Description

  The present invention relates to a slot machine, and more particularly, to a slot machine having a notification game state for notifying information according to the type of a small combination display result determined to permit derivation.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and each reel has a start lever by a player. Rotation is started by operating, and when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a range of a predetermined maximum delay time from the operation timing. . Then, a prize is generated according to the display mode derived when the rotation of all the reels is stopped.

  The type of winning combination in the slot machine is a special role with a transition to a special gaming state called a bonus, a small role with payout of medals, or a replay that allows the next game to be played without setting the number of bets again. There is a game player (replay). Neither of these combinations will win a prize unless an internal lottery performed before the display result is derived to the variable display device (usually when the start lever is operated) is won. In addition, some of the winning combinations in the slot machine will always win if the internal lottery is won, but the winning combination will be made on condition that the stop button has been operated according to a predetermined operating procedure. There are also things.

  In addition, the game in the slot machine prevents the game from becoming monotonous by controlling the game state between a game state advantageous to the player, such as the special game state described above, and a normal game state. However, in order to further improve the interest of the game, there is a game with a specific game state that is advantageous to the player, which is different from the special game state. Well-known examples of such a specific gaming state include RT (Replay Time), AT (Assist Time), and the like that increase the winning probability of replay compared to the normal gaming state.

  Here, in the slot machine equipped with AT, when the operating procedure of the stop button for winning a prize is different for each kind of small part, When winning in the internal lottery, there is one that notifies the player of the type of the winning small role itself (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2002-11152 (FIG. 1, paragraph 0048)

  However, in the slot machine of Patent Document 1, when a small role is won at AT, only the type of the selected small role is notified as it is, and the player is notified when such notification is performed. However, only the option of operating the stop button in the operation procedure uniquely identified from the notified information (that is, the operation procedure for winning the winning combination notified of the winning combination) can be taken. For this reason, there is a possibility that the game in AT becomes monotonous.

  The present invention provides a player with an opportunity to think about the selection of a game operation even when notifying information according to the type of the small role display result that has been determined to permit derivation. It is an object to provide a slot machine that can be generated.

To achieve the above object, a slot machine according to the present invention includes:
A game can be started by setting a predetermined number of bets for one game using a game value (medal), and a variable display device (variable display device 2) that displays a plurality of types of identification information in a variable manner. ) Is a slot machine (slot machine 1) in which one game is completed when a display result is derived and a winning can be generated according to the display result derived to the variable display device,
A winning display including a plurality of kinds of small role display results (watermelon, bell, cherry, special A to special C) accompanied by the addition of the game value before the display result of the variable display device is derived for each game. A pre-determining means (step S3) for determining whether to permit the derivation of the result;
Stop operation means (stop buttons 12L, 12C, 12R) operated by the player to stop the variation display of the identification information;
Derivation control means (step S4) for causing the variable display device to derive a display result in accordance with a determination result of the prior determination means and an operation procedure of the stop operation means;
Specific game state control means (step S309) for controlling the game state to a specific game state (RT) that is more advantageous to the player than the normal game state when a predetermined specific transition condition is established;
In the specific gaming state, when it is determined by the pre-determining means that the derivation of any one of the plurality of types of small combination display results is allowed, the small combination display result determined to allow the derivation Small role notifying means (steps S423 and S425) for notifying information according to the type (red or yellow of the background color);
A game value that gives a number of game values according to the type of the derived small role display result when any of the plurality of types of small role display results is derived as the display result of the variable display device Providing means (step S302),
The derivation control means includes
When it is determined by the pre-determining means that derivation of the first type of small combination display result (special A) among the plurality of types of small combination display results is permitted, the first procedure (the left reel 3L) The first type of small combination display result is derived on the condition that the stop operation means is operated at a timing at which “red 7” can be derived)
When it is determined by the pre-determining means that derivation of the second type of small combination display result (cherry) among the plurality of types of small combination display results is permitted, at least a part of the first procedure is the first procedure. Under the condition that the stop operation means is operated in a different second procedure (timing at which “cherry” can be derived to the left reel 3L), the second type of small combination display result is derived,
When it is determined by the pre-determining means that the derivation of the third type of small combination display result (special B) among the plural types of small combination display results is permitted, the operation in the first procedure is included. The third type of small combination display result is derived on the condition that the stop operation means is operated in a third procedure (timing at which “yellow 7” can be derived to the left reel 3L),
When it is determined by the pre-decision means that derivation of the fourth type of small combination display result (bell) among the plurality of types of small combination display results is permitted, at least a part of the third procedure The fourth type of small type is provided on the condition that the stop operation means is operated in a fourth procedure that is different and does not include an operation in the second procedure (a timing at which “bell” can be derived to the left reel 3L). The role display result is derived,
The small role notification means includes:
When it is determined that the derivation of the first type of small combination display result or the second type of small combination display result is permitted, the first type of small combination display result or the second type of small combination display Informing the first information (background color is red) indicating that it is determined to allow any derivation of the display result,
When it is determined that derivation of the third type of small combination display result or the fourth type of small combination display result is permitted, the third type of small combination display result or the fourth type of small combination display The second information (background color is yellow) indicating that it is determined to permit any derivation of the display result is notified.

  In the slot machine, the information according to the type of the small combination display result determined to be permitted to be derived by the predetermining means is notified when controlled to the specific gaming state. When it is determined that the derivation of the result is permitted and when it is determined that the derivation of the second type of small role display result is permitted, the first information derives the third type of small role display result. The second information is notified when it is determined that it is permitted and when it is determined that the derivation of the fourth type small part display result is permitted. Here, the second procedure for deriving the second type of small combination display result is at least partially different from the first procedure for deriving the first type of small combination display result. The fourth procedure for deriving the fourth type of small combination display result is at least partially different from the third procedure for deriving the third type of small combination display result.

  For this reason, even when the first information or the second information is notified by the small role notification means in the specific gaming state, the player does not have to operate the stop operation means while following the information. It is necessary to select how to operate the stop operation means. As a result, the game in the game in which the information according to the type of the small role display result determined to allow derivation by the pre-determining means in the specific gaming state is not too monotonous, and the entertainment of the game Can be improved.

  Further, if the stop operation means is operated in the first procedure, the third kind of small combination display result cannot be derived, and if the stop operation means is operated in the second procedure, the fourth type The small role display result cannot be derived. Similarly, if the stop operation means is operated in the third procedure, the first type of small combination display result cannot be derived. If the stop operation means is operated in the fourth procedure, the second type The small role display result cannot be derived. For example, even if the player wants to derive either the first type of small role display result or the third type of small role display result, it is a common procedure of stop operation means that can derive both There is no. For this reason, when the information is not notified from the small role notification means, the player must select the operation procedure of the stop operation means, and the game does not become monotonous.

In the above slot machine,
The small combination notifying means determines the small combination display result determined to allow derivation by the prior determination means until a predetermined period (5 games (in the case of no double up)) has elapsed in the specific gaming state. It is good also as what alert | reports the information according to the kind of. The predetermined period can be, for example, the number of times notification is performed by the small role notification means.

In the above slot machine,
The game value giving means is:
When the first type of small combination display result is derived, a larger number of game values are given than when the second type of small combination display result is derived (15 special A, cherry 1 for each winning line)
When the third type of small role display result is derived, a larger number of game values may be given than when the fourth type of small role display result is derived (special (15 for B, 2 for bell).

  Here, even when the second type of small combination display result or the fourth type of small combination display result is derived, when the first type of small combination display result or the third type of small combination display result is derived, respectively. A player can obtain only a small number of game values. For this reason, in order to obtain a larger number of gaming values, the first procedure or the third type of small role for deriving the first type of small role display result regardless of the determination result of the prior decision means. It is a good idea to operate the stop operation means in the third procedure for deriving the display result, and the player can select the operation procedure.

In the above slot machine,
When the second type of small combination display result or the fourth type of small combination display result is derived, specific game state ending means (step S215) for ending the specific game state is further provided. it can.

  Here, when the second type of small combination display result or the fourth type of small combination display result is derived, the specific gaming state ends. Therefore, in order to prevent the end of the specific gaming state when the first information and the second information are notified by the small role notification means, the first type small role display result is displayed regardless of the determination result of the prior determination means. It is advantageous to operate the stop operation means in the first procedure for deriving or the third procedure for deriving the third kind of small role display result, and the player can select the operation procedure. .

In the above slot machine,
When a predetermined special display result (big bonus (A), big bonus (B), big bonus (C)) is derived as a display result of the variable display device, it is advantageous for a player who is different from the specific gaming state. Special game state control means (steps S208, S210, S212) for controlling the game state to the special game state (big bonus (1), big bonus (2)) is further provided,
The pre-determining means determines whether or not to allow the derivation of the special display result when the special gaming state is not controlled (FIG. 4B),
When the special gaming state control means is not controlled to the special gaming state by the special gaming state control means, the probability (438/65536) that the predetermination means determines that the derivation of the special display result is allowed. The gaming state can be controlled to the specific gaming state only during the number of games (500 games) larger than the reciprocal of).

  In this case, the number of continuing games in the specific gaming state is larger than the expected value of the number of games from the end of the special gaming state to the start of the next special gaming state. For this reason, it is determined that the derivation of the special display result is permitted while the gaming state is controlled to the specific gaming state, and the special display result is derived based on the determination and controlled to the special gaming state. Become more. As a result, there may be a case where a game is played for a long time in a gaming state that is more advantageous to the player than in the normal gaming state, so that the player's expectation can be enhanced and the interest of the game can be improved.

The slot machine is
Special game state control means (steps S208, S210) for controlling the game state to a special game state that is advantageous to a player different from the specific game state until a predetermined end condition is satisfied when a predetermined special transition condition is satisfied. , S212),
The specific game state control means can control the game state to the specific game state after the special game state ends (step S309). In this case,
The slot machine is

Selection effect execution means (steps S413, S457, S463) for executing the type of effect (navigation notification) selected by the effect selection means when controlled to the special gaming state;
When controlled to the special game state, lottery with different winning conditions depending on the type of the effect selected by the effect selecting means (when character A is selected, the special A + special B + special C is won by 1 / 32, lottery means (steps S438, S442, S445 (YES)) for performing a 1/4 selection for watermelon or cherry when selecting character B, and a 100% winning probability for winning for character C when winning a character C; ,
When winning the lottery by the lottery means, the small role notification determining means (steps S414, S446, S464) for determining that notification is made to the small role notification means in the specific game state after the special game state is ended. )When,
When it is determined by the small role notification determining means that notification is to be made, in a mode according to the type of effect selected by the effect selecting means (when the character A is selected, the image of the character A is displayed at the end of the big bonus. An RT navigation notification, when selecting character B, the image of character B when betting the next game, and when selecting character C, the image of character C when winning a prize). And a small role notification determination notification means (steps S413, S457, S463) for notification to
The small role notifying means is provided on the condition that notification is given by the small role notification determining means in the specific gaming state after the special gaming state has ended (step S416), and the prior determination means Thus, information according to the type of the small role display result determined to allow derivation can be notified.

