Abstract

PROBLEM TO BE SOLVED: To provide a game machine to which a new interest is added by changing a game state after a bonus mode terminates according to the content of progress of a bonus mode without impairing the original interest of the bonus mode that allows the bonus game to be played repeatedly.SOLUTION: When termination conditions for a regular bonus game are satisfied before a big bonus game terminates, the game state, in response to the satisfaction of the termination conditions, shifts from an RT2 state to an RT3 state having a high probability of drawing a replay prize symbol combination prize in a prize symbol combination lottery than the RT2 state. When the game state shifted from the RT2 state to the RT3 state, the RT3 states continues even after the big bonus game terminates. While, when the big bonus game terminates without the termination conditions of the regular bonus game being satisfied, the game state remains unchanged, with the RT2 state, which is a game state until then, continuing even after the big bonus game terminates.

Description

  The present invention relates to a gaming machine such as a slot machine.

  For example, in a slot machine, when a start lever is operated after a medal is inserted or a bet is operated by a bet button, three reels each having a plurality of types of symbols arranged on the circumferential surface start to rotate all at once. . In addition, a plurality of winning combinations are set, and a lottery (internal lottery) relating to the winning combinations is performed when the start lever is operated. Thereafter, when a reel stop button provided corresponding to each reel is operated, the reel corresponding to the operated reel stop button stops. When all reels stop, one game is over. When a combination of symbols corresponding to any combination is arranged on the winning line when all the reels are stopped, the winning combination of the combination is won.

  The role includes a small role in which a predetermined number of medals are paid out for winning, a replay role in which execution of one game is allowed without winning a medal for winning, and a right to execute a big bonus game (RBB game). Includes big bonuses to be granted. When winning the big bonus role, the big bonus game is started. In the big bonus game, there is a regular bonus game (RB game) in which at least one of the winning of a small role or the completion of a predetermined number of games is completed as a termination condition until the total number of medals to be paid out exceeds a predetermined upper limit number. It is executed repeatedly. Therefore, in the big bonus game, the player can acquire a large number of medals.

  In the slot machine, a normal state and a replay high-accuracy state are set as game states. In the replay high-accuracy state, the winning probability of the replay role is increased as compared with the normal state, and the probability that a difference is generated in the lottery is reduced. Therefore, in the replay high probability state, the player can obtain a medal by winning a small role without reducing the number of medals owned (the number of possessions).

  In the conventional typical slot machine, the progress of the big bonus game is irrelevant to the game state after the end of the big bonus game. If the game state after the end of the big bonus game can be changed according to the progress of the big bonus game, new game characteristics can be provided.

  Therefore, in response to winning the regular bonus role during the big bonus game, the game state is replayed from the normal state with high accuracy. Before the regular bonus combination wins (before the symbol combination corresponding to the regular bonus combination is lined up on the winning line), the total payout number of medals reaches the predetermined upper limit and the big bonus game A configuration has been proposed in which the game state after the end of the big bonus game is maintained in the replay high probability state when the end condition is satisfied.

Japanese Patent No. 4440322

  However, the big bonus game is interesting in executing the regular bonus game, and the above-described configuration lacks the fun of the big bonus game.

  The object of the present invention is to provide a new interest by changing the game state after the end of the bonus mode according to the progress of the bonus mode without losing the original interest of the bonus mode in which the bonus game can be repeatedly executed. It is to provide a gaming machine to which is added.

  In order to achieve the above object, a gaming machine according to the present invention has a plurality of symbol arrangements, a plurality of symbol display means for variably displaying and stopping the symbols, and a predetermined permission for executing one game. After the condition is satisfied, a start instructing unit operated to instruct the start of symbol variation display by the plurality of symbol display units, and a symbol by the symbol display unit provided corresponding to each of the symbol display units A combination of a plurality of stop instructing means pushed to instruct to stop the change display and a predetermined combination of small role symbols for each game is stopped and displayed by the plurality of symbol displaying means, and a winning is achieved. A lottery means for executing a lottery for drawing at least a small combination for which a predetermined number of game media are paid out for the winning, a normal mode, and a predetermined number of small combination winnings or Mode execution means for selectively executing a bonus mode capable of continuously executing a bonus game whose completion condition is completion of at least one of the fixed number of games until the total number of game media payout exceeds a predetermined upper limit number; And a game state transition means for shifting the game state between at least the normal game state and the first special game state that is more advantageous to the player than the normal game state. The lottery object in the normal mode includes a bonus combination to which the right to enter the bonus mode is granted. The game state transition means changes the game state from the normal game state to the first game state in response to the completion of the bonus game in the normal game state after entering the bonus mode. Transition to the special game state.

  This gaming machine is provided with a plurality of symbol display means. Each symbol display means has an array of a plurality of types of symbols, and these symbols are variably displayed and stopped. The gaming machine further includes a start instruction unit and a stop instruction unit. When the start instructing unit is operated after the predetermined condition is established, the symbol variation display by each symbol display unit is started. The stop instructing means is provided corresponding to each symbol display means. When the stop instructing means is operated after the symbol variation display is started, the symbol displaying means corresponding to the operated stop instructing means. The change display of the symbol is stopped (the symbol is stopped). When all stop instruction means are operated, one game is finished.

  In this gaming machine, the normal mode and the bonus mode are selectively executed.

  In the normal mode, a lottery for at least a small combination and a bonus combination is executed for each game. A small combination is a combination in which a combination of predetermined small combination symbols is stopped and displayed by a plurality of symbol display means to win a prize, and a predetermined number of game media are paid out for the winning. The bonus combination is a combination to which a right to enter the bonus mode is given. When the bonus combination is won by lottery in the normal mode and the bonus combination is won (when the symbol combination corresponding to the bonus combination is stopped and displayed by the symbol display means), the bonus mode is entered.

  In the bonus mode, a bonus game in which at least one of winning of a small role or at least one of a predetermined number of games is completed is continuously executed until the total payout amount of game media exceeds a predetermined upper limit number. be able to.

  In this gaming machine, the game state after the transition from the bonus mode to the normal mode differs depending on the progress of the bonus mode. That is, if the bonus game end condition is achieved before the bonus mode ends, if the previous game state is the normal game state, the game state is set to the normal game state in response to the completion of the end condition. To the first special game state which is more advantageous to the player than the normal game state. And even after shifting to the normal mode, the first special game state continues. On the other hand, if the bonus mode is terminated without achieving the bonus game termination condition, the game state does not change, and the game state up to that point continues even after the transition from the bonus mode to the normal mode.

