Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a slot machine, and more particularly to a slot machine that can carry over winning of a plurality of special roles.
[0002]
[Prior art]
In a conventional slot machine, when all the reels are started simultaneously by operating a start lever, an internal lottery of a role is performed by a control unit in the slot machine, and when a lottery is won (hereinafter, referred to as a winning), the reel is reeled. If the winning symbol is within a predetermined range when the stop operation is performed, the pull-in control of the reels is performed, and the pull-in stop control is performed so that the winning symbols are aligned on a winning line (hereinafter, referred to as a prize). . If the symbol lottery is not selected, reel stop control is performed so that the winning symbol is not won.
[0003]
In the lottery of a winning combination, a random number value is extracted, and it is determined whether the extracted random number value belongs to a winning area of any of the winning combinations, thereby determining the winning or non-winning of the winning combination. When a small role or a replay is won in the game, the winning of the small role or the like is valid only for the game, and the winning is not carried over after the next game. On the other hand, when the bonus combination is won, the winning of the bonus combination is carried over after the next game until the bonus combination is won. Then, in the game after the winning of the bonus role, until the winning of the bonus role, even if the extracted random number value belongs to the winning area of the bonus role, the random number value is determined to be non-winning and is not double won for the bonus role. .
[0004]
However, recently, as disclosed in Japanese Patent Application Laid-Open No. 2002-272913, when a bonus combination is won, a bonus flag is set, and the bonus flag is stocked. There is a slot machine provided with a so-called stock mode (hereinafter, referred to as a replay time game: an RT game) in which the machine determines whether to release the game.
[0005]
In the RT game, the winning probability of the replay is set to be much higher than in the normal gaming state, but the player is not aware that the winning probability is high. In this slot machine, if the release of the bonus flag is set, for example, after 300 games, the pull-in control is performed after 300 games.
[0006]

[0007]
[Problems to be solved by the invention]
When releasing the above-mentioned bonus flag, it is necessary to notify the player of this fact. However, direct notification has a problem that the interest of the game is lacking.
[0008]
Therefore, a main object of the present invention is to provide a precursory effect to display the number of games until the special role can be awarded in a slot machine in which the special role is carried over, and to bore the game. The goal is to provide a slot machine that can excite the player's expectations.
[0009]
[Means for Solving the Problems]
The present invention is a slot machine for performing an internal lottery of a role, winning the special role, stocking the special role, and displaying in advance a time for releasing the next special role, and a slot machine for displaying the next special role. Display means for displaying an indication effect indicating a timing of releasing the game, and a table determined in advance based on the number of remaining games until the next special role winning possible state when an effect lottery for the indication effect is performed and a winning is won. And control means for displaying the movement of the indication effect on the display means.
[0010]
In this way, when the special role is stocked, the player performs the precursor effect indicating the timing of releasing the next special role, so that the player can estimate the time when the special role will be released from the mode of the precursor effect. Is possible, and the interest can be enhanced.
[0011]
More preferably, the table specifies one of the effect drawing lottery tables including a plurality of effect setting lottery tables including a plurality of tables set according to the number of remaining games until the special role becomes a winning state, and for each effect pattern. Information, and an indication effect table that stores an effect level indicating the movement of the indication effect, wherein the control means performs a production lottery and wins, based on the number of games remaining until the special role becomes a winning possible state. One of the effect lottery tables is determined, the effect pattern is determined using the table, and the movement of the precursor effect is displayed on the display means based on the corresponding effect level. As a result, the number of remaining games, information for designating a table, and the like can be freely set to arbitrary values.
[0012]
Preferably, the precursor effect table stores the number of values representing the probability of being selected corresponding to each of the effect lottery tables for each effect pattern, and the control means controls the effect level corresponding to the effect pattern based on the effect lottery result. , The movement of the indication effect is displayed on the display means with a probability based on the number of values. Thereby, it is possible to arbitrarily set and store the number of values indicating the probability of being selected corresponding to the effect lottery table, the effect level and the like.
