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, when a symbol corresponding to a winning combination in a lottery is stopped and a prize is won, a game corresponding to the winning prize is played.

  Here, in this slot machine, a special combination and a re-playing combination are set as a combination, and when the special combination is won, a special game that allows a player to play a game more advantageous than the normal 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, there is a slot machine that sets a high probability of winning a regamer in a lottery when a predetermined condition is satisfied in order to increase the player's interest in games. Proposed. (For example, refer to Patent Document 1.)
JP 2001-137430 A

  In Patent Document 1, the game state is changed at a timing when a predetermined special game is finished, and the re-game probability variation state set to a value with a high probability that a re-game player is won is changed to change the progress of the game. Slot machines have been proposed. However, since the start condition for changing to the re-gaming probability variation state is limited to a certain condition such as after the end of the special game, the normal game cannot be changed to the re-gaming probability variation state. Therefore, if the game is continued for a long time, the game tends to be monotonous, and it has been difficult to continue the interest and freshness of the player for a long time.

  The present invention has been made in view of the above-described problems, and is provided when a re-playing combination is provided and one specific symbol combination is displayed on a reel from among a plurality of specific symbol combinations. As a result, it is possible to change the game state to a re-game probability variation state in which the probability that the re-game player wins is set to a value different from the value of the predetermined game state. As a result, it 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, and even during normal games, a start condition is displayed by displaying a specific symbol combination on the reel It is an object of the present invention to provide a slot machine that can be changed to a game with a re-play probability variation state and can increase the number of game media that a player can acquire.

  Further, when one specific symbol combination is displayed on the reel, the probability that the re-gamer will be won is changed to the first re-game probability fluctuation state set to a value that approximates the value of the predetermined game state. When a combination of other specific symbols is displayed on the reel, the probability that the re-gamer will win is changed to a second re-game probability fluctuation state in which the probability is higher than the value of the predetermined game state. Make it possible to do. As a result, it is possible to change between the state where the symbols of the re-gamer are easily aligned and the state where it is difficult to align. It is an object of the present invention to provide a slot machine capable of continuing the interest and freshness of a player for a long time by including a variety of games and including game-related contents.

  In order to achieve the above object, in the slot machine according to the present invention, when one specific symbol combination is displayed on the reel from among a plurality of specific symbol combinations, the re-gamer is elected. When the probability is changed to the first replay probability variation state set to a value approximating the value of the predetermined game state, and another specific symbol combination is displayed on the reel, the regame player is won There is a re-game probability variation state control means for changing to a second re-game probability variation state in which the probability is set to a value higher than the value of the predetermined game state.

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 combination lottery means for determining which combination has been won out of the combination including the re-playing combination;
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;
In a predetermined gaming state, when a specific symbol combination is displayed on the reel by the reel control means, assuming that a predetermined starting condition is achieved, the probability that the re-gamer will win is determined as the predetermined gaming condition. Re-game probability variation state control means for changing to a re-game probability variation state set to a value different from the value of the game state,
The specific symbol combination includes one specific symbol combination and another specific symbol combination;
The re-gaming probability change state control means,
When the other specific symbol combination is displayed on the reel, the probability that the re-gamer is won is changed to the second re-game probability fluctuation state in which the probability is set higher than the value of the predetermined game state. ,
When the combination of the specific symbol of the one is displayed on the reel, the first replay probability of replay combination is won is set before Symbol lower have value than the value of the second re-gaming probability change state Change to the probability variation state,
In the game in the first replay probability variation state, even if the combination of the one specific symbol or the other specific symbol combination is displayed on the reel, the first replay probability is Keep the game in a fluctuating state,
The maximum number of games of the game in the first replay probability variation state is set as the end condition of the game in the first replay probability variation state, and when the game of the maximum number of games is performed, the end condition Ending the game in the first replay probability variation state and shifting to the second replay probability variation state when the other specific symbol combination is displayed on the reel. The predetermined game state is changed.

  According to the above-described invention, when a predetermined combination of symbols is displayed on the reel by the reel control means, it is assumed that a predetermined start condition is achieved, and the game state has a predetermined probability that the re-gamer will win. Since it has a replay probability variation state control means for changing to a replay probability variation state set to a value different from the value of the state, the replay probability variation state limited to a certain condition such as after the end of a special game The game is not limited to a game, and even during a normal game, it can be changed to a game in a re-game probability variation state, assuming that the start condition is achieved by displaying a specific symbol combination on the reel. Therefore, the number of game media that can be acquired by the player is increased by changing the game state to a replay probability fluctuation state in which the probability that the re-player is won is higher than the value of the predetermined game state. be able to.

The specific symbol combination includes one specific symbol combination and another specific symbol combination, and the replay probability variation state control means displays the other specific symbol combination on the reel. The probability of winning a re-gamer is changed to the second re-game probability variation state set to a value higher than the value of the predetermined game state, and one specific symbol combination is displayed on the reel sometimes, since the probability of replay combination is won is changed to the first re-gaming probability variation state of which is set to a low have value than the value of the second re-gaming probability change state, the symbol replay combination is aligned It is possible to change between an easy state and a difficult state.

  In the first replay probability variation state, since the probability that the re-gamer is won is set to a value that approximates the value of the predetermined game state, the first replay probability variation state is given to the player. Can also give a sense of being in a predetermined gaming state. As a result, the game in the first replay probability variation state can be performed so as to perform a normal game without giving the player a sense of incongruity.

Furthermore, in the second replay probability variation state, the probability that the re-game player is won is set to a value higher than the values of the predetermined game state and the first replay probability variation state. The number of game media that can be acquired can be increased.

