corresponding to the number of “BONUS” symbols determined in the process of S201 with reference to the above-described prize selection table (see FIG. 16). It adds to the lottery number counter of RAM73 (S202). For example, when six “BONUS” symbols are rearranged on the display window 150, the lottery count is added to the lottery count counter with reference to the lottery count table. At this time, as shown in FIG. 37, an image 350 indicating the value of the lottery counter and an image 351 indicating the number of free games to be given are displayed on the upper image display panel 131.

  Next, the main CPU 71 executes roulette display processing (S203). In the roulette display process, the roulette 201 shown in FIG. 38 is displayed on the upper image display panel 131. Thereafter, a description of roulette and a description of the number of lotteries determined in the process of S201 are displayed on the upper image display panel 131.

  Next, the main CPU 71 executes a payout lottery process (S204). Specifically, the main CPU 71 extracts a random number for payout lottery, and determines one area number from 12 area numbers (No. 0 to 11) based on the extracted random number. At this time, the region number is determined by the winning probability according to the weight shown in the prize selection table of FIG.

  Next, the main CPU 71 performs effect content determination processing (S205). The main CPU 71 extracts an effect random number value and determines one of a plurality of predetermined effect contents by lottery.

  Next, the main CPU 71 executes a roulette display control process (S206). In this roulette display control process, the mark 203 is lit and displayed in the clockwise order in each payout area 202 of the roulette 201 shown in FIG. 34, and the rotation of the roulette is displayed. The mark 203 stops in the payout area 202 corresponding to the area number determined in S204.

  Next, the main CPU 71 executes a payout value giving process (S207). In this payout value giving process, the payout value corresponding to the stopped payout area 202 is added to the payout value stored in the reference payout value storage area provided in the RAM 73 and stored. Further, the main CPU 71 executes a total display process of the reference payout value (S208). In the total display processing of the reference payout value, the upper image display panel 131 produces an effect of displaying the payout value stored in the reference payout value storage area updated in the processing of S207.

  Next, the main CPU 71 subtracts 1 from the value stored in the lottery counter (S209). Next, the main CPU 71 determines whether or not the value stored in the lottery counter is 0 (S210). When the main CPU 71 determines that the value stored in the lottery counter is not 0 (S210: NO), the main CPU 71 proceeds to the process of S204. At this time, the main CPU 71 displays the value stored in the lottery counter on the upper image display panel 131 to inform the player of the remaining lottery times.

  On the other hand, when it is determined that the value stored in the lottery counter is 0 (S210: YES), the main CPU 71 executes reference payout value determination processing (S211). In this reference payout value determination process, the payout value stored in the reference payout value storage area of the RAM 73 is used as a reference payout per symbol of “BONUS” displayed on the display window 150 in each bonus free game. Determine the dividend value.

  At this time, a breakdown of values stored in the reference payout value storage area is displayed. Specifically, the payout values given as a result of the lottery corresponding to the number of lotteries given in the process of S201 are individually displayed. For example, when the number of lotteries given in the process of S201 is 2, an image showing the payout value given as a result of the first lottery and the payout value given as a result of the second lottery is displayed.

  If retrigger is established in the process of S108 in the free game process, an image showing the total payout value given at the time of the first free game trigger is displayed, and the process of S201 is performed after the retrigger is established. The payout value given as a result of the lottery corresponding to the number of lotteries given in is individually displayed. Thereafter, the prize selection process is terminated. When the prize selection process ends, the process proceeds to S102 described with reference to FIG.

(Special dividend determination process)
Next, the special payout determination process will be described with reference to FIG. FIG. 28 is a view illustrating a flowchart of the special payout determination process of the slot machine according to the embodiment of the present invention. In the following description, it is assumed that the game setting V01 is selected from the game settings V01 to V07 and the game setting S01 is selected from the game settings SC01 to SC04 by the audit setting.

