  According to the third aspect of the present invention, there is provided a symbol variation display means having a plurality of symbol display units for variably displaying a plurality of types of symbols according to a predetermined arrangement in the symbol display area, and a game in a state in which a game medium is inserted. When the game start operation means operated by the player to start the game and the game start operation means are operated, an internal winning combination is determined from a plurality of types of combinations including a specific combination and a special combination An internal lottery means for performing an internal lottery to establish an internal winning flag corresponding to the determined internal winning combination, a stop operation means operated by a player in order to stop the symbol fluctuation display by the symbol fluctuation display means, Display control means for drawing a symbol corresponding to the internal winning flag within a predetermined pull-in range and stopping and displaying it in the symbol display area when a stop operation means is operated; The winning determination means for determining whether or not the symbol stopped and displayed in the symbol display area of the symbol variation display means is a predetermined winning symbol, and when the winning determination means determines that the symbol is a winning symbol Profit granting means for granting a profit corresponding to a symbol to the player, and a specific gaming state in which the winning probability of at least one role is increased when the winning determination means determines that the winning symbol corresponds to the specific role Specific game state generating means for generating one specific game state from among a plurality of types of specific game states having different expected values for the number of games played in one specific game state, When it is determined by the winning determination means that the winning symbol corresponds to the special combination, a special gaming state in which the winning probability of the specific combination is increased and the special gaming state is set. Special gaming state generating means for ending the special gaming state when the number of games played in the game reaches a predetermined value, counting means for counting the number of times the specific gaming state has occurred in the special gaming state, It is characterized by comprising game mode changing means for changing the game mode in the specific gaming state to a game mode advantageous to the player when the value counted by the counting unit reaches a predetermined value.

  According to a fourth aspect of the present invention, there is provided an internal winning flag that is established in a game after the special gaming state is ended on condition that a predetermined condition is satisfied in the specific gaming state during the occurrence of the special gaming state. A game means for presenting information for making it easier to satisfy the predetermined condition when the value counted by the counting means reaches a predetermined value. It has a feature in changing to an aspect.

  According to the invention described in claim 1, when it is determined that the winning symbol corresponds to the special combination, a special gaming state in which the winning probability of the specific combination is increased, and the special combination is generated while the special gaming state is generated. If it is determined that the winning symbol is a corresponding winning symbol, a specific gaming state in which the winning probability of at least one combination is increased and a plurality of game media to be paid out in one specific gaming state have different expected values When one specific gaming state is generated from among the specific gaming states of the type and the number of occurrences of the specific gaming state in the special gaming state reaches a predetermined value, the gaming mode in the specific gaming state becomes a gaming mode advantageous to the player change. Then, when the cumulative value of game media paid out in the special game state reaches a predetermined value, the special game state is terminated.

  Accordingly, the player can minimize the cumulative value of the game media to be paid out until the number of occurrences of the specific game state in the special game state reaches a predetermined value, thereby reducing the remaining period in the special game state. It is possible to play in a game mode that is advantageous to the player, so there is a tension as to which of the multiple types of specific game states will occur until the number of occurrences of the specific game state in the special game state reaches a predetermined value. The game can be performed with a sense, and after the number of occurrences of the specific game state in the special game state reaches a predetermined value, the game can be performed in a game mode advantageous to the player.

  According to the invention described in claim 2, when it is determined that the winning symbol corresponds to the special combination, a special gaming state in which the winning probability of the specific combination is increased and the special combination is generated while the special gaming state is generated. When it is determined that the winning symbol is a corresponding winning symbol, a specific gaming state that increases the winning probability of at least one combination is generated, and is inserted from an expected value of a gaming medium to be paid out in one specific gaming state. When a specific game state is generated from a plurality of types of specific game states having different values obtained by subtracting the expected value of the game medium, and the number of occurrences of the specific game state in the special game state reaches a predetermined value, The game mode in the state is changed to a game mode advantageous to the player. When the value obtained by subtracting the inserted game medium from the game medium paid out in the special game state reaches a predetermined value, the special game state is terminated.

