Description

  The present invention relates to a slot machine, and more particularly to an effect performed in a special game state that is more advantageous to the player than the normal game state.

  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.

  When a symbol of bonus combination such as a regular bonus or a big bonus is derived in the winning display mode, the game state is controlled to a bonus game state that is more advantageous to the player than the normal game state. By controlling the game state different from the normal game state such as this bonus, the game is sharpened and the interest of the game is improved. In addition to the normal gaming state and the bonus gaming state, for example, there is an RT that increases the probability of winning a replay in the internal lottery compared to the normal gaming state, and further enhances the interest of the game. .

  As described above, the change in the game state in the slot machine has a great influence on the progress of the game, and therefore, in many slot machines, different effects are provided for each game state. In addition, even if the gaming state is not currently controlled, if it is internally determined that the gaming state is controlled (for example, if a bonus combination is won in an internal lottery) The game interest can be improved by notifying the information that shows the player's interest in the internal decision and what kind of decision has been made.

  Here, the effect in the slot machine is merely an effect and is not directly related to the progress of the game, but if the effect is too simple, the game will be boring. Thus, there has been a slot machine that allows a player to select a mode of performance to be executed (see, for example, Patent Document 1). Also, in the pachinko gaming machine having a change in the gaming state as a basic gaming property like the slot machine, there is one that changes the mode of effect during the jackpot depending on the gaming state controlled after the jackpot ( For example, see Patent Document 2).

  However, in the slot machine disclosed in Patent Document 1, the player selects an aspect of performance that is not directly related to the progress of the game, and the progress of the game itself changes depending on the player's selection. It never happened. Further, even in the slot machine of Patent Document 2, simply changing the aspect of the effect according to the gaming state that has been determined to be controlled after the big hit, the new aspect is changed. There was no effect on the change of the game state.

  An object of the present invention is to provide a slot machine that can enhance the interest of a game by making the change in the type of production interesting and enhancing the player's sense of intervention in the game.

To achieve the above object, a slot machine according to the present invention includes:

When the special game state is controlled, lotteries with different winning conditions are performed according to the types of effects selected by the effect selecting means, and the conditions (selection of character A selected in advance) are determined according to the results of the lottery. When the character B is selected, the condition is determined by means of determining whether or not the character B is selected and the watermelon or cherry is selected, and when the character C is selected, the winning of the bell 2 to the bell 4 is determined (step S912). S916, S940),
When it is determined by the condition establishment determination means that the condition is established, the gaming state is controlled to a specific gaming state (RT navigation) advantageous to a player different from the special gaming state after the special gaming state is ended. Specific game state determination means (steps S913, S917, S940 (YES)) for determining whether or not
Specific game state notifying means (steps S941, S950, S962) for notifying the player that the specific game state is to be controlled when it is determined by the specific game state determining means that the control is to be performed in the specific game state; ,
Specific game state control means (steps S942, S951) for controlling the game state to the specific game state after the special game state is ended when the specific game state determination means determines to control to the specific game state. , S963)
The specific gaming state notifying means is in a mode according to the type of the effect selected by the effect selecting means (when selecting the character A, the RT navigation notification is made with the image of the character A at the end of the big bonus, and when the character B is selected. The fact that the game state is controlled to the specific gaming state is notified when the next game is betted with the image of the character B, and immediately when the character C is selected (the character C image).

  In the above-mentioned slot machine, the type of effect executed in the special game state can be selected by the player by his / her own operation, so that the interest of the effect executed in the special game state is improved and the type of effect is selected. Will be more interesting.

  Further, when the special gaming state is controlled, it is determined whether or not the gaming state is controlled to the specific gaming state after the special gaming state is ended. When the determination is made, the specific gaming is performed after the special gaming state is ended. The gaming state is controlled by the state. Here, when it is determined to be controlled to the specific gaming state, the fact is notified to the player by the specific gaming state notification means, and the notification mode is also an effect that the player has selected by his own operation. Since it differs depending on the type of the item, the interest in selecting the type of production is further increased.

  Furthermore, whether or not to control to the specific game state in the special game state is determined when a condition determined according to the type of the effect that the player has selected by his / her own operation is established, Interesting to the selection will be further increased. In addition, since the selection of the type of production in the special game state by the player affects not only the production and information notification but also the progress of the game itself, that is, the control to the specific game state. Can increase the sense of intervention and improve the interest of the game.

