Further, in a game state of not carrying over the specific bonus winning combination and having a possibility to win the specific bonus winning combination, when it turns out the specific lottery result, the game machine controls the symbol stop display to preferentially win the small winning combination with less putout balls so as to control it to a game state with the ball putout rate of less than 100%.SELECTED DRAWING: Figure 11

Description

  In a gaming machine such as a slot machine, a game value is input, a symbol is variably displayed in response to an operation of a start switch, and then a game in which the symbol is stopped by an operation of a stop switch is repeatedly executed. Here, in such a gaming machine, a plurality of types of roles defined by the stop display mode of the symbol are provided, and when the symbol is displayed in the stop display mode related to the role, it becomes a winning of the role, Processing according to the combination is executed. For example, when winning a small combination, the number of game values corresponding to the winning small combination is paid out. Each winning combination cannot be won unless winning in the winning lottery executed when the start switch is operated. That is, for a combination that is not won in the combination lottery, the stop display mode of the symbol related to the combination is not displayed regardless of the operation procedure (operation timing or operation sequence) of the stop switch.

  Also, in many of these gaming machines, when a bonus combination is won by a combination lottery, and the bonus combination is won, a special gaming state is started in which the probability of winning a small combination in the combination lottery combination lottery is higher than usual. Generally, the winning status of a small role ends in the game regardless of whether the winning or not winning of the role is won, but the winning status of the bonus role is not changed after the next game without winning the bonus role in the game. Carried over.

  In the special game state, since the small role winning probability in the role lottery is higher than usual, generally the payout rate in the special game state is 100% or more. However, in recent years, a gaming machine in which a special gaming state with a payout rate of less than 100% is also proposed (for example, Patent Document 1).

JP 2006-1116010 A

  The gaming machine described in Patent Document 1 can realize an unexpected game by providing a special game state in which the payout rate is less than 100%. However, in such a gaming machine, when the player is elected as a bonus combination that triggers the special gaming state, the player is determined to shift to a gaming state with a payout rate of less than 100%, so the player is discouraged. , There was a risk of lowering interest.

  This invention is made | formed in view of the present condition which concerns, and it aims at provision of the game machine which mounts the special game state with a payout rate of less than 100%, and can improve interest.

  The present invention is provided with a symbol display capable of variably displaying a plurality of types of symbols, and after the symbols on the symbol display are variably displayed with the operation of the start switch, the symbols on the symbol display are triggered by the operation of the stop switch. In a gaming machine that executes a game in which a symbol is displayed in a stopped state and performs a process corresponding to the stop display mode of the symbol, the game state control means for controlling the gaming state and the symbol stop display mode of the symbol display A symbol lottery means for executing a symbol lottery for determining whether or not a plurality of types of symbols have been won, and a symbol control for controlling to stop and display symbols according to the symbol selected in the symbol lottery and the operation of the stop switch. And a winning determination means for determining that the winning combination has been won when the symbol display on the symbol display is displayed on the symbol display, the winning combination at the time of winning The gaming state control, including a small combination that pays out a technical value to the player, and a bonus combination that shifts to a special gaming state in which the winning probability of the small combination increases more than usual in the combination lottery at the time of winning a prize The means includes a specific bonus carry-over gaming state in which a game is performed in a state where the specific bonus combination is not won in the game won in the combination lottery and the winning state of the specific bonus combination is carried over, and the specific bonus combination It is possible to control the game state between a specific bonus non-carry-over gaming state that can be won for the specific bonus role in the role lottery and a specific bonus special game state that is shifted by winning the specific bonus role The special bonus special game state is a game state with a payout rate of less than 100%, and the combination lottery means includes the specific bonus non-carry-over game state and In the specific bonus carryover gaming state, the first lottery and the lottery that can be the result of the specific lottery in which the first small role and the second small role with higher gaming value paid out at the time of winning are selected simultaneously And the probability that the specific lottery result in the combination lottery is the same probability in the specific bonus non-carryover gaming state and the specific bonus carryover gaming state, and the symbol control means performs the specific lottery in the combination lottery When the lottery result is obtained, in the specific bonus non-carry-over gaming state, the symbol stop display is controlled so that the first small combination wins in preference to the second small combination, and the specific bonus carry-over is performed. In the gaming state, by controlling the symbol stop display so that the second small combination wins in preference to the first small combination, the payout rate in the specific bonus carryover gaming state is set to the specific bonus non-display state. Out of play carry game The specific bonus non-carry-over gaming state is a gaming state with a payout rate of less than 100%, and the specific bonus carryover gaming state is a gaming state with a payout rate of 100% or higher.

