Description

  The present invention relates to a slot machine in which a player inserts a game medium, rotates a reel on which a symbol is displayed, stops the game, and determines a game result by a combination of symbols at the time of stoppage. In particular, the present invention relates to a slot machine having a function capable of replaying without inserting game media.

  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 the stop is widely used as one of the gaming machines. In this slot machine, usually, a lottery is performed by the control means, and when the symbol corresponding to the winning combination in the lottery stops and a prize is won, a game in a mode corresponding to the winning combination is performed. .

  Here, in this slot machine, a special combination and a re-playing combination are set as a combination, and when a special combination is won, a special game that allows a player to play a game more advantageous than the general gaming state is performed. In some cases, the player can play the next game without inserting a new game medium when winning the re-gamer.

Among the slot machines that can be replayed, in order to increase the player's interest in the game, there is also proposed a slot machine that increases the probability that a re-gamer will win by lottery when a predetermined condition is satisfied. Yes. (For example, refer to Patent Document 1.)
JP 2001-137430 A

  Here, in the slot machine proposed in Patent Document 1, it is set so that the probability that a re-gamer will win in the lottery is increased at the timing when a predetermined special game is finished, and the progress of the game is changed. Has also been proposed. In the proposed slot machine, after changing the game mode to a state where the winning probability of the re-gamer is high, the game after the change to the state where the winning probability of the re-gamer is high is returned at the timing of returning to the original game mode again. When a predetermined number of times are performed, the state where the winning probability of the re-gamer is high is canceled. As described above, there has been proposed a slot machine that is provided with a combination of start conditions for changing the game state to a re-game probability variation state in which the winning probability of the re-gamer is set to a different value. Furthermore, since the start condition for changing the game mode to the re-game probability variation state is limited to a certain condition such as after the end of the special game, it can be changed from the normal general game to the re-game probability variation state. I could not do it. However, if the game is continued for a long time, the game tends to be monotonous, and there is a problem that it is difficult for the player to continue the interest and freshness of the game for a long time.

  The present invention has been made in view of the above-mentioned problems, and when a re-playing combination is provided and a specific symbol combination is displayed on a reel, a predetermined start condition is achieved, It is possible to change the probability of winning the re-gamer to a re-game probability fluctuation state set to a different value. As a result, the game is not limited to games with a replay probability variation state that is limited to certain conditions such as after the end of a special game, but starts when a specific symbol combination is displayed on a reel even during normal general games. It is an object of the present invention to provide a slot machine that can be changed to a game with a replay probability variation state when the condition is achieved, and that the number of game media that can be acquired can be increased.

  Furthermore, even if a specific symbol combination is displayed on the reel in the game of the re-play probability variation state after the change has already been achieved and any one of the specific symbol combinations is displayed on the reel, the same If the start condition is satisfied, it is possible to continue the game in the replay probability variation state. On the other hand, if a different start condition is achieved, the game mode is changed to a new replay probability variation state. Make it possible. As a result, it is possible to switch the start condition between valid and invalid according to the state of the game, and by including game-related content, the slot machine that can continue the interest and freshness of the player for a long time Is to provide.

  In order to achieve the above object, in the slot machine according to the present invention, in a game in which the game state is a re-game probability variation state, any one of a plurality of specific symbol combinations is selected by the reel control means. Replay probability variation state control means capable of changing the game in the replay probability variation state under a predetermined condition when a specific symbol combination is displayed on the reel.

Specifically, the slot machine according to the present invention is:
A slot machine capable of performing a unit game until processing based on a result of rotating and stopping a plurality of reels displaying a plurality of symbols,
A role lottery means for determining which of the roles is won,
Reel control means for performing stop control of the plurality of rotated reels;
Game control means for proceeding with processing corresponding to the winning combination when winning the winning combination by the reel control means,
The game control means includes
Re-game control means for re-implementing a game without inserting a game medium when winning a winning re-game player;
When a specific symbol combination is displayed by the reel control means, predetermined as a starting condition was achieved, re-gaming probability change state status of the game, which is set the probability of replay combination is won different values To
A plurality of the specific symbol combination to achieve the predetermined start condition,
When any one of the plurality of specific symbol combinations is displayed, a replay probability variation state different from the replay probability variation state corresponding to at least one other specific symbol combination Change to
In the game that is changed to the replay probability variation state corresponding to the displayed specific symbol combination by displaying the one specific symbol combination among the plurality of specific symbol combinations , before SL even at least one other specific symbol combination is displayed, changing from the re-gaming probability change state modified by the specific symbol combination of the one is displayed in a different re-gaming probability change state And a re-game probability variation state control means for continuing the game in the current re-game probability variation state .

According to the above-described invention, when a specific symbol combination is displayed on the reels by the reel control means, assuming that a predetermined start condition is achieved, the game state is set to a different value for the probability that the re-gamer will win. Therefore, the game is not limited to the game in the replay probability variation state, which is limited to a certain condition such as after the end of the special game. Even during a general game, the start condition is achieved by displaying a specific symbol combination on the reel, and the game can be changed to a re-game probability variation state game, and the number of game media that can be acquired can be increased.

Further, the replay probability variation state control means has a plurality of specific symbol combinations displayed on the reel for achieving a predetermined start condition , and any one specific symbol combination among these specific symbol combinations. In the game of the re-play probability variation state after displaying, even if a specific symbol combination different from the above-mentioned specific symbol combination is displayed on the reel by the reel control means, As a result, the game is not changed to the replay probability fluctuation state that can be changed, and the game of the current replay probability change state is continued. Figure not only becomes possible, during the re-gaming probability change state game, other specific different from the specific symbol combination was to transition to the re-gaming probability change state Even combinations is displayed on the reel, without migrating to other replay probability change state, that enables to continue the game in the current re-gaming probability change state.

  As a result, according to the state of the game, it is possible to switch between valid and invalid regarding the game start condition in the re-game probability variation state after displaying a specific symbol combination, and to further include game content This makes it possible to continue the interest and freshness of the player for a long time.

  Here, the “game medium” is a medium that is inserted into the slot machine in order to play a game, such as coins, medals, and chips. 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.

  Further, 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 on the image that is rotated and stopped on the image. A reel is also included.

  “Position” includes a “general role” that pays out a predetermined number of game media when winning a prize, a “special role” that allows the game to proceed in an advantageous manner for the player, This includes “re-game” in which the game can be re-executed without inserting a medium.

  “Special game” means a game in which a game is advantageously advanced when a special symbol is won by a combination lottery means and a predetermined symbol corresponding to the special combination is stopped and won by a reel control unit. Say.

  The “special role” includes a “first special role” that can be transferred to a “first special game” in which a game in which a predetermined role is selected with a high probability by lottery is performed a predetermined number of times under a certain condition, A “second special role” that can be transferred to a “second special game” in which at least one of a game and a game corresponding to the first special game can be played is included.

  Here, the first special combination is a combination transferred to the first special game which is one of the special games, and includes a combination called a regular bonus combination (hereinafter referred to as an RB combination). In the first special 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. The second special combination is a combination that is transferred to the second special game, which is one of the special games, and includes a combination called a big bonus combination (hereinafter referred to as a BB combination). The second special game is a game in which at least one of the general game and the game corresponding to the first special game can be performed until a predetermined game medium payout number is reached.

  “Re-game” is a “re-game” that can be re-executed without throwing in game media when the game corresponding to the re-game player stops and wins a prize. It is a role that can be implemented.

  In the “lottery” for determining one combination or the “lottery” for determining the stop control mode, 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 phrase “predetermined symbols stop” includes a setting for stopping predetermined symbols for all reels, and also includes a setting for stopping predetermined symbols for some reels. In addition, the predetermined symbol can be set to the same symbol for all the reels, or a different symbol can be set for each reel.

  “Predetermined symbol does not stop” means that the requirement for corresponding to the above “predetermined symbol stops” is not satisfied. Therefore, for example, even when a predetermined symbol does not stop on some of the required reels, the “predetermined symbol does not stop”. Of course, even when the predetermined symbol does not stop on all the reels that are required, “the predetermined symbol does not stop”.