  Note that the type of effect selected by the effect selection means is, for example, the type of image displayed when an effect is displayed by displaying an image in the special gaming state, or a voice in the special gaming state. In the case where an effect by the output is performed, it can mean the type of sound to be output.

The slot machine is
Before the display result of the variable display device is derived for each game, it is determined whether or not the winning display result is allowed to be derived, and the determination result information (winning flag) corresponding to the result of the determination is set. Pre-decision means (step S403);
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 S404) for causing the variable display device to derive a display result in accordance with the determination result information set by the prior determination means and the operation procedure of the stop operation means;
When a predetermined advantageous display result (Bell 2 to Bell 4) is derived as the display result of the variable display device, the game is brought into an advantageous state (RT2) advantageous to a player that is different from the special gaming state and the specific gaming state. Advantageous state control means (step S715) for controlling the state may be further provided. In this case,
The derivation control means is any one of a plurality of types of advantageous decision result information (bell 1 + bell 2, bell 1 + bell 3, bell 1 + bell 4) in which the decision result information set by the prior decision means is predetermined. If there are a plurality of types of operation procedures determined in accordance with the type of the advantage determination result information (FIG. 2: “Red 7”, “White 7”, “BAR” are applied to the left reel 3L). Deriving the advantageous display result on the condition that the stop operation means is operated in accordance with the operation procedure determined in accordance with the set advantageous determination result information in the operation timing of the stop button 12L that can be derived) And can
The specific gaming state control means responds to a type of the set advantageous determination result information when the advantageous determination result information is set by the prior determination means when being controlled to the specific gaming state. Advantageous procedure notifying means (step S936) for notifying the player of information that can specify the operation procedure for deriving the advantageous display result may be included.

  In this case, when the advantageous display result is derived as the display result of the variable display device, the gaming state is controlled to the advantageous state advantageous to the player. When set, it is derived by operating the stop operation means in accordance with the operation procedure determined according to the set type of the advantageous determination result information. Here, when the game state is controlled to a specific game state, information that can specify an operation procedure for deriving the advantageous display result is notified to the player.

  When such information is notified, the player can operate the stop operation means in accordance with the notified information to derive the advantageous display result, so that the player can control the advantageous state. Since it will be involved in the game by its own operation, the interest of the game can be improved. In addition, the operation procedure of the stop operation means for deriving the advantageous display result is not limited to one type, but differs depending on the type of advantageous determination result information set by the predetermining means, so that the advantageous display result is derived. Therefore, the operation procedure of the stop operation means is not constant, and the player's sense of intervention in the game is increased, so that the interest of the game can be improved.

  Note that the winning display result is, for example, a special display result accompanied by a transition to the special gaming state, a small role display result accompanied by the addition of the gaming value, or the gaming value used for setting the number of bets. It is possible to obtain a replay display result that allows the next game to be executed without any change. Here, the advantageous display result may be combined with a small combination display result or a replay display result among the winning display results, and in this case, the advantageous determination result information corresponds to This is determination result information that is set when it is determined that the derivation of the winning display result is permitted.

  The advantageous display result is a display result different from the winning display result, and the stop operation means is set when determination result information indicating that derivation of a predetermined type of winning display result is permitted is set. The display result may be derived when the predetermined winning display result is not derived according to the operation procedure. In this case, the determination result information indicating that the derivation of the predetermined type of winning display result is permitted becomes the advantageous determination result information. The same applies to the disadvantage display result and the disadvantage determination result information described later.

  Further, the information that can identify the operation procedure for deriving the advantageous display result is the advantageous display determination that is set when there are multiple types of advantageous display results and the operation procedure of the stop operation means differs depending on the type. It is good also as what reports the kind of advantageous display result according to the kind of result. Moreover, it is good also as what alert | reports the identification information which comprises the advantageous display result according to the kind of set advantageous display result, and the identification information arrange | positioned in the vicinity. In addition, when a variable display device is configured from a plurality of variable display units and a plurality of stop operation means are provided for each variable display unit, advantageous display results are derived according to the order in which the plurality of stop operation means are operated. In the case of being performed or not derived, the order of operating a plurality of stop operation means may be used. The types of advantageous display results and the stop operation means are information that is not relevant on the surface (for example, characters and background images displayed on the image display device). May be specified by the player (for example, the first operation procedure can be specified if the background image is red, and the second operation procedure can be specified if the background image is white).