[0013]
Further preferably, it includes a sound notifying means for notifying the sound, and the control means notifies the sound from the sound notifying means at a volume corresponding to the effect level. This makes it possible to produce an aura as well as visually.
[0014]
Preferably, when the control unit wins the effect lottery, the control unit does not perform the effect lottery until a predetermined number of games are finished thereafter. As described above, the effect lottery is not performed until the predetermined number of games is completed, so that the precursor effect can be set for each predetermined number of games.
[0015]
Further, preferably, the number of games remaining until the next special combination winning state is set as a value in a plurality of ranges or a fixed value in the effect lottery table. Thereby, it is possible to freely set the number of remaining games until the next special role winning state indicated according to the effect number.
[0016]
Further preferably, the display means is constituted by a dot display, and the control means displays an image of a pattern corresponding to the effect level on the dot display and increases the sound level emitted from the sound notifying means. In this way, by making an indication by dot display and sound notification, it is possible to visually and audibly increase the degree of expectation of the special role for the player.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is an external view of a slot machine according to an embodiment of the present invention, FIG. 2 is a diagram showing reel symbols, and FIG. 3 is a diagram showing symbol arrays.
[0018]
In FIG. 1, a slot machine forms a symbol display section 3 in which three vertically long reel display windows 4 are arranged side by side on a front panel 2 provided on a front surface of a housing 1, and each reel is provided in the housing 1. A configuration in which three reels 5 are arranged corresponding to the formation positions of the display windows 4 is general.
[0019]
On the outer peripheral surface of each reel 5, a plurality of types of symbols, such as red 7, blue 7, BAR, watermelon, bell, cherry, replay, etc. as shown in FIG. As shown in the figure, the reel tape is displayed at random. While the reels 5 are rotating, the symbols displayed on the respective outer peripheral surfaces appear one after another in the reel display window 4. On the other hand, when the reels 5 are stopped, the symbols for each of the reels 5 are, for example, three frames. Are displayed in a line up on five stop lines L... Set on the symbol display section 3, which are upper, middle, lower, rising right and lower right. In addition to the ordinary circular reel, a liquid crystal display or a reel tape wound around a pulley and circling may be used.
[0020]
The stop line L is sequentially activated according to the number of inserted medals inserted from the medal insertion slot 6. For example, when one medal is inserted, one horizontal stop line L at the center is valid, and when two medals are inserted, three horizontal, upper, middle, and lower stop lines L are used. Becomes effective, and when three medals are inserted, all five stop lines L... Become effective. After the three reels 5 start rotating by operating the lever 7 provided on the lower projecting surface of the front panel 2, the stop button 8 provided corresponding to each reel 5 is pushed. For example, three reels 5 stop sequentially. At this time, if a specific combination of symbols is arranged on the stop line L... Which is enabled by the number of inserted medals, a winning according to the combination of symbols is established, and a predetermined number of winnings determined according to the type of the winning are achieved. Medals will be paid out.
[0021]
An upper lamp 14, a speaker 13, and a dot display 16 are arranged on an upper front surface of the housing 1. The upper lamp 14 and the speaker 13 perform predetermined effects during the game, respectively. The upper lamp 14 lights up in a predetermined pattern when a predetermined condition is satisfied during the game, and the speaker 13 emits a predetermined sound. Is output. The dot display 16 is provided for displaying a precursor indicating the number of games before the remaining game before the occurrence of the bonus game, which is a feature of the present invention, at the effect level indicating the effect display pattern.
[0022]
By the way, the slot machine extracts a random number generated by the random number generator of the control unit every time the lever 7 is operated or at the start of reel rotation (hereinafter referred to as a game start), and the extracted random number is won. An internal lottery is performed, and if the extracted random number has been won, a stochastic method is adopted in which a combination of symbols to be arranged on the activated line is determined according to the random number. Then, when an internal lottery is won, a flag is given (a so-called "flag is raised").
