  The present invention relates to a slot machine that rotates and stops a reel on which a plurality of symbols are displayed, and determines a game result by a combination of symbols at the time of stopping. In particular, a slot that plays a winning game that advances the game more advantageously for the player than the normal game when the winning combination is won by the control lottery by the control means, and the symbol corresponding to the winning winning combination stops and wins a prize About the machine.

  2. Description of the Related Art A slot machine in which a player inserts a game medium, rotates a reel on which a symbol is displayed, stops it, and determines a game result by a combination of symbols at the time of stop is widely used as one of the gaming machines. In this slot machine, a lottery is usually performed by the control means, and when a symbol corresponding to the winning combination in the lottery stops and a prize is won, processing corresponding to the winning combination is performed. Among the processes according to the winning combination, there are processing of paying out game media and winning games that advance the game more favorably for the player than normal games when winning the winning combination by winning the lottery. Processing to be performed is included. The winning game includes, for example, a big bonus (BB) and a regular bonus (RB).

Among the slot machines in which the winning game is set, for example, in order to increase the player's interest in the game, the RB game in the BB game has a condition (for example, executable) that is more advantageous than the RB game in the normal game. A slot machine in which the number of times, the limited number of winnings, and the winning probability are set) has been proposed. (For example, refer to Patent Document 1.)
JP 2002-191760 A

  In the slot machine proposed in Patent Document 1, the content of the RB game during the BB game is set differently from the content of the RB game during the normal game as described above, but the RB game is started in the BB game. The requirement is limited to the case where the RB combination is won in the combination lottery and the symbol corresponding to the RB combination is stopped as in the conventional case. Therefore, the novelty in the progress of the game is scarce, and if the game is played for a long time, the progress of the game becomes monotonous and it is difficult to maintain the player's interest in the game for a long time.

  Therefore, the object of the present invention is to solve the above-mentioned problems, and in a winning game, a new aspect can be set as a requirement to start another winning game, and the player's interest in the game can be increased and sustained. To provide a slot machine.

  In order to achieve the above object, as a slot machine according to the present invention, a slot machine capable of performing a game in which a process for rotating and stopping a plurality of reels displaying a plurality of symbols is performed once. A winning lottery means for performing a winning lottery for determining one winning combination by lottery from among winning winning combinations, a reel control means for controlling stop of the plurality of rotated reels, and the winning lottery means When winning a winning combination, refer to the result of the stop control, and if the symbol corresponding to the winning combination stops and wins, the winning game is performed to advance the game more advantageously for the player than the normal game. Game control means, and when there is a reel that has not stopped even after a predetermined time has elapsed since the start of rotation of the reel, the reel control means Automatic stop control is performed to stop the game without the player's stop operation, and the winning game includes winning game 1 and winning game 2. In the winning game 1, at least one of the reels is automatically stopped. It is conceivable to perform the winning game 2 by the winning game control means when stopped by control.

  Here, the “reel on which the symbol is displayed” includes a reel that is physically rotated and stopped by a motor or the like, and is displayed on the image display device and is displayed on the image that is rotated and stopped. Is also included.

  The “combination” includes at least a “winning role” for performing a “winning game” that advances the game in an advantageous manner for the player, a general role for paying out a predetermined number of game media when winning, and a game A “re-game player” for “re-game” that can re-execute the game without inserting a medium is included.

  “Winning” refers to performing “winning game” in which a game progresses in an advantageous manner for a player when a winning combination is won by lottery and a symbol corresponding to the winning role stops and wins a prize. It is a possible role. The winning combination includes a big bonus combination (hereinafter referred to as BB combination) and a regular bonus combination (hereinafter referred to as RB combination), and other arbitrary winning games can be set.

  The RB combination is a combination that shifts to an RB game that is one of the winning games. In this RB game, a game in which a predetermined combination is won with a high probability can be performed a predetermined number of times under a certain condition. In addition, the BB role is a role for shifting to a BB game that is one of the winning games. This BB game can be used for general games and can be transferred to RB games under certain conditions during the general games. This is a game in which a general game and an RB game can be repeated until a predetermined number of game media payouts is reached.

  The “general combination” is a combination in which a predetermined number of game media are paid out when a general combination is won by lottery and a symbol corresponding to the general combination is won.

  “Re-playing” means that when a re-playing role is won by lottery and the symbol corresponding to the re-playing role stops and wins, the next game can be executed without throwing in game media. (Also called replay).

  In the “lottery” for determining one combination, for example, it is desirable to generate a random number and determine one winning combination based on the value. Regarding the generation of random numbers, it is conceivable to use a random number generator or to generate them on software using a computer or the like.