  Thereby, the same effect as that described in claim 1 can be obtained, that is, the player is paid out until the number of occurrences of the specific game state in the special game state reaches a predetermined value. By minimizing the value obtained by subtracting the game media inserted from the game media, the remaining period in the special game state can be played in a game mode that is advantageous to the player, so it is specified in the special game state. Until the number of occurrences of the gaming state reaches a predetermined value, it is possible to play the game with tension as to which of a plurality of types of specific gaming states will occur, and a specific gaming state has occurred in the special gaming state After the number of times reaches a predetermined value, it is possible to play a game in a game mode that is advantageous to oneself.

  According to the invention described in claim 3, when it is determined that the winning symbol corresponds to the special combination, a special gaming state in which the winning probability of the specific combination is increased, and the special combination is generated while the special gaming state is generated. If it is determined that the winning symbol is a corresponding winning symbol, a plurality of games that generate a specific gaming state in which the winning probability of at least one combination is increased and the expected values of the number of games played in one specific gaming state are different. When one specific gaming state is generated from among the specific gaming states of the type and the number of occurrences of the specific gaming state in the special gaming state reaches a predetermined value, the gaming mode in the specific gaming state becomes a gaming mode advantageous to the player change. When the number of games played in the special game state reaches a predetermined value, the special game state is terminated.

  Thereby, the same effect as that described in claim 1 can be obtained, that is, the player is performed until the number of times that the specific game state has occurred in the special game state reaches a predetermined value. By minimizing the number of games, it is possible to play in the game mode that is advantageous to me for the remaining period in the special game state, so the number of occurrences of the specific game state in the special game state is a predetermined value. Until reaching the number, the game can be played with tension as to which of the multiple types of specific game state will occur, and after the number of occurrences of the specific game state in the special game state reaches a predetermined value A game can be played in a game mode advantageous to oneself.

  According to the invention described in claim 4, when the number of occurrences of the specific gaming state in the special gaming state reaches a predetermined value, the symbol corresponding to the internal winning flag established in the game after the completion of the special gaming state is notified. It changes to the game mode which presents the information for making it easy to satisfy the conditions to do. Thereby, the player can benefit from being able to easily notify the symbol corresponding to the internal winning flag established in the game after the end of the special gaming state by playing in a game mode advantageous to him. it can.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 schematically shows a front appearance of a slot machine (game machine in the present invention). A display window 2 is provided in front of the slot machine 1, and the player can visually recognize the symbols on the reel 3 (the symbol variation display means in the present invention) provided therein through the display window 2.

  As shown in FIG. 3, the symbols are drawn on the circumferential surfaces of the left reel 3a, the middle reel 3b, and the right reel 3c. When the reels 3a to 3c are stopped, the upper, middle, A symbol is displayed corresponding to the lower row. The display window 2 is provided with a total of five winning lines (three horizontal lines corresponding to the upper, middle, and lower stages and two diagonally arranged) (shown by broken lines in FIG. 1). The active line display section 4 for displaying the activated pay line is provided on the side of the, and a corresponding win is generated when the winning symbols are aligned on any of the pay lines.

  Above the display window 2, a liquid crystal display unit 5 (notifying means in the present invention) for displaying various information such as a payout progress state of medals during the bonus game, a lamp unit 6 composed of various lamps, and various effects. A speaker 7 for outputting sound or the like is provided. Below the display window 2 are provided a MAXBET button 8 for inserting a credit medal, a credit settlement button 9 for settlement of a credit medal, and a medal insertion slot 10 for inserting a medal. (Game start operation means in the present invention), left stop button 12 (stop operation means in the present invention), middle stop button 13 (stop operation means in the present invention), right stop button 14 (stop operation in the present invention) Means). On the right side of the display window 2, a payout number display unit 15 for displaying the number of payout medals and a credit display unit 16 for displaying the number of credit medals are provided. Further, a medal payout port 17 through which medals are paid out and a tray 18 for receiving medals paid out from the medal payout port 17 are provided at the bottom front of the slot machine 1.