FIG. 5 shows the control contents of the CPU of the main control means 20 and the control contents of the main control process constituting the game contents. Details of steps S1 to S9 executed in the main control process are as follows.
S1: After the previous game is over or after the power is turned on, the state of the RAM and ROM is checked. If there is no abnormality, the medal insertion operation is validated. Then, it is detected whether or not the number of medals required for one game has been inserted or a bet operation from a credit has been performed, and the system waits until any one is operated. When it is detected that a predetermined number of medals have been inserted or a bet operation has been performed, the start switch 6 is activated. In the slot machine 1 of this embodiment, a game of three bets that normally requires the insertion of three medals per game is performed. In the challenge bonus game state described later, two medals per game are played. A two-wager game that requires insertion is performed.
S2: Wait until the start switch 6 is operated.
S3: When the start switch 6 is operated, rotation of each reel 9 is started. In addition, the lottery is executed in response to the operation of the start switch 6. In the combination lottery, a lottery value is extracted from the random number generator, and it is determined whether or not various types of combinations are won based on the extracted lottery value. Then, the result of the winning lottery is stored in the RAM, and a command for notifying the winning lottery result is transmitted to the sub-control means 21. That is, the role lottery means according to the present invention is mainly realized by the processing of step S3.
S4: Wait until the stop switch 7 is operated.
S5: When the stop switch 7 is operated, the rotation angle at which the corresponding reel 9 is stopped is determined, and the corresponding reel 9 is stopped at the rotation angle, so that the symbol of the reel 9 is stopped and displayed on the effective line. To do.
S6: Steps S4 and S5 are repeated until the rotation of all reels 9 is stopped. That is, the symbol control means according to the present invention is mainly realized by the processing of steps S4 to S6.
S7: It is determined whether or not the combination of symbols stopped and displayed on the active line matches the combination of symbols corresponding to the combination. If it matches the symbol combination related to any combination, it is determined that the combination is won. Then, a command for notifying the determination result is transmitted to the sub-control means 21. That is, the winning determination means according to the present invention is mainly realized by the process of step S7.
S8: Processing related to the payout of medals is performed according to the determination result of the winning determination processing. Specifically, when it is determined that a small combination described later has been won, the payout number corresponding to the winning small combination is added to the credit, and when the credit exceeds a predetermined number (50), Pay out the excess medals. Further, when it is determined that a re-game player to be described later has been won, the next game can be executed without inserting medals.
S9: The gaming state is shifted according to the result of the winning determination process or the like. For example, when a bonus combination is won, a bonus game state to be described later is entered. Further, when the bonus combination is won in the game won for the bonus combination, the game is shifted to the carryover gaming state described later. Further, if the bonus game state end condition is satisfied, the bonus game state is ended. That is, the gaming state control means according to the present invention is mainly realized by the processing of step S9.

  In the slot machine 1 of the present embodiment, a plurality of types of roles defined by combinations of symbols of the three reels 9 that stop on the effective line are set. In this embodiment, as shown in FIGS. 6 and 7, 74 types of combinations are set, and these are roughly divided into 45 types of general combinations and 29 types of bonus combinations. Further, the general combination is further classified into 44 types of small combinations and one type of replay combination. A small combination is a combination in which the number of medals of a payout assigned to each combination at the time of winning a prize is paid out to the player, and is classified into a 13-piece combination, a 3-piece combination, and a single-piece combination according to the number of payouts. In the two-sheet betting game described later, the payout number of all small roles is two. Further, the re-playing role is a role that enables the next game to be executed without inserting medals at the time of winning a prize. In addition, the portion described as “any” in the symbol combination indicates that any symbol is allowed.

  The bonus combination is a combination that shifts to a bonus gaming state in which a winning combination of a small combination is increased in a combination lottery when winning a prize. The bonus combination is classified into three types: a big bonus combination (hereinafter abbreviated as BB), a challenge bonus combination (hereinafter abbreviated as CB), and a regular bonus combination (hereinafter abbreviated as RB). Depending on the type of bonus combination to be won, it is configured to shift to a different bonus game state.

  As described above, in each game, a role lottery is executed in response to the operation of the start switch 6, and it is determined whether or not each winning combination has been won. Here, in the role lottery, the winning combination is not determined for each role, and as shown in FIGS. 8 and 9, a plurality of role groups in which one or more roles are grouped are set, and based on the extracted lottery values. The winning of any one role group or the defeat of all the role groups is determined. Here, when the winning combination group includes a plurality of combinations, all the combinations included in the combination group will be simultaneously selected. In addition, when all the winning groups are lost, all types of winning combinations are lost, that is, lost. For example, the role group “BE_01” in FIG. 8 includes 17 types of small roles of BEA1, ATA1 to ATA6, and ATB1 to 10. If the winning group “BE — 01” is won in the winning lottery, all 17 types of small roles included in the winning group are won. In the present embodiment, a combination group including both a general combination and a bonus combination and a combination group including both a replay combination and a small combination are not set. In addition, the three types of bonus combinations of the BB combination, the CB combination, and the RB combination are set not to win two or more types of bonus combinations at the same time, but to win alone. In this embodiment, the winning state of the general role disappears in the game regardless of whether or not the game is won, but as a general rule, the winning state of the bonus role is until the bonus role is won. Carried over after the next game.

  The role lottery will be described in detail. In the role lottery, lottery values in the range of 0 to 65535 are extracted regardless of the gaming state. The 65536 lottery values are assigned to any of the winning groups or loses, and the winning winning group or the lost is determined depending on which of the extracted lottery values is assigned. FIG. 10 is a chart showing the lottery probability of the role lottery at the valid setting value “1”. In addition, the numerical value which shows the lottery probability in FIG. 10 has shown the number which allocated 65536 lottery values with respect to each role group (or losing), and the value which divided the numerical value in FIG. This is the actual lottery probability. Note that the lottery probability of the combination lottery varies somewhat depending on the effective setting value, but is within a range that does not affect the operational effects of the present invention, so the lottery probability at other effective setting values is omitted.

  As shown in FIG. 10, the lottery probability of the combination lottery is defined for each gaming state and is different depending on the gaming state. Note that the normal gaming state (normal) in FIG. 10 is a gaming state at the time of factory shipment that is neither a bonus gaming state nor a carryover gaming state. The lottery probability will be described taking the role lottery in the normal game state as an example. As shown in FIG. 10, in the normal game state, a lottery value “9000” is assigned to the role group (RP_01) related to the re-game player. ing. For this reason, in the combination lottery in the normal gaming state, a re-game combination is won with a probability of about 14% (9000/65536). In the normal gaming state, lottery values are assigned to the role group (BB_01, 02) related to the BB role and the groove role (CB_01, 02) related to the CB role, but the role group (RB_01, 02) is not assigned a lottery value. For this reason, in the role lottery in the normal gaming state, the BB role and the CB role are won at the lottery probabilities assigned to each, but the RB role is not won.

  As described above, in each game, when the stop switch 7 is operated, a process of stopping the rotation of the reel 9 corresponding to the stop switch 7 and displaying the symbols on the active line is performed. In the reel 9 stop control, the reel 9 is stopped at a rotation angle corresponding to the winning combination in the winning lottery and the operation of the stop switch 7, thereby controlling the symbols to be stopped and displayed on the active line. In other words, the symbol stop display control according to the present invention is realized by the reel 9 stop control.