  “The corresponding symbol has stopped” means that, for example, the symbols determined corresponding to the combination for each reel have stopped on a predetermined active line, and the winning symbols are aligned. For example, a BB game can be set as the “winning game 1”, and an RB game or a BB game can be set as the “winning game 2”, for example. In addition, when other winning games are set, it may be possible to set those winning games.

  “Performing a winning game” specifically means that a winning game is played from the next game when the winning symbol is won and the corresponding symbol stops. Specifically, “performing winning game 2” means that in winning game 1, when at least one reel is stopped by the automatic stop control, the winning game 2 is performed from the next game.

  “Automatic stop control” is one of the reel stop controls performed by the reel control means. Although reel stop control is possible based on the player's stop operation after the reel starts rotating, there are still reels that have not stopped even after a predetermined time set as the time limit has elapsed. At this time, all the reels that are not stopped are controlled to be stopped without the player's stop operation. As the symbol stop control of the reel by automatic stop control, stop control that stops a predetermined symbol is possible, stop control that does not stop a predetermined symbol is possible, and a reel is It can also be stopped. The reel symbol stop control by this automatic stop control is referred to as automatic symbol stop control in the following description.

  In the slot machine of this embodiment, the game can be started by “injecting” “game media”, and a predetermined number of game media can be paid out according to the game result. Here, the “game medium” is a medium inserted into the slot machine for playing a game, and for example, a coin, a medal, a chip, or the like can be considered. Moreover, as long as this object can be achieved, the product is not limited to an article, and for example, an electromagnetically acting material such as a magnetic card can be applied. In addition, “inserting” a game medium includes actually inserting a game medium from a game medium slot provided in the slot machine, or storing it in a storage medium of the slot machine. This includes using a predetermined number of game media credited in advance.

  According to the present embodiment, in the winning game 1, when at least one reel is stopped by the automatic stop control, the winning game 2 is set to be performed. This is different from the setting for winning a game when winning. Therefore, it can be expected that the player is given an unexpectedness in the progress of the game, and the player's interest in the game is increased and sustained.

  Further, as a slot machine according to the present invention, as a result of winning a predetermined combination in the winning game 1 in the combination lottery and at least one reel being stopped by the automatic stop control, the symbol corresponding to the combination is stopped. It is conceivable that the winning game 2 is performed by the winning game control means when no winning is made.

  As the “predetermined combination”, it is conceivable to set all combinations including a general combination and a replay combination, and it is possible to set a winning combination. According to the present embodiment, since the winning game 2 may or may not be performed depending on the result of the winning lottery or the stop control result including the automatic stop control, the progress of the game can be changed. is there. Therefore, it can be expected that the player's interest in the game is increased and sustained.

  As a slot machine according to the present invention, it is further conceivable that the reel is stopped by the automatic stop control so that the predetermined combination won in the combination lottery does not always win.

  According to this embodiment, when a predetermined combination is won by the combination lottery and at least one reel is stopped by the automatic stop control, the symbol corresponding to the predetermined combination selected is not stopped and the winning game 2 is performed. Can do. Therefore, the possibility of performing the hit game 2 that the player will be interested in increases, and it can be expected that the player's interest in the game is increased.

  According to the above-described invention, in the winning game 1, when at least one reel is stopped by the automatic stop control, the winning game 2 is set to be performed, and the symbol corresponding to the conventional winning combination is stopped. This is different from the setting for winning a game when winning. Therefore, it can be expected that the player is given an unexpectedness in the progress of the game, and the player's interest in the game is increased and sustained.

  Also, in the winning game 1, a setting for performing a winning game 2 is made when a predetermined winning combination is won by winning lottery and at least one reel is stopped by the automatic stop control, so that the symbol corresponding to the winning winning combination does not stop. Thus, depending on the result of the winning lottery or the result of the stop control including the automatic stop control, there are cases where the winning game 2 is performed and not performed, so that the progress of the game can be changed. Therefore, it can be expected that the player's interest in the game is increased and sustained.

  Further, as described above, in the sub control circuit 200, based on the signal received from the main control circuit 100, the control for image indication, the control for lighting the indication lamp, and the control for emitting sound are performed. Do. The image control means 510 can perform control processing for displaying a predetermined effect image on the image display device 70.

  In the control processing described below, the slot machine 10 is activated in advance, and variables used in the main control circuit 100 and the sub control circuit 200 described above are initialized to predetermined values and are in steady operation. To do.