  For this reason, during the bonus mode, while giving the player a sense of expectation that the game state after the end of the bonus mode will be the first special game state, that is, a sense of expectation for achieving the bonus game termination condition, Can be entertained. As a result, it is possible to add a new interest by changing the game state after the end of the bonus mode according to the progress of the bonus mode without losing the original fun of the bonus mode that can be executed repeatedly the bonus game Can do.

  The lottery target includes a replay combination in which a combination of predetermined replay symbols is stopped and displayed by a plurality of symbol display means, and a winning combination is allowed and execution of one game is permitted without satisfying a predetermined condition. It may be. The normal game state is a state in which the winning probability of the replay role in the lottery by the lottery means is relatively low, and the first special game state is a state in which the winning probability of the replay role in the lottery by the lottery means is relatively high. There may be.

  In this case, since the replay role is won with high probability in the first special game state, the player acquires the game media by winning the small role without reducing the number of game media owned (the number of possessions). be able to.

  In the normal game state, a winning combination is obtained when a predetermined combination of normal replay symbols is stopped and displayed on a lottery object by a plurality of symbol display means, and execution of one game is permitted without satisfying a predetermined condition for the winning. The first special game state is a state in which a normal replay combination is included, and a combination of predetermined chance replay symbols is stopped and displayed on a lottery object by a plurality of symbol display means. A state in which execution of one game is permitted without satisfying the condition and a chance replay combination that triggers the transition of the game state may be included. Then, in response to the winning of the chance replay role, the game state is in the second special game state in which the normal replay role is included in the lottery object and the winning probability of the normal replay role in the lottery is higher than the normal game state. May be migrated.

  During the bonus mode, the winning probability of the small part in the lottery may be higher than the winning probability of the small part in the lottery in the normal mode.

  Further, during the bonus mode, the winning probability of the small role in the lottery in the first special game state may be the same as the winning probability of the small role in the lottery in the normal game state.

  The game state may be changed from the first special game state to the normal game state in response to the winning of the bonus combination in the first special game state, or the first special game state is a bonus. Even if the winning combination is won, the game state may be maintained without shifting from the first special game state.

  In the latter case, that is, even when a bonus combination is won in the lottery in the first special game state, if the game state is maintained without shifting from the first special game state, there are a plurality of combinations of predetermined falling symbols. In response to the stop display by the symbol display means, the game state may be shifted from the first special game state to the normal game state.

  According to the present invention, there is a new interest by changing the game state after the end of the bonus mode according to the progress of the bonus mode without impairing the original interest of the bonus mode in which the bonus game can be repeatedly executed. Can be added.

Each time a medal is discharged to the tray 21 by the medal discharge motor 54, a detection signal is output from the medal discharge sensor 56, and the detection signal is input to the CPU 41 via the input / output port 44.

  The number of medals (credits) deposited in the slot machine 1 is counted by a counter provided in the RAM 43. The CPU 41 controls the medal block solenoid 53 until the number of credits reaches 50, the discharge destination of medals inserted from the medal insertion slot 14 is the medal storage unit, and when the number of credits reaches 50, the discharge destination Is used as a saucer 21. Further, after the number of credits reaches 50, when a medal payout (payout) is won, the CPU 41 controls the medal discharge motor 54 to discharge the payout medal to the tray 21.

  The ROM 42 stores a plurality of lottery tables 57 in addition to the control program. For each game, the CPU 41 uses a single lottery table 57 to perform a lottery (internal lottery) in which a plurality of types of combinations and outliers are subject to lottery.

  The roles include a replay role, first to third bell roles, a watermelon role, a cherry role, and a big bonus (RBB) role.

  When a replay combination is won, a combination of symbols “Replay”-“Replay”-“Replay” is allowed to line up on the winning line. When the combination of symbols “Replay”-“Replay”-“Replay” is arranged on the winning line, the player is awarded a replay role, and one game is permitted to be executed without any medal bet.

  The first to third bell roles are so-called push order small roles. When winning the first to third bell roles, a combination of symbols “Bell”-“Bell”-“Bell” and a predetermined symbol combination composed of “Bell 1” symbol and “Bell 2” symbol One of them is allowed to line up on the winning line. When the pressing order of the left stop button 19L, the middle stop button 19C and the right stop button 19R matches a predetermined correct answer pressing order, and a combination of symbols “bell”-“bell”-“bell” is arranged on the winning line, A win for the bell role (winning in the correct push order) and a relatively large number (for example, 8) of medals are paid out. In addition, the left stop button 19L, the middle stop button 19C, and the right stop button 19R are pressed in an order different from the correct answer pressing order, and a predetermined symbol combination different from “bell”-“bell”-“bell” (“bell” If the combination of the “1” symbol and the “Bell 2” symbol) is placed on the winning line, it will be awarded to a small role different from the bell role (winning in the wrong order). A relatively small number (for example, one) of medals is paid out.

  The watermelon role is a small role. When winning the watermelon role, it is allowed that a combination of symbols of “watermelon”-“watermelon”-“watermelon” is arranged on the winning line. When a combination of symbols of “watermelon”-“watermelon”-“watermelon” is arranged on the winning line, the player becomes a watermelon and a predetermined number (for example, 12) of medals are paid out for the winning. .

  The role of cherry is a small role. When winning the cherry role, the combination of symbols including the “cherry” symbol is allowed to stop on the winning line. When a combination of symbols including the “cherry” symbol is arranged on the winning line, the player wins the cherry role, and a predetermined number (for example, four) of medals is paid out for the winning.

  When the big bonus combination is won, it is allowed that a combination of symbols “Red 7”-“Red 7”-“Red 7” is arranged on the winning line. When the combination of symbols “Red 7”-“Red 7”-“Red 7” is arranged on the winning line, the player wins a big bonus combination and a big bonus game (RBB game) is started. In the big bonus game, for example, a regular bonus game (RB game) is repeated with a winning condition of at least one of eight small roles or the completion of eight games as an end condition until the total payout number of medals exceeds 50. Can be executed.

  Note that during execution of the big bonus game is an example of the bonus mode, and during non-execution of the big bonus game is an example of the normal mode.