  Here, since the player can select the type of effect executed in the special game state by his / her own operation, the interest of the effect executed in the special game state is improved, and it is interesting to select the type of effect. Will increase. Further, when the special gaming state is controlled, it is determined whether or not notification is made by the small role notification means in the specific gaming state after the special gaming state is ended, and when the determination is made, the special gaming state is determined. In the specific gaming state controlled after the ending, information according to the type of the small combination display result determined to permit derivation is notified.

  Here, when it is determined by the small role notification means in the specific gaming state after the special gaming state is finished, the fact is notified to the player by the small role notification determination notification means. Since the player is also different according to the type of effect selected by the player through his / her own operation, the interest in selecting the type of effect is further increased. Furthermore, whether or not to make a notification by the small role notification means in the specific gaming state after the end of the special gaming state, because the lottery is drawn according to different winning conditions depending on the type of production selected by the player's own operation, The fun of selecting the type of production will be further increased. In addition, the selection of the type of performance in the special game state by the player also affects the progress of the game, that is, the information notification according to the type of the small role display result determined to allow derivation. It is possible to increase the player's sense of intervention in the game, thereby improving the interest of the game.

In the slot machine, information according to the type of the small combination display result determined by the prior determination unit that the small combination notification unit allows derivation until a predetermined period has elapsed in the specific gaming state. If it is to inform
The slot machine is
When it is determined that the derivation of the winning display result is permitted when the predetermination means has not determined that the derivation of the winning display result is permitted when the specific gaming state is controlled Notification period extension determination means (steps S430 and S431) for determining to extend the period of notification by the small role notification means with a higher probability than
According to the determination by the notification period extension determination means, the information processing apparatus further comprises notification period extension means (step S433) for extending a period of notification by the small role notification means when controlled to the specific gaming state. Can do.

  In this case, notification is performed by the small role notification means until a predetermined period elapses in the specific gaming state. When the specific gaming state is controlled, it is determined whether or not to extend the predetermined period. Here, the probability that it is determined to extend the period of notification by the small role notification means is higher when the prior determination means has not determined to allow the derivation of the winning display result, so that the specific game Even if it is not determined that the derivation of the winning display result is permitted by the predetermining means in the state, and the display result derived to the variable display device does not become the winning display result, the player's expectation may be reduced.

  The game control board 101 is a control board on the main side that controls the overall flow of the game in the slot machine 1, and includes a control unit 110 including a CPU 111, a RAM 112, a ROM 113, and an I / O port 114. It is installed. Further, a random number generation circuit 115, a sampling circuit 116, a power supply monitoring circuit 117, a reset circuit 118, and other circuits are mounted.

  The CPU 111 has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, and executes a program (described later) stored in the ROM 113 to perform processing related to the progress of the game, and in the slot machine 1 Control each part of the control circuit directly or indirectly. The RAM 112 is used as a work area when the CPU 111 executes a program. The configuration of the RAM 112 will be described later. The ROM 113 stores programs executed by the CPU 111 and fixed data. The I / O port 114 inputs and outputs control signals to and from each circuit connected to the game control board 101.

  The random number generation circuit 115 is configured by a counter that counts up and updates a value every time a pulse is generated, and the sampling circuit 116 acquires a numerical value counted by the random number generation circuit 115. The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function).

  The power monitoring circuit 117 monitors the power supply voltage supplied from the power supply substrate 100, and outputs a voltage drop signal to the control unit 110 when detecting a voltage drop. Although not particularly shown, the control unit 110 includes an interrupt input terminal connected to the power supply monitoring circuit 117, and an external interrupt is generated in the CPU 111 when a voltage drop signal is input to the interrupt input terminal. The CPU 111 executes a power interruption interrupt process.

  The reset circuit 118 outputs a reset signal when the voltage rises to a level at which the control unit 110 can be activated when the power is turned on to start the control unit 110, and generates a signal periodically output from the control unit 110. When the count is incremented without being cleared based on the reset counter, that is, when the control unit 110 does not operate for a certain time, a reset signal is output to the control unit 110 and the control unit 110 is restarted. .

  The CPU 111 also has a function of updating the numerical value of the specific address in the RAM 112 by timer interrupt processing and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function). The CPU 111 transmits various commands to the effect control board 102 via the I / O port 114. Note that information (commands) is sent from the game control board 101 to the effect control board 102 only in one direction, and no information (commands) is sent from the effect control board 102 to the game control board 101.

  Connected to the game control board 101 are a single BET switch 45, a MAXBET switch 46, a start switch 41, stop switches 42L, 42C, 42R, a settlement switch 47, a first reset switch 48, and a throw-in medal sensor 44. Detection signals from the switches / sensors are input. In addition, detection signals of the reel sensors 3SL, 3SC, and 3SR are input via the reel relay substrate 103. In accordance with the detection signals of these switches / sensors input via the I / O port 114 or the detection signals of various switches input via the power supply board 100 as described above, the CPU 111 on the game control board 101 Processing is in progress.

  The game control board 101 also includes a flow path switching solenoid 49, a game number display 51, a credit display 52, a payout display 53, a loading instruction lamp 59, a single betting lamp 54, two betting lamps 55, 56, Three betting lamps 57 and 58, a game over lamp 63, a start lamp 60, a replay lamp 62, BET button lamps 70a and 70b, and operation valid lamps 63L, 63C, and 63R are connected, and the CPU 111 follows the progress of the game. These operations are controlled.

  The game control board 101 is connected to reel motors 3ML, 3MC, and 3MR via a reel relay board 103. The CPU 111 controls the reel motors 3ML, 3MC, 3MR via the reel relay substrate 103 and stops the reels 3L, 3C, 3R with reference to a winning flag set in the RAM 112 by an internal lottery to be described later. An effect control board 102 is further connected to the game control board 101 via an effect relay board 106.

  The effect relay board 106 is a board provided to ensure one-way information transmitted from the game control board 101 to the effect control board 102. The effect relay board 106 does not check the game control board 101 and the effect control board 102 by checking this state, and an illegal signal (especially an external input to the effect control board 102 is input to the control unit 110 of the game control board 101). It is possible to check whether or not a modification has been made such that a signal is input).

  The effect control board 102 is a sub-side control board that controls the execution of effects in the slot machine 1, and is equipped with a control unit 120 including a one-chip microcomputer including a CPU 121, a RAM 122, a ROM 123, and an I / O port 124. Yes. In addition, the random number generation circuit 125 and the sampling circuit 126 are mounted, and the CPU 121 obtains the value counted by the random number generation circuit 125 by the sampling circuit 126, so that the hardware random number function similar to that of the game control board 101 is obtained. Is forming. It also has a software random number function by interrupt processing.

  The CPU 121 executes a program (described later) stored in the ROM 123 to perform processing related to the execution of the effect, and controls each circuit in the effect control board 102 and each circuit connected thereto. The performance is performed based on a command received from the game control board 101 via the I / O port 124. The RAM 122 is used as a work area when the CPU 121 executes a program. The configuration of the RAM 122 will be described later. The ROM 123 stores programs executed by the CPU 121 and fixed data. The effect data stored in the ROM 123 will be described later. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

  The effect control board 102 is connected with game effect lamps 75A to 75M, a liquid crystal display 4, speakers 7L, 7R, and 7U, a fluorescent lamp 6, a weight lamp 61, and a bonus notification lamp 66. A reel lamp 3LP is connected via a reel lamp relay substrate 104. The control unit 120 of the effect control board 102 performs these effects by controlling these parts.

  The reel relay board 103 relays between the game control board 101, the external output board 105 and the reel unit 3. The reel relay substrate 103 is also connected with a full sensor 90, and its detection signal is input. The full tank sensor 90 is provided inside the slot machine 1 and detects that the medals in the overflow tank storing the medals overflowed from the hopper 80 are full.

  The reel lamp relay board 104 relays between the effect control board 102 and the reel unit 3. The external output board 105 is connected to an external device such as a hall management computer and receives a big bonus medium signal, regular bonus medium signal, reel control signal, stop signal input from the game control board 101 via the reel relay board 103. The switch signal, medal IN signal, medal OUT signal, and winning status signal are output to the external device.

  In the slot machine 1, a winning is awarded when the winning symbols are arranged on any winning line of the variable display device 2. The type of winning combination is determined according to the gaming state. As the gaming state, in addition to the normal gaming state, the big bonus (1) and the big bonus (2) as the special gaming state, and the winning probability of replay than the normal gaming state (winning probability of replays 1 to 4 described later) RT as a high probability state of replay where the sum of

  The types of winning combinations are broadly divided into special roles with transition to special gaming status (big bonus (1), big bonus (2)), small roles with payout of medals, and the number of bets There is a re-player who can start the next game without setting. FIG. 4A is a diagram for explaining the combination of the types of winning combinations in the slot machine 1 and the symbols in the variable display device 2.

  The big bonus (A) is awarded when a combination of “BAR-BAR-BAR” is aligned on any winning line in the normal gaming state or RT. When winning the big bonus (A), the gaming state shifts from the normal gaming state to the big bonus (1). The big bonus (B) is won when a combination of “red 7-red 7-red 7” is arranged in any winning line in the normal gaming state or RT. The big bonus (C) is won when a combination of “yellow 7-yellow 7-yellow 7” is arranged on any winning line in the normal gaming state or RT. When the big bonus (B) or the big bonus (C) is won, the gaming state shifts to the big bonus (2).

  In the big bonus (1) or the big bonus (2), the regular bonus is repeatedly provided until the end. The big bonus (1) flag is set in the RAM 112 while the gaming state is the big bonus (1), and the big bonus (2) flag is set in the RAM 112 during the big bonus (2). Further, during the regular bonus provided in the big bonus (1) or the big bonus (2), the regular bonus medium flag is set in the RAM 122.

  The regular bonus for a single bonus offered by Big Bonus (1) or Big Bonus (2) will be either when 12 games are consumed or when 6 games are won (any kind of role is allowed), whichever comes first End with. The big bonus (1) ends when the number of medals paid out to the player exceeds 120. The big bonus (2) ends when the number of medals paid out to the player exceeds 400. Since the maximum number of payouts per game is 15, the upper limit of the number of payout medals in the big bonus (1) and the big bonus (2) is 135 and 415, respectively.

  Also, after the big bonus (1) or the big bonus (2) is finished, the gaming state is controlled to RT only for the subsequent 500 games (however, the big bonus (A), the big bonus (B), the big bonus) Bonus (C), until you win a bell or cherry). Note that RT is terminated when a big bonus (A), big bonus (B), or big bonus (C) is won in RT.

  Even if the big bonus (A), big bonus (B), or big bonus (C) is won in the internal lottery to be described later, “red 7”, “yellow 7”, “BAR” are displayed for the reels 3L, 3C, 3R. Since they are not arranged at intervals of 5 frames or less, depending on the operation procedure of the stop buttons 12L, 12C, 12R, there is a case where these winning combinations are not won.

  A watermelon is awarded when a combination of “watermelon-watermelon-watermelon” is aligned on any winning line in any gaming state, and five medals are paid out. Since the “watermelons” for the reels 3L, 3C, and 3R are not arranged at intervals of 5 frames or less, even if the watermelon is won in the internal lottery that will be described later, the operation of the stop buttons 12L, 12C, and 12R Depending on the procedure, you may not win.