<Description of main routine>
First, the control process of the main routine will be described with reference to the flowchart of FIG. In this main routine, a control process is performed when a game is performed once, in which one step from when a player inserts a game medium and when a plurality of reels with a plurality of symbols are rotated and stopped is performed once. Indicates.

  First, it is determined whether or not the value of the parameter NRP is greater than 0 (step S11). NRP is a parameter that determines whether or not to replay, and is set so that replay is performed when it is greater than 0, and replay is not performed when it is 0 or less. Further, as shown in step S167 of FIG. 14, when the re-gamer is won and won, 1 is input as the value of NRP.

  If it is determined in step 11 that the value of NRP is 0 or less (NO), it is determined that no re-game is performed, and then it is determined whether or not a game medium has been inserted (step). S12). When it is determined that a game medium has been inserted (YES), the process proceeds to step S15, and the inserted number counted by the game medium counter installed below the game medium insertion port 38 is detected as the bet number. However, when the number of game media exceeding the specified number (three in this embodiment) is inserted, the game media exceeding the specified number is stored in the RAM 110 as the number of credits.

  If it is determined in step S12 that no game medium is inserted (NO), the process proceeds to step S13, and it is determined whether there is a credited game medium. If it is determined that there is no credited game medium (NO), the process returns to step S12 again, and the determination processes of steps S12 and S13 are repeatedly executed.

  If it is determined in step S13 that there is a credited game medium (YES), it is next determined whether or not a bet operation signal has been received (step S14). This bet operation signal is transmitted when the player operates any one of the bet switches 32, 34 and 36. When it is determined that the bet operation signal has not been received (NO), the process returns to step S12 again, and the determination process from step S12 to step S14 is repeatedly executed. When it is determined that a bet signal has been received (YES), the number of bets is detected from the received bet operation signal (step S15). In either case of inserting a game medium or using a credited game medium, the detected bet number is stored in the RAM 110 as a new bet number, and when using a credited game medium, A process of subtracting the number of credits of the game medium by the number of detected bets is performed (step S16). Then, the process proceeds to a combination lottery processing subroutine (step S18).

  If it is determined in step S11 that the value of NRP is greater than 0 and the game is in a replaying state (YES), 0 is input to the value of NRP to cancel the replaying state (step S17), and step S12. Without proceeding to step S16, the process proceeds to the combination lottery processing subroutine (step S18). That is, when it is determined that the game is in the re-gaming state, the game can be performed without newly inserting a game medium or consuming the credited game medium. In addition, as the bet number in the re-game, the same bet number as the previous game can be set, or a bet number different from the previous game bet number can be used.

  In the combination lottery processing subroutine of step S18, combination lottery processing by the combination lottery means 410 is performed, and flag-on processing for turning on the RB flag, the BB flag, the replay flag, and the general combination flag is performed according to the winning combination. It is. Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Subsequent to the role lottery processing subroutine (step S18), on the basis of the result of the role lottery, the reel variation and stop subroutine (step S19) for performing control processing relating to the movement of the reels that are stopped after the reels 40L, 40C, 40R are rotated. ) Is performed. This reel fluctuation / stop subroutine is performed by the reel control means 440, and details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Next, after the reels are stopped by the reel fluctuation / stop subroutine, a winning symbol determination is performed, and based on the determination result, a winning determination and flag off processing subroutine (step S20) for performing flag-off processing is performed. Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Then, a payout process (step S21) for paying out a predetermined number of game media corresponding to the winning game based on the winning lottery and winning symbol determination is performed. In the payout process, it is possible to actually pay out the game media from the game media payout outlet 62, or to credit a predetermined number of game media instead of paying out. One game is completed by the above control process. By repeating the control process shown in this main routine, the player can play a plurality of times.

<Role lottery processing subroutine>
Next, the combination lottery processing subroutine performed in step S18 of the main routine will be described in detail with reference to the flowcharts shown in FIGS.

  First, it is determined whether or not the value of the parameter NRB is greater than 0 (step S31). The NRB is a parameter that determines whether or not to play an RB game. The NRB is set so as to play an RB game when it is larger than 0 and not to play an RB game when it is less than 0. In addition, when winning the RB combination shown in step S164 of FIG. 14 or winning the general combination 2 and not winning during the BB game shown in step S143 of FIG. Is to be input.

  If it is determined in step S31 that the NRB value is greater than 0 (YES), the RB lottery table stored in the ROM 108 is read (step S32), and the process proceeds to step S36. Here, an example of the RB lottery table is shown in FIG.