  Specifically, the slot machine 1 stops the reel 9 corresponding to the stop switch 7 within a stop delay period of 190 ms from the operation of the stop switch 7. Since the slot machine 1 can slide the symbol from 0 to 4 frames with respect to the effective line within the stop delay period, in the stop control of the reel 9, the symbol with respect to the effective line is started from the operation point of the stop switch 7. By determining how many frames to slide, the symbols that are stopped and displayed on the active line are controlled. That is, when the stop switch 7 is operated, when the stop switch 7 is operated, the symbols within the range of 0 to 4 frames are selectively stopped and displayed on the effective line. Symbols outside the 0-4 frame slip range cannot be stopped and displayed on the active line.

  The stop control of the reel 9 will be described in detail. First, the slot machine 1 controls the symbols to be stopped and displayed on the active line so as not to win a winning combination not won in the winning lottery. For this reason, the winning combination will never be awarded to the winning combination.

  Further, the slot machine 1 controls the symbols to be stopped and displayed on the active line so that the winning combination in the winning lottery is awarded as much as possible. Here, in the combination lottery, as described above, a plurality of combinations may be won simultaneously. Further, when the winning state of the bonus combination is carried over, the carried over bonus combination is in a state of being won at the same time as the general combination won in the combination lottery after the next game. As described above, when a plurality of winning combinations are simultaneously won, the slot machine 1 validates the symbol combination related to the winning winning combination with one or more winning winning combinations as winning winning combinations. Stop control of the reel 9 is performed so that stop display is given priority on the line.

  For example, in a state in which a bonus combination and a general combination are simultaneously won, the slot machine 1 controls the reel 9 to stop the general combination with priority over the bonus combination with the general combination as a winning combination. Further, in a state where a plurality of types of small combinations are simultaneously won, the slot machine 1 selects any one of the 13-piece combination, the 3-piece combination, and the single-piece combination according to the winning state of the combination. In addition, one single combination is classified into one single combination A to F, and when one single combination becomes a winning combination, one of these single combinations A to F is generally set as a winning combination.

The winning winning combination is roughly divided into a timing unquestioned combination and a timing combination.
Specifically, in FIGS. 8 and 9, a role marked with “*” is a timing unquestioned role, and the other is a timing role. The timing unquestionable role is composed of a combination of symbols that can stop and display the required symbols on the active line within the stop delay period at any timing. If the winning priority role is a timing unquestionable character, the stop switch 7 Regardless of the operation timing, you will always win the unquestioned timing. The timing combination is composed of a combination of symbols that can stop and display the required symbols on the active line within the stop delay period only within a certain range of timings. If the winning combination is the timing combination, the stop switch 7 Depending on the operation timing, the timing combination may not be won and may be missed. Note that if a winning combination can be won when the timing combination is missed, the other combination may be won by stop control of the reel 9. Also, if any winning combination cannot be won when the timing combination is missed, any combination of symbols on the active line is not stopped on the active line by the stop control of the reel 9 and is not won. .

FIG. 11 shows the priority order in the stop control of the reels 9 according to the gaming state and the result lottery result.
The normal gaming state will be described as an example. First, in the normal gaming state, if the winning lottery result is lost, all the winning combinations are not won. The reel 9 is stopped to prevent winning. On the other hand, when the winning combination group (RP_01) related to the replaying combination is won, the slot machine 1 performs the stop control of the reel 9 so as to stop the symbol combination related to the replaying combination (RPC1) on the effective line. I do. Since the re-gamer (RPC1) is a timing-unrelated role, when a re-game player is elected, the re-game player is always won.

  In addition, when winning the role group of BE_01 in the role lottery, 13 winning combinations (BEA1) and 1 winning combination (1 winning combination A, C) will be won simultaneously (see FIG. 8). In the state, the single winning combination A becomes the winning priority combination. The single combination A is a timing combination, and if the operation timing of the third stop switch 7 is inappropriate, the single combination A will be missed. In addition, as shown in FIG. 7, the symbols of the middle reel 9 and the right reel 9 constituting each symbol combination are different for the one-piece combination A, the one-piece combination C, and the thirteen-piece combination (for example, The symbol of the middle reel 9 is composed of T1 or T2 in the single-sheet combination A, but is composed of MD, R7, G7, BR, or C2 in the single-sheet combination C, and in the 13-sheet combination (BEA1). (It is composed of RP.) When two symbol combinations of one-piece combination A are stopped and displayed on the active line, the combination of symbols of one-piece combination C and thirteen-piece combination cannot be stopped and displayed. For this reason, when one winning combination A is missed by operating the third stop switch 7 at the time of winning the winning group of BE_01, the winning control is made by the reel 9 stop control.

  In addition, when winning the winning group BE_02 in the winning lottery, 13 winning combinations (BEA1) and 1 winning combination (1 winning combination A, C, D) will be won simultaneously (see FIG. 8). In the gaming state, the 13-piece combination (BEA1) is the winning combination. Since the 13-piece combination (BEA1) is an unquestioned timing combination, in this case, the 13-piece combination is always won regardless of the operation procedure of the stop switch 7.

  Similarly to BE_01 and 02, when a winning group of BE_03 to 13 is won, 13 winning combinations and 1 winning combination will be won simultaneously. In the normal gaming state, either a 13-piece winning combination or a single-winning winning combination becomes the winning priority combination depending on the winning combination group. Specifically, if BE_05 is won, the 13-piece combination will be the winning combination and the 13-piece combination will be won. On the other hand, when other winning groups (BE_03, 04, 06-13) are won, one winning combination becomes the winning priority combination. Here, at the time of winning the combination of BE_03, 04, 06-12, one of the single combination A and one single combination B is won, and the winning combination is the winning combination. Since both the one-piece combination A and the one-piece combination B are timing combinations, depending on the operation timing of the stop switch 7, one combination is missed and no winning is made. On the other hand, at the time of winning combination of BE_13, both the one-piece combination A and the one-piece combination B are won, and both of the one-piece combinations become the winning combination. In such a case, one winning combination is won regardless of the operation timing of the stop switch 7.