  Bell wins when any combination of "Bell-Bell-ANY" (ANY indicates any kind of symbol) is available on any winning line in any game state. Will be paid out. For the inner reel 3C, “bells” are arranged at intervals of 5 frames or less, but for the left reel 3L, only one “bell” is arranged. Even if it is, there is a case where no prize is awarded depending on the operating procedure of the stop buttons 12L and 12C. When the stop button 12L is operated at the timing when “yellow 7” or “BAR” is displayed for the left reel 3L, “Bell” is not within the drawing range of 5 frames and wins the bell. There is nothing.

  Cherry is awarded when the symbol “cherry” is derived on any of the winning lines for the left reel 3L in any gaming state, and one medal is paid out per winning line. When “cherry” is stopped at the upper or lower stage of the left reel 3L, the medals are paid out in total because two lead lines are derived. Since only two “cherries” are arranged for the left reel 3L, there is a case where no winning is made depending on the operation procedure of the stop button 12L. If the stop button 12L is operated at the timing when “red 7” is displayed for the left reel 3L, “cherry” is not within the drawing range of 5 frames, and no cherry is won.

  Special A is awarded when a combination of “red 7-bell-bell” is aligned on any winning line in any gaming state. Special B is awarded when a combination of “yellow 7-bell-bell” is aligned on any winning line in any gaming state. Special C is awarded when a combination of “BAR-Bell-Bell” is aligned on any winning line in any gaming state. If one of Special A to Special C is won, 15 medals are paid out.

  For the middle and right reels 3C and 3R, “bells” are arranged at intervals of 5 frames or less, but for the left reel 3L, “red 7”, “yellow 7” and “BAR” are spaced from each other by 7 frames. Depending on the operation procedure of the stop buttons 12L, 12C, 12R, even if you win special A, special B or special C in the internal lottery described later, you will not win any of these roles. There is. However, in the regular bonus (provided with Big Bonus (1) or Big Bonus (2)), Special A, Special B, and Special C are won at the same time. As long as the game is stopped for the first time, a special A, special B, or special C will be awarded.

  Replay is awarded when a combination of “JAC-JAC-JAC” is aligned on any winning line in the normal gaming state or RT. When a replay is won, there is no payout of medals, but the next game can be started again without setting the number of bets, so 3 medals corresponding to the number of bets 3 that are not required to be set in the next game are paid out Is essentially the same. Since “JAC” is arranged at intervals of 5 frames or less for all of the reels 3L, 3C, and 3R, when the replay is selected alone, the operation procedure of the stop buttons 12L, 12C, and 12R is concerned. Without winning.

  As will be described later, in the state where the winning of big bonus (A), big bonus (B) or big bonus (C) is carried over, for small roles (watermelon, bell, cherry, special A to special C) or replay May win. The replay is derived in preference to the big bonus (A), the big bonus (B), or the big bonus (C), so there is no loss, but the big bonus (A), big bonus (B ) Or derivation of the big bonus (C) is given priority.

  Hereinafter, the internal lottery will be described. The internal lottery is to determine whether or not the winning of each combination described above is permitted before the display result of the variable display device 2 is derived and displayed (actually, when the start lever 11 is operated). . In the internal lottery, a random number for internal lottery (an integer from 0 to 65535) is acquired from the random number generation circuit 115. Then, for each combination determined according to the gaming state, the acquired random number for internal lottery, the number of bets set by the player, and each combination determined according to the set value set by the setting switch 91 This is performed according to the number of judgment values. Winning in the internal lottery is exclusive.

  In the internal lottery, the number of judgment values registered for each game state and set value for each combination is sequentially added to the random number for internal lottery. It is judged that it was won. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is registered in the ROM 113 in the winning combination table by gaming state.

  FIG. 4B is a view showing a winning combination table by gaming state. The winning combination table by game state is stored in advance in the ROM 113, and is a table in which the number of determination values for each lottery target for each gaming state in the internal lottery is registered. Here, only a predetermined set value is shown, but a slightly different value is registered according to a difference in the set value. In the internal lottery, there are cases where a plurality of winning combinations are simultaneously targeted for lottery, such as special A + special B + special C.

  In accordance with this winning state-specific winning table, in the internal lottery, Big Bonus (A), Big Bonus (B), Big Bonus (C), Watermelon, Bell, Cherry, Special A + Special B + Special C, Special A, Special B, The number of special C and replay determination values is acquired in order according to the gaming state.

  However, for the regular bonus game state provided by Big Bonus (1) or Big Bonus (2), Big Bonus (A), Big Bonus (B), Big Bonus (C), Watermelon, Bell, Cherry , Special A, special B, special C, and replay judgment value number 0 is registered, so these roles will not be won (however, special A to special C are special A + special B + special C You may win at the same time.

  In the setting value in the example of FIG. 4B, the total number of determination values of the big bonus (A), the big bonus (B), and the big bonus (C) in the normal gaming state or RT is 408. The probability of winning either the big bonus (A), the big bonus (B), or the big bonus (C) is 438/65536. The reciprocal 65536/408 (≈149.6) is smaller than the RT continuous game number 500. Even in other setting values, the reciprocal of the probability of winning either the big bonus (A), the big bonus (B), or the big bonus (C) is larger than the number of continuing games of RT.

  Also, the number of replay determination values in the normal gaming state and RT is the same regardless of the set value. However, the number of replay determination values is 8932 in the normal gaming state, whereas it is 50604 in RT. That is, the winning probability of replay in the normal gaming state is approximately 1 / 7.3, but the winning probability of replay in RT is approximately 1 / 1.4.

  By setting the replay total winning probability in this way, in the normal gaming state, the medal payout rate is smaller than 1 (that is, the internal lottery with respect to the number of medals to be inserted for setting the bet number). In RT, the medal payout rate is greater than 1 (ie, the number of bets) because the total winning probability of replay is higher in RT, although the number of medals to be paid out for the winning combination is smaller. The number of medals to be paid out for the small role won in the internal lottery is larger than the number of medals to be inserted for the setting of). However, the medal payout rate in RT is also smaller than the medal payout rate in the regular bonus provided by the big bonus (1) or the big bonus (2). The relationship of the medal payout rates according to the gaming state described here is the same when the set value is any of 1-6.

  Next, stop control of the reels 3L, 3C, 3R will be described. The reels 3L, 3C, and 3R constituting the variable display device 2 rotate on condition that the start lever 11 is operated and a predetermined time has passed since the start of rotation of the reels 3L, 3C, and 3R in the previous game. Be started. When the stop buttons 12L, 12C, and 12R are operated by the player, the corresponding reels 3L, 3C, and 3R are within the maximum stop delay time range of 190 milliseconds (4 frames pull-in range). In)).

  The reels 3L, 3C and 3R stop rotating so that the winning symbol set in the winning line is aligned on the winning line within the range of the maximum stop delay time of 190 milliseconds, and the maximum stop of 190 milliseconds It is controlled so that the symbol of the combination for which the winning flag is not set within the delay time is not aligned on the winning line.

  Here, when the stop button 12C, 12R is operated prior to the stop button 12L in the case where the cherry is won, the symbol “Bell” is tempered on the winning line. If the stop button 12L is last operated at a timing at which the symbol “cherry” can be derived to the left reel 3L (timing at which the symbols 1 to 14 are positioned in the lower stage), “cherry” is derived, Otherwise, the kicking control is performed so that the “red 7” of No. 18 is not stopped on the winning line where the “bell” is tempered.

  On the other hand, when the stop button 12L is operated for the first time when the cherry is selected, the timing at which the symbol “cherry” can be derived to the left reel 3L (timing at which the symbols 1 to 14 are positioned in the lower stage) If so, pull-in control is performed so that “cherry” is derived, and if not, the reel 3L is stopped at the symbol position at that time. When “red 7” is derived to the left reel 3L, kick control is performed so that the special A is not won when the reels 3C and 3R are stopped.

  If the stop button 12C, 12R is operated before the stop button 12L in the case where the bell is won, the symbol “Bell” is displayed on the winning line (at least in the middle of the reel 3L, the “Bell” "To stop)). The last time the stop button 12L was operated is the timing at which the “bell” symbol of the left reel 3L can be derived on the winning line where the symbol is placed (the timing at which symbols 17 to 0 are located on the winning line). If there is, align the “bell” on the winning line, otherwise control the kicking so that the 4th “yellow 7” and the 11th “BAR” will not stop on the winning line where the “bell” is tempered. Is done.

  On the other hand, when the stop button 12L is operated for the first time when the bell is won, the timing at which the “bell” symbol can be derived to the left reel 3L (timing at which the symbols 15 to 0 are located in the lower stage) If so, the pull-in control is performed so that the “bell” is derived, and if not, the reel 3L is stopped at the symbol position at that time. When “bell” is derived to the left reel 3L, the “bell” symbol is controlled to be drawn so that the bell is awarded when the reel 3C is stopped. When “yellow 7” or “BAR” is derived to the left reel 3L, kick control is performed so that the special B or special C is not won when the reels 3C and 3R are stopped.

  When the big bonus (A) winning flag, the big bonus (B) winning flag, or the big bonus (C) winning flag and the replay winning flag are set in duplicate, the replay symbol is given priority on the winning line. Controlled to align. Regardless of the operation procedure of the stop buttons 12L, 12C, and 12R, the replay is won. In this case, the big bonus (A), the big bonus (B), or the big bonus (C) is not won.

  If the big bonus (A) winning flag, big bonus (B) winning flag or big bonus (C) winning flag and watermelon winning flag or bell winning flag are set in duplicate, the big bonus (A), big Control is performed so that the bonus (B) or big bonus (C) symbols are preferentially aligned on the winning line. If the symbols of big bonus (A), big bonus (B), or big bonus (C) cannot be aligned on any winning line by operating the stop buttons 12L, 12C, 12R, Alternatively, when “bell” can be aligned on the winning line, “watermelon” or “bell” can be aligned on the winning line, and the watermelon or bell can be awarded.

  When the big bonus (A) winning flag, the big bonus (B) winning flag, or the big bonus (C) winning flag and the cherry winning flag are set in duplicate, the big bonus (A), the big bonus (B) Alternatively, control is performed so that the big bonus (C) symbol is preferentially aligned on the winning line. If the symbols of Big Bonus (A), Big Bonus (B), or Big Bonus (C) cannot be aligned on any winning line by operating the stop buttons 12L, 12C, 12R, the left reel If “cherry” can be derived to the upper or lower stage of 3L, “cherry” is derived to the upper or lower stage and the cherry is awarded.

  If the Big Bonus (A) Winning Flag, Big Bonus (B) Winning Flag or Big Bonus (C) Winning Flag and Special A Winning Flag, Special B Winning Flag or Special C Winning Flag are set in duplicate, First, control is performed so that the symbols of the big bonus (A), the big bonus (B), or the big bonus (C) are preferentially aligned on the winning line. If the symbols of Big Bonus (A), Big Bonus (B), or Big Bonus (C) cannot be aligned on any winning line due to the operating procedure of the stop buttons 12L, 12C, 12R, special A to special Control is performed so that the symbol C is preferentially aligned on the winning line.