  In the RB lottery table, a winning combination of symbol number 1 and a symbol number 2 are set to be different, and in the case of winning combination, it is set to win when all three reels have JAC symbols. . In the winning lottery performed in step S36 described later, the probability that the winning combination is won is 1 / 1.01, which is set very high. Therefore, during the RB game, the possibility of winning a winning combination is high. Conversely, the probability of loss is set to about 1/100, and the possibility of loss is low.

  If it is determined in step S31 that the NRB value is 0 or less (NO), it is next determined whether or not the parameter NBB value is greater than 0 (step S33). NBB is a parameter that determines whether or not to play a BB game, and is set so that a BB game is played when it is larger than 0 and a BB game is not played when it is 0 or less. Further, as shown in step S164 of FIG. 14, when the BB combination is won and won, 1 is input as the value of NBB.

  If it is determined in step S33 that NBB is greater than 0 (YES), the general lottery table for BB operation stored in the ROM 108 is read (step S34), and the process proceeds to step S36. Here, an example of the general lottery table during BB operation is shown in FIG.

  The general lottery table during BB operation is a lottery table used when the BB game is in progress and not in the RB game. If the game is BB game and RB game, the RB lottery table shown in FIG. 15 is used. In the general lottery table at the time of BB operation, three types of general combinations of symbol numbers 1 to 3, an RB combination of symbol number 4 and a deviation of symbol number 5 are set. Here, in comparison with a general lottery table when BB is not operated (see FIG. 17), which will be described later, the general lottery table when BB is operated is set to have no re-game combination and BB combination.

  If the winning combination probability of the general combination 1 with symbol number 1 is 1/80 and the symbol of the first reel is cherry, the symbol of the remaining two reels will be won regardless of the symbol. It is set to be. The general combination 2 with symbol number 2 is set to win when the winning probability in the combination lottery is 1/5 and all three reels have the same bell symbol. Here, in this embodiment, as shown in step S143 of FIG. 13, in the BB game, when the general game 2 is won and no winning is made, 1 is input to the value of the NRB, and the next game Is set to play RB games. Details of the control process will be described later.

  The general combination 3 with symbol number 3 is set to win when the winning probability in the combination lottery is 1/100 and all three reels have the same watermelon symbol. The RB combination with symbol number 4 is set to win when the winning probability in the combination lottery is 1 / 7.3 and all three reels have replay symbols. In the BB non-operating general lottery table to be described later (see FIG. 17), the winning probability of the RB combination in the combination lottery is 1/600, and the probability of winning the RB combination is higher in the BB game than in the normal game. Is set. As described above, even when the general combination 2 (winning probability 1/5) is won and no winning is made, the RB gaming state is set, so the possibility that the RB gaming is performed in the BB gaming is further increased. ing. The probability of symbol number 5 losing in the role lottery is set to about 1 / 1.56.

  Next, when it is determined in step S33 that the value of NBB is 0 or less (NO), the BB non-operating general lottery table stored in the ROM 108 is read (step S35), and the process proceeds to step S36. . Here, an example of the general lottery table when the BB is not operated is shown in FIG.

  As already explained, the BB non-operating general lottery table is a lottery table used in the normal gaming state, and includes three general roles of symbol numbers 1 to 3, a re-playing role of symbol number 4, and symbol number 5 RB combination, symbol number 6 BB combination, and symbol number 7 are set off. The three types of general combinations of symbol numbers 1 to 3 have the same settings for the above-described general lottery table at the time of BB operation (see FIG. 16) and the winning probability and symbol settings in the combination lottery. The re-game combination with symbol number 4 is set to win when the winning probability in the combination lottery process is 1 / 7.3 and all three reels have the replay symbols.

  The RB role of symbol number 5 is set to win when the winning probability in the symbol lottery process is 1/600 and all three reels have the blue 7 symbol. The chance of winning a role is low. The BB combination with symbol number 6 is set to win when the winning probability in the combination lottery process is 1/300 and all three reels have the red 7 symbol. In addition, the probability in the extra lot drawing is set to about 1 / 1.57.

  As described above, after the lottery table corresponding to the state of the game is read out, the lottery for acquiring the random number and performing the lottery determination is performed (step S36). Specifically, random numbers generated by the random number generator 112 are extracted by the random number extraction means 420, and the random number determination means 430 compares the extracted random numbers with the read lottery table and determines the winning.

  Subsequently to FIG. 6, the process proceeds to FIG. 7, and it is determined whether or not the RB combination is won as a result of this determination (step S <b> 40). If it is determined that the RB combination is won (YES), the RB combination flag is turned on and stored in the RAM 110 (step S41), and the process proceeds to step S48.