  The effect control board 32 includes a CPU 61, a ROM 62, a RAM 63, a signal input circuit 64, and a drive circuit 65. The CPU 61 is connected to the ROM 62, RAM 63, signal input circuit 64, and drive circuit 65. The CPU 61 controls the display of the liquid crystal display 22 via the drive circuit 65 based on a signal input from the signal input circuit 64 in accordance with a control program stored in the ROM 62. At this time, the RAM 63 is used as a work area.

<1 game flow in a slot machine>

  FIG. 3 is a flowchart showing a flow of game control executed on the main control board.

  On the main control board 31, the CPU 41 repeatedly executes the game control shown in FIG.

  Prior to the start of the game, the presence / absence of an operation signal input from the MAX bet button 15, the 1-sheet bet button 16 and the 2-sheet bet button 17 and the presence / absence of a detection signal input from the medal insertion sensor 55 are repeatedly examined ( Step S1).

  If any operation signal or detection signal is input, it is determined that a medal is bet (YES in step S1), and it is checked whether or not an operation signal is input from the start lever 18 (step S2). If no operation signal is input from the start lever 18 (NO in step S2), whether or not the operation signal is input from the MAX bet button 15, the 1-bet button 16 and the 2-bet button 17 and the medal insertion sensor 55 The presence / absence of the detection signal is checked again (step S1).

  When an operation signal from the start lever 18 is input, that is, when the start lever 18 is operated (YES in step S2), the medal block solenoid 53 is controlled to discharge the medal to be inserted from the medal insertion slot 14. Is placed in the tray 21 and subsequent insertion of medals is prohibited (step S3).

  Further, when the start lever 18 is operated, one lottery table 57 is read from the ROM 62, and a winning lottery is performed (step S4). In the role lottery, a random number value is acquired from a random number counter in response to the start lever 18 being operated. Then, one of the lottery tables stored in the ROM 42 is referred to, and based on the random number value and the lottery table 57, the winning combination or losing is determined.

  The selection of the lottery table 57 used for the role lottery will be described in detail later.

  Thereafter, a drive pulse signal is supplied to the stepping motors 51L, 51C, 51R, and rotation of the reels 4L, 4C, 4R is started (step S5). When the rotation speed of the reels 4L, 4C, 4R becomes constant, operation signals from the left stop button 19L, the middle stop button 19C, and the right stop button 19R can be received.

  Thereafter, it is repeatedly checked whether or not the left stop button 19L, middle stop button 19C and right stop button 19R are operated (step S6).

When the left stop button 19L, middle stop button 19C, and right stop button 19R are selectively operated (YES in step S6), the supply of drive pulse signals to the stepping motors 51L, 51C, 51R is stopped. Thereby, the rotation of the reels 4L, 4C, 4R is stopped (step S7). The timing for stopping the supply of the drive pulse signal to the stepping motors 51L, 51C, 51R is controlled based on the timing when the left stop button 19L, the middle stop button 19C and the right stop button 19R are operated, and the result of the lottery drawing. The

  When the rotation of all the reels 4L, 4C, 4R is stopped (YES in step S8), it is determined whether or not the combination of symbols corresponding to the winning combination is arranged on the activated winning line, and the winning line is displayed. If a combination of symbols corresponding to the winning combination is lined up, it is determined that the winning combination is won (step S9).

  Thereafter, if the number of credits has not reached 50, the medal block solenoid 53 is controlled so that the discharge destination of medals inserted from the medal insertion slot 14 is set as the medal storage section, and the insertion of medals from the medal insertion slot 14 is performed. Allowed (step S10).

Thus, the game control ends. One game in the slot machine 1 is from betting a medal to the end of the game control.

  FIG. 4 is a view showing game state transitions in the slot machine according to the first embodiment. 5, 6, 7, 8, 9, and 10 are examples of lottery tables.

  In the slot machine 1, there are an RT0 state, an RT1 state, an RT2 state, and an RT3 state as game states.

  Immediately after the slot machine 1 is powered on, the game state is the RT0 state (initial state).

  In the role lottery in the RT0 state, the lottery table 57 for RT0 is used. In the lottery table 57 for RT0, as shown in FIG. 5, 8978 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay combination in the combination lottery in the RT0 state is about 1 / 7.3. In addition, 7000 random numbers are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. The winning probabilities of the first to third bell roles in the role lottery in the RT0 state are about 1 / 9.362 (≈9.4), respectively. As the winning values for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probabilities for the watermelon role and the cherry role in the role lottery in the RT0 state are about 1 / 109.2, respectively. As the winning value of the big bonus combination, 200 random numbers are set, and the winning probability of the big bonus combination in the combination lottery in the RT0 state is about 1 / 327.7. In the lottery table 57 for RT0, 34158 random number values are assigned as outliers, and the unfair chance probability (probability of outliers) in the role lottery in the RT0 state is about 1 / 1.9.

  When the big bonus combination is won in the combination lottery in the RT0 state, that is, when the random value obtained from the random number counter matches one of the big bonus combination winning values set in the lottery table 57 for RT0, it is shown in FIG. As shown, the game state shifts from the RT0 state to the RT1 state.

  In the role lottery in the RT1 state, the lottery table 57 for RT1 is used. In the RT1 lottery table 57, as shown in FIG. 6, 8979 random values out of 65536 random numbers generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay combination in the combination lottery in the RT1 state is about 1 / 7.3. In addition, 7000 random numbers are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. The winning probabilities of the first to third bell roles in the role lottery in the RT1 state are about 1 / 9.362 (≈9.4), respectively. As the winning values for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT1 state is about 1 / 109.2, respectively. In the RT1 lottery table 57, 34357 random numbers are assigned to the outliers, and the unfair selection probability (probability of outliers) in the role lottery in the RT1 state is about 1 / 1.9.

  In the RT1 lottery table 57, the winning value for the big bonus combination is not set. Therefore, the big bonus combination is not won again in the combination lottery in the RT1 state (the state between winning the big bonus combination in the combination lottery and winning the big bonus combination).

  After that, the combination of the symbols “Red 7”-“Red 7”-“Red 7” are arranged on the winning line (stopped display), and the big bonus role (RBB game) is started. Then, as shown in FIG. 4, the game state shifts from the RT1 state to the RT2 state.