  Here, the “effective line” is one that has been activated from among the winning lines drawn by the player operating the bet switch among the plurality of winning lines drawn on the reel display window. It is a judgment target whether or not a combination of symbols stopped on the line has won a prize.

As the slot machine according to the present invention, the game control means includes special game control means for executing a special game that advantageously advances the game when the winning special role is won, and controls re-probability probability variation state control. If the means is determined to have achieved the predetermined start condition by winning the special combination, and the state is changed to the re-playing combination probability variation state, a different re-start is performed even if the start condition different from the start condition is achieved. It is preferable not to change to the game probability fluctuation state .

According to the invention described above, be changed when the special combination is won, the state of the game, the probability of replay combination is elected to re-gaming probability change state set to a different value. Then, after being changed to the re-gaming probability change state by a special role has been elected, further, even if achieving the other start conditions, without changing the current replay probability change state by that its it is possible to continue the game of re-gaming probability change state and that Do not.

Furthermore, the slot machine according to the present invention is a slot machine capable of performing a unit game until processing based on the result of rotating and stopping a plurality of reels on which a plurality of symbols are displayed,
A combination lottery means for determining which combination is won out of a combination including a plurality of re-playing combinations;
Reel control means for performing stop control of the plurality of rotated reels;
Game control means for proceeding with processing corresponding to the winning combination when winning the winning combination by the reel control means,
The game control means includes
Re-game control means for re-implementing a game without inserting a game medium when winning a winning re-game player;
When you achieve a predetermined first start condition, the state of the game, the first replay probability variation replay role one is set to a different value of the probability of winning from the plurality of replay role Change to the state,
In the game of the first re-gaming probability change state, further, when any one of the symbol combinations from a plurality of specific symbol combination is displayed by the reel control means, a predetermined second starting condition As a result, the game state is set to a different value for the probability that the game in the first replay probability variation state is terminated and another replay player is selected from the plurality of replay players. seen including a re-gaming probability change state control means, for changing the second re-gaming probability variation state of being,
The replay probability variation state control means is
In the game in the first replay probability variation state, when the specific symbol combination different from the second start condition is displayed, a predetermined third start condition is achieved. The third replay probability variation state in which the game in the replay probability variation state is terminated and the winning probabilities of the other replay actors in the first and second replay probability variation states are set to different values. To
In the game in the second replay probability variation state, even if the specific symbol combination that is the third start condition is displayed, the game in the second replay probability variation state is continued. It is characterized by.

According to the above-described invention, the game state is changed to the first re-game probability variation state in which the probability that one re-game player is selected from a plurality of re-game players is set to a different value, and the plurality of re-play games. The probability that another re-gamer is won from among the game players is changed to the second re-game probability variation state set to a different value, and the second re-game probability variation state is changed to the second re-game probability variation state. When a specific symbol combination different from the specific symbol combination to be changed to the replay probability variation state is displayed, the second replay probability variation state is changed to the third replay probability variation state. At this time, even if the different specific symbol combinations described above are displayed, the game is not changed to the third replay probability variation state, and the game in the second replay probability variation state is continued. Note that in the third replay probability variation state, the winning probabilities of the other replaying roles described above are different from the winning probabilities in the first and second replay probability variation states.

  In the slot machine according to the present invention, the predetermined first start condition is that the special game that makes the game proceed in an advantageous manner for the player is completed, and the predetermined second start condition is a plurality of specific symbol combinations. Of these, it is preferable that one re-playing role is displayed on the reel.

  According to the above-mentioned invention, immediately after the end of the special game, the game mode is changed to the first replay probability variation state, so that the winning probability of one regame player as the second start condition is re-established. By setting the game state higher than the game state of the general game that is not the game probability variation state, a game that can be easily changed to the second re-game probability variation state becomes possible.

  Furthermore, in a game in the first replay probability variation state after the end of the special game, which is the first start condition, the second replay game combination is displayed on the reel by displaying one replay combination from a plurality of specific symbol combinations. When the starting condition is satisfied, different starting conditions are always achieved, so that it is possible to expect an increase in the number of game media that can be acquired, and it is possible to continue the player's interest and freshness for a long time.

As a slot machine according to the present invention, the re-game probability variation state control means changes the game state to the first re-game probability variation state when the predetermined first start condition is achieved, The maximum number of games of the first replay probability variation state game is set as the end condition of the replay probability variation state game of the first replay probability variation state game. When the start condition is achieved, the game in the first replay probability variation state is terminated, the game state is changed to the second replay probability variation state, and the second replay probability variation state It is preferable to set the maximum number of games of the game in the second replay probability fluctuation state as the game end condition.

According to the above invention, when achieving the predetermined first start condition, the state of the game, as well as changes to the first re-gaming probability variation state of the first of the re-game probability change state gaming When the maximum number of games of the game in the first replay probability variation state is set as the end condition, and the predetermined second start condition is further achieved in the game in the first replay probability variation state, the first The game in the re-play probability variation state is terminated, the game state is changed to the second re-play probability variation state, and the second re-play probability variation state game is terminated as the second re-play probability variation state game. Since it is possible to set the maximum number of games in the game with the game probability variation state, in the game with the re-game probability variation state, the player is nervous to move to a more advantageous game until the predetermined number of games is reached. To keep playing and play games Kill.

  As a slot machine according to the present invention, the game end condition in the re-game probability variation state further includes winning a special role capable of shifting the game to a special game that favors the player. Is preferred.

  According to the above-described invention, as a result of winning the special role, it is possible not only to end the game in the re-game probability variation state but also to continuously set the game state in which the player is interested.

  According to the above-described invention, when a specific symbol combination is displayed on the reel by the reel control means, assuming that a predetermined start condition is achieved, the game mode is set to a different value for the probability that the re-gamer will win. Therefore, the game is not limited to the game in the replay probability variation state, which is limited to a certain condition such as after the end of the special game. Even during a general game, the start condition is achieved by displaying a specific symbol combination on the reel, and the game can be changed to a re-game probability variation state game, and the number of game media that can be acquired can be increased.

  Further, the replay probability variation state control means has already achieved a predetermined start condition, and in the game of the replay probability variation state after the change, any one particular symbol combination is selected from a plurality of specific symbol combinations. Even if displayed on the reel, if the same start condition is achieved, it is possible to continue the game in the re-game probability variation state, while if a different start condition is achieved, the game mode is renewed. It is possible to change to a replay probability fluctuation state. As a result, the start condition can be switched between valid and invalid according to the state of the game, and the game content of the game is included so that the player's interest and freshness can be continued for a long time.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this embodiment, as the start condition for changing to the replay probability fluctuation state, the start condition for changing to the replay probability change state when the BB game is ended, and the replaying player 2 shown in FIGS. When a specific symbol combination of a plurality of specific symbol combinations consisting of a combination 2 and a general combination 4 is displayed on a reel, a start condition for changing to a replay probability variation state is set as an end condition, and a replay probability variation Termination condition for ending the game in the replay probability variation state when the maximum number of games in the state is reached, and termination to terminate the game in the replay probability variation state when the special role RB role or BB role is won However, instead of adopting all start conditions and end conditions, it is possible to adopt some start conditions and end conditions, as well as other replays when winning a special role Stochastic fluctuation It is also possible that adopted the start conditions to change state.

  In the present specification, the terms “same start condition” and “different start conditions” are used for the start condition for changing the game mode to the replay probability variation state. Start condition for changing to the replay probability variation state when the BB game is ended, and start condition for changing to the replay probability variation state when one specific symbol combination among a plurality of specific symbol combinations is displayed on the reel In this embodiment, since the symbol combinations of the replay combination 2, the general combination 2 and the general combination 4 shown in FIGS. 17 to 19 are adopted as a plurality of specific symbol combinations in this embodiment, “the same start condition” "", For example, in the game of the replay probability variation state after the symbol combination of the replaying role 2 that is one of the specific symbol combinations is displayed on the reel, the symbol combination of the replaying role 2 is again displayed on the reel. It is not limited to the case where it is displayed, but includes the case where the symbol combination of general combination 2 or general combination 4 which is one of the specific symbol combinations is displayed on the reel. On the other hand, the “different start condition” means, for example, a replay game that is one of specific start symbol combinations other than the end of the BB game in the replay probability variation state game after the BB game is ended. The symbol combination of the combination 2, general combination 2 or general combination 4 is displayed on the reel.