In addition, in the game in the first replay probability variation state, even if one specific symbol combination or another specific symbol combination is displayed on the reel, the first replay probability variation state When the game of the maximum number of games set as the end condition is performed and the game in the first replay probability variation state is ended, other specific symbol combinations are displayed on the reels. Then, it changes to the predetermined | prescribed gaming state which will transfer to a 2nd re-game probability fluctuation state.
Thereby, according to the state of the game, it is possible to switch between valid and invalid with respect to the game start condition in the re-game probability variation state after displaying the combination of specific symbols, and to further include game content This makes it possible to continue the interest and freshness of the player for a long time.
In addition, when the game in the first replay probability variation state has been played the maximum number of times, the game in the first replay probability variation state is terminated and the predetermined game state Therefore, when the game in the first replay probability variation state is finished and changed to the predetermined game state, the probability of winning the regame player is set to an approximate value. It is possible to give a player who plays a game in the re-gaming probability variation state a feeling of continuing the game in a predetermined game state. As a result, the game in the first replay probability variation state can be performed so as to perform a normal game without giving the player a sense of incongruity.

  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.

  The “combination” is transferred to a “payout part (hereinafter referred to as“ general part ”)” that pays out a predetermined number of game media when winning, and a “special game” that allows the game to proceed advantageously for the player. “Special role” that can be played, and “re-playing role” that allows the game to be re-executed without inserting game media.

  The “game state” is different from the “special game state” in which the game proceeds in an advantageous manner for the player and the probability that the re-gamer is elected when a predetermined condition is achieved. Includes "re-playing probability variation state" set to the value and "normal gaming state" in which other games are played and a game is performed using the role lottery table used in the initial state of the slot machine It is.

  “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.

  In the slot machine according to the present invention, it is preferable that the specific symbol combination includes a combination of symbols of the re-gamer.

  According to the above-described invention, when one specific symbol combination displayed on the reel in the game start condition in the first replay probability variation state is a combination of symbols of the regame combination, In the re-gaming probability variation state, the probability that the re-game player is won can be set to a value that approximates the value of a predetermined gaming state. On the other hand, when the other specific symbol combination displayed on the reel in the game start condition in the second replay probability variation state is the combination of symbols of the replaying role, the second replay probability variation state , The probability that the re-gamer is won can be set to a value higher than the value of the predetermined gaming state.

  As a slot machine according to the present invention, when a combination wins a winning combination, it includes a payout combination for paying out game media to a player, and a specific symbol combination includes a combination of symbols of a payout combination, It is preferable.

  According to the above-described invention, when one specific symbol combination displayed on the reel in the game start condition in the first replay probability variation state is a symbol combination of a payout combination, In the game probability variation state, the probability that the re-game player is won can be set to a value that approximates the value of the predetermined game state. On the other hand, when another specific symbol combination displayed on the reel in the game start condition in the second replay probability variation state is a combination of symbols for paying out, in the second replay probability variation state The probability that the re-game player is won can be set to a value higher than the value of the predetermined game state.

  As a result, one specific symbol combination is a payout combination and another specific symbol combination is a recombination symbol combination, or one specific symbol combination is a replaying combination. In addition, if the combination of other specific symbols is a combination of symbols for paying out, variations in games can be expanded, and game content can be further included in the game. Interest and freshness can last a long time.

  Furthermore, the combination of one specific symbol displayed on the reel by the reel control means and the combination of the other specific symbols are a combination of symbols of the replaying combination and the payout combination included in the combination lottery by the combination lottery unit. Therefore, since the game state is changed to the first or second replay probability variation state, it is not necessary to newly form a specific symbol combination. Therefore, without providing a means for newly forming a specific symbol combination by lottery or the like, and further, a means for performing a symbol stop process relating to the newly formed specific symbol combination, it is possible to bring gameable contents to the game. Can be included.

  As the slot machine according to the present invention, the re-gaming probability variation state control means sets the maximum number of games in the re-gaming probability variation state game as the end condition of the re-gaming probability variation state game, and plays the maximum number of games. It is preferable that the game in the re-game probability variation state is terminated and changed to a predetermined game state, assuming that the termination condition has been achieved.

  According to the above-described invention, the re-gaming probability variation state control means sets the maximum number of games of the re-gaming probability variation state game as the re-gaming probability variation state game end condition. By setting the probability of winning a re-gamer to a high value, the number of game media that can be acquired by the player is increased compared to the normal game until the maximum number of games in the re-game probability fluctuation state is reached. Can be made. Furthermore, during the game period in the re-game probability variation state, winning a special role allows the player to shift to an advantageous game, so that the player can continue to play with a sense of tension.

As a slot machine according to the present invention, the termination condition of the re-gaming probability variation state game, and, further, also seen including that was elected to the special role that can be transferred to a special game to advantageously proceed with the game for the player The re-game probability variation state control means is changed to the first re-game probability variation state when the combination of the one specific symbol is displayed on the reel in the game after the special game is ended. In the meantime, when the other specific symbol combination is displayed on the reel, it is desirable to shift to the second replay probability variation state .

  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, the specific symbol combination includes one specific symbol combination and another specific symbol combination, and the replay probability variation state control means has another specific symbol combination. Is displayed on the reel, the probability of winning a re-gamer is changed to a second re-game probability variation state in which the probability is higher than a predetermined game state value, and one particular symbol combination is changed. when displayed on the reel, the probability that the replay combination is won re gaming probability change state to change to the first re-gaming probability variation state of which is set to a low have value than the value of the second re-gaming probability change state Since it has a control means, it becomes possible to change into the state in which the symbol of a re-game player is easy to align, and the state where it is difficult to align.

  In the first replay probability variation state, since the probability that the re-gamer is won is set to a value that approximates the value of the predetermined game state, the first replay probability variation state is given to the player. Can also give a sense of being in a predetermined gaming state. As a result, the game in the first replay probability variation state can be performed so as to perform a normal game without giving the player a sense of incongruity.

  Further, in the second replay probability variation state, the probability that the re-gamer is won is set to a value higher than the value of the predetermined game state, so that the number of game media that can be acquired by the player is increased. be able to.