  In the role lottery in the RT2 state during the big bonus game, the lottery table 57 for RT2 (in RBB) is used. In the lottery table 57 for RT2 (in RBB), as shown in FIG. 7, 8980 random values out of 65536 random numbers generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay combination in the combination lottery in the RT2 state during the big bonus game is about 1 / 7.3. In addition, 7001 random values are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. . Accordingly, the winning probabilities of the first to third bell roles in the RT2 state lottery during the big bonus game are about 1 / 9.361 (≈9.4), respectively, and the role lottery in the RT1 state Is slightly higher than the winning probability of the first to third bell roles. As the winning values for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT2 state during the big bonus game is about 1 / 109.2, respectively. It is. In the lottery table 57 for RT2 (in the RBB), 34353 random numbers are assigned to be out of place, and the unfavorable probability (probability of out of play) in the role lottery in the RT2 state during the big bonus game is About 1 / 1.9.

  In the lottery table 57 for RT2 (in RBB), the winning value for the big bonus combination is not set. Therefore, the big bonus combination is not won again in the combination lottery in the RT2 state during the big bonus game.

  The big bonus game ends when the total payout number of medals exceeds 50. On the other hand, in the regular bonus game, at least one of winning eight small roles or digesting eight games is an end condition. In the big bonus game, the regular bonus game is repeatedly executed until the total payout number of medals exceeds 50. If the total payout number of medals in the big bonus game exceeds 50, the big bonus game ends even before the regular bonus game end condition is satisfied.

  Accordingly, the progress of the big bonus game is roughly divided into three patterns according to the context of the end of the big bonus game and the achievement (establishment) of the end condition of the regular bonus game. That is, the pattern in which the big bonus game ends before the end condition of the regular bonus game is achieved, the pattern in which the big bonus game ends after the end condition of the regular bonus game is achieved, and the end of the regular bonus game There is a pattern in which the big bonus game ends as the conditions are achieved.

  FIG. 11 is a diagram illustrating an example of a pattern in which the big bonus game ends before the end condition of the regular bonus game is achieved.

  For example, as shown in FIG. 11, when 7 games have been consecutively won from the start of the big bonus game (regular bonus game), the first, second or third bell role is won in the correct push order (for the bell role). When winning), when the seventh game is over, the total number of medals paid up to that time is 56, and the big bonus game is over. At this time, the termination condition of the regular bonus game has never been satisfied. Therefore, in the pattern shown in FIG. 11 (the progress content of the big bonus game), the big bonus game ends before the end condition of the regular bonus game is achieved.

  FIG. 12 is a diagram illustrating an example of a pattern in which the big bonus game ends after the end condition of the regular bonus game is achieved.

  For example, as shown in FIG. 12, in the second game and the fourth game after the start of the big bonus game (regular bonus game), the replay role is lost in the winning or role lottery, and the first to the 5th game I won one of the 3rd Bells, but I won a small role consisting of a combination of predetermined symbols different from the Bells in the incorrect order of pushing, and in the 1st, 3rd and 6th-8th games If you win the first, second or third bell role in the correct push order (when you win the bell role), when the 8th game is over, the total number of medals so far will be 41 . Since the total payout number of medals does not exceed 50, the second regular bonus game is started thereafter. Then, in the first and second games of the second regular bonus game, when the first, second or third bell role is won in the correct push order (when the bell role is won), the second game is finished. At that time, the total payout number of medals so far is 57, and the big bonus game is ended. At this time, the termination condition of the regular bonus game is established once. Therefore, in the pattern shown in FIG. 12 (the progress content of the big bonus game), the big bonus game ends after the end condition of the regular bonus game is achieved.

  Note that the pattern shown in FIG. 12 is merely an example, and various patterns other than the pattern shown in FIG. 12 are conceivable in which the big bonus game ends after the regular bonus game end conditions are achieved.

  For example, in all the first to eighth games of the first regular bonus game, the replay role is lost in the winning or lottery, and the first, second, or second game is played in the first to seventh games of the second regular bonus game. There may be a pattern in which the big bonus game is ended by winning the third bell role in the correct pressing order.

  Also, in the 1st to 6th games of the first regular bonus game, the replay role is lost or the role lottery is lost, and in the 7th game, the 1st, 2nd or 3rd bell role is won in the correct push order. (Winning the Bell role), winning one of the 1st to 3rd Bell roles in the 8th game, but winning a small role consisting of a combination of predetermined symbols different from the Bell role in the incorrect answer order In the first to third games of the second regular bonus game, the first, second or third bell role is won in the correct push order (the bell role is won), and the first to third games are won in the fourth game. I won one of the bell roles, but I won a small role that consists of a combination of predetermined symbols different from the bell role in the incorrect order of pushing, and the replay role was dismissed in the 5th or 8th game in the winning or lottery drawing. First and second in the first and second games of the third regular bonus game The other is (a prize to the bell auditors) the third and winning in the correct push order to bell the role, pattern is also conceivable that big bonus game is finished.

  FIG. 13 is a diagram illustrating an example of a pattern in which the big bonus game is completed while the regular bonus game completion condition is achieved.

  For example, as shown in FIG. 13, six consecutive games from the start of the big bonus game (regular bonus game) are won in the first, second or third bell role in the correct push order (winning the bell role). In the seventh game, if one of the first to third bell roles is won, but if a small role consisting of a combination of predetermined symbols different from the bell role is selected in the order of incorrect answer, At the point of time, the total number of medals paid out so far is 49. Since the total number of medals paid out does not exceed 50, the 8th game is executed, and if the 1st, 2nd or 3rd bell role is won in the 8th game in the correct answer pressing order (winning the Bell role) When the eighth game ends, the total number of medals paid out so far reaches 57, and the big bonus game ends. Therefore, in the pattern shown in FIG. 13 (the progress content of the big bonus game), the end condition of the regular bonus game is achieved and the big bonus game is ended.

  The pattern shown in FIG. 13 is merely an example, and various conditions other than the pattern shown in FIG. 13 are conceivable as the regular bonus game end condition is achieved and the big bonus game ends.

  For example, in the first game after the start of the big bonus game (regular bonus game), the first to third bell roles are won, but the small role is composed of a combination of predetermined symbols different from the bell role in the incorrect order of pressing. In the case of winning, the first, second or third bell role is won in the 2nd to 6th games in the correct pressing order (winning the bell role), and the 1st to 3rd bell roles are won in the 7th game. If you win one of the prizes, you will win a small role consisting of a combination of predetermined symbols that is different from the bell role in the wrong answer pressing order, and the correct answer pressing order for the first, second, or third bell role in the 8th game In this case, a regular bonus ending condition is achieved and a big bonus game is ended.