These five winning lines include three horizontal (center L1, upper and lower L2A, L2B) winning lines and two diagonal winning lines (diagonally downward L3A, obliquely upward L3B). At the left end of these pay lines L1, L2A, L2B, L3A and L3B, bet number (number of bets) display sections 24a to 24e are "3", "2", "1", "2" in order from the top. , “3”. The bet number display sections 24a to 24e are a winning line (hereinafter referred to as an effective line) that is activated according to the number of inserted game media (in this embodiment, medals are used), and the number of bets on the game media. Is displayed.

  A substantially horizontal operation panel 30 is provided below the display windows 22L, 22C, and 22R. On the left side of the operation panel 30, a 1-bet switch 32, a 2-bet switch 34, and a maximum bet switch 36 are provided. In addition, on the right side of the operation panel 30, a game medium insertion port 38 through which a game medium can be inserted is provided.

  When a game medium is inserted from the game medium insertion port 38, the number of game media is counted by a game medium counter (not shown), and when a predetermined number or more of game media are input, The credit amount is stored in the RAM 110 described later.

  The 1-bet switch 32 is a switch for setting a game bet on only one of the credits. The 2-bet switch 34 is a switch for targeting only two of the credits for game betting. The maximum bet switch 36 is a switch for setting three medals out of the number of credits as a game bet.

  In the following, the number of game media to be bet is referred to as “the number of bets” and set as a bet object by the player by operating the 1-bet switch 32, the 2-bet switch 34 or the maximum bet switch 36 described above. The number of medals won is referred to as “set bet number”.

  When the player operates the 1-bet switch 32, one of the five winning lines, for example, the winning line L1 is activated. When the 2-bet switch 34 is operated, three of the five pay lines, for example, the pay lines L1, L2A, and L2B are activated. Further, when the maximum bet switch 36 is operated, all of the five pay lines, that is, L1, L2A, L2B, L3A and L3B are activated. The activated winning line is clearly indicated by lighting an effective line display lamp 124 (not shown) provided on the back of each of the bet number display units 24a to 24e.

The display device 70 is not limited to the above-described liquid crystal display panel, and any other image display device can be used as long as the player can visually recognize image information and text information during the game. The display device 70 can display a game history, an effect image in a special game, an effect image according to a lottery of a combination, an effect image according to the progress of the game, and the like.

  Inside the casing of the slot machine 10, three reels 40L, 40C, and 40R are rotatably provided. The reels 40L, 40C, and 40R have a ring shape, and a reel tape on which a pattern is printed is attached to the outer peripheral surfaces of the reels 40L, 40C, and 40R. For example, 21 symbols are arranged at equal intervals on each of the reels 40L, 40C, and 40R. The arrangement of these symbols is different for each of the reels 40L, 40C, and 40R. Each of these reels 40L, 40C, and 40R is provided so as to be visible through the display windows 22L, 22C, and 22R described above. When the reel is stopped, three consecutive symbols of one reel can be visually recognized in one display window. For this reason, a total of nine symbols can be visually recognized from all the three display windows 22L, 22C, and 22R.

  As will be described later, each of the reels 40L, 40C, and 40R is rotationally driven by a motor (not shown), and the symbols drawn on the outer peripheral surfaces of the reels 40L, 40C, and 40R in the display windows 22L, 22C, and 22R. Moves from top to bottom.

  A start switch 50 is tiltably provided on the left side of the front surface of the operation panel 30. Three stop switches 52L, 52C, and 52R are provided at the center of the front surface of the operation panel 30. The stop switch 52L corresponds to the left reel 40L, the stop switch 52C corresponds to the middle reel 40C, and the stop switch 52R corresponds to the right reel 40R.

  When the player tilts the start switch 50 described above, the three 40L, 40C, and 40R described above start to rotate all at once. When the three reels 40L, 40C, and 40R rotate, the symbols drawn on the outer peripheral surfaces of the reels 40L, 40C, and 40R are moved and displayed from the top to the bottom in each of the display windows 22L, 22C, and 22R. The

  When the rotational speeds of the three reels 40L, 40C, and 40R described above reach a constant speed, the operation of the stop switches 52L, 52C, and 52R by the player is effective.

  When the player pushes the stop switch 52L, the left reel 40L stops. When the player pushes the stop switch 52C, the middle reel 40C stops. When the player pushes the stop switch 52R, the right reel 40R stops.

  When the reels 40L, 40C or 40R are stopped, the three reels 40L, so that the symbols drawn on the outer peripheral surfaces of the reels are positioned on the winning lines L1, L2A, L2B, L3A and L3B described above. Each of 40C or 40R is controlled to stop.

  On the lower right side of the housing of the slot machine 10, sound is emitted from a speaker (not shown, corresponding to a speaker 64 shown in FIG. 4 described later) housed in the housing. A sound transmission hole 60 is provided for exiting to the outside. A game medium payout port 62 is provided at a central portion below the casing of the slot machine 10. When the reels 40L, 40C or 40R are stopped, the combination of symbols stopped and displayed on the active line becomes a predetermined combination, that is, a combination of symbols constituting a combination. A predetermined number of game media are paid out from the game media payout port 62.

  As described above, the game in the slot machine 10 is a game in which a game result is determined by a combination of symbols determined by the stopped positions of the stopped reels 40L, 40C, or 40R. This game is performed every time the player tilts the start switch 50, and the process from the start of rotation of the plurality of reels 40L, 40C or 40R to the stop of rotation can be repeated as one game. is there.

  The types of the above-mentioned combinations include, for example, general combinations, special combinations, and replay combinations. The “general combination” is a combination for paying out a predetermined number of game media. A “special role” is a “first special role” that can be transferred to a “first special game” in which a game in which a predetermined role is selected with a high probability by lottery is performed a predetermined number of times under a certain condition, This is a “second special role” that can be shifted to a “second special game” in which at least one of a game and a game corresponding to the first special game can be played. The “second special game” can be performed until at least one of the general game and the game corresponding to the first special game reaches a predetermined game medium payout number. In addition, the “Re-Gamer” can be selected for a game that has been played at the current game without newly introducing a game medium when winning the game by winning a lottery. This is a role that allows a replay (also called replay) with the number of bets maintained. Here, the number of replaying combinations is not necessarily limited to one, and in this embodiment, two replaying combinations of replaying combinations 1 and replaying combinations 2 are set.

<Description of Main Control Circuit 100>
The main control circuit 100 includes a role lottery means 410, a reel control means 420, and a game control means 430.

  The role lottery means 410 performs lottery of a role (a first special role and a second special role, which are special roles, a general role, and a replaying role) by a role lottery process. The role lottery means 410 includes, for example, a random number generator 412 (hard random number or the like) for a role lottery, a random number extraction means 414 for extracting a random number generated by the random number generator 412, and a random value extracted by the random number extraction means 414 And random number determination means 416 for determining the presence / absence of a winning combination and the winning combination based on The control processing by the role lottery means 410 is shown in the role lottery processing subroutine (see FIGS. 6 and 7).

  The reel control means 420 receives the reel rotation start signal transmitted from the start switch 50, thereby controlling the motors 80L, 80C, 80R to rotate the reels 40L, 40C, 40R, and the stop switch 52L. , 52C, and 52R, control is performed on the reel operation to stop the reels 40L, 40C, and 40R upon reception of a reel stop signal transmitted or a predetermined time. In the stop control, the symbol combination control is performed so that the stop symbols are aligned corresponding to the winning combination. The control processing by the reel control means 420 is shown in a reel fluctuation / stop subroutine (see FIG. 8).