In addition, in the game in the first replay probability variation state, even if one specific symbol combination or another specific symbol combination is displayed on the reel, the first replay probability variation state game Because it continues, it is possible to switch between valid and invalid for the game start condition in the re-game probability variation state after displaying the combination of specific symbols according to the game state, and the game further includes game content It is possible to continue the interest and freshness of the player for a long time.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  Five winning lines are defined in front of these three display windows 22L, 22C and 22R. These five winning lines include three horizontal winning lines (center L1, upper and lower L2A, L2B) and two diagonal winning lines (diagonally downward L3A, obliquely upward L3B). A winning line (hereinafter referred to as an “effective line”) that is activated by the number of game media (in the present embodiment, medals are used) 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.

  Further, an image display device 70 composed of a liquid crystal display panel is provided above the casing of the slot machine 10. 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.

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, 40L, Each of 40C or 40R is controlled to stop.

  On the lower right side of the casing of the slot machine 10, sound is emitted from a speaker (not shown, corresponding to a speaker 64 shown in FIG. 2 described later) housed in the casing. 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.

  Display lamps 90 are provided on both the left and right sides above the casing of the slot machine 10. The display lamp 90 is composed of a plurality of LED lamps and the like, and in the case of a normal game, a constant lighting is performed.

  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. Also, in this game, after inserting the game media and operating any of the bet switches 32, 34, 36, the player tilts the start switch 50 to rotate the reels 40L, 40C and 40R. It is a game that can be repeated as a single game until the process is stopped.

  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, 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. 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.

The operation means 300 is not limited to a switch, and any means can be applied as long as it generates an operation signal based on an operation using the player's limbs.

<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 a winning combination based on the winning combination. 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 combination control of the symbols 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 FIGS. 8 and 9).

  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 performs a special game in which the game proceeds in an advantageous manner for the player. 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 state of the game can be set to a different value by the winning lottery means.

<< Description of control processing >>
<Description of Control Processing of Slot Machine 10>
Hereinafter, various controls performed by the control unit of the slot machine 10 described above will be described in detail with reference to flowcharts.

  FIG. 5 shows a main routine of control processing performed in the main control circuit 100 of the slot machine 10. 6 to 13 show subroutines which 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 process 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 of the slot machine 10 described above are initialized to predetermined values and operate in a steady state. It shall be.

<Description of main routine>
FIG. 5 shows a main routine of control processing performed in the main control circuit 100 of the slot machine 10. The control process of the main routine will be described using the flowchart of FIG. The 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 S139 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 issued by the player operating one of the 1-bet switch 32, the 2-bet switch 34, or the maximum bet switch 36. The set bet number is determined (step S11). The “set bet number” indicates the number of game media to be bet 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 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. 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. The bet number is detected from the bet operation signal, and the detected bet number is stored in the RAM 110 as a new bet number regardless of whether the game medium is inserted or the credited game medium is used, and the credited game medium is used. At the same time, a process of subtracting the number of detected bets from the number of credits of the game medium 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 by the combination lottery means 410 is performed, and a flag on for turning on the RB flag, the corresponding BB flag, the replay flag, and the corresponding general combination flag is performed 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) for 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 whether or not the NRT flag is set to RT1 (step S21). Here, the “NRT flag” is a flag for determining whether or not an RT gaming state is set. When NRT = 0, a non-RT gaming state (initial value) is specified, and when NRT = RT1 to RT2, a specific symbol is set. Represents the RT gaming state after the combination is displayed on the reel. Specifically, when NRT = RT1, the RT gaming state after displaying the general combination 2 is displayed, and when NRT = RT2, the replaying game is displayed. It represents the RT gaming state after the combination display. In addition, when NRT = RT3-5, it represents the RT gaming state after the end of the special game. Specifically, when NRT = RT3, the RT gaming state after the end of the RB game is indicated as NRT = RT4. Represents the RT gaming state after the end of the BB1 game, and when NRT = RT5, the RT gaming state after the end of the BB2 game.

  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 1 is displayed (RT1) stored in the ROM 108 (step S22). Here, FIG. 17 shows an example of the lottery table after the specific symbol 1 is displayed (RT1).

  After the specific symbol 1 is displayed (RT1), in the lottery table, the BB role 1 with the symbol number 1, the BB role 2 with the symbol number 2, the RB role with the symbol number 3, the general role with the symbol numbers 4 to 6, and the symbol number 7 The re-playing combination of No. 8 and the deviation of the symbol number 8 are set. For example, when the general combination 2 is won, the game is set so that a prize is awarded when the symbols of the bells are aligned on the first, second and third reels. Has been. For the BB combination 1 with the symbol number 1 and the BB combination 2 with the symbol number 2, the combination of the winning probability and the symbol in the combination lottery is set. Further, as the end condition, a maximum acquisition number of 297 for the BB combination 1 with the symbol number 1 and 451 for the BB combination 2 with the symbol number 2 is set.

  Further, when compared with the general lottery table when the BB is not activated (FIG. 16) used in the RB gaming state, the BB gaming state, the re-gaming state, and the normal gaming state that is not the RT gaming state, the winning probability of the re-gamer is 1/1. .23, a very high value. Therefore, during the RT (RT1) game after displaying the combination of the specific symbol 1 (the combination of the general character 2), the possibility of winning the re-game character is extremely high compared to the normal game. It can be felt that the player is playing a game different from the normal game. Further, the number of game media that can be acquired by the player can be increased.

  Further, when the general combination 2 as the specific symbol 1 is displayed on the reel by the reel control means, it is changed to RT (RT1) game, and the RT (RT1) game end condition is the maximum RT game count (70 times). ) Is set. Therefore, if the RT (RT1) game after the display of the combination of the specific symbol 1 (the combination of the symbols of the general role 2) is performed 70 times, the RT (RT1) game after the display of the specific symbol 1 is finished, and the state of the game is Return to the normal gaming state.