  When the slot machine 1 operates the start lever 11 in a series of game start operations, that is, in a state where the player has inserted a medal into the medal insertion slot 10 or a credit medal is inserted by operating the MAXBET button 8, the internal lottery is performed. At the same time, the reels 3a to 3c are started (rotation operation is started). And after starting each reel 3a-3c, the slot machine 1 stops each reel 3a-3c according to operation of each stop button 12-14, and complete | finishes 1 game. If the result of the internal lottery is winning, an internal winning flag (big bonus (BB) combination flag, regular bonus (RB) combination flag, small combination flag, corresponding to the internal winning combination won by the internal lottery, Replay flag) is set to “1” (established), and stop control including so-called slip control (retraction control) based on the internal winning flag (the reels 3a to 3c are selected according to the type of the internal winning flag) Alternatively, control is performed to stop at the lost symbol), and the number of medals corresponding to the winning symbol is paid out from the medal payout opening 17. The pull-in control is a control capable of drawing and stopping up to four symbols on the winning line from when the operation of each of the stop buttons 12 to 14 is detected.

  As the winning symbols, a BB role symbol, an RB role symbol, a small role symbol, and a replay symbol are set as shown in FIG. In this case, as the RB role symbol, two types of the first RB role symbol and the second RB role symbol are set, and as the small role symbol, a plum symbol, a bell symbol, a watermelon symbol, a red cherry symbol, Six types of blue cherry design and green cherry design are set. The BB combination is a special combination in the present invention, and the RB combination is a specific combination in the present invention.

  The slot machine 1 sets the winning probabilities of the above-mentioned BB role and RB role in a plurality of levels (for example, 6 levels from 1 to 6) by a specific employee operating the setting means with the front door opened. The larger the numerical value (setting value), the larger the winning probability of the BB combination and the RB combination is set. The winning probabilities of the small role and the replay role other than the BB role and the RB role are not different depending on the set value, and the winning probability common to all the set values is set. Note that the small combination and the replay combination may be set in a plurality of stages, like the BB combination and the RB combination.

  FIG. 2 is a functional block diagram showing the electrical configuration of the slot machine 1 described above. The control unit 19 (internal lottery means, display control means, winning determination means, profit granting means, specific gaming state generating means, special gaming state generating means, counting means, gaming mode changing means in the present invention) is a CPU, ROM, The microcomputer includes a RAM, an I / O, and the like. Each operation signal is output from the start lever 11, the left stop button 12, the middle stop button 13, the right stop button 14, the MAXBET button 8, and the credit check button 9. Enter.

  In addition, the control unit 19 inputs an inserted medal detection signal from the inserted medal detection unit 20 that determines the authenticity and quantity of medals inserted into the medal insertion slot 10, and inputs a setting signal from the set value operation unit 21. Further, the control unit 19 detects the passage of a reel driving unit 23 that drives each of the reel motors 22a to 22c corresponding to each of the reels 3a to 3c and a reference position piece provided on each of the reels 3a to 3c. A reference position detection unit 25 for detecting a reference position based on detection signals from the sensors 24a to 24c, a medal payout unit 26 for paying out medals from the medal payout port 17, the above-described effective line display unit 4, a payout number display unit 15, A credit display unit 16 is connected.

  Further, the control unit 19 is connected to a display control unit 27, a sound output control unit 28, and a lamp control unit 29. The display control unit 27 controls various display operations in the liquid crystal display unit 5 described above. The sound output control unit 28 controls various sound output operations from the speaker 20 described above. The lamp control unit 29 controls various lighting operations and blinking operations in the lamp unit 6 described above.