  The game control means 430 wins the special combination, the general combination, and the re-playing combination in the combination lottery process, and when it is determined that the symbol corresponding to each combination is complete by the winning symbol determination regarding the stopped symbol, the winning combination Proceed with the process corresponding to. The game control means includes special game control means 432, re-game control means 434, and re-game probability variation state control means 436 in addition to paying out a predetermined number of game media.

  The special game control means 432 pays out a special game in which the game proceeds in an advantageous manner for the player or a predetermined number of game media. The re-game control means 434 performs control for re-implementing the game in a state where the number of bets in the game played immediately before is maintained without inserting the game medium. Then, the re-gaming probability fluctuation state control means 436 has a re-gaming probability fluctuation state in which, when a predetermined start condition is achieved, the game mode can be set to a different value for the probability that the re-game role is won by the role lottery means. (Hereinafter referred to as the RT (replay time) state), and after changing to the replay probability variation state, when a predetermined termination condition is achieved, a process of ending the game in the replay probability variation state is performed. The game in the re-game probability variation state is controlled.

Can produce sound.

(Description of control processing)
Hereinafter, various controls performed by the above-described control unit will be described in detail with reference to flowcharts.

  FIG. 5 shows a main routine of control processing performed by the main control circuit 100. 6 to 13 show subroutines that are control processes performed in the main routine.

  FIGS. 6 and 7 show a role lottery processing subroutine for performing a role lottery performed by the role lottery means 410 and a flag-on process performed following the role lottery. 8 and 9 show a reel fluctuation / stop subroutine in which the reel control means 420 performs control for rotating and stopping the reel. FIG. 10 shows a flag-off / RT setting processing subroutine which is a control process after the symbol is stopped by the reel fluctuation / stop subroutine.

  FIG. 11 shows an RB gaming process subroutine which is a part of the control process of the flag off / RT setting process subroutine, and FIG. 12 shows a BB game process which is a part of the control process of the flag off / RT setting process subroutine. FIG. 13 shows a winning combination processing subroutine which is a part of the flag off / RT setting processing subroutine.

  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. This main routine shows a control process when a unit game is performed once until a process based on a result of rotating and stopping a plurality of reels displaying a plurality of symbols.

  First, it is determined whether or not the re-gaming state is set and the re-gaming state is set (step S10). Note that the processing for setting the re-gaming state is performed in step S129 of the winning combination processing subroutine shown in FIG. 13, for example, as will be described later.

  When it is determined that the re-gaming state is not set (NO), based on a signal generated by the player operating the 1-bet switch 32, the 2-bet switch 34, or the maximum bet switch 36 described above, The set bet number is determined (step S11). This set bet number indicates the number of game media to be betted for one game. Furthermore, the set bet number is not limited to the number of game media that are betted after being temporarily accumulated as the credit amount described above, and the game that is inserted from the game media slot 38 and directly targeted for bet. Includes the number of media.

  When a game medium is inserted, the inserted number counted by the game medium counter installed below the game medium insertion port 38 is detected as the number of bets. 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. On the other hand, when it is determined that no game medium is inserted, the presence / absence of a credited game medium is determined. If there is no credited game medium, the set bet number cannot be determined in step S11. Further, when there is a credited game medium, it is determined whether or not a bet operation signal transmitted when the player operates any one of the bet switches 32, 34, or 36 is received, and the bet operation is performed. If the signal is not received, the set bet number cannot be set in step S11. On the other hand, if the bet operation signal is received, the bet number is detected from the received bet operation signal, and the game medium is inserted or credited. In any case of using a game medium, the detected bet number is stored in the RAM 110 as a new bet number. When a credited game medium is used, the detected bet is simultaneously determined from the credit number of the game medium. A process of reducing the number of sheets by a few minutes is performed.

  When it is determined in step S10 that the re-gaming state is set (YES), the re-gaming state setting is canceled (step S12), and a new game medium is inserted or the credited game medium is consumed. The game can be played again without playing. Further, since the bet number stored in the RAM 110 is used as the bet number in the re-game, the bet number of the game when the re-game player is won is used according to the bet number in the game performed immediately before.

  Next, it is determined whether or not the start switch 50 is turned on by the player (step S13). If it is determined that the start switch 50 is not turned on (NO), the process of step S13 is repeated. On the other hand, when it is determined that the start switch 50 has been turned on (YES), the routine proceeds to a role lottery processing subroutine (step S14).

  In the combination lottery processing subroutine of step S14, combination lottery processing is performed by the combination lottery means 410, and the RB flag, the BB flag, the corresponding replay flag, and the corresponding general combination flag are turned on according to the winning combination. Processing is performed. Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Subsequent to the winning lottery processing subroutine (step S14), based on the winning lottery result, a reel fluctuation / stop subroutine (step S15) for performing control processing relating to the movement of the reels that are stopped after the reels 40L, 40C, 40R are rotated is performed. It is. This reel fluctuation / stop subroutine is performed by the reel control means 420, 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 variation / stop subroutine, a winning symbol determination is performed, and a flag-off / RT setting processing subroutine (step S16) for performing a flag-off process based on the determination result is performed. Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Then, a payout process (step S17) of paying out a predetermined number of game media corresponding to the winning combination is performed based on the results of the winning lottery and winning symbol determination. In this payout process, it is possible to actually pay out game media from the game media payout outlet 62, but instead of paying out, it is also possible to credit a predetermined number of game media. The unit game is completed by the above control process. Then, by repeating the control process shown in this main routine, the player can play a plurality of unit games.

<Role lottery processing subroutine>
Next, the combination lottery processing subroutine performed in step S14 of the main routine will be described in detail with reference to the flowcharts shown in FIGS.

  First, it is determined from the NRT flag whether or not it is in the RT state. Here, the NRT flag is a flag for determining whether or not the RT state is set. When NRT = 0, the initial value is selected, and when NRT = RT1 to RT3, the special role (BB role, RB role) is won. In a game in a game state that is not a special game (BB game, RB game) and represents a RT state after a specific symbol combination is displayed on the reel, specifically, In the case of NRT = RT1, the RT state after the replaying game 2 is displayed, in the case of NRT = RT2, the RT state after the display of the general role 2 is displayed, and in the case of NRT = RT3, the RT state after the display of the general role 4 is displayed. Is. Further, when NRT = RT4, it represents the RT state after the end of the BB game.

  First, it is determined whether or not the NRT flag is set to RT1 (step S21). When it is determined in step S21 that the NRT flag is set to RT1 (YES), the lottery table is read after the specific symbol display (RT1) stored in the ROM 108 (step S22). Here, FIG. 17 shows an example of the lottery table after the specific symbol display (RT1).

  After the specific symbol display (RT1), in the lottery table, the BB role of symbol number 1, the RB role of symbol number 2, the general role of symbol numbers 3 to 6, the re-playing role of symbol numbers 7 to 8, and the symbol number 9 For example, when a general combination 2 is won, a prize is set when a bell is placed on the first and second reels and a replay symbol is placed on the third reel. In addition, when compared with the general lottery table when the BB is not activated (FIG. 16) used in the normal gaming state that is not the RB gaming state, the BB gaming state, the re-gaming state, and the RT gaming state, the winning probability of the re-game player 1 is 1. /1.2 is set to a very high probability, while the winning probability of re-playing combination 2 is set to a very low probability of 1/65536. Therefore, during the RT (RT1) game after the display of a specific symbol combination, the possibility of winning the re-player 1 is extremely high compared to during the general game, and the player plays a game different from the general game. You can feel it. Further, during the general game, when the re-game 2 is displayed on the reel by the reel control means as a specific symbol, it is changed to RT (RT1) game, and according to FIG. The maximum number of RT games (100 times) is set. Therefore, when the RT (RT1) game after the display of the replaying player 2 that is the specific symbol combination is performed 100 times, the RT (RT1) game after the specific symbol display is ended, and the game state returns to the general game state. . In addition, when 100 re-games after the display of re-playing role 2 that is a specific symbol combination, re-playing role 2 or other specific symbol combination (general role 2, general role 4) is displayed, The same start condition is achieved, and the game is continued without changing the RT game without newly resetting the RT game count. On the other hand, when another different start condition is achieved, the game mode is changed to a game in a different RT state.