  In addition, when winning a combination of AT_01 to 04 in the combination lottery, a plurality of single combinations including a single combination D will be won (see FIG. 9). In the normal gaming state, in such a case, the one-piece combination D, which is an unrelated timing, becomes the winning combination, and the single-piece combination relating to the one-piece combination D is won regardless of the operation timing of the stop switch 7. In this embodiment, when winning AT_01-04, the single-player combination D is given a winning combination in the normal gaming state or the like. However, except for the BB carryover gaming state and the RB carryover gaming state described later, Instead of D, another winning combination (one winning combination A or one winning combination B) that is won simultaneously with the single winning combination D may be used as the winning priority winning combination.

  Further, when winning the SP_01 to 03 role group in the role lottery, two of the three one-piece roles included in the one-piece role E will be won simultaneously (see FIG. 9). The combination of the two one-sheet combinations is a timing combination, and the one-piece combination is missed at a rate of about 1/3 and is not won.

  If the winning group CH_01 is won, three winning combinations and one winning combination (one winning combination F) will be won simultaneously (see FIG. 9). In the normal game state, in such a case, the three-piece combination that is the timing combination is set as the winning priority combination. The three-piece combination is a combination of symbols in which a missing combination occurs at a ratio of 1/2. If the three-piece combination is missed, the single-piece combination (one-piece combination F) is always won by the stop control of the reel 9.

  In addition, in the case of lottery in the normal game state, when the winning group (BB_01, 02) related to the BB winning is won, the winning BB winning becomes the winning priority winning. However, since the BB combination won in the combination lottery is a timing combination, depending on the operation timing of the stop switch 7, the BB combination is missed and no winning is made. In addition, when winning the winning group (BB_01, 02) related to the BB role, the winning of the BB role is notified by the image display 10, the speaker 11, and the effect lamp 12 before the stop switch 7 is operated. . Therefore, in a game won for the BB combination, the player can win the BB combination by operating the stop switch 7 at an appropriate timing by a so-called pushing operation. As described above, even if the player misses the BB combination, the winning state of the BB combination does not disappear and is carried over after the next game.

  In addition, in the case of a combination lottery in the normal game state, when winning the role group (CB_01, 02) related to the CB role, if the winning of CB_01, CBB10 to 12 will be the winning winning role, and if the winning of CB_02, CBB16 ~ 18 becomes the winning priority role. The CBBs 10 to 12 and the CBBs 16 to 18 are timing combinations, and are configured so as to be non-winning when these winning priority combinations are missed. Here, when the winning group (CB_01, 02) related to the CB role is won, the winning of the CB role is notified by the image display 10, the speaker 11, and the effect lamp 12 before the stop switch 7 is operated. However, depending on the skill of the player, the winning priority role cannot be awarded. At the time of such notification, it is not notified which winning group has been won, and at the operation timing at which a winning winning combination related to one winning group can be won, the winning priority winning combination related to the other winning group is missed. This is because it is configured to win. For this reason, at the time of winning the role group related to the CB role, the CB role is won at a rate of approximately ½, and the winning state of the CB role is carried over at a rate of ½. In this embodiment, the player is notified of the winning of the CB role, but the player is not notified of the winning of the CB role and the player cannot recognize or win the CB role in the production. You may make it do.

The gaming state of the slot machine 1 will be described below.
As shown in FIG. 12, in addition to the above-described normal gaming state, the slot machine 1 according to the present embodiment wins the CB role in the normal gaming state and transitions by winning and in the normal gaming state. The BB gaming state which shifts by winning the BB combination and winning a prize is provided. In addition, the slot machine 1 has a CB carryover game state that shifts when the winning CB combination is missed in the normal gaming state, and a BB carryover gaming state that shifts when the winning BB role is missed in the normal gaming state. It has.

  As described above, the normal gaming state is not a bonus gaming state, and is a gaming state that does not correspond to a carryover gaming state in which a bonus combination win is carried over. As shown in FIG. 10, the two types of bonus combination, CB combination and BB combination, can be won only in the combination lottery in the normal gaming state. As shown in FIG. 11, in the lottery in the normal gaming state, even if the winning group of the one and 13 winning combinations is won at the same time, the single winning combination becomes a winning priority frequently, so the normal gaming state The payout rate is less than 100% (about 34%). In addition, the payout rate in each game state is the expected value of the number of medals to be paid when a player who is familiar with the game contents operates to maximize the number of payouts (payout number) in each game state. , The percentage divided by the number of medals inserted during the gaming state.

Specifically, the payout rate in each gaming state can be calculated based on the stop control mode of the reel 9 and the lottery probability of the winning lottery. Hereinafter, a method for calculating the payout rate in the normal gaming state will be described as an example.
First, in the normal game state, stop control of the reel 9 is performed in a manner corresponding to the winning group won in the winning lottery. For this reason, as shown in FIG. 13, when the player operates the stop switch 7 so as to maximize the payout number, the winning combination is won at a certain frequency according to the winning group, In this case, the winning winning combination will be missed, and the average number of payouts at the time of winning each winning group will be constant. For example, if the winning group of RP_01 is won, the winning priority combination (replaying combination) is 100% won by the stop control of the reel 9. Since the re-playing role is equivalent to paying out 3 medals necessary for starting the next game, the average payout number when winning the role group of RP_01 is 3. Further, when the winning group BE_01 is elected, the player wins the winning priority role (single winning role A) at a frequency of 50%, and loses the winning priority role at a frequency of 50% and becomes non-winning. For this reason, the average number of payouts when winning the winning group is 0.5 (the number of payouts when winning a single combination A × 0.5 + the number of payouts when not winning × 0.5). In this way, in the normal gaming state, the average payout number at the time of winning each role group can be calculated based on the stop control of the reels 9, and each role group is won with a certain lottery probability in each game. Since it is configured, as shown in FIG. 13, if the average number of payouts at the time of winning each winning group and the winning probability of the winning group are summed up for all the winning groups, in the normal gaming state The expected value of the number of payouts per game can be calculated. Then, if the expected value of the number of payouts is divided by the number of medals inserted per game in the normal game state (3), the payout rate in the normal game state (about 34%) can be calculated. Note that the game play rate in the normal game state is a value calculated from the lottery probability of the role lottery in the case of the effective setting value “1”. In this embodiment, the game play rate in each game state is set to the effective setting. The fluctuation range according to the value is small, and the payout rate in each gaming state does not vary between 100% or more and less than 100% depending on the effective setting value. For this reason, in this specification, with respect to the game play rate in each game state, the approximate play rate is expressed as “about xx%”, so that the change in the game play rate in each game state in accordance with the effective setting value. Ignore and explain. In addition, although the explanation of the calculation process is omitted, the game play rate in each gaming state described later is calculated in the same manner as the above calculation method for the game play rate in the normal game state.