  If the big bonus game progresses in a pattern in which the big bonus game ends before the regular bonus game end condition is achieved, as shown in FIG. 4, the game state still remains after the big bonus game ends. Is maintained in the RT2 state.

  In the role lottery in the RT2 state after the end of the big bonus game, the RT2 lottery table 57 is used. In the RT2 lottery table 57, as shown in FIG. 8, 8980 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay combination in the combination lottery in the RT2 state after the end of the big bonus game is about 1 / 7.3. Also, 7000 random numbers are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. . As a result, the winning probabilities of the first to third bell roles in the role lottery in the RT2 state after the end of the big bonus game are about 1 / 9.362 (≈9.4), respectively, the RT0 state and the RT1 state It is the same as the winning probability of the first to third bell roles in the role lottery. As the winning value for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT2 state after the end of the big bonus game is about 1/109. 2. As the winning value of the big bonus combination, 200 random numbers are set, and the winning probability of the big bonus combination in the combination lottery in the RT2 state after the end of the big bonus game is about 1 / 327.7. In the RT2 lottery table 57, 34156 random numbers are assigned as outliers, and the unfair chance probability (probability of outliers) in the role lottery in the RT2 state after the end of the big bonus game is about 1 / 1.9.

  When the big bonus game progresses in a pattern where the big bonus game ends after the regular bonus game end condition is achieved, or when the regular bonus game end condition is achieved and the big bonus game ends As shown in FIG. 4, the game state shifts from the RT2 state to the RT3 state in response to the establishment of the regular bonus game end condition.

  In the role lottery in the RT3 state during the big bonus game, the lottery table 57 for RT3 (in RBB) is used. In the lottery table 57 for RT3 (in RBB), as shown in FIG. 9, 43133 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay role in the role lottery in the RT3 state during the big bonus game is about 1 / 1.5, which is based on the winning probability of the replay role in the role lottery in the RT0 state, the RT1 state and the RT2 state. Is much higher. In addition, 7001 random values are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. . Thus, the winning probabilities of the first to third bell roles in the RT3 state lottery during the big bonus game are about 1 / 9.361 (≈9.4), respectively, in the RT0 state and the RT1 state. It is slightly higher than the winning probability of the first to third bell roles in the role lottery. As the winning value of the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT3 state during the big bonus game is about 1 / 109.2, respectively. It is. And in the lottery table 57 for RT3 (in RBB), 200 random values are assigned to the outliers, and the unlucky probability (probability of coming out) in the role lottery in the RT3 state during the big bonus game is It is about 1 / 327.7.

  In the lottery table 57 for RT3 (in RBB), the winning value for the big bonus combination is not set. Therefore, the big bonus combination is not won again in the combination lottery in the RT3 state during the big bonus game.

  When the game state transitions from the RT2 state to the RT3 state, the game state is maintained in the RT3 state even after the big bonus game ends.

  In the role lottery in the RT3 state after the end of the big bonus game, the RT3 lottery table 57 is used. In the RT3 lottery table 57, as shown in FIG. 10, 43133 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay role in the role lottery in the RT3 state after the end of the big bonus game is about 1 / 1.5, and the winning probability of the replay role in the role lottery in the RT0 state, the RT1 state and the RT2 state Much higher than. Also, 7000 random numbers are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. . As a result, the winning probabilities of the first to third bell roles in the role lottery in the RT3 state after the end of the big bonus game are about 1 / 9.362 (≈9.4), respectively, the RT0 state and the RT1 state It is the same as the winning probability of the first to third bell roles in the role lottery. As the winning value for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT3 state after the end of the big bonus game is about 1/109. 2. As the winning value of the big bonus combination, 200 random numbers are set, and the winning probability of the big bonus combination in the combination lottery in the RT3 state after the end of the big bonus game is about 1 / 327.7. In the lottery table 57 for RT3, three random numbers are assigned to the outliers, and the unlucky probability (probability of outliers) in the role lottery in the RT3 state after the end of the big bonus game is about 1 /. 21845.3.

  Thereafter, when the big bonus combination is won in the combination lottery in the RT2 state or the RT3 state, as shown in FIG. 4, the game state shifts from the RT2 state or the RT3 state to the RT1 state.

  As described above, in the big bonus game, until the total number of medals to be paid out exceeds 50, a bonus game with at least one of winning of a small role or completion of 8 games as an end condition is continuously performed. Can be executed.

  In the slot machine 1, the game state after the big bonus game is ended differs depending on the progress of the big bonus game. That is, if the regular bonus game end condition is achieved before the end of the big bonus game, and the previous game state is the RT2 state, the game state is set to the RT2 state in response to the completion of the end condition. Therefore, the player is more likely to win a replay role in the role lottery than in the RT2 state, and shifts to the RT3 state that is advantageous to the player. In the RT3 state, since the replay combination is won with high probability, the player can obtain medals by winning the small combination without reducing the number of medals owned (the number of possessions). When the game state transitions from the RT2 state to the RT3 state, the RT3 state continues even after the big bonus game ends. On the other hand, if the big bonus game ends without achieving the regular bonus game end condition, the game state does not change, and the RT2 state, which is the previous game state, continues even after the big bonus game ends. To do.

For this reason, during the big bonus game, the bonus game while giving the player a sense of expectation that the game state after the end of the big bonus game will be in the RT3 state, that is, a sense of achievement of the regular bonus game end condition. Can be entertained. As a result, a new interest by changing the game state after the end of the big bonus game according to the progress of the big bonus game without losing the original fun of the big bonus game that can be executed repeatedly. Can be added.
Second Embodiment

  FIG. 14 is a view showing game state transitions in the slot machine according to the second embodiment. 15, 16, 17, 18, 19, 20, and 21 are examples of lottery tables.

  In the slot machine 1, there are an RT0 state, an RT1 state, an RT2 state, an RT3 state, and an RT4 state as game states.

  Immediately after the slot machine 1 is powered on, the game state is the RT0 state (initial state).