  Then, after the specific symbol display (RT1), the lottery table is read, and then a lottery is performed in which a random number is acquired and a lottery determination is performed (step S23). Specifically, the random number generated by the random number generator 412 is extracted by the random number extraction means 414, and the random number determination means 416 compares the extracted random number with the read lottery table and determines the winning.

  If it is determined in step S21 that the NRT flag is not RT1 (NO), it is next determined whether or not the NRT flag is set to RT2 (step S24). When it is determined that the NRT flag is set to RT2 (YES), the lottery table is read after the specific symbol display (RT2) stored in the ROM 108 (step S25). Here, an example of the lottery table after the specific symbol display (RT2) is shown in FIG.

  After the specific symbol display (RT2), in the lottery table, the BB role of symbol number 1, the RB role of symbol number 2, the general role of symbol numbers 3 to 6, the re-playing role of symbol numbers 7 to 8, and the symbol number 9 Is set to be off. Further, compared with the general lottery table when the BB is not activated (FIG. 16), the winning probability of the replaying combination 1 is not changed, but the winning probability of the replaying combination 2 is set to 1/32768 which is considerably low. Therefore, during the RT (RT2) game after the specific symbol is displayed, the possibility of winning the re-gamer 2 is considerably lower than during the general game. Furthermore, in the general game, when the general combination 2 is displayed on the reel by the reel control means as a specific symbol, it is changed to RT (RT2) game, and according to FIG. The maximum number of RT games (20 times) is set. Therefore, when the RT (RT2) game after the display of the general combination 2 which is the specific symbol combination is performed 20 times, the RT (RT2) game after the display of the specific symbol is finished, and the game state returns to the general game state. Also, if 20 general RTs or 2 other specific symbol combinations (re-game 2 and general 4) are displayed during 20 RT games after the display of general 2 which is a specific symbol combination, the same Thus, the game is continued without changing the RT state game without resetting the number of RT games newly. On the other hand, when another different start condition is achieved, the game mode is changed to a game in a different RT state.

  If it is determined in step S24 that the NRT flag is not RT2 (NO), it is next determined whether or not the NRT flag is set to RT3 (step S26). When it is determined that the NRT flag is set to RT3 (YES), the lottery table is read after the specific symbol display (RT3) stored in the ROM 108 (step S27). Here, FIG. 19 shows an example of the lottery table after the specific symbol display (RT3).

  After the specific symbol display (RT3), in the lottery table, the BB role of symbol number 1, the RB role of symbol number 2, the general role of symbol numbers 3 to 6, the re-playing role of symbol numbers 7 to 8, and the symbol number 9 Outliers are set. In addition, when compared with the general lottery table when BB is not activated (FIG. 16), the winning probability of the re-gamer 1 is not changed to 1 / 7.3, but the winning probability of the re-gamer 2 is displayed after the specific symbol is displayed (RT2 ) Although it is slightly higher than the lottery table (FIG. 18), it is set to a very low value of 1/21845. Therefore, even during the RT (RT3) game after displaying the specific symbol, the possibility of winning the re-gamer 2 is extremely low compared to during the general game. Furthermore, during the general game, when the general role 4 is displayed on the reel by the reel control means as a specific symbol, it is changed to RT (RT3) game, and according to FIG. The maximum number of RT games (1000) is set. Therefore, when the RT (RT3) game after the display of the general combination 4 which is the specific symbol combination is performed 1000 times, the RT (RT3) game after the specific symbol display is ended, and the game state returns to the general game state. In addition, when the general combination 4 or other specific symbol combination (re-playing combination 2, general combination 2) is displayed during 1000 RT games after the display of the general combination 4, which is a specific symbol combination, the same Thus, the game is continued without changing the RT state game without resetting the number of RT games newly. On the other hand, when another different start condition is achieved, the game mode is changed to a game in a different RT state.

  If it is determined in step S26 that the NRT flag is not RT3 (NO), it is next determined whether or not the NRT flag is set to RT4 (step S28). If it is determined that the NRT flag is set to RT4 (YES), the lottery table is read after BB (RT4) stored in the ROM 108 (step S29). Here, FIG. 20 shows an example of a lottery table after the end of BB (RT4).

  After the completion of BB (RT4), in the lottery table, the BB role of symbol number 1, the RB role of symbol number 2, the general role of symbol numbers 3 to 6, the re-playing role of symbol numbers 7 to 8, and the difference of symbol number 9 And are set. In addition, when compared with the general lottery table when BB is not activated (FIG. 16), the winning probability of the re-gamer 1 is not changed to 1 / 7.3, but the winning probability of the re-gamer 2 is slightly lower to 1/25. Is set to a value. Further, when compared with the lottery table after the specific symbol display (RT1 to RT3), the maximum number of RT games is set for each of the specific symbol combinations that are the RT game start conditions whose NRT flag is RT1 to RT3. Therefore, when one specific symbol combination among a plurality of specific symbol combinations is displayed on the reel, it is assumed that the RT game start condition of any of RT1 to RT3 is achieved and the game mode is set to RT The game can be changed to a game, and the corresponding maximum number of RT games can be set as an end condition. Further, in the RT game after the end of the BB, the end condition based on the maximum number of RT games is not set. Therefore, the RT game after the end of the BB does not end depending on the maximum number of RT games, but the specific symbol combination (re-playing combination 2, general combination 2, general combination 4) is displayed during the RT game after the end of the BB. If this is the case, a different start condition has been achieved, and the RT game count is newly reset to change the game mode to a game in a different RT state.

  Although not set in the present embodiment, the maximum number of RT games can be set as an end condition in the RT (RT4) game after the end of the BB. As a result, immediately after the end of the BB game, the game is changed to RT (RT4) game immediately, so that the player can continue to play with a sense of tension to move to a more advantageous game until the player reaches the maximum number of RT games. It becomes possible to make it.

  If it is determined in step S28 that the NRT flag is not RT4 (NO), it is next determined whether or not the game mode is an RB game (step S30). When it is determined that the game mode is RB game (YES), the RB lottery table stored in the ROM 108 is read (step S31). Here, an example of the RB lottery table is shown in FIG.

  In the RB lottery table, the general combination of symbol numbers 1 to 4 and the divergence of symbol number 5 are set. For example, in the case of general combination 2, the first and second reels are bells, the third reels are It is set to win when the replay symbols are complete. In the combination lottery performed in step S23 described later, the probability that the general combination 2 wins is 1 / 1.04, which is set very high. Therefore, during the RB game, the possibility of winning the general combination 2 is very high. Conversely, the probability of loss is about 1/65536, which is set very low.

  If it is determined in step S30 that the game mode is not RB game (NO), it is next determined whether or not the game mode is BB game (step S32). When it is determined that the game mode is BB game (YES), the lottery table for BB operation stored in the ROM 108 is read (step S33). Here, FIG. 15 shows an example of the BB operation lottery table.

  The BB operating lottery table is a lottery table used when the game mode is in the BB game and not in the RB game. In the BB operation lottery table, an RB combination of symbol number 1, four general combinations of symbol numbers 2 to 5, and a deviation of symbol number 6 are set. Here, in comparison with the general lottery table when the BB is not operating (see FIG. 16, details will be described later), the BB operating lottery table is set so that there is no BB combination and replay combination.

  The RB combination of symbol number 1 is set to win when the winning probability in the combination lottery is 1/4 and the symbols of BAR are aligned on all three reels. In the BB non-operating general lottery table used in the normal gaming state (see FIG. 16), the winning probability of the RB role in the role lottery is 1/500, and in the BB game, the RB role is won compared to the normal time. The probability is set very high.