  The CB gaming state is a bonus gaming state that is shifted by winning a CB role. When the CB role is won in the normal gaming state and the game is won, or in the CB carryover gaming state, the CB role that has been carried over is won. It starts when you do. In gaming states other than the CB gaming state, a game in which three medals are inserted per game (three bets) is performed, whereas in the CB gaming state, an exception is a game in which two medals are inserted per game ( 2 bets). As shown in FIG. 7, in the game with two bets, the payout of all small roles is two. In the CB gaming state, all types of small roles are simultaneously won with a probability of 100% in the role lottery. For this reason, in the CB gaming state, regardless of the operation procedure of the stop switch 7, a small role is always won in each game and two medals are paid out. In the CB gaming state, exceptionally, the stop control of the middle reel 9 is not controlled. That is, when the corresponding stop switch 7 is operated while the middle reel 9 is rotating, the slot machine 1 stops the middle reel 9 on the spot without sliding any symbols.

  The CB gaming state ends when the cumulative payout number of medals reaches 3 or more, and shifts to the normal gaming state. As described above, in the CB gaming state, since two medals are always paid out in each game, the CB gaming state always ends in two games. Therefore, the CB gaming state ends when a total of four medals are inserted in two games, and a total of four medals are paid out. That is, the payout rate in the CB gaming state is 100% regardless of the set value. As described above, since the CB gaming state according to the present embodiment is completed in two games, when winning the CB role in the normal gaming state and winning the CB role in the game and shifting to the CB gaming state, the two games Later, the normal game state is restored.

  The CB carryover gaming state is a gaming state in which the CB role is won in the normal game state lottery, but the CB role is not won in the game and the CB role winning state is carried over and the game is executed. In a game where the CB role is won in the normal gaming state, the CB role is won with a probability of approximately 1/2. On the other hand, when the CB carryover gaming state is entered, the winning of the CB role is carried over, but the CB role Probability of winning will be drastically reduced to less than 1% per game. This is due to the winning lottery probability and the reel 9 stop control in the CB carryover gaming state.

  Specifically, as shown in FIG. 10, in the CB carryover game state, the lottery values of the role lottery are not assigned to the loser and the bonus role, and the general lottery is always won in the role lottery. In other words, in the CB carryover game state, the game is always performed in a state where the general combination and the CB combination are won simultaneously. As described above, when a general combination and a bonus combination are simultaneously selected, the general combination is given a winning combination in the stop control of the reel 9, so that in the CB carryover gaming state, in most cases, it is related to the operation procedure of the stop switch 7. The symbol combination relating to the CB combination cannot be stopped and displayed on the active line.

  As shown in FIG. 11, in the CB carryover game state, the CB role is won only when the SP_01, SP_02, SP_03 role group is won and one of the role groups included in these role groups is missed. It is. Specifically, when the SP_01, SP_02, and SP_03 winning groups are won, one single combination (one single combination E) according to the operation timing of the stop switch 7 corresponding to the left reel 9 is selected. ) Is configured to miss. Then, when one winning combination is missed, stop control of the reel 9 is performed so that the winning combination CB (CBB 1 to 9 or CBB 13 to 15) wins, and the winning combination CB is won.

  As described above, in this embodiment, when the CB role is lost in the normal game state and the CB carryover game state is shifted to, it becomes difficult to win the CB role that has won the winning state, and the CB game state is passed through. Therefore, it takes a large number of games to return to the normal gaming state. As described above, the CB carryover gaming state according to the present embodiment is a gaming state in which it is difficult to shift to another gaming state, and most of the games of the slot machine 1 according to the present embodiment are performed in the CB carryover gaming state. It is configured. In this embodiment, the payout rate in the CB carryover gaming state is set to less than 100% (about 45%).

  The BB gaming state is a bonus gaming state that shifts by winning a BB role. When the BB role is won in the normal gaming state and the game is won, or in the BB carryover gaming state, the BB role is won. It starts when you do. In the BB gaming state, winning / winning of the RB role is possible. When winning the RB role, a bonus game (RB gaming state) corresponding to the RB role is started in the BB gaming state.

  As shown in FIG. 14, the BB gaming state includes an RB gaming state that shifts by winning the RB role, a BB general gaming state that does not carry over the winning state of the RB role and can win the RB role in the role lottery, It consists of three states of RB carryover gaming state that has carried the winning state of the combination. As will be described later, in the BB general gaming state and the RB gaming state, the payout rate is less than 100%, and in the RB carryover gaming state, the payout rate is 100% or more, but the payout rate in the RB carryover gaming state is a game. Therefore, the BB gaming state is a gaming state with a payout rate exceeding 100% (about 250%) as a whole.

  The BB general gaming state is an initial state of the BB gaming state, and is controlled to the BB general gaming state at the start of the BB gaming state. As shown in FIG. 10, in the role lottery in the BB general gaming state, the lottery value is assigned to the role group (RB — 01, 02) including the RB role, and the RB role can be won with a probability of about 1/3. Further, the lottery probability of the small role is the same as that in the normal game state, and the re-game player and the lost game are not assigned lottery values and cannot be won. Thereby, the payout rate in the BB general gaming state is suppressed to less than 100% (about 17%).