In this case,
The specific gaming state determination unit determines whether to control the gaming state to the specific gaming state after the advantageous state ends when the advantageous state is controlled. Steps S924, S925) can be included,
The after-advantageous specific gaming state determination means, when the prior determination means has not determined to permit the derivation of the winning display result, than when it has been determined to permit the derivation of the winning display result It is possible to determine that the gaming state is controlled to the specific gaming state after the advantageous state has ended (the winning probability is 1/8 when lost, and the winning probability is 1 when not lost). / 16384).

  In this case, while being controlled to the advantageous state, it is determined whether or not the specific gaming state is controlled after the advantageous state ends. Here, the probability of being determined to be controlled to the specific gaming state after the advantageous state has ended is higher when it is not determined by the predetermining means that the derivation of the winning display result is permitted. 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. Absent.

The slot machine is
Non-special game number counting means (steps S945 and S952) for counting the number of games that have been digested after the special gaming state is completed,
The specific gaming state control means is configured to control the gaming state to the specific gaming state when the number of games counted by the non-special game number counting means exceeds a predetermined number of games (700 games). Specific game state control means (step S956) may be included.

  The special game state is a game state advantageous to the player, and it is preferable for the player that the number of games between the special game state and the special game state is small. In other words, as the number of games between the special gaming state and the special gaming state increases, it will be disadvantageous for the player, but here, the number of games digested after the end of the special gaming state is the predetermined number of games. If the game state is not controlled to a new special game state, the game state is controlled to a specific game state that is a game state advantageous to another player. For this reason, even when the number of games between the special game state and the special game state increases, the player can be remedied.

The slot machine is
Before the display result of the variable display device is derived for each game, it is determined whether or not the winning display result is allowed to be derived, and the determination result information (winning flag) corresponding to the result of the determination is set. A pre-determining means (step S403);
Derivation control means (step S404) for causing the variable display device to derive a display result according to the determination result information set by the prior determination means;
When a predetermined disadvantage display result (replay 2 to replay 4) is derived as the display result of the variable display device, the disadvantage state control means (step S717) controls the gaming state to the disadvantage state (RT1) unfavorable for the player. And may be further provided. In this case,
The derivation control means, on the condition that the decision result information set by the prior decision means is disadvantageous decision result information (replay 1 + replay 2, replay 1 + replay 3, replay 1 + replay 4). And the above slot machine is
In a game from the end of the special gaming state to the digestion of a specific number of games (15 games), derivation of a winning display result in which the disadvantage determination result information is set by the prior determination means is permitted. The probability to be determined is lower than the probability to determine that the derivation of the winning display result in which the disadvantage determination result information is set by the pre-determining means in the game after the specific number of games is digested is determined. Specific low probability state control means (step S807) for controlling the game state to the specific low probability state (RT3) can be further provided (replay 1 + replay 2, replay 1 + replay 3, replay 1 + replay 4 winning probability) Is 0 in RT3 and 2994/65536 in the normal gaming state).

  In this case, from the end of the special gaming state until the specific number of games is consumed, the disadvantage display result is derived, and the winning decision result information that may be controlled to the disadvantaged state is set. The fact that the derivation of the display result is allowed is controlled to a specific low probability state with a low probability determined by the predetermining means. For this reason, in the game from the end of the special game state to the digestion of the specific number of games, the player can advance the game without worrying too much about the control to the disadvantaged state.

  The disadvantageous state is controlled, for example, from a normal gaming state to an advantageous state or a disadvantageous state that is more advantageous to the player than the normal gaming state, and from the disadvantageous state to the normal gaming state. If the advantageous state is uncontrollable, it may be a gaming state that is more disadvantageous for the player than the advantageous state, and may not necessarily be a gaming state that is disadvantageous for the player than the normal gaming state.

  The RAM 112 is used as a work area when the CPU 111 executes a program. The RAM 112 is separately backed up by a battery and retains stored data as it is even when the power of the slot machine 1 is turned off. The data stored in the RAM 112 is not initialized simply by changing the set value. When the set value is changed, the first reset switch 48 or the second reset switch 93 is operated to turn on the power. Otherwise, it will not be initialized. When the data stored in the RAM 112 is initialized, the normal gaming state is controlled regardless of the gaming state controlled so far.