  If it is determined in step S40 that the RB combination has not been won (NO), it is next determined whether or not the BB combination has been won (step S42). If it is determined in this determination that the BB combination is won by the combination lottery (YES), the BB combination flag is turned on and stored in the RAM 110 (step S43), and the process proceeds to step S48.

  If it is determined in step S42 that the BB combination is not won (NO), it is next determined whether or not the re-game combination is won (step S44). If it is determined in this determination that the re-game combination is won by the combination lottery (YES), the re-game flag is turned on and stored in the RAM 110 (step S45), and the process proceeds to step S48.

  If it is determined in step S44 that the re-playing combination is not won (NO), it is next determined whether or not the general combination is won (step S46). In this determination, if it is determined that the general combination is won by the combination lottery (YES), the general combination flag is turned on and stored in the RAM 110 (step S47), and the process proceeds to step S48. If it is determined in step S46 that the winning combination has not been won (NO), the flag on process is not performed and the process proceeds to step S48.

  After performing a series of processing relating to flag-on as described above, in step 48, the symbol number and control symbol data corresponding to the winning combination in the winning lottery are read from the ROM 108 and used for the reel fluctuation and stop subroutine described later. This data is stored in the RAM 110. The combination lottery processing subroutine is thus completed.

<Explanation of reel fluctuation / stop subroutine>
Next, in the main routine of FIG. 5, when the above-described combination lottery processing subroutine (step S18) is completed, a reel fluctuation and stop subroutine (step S19) is then performed. The reel fluctuation / stop subroutine will be described in detail with reference to the flowchart shown in FIG.

  First, the symbol number and control symbol data stored in step S48 of FIG. 7 are read (step S61). Then, it is determined whether or not a predetermined shortest time has elapsed (step S62). If it is determined in this determination that the shortest time has not elapsed (NO), the determination process in step S62 is repeatedly executed. That is, the rotation of the reel, which is the next process, cannot be started until the shortest time has elapsed. By this control, the number of games played in a certain time is controlled to be within a predetermined number.

  If it is determined in step S62 that the shortest time has elapsed (YES), a reel rotation start signal is transmitted based on the player's start switch operation (step S63). Based on this signal, the motor drive circuit 114 operates to start the rotation of the motors 80L, 80C, 80R, and the reels 40L, 40C, 40R start to rotate.

  Next, it is determined whether or not the reel that has started rotating is rotating at a constant speed (step S64). If it is determined in this determination that the reel has not yet rotated at a constant speed (NO), the determination process in step S64 is repeated. That is, the reel stop control, which is the next step, cannot be performed until the rotation of the reel reaches a constant speed.

  If it is determined in step S64 that the reel has been rotated at a constant speed (YES), it is next determined whether a reel stop signal has been received (step S65).

  The reel stop signal is transmitted when the player pushes any one of the stop switches 52L, 52C, 52R. For example, when the stop switch 52L for the first reel is pushed, stop control of the motor 80L that rotates the first reel 40L is performed. Similarly, when the stop switch 52C for the second reel is pushed, the stop control of the motor 80C for rotating the second reel 40C is performed, and the stop switch 52R for the third reel is pushed. In such a case, stop control of the motor 80R that rotates the third reel 40R is performed. If it is determined in step S65 that a reel stop signal has been received (YES), symbol combination control is performed (step S66). In the symbol combination control, based on the symbol number and the control symbol data read out in step S61, a maximum of four frames are slid and a predetermined symbol is stopped or not stopped within that range. The details of the control process will be omitted.

  If it is determined in step S65 that the reel stop signal has not been received (NO), the control proceeds to step S67 without performing control related to the stop. In step S67, it is determined whether all reels have stopped. If it is determined that all reels are stopped (YES), this subroutine is terminated.

  If it is determined that all reels are not stopped (NO), it is next determined whether or not the time limit has elapsed (step S68). If it is determined that the time limit has not been reached (NO), the process returns to step S65 again, and the processing from step S65 to step S68 is repeated. Thus, until all the reels stop or until the time limit elapses, the process of executing the corresponding reel symbol stop control subroutine is repeated each time the reel stop signal is received.

  If it is determined in step S68 that the time limit has passed (YES), and there is a reel that has not been stopped, an automatic symbol stop control subroutine that stops all the reels that have not been stopped (step S69). To do. The contents of this automatic symbol stop control subroutine will be described later. Thus, the reel fluctuation / stop subroutine ends.