  Note that the stop control of the reels 3L, 3C, and 3R described above is based on the stop operation position of the reels that have not yet stopped according to the gaming state and the setting state of the winning flag (and the symbols derived for the reels that have already stopped). A stop control table that defines the relationship between the stop position and the stop position is created in advance for unreacted reels, and when the stop buttons 12L, 12C, and 12R are operated, the stop control table created in advance is referred to and The rotation of the reel to be stopped is to be stopped. In the stop control table, the stop position is uniquely determined with respect to the stop operation position.

  On the game control board 101 side, the internal lottery is performed as described above, and the rotation of the reels 3L, 3C, 3R is stopped according to the result and the operation timing of the stop buttons 12L, 12C, 12R, and a prize is generated. It will be a thing. As a result of winning a prize, a medal is paid out or a game state is transferred as a payout. In this way, depending on the progress of the game on the game control board 101 side, an original effect is performed on the effect control board 102 side. Is called. In order to perform such an effect, the CPU 121 of the effect control board 102 must be able to recognize the progress of the game on the game control board 101 side. Is transmitted from the game control board 101 to the effect control board 102.

  The commands transmitted from the game control board 101 to the effect control board 102 include at least a BET command, a winning status notification command, a winning information command, and a game state command. The commands transmitted from the game control board 101 to the effect control board 102 include other commands, but since they are not directly related to the present invention, a detailed description thereof is omitted.

  The BET command indicates that the bet number for one game has been determined, and is transmitted when 3 is set as the bet number (including automatic setting based on a replay winning). The winning status notification command indicates the setting status of the winning flag in the RAM 112, and is transmitted when the start lever 11 is operated and an internal lottery is performed. The winning information command indicates the type of winning generated according to the display result of the variable display device 2 and the number of medals to be paid out with the winning. The display result is derived to the variable display device 2 and the winning determination is made. Sent when done. The gaming state command indicates a gaming state to be applied in the next game, and is transmitted at the end of one game.

  The CPU 121 of the effect control board 102 performs various effects based on the commands sent from the CPU 111 of the game control board 101 as described above. As such effects, game navigation performed when winning a bell, cherry, special A, special B, or special C with RT controlled after the big bonus (1) or big bonus (2) ends, There is a navigation notification that notifies the player that the right of game navigation is to be notified to the player at RT. The navigation notification is performed when the gaming state is the big bonus (1) or the big bonus (2), and is a part of the effect during the big bonus.

  In addition, the game navigation is performed when the right of the game navigation is left in the game in which the game state is RT and the bell, cherry, special A, special B or special C is won. When the cherry or special A is selected, the background of the image displayed on the liquid crystal display 4 is changed to red, and when the bell or special B is selected, the background is displayed on the liquid crystal display 4. When the background of the image is changed to yellow and the special C is won, the background of the image displayed on the liquid crystal display 4 is changed to black.

  Here, in the game navigation based on the black background image, the player can know that the special C is won. If you win the Special C as it is, 15 medals will be paid out and the RT will not be terminated (although the fact that you did not win the Special C does not end the RT). . Further, if the right of game navigation remains, the game navigation will be performed even if the next bell, cherry, special A, special B or special C is won.

  On the other hand, in the game navigation based on the red background image, the player cannot know whether the player has won the cherry or the special A. Of course, only two medals are paid out at maximum in the Cherry prize, but 15 medals are paid out in the Special A prize. Also, if you win the cherry, the RT will end, but if you win the special A, the RT will not be terminated, and if you still have the right of game navigation, the next bell, cherry, special A, Even if special B or special C is won, game navigation is performed.

  Further, in the game navigation based on the yellow background image, the player cannot know whether the player has won the bell or the special B. However, only two medals are paid out in the Bell prize, but 15 medals are paid out in the Special B prize. Also, if you win the bell, the RT will end, but even if you win the special B, the RT will not be terminated, and if you still have the right of game navigation, the next bell, cherry, special A, Even if special B or special C is won, game navigation is performed.

  Information regarding the winning of the small role that is notified by changing the background color of the image displayed on the liquid crystal display 4 in the game navigation based on the red or yellow background image in this way, If the stop buttons 12L, 12C, and 12R are operated in such a procedure, it is not possible to specify whether or not a prize can be won. However, for example, when a game navigation is performed with a red background image, from the viewpoint of the expected value of the number of medals to be paid out, or from the viewpoint of whether or not RT advantageous to the player is continued, It is possible to understand which of the roles whose notified information indicates the possibility of winning is better.

  In this manner, the determination as to whether or not to give the player the right of game navigation performed in the RT gaming state is first made when the gaming state has a big bonus (1) or a big bonus (2). When it is determined that a game navigation right is to be granted, a navigation notification is made as part of the big bonus production. There are three types of triggers for determining whether or not to grant game navigation rights in the gaming state of the big bonus (1) or the big bonus (2). Alternatively, it is selected by the player at the start of the big bonus (2).

  That is, before the first game of the big bonus (1) or the big bonus (2) is started, the three types of characters A, B, and C are switched and displayed on the liquid crystal display 4 for a certain period of time. The character switching display is stopped at the timing when the player performs the operation of determining the bet number for the first game of 1) or the big bonus (2). The type of the character stopped here is an opportunity for determining whether or not to give the player the right of game navigation.

  When the character A is selected, if the winning probability is 54100/65536 special A + special B + special C, a navigation lottery for determining whether or not to give game navigation rights is performed. The winning probability of the navigation lottery here is 1/32. In addition, even if the navigation lottery in this case is won, the navigation notification is not performed immediately, and at the end of the big bonus (1) or the big bonus (2), the liquid crystal display 4 is displayed as a part of the effect during the big bonus. An image of the character B is displayed and navigation notification is performed.

  When the character B is selected, if a winning probability is 6200/65536 or a watermelon whose winning probability is 300/65536, a navigation lottery is performed to determine whether or not to grant the right of game navigation. . The winning probability of the navigation lottery here is ¼. Also, if you win the navigation lottery in this case, if you have won the cherry or watermelon here, when the number of bets set for the next game has been confirmed, As an example, the image of the character B is displayed on the liquid crystal display 4 and the navigation notification is performed.

  When the character C is selected and the winning probabilities are won for 1640/65536 bells, it is determined that the right of game navigation is given with a probability of 100% without going through the navigation lottery. However, the navigation notification is not performed only by winning the bell, and when the player actually wins the bell based on the winning of the bell, the image of the character C is displayed on the liquid crystal display 4 as a part of the effect during the big bonus. Navigation notification will be performed.

  When the navigation lottery while being controlled by the big bonus (1) or the big bonus (2) is won (or the character C is selected and the bell is won), and the right of game navigation is given to the player The player is given the right to perform game navigation for five games as an initial value. However, the number of games with the right of game navigator is incremented by one when winning the navigation addition lottery performed in each RT game when the right remains, and succeeds in double-up that is tried by the player's selection. Is doubled.

  The navigation addition lottery is performed in each game if the game state is RT and the right of game navigation still remains in one game. However, the winning probability of the navigation addition lottery is not uniform, the winning probability is 1/32 when all the roles are lost, and the winning probability when one of the winning combinations is 1/32. It is very high compared to 16384.

  Also, before the game immediately after the end of the big bonus (1) or the big bonus (2) is started, the three types of characters 1 and 2 are switched and displayed on the liquid crystal display 4 for a certain period of time, and the big bonus (1 ) Or the character switching display is stopped at the timing when the player performs an operation of determining the bet number for the game immediately after the end of the big bonus (2). If the type of the character stopped here is character 1, it is decided to try to double up the number of games with the right of game navigation.

  If it is decided to try to double-up the number of games in the right of game navigator, games such as those mentioned above will be used for games that are first won at Bell, Cherry, Special A, Special B or Special C in RT. Navigation is not performed, and the background color of the image displayed on the liquid crystal display 4 is changed to a red, yellow, and black stripe pattern. In this case, if the stop button 12L is operated at a timing capable of winning the special A, the special B or the special C is never won. Similarly, if the stop button 12L is operated at the timing when the special B can be won, the special C or the special A will not be won. If the stop button 12L is operated at the timing when the special C can be won, the special button You will never win A or Special B.

  In this way, even if the operation timing of the stop button 12L for winning special A, special B or special C is not known, if special A, special B or special C can be won, The number of games with the right of game navigation will be doubled. When the navigation addition lottery is won in the game before trying to double up, the number of games of the game navigation right including the number of added games is doubled.

  The RAM 122 of the effect control board 102 is provided with an area for a navigation counter that counts the number of remaining games for game navigation rights. When the character A or the character B is selected in the big bonus (1) or the big bonus (2), if winning at the time of the navigation lottery, the navigation notification is not performed immediately. However, an area for setting an A notification flag and a B notification flag indicating that the navigation notification has not been performed is also provided in the RAM 122.

  In addition, a double-up selection flag that is set when a trial to double-up is selected immediately after the big bonus (1) or big bonus (2) is completed, or a case of selecting to try double-up. An area for setting a double-up notification flag that is set when the first bell, cherry, special A, special B, or special C win in RT is informed and the success / failure of double-up is not yet known. Is also provided in the RAM 122.

  Furthermore, since it is necessary to determine the presence / absence of a prize in the RAM 122 of the effect control board 102 other than the timing at which the prize information command is received, the prize information indicated by the prize information command received from the game control board 101 is stored. An area is also provided. Further, since it is necessary to determine the game state other than the timing at which the game state command is received, an area for storing the game state indicated by the game state command received from the game control board 101 is also provided. For a specific gaming state, it is necessary not only to be controlled by the game (or next game), but also to determine whether it will start or end, so the area for saving the gaming state is Two games are provided.

  Hereinafter, a gaming operation in the slot machine 1 according to this embodiment will be described. In the following description, the term “game” means, in a narrow sense, from the operation of the start lever 11 until the reels 3L, 3C, 3R are stopped. However, when a game is played, the number of bets before the operation of the start lever 11 is set, and medals are paid out and the game state is shifted after the reels 3L, 3C, 3R are stopped. Is also included in the “game” in a broad sense. In the following description, descriptions of processes not related to the present invention may be omitted.

  FIG. 5 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S1).

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. A BET process for instructing the start is performed (step S2). If the player has won a replay in the previous game, the same number of bets as in the previous game (3 in this embodiment) is automatically set by the replay game flag (the replay game flag is erased at this stage). ). When the bet number is confirmed in the BET process (that is, when 3 is set as the bet number), a BET command indicating the confirmation of the bet number is transmitted to the effect control board 102.

  When the number of bets is set by the BET process and the start lever 11 is operated, a random number for internal lottery is extracted, and winning to each combination determined according to the gaming state is allowed based on the extracted random number value A lottery process for determining whether or not to perform is performed (step S3). In the lottery process, a winning status notification command indicating the setting status of the winning flag in the RAM 112 is transmitted to the effect control board 102. Details of the lottery process will be described later.