  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 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 RAM 122 is used as a work area when the CPU 121 executes a program. The RAM 122 is backed up by a battery separately from the RAM 112 of the game control board 101, and stores even when the power of the slot machine 1 is turned off, that is, when a setting value changing operation described later is performed. The data is retained as it is.

  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. An effect mode changeover switch 67 is connected to the effect control board 102, and detection signals of these switches / sensors are input.

  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 regular bonus and the big bonus as the special gaming state, and the winning probability of replay (the total of winning probability of replays 1 to 4 described later) are higher than the normal gaming state. There are RT1, RT2, and RT3 as replay high probability states.

  The types of winning combinations can be broadly divided into special roles with transition to special gaming status (regular bonus, big bonus), small roles with payout of medals, and no need to set the number of bets. There is a re-player who can start the next game. 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 regular bonus is awarded when the combination of “BAR-BAR-Red 7” is aligned on any winning line in the normal gaming state, RT1, RT2, RT3. When the regular bonus is won, the gaming state shifts from the normal gaming state to the regular bonus. When the regular bonus is won at RT1, RT2, RT3, RT1, RT2, RT3 are terminated. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the gaming state is in the regular bonus, the regular bonus medium flag is set in the RAM 112 (including the case where it is provided during the big bonus described below).

  The big bonus (1) is won when the combination of “red 7-red 7-red 7” is aligned on any winning line in the normal gaming state, RT1, RT2, RT3. The big bonus (2) is awarded when a combination of “white 7-white 7-red 7” is aligned on any of the winning lines in the normal gaming state, RT1, RT2, RT3. When the big bonus (1) or the big bonus (2) is won, the gaming state shifts to the big bonus. When the big bonus (1) or the big bonus (2) is won at RT1, RT2, RT3, RT1, RT2, RT3 are terminated.

  In the big bonus, the regular bonus described above is repeatedly provided until the end. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. The big bonus ends when the number of medals paid out to the player exceeds 465. Here, since the maximum payout number per game is 15, the upper limit of the payout medal number in the big bonus is 480. After the big bonus is over, the game state is controlled to RT3 only for the subsequent 15 games (however, until the regular bonus, the big bonus (1), the big bonus (2), and the bells 2 to 4 are won) ).

  Even if the regular bonus, big bonus (1) or big bonus (2) is won in the internal lottery to be described later, “Red 7”, “White 7” and “BAR” within 5 frames for reels 3L, 3C and 3R Since these are not arranged at intervals, these combinations may not be won depending on the operating procedure of the stop buttons 12L, 12C, 12R.

  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 1 wins when a combination of “Bell-Bell-Bell” is aligned on any winning line in any gaming state. Bell 2 wins when a combination of “Red 7-Bell-Bell” is aligned on any winning line in any gaming state. Bell 3 is awarded when a combination of “white 7-bell-bell” is aligned on any winning line in any gaming state. Bell 4 is awarded when the combination of “BAR-Bell-Bell” is aligned on any winning line in any gaming state.

  When winning one of the bells 1 to 4, ten medals are paid out. In addition, when the player wins any of the bells 2 to 4 in the normal gaming state or RT3, the gaming state is controlled to RT2 only for the subsequent 100 games (however, the regular bonus, the big bonus (1 Or until you win the big bonus (2)). Even if a prize is won for Bell 2 to Bell 4 in a normal gaming state or a gaming state other than RT3, the gaming state is not changed. In an internal lottery to be described later, there are cases where the bell 1 wins alone, and where the bell 1 wins either one of the bells 2 to 4. There is no case where Bells 2 to 4 are elected alone.

  Since the “bells” are arranged at intervals of 5 frames or less for all of the reels 3L, 3C, 3R, when the bell 1 is elected alone, the operation procedure of the stop buttons 12L, 12C, 12R is used. Regardless, win the Bell 1 prize. In the case where both of the bell 1 and the bell 2 to the bell 4 are won, the winning of the bell 2 to the bell 4 accompanied by the transition to RT2 is given priority as will be described later, and the stop button 12L Only when it is not possible to win the bells 2 to 4 according to the operation timing, the bell 1 is won.