  In the role lottery in the RT0 state, the lottery table 57 for RT0 is used. In the lottery table 57 for RT0, as shown in FIG. 15, 8978 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay combination in the combination lottery in the RT0 state is about 1 / 7.3. In addition, 7000 random numbers are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. The winning probabilities of the first to third bell roles in the role lottery in the RT0 state are about 1 / 9.362 (≈9.4), respectively. As the winning values for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probabilities for the watermelon role and the cherry role in the role lottery in the RT0 state are about 1 / 109.2, respectively. As the winning value of the big bonus combination, 200 random numbers are set, and the winning probability of the big bonus combination in the combination lottery in the RT0 state is about 1 / 327.7. In the lottery table 57 for RT0, 34158 random number values are assigned as outliers, and the unfair chance probability (probability of outliers) in the role lottery in the RT0 state is about 1 / 1.9.

  FIG. 14 shows that when a big bonus combination is won in the combination lottery in the RT0 state, that is, when the random value acquired from the random number counter matches one of the big bonus combination winning values set in the lottery table 57 for RT0. As shown, the game state shifts from the RT0 state to the RT1 state.

  In the role lottery in the RT1 state, the lottery table 57 for RT1 is used. In the lottery table 57 for RT1, as shown in FIG. 16, 8979 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay combination in the combination lottery in the RT1 state is about 1 / 7.3. In addition, 7000 random numbers are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. The winning probabilities of the first to third bell roles in the role lottery in the RT1 state are about 1 / 9.362 (≈9.4), respectively. As the winning values for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT1 state is about 1 / 109.2, respectively. In the RT1 lottery table 57, 34357 random numbers are assigned to the outliers, and the unfair selection probability (probability of outliers) in the role lottery in the RT1 state is about 1 / 1.9.

  In the RT1 lottery table 57, the winning value for the big bonus combination is not set. Therefore, the big bonus combination is not won again in the combination lottery in the RT1 state (the state between winning the big bonus combination in the combination lottery and winning the big bonus combination).

  After that, the combination of the symbols “Red 7”-“Red 7”-“Red 7” are arranged on the winning line (stopped display), and the big bonus role (RBB game) is started. Then, as shown in FIG. 14, the game state shifts from the RT1 state to the RT2 state.

  In the role lottery in the RT2 state during the big bonus game, the lottery table 57 for RT2 (in RBB) is used. In the lottery table 57 for RT2 (in RBB), as shown in FIG. 17, 8980 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay combination in the combination lottery in the RT2 state during the big bonus game is about 1 / 7.3. In addition, 7001 random values are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. . Accordingly, the winning probabilities of the first to third bell roles in the RT2 state lottery during the big bonus game are about 1 / 9.361 (≈9.4), respectively, and the role lottery in the RT1 state Is slightly higher than the winning probability of the first to third bell roles. As the winning values for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT2 state during the big bonus game is about 1 / 109.2, respectively. It is. In the lottery table 57 for RT2 (in the RBB), 34353 random numbers are assigned to be out of place, and the unfavorable probability (probability of out of play) in the role lottery in the RT2 state during the big bonus game is About 1 / 1.9.

  In the lottery table 57 for RT2 (in RBB), the winning value for the big bonus combination is not set. Therefore, the big bonus combination is not won again in the combination lottery in the RT2 state during the big bonus game.

  If the big bonus game progresses in a pattern in which the big bonus game ends before the regular bonus game end condition is achieved, as shown in FIG. 14, the game state still remains after the big bonus game ends. Is maintained in the RT2 state.

  In the role lottery in the RT2 state after the end of the big bonus game, the RT2 lottery table 57 is used. In the lottery table 57 for RT2, as shown in FIG. 18, 8980 random values out of 65536 random numbers generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay combination in the combination lottery in the RT2 state after the end of the big bonus game is about 1 / 7.3. Also, 7000 random numbers are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. . As a result, the winning probabilities of the first to third bell roles in the role lottery in the RT2 state after the end of the big bonus game are about 1 / 9.362 (≈9.4), respectively, the RT0 state and the RT1 state It is the same as the winning probability of the first to third bell roles in the role lottery. As the winning value for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT2 state after the end of the big bonus game is about 1/109. 2. As the winning value of the big bonus combination, 200 random numbers are set, and the winning probability of the big bonus combination in the combination lottery in the RT2 state after the end of the big bonus game is about 1 / 327.7. In the RT2 lottery table 57, 34156 random numbers are assigned as outliers, and the unfair chance probability (probability of outliers) in the role lottery in the RT2 state after the end of the big bonus game is about 1 / 1.9.

  When the big bonus game progresses in a pattern where the big bonus game ends after the regular bonus game end condition is achieved, or when the regular bonus game end condition is achieved and the big bonus game ends As shown in FIG. 14, the game state shifts from the RT2 state to the RT3 state in response to the satisfaction of the end condition of the regular bonus game.

  In the role lottery in the RT3 state during the big bonus game, the CZ replay role (chance replay role) is included in the lottery target role. In the slot machine 1 according to the second embodiment, the symbols arranged on the reel bands of the reels 4L, 4C, 4R (see FIG. 1) include the “CZ replay” symbol (chance replay symbol). When the CZ replay combination is won, it is allowed that the symbol combinations “CZ replay” − “CZ replay” − “CZ replay” are arranged on the winning line. When a combination of symbols “CZ replay”-“CZ replay”-“CZ replay” is arranged on the winning line, the player wins the CZ replay role, and one game can be executed without medal betting for the winning. Is done.

  In the lottery drawing in the RT3 state during the big bonus game, the lottery table 57 for RT3 (in RBB) is used. In the lottery table 57 for RT3 (in RBB), as shown in FIG. 19, instead of the replay combination, 8978 random values out of 65536 random numbers generated by the random number counter are selected for the CZ replay combination. It is set as a value. Thereby, the winning probability of the CZ replay combination in the combination lottery in the RT3 state during the big bonus game is about 1 / 7.3. In addition, 7001 random values are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. . Thus, the winning probabilities of the first to third bell roles in the RT3 state lottery during the big bonus game are about 1 / 9.361 (≈9.4), respectively, in the RT0 state and the RT1 state. It is slightly higher than the winning probability of the first to third bell roles in the role lottery. As the winning value of the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT3 state during the big bonus game is about 1 / 109.2, respectively. It is. In the lottery table 57 for RT3 (in RBB), 34355 random numbers are assigned to be out of place, and the unfair selection probability (probability of out of play) in the role lottery in the RT3 state during the big bonus game is About 1 / 1.9.