  When the lottery process is completed, a reel rotation process is performed (step S4). In the reel rotation process, the reel motor is operated on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, and 3R in the previous game. 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. When predetermined conditions (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reels 3L, 3C, 3R are satisfied, the stop buttons 12L, 12C, 12R Is enabled. Thereafter, when the stop buttons 12L, 12C, and 12R are operated by the player, the driving of the reel motors 3ML, 3MC, and 3MR is stopped according to the setting state of the winning flag, and the rotation of the reels 3L, 3C, and 3R is stopped. .

  When the driving of each of the reels 3L, 3C, and 3R is stopped, a winning determination process is performed to determine whether any of the above-mentioned role symbols is derived and displayed on any winning line in the display mode at the time of stopping. (Step S5). If it is determined in this winning determination process that a winning combination has been won, various processes corresponding to the winnings generated on the game control board 101 are performed. Here, a winning information command indicating a winning determination result is sent to the effect control board 102. Details of the winning determination process will be described later.

  When the winning determination process ends, a payout process is performed (step S6). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. In addition, various processes that are not related to winning (for example, a process related to the end control of the big bonus and the deletion of a winning flag that does not carry over) are also performed. At the end of the payout process, that is, at the end of one game, a game state command indicating the game state of the next game is sent to the effect control board 102. Details of the payout process will be described later. Then, the process for one game ends, and the process for the next one game starts.

  Next, the lottery process in step S3 will be described in detail. FIG. 6 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S3. In the lottery process, it is determined whether or not the gaming state is the big bonus (1) or the big bonus (2) depending on whether or not the big bonus flag is set in the RAM 112 (step S101). If the gaming state is neither the big bonus (1) nor the big bonus (2), the process proceeds to step S104 as it is.

  If the gaming state is the big bonus (1) or the big bonus (2), it is determined whether or not the gaming state is the regular bonus depending on whether or not the regular bonus medium flag is set in the RAM 112 (step S102). If the game state is not a regular bonus, it is the first game of the big bonus (1) or big bonus (2), or the regular bonus for one set in the big bonus has ended and the big bonus has not yet ended. Since there is no game, the regular bonus medium flag is set in the RAM 112, and the gaming state is controlled to the regular bonus (step S103). Then, the process proceeds to step S104. If the gaming state is a regular bonus, the process proceeds to step S104 as it is.

  In step S <b> 104, the random number generated by the random number generation circuit 115 is output by the sampling circuit 116 by outputting a sampling command, and is stored in the determination area provided in the RAM 112. The random numbers for the internal lottery may be used after being processed in a predetermined procedure by software instead of using the random numbers extracted from the random number generation circuit 115 as they are.

  Next, in correspondence with the current gaming state, the lottery target combination registered in the winning combination table according to gaming state in FIG. 4B is sequentially read (step S105). Next, the number of determination values corresponding to the gaming state and setting value read for the lottery target combination is acquired (step S106). Then, the acquired number of determination values is added to the internal lottery random value stored in the determination area of the RAM 112, and the result of the addition is used as a new internal lottery random value (step S107). Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the value of the random number for internal lottery (step S108).

  If no overflow has occurred, it is determined whether there is a combination that has not yet been processed among the lottery targets in the gaming state (step S109). If there is something that has not yet been processed, the process returns to step S105, and the process continues with the next lottery target registered in the winning combination table by gaming state as the processing target. If there is nothing not to be processed, the process proceeds to step S113.

  When an overflow occurs, it is determined whether the lottery target combination read in the previous step S105 is any of the big bonus (A), the big bonus (B), or the big bonus (C) (step S110). . If none of the big bonus (A), big bonus (B), and big bonus (C) is found, the process proceeds to step S112.

  If it is any of the big bonus (A), big bonus (B), or big bonus (C), the big bonus (A) winning flag, the big bonus (B) winning flag, or the big bonus (C) winning flag is already stored in the RAM 112. Is set (that is, it is carried over from the previous game) (step S111). If the big bonus (A) winning flag, the big bonus (B) winning flag, or the big bonus (C) winning flag is set, the process proceeds to step S113.

  If none of the big bonus (A) winning flag, the big bonus (B) winning flag, and the big bonus (C) winning flag are set, the process proceeds to step S112. In step S114, the winning flag of the lottery target combination read in the immediately preceding step S105 is set in the RAM 112. Here, the winning combination is not any of the big bonus (A), the big bonus (B), or the big bonus (C), and the big bonus (A) winning flag, the big bonus (B) winning flag or the big bonus (C ) If the winning flag is set, the winning flag for the current lottery target is overlapped with the already set big bonus (A) winning flag, big bonus (B) winning flag or big bonus (C) winning flag. Set. For example, when the lottery target combination is special A + special B + special C, a special A winning flag, a special B winning flag, and a special C winning flag are set. Then, the process proceeds to step S113.

  In step S <b> 113, a winning status notification command is generated according to the setting status of the winning flag in the RAM 112, and is transmitted to the effect control board 102. Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the winning determination process in step S5 will be described in detail. FIG. 7 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S5. In the winning determination process, the winning combination corresponding to the gaming state is read in order from the beginning (step S201). Next, it is determined whether or not the symbol combination of the read combination is aligned with any of the five winning lines of the variable display device 2 (step S202).

  If the combination of symbols for the combination is complete, a winning flag for the combination is set in the RAM 112 (step S203), and the process proceeds to step S204. If the symbol combination of the combination is not complete, the process proceeds to step S204 as it is. In step S204, it is determined whether there is a combination that has not yet been determined as a winning determination among the combinations corresponding to the gaming state. If there is a winning combination that has not yet been determined for winning, the process returns to step S201, and the next winning combination corresponding to the gaming state is read out.

  If all of the winning combinations corresponding to the gaming state are the targets of winning determination, it is next determined whether or not the replay has been won based on whether or not the replay winning flag is set in the RAM 112 (step S205). If the replay has been won, a replay game in-progress flag is set in the RAM 112 (step S206). The replay game in-progress flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S216.

  If the replay has not been won, it is determined whether or not the big bonus (A) has been won depending on whether or not the big bonus (A) winning flag is set in the RAM 112 (step S207). If the big bonus (A) is won, the big bonus (1) medium flag is set in the RAM 112 and the big bonus (A) winning flag set in the RAM 112 is deleted. Further, the RT counter value of the RAM 112 is initialized to 0 (step S208). Then, the process proceeds to step S216.

  If the big bonus (A) has not been won, it is determined whether or not the big bonus (B) has been won according to whether or not the big bonus (B) winning flag is set in the RAM 112 (step S209). If the big bonus (B) has been won, the big bonus (2) medium flag is set in the RAM 112 and the big bonus (B) winning flag set in the RAM 112 is erased. Further, the RT counter value of the RAM 112 is initialized to 0 (step S210). Then, the process proceeds to step S216.

  If the big bonus (B) has not been won, it is determined whether or not the big bonus (C) has been won according to whether or not the big bonus (C) winning flag is set in the RAM 112 (step S211). If the big bonus (C) has been won, the big bonus (2) medium flag is set in the RAM 112 and the big bonus (C) winning flag set in the RAM 112 is erased. Further, the RT counter value of the RAM 112 is initialized to 0 (step S212). Then, the process proceeds to step S216.

  If the big bonus (C) has not been won, it is determined whether or not the gaming state in the current game is RT based on whether or not the value of the RT counter is 0 (step S213). If the game state in this game is not RT, the process proceeds to step S216 as it is.

  When the game state in this game is RT, it is determined whether or not a bell or a cherry is won depending on whether or not a bell or cherry winning flag is set in the RAM 112 (step S214). If either the bell or cherry is won, the RT counter value is initialized to 0 (step S215). Then, the process proceeds to step S216.

  In step S216, winning information indicating the type of winning combination based on the winning flag set in the RAM 112 (however, in the case of losing, the winning flag is not set) and the number of medals to be paid out with the winning. A command is generated and transmitted to the effect control board 102. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S6 will be described in detail. FIG. 8 is a flowchart showing in detail the payout process executed by the CPU 111 in step S6. In the payout process, it is determined whether or not there has been a small role winning accompanied by paying out medals depending on whether or not a winning flag of watermelon, bell, cherry, special A to special C is set in the RAM 112 (step S301). If the small role is not won, the process proceeds to step S303 as it is.

  If the small role winning is achieved, the number of medals is sequentially paid out by controlling the hopper 80. However, until the number of credits accumulated as data reaches 50, instead of paying out medals, the number of credits is increased (step S302). Then, the process proceeds to step S303.

  In step S303, whether or not the game state of the game is the big bonus (1) or the big bonus (2) is determined depending on whether the big bonus (1) medium flag or the big bonus (2) medium flag is set in the RAM 112. judge. However, when the big bonus (A), big bonus (B) or big bonus (C) winning flag is set in the RAM 112, the big bonus (A), big bonus (B) or big bonus in the game is set. Since the bonus (C) is won and the game state of the game is not the big bonus (1) or the big bonus (2), the big bonus (1) medium flag or the big bonus (2) medium flag Is set, the big bonus (1) or the big bonus (2) is not determined.

  When it is determined that the game state of the game is the big bonus (1) or the big bonus (2), the big bonus (2) is started even with the big bonus (1) by the counter provided in the RAM 112. The total number of medals paid out from is counted (step S304). As a result of this count, it is determined whether or not the total number of medals paid out exceeds 120 (step S305). If the total number of medals paid out does not exceed 120, the process proceeds to step S310.

  If the total number of medals paid out exceeds 120, it is determined whether or not the game state of the game is a big bonus (1) (step S306). If it is a big bonus (1), the big bonus (1) is ended here, and the process proceeds to step S308. If it is not the big bonus (1) but the big bonus (2), it is further determined whether or not the total number of medals paid out exceeds 400 (step S307). If the total number of medals paid out does not exceed 400, the process proceeds to step S310. If the total number of medals paid out exceeds 400, the big bonus (2) ends here, and the process proceeds to step S308.

  In step S308, the big bonus (1) medium flag or big bonus (2) medium flag set in the RAM 112 is erased, and a counter value for counting the total number of medals paid out is initialized to 0 (step S308). S308). Since the big bonus (1) or the big bonus (2) ends here, the maximum RT game number 500 is set in the RT counter of the RAM 112 (step S309), and the process of step S312 is performed. Proceed to

  In step S310, the counter provided in the RAM 112 is used to calculate the number of digested games and the number of winning games since the regular bonus for the current set provided with the big bonus (1) or the big bonus (2) is started. Count. As a result of this counting, it is determined whether the number of winning games in the regular bonus has become 6 or the number of digest games in the regular bonus has become 12 (step S311).

  If the number of winning games in the regular bonus has become 6 or the number of digested games in the regular bonus has become 12, the process proceeds to step S312. If the number of winning games in the regular bonus is not six and the number of digest games in the regular bonus is not twelve, the process proceeds to step S315. In step S312, the regular bonus flag set in the RAM 112 is erased, and the counter values for counting the number of digest games and the number of winning games in the regular bonus are both initialized to zero. Then, the process proceeds to step S315.

  If the game state of the game is neither the big bonus (1) nor the big bonus (2) in step S303, it is determined whether or not the value of the RT counter in the RAM 112 is 0 (step S313). If the RT counter value is not 0, the RT counter value is decremented by 1 (step S314), and the process proceeds to step S315. If the value of the RT counter is 0, the process proceeds to step S315 as it is.