  In this case, the control part 19 is based on each input signal and the control program memorize | stored in ROM, the reel drive part 23, the medal payout part 26, the effective line display part 4, the payout number display part 15, and the credit display part 16 In addition to controlling the operations of the display control unit 27, the sound output control unit 28, and the lamp control unit 29, an out signal (1 pulse output for every medal insertion or 1 credit medal bet) and a safe signal (for 1 medal) 1 pulse output for each payout or 1 credit medal payout), game signal (1 pulse output for each game start), BB signal (level signal output during BB game), RB signal (level signal output during RB game) ) Generation.

  In the configuration described above, the control unit 19 holds an internal winning combination lottery table for determining an internal winning combination for each of the base game, the replay time (RT), the BB game, and the RB game. FIG. 5 shows an example of the internal winning combination lottery table when the set value is set to “1”, for example. In the internal lottery performed when the game is started, one random number is obtained from the random numbers generated in the range of 0 to 65535, and the obtained random number is compared with the random number in the internal winning combination lottery table described above. To determine the internal winning combination. That is, the winning probability of each combination is a value obtained by dividing the number of selected random numbers by the total number of random numbers (65536).

  In the present embodiment, an internal lottery of the first RB combination and the second RB combination is performed in the BB game. When the first RB combination is won in the BB game, the first RB game is generated, and the first RB game is ended on condition that 12 games, 2 wins or the BB game is ended. On the other hand, when the second RB combination is won in the BB game, the second RB game is generated, and the second RB game is ended on condition that 12 games, 8 wins or the BB game is ended. Note that the winning probability of the first RB combination and the winning probability of the second RB combination in the BB game are set to be equal. Also, the BB game is ended when the number of medals paid out reaches a predetermined number (for example, 360). Note that the BB game is a special game state in the present invention, and the first RB game and the second RB game are in a specific game state in the present invention.

  In each RB game, a selection game is played for each game. In the selected game, the player is made to operate the player in anticipation of the pressing order of the stop buttons 12 to 14. In the selected game, when the game start operation is performed, the correct stop buttons 12 to 14 are pressed. The order (six patterns) is determined by lottery, and the correct answer is given when the determined pressing order matches the pressing order actually operated by the player. Each time a correct answer is made, an assist time (AT) counter is incremented by 1 and accumulated. If the AT counter is 1 or more after the BB game is over, an AT is generated. Here, in the selection game, the third (previous) RB game after the occurrence of the BB game is a disadvantageous game for the player, and the fourth (subsequent) RB after the occurrence of the BB game. The game is an advantageous game for the player (an advantageous game mode in the present invention), and the RB game up to the third time after the occurrence of the BB game and the RB game from the fourth time perform different effects.

  The RB game up to the third time after the occurrence of the BB game, which is a disadvantageous game for the player, is a 6-option game. That is, in the 6-option game, as shown in FIG. 6, when a game start operation is performed, “? Marks” are placed at all positions (three positions) corresponding to the arrangement of the stop buttons 12 to 14. Display and let the player predict the pressing order for all three stop buttons 12-14. When the player operates one of the stop buttons, if the push order determined by the lottery matches the push order actually operated by the player, the “smile mark” is displayed and the first push order matches. If the second pressing order also matches, it means that the six-choice game has been correctly answered, so the “GOOD! Mark” is displayed, the six-choice game is terminated, and the AT counter is incremented by one. On the other hand, if the pushing order determined by the lottery does not match the pushing order actually operated by the player, the “MISS! Mark” is displayed, the 6-option game is terminated, and the AT counter is not incremented by 1. . The probability that the player will correctly answer the 6-option game is (1/3) × (1/2) = 1/6.

  In FIG. 6, the push order determined by the lottery is “left stop button”, “right stop button”, “middle stop button”, and the push order actually operated by the player is “left stop button”, “middle stop button”. The case of “button” is shown as an example. In this case, the 6-option game is incorrect when the player operates the “medium stop button”.