  In addition, during the 70 RT (RT1) games after the display of the combination of the specific symbol 1 (combination of the symbols of the general combination 2), the combination of the general combination 2 or other specific symbols (the combination of the symbols of the re-playing combination) ) Is displayed, the game is continued without changing the RT (RT1) game state without newly resetting the RT game count in step S62 or step S63 of the reel change / stop subroutine described later. . On the other hand, when the special role is won, the RT1 game is ended.

  Then, after the specific symbol 1 is displayed (RT1), the lottery table is read, and then a lottery for acquiring a random number and performing 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). If it is determined that the NRT flag is set to RT2 (YES), the lottery table is read after the specific symbol 2 display (RT2) stored in the ROM 108 (step S25). Here, FIG. 18 shows an example of the lottery table after the specific symbol 2 is displayed (RT2).

  After the specific symbol 2 is displayed (RT2), in the lottery table, the BB role 1 with the symbol number 1, the BB role 2 with the symbol number 2, the RB role with the symbol number 3, the general role with the symbol numbers 4 to 6, and the symbol number 7 re-games and symbol number 8 are set off. Further, for the BB combination 1 with the symbol number 1 and the BB combination 2 with the symbol number 2, the maximum acquisition number of 297 and 451 is set as the ending condition, respectively. Further, compared with the general lottery table when the BB is not operated (FIG. 16), the winning probability of the re-gamer is set to 1 / 7.29 which is substantially the same but is slightly higher. Therefore, compared with the normal game, during the RT (RT2) game after the display of the specific symbol 2, the possibility of winning the re-game is almost the same, so even during the normal game that is a non-RT game (RT2) It is possible to cause a player to feel as if the game is being played.

  Furthermore, when the re-game combination which is a specific symbol is displayed on the reel by the reel control means, it is changed to RT (RT 2) game and, as shown in FIG. (1000 times) is set. Therefore, if the RT (RT2) game after displaying the combination of the specific symbol 2 (recombination game symbol combination) is performed 1000 times, the RT (RT2) game after the specific symbol 2 display is completed, and the game state is Return to normal gaming state.

  If a re-game combination or another specific symbol combination (general combination 2) is displayed during 1000 RT games after the display of the combination of specific symbols 2 (re-game combination symbol combination), it will be described later. In step S62 or step S63 of the reel change / stop subroutine, the game is continued without changing the RT (RT2) game state without newly resetting the RT game count. On the other hand, when the special combination is won, on the other hand, when the special combination is won, the RT2 game is terminated.

  If it is determined in step S24 that the NRT flag is not RT2 (NO), it is 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 completion of the RB game (RT3) stored in the ROM 108 (step S27). Here, FIG. 19 shows an example of the lottery table after the end of the RB game.

After the RB game is over (RT3), in the lottery table, the BB combination 1 with the symbol number 1, the BB combination 2 with the symbol number 2, the RB combination with the symbol number 3, the general combination with the symbol numbers 4 to 6, and the symbol number 7 A re-playing combination and a deviation of symbol number 8 are set. Further, for the BB combination 1 with the symbol number 1 and the BB combination 2 with the symbol number 2, the maximum acquisition number of 297 and 451 is set as the ending condition, respectively. Further, compared with the general lottery table when BB is not operating (FIG. 16), the winning probability of the re-gamer is set to a high value of 1 / 5.46. Therefore, as compared with the normal game, the possibility of winning the re-game is increased during the RT (RT3) game after the end of the RB game.
Further, when the RB game ends, the RT (RT3) game start condition is achieved and the RT (RT3) game is changed to the RT (RT3) game, and as shown in FIG. 3 times) is set. Therefore, if the RT (RT3) game after the end of the RB game is performed three times, the RT (RT3) game after the end of the RB game is ended, and the game state returns to the normal game state. Further, when the general combination 2 or the re-playing combination is displayed during the three RT (RT3) games after the end of the RB game, the state of the game is changed to the state of the RT1 game or the RT2 game.

  If it is determined in step S26 that the NRT flag is not RT3 (NO), it is 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 the end of the BB1 game (RT4) stored in the ROM 108 (step S29). Here, FIG. 20 shows an example of the lottery table after the end of the BB1 game (RT4).

  After the BB1 game is over (RT4), in the lottery table, the BB role 1 with the symbol number 1, the BB role 2 with the symbol number 2, the RB role with the symbol number 3, the general role with the symbol numbers 4 to 6, and the symbol number 7 A re-playing combination and a deviation of symbol number 8 are set. Further, for the BB combination 1 with the symbol number 1 and the BB combination 2 with the symbol number 2, the maximum acquisition number of 297 and 451 is set as the ending condition, respectively. Further, when compared with the general lottery table when the BB is not operated (FIG. 16), the winning probability of the re-gamer is set to be substantially the same value as 1 / 7.28. Therefore, compared with the normal game, the possibility of winning the re-gamer is almost the same during the RT (RT4) game after the end of the BB1 game, so the RT ( RT4) It is possible to cause the player to feel as if the game is being played.

  Further, when the BB1 game ends, the RT (RT4) game start condition is reached and the RT (RT4) game is changed to the RT (RT4) game, and as shown in FIG. 3 times) is set. Therefore, when the RT (RT4) game after the end of the BB1 game is performed three times, the RT (RT4) game after the end of the BB1 game is ended, and the game state returns to the normal game state. Further, when the general combination 2 or the re-playing combination is displayed during the three RT (RT4) games after the end of the BB1 game, the state of the game is changed to the state of the RT1 game or the RT2 game.

  If it is determined in step S28 that the NRT flag is not RT4 (NO), it is determined whether or not the NRT flag is set to RT5 (step S30). When it is determined that the NRT flag is set to RT5 (YES), the lottery table is read after the end of the BB2 game (RT5) stored in the ROM 108 (step S31). Here, FIG. 21 shows an example of a lottery table after the end of BB2 game (RT5).