[0023]
Actually, if the flag is not set, a specific combination of symbols cannot be aligned, even if the timing of pressing the stop buttons 8... Is correct. Conversely, when the flag is set (understood), a specific combination of symbols can be aligned as long as the timing of pressing the stop buttons 8... Is correct.
[0024]
The paid-out medals and medals inserted in excess of three medals are deposited in the housing 1 and the number of deposited medals is displayed on the medal storage number display unit 9.
[0025]
The BET button 10 provided on the overhanging surface consumes one to three medals by the operation of the push button, and the settlement button 11 is used to settle the stored medals and receive a payout from the medal outlet 12. belongs to.
[0026]
FIG. 4 is a block diagram showing an electrical configuration of the slot machine according to one embodiment of the present invention. The slot machine includes a CPU 26 which is a main body of control and calculation regarding game contents, a ROM 27 which stores a game control program and tables shown in FIGS. 6 to 8 described later, a RAM 28 used for reading and writing data, and a random number generator 29. The main controller 25 is provided. Various input / output units are connected to the CPU 26 via a bus 30.
[0027]
The input unit includes a lever 7, three stop buttons 8,..., A BET button 10, a settlement button 11, a medal insertion sensor 31 for detecting the number of medals inserted from the medal insertion slot 6, and the like. The data is input to the CPU 26 via the bus 30. The output unit includes a reel drive unit 32 that starts, stops, and pulls in the three reels 5..., A medal payout unit 33 that pays out medals according to the type of winning, and the like. A control signal is provided from the CPU 26 via the CPU 26.
[0028]
Further, the slot machine includes a sub-control unit 35 having a CPU 36, which is a main body of control, effect display, and control of the peripheral output unit, a ROM 37 in which various control programs are stored, a RAM 38 used for reading and writing data, and a random number generator 39. Have. The sub-control unit 35 is connected to the buses 30 and 40 and receives various control signals from the main control unit 25. The CPU 36 is connected with various lamps such as the upper lamp 14 and the backlight 15, the dot display 16, and the speaker 13 via the voice control board 41, and the various lamps are placed under the control of the CPU 36.
[0029]
FIG. 5 is a diagram showing a combination of symbols on three reels.
[0030]
As described above, the slot machine configured as described above employs the probability method of determining winning / non-winning by performing a lottery for each game. Two types of winning are set: special winning and other small winning.
[0031]
As a special prize, for example, as shown in FIG. 5 (a), "7-7-7" is completed and 15 medals are paid out, for example, "Big Bonus (hereinafter referred to as BB) prize". As shown in (b), there is a “regular bonus (hereinafter referred to as RB) prize” in which, for example, 15 medals are paid out when “BAR-BAR-BAR” is completed. In addition, there is a single bonus (hereinafter, referred to as SB) in the special winning, but it is assumed that no SB is provided in this embodiment.
[0032]
When the RB winning is established, a plurality of JAC games can be played. The JAC game is a game in which one medal is inserted to play the game, and, for example, as shown in FIG. 5C, if three replay (hereinafter referred to as RP) symbols are arranged, for example, 15 medals are paid out. The RB game is ended when one of the conditions of winning the JAC game eight times or of performing the JAC game 12 times is satisfied.
[0033]
When the BB prize is established, a small win game in which the small win is easy to win and a plurality of RB games can be performed. In the small win game, for example, if the JAC symbols as shown in FIG. The BB game is ended when one of the conditions when the small role game is played 30 times or when the RB game is played three times is satisfied.
[0034]
When the player wins the small role, a predetermined number of medals are paid out, and as shown in FIG. 5D, eight medals are paid out by aligning three bell symbols, and FIG. As shown in FIG. 5, two medals are paid out by displaying one cherry symbol, and as shown in FIG. 5G, a medal is not paid out even when three watermelon symbols are arranged. Is set.
[0035]
When three RP symbols are aligned as shown in FIG. 5 (f), there is no payout of medals, and instead, the number of medals to be inserted in the game is maintained and a re-game can be performed. In this embodiment, when the three watermelon symbols are completed, they are treated as small wins for a bonus indication effect.