  In the lottery table 57 for RT3 (in RBB), the winning value for the big bonus combination is not set. Therefore, the big bonus combination is not won again in the combination lottery in the RT3 state during the big bonus game.

  When the game state transitions from the RT2 state to the RT3 state, as shown in FIG. 14, the game state is maintained in the RT3 state even after the big bonus game is over.

  In the role lottery in the RT3 state after the end of the big bonus game, the CZ replay role is included in the lottery target. In the role lottery in the RT3 state after the end of the big bonus game, the RT3 lottery table 57 is used. In the RT3 lottery table 57, as shown in FIG. 20, 8978 random values out of 65536 random values generated by the random number counter are set as winning values for the CZ replay combination. Thereby, the winning probability of the CZ replay combination in the combination lottery in the RT3 state after the end of the big bonus game is about 1 / 7.3. Also, 7000 random numbers are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. . As a result, the winning probabilities of the first to third bell roles in the role lottery in the RT3 state after the end of the big bonus game are about 1 / 9.362 (≈9.4), respectively, the RT0 state and the RT1 state It is the same as the winning probability of the first to third bell roles in the role lottery. As the winning value for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT3 state after the end of the big bonus game is about 1/109. 2. As the winning value of the big bonus combination, 200 random numbers are set, and the winning probability of the big bonus combination in the combination lottery in the RT3 state after the end of the big bonus game is about 1 / 327.7. In the RT3 lottery table 57, 34158 random numbers are assigned to be out of place, and the unlucky probability (probability of out of play) in the role lottery in the RT3 state after the end of the big bonus game is about 1 / 1.9.

  When the CZ replay winning combination is won in the winning lottery in the RT3 state after the end of the big bonus game, the game state shifts from the RT3 state to the RT4 state as shown in FIG.

  In the role lottery in the RT4 state, the lottery table 57 for RT4 is used. In the RT4 lottery table 57, as shown in FIG. 21, 43136 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay role in the role lottery in the RT4 state is about 1 / 1.5, which is much higher than the winning probability of the replay role in the role lottery in the RT0 state, the RT1 state, and the RT2 state. In addition, 7000 random numbers are set as winning values for the first to third bell combinations. Accordingly, the winning probabilities of the first to third bell roles in the role lottery in the RT4 state are about 1 / 9.362 (≈9.4), respectively, and the roles in the RT0 state, the RT1 state, and the RT2 state are each This is the same as the winning probability of the first to third bell roles in the lottery. As the winning values of the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT4 state is about 1 / 109.2, respectively. As the winning value of the big bonus combination, 200 random numbers are set, and the winning probability of the big bonus combination in the combination lottery in the RT4 state is about 1 / 327.7. In the lottery table 57 for RT4, there is no random number assigned to the outage, and no outage occurs in the role lottery in the RT4 state.

  When the big bonus combination is won in the combination lottery in the RT2, RT3 or RT4 state, the game state shifts from the RT2, RT3 or RT4 state to the RT1 state as shown in FIG.

  As described above, also in the slot machine 1 according to the second embodiment, the game state after the end of the big bonus game differs depending on the progress of the big bonus game. That is, if the regular bonus game end condition is achieved before the end of the big bonus game, and the previous game state is the RT2 state, the game state is set to the RT2 state in response to the completion of the end condition. To the RT3 state in which the CZ replay combination is included in the lottery target combination. When the game state transitions from the RT2 state to the RT3 state, the RT3 state continues even after the end of the big bonus game. When the CZ replay winning combination is won in the winning lottery in the RT3 state after the end of the big bonus game, the game state shifts from the RT3 state to the RT4 state. In the RT4 state, since the replay winning combination is won with high probability, the player can acquire medals by winning the small role without reducing the number of medals owned (the number of possessions). On the other hand, if the big bonus game ends without achieving the regular bonus game end condition, the game state does not change, and the RT2 state, which is the previous game state, continues even after the big bonus game ends. To do.

Therefore, as in the case of the first embodiment, the game state after the end of the big bonus game according to the progress of the big bonus game without losing the original fun of the big bonus game that can be executed by repeating the bonus game. New interests can be added by changing

<Third Embodiment>

  FIG. 24 is a view showing game state transitions in the slot machine according to the third embodiment. 25, 26, 27, and 28 are examples of lottery tables.

  In the slot machine 1, there are an RT0 state and an RT1 state as game states.

  Immediately after the slot machine 1 is powered on, the game state is the RT0 state (initial state).

  In the role lottery in the RT0 state, the lottery table 57 for RT0 is used. In the lottery table 57 for RT0, as shown in FIG. 25, 8978 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay combination in the combination lottery in the RT0 state is about 1 / 7.3. In addition, 7000 random numbers are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. The winning probabilities of the first to third bell roles in the role lottery in the RT0 state are about 1 / 9.362 (≈9.4), respectively. As the winning values for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probabilities for the watermelon role and the cherry role in the role lottery in the RT0 state are about 1 / 109.2, respectively. As the winning value of the big bonus combination, 200 random numbers are set, and the winning probability of the big bonus combination in the combination lottery in the RT0 state is about 1 / 327.7. In the lottery table 57 for RT0, 34158 random number values are assigned as outliers, and the unfair chance probability (probability of outliers) in the role lottery in the RT0 state is about 1 / 1.9.

  In the slot machine 1 according to the third embodiment, even if the big bonus combination is won in the combination lottery in the RT0 state and the big bonus combination is won, the game state is maintained in the RT0 state as shown in FIG. The

  In the lottery drawing in the RT0 state during the big bonus game, the lottery table 57 for RT0 (in RBB) is used. In the lottery table 57 for RT0 (in RBB), as shown in FIG. 26, 8978 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay combination in the combination lottery in the RT0 state during the big bonus game is about 1 / 7.3. In addition, 7001 random values are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. . As a result, the winning probabilities of the first to third bell roles in the role lottery in the RT0 state during the big bonus game are about 1 / 9.361 (≈9.4), respectively. It is slightly higher than the winning probability of the first to third bell roles in the role lottery in the RT0 state. As the winning values for the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT0 state during the big bonus game is about 1 / 109.2, respectively. It is. In the lottery table 57 for RT0 (in RBB), 34355 random numbers are assigned to be out of place, and the unlucky probability (probability of out of play) in the role lottery in the RT0 state during the big bonus game is About 1 / 1.9.