  Cherry is awarded when the symbol “cherry” is derived to any of the winning lines for the left reel 3L in any gaming state, and two medals are paid out per winning line. When “cherry” is stopped at the upper or lower stage of the left reel 3L, the derivation is made on two pay lines, so that a total of four medals are paid out.

  Replay 1 is awarded when the combination of “JAC-JAC-JAC” is aligned on any winning line in the normal gaming state, RT1, RT2 or RT3. Replay 2 is awarded when the combination of “Red 7-JAC-JAC” is aligned on any of the winning lines in the normal gaming state. Replay 3 is awarded when the combination of “White 7-JAC-JAC” is aligned on any of the winning lines in the normal gaming state. Replay 4 is awarded when a combination of “BAR-JAC-JAC” is aligned on any winning line in the normal gaming state.

  When winning one of Replay 1 to Replay 4, there is no payout of medals, but the next game can be started without setting the number of bets again. This is essentially the same as paying out three medals. In addition, when winning in Replay 2 to Replay 4, the gaming state is controlled to RT1 only during the subsequent 144 games (however, until the regular bonus, big bonus (1) or big bonus (2) is won). ).

  Since “JAC” is arranged at intervals of 5 frames or less for all of the reels 3L, 3C, and 3R, when the replay 1 is selected alone, the operation procedure of the stop buttons 12L, 12C, and 12R is used. Regardless, win Replay 1. In the case where both of the replay 1 and the replay 2 to the replay 4 are won, the winnings of the replay 2 to the replay 4 accompanied by the transition to RT1 are given priority as will be described later, and the stop button 12L Only when the replay 2 to the replay 4 cannot be won due to the operation timing, the replay 1 is won.

  As will be described later, regular bonus, big bonus (1) or big bonus (2) wins are carried over to small roles (watermelon, bell 1 to bell 4, cherry) or replay 1 to replay 4 There is a case. Replay 1 to Replay 4 are derived in preference to regular bonus, big bonus (1) or big bonus (2), so there is no loss, but regular bonus, big bonus (1) or small bonus The derivation of the big bonus (2) will be prioritized.

  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, the roles that are the lottery targets are the same as lot 1 like bell 1 + bell 2, bell 1 + bell 3, bell 1 + bell 4, replay 1 + replay 2, replay 1 + replay 3, replay 1 + replay 4. It may become.

  In accordance with this winning state-specific winning table, in the internal lottery, regular bonus, big bonus (1), big bonus (2), watermelon, bell 1, bell 1 + bell 2, bell 1 + bell 3, bell 1 + bell 4, cherry, The replay 1, replay 1 + replay 2, replay 1 + replay 3, replay 1 + replay 4 determination value numbers are acquired in order according to the gaming state.

  Of course, for regular gaming (including when offered during a big bonus), regular bonus, big bonus (1), big bonus (2), replay 1, replay 1 + replay 2, replay 1 + replay 3. Since 0 is registered as the number of determination values of 3, replay 1 + replay 4, these combinations are not won. Since 0 is registered as the number of determination values of Replay 1 + Replay 2, Replay 1 + Replay 3, and Replay 1 + Replay 4 for the gaming states of RT1 and RT2, these combinations are not won.

  For RT1, RT2, RT3 and the normal gaming state, 0 is registered as the number of judgment values for Bell 1, so that Bell 1 is not won by itself, and is always simultaneously with any of Bells 2 to 4 Winning. However, in RT1 or RT2, even if a prize is won for Bell 2 to Bell 4, the game state is not changed by this, and only the same nine medals as the prize for Bell 1 are paid out. It does not matter whether to win the bell 1 or the bell 2 to the bell 4.

  On the other hand, in RT3 or the normal gaming state, if the player knows which of the bells 2 to 4 is won together with the bell 1, the player can operate the stop button 12L so that the bells 2 to 4 win a prize. The gaming state can be controlled from RT3 or the normal gaming state to RT2. On the other hand, if you don't know which of Bell 2 and Bell 4 is won along with Bell 1, no matter how high the player's skill is, winning a prize for Bell 2 to Bell 4 occurs only at a certain rate Therefore, RT2 cannot control the gaming state from RT3 or the normal gaming state.