  As shown in FIG. 11, when the winning group (RB_01, 02) related to the RB winning combination is won in the BB general gaming state, the winning RB winning combination becomes the winning winning combination. Since the RB combination which becomes the winning priority combination is a timing combination, depending on the operation timing of the stop switch 7, the RB combination is missed and no winning is made. In addition, when the winning group related to the RB role is won, the winning of the RB role is notified by the image display 10, the speaker 11, and the effect lamp 12 before the stop switch 7 is operated. As described above, in the present embodiment, the RB carryover gaming state is more advantageous than the RB gaming state, so in the game won for the RB role, the player can stop by the so-called pushing operation. By selecting the operation timing of the switch 7, it is operated to avoid winning of the RB combination. As shown in FIG. 6, in the symbol combinations of all RB roles, the symbol of the left reel 9 is “T2 (tomato B)”, and as shown in FIG. ) "Has only one frame on the left reel 9, so the player operates the stop switch 7 corresponding to the left reel 9 at a timing at which" T2 (tomato B) "cannot be stopped and displayed on the active line. Then, even if the winning combination of the RB combination is made, symbol combinations other than the combination of the RB combination can be stopped and displayed on the active line to avoid winning the RB combination.

  The RB gaming state is a bonus gaming state that is shifted by winning the RB role. When the RB role is won in the BB general gaming state and the game is won, or the RB role is carried over in the RB carryover gaming state. Starts when winning. Here, as shown in FIG. 10, in the lottery drawing in the RB gaming state, lottery values are assigned to two role groups (AL_1, AL_2) and losers. AL_1 is a combination group including all 13-piece combinations and three-piece combinations, and the reel 9 is controlled to stop so that any 13-piece combination can be won without being missed. AL_2 is a combination group including all the single combinations, and the reel 9 is controlled to stop so that any one combination can be won without being missed. Note that AL_1 is not limited to a 13-piece combination and a 3-piece combination, and may be a combination group including all small combinations including one combination.

  In the RB gaming state, lottery values are assigned to the two role groups so that the winning probability of each small role is higher than that in the normal gaming state. The payout rate in the RB gaming state is higher than that in the normal gaming state, but is suppressed to less than 100% (about 50%). The RB gaming state ends when 12 games are consumed or when a general combination is won eight times, and the BB gaming state returns to the BB general gaming state.

  The RB carryover gaming state is a gaming state in which the RB role is won in the game lottery in the BB general gaming state, but the RB role is not won in the game, and the RB role winning state is carried over and executed. As shown in FIG. 10, in the RB carryover gaming state, the winning probability of the winning combination of the re-gamer is higher than that of the BB general gaming state, but the winning probability of the small role is the same as that of the BB general gaming state. . In the RB gaming state, the winning state of the RB role (whether or not the winning is carried over) is different from the BB general gaming state. The stop control mode of the reel 9 is changed so that the frequency of playing is higher than that in the BB general gaming state, thereby significantly improving the payout rate compared with the BB general gaming state, Realize a very advantageous rate.

  Specifically, as shown in FIG. 10, in the BB general game state and the RB carryover game state, when 13 types of role groups (BE_01 to 13) are won in the role lottery, the 13 role and the 1 role are obtained. Win simultaneously. The probability of winning the 13 types of role groups is the same in the BB general gaming state and the RB carryover gaming state. In this embodiment, as shown in FIG. 11, when 11 types of role groups (BE_01, 03, 04, 06 to 13) are selected, in the BB general gaming state, one (1) The winning combination is A or a single combination B). In this way, when one winning combination is a winning combination, depending on the operation timing of the stop switch 7, the winning combination is one or not, and the 13 winning combination is not won regardless of the operating timing of the stop switch 7. On the other hand, when the same 11 types of role groups (BE_01, 03, 04, 06 to 13) are won, in the RB carryover gaming state, 13 winning combinations are set as winning priority roles. As described above, when the 13-piece combination is set as the winning combination, the 13-piece combination is always won regardless of the operation timing of the stop switch 7, and the single-piece combination is not won. In the remaining two types of combination groups (BE_02, BE_05), the 13-piece combination is the winning combination in any game state.

  As described above, in this embodiment, the winning probability of the winning group that is simultaneously won for the 13 winning combination and the 1 winning combination is the same in the BB general gaming state and the RB carryover gaming state. When winning (BE_01, 03, 04, 06-13), the BB general gaming state has a single winning combination, whereas the RB carryover gaming state has a 13 winning combination, The frequency of winning 13 winning combinations in the RB carryover gaming state is increased, and the payout rate in the RB carryover gaming state is greatly improved compared to the BB general gaming state. Specifically, with the reel 9 stop control, in the RB carryover gaming state, the probability of winning a 13-card combination is 30 times or more compared to the BB general gaming state. For this reason, the payout rate in the BB general gaming state is less than 100% (about 17%), whereas the payout rate in the RB carryover gaming state is 100% or more (about 300%).

  In the RB carryover gaming state, it is difficult to win the RB combination as compared to a game in which the RB combination is won in the BB general gaming state. Specifically, in the RB carryover gaming state, the lottery values of the role lottery are not assigned to the loser and the bonus role, and in the role lottery, the general role is always won. That is, in the RB carryover gaming state, the game is played in a state where the general combination and the RB combination are won simultaneously. As described above, in the stop control of the reel 9, in order to prioritize the winning of the re-playing role and the small role over the bonus role, in the RB carryover gaming state, the RB role is related regardless of the operating procedure of the stop switch 7. The symbol combination can hardly be stopped and displayed on the active line.