[0036]
Incidentally, the pull-in control of the reel 5 must be performed within a predetermined time due to legal restrictions, and as a result, the number of frames that can be drawn is limited (so-called "slip", usually a maximum of four frames). Therefore, unless the stop button 8 is pressed within the allowable range of the slip, the winning symbol cannot be stopped on the activated line. Whether or not a prize has been won (the flag is on) can be known by a flag notification or a stop symbol (a so-called reach eye).
[0037]
In the slot machine configured as described above, every time the lever 7 is operated, the random number generated by the random number generator 29 of the main control unit 25 is extracted, and whether or not the extracted random number has won a special role is determined. After the determination and the winning of the special combination, it is determined how many games the bonus flag is released after, and a control state in which a bonus prize cannot be won during the game is set. If the internal lottery of the bonus flag is won during this game period, the bonus flag is stocked by the number of the winning.
[0038]
In the present invention, in order to display how many games before the next special role can be won, various patterns are displayed using the dot display 16 to notify the number of games until the winning is permitted. The omen direction to do is done. By performing such an effect, it is possible to excite the player's expectation without causing boredness in the normal game.
[0039]
In this predictive effect, the bonus is determined if the predictive effect is performed 5 times in a row, and the more the predictive effect pattern displayed in dots is, the higher the sense of expectation is. If the predictive effect of the same content continues three times, the bonus is determined. The basic principle is to do. Therefore, regardless of whether the content of the dot display pattern is flashy or plain, the bonus is determined when the precursor effect of the same content occurs three times, and the expectation of the bonus does not disappear even if the plain effect occurs.
[0040]
The indication effect is performed when the lever 7 is operated by the player, and when the extracted random numbers are won, the indication effect is started. The precursor effect is one set of seven games, and the subsequent seven games are in the precursor effect after the winning game. It should be noted that during the indication effect, no indication effect lottery is performed.
[0041]
In the indication effect, a random number is extracted when the lever 7 is operated. First, an effect drawing table 50 shown in FIG. 6 is determined. In FIG. 6, the effect lottery table 50 is provided with seven types of a release A table, a release B table, a fake table, a precursor effect A table, a precursor effect B table, a precursor effect C table, and a normal table. These production lottery tables 50 are determined by referring to the number of games remaining until the next bonus prize possible state. However, the fake table performs a lottery after the end of the bonus, and after winning, is referred for the next 15 games.
[0042]
The release A table is a lottery table that is referred to before the prize-possible states 1 to 6, and 8 to 15 games. It is characterized that a precursor effect with high expectation of the bonus is likely to appear. The release B table is a lottery table that is referred to seven games before the bonus prize possible state game, and is characterized in that an effect that determines a bonus is more easily selected than the release A table. The fake table is a lottery table referred to by 2/5 after the end of the BB and by 4/5 after the end of the RB, and is referred to for 15 game periods. This fake table is characterized in that an effect similar to the release A table is likely to occur, and an effect with a high expectation of the bonus is generated, but of course the bonus is not fixed.
[0043]
The precursor effect A table is a lottery table referred to 16 to 100 games before the bonus prize possible state, and is characterized as having an effect content that appears only in the precursor effect A table. The precursor effect B table is a lottery table that is referred to before the bonus possible state 101 to 185 games, and is characterized as having an effect content that appears only in the precursor effect B table. The precursor effect C table is a lottery table that is referred to before the bonus possible state 186 to 270 games, and is characterized as having an effect content that appears only in the precursor effect C table.
[0044]
The normal table is a lottery table referred to in games other than 16 to 270 which are not referred to in the indication effects A to C tables, and effects with a low bonus expectation tend to occur, and effects with a high bonus expectation rarely occur. It has been characterized.