<Description of symbol stop control subroutine>
Next, the automatic symbol stop control subroutine shown in step S69 of FIG. 8 will be described using the flowchart shown in FIG. In this subroutine, when there is a reel that has not stopped even after the time limit has elapsed, stop control is performed for all the reels that have not stopped.

  First, it is determined whether or not the value of NBB is greater than 0, that is, whether or not a BB game is being played (step S81). If it is determined in this determination that the value of NBB is greater than 0 (YES), that is, that the BB game is being played, it is next determined whether or not the flag of the general combination 2 is turned on (step) S82).

  In this determination, if it is determined that the flag for the general combination 2 is ON (YES), that is, the flag for the general combination 2 is ON during the BB game, the value of the reel number X is next set. 1 is input (step S83). Here, the correspondence between the reel number X and each reel is set so that X = 1 corresponds to the left reel 40L, X = 2 corresponds to the middle reel 40C, and X = 3 corresponds to the right reel 40R. ing.

  Then, it is determined whether or not the reel with reel number X is stopped (step S84). If it is determined that the reel is not stopped (NO), automatic symbol stop control is performed to stop the rotation of the reel of reel number X without being based on the reel stop signal by the player's operation (step S85). ). In this automatic symbol stop control, the stop position can be shifted up to a maximum of four symbols (four frames, maximum 190 msec in time), and the reels are kept so that the symbol bell does not stop on the effective line within that range. The stop control is performed. Then, the process proceeds to step S86. If it is determined in step S84 that the reel is stopped (YES), the process proceeds directly to step S86.

  In step S86, it is determined whether or not the reel number X is greater than 2. If it is determined in this determination that the value of X is 2 or less (NO), a process of adding 1 to the value of X is performed (step S87), the process returns to step S84, and the processes of steps S84 to S86 are repeated. As a result of this series of processing, if there is a reel that has not stopped even after the time limit has passed for the reels with reel numbers X = 1 to 3, automatic symbol stop control is performed so as not to stop the symbol bell.

  In the present embodiment, stop control for not stopping the symbol bell is performed for all reels that have not stopped even after the elapse of the time limit. However, the automatic symbol stop control according to the present invention is not limited to this embodiment. However, for example, with reference to the symbol of the stopped reel, stop control can be performed so that the symbol bell does not stop on at least one of the reels. Therefore, in this case, when it is determined that the symbol bell has not stopped in the already stopped reels, it may be considered not to perform stop control that does not stop the symbol bell for the remaining reels.

  If it is determined in step S86 that the value of the reel number X is greater than 2 (YES), this subroutine is terminated. If it is determined in step S81 that the NBB value is 0 or less (NO), that is, it is determined that the BB game is not being played, the process proceeds to step S88. Similarly, if it is determined in step S82 that the general combination 2 flag is not turned on (NO), the process proceeds to step S88.

  In step S88, when there are reels that have not stopped even after the time limit has elapsed, the reels are slid up to 4 frames so that the symbols (winning symbols) corresponding to the winning combination in the winning lottery do not stop. Stop control is performed and this subroutine is terminated.

<Description of Winning Determination and Flag Off Processing Subroutine>
In the main routine of FIG. 5, when the reel fluctuation / stop subroutine (step S19) is completed, a winning determination and flag-off process subroutine (step S20) is performed. The winning determination and flag off processing subroutine will be described in detail with reference to the flowchart shown in FIG.

  First, it is determined whether or not the game state is that the value of NRB is greater than 0 (whether or not an RB game is being played) (step S91). If it is determined in this determination that the value of NRB is greater than 0 (YES), an RB game processing subroutine (step S92) is performed, and this subroutine is terminated. A detailed description of the RB game processing subroutine will be described later.

  If it is determined in step S91 that the NRB value is 0 or less (NO), it is next determined whether or not the NBB value is greater than 0 (whether or not a BB game is being played). (Step S93). If it is determined in this determination that the NBB is (YES), a BB gaming process subroutine (step S94) is performed, and this subroutine is terminated. A detailed description of the BB game processing subroutine will be described later.

  If it is determined in step S93 that the NBB value is 0 or less (NO), it is next determined whether or not there is a winning combination (step S95). If it is determined that there is a winning combination (YES), a winning combination processing subroutine (step S96) is performed, and this subroutine is terminated. A detailed description of the winning combination processing subroutine will be described later.

  If it is determined in step S95 that there is no winning combination (NO), this subroutine is terminated as it is. Hereinafter, a detailed description of the subroutine shown in steps S92, S94, and S96 will be given.

<Description of processing subroutine during RB game>
First, a detailed description of the RB game processing subroutine (step S92) executed when it is determined in step 91 that the RB game is being performed will be described with reference to the flowchart shown in FIG.