  First, the main CPU 71 executes a progressive lottery (second lottery) for determining whether or not to give a progressive payout (S301). Specifically, first, the main CPU 71 refers to the blog winning / non-winning table shown in FIG. 17A among the seven types of winning / non-winning tables according to the game setting V01 selected by the audit setting. . Then, based on the program winning / non-winning table shown in FIG. 17A, each of the numbers of 1,0921,300 which is the total value of the weights of the non-winning and winning is associated with either non-winning or winning. At this time, as the number of bets (value stored in the BET number storage area of the RAM 73) bet in the base game that triggered the transition to the free game is increased based on the blog winning / not winning table, Increase the number of numbers associated with. For example, as shown in the progress winning / non-winning table, when the number of bets placed in the base game that triggered the transition to the free game is “1”, the number of bets corresponding to the winning is “1”. "5507494", which is the weight value for winning at the time of "", whereas if the number of bets bet on the base game that triggered the transition to the free game is "10", a numerical value associated with the winning Is set to “55074940”, which is a weight value for winning when the bet number is “10”. Then, the main CPU 71 randomly extracts one of 180921300 numbers as a random number value using a random number extractor (not shown), and gives a progressive payout when the free game ends based on the extracted random number value. Decide whether or not to do. That is, when the extracted random number value is associated with winning, it is determined to give a progressive payout, and when the extracted random value is associated with non-winning, it is determined not to give a progressive payout. As described above, in this progressive lottery, as shown in the progressive winning / non-winning table, the progressive bet is won as the number of bets placed in the base game that triggered the transition to the free game increases (progressive payout is awarded). The probability is high).

  As a result of the progressive lottery in S301, when it is determined that a progressive payout is to be awarded (S302: YES), a progressive rank lottery (third lottery) for determining any one of the four types of progressive payout is executed. (S303). First, the main CPU 71 refers to the progressive payout table shown in FIG. 19A among the four types of progressive payout tables in accordance with the game setting S01 selected by the audit setting. Then, based on the progressive payout table shown in FIG. 19A, each of the 10,000 numerical values, which is the total value of the four types of progressive payout weights, is associated with one of the four types of progressive payouts. At this time, as shown in the progressive payout table, regardless of the bet number (value stored in the BET number storage area of the RAM 73) in the base game that triggered the transition to the free game, four types of progressive The number of numbers associated with each dividend is unchanged. For example, as shown in the progressive payout table, the number of numerical values corresponding to “GRAND JACKPOT” regardless of whether the bet number betted in the base game that triggered the transition to the free game is “1” or “10”. Is “80” which is a weight value for “GRAND JACKPOT”. Then, the main CPU 71 randomly extracts one of 10000 numerical values as a random value by a random number extractor (not shown), and selects one of the four types of progressive payouts based on the extracted random value. Determine one. For example, when the extracted random number value is associated with “GRAND JACKPOT”, “GRAND JACKPOT” is determined, and when the extracted random number value is associated with “MINOR JACKPOT”, “MINOR JACKPOT”. To decide. As described above, in the progressive rank lottery, as shown in the progressive payout table, among the four types of progressive payouts, the winning probability remains unchanged regardless of the number of bets bet on the base game that triggered the transition to the free game. Any one of these will be determined.

On the other hand, when it is determined that the progressive payout is not awarded as a result of the progressive lottery in S301 (S302: NO), a fixed payout rank lottery for determining any one of the three types of fixed payouts is executed ( S304). First, the main CPU 71 refers to the fixed payout table shown in FIG. 21A among the seven types of fixed payout tables in accordance with the game setting V01 selected by the audit setting. Then, based on the fixed payout table shown in FIG. 21A, three types according to the number of bets (values stored in the BET number storage area of the RAM 73) betted in the base game that triggered the transition to the free game. Each number corresponding to the total number of fixed payout weights is associated with one of the three types of fixed payouts. At this time, as shown in the fixed payout table, the payout value increases with an increase in the number of bets (value stored in the BET number storage area of the RAM 73) in the base game that triggered the transition to the free game. The probability of winning a fixed dividend with a large is high. For example, as shown in the fixed payout table, when the number of bets bet in the base game that triggered the transition to the free game is “1”, the total value of three types of fixed payout weights is 1000 of the number of numeric values to be associated with the largest "CREDIT _{_} 3" is dividend value of the numerical value to "100". On the other hand, when the number of bets that have been bet in the normal game that triggered the transition to the free game is "10", of the 1200 pieces of numerical value is the sum of the weights of the three types of fixed dividend "CREDIT _{_} The number of numerical values associated with “3” is “327”. As a result, is better when the number of bets that have been bet is "10" than in the case of "1" in the normal game, the probability of winning is "CREDIT _{_} 3" is higher. Then, the main CPU 71 randomly extracts one of the same numbers as the total value of the three types of fixed payout weights using a random number extractor (not shown) as a random number, and based on the extracted random number, 3 One of the types of fixed dividends is determined. For example, when the extracted random number values were associated with "CREDIT _{_} 1" if that was associated with the "CREDIT _{_} 1" determines the extracted random number value is "CREDIT _{_} 3" is " CREDIT to determine the _{_} 3 ". As described above, in this fixed payout rank lottery, the greater the number of bets placed in the base game that triggered the transition to the free game, the higher the probability that a fixed payout with a higher payout value will be won.