[0045]
FIG. 7 is an example of the indication effect table 60, FIG. 8 is a list of the effect levels, FIG. 9 shows a display example of the indication effect level 1 pattern, and FIG. 10 is a table of the indication effect level 3 pattern. FIG. 11 is a diagram showing a display example of a pattern of a sign effect at level 6, and FIG. 12 is a diagram showing a display example of a pattern of a sign effect at level 10.
[0046]
The effect lottery table 50 shown in FIG. 6, the precursor effect table 60 shown in FIG. 7, and the effect level list shown in FIG. 8 are respectively written in the ROM 37 of the sub-board 35 shown in FIG. ing.
[0047]
The indication effect table 60 illustrated in FIG. 7 includes the number of effect games 1 to 7 corresponding to the effect numbers 1 to 131, the release A table of the effect lottery table 50 illustrated in FIG. I remember. Numerical values 1 to 14 of the number of effect games represent the effect levels shown in the effect level list of FIG. When the effect level is high, the movement of the pattern displayed on the dot display 16 is flashy, and the volume of the sound to be notified is also increased.
[0048]
This allows the player to visually and audibly increase the expectation of winning the special role. Since the release A table is set to effect numbers 5 to 7, 13 to 16, 20 and effect numbers 21, 26,... Not shown, the table is selected with a probability of the number of values set for each effect number of 30573 in total. You. For example, since the number of values in the release A table for the effect number 5 is set to 1500, a predictive effect is generated based on the effect levels set for the effect game numbers 3 to 6 for the effect number 5 with a probability of 1500/30573. Will be done.
[0049]
At the effect level 1 used in the precursor effect, the display pattern of the dot display 16 is set to a plain effect in which the visual movement is small and no effect sound is generated when the effect is generated, for example, as shown in FIG. One or two bubbles are generated from the lower left of the screen, and a pattern of rising to the sea surface is displayed or no effect is produced. At the effect level 2, although not shown, a pattern in which three bubbles are generated is displayed.
[0050]
At the effect level 3, visual movements are larger than at the levels 1 and 2, an effect sound is also generated when the effect is generated, and it is transmitted to the player that the reliability is high. For example, as shown in FIG. A pattern in which one fish swims from left to right or one fish swims from right to left is displayed. At the effect level 4, although not shown, a pattern in which one fish swims from the back to the left or from the upper right to the upper left, or a pattern in which two fish swim from the left to the right or from the right to the left is displayed. At the effect level 5, although not shown, a pattern in which three fish swim from left to right or right to left is displayed.
[0051]
From the production level 6, various characters other than small fish appear, and the production sound is also a sound adapted to each character. For example, one fish appears from the right side of the screen as shown in FIG. After eating, a pattern that returns to the right again, or a jellyfish appears from the upper side of the screen, and appears to return to the upper side again after drifting in the center. When the effect level 7 is the angler's pattern, at the level 8 is a fish school pattern, and when the effect levels 9 to 11 occur, the bonus is determined. In the next game in which the effect level 9 occurs, the bonus is always in a state where the bonus can be won. For example, an octopus or sunfish pattern is displayed.
[0052]
The effect level 10 is the same as the effect level 9 in which the bonus is determined. However, the bonus is not always made available in the next game. For example, as shown in FIG. 12, the pattern of the crab or the seahorse is changed. Is displayed. The production level 11 is a production in which the bonus is determined as in the case of the levels 9 and 10, but the bonus is not always in a state where the bonus can be won in the next game, for example, a pattern in which one fish swims from the back to the right. Is displayed. The effect level 12 displays a large fish pattern, and does not occur unless an effect lottery is performed using the precursor effect C table. When the effect level 12 occurs, the remaining 186 to 270 games remain until the next bonus.
[0053]
The effect level 13 displays a turtle pattern, and does not occur unless an effect lottery is performed using the precursor effect B table. When the effect effect of the effect level 13 occurs, 101 to 185 games remain until the next bonus prize. It becomes. The effect level 14 displays a squid pattern, and does not occur unless an effect lottery is performed using the precursor effect A table. When the precursor effect of the effect level 14 occurs, the remaining 16 to 100 games remain until the next bonus prize. It turns out that. In the effects with the effect numbers 1-4, 8-12, 14, and 17-19, there is no occurrence other than the release A / B table, and in the effects with the effect numbers 121-131, the precursor effects A, B, C It is set so that it does not occur except for tables.