  After the BB1 game is over (RT5), in the lottery table, the BB role 1 with the symbol number 1, the BB role 2 with the symbol number 2, the RB role with the symbol number 3, the general role with the symbol numbers 4 to 6, and the symbol number 7 A re-playing combination and a deviation of symbol number 8 are set. Further, for the BB combination 1 with the symbol number 1 and the BB combination 2 with the symbol number 2, the maximum acquisition number of 297 and 451 is set as the ending condition, respectively. In addition, compared with the general lottery table when the BB is not operated (FIG. 16), the winning probability of the re-gamer is set to a high value of 1 / 4.00. Therefore, the possibility of winning the re-gamer is extremely high compared to that during the normal game, and it can be realized that the player is playing a game different from the normal game. Further, the number of game media that can be acquired by the player can be increased.

  Further, when the BB2 game ends, the RT (RT5) game start condition is achieved and the RT (RT5) game is changed to the RT (RT5) game. 3 times) is set. Therefore, if the RT (RT5) game after the end of the BB2 game is performed three times, the RT (RT5) game after the end of the BB2 game is ended, and the game state returns to the normal game state. Further, when the general combination 2 or the re-playing combination is displayed during the three RT (RT5) games after the end of the BB2 game, the state of the game is changed to the state of the RT1 game or the RT2 game.

  If it is determined in step S30 that the NRT flag is not RT5 (NO), it is determined whether or not the state of the game is an RB game (step S32). When it is determined that the game state is RB game (YES), the RB lottery table stored in the ROM 108 is read (step S33). Here, an example of the RB lottery table is shown in FIG.

  In the RB lottery table, a general combination with symbol numbers 1 to 3 and a deviation of symbol number 4 are set. For example, in the case of the general combination 2, the symbols of the bells on the first, second and third reels are set. It is set to win a prize when it is complete. Here, since the probability that the general combination 2 wins is set to a very high value of 1 / 1.03, the possibility of winning the general combination 2 is very high during the RB game. . On the contrary, the probability of loss is set as low as about 1 / 212.5.

  If it is determined in step S32 that the game state is not RB game (NO), it is determined whether the game state is BB1 game or BB2 game (step S34). When it is determined that the game state is BB1 game or BB2 game (YES), the lottery table for BB operation stored in the ROM 108 is read (step S35). Here, FIG. 15 shows an example of the BB operation lottery table.

  In the BB operation lottery table, an RB combination of symbol number 1, a general combination of symbol numbers 2 to 4, and a deviation of symbol number 5 are set. Here, in comparison with the BB non-operating general lottery table (FIG. 16), the BB operating lottery table is set to have no BB combination and re-game combination.

  The RB combination with symbol number 1 is set to win if the winning probability in the combination lottery is 1/4, and the first and second reels are replayed and the third reel has a bell symbol. Yes. In the BB non-operating general lottery table (FIG. 16), the winning probability of the RB role in the role lottery is 1/300, and the probability of winning the RB role is much higher in the BB1 or BB2 game than in the normal time. Is set.

  Further, the general combination 1 with the symbol number 2 is set to win when the winning probability in the combination lottery is 1 / 81.9 and all three reels have the watermelon symbols. The general combination 2 with the symbol number 3 is set to win when the winning probability in the combination lottery is 1 / 20.0 and all three reels have the same bell symbol. If the winning combination probability in the winning combination lottery is 1 / 81.9 and the symbol of the first reel is cherry, any of the symbols of the remaining reels is Is also set to win.

  In this embodiment, in step S35, the BB operation lottery table of FIG. 15 is read even during the BB1 game or the BB2 game, but the BB1 game is different from the BB2 game. It is also possible to read out the lottery table.

  If it is determined in step S34 that none of the BB games is in play (NO), the general lottery table when the BB is not operating stored in the ROM 108 is read (step S36). Here, an example of the general lottery table when the BB is not operated is shown in FIG.

  The BB non-operating general lottery table is a lottery table used in the special game (RB game, BB1 game, BB2 game) and the normal game state which is not the RT game state. The BB role 1 of the symbol number 1 and the symbol number 2 BB role 2, symbol number 3 RB role, symbol numbers 4-6 general role, symbol number 7 re-playing role and symbol number 8 off are set, and the winning probability of re-playing role is 1 / 7.30. Further, for the BB combination 1 with the symbol number 1 and the BB combination 2 with the symbol number 2, the maximum acquisition number of 297 and 451 is set as the ending condition, respectively.

  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 S37). When it is determined that the RB combination is won (YES), the RB flag is set to ON (step S38), and it is determined whether or not the NRT flag is 0 (step S39). If it is determined that the NRT flag is not 0 (YES), that is, it is in the RT gaming state, since the RB role as a special role is won, the NRT flag is set to 0 to end the RT game (step S40). ). Then, the process proceeds to step S41. Thereby, from the next game, the normal game using the general lottery table when the BB is not operated can be performed. If it is determined in step S39 that the NRT flag is 0 (NO), that is, it is in a non-RT gaming state, no RT game is performed, so there is no need to change to a non-RT game. Go to step 110 and store in RAM 110.

  If it is determined in step S37 that the RB combination has not been won (NO), it is next determined whether or not BB combination 1 or BB combination 2 has been won (step S42). When it is determined that the BB combination 1 or the BB combination 2 is won by the combination lottery (YES), the corresponding BB flag is set to ON (step S43). Then, it is determined whether or not the NRT flag is 0 (step S39). When the NRT flag is not 0 (YES), that is, when it is determined that it is in the RT gaming state, the NRT flag is set to 0 in order to end the RT game because the BB role 1 or BB role 2 which is a special role is won. Set (step S40). Then, the process proceeds to step S41. Thereby, from the next game, the normal game using the general lottery table when the BB is not operated can be performed. If it is determined in step S39 that the NRT flag is 0 (NO), that is, it is in a non-RT gaming state, no RT game is performed, so there is no need to change to a non-RT game. Go to step 110 and store in RAM 110.