  Further, the general combination 1 with the symbol number 2 is set to win when the winning probability in the combination lottery is 1/100 and the three reels have the same watermelon symbol. The general combination 2 with symbol number 3 is set to win if the winning probability in the combination lottery is 1/10, the bell symbols are aligned on the left and center reels, and the replay symbols are aligned on the right reel. ing. For the general combination 3 with symbol number 4, if the winning probability in the combination lottery is 1/100 and the symbol of the first reel is cherry, the symbol of the remaining reels will be won regardless of the symbol. It is set to be. For the general combination 4 with symbol number 5, the winning probability in the combination lottery is 1/50, the symbol of the first reel is bell, the symbol of the second reel is replayed, and the symbol of the third reel is aligned with stars. The case is set to win.

  If it is determined in step S32 that the BB game is not in progress (NO), the general lottery table when the BB is not operating stored in the ROM 108 is read (step S34). An example of the general lottery table when BB is not operating is shown in FIG.

  The BB non-operating general lottery table is a lottery table used in a special game (RB game, BB game) and a normal game state that is not in the RT state. The BB role of symbol number 1, the RB role of symbol number 2, and the symbol Two replaying combinations, that is, a general combination of numbers 3 to 6, a replaying combination 1 of symbol number 7 and a replaying combination 2 of symbol number 8, and a deviation of symbol number 9 are set.

  For the BB combination of symbol number 1, the winning probability and symbol combination in the combination lottery are set. Furthermore, in the BB non-operating general lottery table of FIG. 16, 451 maximum acquired number is set as the end condition. In addition, the probability in the extra lot drawing is set to about 1 / 1.50.

  As described above, after the lottery table corresponding to the state of the game is read out, the role lottery for acquiring the random number and performing the lottery determination is performed (step S23).

  Then, as a determination result, it is determined whether or not the RB combination is won (step S35). When it is determined that the RB combination is won (YES), the RB flag is set to ON (step S36), and it is determined whether or not the NRT flag is 0 (step S37). When it is determined that the NRT flag is 0 (YES), it is not necessary to change to the RT game because the RT game is not performed, and the process proceeds to step S38 as it is and is stored in the RAM 110 (step S38).

  If it is determined in step S37 that the NRT flag is not 0 (NO), that is, it is determined that the RT game is in progress, since the RB role, which is a special role, is won, the RT game count is set to end the RT game. Reset and set the NRT flag to 0 (step S39). Then, the process proceeds to step S38. Thereby, the general game using the general lottery table when the BB is not operated can be performed from the next game.

  If it is determined in step S35 that the RB combination is not won (NO), it is next determined whether or not the BB combination is won (step S40). When it is determined that the BB combination is won (YES) by the combination lottery, the BB flag is set to ON (step S41). Then, it is determined whether or not the NRT flag is 0 (step S37). When it is determined that the NRT flag is 0 (YES), it is not necessary to change to the RT game because the RT game is not performed, and the process proceeds to step S38 as it is and is stored in the RAM 110 (step S38).

  If it is determined in step S37 that the NRT flag is not 0 (NO), since the special combination BB is won, the RT game count is reset and the NRT flag is set to 0 to end the RT game. (Step S39). Then, the process proceeds to step S38. Thereby, the general game using the general lottery table when the BB is not operated can be performed from the next game.

  If it is determined in step S40 that the BB role is not won (NO), it is determined whether or not any of the general roles 1, general role 2, general role 3, or general role 4 is won. Judgment is made (step S42). When it is determined that one of the general roles 1 is won (YES), the corresponding general role flag is set to ON (step S43), the process proceeds to step S38, and is stored in the RAM 110 (step). S38).

  Next, when it is determined in step S42 that none of the general combinations has been won (NO), it is determined whether or not re-game 1 or re-game 2 has been won (step S44). If it is determined that one of the re-game players has been won by the role lottery (YES), the corresponding re-game flag is turned on (step S45), the process proceeds to step S38, and is stored in the RAM 110 (step S38).

  Furthermore, if it is determined in step S44 that no re-playing role has been won (NO), any of the general role 1, the general role 2, the general role 3, and the general role 4 in the RB game is selected. It is determined whether or not the general combination is won (step S46). When it is determined that one of the general roles in the RB game is won (YES), the corresponding general role flag in the RB game is turned on (step S47), the process proceeds to step S38, and is stored in the RAM 110 (step S38). .

  Here, if it is determined in step S46 that any of the general combination 1, general combination 2, general combination 3, or general combination 4 in the corresponding RB game is not won (NO), the flag is turned on. Without performing the process, the process proceeds to step S38.

  As described above, after performing a series of processes related to flag ON, in step S38, the symbol number and control symbol data corresponding to the winning combination in the winning lottery are read from the ROM 108 and used in a reel fluctuation / 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 combination lottery processing subroutine (step S14) is completed, a reel fluctuation / stop subroutine (step S15) is then performed. The reel fluctuation / stop subroutine will be described in detail with reference to the flowcharts shown in FIGS.

  First, the symbol number and control symbol data stored in step S38 of FIG. 7 are read (step S51). Then, it is determined whether or not a predetermined shortest time has elapsed (step S52). When it is determined that the shortest time has not elapsed (NO), the determination process in step S52 is repeatedly executed. As a result, 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.

  When it is determined that the shortest time has elapsed (YES), a reel rotation start signal is transmitted (step S53). 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 S54). When it is determined that the rotation of the reel has not yet reached a constant speed (NO), the determination process in step S54 is repeated. As a result, the reel stop control as the next step cannot be performed until the rotation of the reel reaches a constant speed.

  If it is determined that the reel is rotating at a constant speed (YES), it is next determined whether or not a reel stop signal has been received (steps S55 to S57).

  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, a first reel stop signal is transmitted, and stop control of the motor 40L that rotates the first reel 40L is performed. Similarly, when the stop switch 52C for the second reel is pushed, a second reel stop signal is transmitted, and the stop control of the motor 40C for rotating the second reel 40C is performed, so that the third reel is controlled. When the stop switch 52R is pushed, a third reel stop signal is transmitted, and stop control of the motor 40R that rotates the third reel 40R is performed.

  When it is determined that none of the first reel stop signal, the second reel stop signal, or the third reel stop signal is received, the control relating to the stop is not performed, but the first reel stop signal, the second reel stop signal, or the third reel stop signal is not performed. When it is determined that any one of the reel stop signals has been received, the process proceeds to the next step S58.

  In step S58, it is determined whether or not there is a winning combination. If it is determined that there is a winning combination (YES), it is determined whether or not there is a symbol corresponding to the winning combination in the reel stoppable range ( Step S59). When it is determined that there is a symbol corresponding to the winning combination in the reel stoppable range (YES), the symbol corresponding to the winning combination is stopped on the active line (step S60), and the process proceeds to step S62.

  If it is determined in step S59 that there is no symbol corresponding to the winning combination in the reel stop possible range (NO), the reel is stopped so that symbols other than the symbol corresponding to the winning combination are stopped on the effective line. (Step S61), and then the process proceeds to Step S62.

  If it is determined in step S58 that there is no winning combination (NO), reel stop control is performed so that all winning combinations do not win, and the process proceeds to step S62.

  In step S62, it is determined whether or not all the reels are stopped. If it is determined that all the reels are not stopped (NO), the process returns to step S55 and is repeated until all the reels are stopped. On the other hand, when it is determined that all the reels are stopped (YES), it is determined whether or not the BB flag is set to ON (step S63).

  If it is determined in step S63 that the BB flag is set to ON (YES), a predetermined specific symbol is displayed on the reel because the game mode is a game inside the BB after winning the BB role. However, since it is not changed to RT game, this subroutine is finished as it is. On the other hand, when it is determined in step S63 that the BB flag is not set to ON (NO), NRT is used to determine whether or not the RT (RT1 to RT3) game after display of the specific symbol combination is being played. It is determined whether or not the flag is 0 or RT4 (step S64).