[0054]
Next, an example of the sign effect will be described with reference to the sign effect table 60 shown in FIG. For example, if the player has won an effect lottery and the number of remaining games is five, the release A table of the effect lottery table 50 shown in FIG. Is determined. For example, effect number 5 is determined with a probability of 1500/30573. However, since no effect level is set between the first and second games corresponding to the effect number 5, no effect display is performed. In the 3-6 game, 3-6 is set as the effect level, so that the indication effect pattern is displayed on the dot display 16 at the effect levels 3-6 shown in FIG.
[0055]
For example, at the effect level 3, as shown in FIG. 10, a pattern in which one fish swims from left to right or from right to left is displayed, and at the effect level 4, one fish moves from the back to the left or from the top. A pattern in which the two fish swim leftward or rightward to left or swim left to right is displayed. At the effect level 5, a pattern in which three fish swim from the right or left is displayed, and in the effect level 6, a pattern in which jellyfish is swimming or a pattern in which fish are eating food is displayed.
[0056]
FIG. 13 is a diagram illustrating an example of the effect lottery at the time of the normal time and the time of the bonus release.
[0057]
Normally, as shown in FIG. 13 (a), when the production lottery of whether or not to produce a performance is not performed, the production display is not performed. When the production lottery is won, the production display is performed for seven games based on the selected production number. Is performed, the player can predict which table he is currently at, and predict how many games the bonus game will come after. No effect lottery is performed during these seven games. This operation is repeated.
[0058]
FIG. 13 (b) shows an example of bonus release. If the player wins the drawing lottery of the precursory effect A table in the next game after deviating from the effect lottery, the precursory effect A table is selected when the remaining 16 to 100 games are left. No bonus release is performed at this time. Thereafter, an effect display for seven games is performed, and during this time, the effect lottery is not performed. After that, the game goes out of the production lottery twice, this time the production lottery is won, and the release A table is determined based on the number of release games at that time. After that, the player loses the production lottery, wins the production lottery, and determines the release B table based on how many games remain until the next bonus winning state at that time. If the release B table is determined, the release B table is released after the remaining seven games. Therefore, when the RT game ends, a bonus is released.
[0059]
FIG. 13 (c) shows that after the game is deviated from the production lottery, the next game wins the production lottery of the precursor production A table, the production is displayed for seven games, the production is deviated twice, and then the production lottery is won. The process up to the point where the release A table is determined based on the number of games remaining until the next bonus winning possible state at that time is the same as the description of FIG. 13B. Thereafter, after performing the effect display for seven games, the player loses the production lottery, loses the seven game production lottery, and subsequently wins the production lottery. When the release A table is determined based on the number of released games at that time, Bonus release is performed after 6 games.
[0060]
Through this series of effect displays, it is possible to know when the player is currently at any table and when the bonus is released while playing the game.
[0061]
When the random number indicates the effect number 9, as shown in the indication effect table 60 in FIG. 7, no effect display is performed since no effect level is set between the first and second games. In the 3-7 games, the effect levels 2, 3, 4, 5, and 7 shown in FIG. 8 are set as the effect levels, so that the indication effect pattern is displayed on the dot display 16. In this case, since the player knows that the table is the release B table, the player can know that the bonus is enabled seven games before as described with reference to FIG.
[0062]
If the random number indicates the effect number 123, the effect levels 2, 3, and 12 shown in FIG. Is displayed. In this case, the indication effect C table is used, and the player can know that the bonus is enabled after 186 to 270 games.