  The RB game from the fourth time after the occurrence of the BB game, which is an advantageous game for the player, is a two-choice game. That is, in the two-choice game, as shown in FIG. 7, when the game start operation is performed, “1 mark” (first operation is performed at one position corresponding to the arrangement mode of the stop buttons 12 to 14. And a “? Mark” is displayed at the remaining two positions to allow the player to predict the pressing order of the two stop buttons 12-14. Also in this case, if the player operates one of the stop buttons, if the pressing order determined by the lottery matches the pressing order actually operated by the player, the “smile mark” is displayed and the first pressing is performed. If the order matches and the second pressing order matches, then the two-choice game has been correctly answered, so the “GOOD! Mark” is displayed, the two-choice game is terminated, and the AT counter is incremented by one. On the other hand, if the pushing order determined by the lottery does not match the pushing order actually operated by the player, the “MISS! Mark” is displayed, the two-choice game is terminated, and the AT counter is not incremented by one. . The probability that the player will correctly answer the two-choice game is ½.

  In FIG. 7, the push order determined by the lottery is “left stop button”, “right stop button”, and “middle stop button”, and the push order actually operated by the player is “left stop button”, “right stop button” The case of “button” is shown as an example. In this case, the two-choice game becomes a correct answer when the player operates the “right stop button”.

  That is, in this embodiment, every time the selected game is answered correctly, the AT counter is incremented by 1. Therefore, it is a concern for the player to digest the RB game as much as possible with the two-choice game. Therefore, the player expects to win the first RB game that can be finished in a short period of time among the first RB game and the second RB game in the third RB game which is a disadvantageous game for him. Will do.

  On the left reel 3a, symbols corresponding to red cherry, blue cherry, and green cherry are arranged at intervals of six symbols. In other words, when any of the cherries is won internally, the symbols are arranged so as to win the cherries with a probability of 1/3 unless the type of the cherries won internally is notified. When these winning combinations are won internally in the normal game, if the AT counter at that time is 1 or more, the cherry symbol which is the winning combination is displayed on the liquid crystal display unit 5 to notify the player, and the AT counter 1 is subtracted. When the BB game is finished, RT is generated, and when winning the internal winning cherry, RT is finished.

  That is, if any of the cherries is won internally during RT after the BB game is finished, if the AT counter at that time is 1 or more, the cherry symbol that is the winning combination is displayed on the liquid crystal display unit 5. Since it is displayed and informed to the player, the player can grasp that the winning combination is a cherry, and the RT is terminated by avoiding the winning of the internally winning cherry. It becomes possible to continue playing without any problems.

  Next, the operation of the above configuration will be described with reference to FIGS. The control unit 19 periodically performs a game start process and a winning process. Hereinafter, the game start process and the winning process will be sequentially described.

(1) Game Start Process When the game start process is started, the control unit 19 determines whether or not an operation for starting a game (operation of the start lever 11) has been detected (S1). Here, when the control unit 19 determines that the game start operation is detected by operating the start lever 11 in order to start the game (S1: YES), the control unit 19 has a decimal number of 0 to 65535. One random number is acquired from the random numbers generated in the range (S2), the acquired random number is compared with the random number in the internal winning combination lottery table shown in FIG. 5 (S3), and the internal winning flag of the internal winning combination Is set to "1" (S4).

Next, the control unit 19 determines whether or not the BB game flag is set to “0” (S5), and determines that the BB game flag is set to “0” (S5: YES). It is determined whether or not the cherry flag is set to “1” (S6). If it is determined that the cherry flag is set to “1” (S6: YES), whether or not the AT counter is 1 or more. If it is determined that the AT counter is 1 or more (S7: YES), the symbol of the winning combination is displayed on the liquid crystal display unit 5 (S8), and the AT counter is decremented by 1 (S7). S9) The rotation of the reels 3a to 3c is started (S10), the game start process is terminated, and the process returns.
That is, when any cherry is won internally after the BB game is finished, if the AT counter at that time is 1 or more, the symbol of the internally won cherry is displayed on the liquid crystal display unit 5 to notify the player. Will do. The above-described S6 to S9 are effects at the time of AT.