  In the lottery table 57 for RT0 (in RBB), the winning value for the big bonus combination is not set. Therefore, the big bonus combination is not won again in the combination lottery in the RT0 state during the big bonus game.

  If the big bonus game progresses in a pattern in which the big bonus game ends before the regular bonus game end condition is achieved, as shown in FIG. 24, the game state still remains after the end of the big bonus game. Is maintained in the RT0 state.

  In the role lottery in the RT0 state after the end of the big bonus game, the lottery table 57 for RT0 shown in FIG. 25 is used.

  When the big bonus game progresses in a pattern where the big bonus game ends after the regular bonus game end condition is achieved, or when the regular bonus game end condition is achieved and the big bonus game ends As shown in FIG. 24, the game state shifts from the RT0 state to the RT1 state in response to the establishment of the regular bonus game end condition.

  In the role lottery in the RT1 state during the big bonus game, the lottery table 57 for RT1 (in RBB) is used. In the lottery table 57 for RT1 (in RBB), as shown in FIG. 27, 43133 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay role in the role lottery in the RT1 state during the big bonus game is about 1 / 1.5, which is much higher than the winning probability of the replay role in the role lottery in the RT0 state. In addition, 7001 random values are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. . Accordingly, the winning probabilities of the first to third bell roles in the RT1 state lottery during the big bonus game are about 1 / 9.361 (≈9.4), respectively, and the role lottery in the RT0 state Is slightly higher than the winning probability of the first to third bell roles. As the winning value of the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT3 state during the big bonus game is about 1 / 109.2, respectively. It is. And, in the lottery table 57 for RT1 (in RBB), 200 random numbers are assigned to the outliers, and the unlucky probability (probability of coming out) in the role lottery in the RT1 state during the big bonus game is It is about 1 / 327.7.

  In the lottery table 57 for RT1 (in RBB), the winning value for the big bonus combination is not set. Therefore, the big bonus combination is not won again in the combination lottery in the RT1 state during the big bonus game.

  When the game state transitions from the RT0 state to the RT1 state, as shown in FIG. 24, the game state is maintained in the RT1 state even after the big bonus game ends.

  In the role lottery in the RT1 state after the end of the big bonus game, the RT1 lottery table 57 is used. In the RT1 lottery table 57, as shown in FIG. 28, 43133 random values out of 65536 random values generated by the random number counter are set as winning values for the replay combination. Thereby, the winning probability of the replay role in the role lottery in the RT1 state during the non-big bonus game is about 1 / 1.5, which is much higher than the winning probability of the replay role in the role lottery in the RT0 state. In addition, 7000 random numbers are set as winning values for the first bell role (bell role 1), the second bell role (bell role 2), and the third bell role (bell role 3), respectively. The winning probabilities of the first to third bell roles in the role lottery in the RT1 state during the non-big bonus game are about 1 / 9.362 (≈9.4), respectively. As the winning value of the watermelon role and the cherry role, 600 random numbers are set, respectively, and the winning probability of the watermelon role and the cherry role in the role lottery in the RT1 state during the non-big bonus game is about 1/109. 2. As the winning value of the big bonus combination, 200 random numbers are set, and the winning probability of the big bonus combination in the combination lottery in the RT1 state during the non-big bonus game is about 1 / 327.7. In the lottery table 57 for RT1, three random numbers are assigned to the outliers, and the unfair chance probability (probability of coming out) in the role lottery in the RT1 state during the non-big bonus game is about 1 / 21845.3.

  In the RT1 state, for example, if one of the first to third bell roles is won, but a small role consisting of a combination of predetermined symbols different from the bell role in the wrong answer pressing order is won, As shown in FIG. 24, the game state shifts from the RT1 state to the RT0 state.

  As described above, also in the slot machine 1 according to the third embodiment, the game state after the end of the big bonus game differs depending on the progress of the big bonus game. That is, if the regular bonus game end condition is achieved before the end of the big bonus game, if the previous game state is the RT0 state, the game state is set to the RT0 state in response to the completion of the end condition. To RT1 state. In the RT1 state, since the replay winning combination is won with high probability, the player can obtain a medal by winning the small role without reducing the number of medals owned (the number of possessions). On the other hand, when the big bonus game ends without achieving the regular bonus game end condition, the game state does not change, and the game state up to that point continues even after the big bonus game ends.

  Therefore, as in the case of the first and second embodiments, after the end of the big bonus game according to the progress of the big bonus game without impairing the original fun of the big bonus game that can be executed by repeating the bonus game. New interests can be added by changing the game state.

  As mentioned above, although several embodiment of this invention was described, this invention can also be implemented with another form.

  For example, the slot machine 1 may have an AT (assist time) function. When the AT function is activated, if the first, second or third bell combination is won in the lottery, the correct pressing order of the left stop button 19L, the middle stop button 19C and the right stop button 19R is notified. The

  Therefore, when the AT function is activated during the big bonus game, the player is pressing the left stop button 19L, the middle stop button 19C, and the right stop button 19R based on the notification of the correct pressing order. By deliberately pushing in a different pushing order and winning one of the first to third bell roles, by winning a small role consisting of a combination of predetermined symbols different from the bell role in the wrong answer pushing order, The number of medals to be paid out can be reduced so that the regular bonus game end condition is achieved during the big bonus game. As a result, in order to obtain an advantageous game state after the end of the big bonus game, the player aims to win another small role in the incorrect order of pressing the first to third bells. Game characteristics can be added to the big bonus game.

  Also, in the slot machine 1 according to the third embodiment, the AT function operates in the RT1 state, so that the first to third bell roles are won and won in the correct pressing order (the bell role is awarded). Therefore, the game state can be prevented from shifting from the RT1 state to the RT0 state.

  Furthermore, in each of the above-described embodiments, the game state transitions when the end condition of the regular bonus game is achieved and the big bonus game progresses in a pattern in which the big bonus game ends. However, when the end condition of the regular bonus game is achieved and the big bonus game progresses in a pattern in which the big bonus game ends, a configuration in which the game state does not shift from the previous game state may be adopted. .

  In addition, the specific numerical values (number of random values, winning probability, etc.) given in the above-described embodiments are merely examples, and can be changed as appropriate.

  In addition, various design changes can be made within the scope of matters described in the claims.