  In step S315, if the watermelon winning flag, the bell winning flag, the cherry winning flag, the special A winning flag, the special B winning flag, the special C winning flag, and the replay winning flag are set in the RAM 112, these are deleted. The big bonus (A) winning flag, the big bonus (B) winning flag, and the big bonus (C) winning flag are not erased here and are carried over to the next game. If a winning flag is set in the RAM 112 in step S203, it is deleted.

  Next, based on the big bonus (1) medium flag and the big bonus (2) medium flag in the RAM 112 and the value of the RT counter, a game state command indicating a game state applied in the next game is generated, It transmits to the control board 102 (step S316). Then, the payout process is terminated, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 5, the process in the current one game ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 further increases the big bonus (1) or big bonus (2) between the normal gaming state, RT, big bonus (1) and big bonus (2). ), The game state is repeatedly transferred to the regular bonus, and a command is transmitted to the effect control board 102 in accordance with the progress of the game. On the other hand, the CPU 121 of the effect control board 102 selects an effect in the big bonus (1) or the big bonus (2) based on a command received from the game control board 101, and an effect including game navigation in RT. Is being processed. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  9 to 11 are flowcharts showing processing executed by the CPU 121 of the effect control board 102. On the side of the effect control board 102, it is determined whether or not a command sent from the game control board 101 has been received (step S401). When any command is received from the game control board 101, it is determined what kind of the received command is (step S402).

  If the received command type is the BET command transmitted in step S2, the game state to be started from now is referred to with reference to the two game states stored in the RAM 122 in step S458 (described later) of the previous game. It is determined whether the first game after the end of the big bonus (1) or the big bonus (2) is reached (step S403). If it is the first game after the end of the big bonus (1) or the big bonus (2), it is determined whether or not the value of the navigation counter in the RAM 122 is 0 (step S404). If the value of the navigation counter is 0, the process directly returns to step S401.

  If the value of the navigation counter is not 0, it means that the player has been given the right of game navigation in the big bonus (1) or big bonus (2) that ended in the previous game. In this case, the switching display of the characters 1 and 2 started in step S465 (described later) and performed on the liquid crystal display 4 is stopped (step S405). Then, it is determined whether the type of the stopped character is character 1 (step S406). If it is not character 1, it returns to the process of step S401 as it is. If it is character 1, since the player has selected to try to double up the number of times of game navigation, a double up selection flag is set in RAM 122 (step S407). Then, the process returns to step S401.

  If the game to be started is not the first game after the end of the big bonus (1) or the big bonus (2), refer to the two game states stored in the RAM 122 in step S458 (described later) of the previous game. Then, it is determined whether or not the game to be started is a big bonus (1) or big bonus (2) start game (step S408). If it is a start game of the big bonus (1) or the big bonus (2), the switching display of the characters A, B, C started in step S460 (described later) and performed on the liquid crystal display 4 is stopped ( Step S409). Then, information indicating the type of the stopped character is stored in the RAM 122 (step S410). Then, the process returns to step S401.

  If the game to be started is not the big bonus (1) or big bonus (2) start game, it is determined whether or not the B lottery is selected by the selection of the character B and whether or not the B notification flag is set in the RAM 122 ( Step S411). If the B notification flag is set, it is determined whether or not the watermelon or cherry has been won in the previous game with reference to the winning information stored in the RAM 122 in step S447 (described later) of the previous game (step S412). .

  If a watermelon or cherry tree has been won in the previous game, a navigation notice is given on the liquid crystal display 4 with an effect by the character B to notify the player that the right of game navigation has been granted (step S413). . Then, the process proceeds to step S414. If neither watermelon nor cherry is won in the previous game, the game navigation right is granted to the player, but this is not known from the display result of the variable display device 2, so the navigation notification is performed. Without proceeding to step S414.

  In step S414, the B notification flag set in the RAM 122 is erased and the player is given the right to perform game navigation after the end of the big bonus (1) or the big bonus (2). The initial value of the remaining number of game navigations when the double-up lottery is not passed is set to 5 in the navigation counter of the RAM 122. Then, the process returns to step S401. If the B notification flag is not set in step S411, the process directly returns to step S401.

  If the received command type is the winning status notification command transmitted in step S117, the game state of this time is referred to with reference to the game state stored twice in the RAM 122 in step S458 (described later) of the previous game. It is determined whether or not the gaming state at is RT (step S415). If the gaming state in the current game is RT, it is determined whether or not the value of the navigation counter in the RAM 122 is greater than 0 (step S416). If the value of the navigation counter is 0, since the player does not have the right of game navigation, the process directly returns to step S401.

  If the value of the navigation counter is greater than 0, refer to the winning status indicated by the received winning status notification command, and whether or not the bell, cherry, special A, special B or special C was won in this game Is determined (step S417). If none of the bell, cherry, special A, special B, and special C is won in this game, it is determined whether or not all the combinations have been lost in this game (step S418). If all the roles are lost in the current game, the process of step S430 is performed. If any role other than the bell, cherry, special A, special B, or special C is won in the current game, the process of step S431 is performed. Proceed to

  If any of the bell, cherry, special A, special B, or special C is won in this game, it is determined whether or not the double up selection flag is set in the RAM 122 (step S419). If the double-up selection flag is selected, the player has chosen to try to double-up the number of times of game navigating. Therefore, whether the cherry or special A is won, the bell or special B is won The background color of the liquid crystal display 4 is displayed with a red, yellow, and black stripe pattern so that it is not known whether it is selected or the special C is won (step S420). Then, the double-up selection flag is deleted, and the double-up notification flag is set in the RAM 122 (step S421). Thereafter, the process proceeds to step S431.

  If the double-up selection flag is not set, it is determined whether or not the winning in the current game is cherry or special A (step S422). If it is cherry or special A that is won in this game, the background color of the liquid crystal display 4 is displayed in red so that it can be seen that the cherry or special A is won (step S423). ). Here, since the game navigation is performed once, the value of the navigation counter in the RAM 122 is decremented by 1 (step S424). Then, the process proceeds to step S431.

  If it is neither cherry nor special A that is won in this game, it is determined whether or not it is Bell or Special B that was won in this game (step S425). If it is the bell or special B that is won in this game, the background color of the liquid crystal display 4 is displayed in yellow so that it can be seen that the bell or special B is won (step S426). ). Here, since the game navigation is performed once, the value of the navigation counter in the RAM 122 is decremented by 1 (step S427). Then, the process proceeds to step S431.

  If the winner of this game is neither Bell nor Special B, the winner of this game is Special C. The color is displayed in black (step S428). Here, since the game navigation is performed once, the value of the navigation counter in the RAM 122 is decremented by 1 (step S429). Then, the process proceeds to step S431.

  In step S430, since all the combinations are lost in this game, the winning probability is 1/32 and the navigation addition lottery is performed. In step S431, since a winning combination is won in this game, a navigation addition lottery is performed with a winning probability of 1/16384. After the navigation addition lottery is performed in step S430 or S431, it is determined whether or not it is determined to add the number of game navigations (step S432). If it is determined to add the number of game navigations, the value of the navigation counter in the RAM 122 is incremented by 1 (step S433), and the process returns to step S401. If it is determined not to add the number of game navigations, the process directly returns to step S401.

  If the gaming state in the current game is not RT in step S415, the value of the navigation counter in the RAM 122 is cleared to 0 (step S434). Further, it is determined whether the game state in the current game is the big bonus (1) or the big bonus (2) by referring to the two game states stored in the RAM 122 in step S458 (described later) of the previous game. (Step S435).

  If the game state of the current game is neither the big bonus (1) nor the big bonus (2), the process directly returns to step S401. If the game state in the current game is a big bonus (1) or a big bonus (2), it corresponds to the character type stored in step S410 and the progress of the big bonus (1) or big bonus (2). An image is displayed on the liquid crystal display 4 and an effect during the big bonus is performed (step S436).

  Next, it is determined whether or not the character type stored in step S410 is character A and the received winning status notification command indicates that special A + special B + special C is won in the current game. (Step S437). When the character type is character A and special A + special B + special C is won, navigation lottery is performed by random lottery with a win probability of 1/32 (step S438), and as a result, game navigation is sent to the player. It is determined whether or not it is determined to grant the right (step S439). If it is determined that the game navigation right is to be given to the player, an A notification flag is set in the RAM 122 (step S440), and the process returns to step S401. If it is determined not to grant the game navigation right to the player, the process directly returns to step S401.

  If the character type is not character A or the winning status notification command does not indicate that special A + special B + special C is won, the character type stored in step S410 is character B. In addition, it is determined whether or not the received winning status notification command indicates that watermelon or cherry is won in the current game (step S441).

  If the character type is character B and a watermelon or cherry is won, a random lottery with a winning probability of 1/4 is performed (step S442), and as a result, the player has the right of game navigation. It is determined whether or not it has been determined to give (step S443). If it is determined that the game navigation right is to be given to the player, the B notification flag is set in the RAM 122 (step S444), and the process returns to step S401. If it is determined not to grant the game navigation right to the player, the process directly returns to step S401.

  If the character type is not character B, or if the winning status notification command does not indicate that watermelon or cherry is won, the character type stored in step S410 is character C, and It is determined whether or not the received winning status notification command indicates that the current game has won the bell (step S445).

  If the character type is character C and the bell is won, 5 is set as the initial value of the remaining number of game navigations when the double-up lottery is not passed in the navigation counter of the RAM 122 (step S446). . If the character C is selected and the bell is won, the game navigation right is granted to the player with a probability of 100%. This is substantially the same as the fact that the lottery with a winning probability of 100% is won. The same thing. Then, the process returns to step S401. If the character type is not character C, or if the winning status notification command does not indicate that the bell is won, the process directly returns to step S401.

  If the received command type is the winning information command transmitted in step S216, the winning information indicated by the received winning information command is stored in a predetermined area of the RAM 122 (step S447). Next, it is determined whether or not the game state in the current game is RT with reference to the game state for two times stored in the RAM 122 in step S458 (described later) of the previous game (step S448). If the gaming state in the current game is RT, it is determined whether or not a double-up notification flag is set in the RAM 122 (step S449). If the double-up notification flag is not set, the process directly returns to step S401.

  If the double-up notification flag is set, it is determined whether or not the stored winning information indicates that a special A, special B or special C has been won in the current game (step S450). If it indicates that a special A, special B, or special C has been won, the value of the navigation counter in the RAM 122 is doubled (step S451), and the process proceeds to step S453. If no special A, special B, or special C win is indicated, the value of the navigation counter in the RAM 122 is cleared to 0 (step S452), and the process proceeds to step S453. In step S453, the double-up notification flag set in the RAM 122 is deleted. Then, the process returns to step S401.

  If the game state in the current game is not RT, whether or not the game state in the current game is a big bonus by referring to the two game states stored in the RAM 122 in step S458 (described later) of the previous game. Is determined (step S454). If the gaming state in the current game is a big bonus, it is determined whether or not 5 is already set in the navigation counter of the RAM 122 (step S455). If 5 is already set in the navigation counter, the process directly returns to step S401.