  Further, when determining that the BB game flag is not set to “0” (S5: NO), the control unit 19 determines whether or not the RB game flag is set to “1” (S11). If it is determined that the RB game flag is set to “1” (S11: YES), it is determined whether the bell flag is set to “1” (S12), and the bell flag is set to “1”. If it is determined (S12: YES), it is determined whether or not the 2-option game flag is set to “0” (S13).

  If the control unit 19 determines that the 2-option game flag is set to “0” (S13: YES), the control section 19 performs a 6-option game effect (S14), while the 2-option game flag is set to “ If it is determined that it is not set to “0” (S13: NO), a two-option game effect is performed (S15). And the control part 19 starts rotation of the reels 3a-3c (S10), complete | finishes a game start process, and returns. The above-described S12 to S15 are selection games.

(2) Winning process When the winning process is started, the control unit 19 determines whether or not a reel stop operation has been detected (S21). Here, when the control unit 19 determines that the reel stop operation is detected by operating the stop buttons 12 to 14 to stop the reels 3a to 3c (S21: YES), the control unit 19 responds. The rotation of the reels 3a to 3c is stopped (S22). Then, the control unit 19 determines whether or not the rotation of all the reels 3a to 3c is stopped (S23), and determines that the rotation of all the reels 3a to 3c is stopped (S23: YES). It is determined which winning symbol the stop symbol is (S24), and which winning combination is determined (S25 to S29).

  When the control unit 19 determines that the winning symbol is a replay symbol and has won the replay (S25: YES), the control unit 19 sets a replay game (S30) and sets the replay flag to “0” (S31). ). Next, the control unit 19 determines whether or not the selected game has been achieved by determining whether or not the player has correctly answered the 6-option game or the 2-option game (S32). If it is determined that the selected game is achieved by correctly answering the two-choice game (S32: YES), the AT counter is incremented by 1 (S33). Note that if the control unit 19 determines that the selected game has not been achieved because the player has not correctly answered the 6-option game or the 2-option game (S32: NO), the control unit 19 does not increment the AT counter by 1. .

  Next, the control unit 19 determines whether or not the BB game end condition has been achieved (S34). If the control unit 19 determines that the BB game end condition has been achieved (S34: YES), the control unit 19 sets the BB game flag to “0”. (S35), the RT flag is set to "1" (S36), and RT is started. Then, the control unit 19 sets the RB game flag to “0” (S37), resets the RB counter (S38), sets the 2-option game flag to “0” (S39), and ends the winning process. And return. Further, when determining that the BB game end condition has not been achieved (S34: NO), the control unit 19 determines whether or not the RB game end condition has been achieved (S40), and the RB game end condition is determined. In this case, the RB game flag is set to “0” (S37), the RB counter is reset (S38), and the 2-option game flag is set to “0”. (S39), the winning process is terminated and the process returns.

  Further, when the control unit 19 determines that the winning symbol is the BB role symbol and has won the BB role (S26: YES), the control unit 19 sets the BB game flag to “1” (S41), and sets the BB role flag to “ "0" is set (S42), steps S32 to S40 described above are performed, the winning process is terminated, and the process returns.

  When the control unit 19 determines that the winning symbol is either the first RB role symbol or the second RB role symbol and has won either the first RB role or the second RB role (S27: YES), the RB game The number of RB games consumed in the BB game by setting the flag to “1” (S43), setting the RB combination flag to “0” (S44), and determining whether the RB counter is 3 or less It is determined whether or not is 3 times or less (S45). When the control unit 19 determines that the RB counter is 3 or less (S45: YES), the control unit 19 adds 1 to the RB counter (S46), performs the above steps S32 to S40, and ends the winning process. Return. On the other hand, when the control unit 19 determines that the RB counter is not 3 or less (S45: NO), the 2-option game flag is set to “1” (S47), and the above-described steps S32 to S40 are performed, and the winning process is performed. Exit and return.