  First, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S101). Next, the game count and the winning count are counted, the game count and winning count data are updated, and the updated data is stored in the RAM 110 (step S102). These data are used as the RB game end condition. When the number of games or the number of winnings reaches a predetermined number, the RB game is ended.

  Next, it is determined whether or not a BB game is being played (step S103). If it is determined in this determination that the BB game is being played (YES), that is, the BB game is being played in the RB game, the payout number is counted to update the payout number data, and the updated data is stored in the RAM 110. (Step S104). This data is used as a BB game end condition. When the payout number reaches a predetermined number, the BB game is ended.

  Next, it is determined whether or not the BB game end condition is achieved (step S105). In this determination, if it is determined that the BB game end condition is achieved (YES), 0 is input to the NBB value and the NRB value, that is, the BB game state and the RB game state are canceled. (Step S106), this subroutine is finished.

  If it is determined in step S105 that the BB end condition is not achieved (NO), it is next determined whether or not the RB end condition is achieved (step S107). If it is determined that the RB termination condition has been achieved (YES), 0 is input as the NRB value to cancel the RB gaming state (step S108), and this subroutine is terminated. However, in this case, since the BB game continues, the process of inputting 0 to the value of NBB is not performed. If it is determined in step 107 that the RB end condition has not been achieved (NO), this subroutine is ended without releasing the RB gaming state.

  Next, returning to the determination in step S103, when it is determined that the BB game is not being played (NO), that is, the RB game is being played in the normal game, it is next determined whether or not the RB end condition is achieved. (Step S109). If it is determined in this determination that the RB end condition is achieved (YES), 0 is input to the value of NRB to release the RB gaming state (step S110), and this subroutine is ended. If it is determined in step S109 that the RB termination condition has not been achieved (NO), this subroutine is terminated without releasing the RB gaming state.

<Description of processing subroutine during BB game>
Next, FIG. 12 shows a detailed explanation of the BB game processing subroutine (see step S94) executed when it is determined that the BB game is being played in step S93 in the winning determination and flag off processing subroutine (see FIG. 10). This will be described with reference to the flowchart shown. First, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S121).

  Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S122). If it is determined in this determination that no winning is made (NO), a general combination 2 determination processing subroutine (step S123) is performed, and the process proceeds to step S128. A detailed description of the general combination 2 determination processing subroutine will be described later.

  If it is determined in step S122 that there is a prize (YES), it is next determined whether or not the RB combination has won (step S124). If it is determined in this determination that the RB combination has won (YES), 1 is input to the NRB value to set the RB gaming state (step S125), and the RB flag is turned off (step S126). The process proceeds to step S128. By inputting 1 to the value of NRB, the RB game is played from the next game. For example, in the determination of step S31 in FIG. 6, it is determined that the RB game is in progress.

  If it is determined in step S124 that the RB combination has not won (NO), the general combination flag is turned off (step S127), and the process proceeds to step S128.

  Next, in step S128, the payout number is counted, the payout number data is updated, and the updated data is stored in the RAM 110. This data is used as a BB game end condition, and when the payout number reaches a predetermined number, the BB game is ended.

  Next, it is determined whether or not the BB game end condition has been achieved (step S129). If it is determined that the BB game end condition is achieved (YES), 0 is input to the value of NBB to release the BB game state (step S130), and this subroutine is ended.

  If it is determined in step S129 that the BB termination condition is not achieved (NO), the BB gaming state is not canceled and the present subroutine is terminated.

<General role 2 determination processing subroutine>
Next, in the description of the above-mentioned BB gaming process subroutine (see FIG. 12), FIG. 13 shows a detailed description of the general combination 2 determination process subroutine (see step S123) executed when it is determined that there is no winning. This is done using a flowchart.

  First, it is determined whether or not the flag for the general combination 2 is turned on (step S141). If it is determined that the flag for the general combination 2 is turned on (YES), step 142 is performed. Proceed to That is, when it is determined that the general combination 2 is won by the combination lottery and the flag of the general combination 2 is turned on, and it is determined that the symbol bells corresponding to the general combination 2 are not prepared, the process proceeds to step S142.

  In step S142, it is determined whether or not the reel is stopped by the automatic symbol stop control shown in step S85 of FIG. If it is determined in this determination that the automatic symbol stop control has stopped (YES), that is, at least one reel has been stopped by the automatic symbol stop control and the symbol bells are not aligned, the NRB value is set to 1. Is input to set the RB gaming state (step S143), and the process proceeds to step S144. By inputting 1 to the value of NRB, an RB game is played from the next game. For example, in the determination of step 31 in FIG. 6, it is determined that an RB game is in progress.