  In addition, since 0 is registered as the number of determination values for replay 1 for the normal gaming state, replay 1 is not won independently, and any one of replay 2 to replay 4 is always won simultaneously. . Here, in a normal gaming state, if you do not know which of Replay 2 and Replay 4 is won together with Replay 1, no matter how high the player's skill is, Replay 2 to Replay 4 at a certain rate Wins and is controlled by RT1 from the normal gaming state. On the other hand, if the player knows which one of Replay 2 to Replay 4 is won together with Replay 1, the player can operate the stop button 12L to avoid winning of Replay 2 to Replay 4, and from the normal gaming state RT1 It is possible to prevent the gaming state from being controlled.

  On the other hand, for the gaming state of RT3, 0 is registered as the number of determination values of replay 1 + replay 2, replay 1 + replay 3, and replay 1 + replay 4. In RT3 provided in 15 games after the end of the big bonus, the replay 2 to the replay 4 are not won in this way (therefore, there is no winning), so the gaming state is controlled from RT3 to RT1. There is nothing.

  In the setting value in the example of FIG. 4B, the total number of determination values of the normal gaming state, the regular bonus in RT1, RT2, RT3, the big bonus (1), and the big bonus (2) is 408. The probability of winning either the regular bonus, the big bonus (1) or the big bonus (2) is 408/65536. This reciprocal number 65536/408 (≈160.6) is larger than 144, which is the number of continued games in RT1.

  Also, the total number of replay determination values in the normal gaming state, RT1, RT2, and RT3 (number of replay 1 determination values, number of replay 1 + replay 2 determination values, number of replay 1 + replay 3 determination values, and replay 1+ The total number of replay 4 judgment values) is the same for each set value. However, the total number of replay determination values is 8932 in the normal gaming state, whereas it is 8983 in RT1, 50604 in RT2, and 38542 in RT3.

  The total winning probability of replay in RT1 (probability of winning either Replay 1, Replay 1 + Replay 2, Replay 1 + Replay 3, Replay 1 + Replay 4) is not substantially different from the normal gaming state, and is approximately 1 / It is 7.3. On the other hand, the total winning probability of replay in RT2 is approximately 1 / 1.4. The total winning probability of replay in RT3 is approximately 1 / 1.7.

  By setting the total winning probability of replay in this way, in the normal gaming state and RT1, the medal payout rate is smaller than 1 (that is, internal to the number of medals inserted for setting the bet number). In RT2 or RT3, the total winning probability of replay is higher in RT2 or RT3, so that the medal payout rate becomes larger than 1 (the smaller the number of medals to be paid out in the lottery won in the lottery) That is, the number of medals to be paid out to the small combination won in the internal lottery is larger than the number of medals inserted for setting the bet number). However, the medal payout rate in RT2 is also smaller than the medal payout rate in the regular bonus (including the big bonus). 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 regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag and the replay 1 to replay 4 winning flag are set to overlap, the symbols of the replay 2 to replay 4 are set to the highest. Control is performed so that the symbols of Replay 1 are preferentially arranged on the pay line with priority. Regardless of the operation procedure of the stop buttons 12L, 12C, 12R, the replays 2 to 4 or the replay 1 are won. In this case, the regular bonus, the big bonus (1) or the big bonus (2) is won. Absent.

  When the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag and watermelon winning flag are set in duplicate, the regular bonus, big bonus (1) or big bonus (2) It is controlled so that the symbols are prioritized and aligned on the winning line. When the symbols of regular bonus, big bonus (1) or big bonus (2) cannot be aligned on any winning line due to the operating procedure of the stop buttons 12L, 12C, 12R, "Watermelon" When aligned at the top, "watermelon" can be aligned on the winning line and the watermelon can be won.

  When the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag and the bell 1 to bell 4 winning flag are set in duplicate, first, the regular bonus and the big bonus (1) Alternatively, control is performed so that the big bonus (2) symbol is preferentially aligned on the winning line. If the symbols of regular bonus, big bonus (1) or big bonus (2) cannot be aligned on any winning line due to the operating procedure of the stop buttons 12L, 12C, 12R, the symbols of bell 2 to bell 4 Is controlled with priority on the winning line and then on the winning line.