  As shown in FIG. 11, in the RB carryover gaming state, if the winning group of SP_01, SP_02, SP_03 is won and one player (one player E) included in the winning group is missed, the reel The RB combination may be won by the stop control of 9. However, as described above, if the player operates the stop switch 7 corresponding to the left reel 9 at a timing at which “T2 (tomato B)” cannot be stopped on the active line, the player is in the winning state of the RB role. However, it is possible to reliably avoid winning the RB role. That is, in the RB carryover gaming state, regardless of the result of the role lottery, if the stop switch 7 is operated at an appropriate timing, the player can surely avoid the winning of the RB role and have a disadvantage in the payout rate. Transition to the RB gaming state can be avoided.

  In this way, in the BB gaming state, the RB combination is won in the BB general gaming state, but the RB gaming state that shifts by winning the RB combination is a gaming state in which the play rate is unfavorable. The RB carryover gaming state in which a role is missed and shifted is a gaming state in which the payout rate is advantageous. For this reason, in the BB gaming state, the player operates the stop switch 7 so as to miss the RB combination in the BB general gaming state, and aims to shift to the RB carryover gaming state. Further, even in the RB carryover game state, the game is played so as not to win the RB combination that has carried over the winning state.

  The BB gaming state is configured to end when the number of paid-out medals in the BB gaming state reaches a specified number, and shift to the normal gaming state. The prescribed number is set to 345 in the BB gaming state triggered by the first type BB combination winning, and 165 in the BB gaming state triggered by the second type BB winning combination. In addition, the three states established during the BB gaming state (the BB general gaming state, the RB gaming state, and the RB carryover gaming state) end with the end of the BB gaming state. When the RB carryover gaming state ends with the end of the BB gaming state, the winning state of the carrying over RB combination disappears at the end of the RB carryover gaming state.

  The BB carryover gaming state is a gaming state in which the BB role is won in the game lottery in the normal gaming state, but the BB role is not won in the game, and the game is executed by carrying over the winning state of the BB role. As shown in FIG. 10, the lottery probability of the winning combination lottery in the BB carryover gaming state is the same as that in the normal gaming state except that the lottery value of the bonus combination is distributed to the loser. In the BB carryover gaming state, in the stop control of the reel 9, it is easy to win a BB role that has carried over the winning state by increasing the frequency of making a specific small role (one-piece role C) a winning priority role.

  Specifically, as shown in FIG. 11, in the BB carryover gaming state, when the winning group of BE_01, 04, 09-12, AT_01-04 is won in the winning lottery, the timings included in the winning group are not limited. The winning combination is the timing combination (one-sheet combination C) included in the combination, not the combination (13-sheet combination or one-sheet combination D). Since this one-piece combination C is a timing combination, the symbols that do not constitute the symbol combination related to the one-piece combination C can be stopped and displayed on the active line according to the operation timing of the stop switch 7. Here, a single combination constituting a single combination C includes a plurality of combinations of symbols in which a combination of symbols of the BB combination and two symbols are common and one symbol is different. For example, for the BB combination of the symbol combination “R7-R7-R7”, the single combination C includes small combinations “R7-R7-MD” and “R7-MD-R7”. For this reason, in the BB carryover gaming state, when the single combination C is a winning priority combination, the first and second stop switches 7 can stop and display two symbols common to the single combination C and the BB combination. If the operation is performed at the timing, the two symbols are stopped and displayed on the active line by the stop control of the reel 9 that gives priority to the winning of the one-piece winning combination C, and the symbols relating to the BB winning combination are not missed. Two of the combinations can be stopped and displayed on the active line.

  Here, the two symbols common to the one-piece combination C and the BB combination are not included in the combination of symbols other than the one-piece combination C and the BB combination (such as the 13-piece combination and the one-piece combination D). As described above, when the two symbols common to the single combination C and the BB combination are stopped and displayed on the active line by operating the first and second stop switches 7, at that time, the single combination C and BB are displayed. It is impossible to win a prize for any other role. For this reason, if the player operates the last stop switch 7 at a timing at which one combination C is missed and the BB combination can be won, a combination of symbols of the BB combination is constituted by stop control of the reel 9. The third symbol is stopped and displayed on the active line, and the BB combination is won.

  As described above, in the BB carryover game state, when the winning group (BE_01, 04, 09-12, AT_01-04) having the single winning combination C as the winning winning combination is won, the symbols of the single winning combination C and the BB winning combination are selected. Operate the first and second stop switches 7 at a timing at which two symbols common to the combination can be stopped and displayed on the effective line, and further, the last stop switch 7 cannot win a single combination C, and By operating at the timing at which the BB combination can be won, the BB combination can be won. According to such a configuration, in the BB carryover gaming state, the occurrence frequency of games that can win the BB role increases. It becomes possible to shift to the BB gaming state. By controlling the reel 9 to stop, the payout rate in the BB carryover game state is improved as compared with the normal game state, but the playout rate in the BB carryover game state is suppressed to less than 100% (about 70%).

  As described above, in this embodiment, when the RB combination is won in the BB general gaming state, if the player avoids the winning of the RB combination, the player shifts to the RB carryover gaming state in which the payout rate is 100% or more. Thus, while avoiding the transition to the RB gaming state where the payout rate is disadvantageous, it is possible to enjoy the gaming state where the payout rate is advantageous. For this reason, in this embodiment, when the RB role is won, the player is not disappointed, but rather, by avoiding the winning of the RB role, the game state is shifted to an advantageous game state with an output rate. Because new game play is given, it is possible to realize an entertaining game that takes advantage of the unexpectedness of the RB game state with a payout rate of less than 100%. Furthermore, the game state (BB general game before the RB role winning) In the state and the RB carryover game state), the lottery probability of the small role in the role lottery is changed only by changing the winning priority of the 13-piece role and the one-sided role that are won simultaneously according to the presence or absence of the RB role. Therefore, it is possible to vary the payout rate, so that it is possible to give a clear appearance to the payout rate in each gaming state without increasing the data capacity related to the role lottery.