  As a result, when a special role such as an RB role is won during RT game, not only the game in the replay probability variation state is terminated, but the special game state in which the player is interested is continuously set. It becomes possible.

  In step S42, when it is determined that the BB combination 1 and the BB combination 2 are not won (NO), it is determined whether any of the general combination 1, the general combination 2, or the general combination 3 is selected. (Step S44). If it is determined that one of the general combinations 1 is won (YES), the corresponding general combination flag is set to ON (step S45), the process proceeds to step S41, and is stored in the RAM 110.

  Next, when it is determined in step S44 that no general combination has been won (NO), it is determined whether or not a re-game combination has been won (step S46). When it is determined that the re-game player is won (YES), the re-game flag is turned on (step S47), the process proceeds to step S41, and is stored in the RAM 110.

  Furthermore, if it is determined in step S46 that the re-playing role has not been won (NO), has any of the general role 1, general role 2, or general role 3 in the RB game been won? It is determined whether or not (step S48). When it is determined that one of the general combinations in the RB game is won (YES), the corresponding general combination flag in the RB game is turned on (step S49), the process proceeds to step S41, and is stored in the RAM 110. If it is determined in step S48 that none of the general roles 1, general role 2, or general role 3 in the corresponding RB game is won (NO), the flag on process is not performed. Proceed to step S41.

  As described above, after performing a series of processes related to flag-on, in step S41, 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 S41 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 a signal 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 80L 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 80C for rotating the second reel 40C is performed, so that the third reel is stopped. When the stop switch 52R is pushed, a third reel stop signal is transmitted, and stop control of the motor 80R 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, if any reel stop signal is received, it is determined whether or not there is a winning combination, and then it is determined that there is a winning combination, and the symbol corresponding to the winning combination within the reel stop possible range is determined. If there is, a symbol stop process for stopping the symbol at the active line is performed (step S58).

  After the symbol stop process in step S58, it is determined whether or not all reels have stopped (step S59). When 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 reels are stopped (YES), the process proceeds to step S60.

  In step S60, it is determined whether or not the RB flag is set to ON (step S60). If it is determined in step S60 that the RB flag is set to ON (YES), since the gaming state is playing inside the RB after winning the RB combination, it is the initial value set in step S40. This subroutine is terminated without changing the setting of the NRT flag while keeping 0.

  If it is determined in step S60 that the RB flag is not set to ON (NO), that is, it is set to off, it is determined whether or not the BB flag is set to on (step S61). If it is determined in step S61 that the BB flag is set to ON (YES), the game state is in-game inside the BB after winning any BB combination, so the initial value set in step S40 This subroutine is terminated without changing the setting of the NRT flag while maintaining 0.

  If it is determined in step S61 that the BB flag is not set to ON (NO), that is, it is set to OFF, it is determined whether or not the NRT flag is set to RT1 (step S62). If it is determined in step S62 that the NRT flag is set to RT1 (YES), this subroutine is terminated without changing the gaming state because it is in the RT1 gaming state.

  If it is determined in step S62 that the NRT flag is not set to RT1 (NO), it is determined whether or not the NRT flag is set to RT2 (step S63). If it is determined in step S63 that the NRT flag is set to RT2 (YES), this subroutine is terminated without changing the gaming state because it is in the RT2 gaming state.

  If it is determined in step S63 that the NRT flag is not set to RT2 (NO), it is determined whether or not the combination of symbols of the general combination 2 as the specific symbol 1 is displayed on the reel (see FIG. Step S64). In step S64, when it is determined that the combination of symbols of the general combination 2 as the specific symbol 1 is displayed on the reel (YES), the NRT flag is set to RT1, and the RT game count is reset. After the specific symbol 1 is displayed in FIG. 17 (RT1), the maximum RT game count of 70 in the lottery table is set as the RT1 game end condition (step S65). Then, this subroutine ends. As a result, the RT1 game can be performed from the next game, and the number of times the RT1 game has been performed can be counted.

  In step S64, when it is determined that the combination of symbols of the general combination 2 that is the specific symbol 1 is not displayed on the reel (NO), the combination of symbols of the re-playing combination that is the specific symbol 2 is complete. It is determined whether or not the image is displayed on the reel (step S66). In step S66, when it is determined that all the combinations of symbols of the re-gamer that is the specific symbol 2 are displayed on the reel (YES), the NRT flag is set to RT2, and the RT game number is reset. After the specific symbol 2 display in FIG. 18 (RT2), 1000 times that is the maximum number of RT games in the lottery table is set as an RT2 game end condition (step S67). Then, this subroutine ends. As a result, the RT2 game can be performed from the next game, and the number of times the RT2 game has been performed can be counted.

  Further, when it is determined in step S66 that the combinations of re-game players of the specific symbol 2 are not displayed on the reels (NO), this subroutine is terminated as it is.

As a result, in the game state in which the RB flag or one of the BB flaves is set to ON in step S60 and step S61, that is, during the game in the internal middle game state after winning the special role, the general combination that is the specific symbol 1 Even if the symbols of the re-gamer 2 or the specific symbol 2 are all displayed on the reel, the game is not changed to the RT game state, and the game in the internal middle game state after the special role winning is continued. Can do.
In the game state in which the NRT flag is set to RT1 or RT2 in step S62 and step S63, that is, in the state of RT1 game or RT2 game, the general game 2 that is the specific symbol 1 or the re-game character that is the specific symbol 2 Even if all the symbols are displayed on the reel, the RT game state is not changed, and the RT1 game or the RT2 game is not changed without changing the remaining number of games until the maximum number of RT games is reached. Can continue.