[0063]
FIG. 14 is a flowchart for explaining the overall operation of the slot machine in one embodiment of the present invention, FIG. 15 is a flowchart showing a subroutine in the general game of FIG. 14, and FIG. FIG. 17 is a flowchart showing a subroutine of the pull-in control, FIG. 17 is a flowchart showing a subroutine of the RT number determination process of FIGS. 14 and 16, FIG. 18 is a flowchart showing a subroutine of the RT game of FIG. 14, and FIG. FIG. 20 shows a subroutine of the indication effect process of FIG. 18, FIG. 20 shows a lottery probability table, and FIG. 21 shows a distribution probability table.
[0064]
In a step SP1 shown in FIG. 14 (abbreviated as SP in the figure), the main control unit 25 sets a flag G indicating whether a general game or an RT game is in progress, a count value S indicating the number of BB flag stocks, and after the end of the BB game. Then, “0” is set in the RAM 28 as an initial value of each of the number of games N until the next BB or RB winning is allowed and the number of effect games C. In step SP2, the main control unit 25 determines whether or not a bonus symbol has been prepared and determines whether or not a bonus has been won. If not, the flag G is set to "0" indicating that a general game is being performed in step SP3. It is determined whether or not it is set, and if it is set to "0", the processing of the general game is performed in step SP4. In step SP3, if "1" is set as the flag G instead of "0", the process of the RT game is performed in step SP5.
[0065]
When the main control unit 25 determines in step SP2 that a bonus prize has been won, the main control unit 25 performs a bonus game process in step SP6, and sets the count value S indicating the number of BB flag stocks to “0” in step SP7. It is determined whether or not it has been set. If it has been set to "0", the process returns to step SP2, and if it has not been set, the process of determining the number of RTs is performed in step SP8.
[0066]
Next, a subroutine process of the general game operation of FIG. 14 will be described with reference to FIG. In a general game, a player inserts medals into the medal insertion slot 6 shown in FIG. 1 or activates the activated line by operating the BET button 10 and operates the lever 7. In step SP11, it is determined whether or not the start operation has been performed. When the main control unit 25 determines that the start operation has been performed, in step SP12, it is determined whether or not the flag S is set. When the flag S is not set, that is, when the number of BB flag stocks is “0”, the main control unit 25 extracts a random number value from the random number generator 29 in step SP13, and the general game in the lottery probability table shown in FIG. The internal lottery is performed based on the lottery probability at the time.
[0067]
In FIG. 20, the lottery probability table has BB, RB, three types of small wins (watermelon, bell, cherry) and RP as winning symbols. The lottery probability at the time of the RT game is determined. The random number value selected when the lever 7 is operated by the player is compared with the random selection probability table to determine the winning combination corresponding to the area to which the random number value belongs. For example, if the randomly selected random value belongs to the BB lottery area, it is determined that the BB has been won, and if it belongs to the non-lottery area, it is determined that it has not been won.
[0068]
In this lottery probability table, as a lottery probability in a general game and a lottery probability in an RT game, for example, the BB lottery probability is 1/150, the RB lottery probability is 1/1200, and the watermelon lottery probability is 1/100. , Bell's lottery probability is set at 1/10 and Cherry's lottery probability is set at 1/150. Is set to 1 / 1.143, which is a much higher value.
[0069]
After performing the internal lottery in step SP13, the main control unit 25 performs bonus symbol non-pull-in control in step SP14. This bonus symbol non-pull-in control is processed according to a subroutine shown in FIG. If it is determined in step SP12 that the flag S has been set and the bonus flag is stocked, then in step SP15, the control for pulling in the bonus symbols is performed, and then the normal game ends.
[0070]
Next, the bonus symbol non-pull-in control operation shown in FIG. 15 will be described with reference to FIG. In step SP21, the main control unit 25 determines whether or not the bonus flag is established, and if the bonus flag is established, sets the flag G to "1" in step SP22. Then, in step SP23, the main control unit 25 sets the count value S indicating the number of stocks of the BB flag to "1", and performs a RT number determination process in step SP24.