  If it is determined in step S142 that the automatic symbol stop control has not stopped (NO), that is, if it is determined that the player has stopped due to the player's stop operation, the RB gaming state is not set. Then, the process proceeds to step S144. That is, in the present embodiment, not the automatic symbol stop control, but the setting of the RB gaming state is not performed when all the reels are stopped by the player's stop operation and the symbol bells are not aligned.

  However, the present invention is not limited to the above-described embodiment. For example, it is possible to set the RB game to be performed when all the reels are stopped by the player's stop operation and the symbol bells are not aligned. It is. In addition, the combination that is a requirement for starting the RB gaming state is not limited to the general combination 2, and any combination including other general combinations can be set. Furthermore, it is also possible to set the RB game start requirement only when one of the reels is stopped by the automatic symbol stop control without relating the result of the combination lottery to the start requirement of the RB game state.

  In step S144, the general combination 2 flag is turned off, and this subroutine is terminated. If it is determined in step S141 that the flag of the general combination 2 is not turned on (NO), if other flags such as the general combination 1, 3 are turned on. The flag is turned off (step S145), and this subroutine is terminated.

<Explanation of the processing sub-routine at the time of winning>
Next, in the determination and flag-off processing subroutine (see FIG. 10), the detailed explanation of the winning combination processing subroutine (see step S96) executed when it is determined in step S95 that there is a winning combination is shown in the flowchart shown in FIG. To do.

  First, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S161). Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S162).

  If it is determined in this determination that a prize has been won (YES), it is next determined whether or not the BB combination or the RB combination has won (step S163). In this determination, if it is determined that the BB combination or RB combination has won (YES), 1 is input to the value of NBB or NRB in accordance with the winning combination, and the winning gaming state (BB or RB) is set. (Step S164). Then, the winning BB or RB flag is turned off (step S165), and this subroutine is terminated. By inputting 1 to the value of NBB or NRB, BB and RB games are performed from the next game. For example, in the determination of step S31 or step 33 in FIG. 6, it is determined that the game is BB or RB game.

  If it is determined in step S163 that neither the BB combination nor the RB combination has been won (NO), it is next determined whether or not the re-game combination has won (step S166). If it is determined in this determination that the re-gamer has won (YES), 1 is input to the value of NRP (step S167). By this process, a re-game is performed in the next game (see step S11 in FIG. 5). Then, the re-game flag is turned off. If the BB and RB flags are on, a flag carry-over process is performed (step S168), and this subroutine is terminated.

  If it is determined in step S166 that the re-gamer has not won (NO), the general combination flag is turned off. If the BB and RB flags are on, Carry over processing is performed (step S169), and this subroutine is terminated.

  Returning to the determination in step S162, if it is determined that there is no winning (NO), it is next determined whether or not the BB and RB flags are on (step S170). In this determination, if it is determined that the BB and RB flags are turned on (YES), carry-over processing of the BB and RB flags is performed, and the other flags (general combination, replay combination) are turned on. If so, the flag is turned off (step S171), and this subroutine is terminated.

  If it is determined in step S170 that the BB and RB flags are not turned on (NO), the flag-on flag (general combination, re-playing combination) is turned off (step S172). Exit the subroutine.

<Description of main routine (continued)>
As described above, the subroutine shown in steps S92, S94, and S96 ends, and the winning determination and flag off processing subroutine shown in FIG. 10 ends. Here, returning to the main routine of FIG. 5, the winning determination and flag-off process subroutine of step S20 is terminated, the payout process of step S21 is terminated, and this main routine is terminated. Thereby, the control process for performing a game in which one process from the time the symbol fluctuates until it stops is completed.

(Other embodiments)
In the above-described embodiment, in the BB game, the automatic symbol stop control is performed, and when the general combination 2 is won and no winning is set, the RB game is set. However, as a requirement for starting the RB game, The combination to be applied is not limited to the general combination 2, and other general combinations can be used. If a replay combination or other winning combination is set, the replay combination or other winning combination is possible. You can also apply roles. It is also possible to set the RB game start requirement only when one of the reels is stopped by the automatic symbol stop control without relating the result of the winning lottery to the RB game start requirement.

  In the above-described embodiment, in the BB game, the RB game is set to be performed even when the RB game is won and won, but an embodiment in which the RB game is not set in the BB game is also conceivable. Furthermore, the slot machine according to the present invention is not limited to the above-described embodiment, and includes various other embodiments.