  In step S64, when it is determined that the NRT flag is not set to 0 or RT4 (NO), that is, the NRT flag is RT1, RT2 or RT3, RT after displaying a predetermined specific symbol (RT1 to RT3). Since the game is in progress, even if a specific symbol combination is displayed on the reel again during the RT (RT1-RT3) game, it will not be changed to a new RT game, and the existing RT game will be continued. Therefore, this subroutine is finished as it is.

  On the other hand, when it is determined in step S64 that the NRT flag is set to 0 or RT4 (YES), it is determined by the reel control means whether or not the symbol combination of the re-gamer 2 is displayed on the reel ( Step S65). In step S65, when it is determined that the re-game player 2 is displayed (YES), the NRT flag is set to RT1, the RT game number is reset, and the maximum RT game number (100 times) is set ( Step S66), this subroutine is terminated. As a result, it is possible to perform an RT (RT1) game after displaying a specific symbol with the maximum number of RT games (100) as the end condition from the next game.

  If it is determined in step S65 that the re-playing combination 2 is not displayed (NO), the reel control means determines whether or not the symbol combination of the general combination 2 is displayed on the reel (step S67). When it is determined in step S67 that the general combination 2 is displayed (YES), the NRT flag is set to RT2, the RT game number is reset, and the maximum RT game number (20 times) is set (step) (S68), this subroutine is terminated. As a result, it is possible to perform an RT (RT2) game after displaying a specific symbol with the maximum number of RT games (20 times) as an end condition from the next game.

  If it is determined in step S67 that the general combination 2 is not displayed (NO), the reel control means determines whether or not the symbol combination of the general combination 4 is displayed on the reel (step S69). If it is determined in step S69 that the general combination 4 is displayed (YES), the NRT flag is set to RT3, the RT game number is reset, and the maximum RT game number (1000 times) is set (step) S70), this subroutine is terminated. As a result, it is possible to perform an RT (RT3) game after displaying a specific symbol with the maximum number of RT games (1000) as the end condition from the next game. On the other hand, if it is determined in step S69 that the general combination 4 is not displayed (NO), this subroutine is terminated as it is.

  As a result, regardless of whether or not it is a winning combination, one specific symbol combination is displayed on the reel from among a plurality of specific symbol combinations consisting of the replaying role 2, the general role 2, and the general role 4. The game mode is changed to the RT (RT1-RT3) game after the specific symbol display, and the RT game after the specific symbol combination display after the change Even if any one of a plurality of specific symbol combinations is displayed on the reel by the reel control means, it is possible to continue the existing RT game without changing the game mode. It becomes.

  Furthermore, assuming that any one of the plurality of specific symbol combinations is displayed on the reel and the start condition is achieved, the game mode is changed to the RT (RT1-RT3) game after the specific symbol display. In the RT (RT1 to RT3) game in which the maximum number of RT games is set as the end condition of the RT (RT1 to RT3) game, the specific symbol combination is further displayed and the start condition is achieved. RT1 to RT3) It is possible to continue the RT game without changing the number of games after the change to the game.

  Also, during the RT (RT4) game after the end of the BB, any one of the plurality of specific symbol combinations including the re-playing role 2, the general role 2, and the general role 4 is displayed on the reel. When a predetermined start condition is achieved, the game mode can be changed to the RT (RT1-RT3) game after the specific symbol display. For example, in the RT (RT4) game after the end of the BB, the winning probability of the replaying player 1 is 1 / 7.3, and the winning probability of the replaying player 2 is 1/25 (FIG. 20). If the re-game 2 that is one of the specific symbol combinations is displayed on the reel, not only when winning but also when not winning, the game is changed to the RT (RT 1) game after the specific symbol is displayed. The winning probability of the combination 1 is set to 1 / 1.2, the winning probability of the re-playing combination 2 is set to 1/65536, and the maximum number of RT games (100) is set as an end condition.

<Description of Flag Off / RT Setting Processing Subroutine>
In the main routine of FIG. 5, when the reel fluctuation / stop subroutine (step S15) is completed, a flag-off / RT setting processing subroutine (step S16) is performed. The flag off / RT setting processing subroutine will be described in detail with reference to the flowchart of the flag off / RT setting processing subroutine shown in FIG.

  First, it is determined whether or not the gaming state is RB gaming (step S71). When it is determined that the RB game is being played (YES), the RB game process subroutine (step S72) is performed, and the process proceeds to step S77. A detailed description of the RB game processing subroutine will be described later.

  Next, when it is determined in step S71 that the gaming state is not RB gaming (NO), it is determined whether or not the gaming state is BB gaming (step S73). When it is determined that the BB game is in progress (YES), the BB game in-process subroutine (step S74) is performed, and the process proceeds to step S77. A detailed description of the BB game processing subroutine will be described later.

  Further, if it is determined in step S73 that the gaming state is not BB gaming (NO), it is determined whether or not there is a winning combination (step S75). When it is determined that there is a winning combination (YES), a winning combination processing subroutine (step S76) is performed, and the process proceeds to step S77. A detailed description of the winning combination processing subroutine will be described later.

  On the other hand, if it is determined in step S75 that there is no winning combination (NO), the process directly proceeds to step S77.

  In step S77, it is determined whether or not the NRT flag is 0 in order to determine whether or not it is in the RT state (step S77). When it is determined that the NRT flag is not 0 (YES), the number of RT games is counted (step S78). Here, the number of RT games represents the number of games after the game state is changed to a new re-game game probability variation state.

  Then, after step S78, it is determined whether or not the RT game end condition has been achieved (step S79). In the present embodiment, it is determined whether or not the number of RT games is equal to or greater than the maximum number of RT games that is an end condition (step S79). For example, when the general combination 4 which is a specific symbol is displayed on the reel, the NRT flag is set to RT3 and changed to RT game, but since the maximum number of RT games is 1000 (FIG. 19), RT The RT game ends when the number of games reaches 1000. Even if the RT game is in the RT game before the maximum number of RT games is reached, if the BB role as a special role is won, the RT game is terminated on the assumption that the RT game end condition has been achieved.

  If it is determined in step S79 that the RT game end condition has been achieved (YES), the RT game count is reset, the NRT flag is set to 0, and the RT game is ended (step S80). Then, the flag off / RT setting processing subroutine is terminated. On the other hand, when it is determined that the RT game end condition is not achieved (NO), the flag off / RT setting processing subroutine is ended.

  If it is determined in step S77 that the NRT flag is 0 (NO), that is, the game mode does not correspond to the RT state, the flag off / RT setting processing subroutine is terminated as it is. Hereinafter, a detailed description of the subroutine shown in steps S72, S74, and S76 will be given.

<Description of processing subroutine during RB game>
First, a detailed description of the RB game processing subroutine (step S72) executed when it is determined in step S71 that the RB game is being performed will be described with reference to the flowchart shown in FIG.

  First, a winning symbol determination is performed as to whether or not the reel symbol stopped by the reel fluctuation / stop subroutine (step S15) has been won (steps S81 and S82). When winning (YES), the number of winning times during RB gaming is counted (step S83), and the corresponding general combination flag during RB gaming is set to OFF (step S84). Then, the updated data is stored in the RAM 110.

  Next, it is determined whether or not the BB game is being played (step S85). When it is determined that the BB game is being played (YES), that is, the RB game is being played during the BB game, the payout number is counted to update the payout number data (step S86), and the RB game number is counted. Then, the updated data is stored in the RAM 110 (step S87). These data are used as RB game end conditions. Specifically, when the number of winnings in RB game or the number of RB games reaches a predetermined number, the RB game is ended.

  If it is determined in step S85 that the BB game is not in progress (NO), that is, if the RB game is won and the player has won but the BB game is not in the RB game, the number of RB games is counted (step S87). ), The updated data is stored in the RAM 110.

  On the other hand, if no winning is made in step S82 (NO), the number of RB games is counted (step S87), and the updated data is stored in the RAM 110.