  If 5 is not set in the navigation counter, it is determined whether or not the character type stored in step S410 is character C and the received winning information command indicates a winning of a bell (step S456). If the player has won the bell, the liquid crystal display 4 performs navigation notification with the effect by the character C to notify the player that the right of game navigation has been granted (step S457). Then, the process returns to step S401.

  In step S454, if the game state in the current game is neither big bonus (1) nor big bonus (2), if the navigation counter is already set to 5 in step S455, or the character type is character in step S456. If it is not C or does not indicate that the player has won the bell, the process directly returns to step S401.

  If the received command type is the gaming state command transmitted in step S316, the gaming state stored in the gaming state storage area for two games in the RAM 122 is shifted (received in the previous game). The gaming state indicated by the gaming state command is evicted), and the gaming state indicated by the gaming state command received in the current game is stored (step S458).

  Next, with reference to the game state for two times stored in the RAM 122, it is determined whether the big bonus (1) or the big bonus (2) starts from the next game (step S459). If the big bonus (1) or the big bonus (2) starts from the next game, the character switching display for switching the characters A, B, and C on the liquid crystal display 4 for a certain period is started ( Step S460). Then, the process returns to step S401.

  If the big bonus (1) or the big bonus (2) does not start from the next game, the game state for two times stored in the RAM 122 is further referred to and the big bonus (1) or big bonus ( It is determined whether or not (2) is finished (step S461). If the big bonus (1) or the big bonus (2) is not ended in the current game, the process directly returns to step S401.

  If the big bonus (1) or big bonus (2) ends in the current game, the selection of the character A wins the navigation lottery and determines whether or not the A notification flag is set in the RAM 122 (step S1). S462). If the A notification flag is set, the liquid crystal display 4 performs navigation notification with the effect by the character A to notify the player that the right of game navigation has been granted (step S463). Further, 5 which is the initial value of the remaining number of game navigations when the double-up lottery has not passed is set in the navigation counter of the RAM 122, and the A notification flag is deleted (step S464). Then, the process proceeds to step S465.

  If the A notification flag is not set in the RAM 122, the process directly proceeds to step S465. In step S465, the character switching display for switching the characters 1 and 2 to be displayed on the liquid crystal display 4 for a certain period is started. Then, the process returns to step S401.

  If the received command type is another command, processing corresponding to each command type is executed (step S466). Since the processing here is not related to the present invention, detailed description thereof is omitted. Thereafter, the process returns to step S401.

  As described above, in the slot machine 1 according to this embodiment, after the big bonus (1) or the big bonus (2) is finished, the gaming state is controlled to RT that continues for up to 500 games. RT is a game state that is advantageous to a player who has won a replay more than the normal game state, but in addition to winning a big bonus (A), big bonus (B), or big bonus (C), Even when the cherry tree is won, the game is ended even before 500 games are consumed.

  When the gaming state is RT, if the right of the navigation is selected in the big bonus (1) or the big bonus (2) immediately before that and the right of the game navigation is granted to the player, the number of games of the right is exhausted. Until the game is completed, a game navigation is performed when a bell, cherry, special A, special B or special C is won. The game navigator displays red on the background of the image displayed on the liquid crystal display 4 when the cherry or special A is elected, yellow on the background of the bell or special B, and black on the background when the special C is elected. This is done.

  Here, when the background is displayed in red, the special A and cherry may have been won, but at least the left reel 3L displays “red 7” which constitutes the display mode of the special A If the stop button 12L is operated at the same timing, “cherry” is not derived to the left reel 3L regardless of the winning combination. In addition, special B and bell may be selected when the background is displayed in yellow, but at least the left reel 3L is displayed with “yellow 7” which constitutes the display mode of special B If the stop button 12L is operated at a certain timing, the “bell” is derived to the left reel 3L regardless of the winning combination, and the bell is not won.

  In this way, even if the background color of the image displayed on the liquid crystal display 4 in RT changes, the operation procedure of the stop buttons 12L, 12C, and 12R for obtaining the winning combination is not uniquely determined. The person still has to select the order in which the stop buttons 12L, 12C, and 12R are operated, and at what timing. Thereby, the game in the game in which the winning of the cherry or special A and the winning of the bell or special B is notified in RT does not become monotonous, and the interest of the game can be improved.

  In addition, in Cherry and Special A, which are notified of the winning of the red background, the number of medals to be paid out for the special A is greater. In the bell and special B in which the winning is notified with a yellow background, the number of medals to be paid out by winning the special B is larger. For this reason, even if the winning procedure is notified by the change in the background color of the image displayed on the liquid crystal display 4 and the operation procedure for winning the winning combination is not uniquely determined, the player stops The operation procedure of the buttons 12L, 12C, and 12R can be selected as an operation procedure that seems to be the best strategy.

  Furthermore, among the cherry and special A that are notified of the winning of the red background, the RT is not terminated by winning the special A, but the RT is terminated by winning the cherry. Among the bells and special Bs that are notified of winning with a yellow background, RT is not terminated by winning the special B, but RT is terminated by winning the bell. For this reason, even from this viewpoint, even if the winning is notified by the change in the background color of the image displayed on the liquid crystal display 4, and the operating procedure for winning the winning combination is not uniquely determined, The player can select an operation procedure that seems to be a strategy for operating the stop buttons 12L, 12C, and 12R.

  Further, the maximum number of continuous RT games controlled after the end of the big bonus (1) or the big bonus (2) is 500 games. On the other hand, the probability of winning the big bonus (A), big bonus (B), or big bonus (C) in the normal gaming state or RT is approximately 1 / 149.6. That is, the expected value of the number of games between bonuses is larger than the maximum number of continuous games of RT. For this reason, the big bonus (A), the big bonus (B), or the big bonus (C) is often won while the gaming state is controlled to RT. As a result, there may be a case where the game is played for a long period of time in a gaming state advantageous to the player, that is, the big bonus (1) or the big bonus (2) and RT, so that the player's expectation is enhanced and the game is enhanced. Can be improved.

  By the way, whether or not the RT or the special B wins or the special C win or not grants the player the right of game navigation to be notified by the change of the background image. It is determined when the big bonus (1) or the big bonus (2) before the start is controlled.

  Here, before the first game of the big bonus (1) or the big bonus (2) is started, the characters A to C are sequentially switched and displayed on the liquid crystal display 4 to set the player's bet amount. When the number of bets for the first game of big bonus (1) or big bonus (2) is determined by the operation, the type of character displayed at that time is called the type of character applied to the big bonus medium performance. It will be. As described above, since the contents of the effect during the big bonus change depending on the selection of the character type according to the setting timing of the bet number, the fun of selecting the character type is increased.

  When the big bonus (1) or the big bonus (2) controls whether or not to give the player the right of game navigation in RT after the end of the big bonus (1) or the big bonus (2) Depending on the type of the selected character, the character A is selected when the character A is selected, the special A to C are won, the watermelon or cherry is won when the character B is selected, the bell is won when the character C is selected. Is different. In addition, the probability that navigation is performed at each opportunity is also different from 1/32, 1/4, and 1/1.

  However, considering the winning probabilities of each combination, the probability that it will be determined that the right of game navigation will be granted by the end of the big bonus (1) or big bonus (2) is selected from any type of character. But there is no big difference. Thus, the selection of the character at the start of the big bonus (1) or the big bonus (2) affects not only the presentation but also the progress of the game itself. The interest of the game can be improved.

  Further, when it is determined that the right of game navigation is to be granted in the big bonus (1) or the big bonus (2), a navigation notification is made to notify the player of this. The images displayed on the screen are images of the selected characters. Further, the timing of the navigation notification is also made when the big bonus (1) or the big bonus (2) ends when the character A is selected, and when the bet number for the next game is determined when the character B is selected. When the character C is selected, there is a difference depending on the type of the selected character immediately upon winning the bell. As described above, the selection of the character at the start of the big bonus (1) or the big bonus (2) also makes a difference in the navigation notification method performed when it is determined that the right of game navigation is given. The fun of selecting the character type can be further increased.

  Further, when the gaming state is controlled to RT and the right of the game navigation that has been granted has not yet been digested, it is determined whether or not to increase the number of times that the game navigation is performed. In other words, the navigation lottery is performed in each game when controlled by RT, and the number of times that game navigation is performed is added by winning the game. Of course, the navigation lottery in this case has a low winning probability when a certain role is won, but wins with a relatively high winning probability when all the roles are lost. For this reason, even if the player cannot win any role in the RT game, this increases the expectation that the number of game navigations will be added, and thus the player's expectation will not be reduced.

  Further, before the game immediately after the big bonus (1) or the big bonus (2) is finished, the characters 1 and 2 are sequentially switched and displayed on the liquid crystal display 4 to set the player's bet amount. When the number of bets for the game immediately after the big bonus (1) or the big bonus (2) is ended by the operation is determined, if the character (1) is displayed at that time, the number of game navigations is doubled up. It will be chosen to try.

  If it is chosen to try to double up the number of game navigating times, the bell, cherry, special A, special B or special C will be used first at RT after the end of the big bonus (1) or big bonus (2). In the winning game, the display image on the liquid crystal display 4 is changed to a red, yellow and black stripe pattern. In this case, the player does not know which of the bell, cherry, special A, special B, or special C is won, but if he can make a special A, special B or special C prize, The number of game navigators will be doubled (if the bell or cherry is won, RT will end in any case).

  For example, when the double-up is not tried in a state where the number of game navigations is not added, the number of game navigations performed is only 5. RT can last for 500 games at the maximum, but if you consider the winning probability of Bell, Cherry, Special A, Special B or Special C, you will actually digest about 10% of them. Game navigation can no longer be performed, and RT will end soon.

  On the other hand, if the double-up try is successful, the game navigation is performed 10 times, so the game navigation is performed until about 20% of the RT that continues for 500 games at the maximum is consumed. As a result, the continuation of RT can be extended. For this reason, it is possible to increase the possibility of increasing the number of continuous games by the player's selection of trying to double up, and to further improve the interest of the game.

  Furthermore, the expected value of the number of continuing games for RT that takes into account that it will end due to the winning of a bell or a cherry is based on the assumption that the player can stop operation according to all the lower level game navigators. When the double-up is successful, the expected number of games is close to the inverse of the probability of winning the big bonus (A), big bonus (B), or big bonus (C). This increases the player's expectation because the possibility of playing a game for a long period of time with the big bonus (1) or big bonus (2) and RT being advantageous to the player is very high. The interest of the game can be improved.

  However, if the double-up try fails, for example, if you actually win the bell but operate the stop button 12L at the timing to win a special A while avoiding cherries, you will win. There is a greater risk that the RT will be ended after winning the bell. In this way, when trying to double up, not only will you lose the right of game navigator, but you will also have the risk that if you win a bell or cherry, RT will also be terminated, so in a game when trying to double up The excitement of the player will increase, and the interest of the game can be further improved.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, although any of the characters A, B, and C is selected by the player at the start of the big bonus (1) or the big bonus (2), there is a difference in timing. The notification of granting the right of navigation is all performed by displaying an image on the liquid crystal display 4. But it is good also as what alert | reports grant of a navigation right in the aspect different from the display of the image on the liquid crystal display 4 in part or all of three types of characters. For example, when sound is output from the speakers 7L, 7R, and 7U, predetermined sound may be output according to the type of the selected character.