Further, when the determinations in step S62 and step S63 are NO, in the gaming state in which the NRT flag is set to any of RT3 to RT5, that is, in the state of the RT game (RT3 to RT5) after the end of the special game, the specific symbol If the symbols of the general combination 2 that is 1 or the replaying combination that is the specific symbol 2 are displayed on the reel, the NRT flag is set to NRT1 or NRT2 assuming that the start condition is achieved (steps S64 to S64). In step S67), the state can be changed from the next game to the RT1 game or the RT2 game.
As described above, according to the state of the game, it is possible to switch between valid and invalid with respect to the RT game start condition after displaying the combination of specific symbols, and it is possible to further include game content. , The player's interest in games and freshness can be continued for a long time.

<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 executed, 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 the gaming state is BB1 gaming or BB2 gaming (step S73). If it is determined that any of the BB games is being played (YES), the BB gaming process subroutine (step S74) is executed, 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 in any BB game (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 executed, 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 gaming 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” is the number of games after the game state is changed to a new RT game 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, if the symbol of the general combination 2 which is the specific symbol 1 is displayed on the reels, the NRT flag is set to RT1, the maximum number of RT games is set to 70 times (FIG. 17), and the RT1 gaming state Changed to Therefore, during the RT1 game, the RT1 game is terminated when the number of RT games reaches 70. In addition, even if the RT game number is in the RT1 game before reaching the maximum RT game number, if the special role RB role, BB role 1 or BB role 2 is won, the RT1 game end condition is achieved. As a result, the RT1 game is ended (step S40).

  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, the RT game is ended (step S80), flag off / RT setting The processing subroutine ends. On the other hand, if it is determined in step S79 that the RT game end condition is not achieved (NO), the next game also continues the RT game, so the NRT flag setting is not changed and the flag off / RT setting processing subroutine is executed. finish.

As a result, in the RT1 game in which the probability that the re-gamer is won is set to a high value, the number of game media that can be acquired by the player is increased as compared with the normal game until the maximum number of games is reached. it can. Further, during the RT1 game, by winning a special role, the game is shifted to an advantageous game, so that a game in which the player's tension is maintained can be performed.
Furthermore, in the RT2 game in which the probability that the re-gamer is won is set to an approximate value, if the RT game number of times reaches the maximum game number and the RT game end condition is reached, the RT2 game It is possible to give the player who performs the game a feeling of continuing the normal game. As a result, the RT2 game can be performed so as to perform the normal game without causing the player to feel uncomfortable.
.

  If it is determined in step S77 that the NRT flag is 0 (NO), that is, the gaming state does not correspond to the RT gaming 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>
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 a BB1 game or a BB2 game is being played (step S85). If it is determined in step S85 that any BB game is being played (YES), that is, if an RB game is being played in the BB game, the payout number data is counted and the payout number data is updated (step S86). Then, the number of RB games is counted (step S87), and the updated data is stored in the RAM 110. 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 none of the BB games is in progress (NO), that is, it is determined that a prize has been won in an RB game that is not in the BB game, the number of RB games is counted (step S87), and the updated data Is stored in the RAM 110.

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

  Next, after counting the number of RB games in step S87, it is determined whether the BB1 game or the BB2 game is in progress (step S88). If it is determined in step S88 that any BB game is in progress (YES), it is determined whether or not the BB game end condition has been achieved (step S89). In the present embodiment, when the number of game medium payouts during BB game, which is a BB game end condition, reaches the maximum acquired number, more specifically, “maximum acquired number during BB game, which is a BB game end condition” When the number of game media is reduced by subtracting “the maximum number of game media to be paid out in one game” from “,” the BB game is terminated. For example, if the maximum number of game media is 15 and BB role 2 (the BB2 game end condition is 451 from FIG. 16) is won and won, the “number of payout during BB game” is “BB game”. When the number of game media exceeds 436, which is obtained by subtracting 15 from "the maximum number of game media to be paid out in one game" from 451 which is the "maximum number of BB games acquired during the end of the game" The BB2 game end condition is reached, and the BB2 game ends.

  If it is determined in step S89 that the BB game end condition is achieved (YES), it is determined whether or not the gaming state is BB1 game (step S90). If it is determined in step S90 that the BB1 game is being played (YES), the NRT flag is set to RT4, the RT game count is reset, and after the end of BB1 (RT4) in FIG. 20, the maximum RT game count is set. A certain 3 times is set as an RT4 game end condition (step S91). On the other hand, if it is determined in step S90 that the BB1 game is not being played (NO), that is, that the BB2 game is being played, the NRT flag is set to RT5, the RT game count is reset, and after BB2 in FIG. ) Three times that is the maximum number of RT games in the lottery table are set as the RT5 game end condition (step S92). As a result, from the next game, the RT4 game can be played after the end of the BB1 game, the RT5 game can be played after the end of the BB2 game, and the number of times the RT game has been played can be counted.

  Then, the BB1 gaming state or the BB2 gaming state is canceled (step S93), the payout number during the BB gaming is reset (step S94), and the RB gaming state is also canceled (step S95). Then, the number of winnings during RB gaming and the number of RB gamings are reset (step S96), and the RB gaming processing subroutine ends.

  If it is determined in step S89 that none of the BB game end conditions have been achieved (NO), whether or not the RB game end condition has been achieved, specifically, the number of winnings during RB gaming or RB gaming When the number of times reaches a predetermined number, it is determined whether or not the RB game end condition is achieved (step S97). 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 S96), and the RB gaming processing subroutine ends. On the other hand, if it is determined in step S97 that the RB game end condition has not been achieved (NO), the RB game in-process subroutine is ended.

  If it is determined in step S88 that none of the BB games is in progress (NO), that is, if the RB game is not in progress, it is determined whether or not the RB game end condition has been achieved (step S98). . If it is determined in step S98 that the RB game end condition has been achieved (YES), the NRT flag is set to RT3, the RT game count is reset, and after the RB end (RT3) in FIG. Three times, which is the maximum number of RT games, is set as an RT3 game end condition (step S99). As a result, the RT3 game can be played from the next game, and the number of times the RT game is played can be counted. Then, the RB gaming state is canceled (step S100), the number of wins during RB gaming and the number of RB games are reset (step S101), and the RB gaming processing subroutine is terminated.