  If the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag and cherry winning flag are set in duplicate, the regular bonus, big bonus (1) winning flag or big bonus ( 2) Control is performed so that the winning flag pattern is preferentially aligned on the winning line. When the symbols of the regular bonus, big bonus (1) winning flag or big bonus (2) winning flag cannot be aligned on any winning line according to the operating procedure of the stop buttons 12L, 12C, 12R, If the “cherry” can be derived to the upper or lower stage of the reel 3L, the “cherry” is derived to the upper or lower stage to win the cherry.

  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 reels 3L, 3C, 3R are rotated according to the winning flag set according to the result and the operation timing of the stop buttons 12L, 12C, 12R. Will stop and a winning will occur. 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 winning status notification 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 confirmed, and is transmitted when 3 is set as the bet number (including automatic setting based on winnings of replay 1 to replay 4). 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. This indicates the timing at which the reels 3L, 3C, 3R start to rotate, and is transmitted when the rotation of the reels 3L, 3C, 3R is actually started.

  The reel stop command indicates the number of symbols stopped at the middle and the other of the reels 3L, 3C, and 3R, and is transmitted when the reels 3L, 3C, and 3R are stopped. 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 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 an effect, it is difficult to be controlled from RT3 to RT1 in the normal gaming state or RT3, and RT navigation for notifying the player of information for facilitating control by RT2, or to perform RT navigation in the normal gaming state or RT3 There is an RT navigation notification that notifies the player.

  The RT Navi can be shifted to RT2 where the payout rate of medals is larger than 1 for 100 games only when the gaming state is controlled in the normal gaming state or RT3. Replay 2 to Replay 4 in which the payout rate of medals is almost the same as the normal gaming state during the 144 games and the transition to RT1 is eliminated. In this case, the player is informed of which type of the player has been won.

  By performing RT navigation, for example, when it is notified that the bell 2 is won, the player can operate the stop button 12L at a timing when “red 7” is derived to the left reel 3L. Thus, it can be seen that it is possible to control the RT 2 which is advantageous to the player by winning the bell 2 instead of the bell 1. Further, for example, when it is notified that the replay 2 is won, if the player operates the stop button 12L at a timing at which “red 7” is not derived to the left reel 3L, this causes not the replay 2 It can be seen that replay 1 can be won and control to RT1 which is disadvantageous to the player can be avoided.

  In addition, the RT navigation is not necessarily performed if the gaming state is controlled by the normal gaming state or RT3, but it is determined that the RT navigation is performed. When it is not decided to perform RT navigation, even if the gaming state is controlled by the normal gaming state or RT3 and the bell 2 to the bell 4 or the replay 2 to the replay 4 are won, the bell 2 to the bell 4 or It is not notified until which type of replay 2 to replay 4 is won. When it is determined that RT navigation is to be performed, RT navigation notification is performed.

  The determination as to whether or not to perform RT navigation is first made when the gaming state has a big bonus. There are three types of triggers for determining whether or not to perform RT navigation in the big bonus game state, and which of the triggers is selected by the player at the start of the big bonus.

  That is, before the first game of the big bonus is started, the three types of characters A, B, and C are switched and displayed for a certain period of time on the liquid crystal display 4, and the number of bets for the first game of the big bonus is displayed. The character switching display is stopped at the timing when the player performs the determining operation. The type of the character stopped here is a trigger for determining whether to perform RT navigation. The selection of the character type also makes a difference in the effect during the big bonus performed during the big bonus.

  When the character A is selected and the winning probability is 54100/65536, winning the bell 1, an RT navigation lottery for determining whether or not to perform RT navigation is performed. The winning probability of the RT navigation lottery here is 1/32. In addition, even if the RT navigation lottery is won in this case, the RT navigation notification is not performed immediately, and the RT navigation notification is performed at the end of the big bonus.

  When the character B is selected, RT navigation lottery for determining whether or not to perform RT navigation is performed when either a cherry with a winning probability of 6200/65536 or a watermelon with a winning probability of 300/65536 is won. The winning probability of the RT navigation lottery here is 1/4. In addition, when the RT navigation lottery is won in this case, the RT navigation notification is performed when the betting number set for the next game is determined.