  In particular, in this embodiment, the RB role is a lottery drawing in the BB general gaming state, and is configured to win independently without winning simultaneously with other roles. When the RB role is won in the role lottery, the stop switch Before the player 7 is operated, the player is informed of the winning of the RB role by the image display 10, the speaker 11, and the effect lamp 12. In such a configuration, when the RB winning combination is won, the player can recognize that the stop switch 7 should be operated so as to avoid the winning of the RB winning. Therefore, by avoiding the winning of the bonus winning (RB winning) It is possible to improve the interest of the game by making the player strongly aware of the gameability of shifting to a game state with an advantageous game play rate.

  Also, in this embodiment, in the BB general gaming state and the RB carryover gaming state, several winning groups (BE_01, 03, 04, 06-13) that will be simultaneously elected to the 13th winning combination are elected. In the BB general gaming state, priority is given to winning a one-piece combination, and the reel 9 is stopped so as not to win a 13-piece combination regardless of the operation procedure of the stop switch 7, and in the RB carryover gaming state, Because the reel 9 is controlled so that the winning of 13 winning combinations is prioritized so that the winning of 1 winning combination is not made regardless of the operation procedure of the stop switch 7, the profit corresponding to each gaming state regardless of the skill of the player. Can be given to the player.

  In the present embodiment, the BB general gaming state, the RB carryover gaming state, and the RB gaming state are gaming states established during the BB gaming state. Therefore, first, the bonus combination (BB combination) is won, and then , It is possible to entertain the player in stages with a symmetric game of avoiding the winning of the bonus combination (RB combination) and shifting to a gaming state (RB carryover gaming state) with an advantageous payout rate. Become. Further, in this configuration, the RB carryover gaming state ends when the payout in the BB gaming state reaches a specified number, so that the player does not shift to the RB gaming state in which the payout rate is disadvantageous, and is in the BB gaming state. Can exclusively enjoy the RB carryover gaming state in which the payout rate is advantageous, and can also prevent the player from being given excessive profits due to the RB carryover gaming state being excessively continued.

  Further, in this embodiment, a bonus combination (BB combination and CB combination) that shifts to a bonus gaming state with a winning rate of 100% or more by winning, and a bonus combination that shifts to a bonus gaming state with a winning rate of less than 100% by winning. (RB role), and when the winning combination of the bonus role that shifts to the bonus game state with a payout rate of 100% or more is carried over, the game moves to the carryover game state with a payout rate of less than 100%, and the payout rate 100 If the winning combination of the bonus combination that shifts to a bonus gaming state of less than% is carried over, the player is transferred to the carryover gaming state with a payout rate of 100% or more. Enjoy two symmetrical games: a game that operates the stop switch 7 to win the CB role and a game that operates the stop switch 7 so that the bonus role (RB role) does not win. It becomes possible.

  In addition, as described above, in this embodiment, when a specific role group (BE_01, 04, 09-12, AT01-04) is won, in the BB carryover gaming state, when the stop switch 7 is operated at an appropriate timing, Since the reel 9 is controlled so that the BB role is won without winning the small role, even if the BB role is missed in the normal game state, it is easy to escape from the BB carryover game state where the play rate is disadvantageous. Thus, it is possible to shift to the BB gaming state in which the payout rate is advantageous. On the other hand, in the RB gaming state, when the same specific role group (BE_01, 04, 09-12, AT01-04) is won, the 13-time role or the 1-time role D, which is a timing-unrelated role, is selected as a winning priority role. Therefore, regardless of the operation procedure of the stop switch 7, since the small role (13-piece combination or 1-piece combination D) is won, it is difficult to win the RB role, and the RB carryover gaming state that has an advantageous game play rate It becomes easy to continue. As described above, in this embodiment, the stop control of the symmetrical reels 9 is performed in the carryover game state in which the payout rate is disadvantageous and the carryover game state in which the payout rate is advantageous. The control works favorably for the player in each gaming state, so that the player can enjoy the symmetrical reel 9 stop control mode in the two carryover gaming states. In particular, in the present embodiment, in two carryover game states, without changing the lottery probability of the small role, it is possible to change the two carryover game states into a game state that is easy to win a bonus combination. There is an advantage that it can be controlled to a gaming state that is difficult to win.

  Further, in this embodiment, in the normal gaming state where a bonus combination (BB combination and CB combination) that shifts to a bonus game state with a payout rate of 100% or more can be won, the game shifts to a bonus game state with a ball output rate of less than 100%. Bonus with a winning rate of 100% or more in the BB general gaming state that can be won for a bonus role (RB role) that does not win a bonus role (RB role) to be transferred to a bonus gaming state with an appearance rate of less than 100% It is configured not to win the bonus combination (BB combination and CB combination) that shifts to the gaming state, and according to the gaming state, it becomes possible to win a symmetric bonus combination with different taste, so that the player is in the gaming state It is possible to feel the excitement of the transition.

  In this embodiment, when the stop switch 7 corresponding to the left reel 9 is operated at a specific timing in the RB carryover gaming state, the left reel 9 forms a symbol combination of the RB combination regardless of the result of the combination lottery. Since the symbols not to be displayed are stopped on the active line, in the RB carryover gaming state, if the stop switch 7 corresponding to the left reel 9 is operated at a specific timing, the player can play the RB role. It is possible to avoid winning and continue the RB carryover gaming state with an advantageous payout rate.

If a winning group is won, one winning combination may be a winning priority combination. Further, in the above embodiment, the 13-piece combination is an unquestioned timing combination, and when the 13-piece combination becomes a winning priority combination, the 13-piece combination is always won, but the 13-piece combination is won. When priority is given, a missing piece may be generated, or when it is missed, a single winning combination may be won. Similarly, if priority is given to winning a 1-comb combination when winning simultaneously with a 1-player and 13-player, it may be possible not to miss it, or there may be a 13-player award if it is missed. Also good. Further, in the above embodiment, when the winning combination of 1 and 13 in the BB general gaming state lottery is won at the same time, depending on the winning group, the winning combination of 1 and the 13 winning combinations.