  On the other hand, when it is determined in step S98 that the RB game end condition has not been achieved (NO), the RB game in-process subroutine is ended.

<Description of processing subroutine during BB game>
Next, in the flag off / RT setting processing subroutine (see FIG. 10), a detailed explanation of the BB gaming processing subroutine (step S74) that is executed when it is determined in step S73 that the BB1 gaming or the BB2 gaming is in progress. This will be described with reference to the flowchart shown in FIG. 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 winning symbol (steps S111 and S112). If it is determined that the player has won the RB combination (YES), the RB flag is turned off, that is, the RB gaming state is set (step S113). Then, the BB gaming process subroutine is terminated.

  Next, when it is determined in step S112 that the RB combination has not been won (NO), it is determined whether or not any of the general combination 1, general combination 2 or general combination 3 has been won. (Step S114). If it is determined that any of the general combinations has been won (YES), the corresponding general combination flag is set to OFF (step S115), the number of payouts is counted and the payout number data is updated (step S116). 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 S117). 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.

  If it is determined in step S117 that the BB1 game or BB2 game end condition has been achieved (YES), it is determined whether or not the gaming state is BB1 game (step S118). If it is determined in step S118 that the BB1 game is being played (YES), the NRT flag is set to RT4, the RT game count is reset, and after the end of BB1 (RT4) in FIG. 20, the maximum RT game count is set. A certain 3 times is set as an RT4 game end condition (step S119). On the other hand, when it is determined in step S118 that the BB1 game is not being played (NO), that is, that the BB2 game is being played, the NRT flag is set to RT5, the RT game count is reset, and after BB2 in FIG. ) Three times which is the maximum number of RT games in the lottery table is set as the RT5 game end condition (step S120). As a result, from the next game, the RT4 game can be played after the end of the BB1 game, the RT5 game can be played after the end of the BB2 game, and the number of times the RT game has been played can be counted.

  Then, the BB1 gaming state or the BB2 gaming state is canceled (step S121), the payout number during the BB game is reset (step S122), and the BB gaming processing subroutine is ended.

  If it is determined in step S117 that the BB game end condition has not been achieved (NO), the BB game in-process subroutine is ended. Furthermore, when it is determined in step S114 that no general combination has been won (NO), the BB gaming 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 reel fluctuation / stop subroutine described above has won a prize (step S131). Next, as a result of the winning symbol determination, it is determined whether or not the RB combination has been won (step S132).

  If it is determined in step S132 that the RB combination has been won (YES), the RB flag is set to OFF (step S133), the RB gaming state is set, and the combination selection processing 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 S132 that the RB combination has not been won (NO), it is determined whether or not the BB combination 1 or BB combination 2 has been won (step S134). If it is determined that any BB combination has been won (YES), the corresponding BB combination flag is set to OFF (step S135), the BB gaming state is set, and the combination selection processing subroutine is terminated. By setting the BB game state, the BB game is started from the next game, and is determined as the BB game.

  If it is determined in step S134 that no BB combination has been won (NO), it is determined whether or not the general combination 1, the general combination 2 or the general combination 3 has been won (step S136). When it is determined that any of the general combinations has been won (YES), the corresponding general combination flag is set to OFF (step S137), and the combination winning time processing subroutine is terminated.

  If it is determined in step S136 that no general combination has been won (NO), it is determined whether or not a re-game combination has been won (step S138). When it is determined that the re-playing combination is won (YES), the re-playing flag is set to OFF (step S139), the re-playing state is set, and the winning combination processing subroutine is terminated.

  If it is determined in step S138 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, the re-game player wins the game state on the assumption that the predetermined start condition is achieved. Since it has a re-gaming probability fluctuation state control means for changing to a re-gaming probability fluctuation state set to a value different from the value of the predetermined gaming state, the re-play limited to a certain condition such as after the end of the special game. It is not limited to a game with a game probability variation state, and even during a normal game, it can be changed to a game with a re-game probability variation state, assuming that the start condition is achieved by displaying a specific symbol combination on the reel. . Therefore, the number of game media that can be acquired by the player is increased by changing the game state to a replay probability fluctuation state in which the probability that the re-player is won is higher than the value of the predetermined game state. be able to.

  In addition, the specific symbol combination includes one specific symbol combination and another specific symbol combination, and the replay probability variation state control means displays the one specific symbol combination on the reel. The probability that the re-gamer will win is changed to the first re-game probability variation state set to a value that approximates the value of the predetermined game state, and other specific symbol combinations are displayed on the reels. Sometimes, since the probability of winning a re-gamer is changed to the second re-game probability fluctuation state set to a value higher than the value of the predetermined game state, it is difficult to match the state where the re-gamer's symbols are easily aligned. It becomes possible to change to the state.

  In the first replay probability variation state, since the probability that the re-gamer is won is set to a value that approximates the value of the predetermined game state, the first replay probability variation state is given to the player. Can also give a sense of being in a predetermined gaming state. As a result, the game in the first replay probability variation state can be performed so as to perform a normal game without giving the player a sense of incongruity.

  Further, in the second replay probability variation state, the probability that the re-gamer is won is set to a value higher than the value of the predetermined game state, so that the number of game media that can be acquired by the player is increased. be able to.

  In addition, in the game in the first replay probability variation state or the second replay probability variation state game, even if any specific symbol combination is displayed on the reel, the replay probability variation Since the game of the state is continued, it is possible to switch between valid and invalid with respect to the game start condition in the re-game probability variation state after displaying the combination of specific symbols according to the state of the game. Further, it can be included in the game, and the interest and freshness of the player's game can be continued for a long time.