  Next, it is determined whether or not the BB game end condition has been achieved (step S88). In the present embodiment, when the number of game medium payouts during the BB game, which is the BB game end condition, reaches a predetermined number, more specifically, “the maximum number of acquired BB games during the BB game” This is because the BB game is ended when the number of game media obtained by subtracting “the maximum number of game media to be paid out in one game” is exceeded. For example, if the maximum number of game media is 15 and the BB role (the BB game end condition is 451 from FIG. 16) is won and won, the “number of payouts during BB game” is “BB game When the number of game media exceeds 436, which is obtained by subtracting 15 from "maximum number of game media to be paid out in one game" from 451, which is the maximum number of BB games acquired in the end condition. The BB game end condition is reached, and the BB game ends.

  In step S88, when the BB game end condition is achieved (YES), the BB game state is canceled (step S89), the payout number during the BB game is reset (step S90), and the RB game state is also released (step S89). S91). Then, RT4 is set in the NRT flag (step S92). Then, the number of winnings during RB gaming and the number of RB gamings are reset (step S93), and the RB gaming processing subroutine is terminated.

  If it is determined in step S88 that the BB game end condition has not been achieved (NO), whether or not the RB game end condition has been achieved, specifically, the number of RB games won or the number of RB games is By reaching the predetermined number of times, it is determined whether or not the RB game end condition is achieved (step S94). When it is determined that the RB game end condition is achieved (YES), the RB game state is canceled (step S95). Then, the number of winnings during RB gaming and the number of RB gamings are reset (step S93), and the RB gaming processing subroutine is terminated.

  On the other hand, if it is determined in step S94 that the RB game end condition has not been achieved (NO), the RB game in-process subroutine is ended.

  In the present embodiment, the start condition for transitioning to RT (RT4) game is limited to the start condition for changing to RT game after the end of BB game included in the special game, but after the end of RB game, RT It is also possible to adopt a start condition that changes to a game.

<Description of processing subroutine during BB game>
Next, FIG. 12 shows a detailed explanation of the BB game processing subroutine (see step S74) executed when it is determined in step S73 that the BB game is being played in the flag off / RT setting processing subroutine (see FIG. 10). This will be described with reference to the flowchart shown.

  As shown in FIG. 10, the BB game processing subroutine is executed only when the BB game is not being played but the BB game is being played. That is, the gaming state is not RB gaming.

  It is determined whether or not the reel symbol stopped by the reel fluctuation / stop subroutine has won a prize (steps S101 and S102). If the RB combination is won (YES), the RB flag is turned off, that is, the RB gaming state is set (step S103). Then, the BB gaming process subroutine is terminated.

  Next, when it is determined in step S102 that the RB role has not been won (NO), it is determined whether or not any of the general role 1, the general role 2, the general role 3 or the general role 4 has been won. (Step S104). When it is determined that the winning combination is one of the general combination 1, general combination 2, general combination 3 or general combination 4 (YES), the corresponding general combination flag is set to OFF (step S105), and the number of payouts Is counted to update the payout number data (step S106), and the updated data is stored in the RAM 110. This data is used to determine whether or not the BB game end condition has been achieved (step S107).

  Specifically, when the number of game medium payouts, which is a BB game end condition, reaches a predetermined number, more specifically, from “the maximum number acquired during BB game, which is a BB game end condition”, When the number of game media obtained by subtracting the “maximum number of game media paid out in the game” is exceeded, the corresponding BB game is terminated.

  In step S107, when the BB game end condition is achieved (YES), the BB game state is canceled (step S108), and the payout number during the BB game is reset (step S109). Then, the NRT flag is set to RT4 (step S110), and the BB gaming process subroutine is terminated. As a result, the RT (RT4) game after the end of the BB can be performed from the next game.

  In step S107, if the BB game end condition is not achieved (NO), the BB game in-process subroutine is ended.

  Furthermore, when it is determined in step S104 that the general combination 1, the general combination 2, the general combination 3 and the general combination 4 are not won (NO), the re-playing combination 1 or the re-playing combination 2 is won. It is determined whether or not (step S111). When it is determined that the player has won the re-gamer 1 or the re-gamer 2 (YES), the corresponding re-gamer flag is set to OFF (step S112), and the BB gaming process subroutine is terminated. Further, when it is determined that neither the re-game player 1 nor the re-game player 2 has won (NO), the BB game in-process subroutine is terminated.

<Explanation of the processing sub-routine at the time of winning>
Next, in the flag off / RT setting processing subroutine (see FIG. 10), the detailed explanation of the winning combination processing subroutine (step S76) executed when it is determined that there is a winning combination in step S75, is a flowchart shown in FIG. It explains using.

  As shown in FIG. 10, the winning combination processing subroutine is executed only when the RB game is not being played and the BB game is not being played.

  First, a winning symbol determination is made as to whether the reel symbol stopped by the above-described reel fluctuation / stop subroutine has won a prize (step S121). Next, as a result of the winning symbol determination, it is determined whether or not the RB combination has been won (step S122).

  When it is determined that the RB combination has been won (YES), the RB flag is set to OFF (step S123), the RB gaming state is set, and this subroutine is terminated. By setting the RB game state, the RB game is started from the next game, and it is determined that the RB game is in progress.

  If it is determined in step S122 that the RB combination has not been won (NO), it is determined whether or not the BB combination has been won (step S124). When winning the BB combination (YES), the BB combination flag is set to OFF (step S125), and the winning combination processing subroutine is terminated. The next game is determined to be a BB game.

  If it is determined in step S124 that the BB combination has not been won (NO), it is determined whether or not the general combination 1, the general combination 2, the general combination 3 or the general combination 4 has been won (step S126). . If any general combination such as the general combination 1 is won (YES), the corresponding general combination flag is set to OFF (step S127), and the winning combination processing subroutine is terminated.

  If it is determined in step S126 that no general combination such as the general combination 1 has been won (NO), it is determined whether or not the replay combination 1 or the replay combination 2 has been won (step S128). ). When it is determined that any one of the re-game players has won (YES), the re-game flag is set to OFF (step S129), and the re-game state is set. Then, this subroutine ends. This makes it possible to play a game in a new re-game probability variation state from the next game.

  When it is determined in step S128 that no re-game player has been won (NO), the winning combination processing subroutine is terminated.

<Description of main routine (continued)>
As described above, the subroutine shown in steps S72, S74, and S76 ends, and the flag-off / RT setting processing subroutine shown in FIG. 10 ends. Returning to the main routine of FIG. 5, the flag-off / RT setting process subroutine of step S16 is terminated, the payout process of step S17 is terminated, and the main routine is terminated. Thereby, the control process for performing a game in which one process from when the symbol fluctuates until it stops is completed.

  As described above, according to the present embodiment, when a specific symbol combination is displayed on the reel by the reel control means, it is assumed that the predetermined game start condition is achieved, and the probability that the re-game player will win the game mode. Is changed to a replay probability variation state set to a different value, so it is not limited to a replay probability variation state game that was limited to a certain condition such as after the end of a special game, but in a normal general game In addition, when a specific symbol combination is displayed on the reel, the start condition is achieved, and the game can be changed to a re-game probability variation state game, and the number of game media that can be acquired can be increased.

  In addition, even if a specific symbol combination is displayed on the reel in the game of the re-play probability variation state after the change has already been achieved and any one of the specific symbol combinations is displayed on the reel, the same If the start condition is satisfied, it is possible to continue the game in the replay probability variation state. On the other hand, if a different start condition is achieved, the game mode is changed to a new replay probability variation state. Make it possible. As a result, the start condition can be switched between valid and invalid according to the state of the game.

  Furthermore, in the replay probability variation state in which a plurality of replaying roles are provided and the winning probability of one replaying role is increased, a specific symbol combination is displayed, and the winning probability of other replaying roles is displayed. It is possible to continue the game in a new re-game probability variation state with a higher value. As a result, it is possible to continue the interest and freshness of the player for a long time by including contents with game characteristics.