  In other words, the player will play a 6-choice game that is disadvantageous to him (difficult to acquire an AT counter) in the RB game up to the third time after the BB game is generated, while the BB game is generated. Then, in the fourth RB game, a two-choice game that is advantageous to the player (easy to acquire an AT counter) is performed.

  Further, when the control unit 19 determines that the winning symbol is any one of the red cherry symbol, the blue cherry symbol, and the green cherry symbol, and has won any one of the red cherry, the blue cherry, and the green cherry (S28: YES). Then, it is determined whether or not the BB game flag is set to “0” (S48). When it is determined that the BB game flag is set to “0” (S48: YES), the RT flag is set to “0”. (S49), and RT is terminated. Then, the control unit 19 performs a payout process for paying out the number of medals corresponding to the winning small combination from the medal payout opening 17 (S50), sets the small combination flag to “0” (S51), and the above-described steps. S32 to S40 are performed, the winning process is terminated, and the process returns.

  In addition, when the control unit 19 determines that the winning symbol is another small role symbol and has won another small role (S29: YES), in this case as well, the number of medals corresponding to the winning small role are selected. A payout process for paying out from the medal payout opening 17 is performed (S50), the small role flag is set to “0” (S51), the above steps S32 to S40 are performed, the winning process is terminated, and the process returns.

  FIG. 11 shows three RB games that are disadvantageous to the player by winning the first RB role first after winning the BB role, then winning the first RB role, and then winning the second RB role. As an example, the game is digested with two first RB games and one second RB game, and then the fourth and subsequent RB games advantageous to the player are digested.

  By the way, the above has described a configuration in which the number of medals paid out is adopted as the BB game end condition, and the BB game is ended when the number of medals paid out reaches a predetermined number (for example, 360). Other conditions may be adopted as the BB game end condition, and when the difference number obtained by subtracting the number of inserted medals from the number of paid out medals reaches a predetermined number (for example, 350), the BB game The BB game may be ended when the number of played games reaches a predetermined number (for example, 30 times). However, if the configuration is such that the BB game is terminated when the difference number reaches the predetermined number, a plurality of types of RB games having different expected values for the difference number from the start to the end of one RB game are set. If the number of played games reaches a predetermined number, the BB game is terminated, and a plurality of different expected values of the number of games required from the start to the end of one RB game are different. It is necessary to set a type of RB game.

  As described above, according to the present embodiment, in the slot machine 1, the 6-option game, which is a disadvantageous game for the player, is performed as the third RB game after the BB game is generated, and the BB game is generated. Since the second choice game, which is a game advantageous to the player, is performed as the fourth RB game after that, the player is paid out in the third RB game after the BB game is generated. By minimizing the number of medals, it becomes possible to play the remaining period in the BB game in a game mode advantageous to oneself, and the RB game up to the third RB game after the occurrence of the BB game ends. A game can be played with a sense of tension as to whether a first RB game or a second RB game occurs under different conditions, and a BB game is generated In the RB game from the fourth time since it is possible to perform the game in an advantageous game mode for me.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
The present invention may be applied to a slot machine using parrots, game balls, or a so-called enclosing slot machine that does not use actual medals.
In the RB game which is disadvantageous to the player, the selection game may not be performed.
There may be three or more types of RB games.
The RB combination and the RB game are not in a one-to-one relationship, and the type of RB game generated when the RB combination wins, the RB end condition, and the like may be determined by lottery.
The number of RBs until a game advantageous to the player is generated may not be three. Further, the number of RBs until a game advantageous to the player is generated may be determined by a lottery instead of a fixed number, and the player may be notified of the number of times determined by the lottery. It is not necessary to notify.
As a mode of the game that is advantageous to the player, other modes such as increasing the winning probability of a small role, increasing the number of payouts at the time of winning a prize, or performing an effect capable of discriminating a set value may be used.