  In the above embodiment, before the first game of the big bonus (1) or the big bonus (2) is started, the characters A to C are sequentially switched and displayed on the liquid crystal display 4, and the big bonus (1) or The type of effect in the big bonus (1) or the big bonus (2) is selected according to the type of the character displayed at the timing when the number of bets for the first game of the big bonus (2) is fixed I was trying.

  However, the type of performance in the big bonus (1) or the big bonus (2) is not selected by an operation related to the progress of the game as in the setting of the bet number, but the game is performed by an operation completely independent of the progress of the game. The user may be able to select. Further, the effect that the contents are changed in the big bonus (1) or the big bonus (2) according to the player's selection may be only the notification of granting the right of navigation.

  In the above embodiment, whether or not to give the player the right of the game navigation at a different opportunity according to the type of character selected by the player at the start of the big bonus (1) or the big bonus (2). Was to be determined. Then, when it is determined that the right of game navigation is to be granted, navigation is performed in a different manner depending on the type of character selected by the player at the start of the big bonus (1) or the big bonus (2), and at different timings. The announcement was to be made. On the other hand, only the mode of notification of granting the right of navigation differs depending on the type of character selected by the player, or the type of character selected by the player only at the timing of notification of granting of the right of navigation It can be different depending on the situation.

  In the above embodiment, the characters 1 and 2 are sequentially switched and displayed on the liquid crystal display 4 before the first game immediately after the end of the big bonus (1) or the big bonus (2) is started. When character 1 is displayed at the timing when the number of bets for the first game immediately after the end of 1) or big bonus (2) is confirmed, it is now possible to try to double up the number of times of game navigation .

  However, whether or not to try to double up the number of times of game navigation is selected by the player by an operation completely independent of the progress of the game, not by the operation related to the progress of the game as in the setting of the number of bets You may be able to do it. Also, the player decides whether to try to double up the number of game navigations by lottery instead of selecting whether to try to double up the number of game navigations by his own game operation It is good. Furthermore, it is not necessary to try to double up the number of game navigations.

  In the above embodiment, the gaming state is controlled to RT after the end of the big bonus (1) or the big bonus (2), and the game navigation right is given during the big bonus (1) or the big bonus (2) in the RT. The player is notified of the Cherry or Special A win, the Bell or Special B win, or the Special C win, provided that the player has been granted (and has not lost his rights in the double-up try). It was a thing. However, even if the gaming state is not controlled to RT after the end of the big bonus (1) or the big bonus (2), the cherry or special A win, the bell or special B win, Or it is good also as what notifies the winning of special C winning.

  In the above embodiment, when the navigation lottery is won in the big bonus (1) or the big bonus (2), the right of game navigation for five games is notified to the player in the subsequent RT. The number of games for which game navigation is performed is added by winning the navigation addition lottery performed in each game of RT, and the player selects the bell, cherry, special A, special B, or special C first at RT. It was to be doubled by succeeding in the double-up trial performed when winning. The right of game navigation is deducted by one game every time the player is notified of the winning of cherry or special A, the winning of bell or special B, or the special C.

  On the other hand, when winning the navigation lottery in Big Bonus (1) or Big Bonus (2), the right of Game Navi is that of Cherry or Special A, Bell or Special B, or Special C Regardless of the presence or absence of notification, it will be subtracted every time one game is consumed, and as long as the right of game navigation remains in RT, what if you win the bell, cherry, special A, special B or special C? The player may be notified of the winning of cherry or special A, the winning of bell or special B, or the special C.

  For example, when the navigation lottery is won in the big bonus (1) or the big bonus (2), 40 games are given to the player as the right of game navigation. The number of games in this game navigation can be incremented by 5 by winning the navigation addition lottery, and can be doubled by successful double-up trial. When one game is consumed in RT, the number of remaining games in the game navigation right is decremented by one, regardless of whether the winning of Cherry or Special A, the winning of Bell or Special B, or the special C is notified. Can be.

  In this case, when the right of game navigation is granted to the player, until the number of games of the right of game navigation (including the case of addition or doubling) is consumed, bell, cherry, special A, special B Or, if you win a special C, you will be notified of the winning of cherry or special A, the winning of bell or special B, or the special C, so the player can press the stop button 12L appropriately according to the notification. As long as it can be operated, it is possible to continue RT exactly as many times as the number of games granted as the right of game navigation.

  In the above embodiment, in the game navigation that is performed when the bell, cherry, special A, special B, or special C is won at RT, the red background image indicates that the cherry or special A is won. The winner of the bell or special B is notified by the background image, and the special C winner is notified by the black background image. Here, in the game navigation in which the background image is changed to black, the player knows only that the special C is won.

  So, for example, when you win the bell, you can draw whether you don't know which of the special B and the bell is won, or the special C or the bell. When it is decided not to know which of special B and bell is won by the lottery, the background image is changed to yellow, and either special C or bell is won by the lottery. If it is decided not to know, the background image may be changed to a yellow and black striped pattern.

  In the above embodiment, when some of the three reels 3L, 3C, 3R are already stopped, the internal winning state for each gaming state and the stop position of the stopped reel are unique. A stop control table that is determined in a specific manner is selected, and reel stop control is performed in accordance with the selected stop control table. Here, instead of the stop position of the stopped reel, the position when the stop buttons 12L, 12C, and 12R are operated to stop the reel (that is, the number of steps of the reel) may be applied. Good. Also in this case, similarly to the selection of the stop control table in the above embodiment, it is possible to obtain an effect that the control for stopping the reel does not become complicated.

  In the above embodiment, the number of determination values for the lottery target determined according to the gaming state is sequentially added to the random number for internal lottery, and is read as the lottery target at the time when an overflow occurs as a result of the addition. He was supposed to win the role that had been put out. On the other hand, the number of determination values may be sequentially subtracted from the internal lottery random value, and the result of the subtraction may be used as a new internal lottery random value. When the number of determination values is subtracted from the random number value for internal lottery, it can be determined whether or not an overflow has occurred in the subtraction result (here, the subtraction result becomes negative). In addition, according to the number of determination values of each combination according to the gaming state, a winning determination table that determines a determination value for determining each combination as winning is created for each game, and the acquired random number for internal lottery is set. It is good also as what performs an internal lottery by comparing with the determination value of each combination.

  In the above embodiment, in any gaming state, the game can be started only by setting 3 as the bet number. However, the number of bets that can be set to start the game can be any number in the range of 1 to 3. The number of bets that can be set for each gaming state may be different. Here, when 1 or 2 is set as the bet number in the normal gaming state or RT, the winning probability of the small part in the internal lottery is lowered and the small part is reduced as compared with the case where 3 is set as the bet number. It is possible to increase the number of medals to be paid out when winning.

  In the above embodiment, in a game where the gaming state is the big bonus (1) or the big bonus (2) and the big bonus (1) flag or the big bonus (2) flag is set in the RAM 112, the start lever It is determined whether or not the regular bonus flag is set in the RAM 112 during the operation of No. 11. If the regular bonus flag is not set, this is set to control the regular bonus. In this way, even when the regular bonus is controlled for the first time after winning the big bonus (A), big bonus (B), or big bonus (C), the regular bonus is completed and the big bonus (1) or big bonus ( Even when the regular bonus is controlled again when 2) is not completed, the same process should be performed.

  On the other hand, when the big bonus (A), big bonus (B), or big bonus (C) is won, the regular bonus flag is displayed in the RAM 112 together with the big bonus (1) flag or the big bonus (2) flag. When the regular bonus end condition is established in the big bonus (1) or the big bonus (2), the regular bonus medium flag is deleted. Here, when the regular bonus medium flag is deleted, it is determined that the end condition of the big bonus (1) or the big bonus (2) is not satisfied, and the big bonus (1) medium flag or the big bonus (2) is determined. If the medium flag is set in the RAM 112, the regular bonus medium flag may be set in the RAM 112 again and controlled to a new regular bonus as it is.

  In this case, the gaming state is controlled to the big bonus (1) or the big bonus (2) by winning the big bonus (A), the big bonus (B) or the big bonus (C), and at the same time, the regular bonus is controlled. In addition, when the regular bonus for one time is finished and the big bonus (1) or the big bonus (2) is not finished yet, it is possible to immediately return to the regular bonus.

  Further, when controlled to the big bonus (1) or the big bonus (2), first, a small role game is provided, and further, based on JACIN winning in the small role game, JACIN (for example, “JAC-Bell-Bell”). It is also possible to provide a regular bonus in the big bonus (1) or the big bonus (2) by winning a prize in an internal lottery during a small role game. If the regular bonus for one set is ended during the big bonus (1) or the big bonus (2) and the number of payout medals has not yet exceeded 400, it can be controlled again as a small role game.

  In the above embodiment, the stop control table is selected in advance based on the setting status of the winning flag, the stop position of the symbol is determined with reference to the stop control table when the reels 3L, 3C, 3R are stopped, and the stop The slot machine that stops the rotation of the reels 3L, 3C, and 3R by the table system that stops the reel at the position has been described as an example. In contrast, based on the current symbol position when the stop condition is satisfied and the setting status of the winning flag, pull-in control is performed so that the symbol of the winning symbol is aligned, or the symbol of the symbol that is not winning The present invention can also be applied to a slot machine that stops the rotation of the reels 3L, 3C, and 3R by a control method in which the removal control is performed so as not to align.

  In the control method, when the operation of the stop buttons 12L, 12C, 12R is detected, the corresponding reels 3L, 3C, 3R are within the range of the maximum stop delay time of 190 milliseconds from the symbol displayed at that time ( It is determined whether or not there is a winning symbol having a winning flag set in a range of a total of five frames including the displayed symbol and the amount drawn.

  If there is a symbol with a winning flag set (determined from the symbol of the role that is given priority for derivation in duplicate wins), select the symbol for winning the winning combination and select the winning line (already stopped) When there is a reel, the winning display mode can be derived along with the symbols on the stopped reel. Otherwise, a symbol for not winning any combination is selected and derived. That is, even when the stop of the reels 3L, 3C, 3R is controlled by this control method, it can be derived by stopping the symbols within the range of the maximum stop delay time after the operation of the stop buttons 12L, 12C, 12R is detected. The display mode corresponding to the setting status of the winning flag is derived as the display result of the variable display device 2.

  In the above embodiment, the variable display device 2 includes the three reels 3L, 3C, and 3R in which a plurality of symbols are arranged in a predetermined order on the outer periphery, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, a device that virtually displays a symbol on a display device such as a liquid crystal display device may be used instead of the variable display device 2 described above.

  In the above-described embodiment, the slot machine to which medals are applied as a game medium used for setting the number of bets and giving game value associated with winning is described as an example. However, the slot machine embodying the present invention may be a slot machine (so-called parrot) to which a game ball used in a pachinko gaming machine is applied as a game medium. When a game ball is used as a game medium, for example, one medal can correspond to five game balls.