[0071]
In this RT number determination process, as shown in the subroutine of FIG. 17, in step SP31, an RT distribution section is randomly selected based on the distribution probability table shown in FIG. Then, in step SP32, the number of RTs is determined with an equal probability, and after the BB game is completed, the processing is performed by setting the number of games N until the winning of the next BB or RB is permitted, and the RT number determination processing ends. .
[0072]
In step SP25 shown in FIG. 16, control for pulling in a lost symbol (kick-off control for a winning symbol) is performed. If the bonus flag has not been established in step SP21, it is determined in step SP26 whether or not another flag has been established. If the flag has not been established, the process proceeds to step SP25. If the flag has been established, the process proceeds to step SP27. The symbol pull-in control for the flag is performed, and the bonus symbol non-pull-in control ends.
[0073]
Next, the RT game shown in FIG. 14 will be described with reference to FIG. The RT game is processed if the flag G is set to "1". In step SP41, it is determined whether or not the lever 7 is operated to perform a start operation. If it is determined that the start operation has been performed, the value of the number of games N until the winning of the next BB or RB is allowed after the BB game is ended in step SP42 is set to “−1”. In step SP43, it is determined whether or not the number of games N is "0". If the number of games N is 0, the flag G is set to "0" to indicate that a general game is being played in step SP50. The 14 RT games are ended.
[0074]
If the remaining game number N is not "0" in the above-mentioned step SP43, it is determined that the RT game in which the bonus flag is not permitted is not ended, and in step SP44, the lottery at the time of the RT game in the lottery probability table shown in FIG. An internal lottery is performed based on the probability. In step SP45, a sign effect process shown in FIG. 19 is performed. That is, in step SP61 shown in FIG. 19, it is determined whether or not the effect game number C is “0”. If not “0”, the effect game number C is “+1” in step SP65. An effect display is performed based on the indication effect table 60 shown in FIG. 7 based on the number of effect games. Then, in step SP67, it is determined whether or not the number of effect games C is "7". If the number of effect games is not "7", the predictive effect process is terminated, and the process returns to step SP46 in FIG. If the number C is "7", the effect game number C is set to "0" in step SP68, the precursor effect process ends, and the process returns to step SP46.
In step SP61, if the number of effect games C is "0", an effect lottery is performed in step SP62, and it is determined whether or not the effect lottery has been won in step SP63. And returns to step SP46. If the effect lottery has been won, the effect lottery table 50 shown in FIG. 6 is determined based on N + 1 since “1” has already been subtracted in step SP42 in step SP64. Then, in the same manner as described above, the processing of steps SP65 to SP68 is performed and the effect is displayed.
[0075]
In this way, when the indication effect process shown in step SP45 of FIG. 18 is performed, it is determined in step SP46 whether or not the cherry is won, and if the cherry is won, the drawing control of the cherry symbol is performed in step SP47. In step SP48, a cancellation lottery is performed with a winning probability of 1/4. In step SP49, it is determined whether or not a win is made, and in step SP50, the flag G is set to "0". If it is determined in step SP49 that the winning is not achieved, the subroutine of the RT game is terminated.
[0076]
In step SP46 described above, if the cherry is not won, it is determined in step SP51 whether or not the BB flag is won. If the BB flag is won, the count value S of the BB flag stock number is incremented by "+1" in step SP52. Then, in step SP53, the slip pattern is controlled to be pulled in, and the subroutine of the RT game is ended. If it is determined in step SP51 that the BB flag has not been won, it is determined in step SP54 whether or not the RP flag has been won. If it is determined that the RP flag has been won, in step SP55, the drawing lottery of the RP symbol is performed. Is performed. Then, in step SP56, it is determined whether or not a winning is achieved. If the winning is not achieved, in step SP53, the lost symbol is controlled to be pulled in, and the RT game subroutine is terminated. If it is determined in step SP56 that the winning has been achieved, RP symbol pull-in control is performed in step SP57.
[0077]
If it is determined in step SP54 that the RP flag has not been won, the other winning symbol pull-in control is performed in step SP58, and then the subroutine of the RT game ends.