  The main CPU 71 executes a wheel display control process after S303 or after S304 (S305). Specifically, the main CPU 51 displays the display window 250 and the video wheel 251 on the upper image display panel 131. At this time, the 16 symbols to be displayed on the wheel 251 are stored in the BET number storage area of the RAM 73 (see the BET number storage area of the RAM 73) as shown in FIG. Value).

  Then, the main CPU 51 scrolls the wheel 251 in the display window 250 as shown in FIG. 35A, and after the predetermined time has elapsed, as shown in FIG. 35B, the free game is ended in the process of S303 or S304. The symbol type corresponding to the payout determined to be sometimes given is stopped and displayed on the display window 250. As a result, the player can grasp the type of award awarded as a special payout.

  Next, the main CPU 71 conducts credit amount determination processing (S306). In this process, the number of credits awarded based on the progressive payout determined in the progressive rank lottery process of S303 or the number of credits awarded based on the fixed payout determined in the fixed payout rank lottery process of S304 is determined and provided in the RAM 73. It is added to the value stored in the credit grant number storage area. Note that the number of credits awarded based on the progressive payout determined in the progressive rank lottery process is a payout amount corresponding to the progressive payout stored in the progressive payout storage area. In addition, when the main CPU 71 grants any of the four types of progressive payouts as the special payout, the main CPU 71 sets the payout amount corresponding to the progressive payout stored in the progressive payout storage area to the progressive initial payout value. initialize. Thereafter, the special payout determination process is terminated. When the special payout determination process ends, the process proceeds to S21 described with reference to FIG. 23A.

  The embodiment of the present invention has been described above, but only specific examples are illustrated, and the present invention is not particularly limited.

The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.

  For example, in the above-described embodiment, when the progressive payout is not won in the special payout determination process, a fixed payout is provided. However, when the progressive payout is not won, the fixed payout is fixed. It may be configured not to award any prize including a special payout. In addition, when the progressive payout is not won, a predetermined fixed payout may be uniformly given.

  In the above-described embodiment, the progressive payout amount is an amount obtained by accumulating a part of the number of bets placed in one slot machine 1. However, the progressive payout amount is determined between a plurality of slot machines 1. May be an amount obtained by linking a part of the number of bets placed in each of the plurality of slot machines 1. That is, the progressive payout amount may be shared among a plurality of slot machines 1. At this time, for example, each slot machine 1 is configured to transmit the bet amount for each base game to the external control device 200, and the external control device 200 (see FIG. 3) manages the progressive payout amount. May be.

  Further, the special payout determination process is configured to be executed after the free game process is completed, but may be executed anytime after the free game trigger is established in the normal game. Accordingly, a prize determined by the special payout determination process may be awarded during the free game. Further, the special payout determination process may be executed when another condition different from the condition that the free game trigger is established is established in the base game.

  In the above-described embodiment, the flash memory 54 of the SSD device 55 stores two types of the first game program and the second game program. Then, the main CPU 71 selects one of the two types of game programs based on the audit settings as a game program to be read from the flash memory 54 and written to the RAM 73 when the slot machine 1 is powered on. The game state of the slot machine 1 is configured to be switched between the pre-logon state and the prog-off state. However, the present invention is not limited to this, and the game state of the slot machine 1 is changed to the pre-logon state according to the audit setting. What is necessary is just to be comprised so that it can switch between progress-off states. For example, the flash memory 54 of the SSD device 55 stores only one type of game program including settings relating to both the pre-logon state and the prog-off state. The main CPU 71 reads out this one type of game program from the flash memory 54 and writes it into the RAM 73 when the slot machine 1 is powered on. At this time, various tables related to the pre-logon state and the prog-off state described above are also stored in the RAM 73. And even if it is comprised so that the game state of the slot machine 1 may be switched between a pre-logon state and a prog-off state by selecting whether the setting which uses a pro-logon state or a pro-logoff state is used by an audit setting.