  When the character C is selected, the winning probability is 1640/65536, either Bell 1 + Bell 2, Bell 1 + Bell 3, Bell 1 + Bell 4, and based on this, Bell 1 is not Bell 1, but Bell 2 to Bell When winning one of the four, it is determined that RT navigation is performed with a probability of 100% without going through the RT navigation lottery. In this case, the RT navigation notification is immediately made by winning the bells 2 to 4. Further, when the character C is selected and any one of Bell 1 + Bell 2, Bell 1 + Bell 3, and Bell 1 + Bell 4 is won, the liquid crystal display 4 performs a turning effect.

  In addition, when the gaming state is at RT2, whether or not to perform RT navigation after the RT2 is completed after the 100 games are digested and controlled to the normal gaming state depends on each game when the gaming state is at RT2. It is determined by the RT navigation lottery performed. The winning probability of the RT navigation lottery when the gaming state is at RT2 is 1/8 in a game in which all the combinations are lost. Probability of losing to all roles in RT2 is 1439/65536 (provided that regular bonus, big bonus (1) or big bonus (2) wins are not considered), and RT2 continues to be 100 games Therefore, the probability that RT navigation will be performed based on the loss of all the combinations in RT2 is approximately 1/5.

  On the other hand, the winning probability of the RT Navi lottery is 1/16384 in a game where a winning combination (including a regular bonus, a big bonus (1) or a big bonus (2) winning is carried over) is included. . The probability that RT navigation will be determined based on winning of some role in RT2 is only about 1/160. When it is determined that RT navigation is performed when the gaming state is RT2, RT navigation notification is performed at the end of the RT2.

  Furthermore, if it is not decided to perform RT navigation in a game that has consumed more than 700 games after the regular bonus or big bonus game state ends, the fact that RT navigation notification is automatically performed (that is, 100%) Is determined). In this case, RT navigation notification is performed at that time.

  The RT navigation notification is performed by displaying a predetermined image on the liquid crystal display 4, but the RT navigation notification during the big bonus or at the end of the big bonus is selected by the player at the start of the big bonus. This is done by displaying an image of a character of a type. RT navigation notification performed at the end of RT2 and RT navigation notification performed after the completion of the regular bonus or big bonus by 700 games or more are performed by displaying an image of a predetermined character.

  In addition, the RAM 122 of the effect control board 102 is provided with an inter-bonus game counter for counting the number of digested games after the regular bonus or big bonus game state ends. The RAM 122 also has an area for storing the character type selected by the player at the start of the big bonus. The RAM 122 is provided with an area for setting an RT navigation flag indicating that RT navigation is determined and RT navigation notification has already been performed. The RT navigation flag is deleted when the game state is controlled from the next game to regular bonus, big bonus, RT1 or RT2.

  When it is determined that RT navigation is performed when character A or character B is selected in the big bonus, or when RT navigation is determined in RT2, RT navigation notification is not performed immediately. In these cases, it is determined that the RT navigation is performed, but the RAM 122 is also provided with areas for setting the A notification flag, the B notification flag, and the R notification flag indicating that the RT navigation notification has not been performed yet. It has been.

  Furthermore, in the RAM 122 of the effect control board 102, it is necessary to determine the game state other than the timing at which the game state command is received. Therefore, 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, processing in the slot machine 1 according to this embodiment will be described. In the slot machine 1, the game is progressed by repeatedly performing the game process one game at a time. For this purpose, the game must be in a state where the game can be progressed. In order to be able to advance the game, the set value of the normal range is stored in a predetermined area of the RAM 112 while the control unit 110 including the CPU 111 is activated, and the data stored in the RAM 112 is abnormal. There is no condition.

  FIG. 5 is a flowchart showing a startup process executed by the CPU 111 of the game control board 101. This activation process is a process performed when a reset signal is input from the reset circuit of the game control board 101 and the control unit 110 is activated. Since the reset signal is a signal that is output when the power is turned on and when the operation of the control unit 110 is stagnant, the activation process is accompanied by the activation of the control unit 110 that accompanies power-on and a malfunction of the control unit 110. This process is performed when restarting.

  In the startup process, first, the built-in device, peripheral IC, stack pointer, and the like are initialized (step S101), and access to the RAM 112 is permitted (step S102). Then, it is determined whether or not the setting key switch 92 is in an ON state (step S103). If the setting key switch 92 is not ON, the RAM parity is calculated based on all the data stored in the RAM 112 except the parity storage area (step S104).

  Next, the RAM parity calculated here is compared with the RAM parity stored in the parity storage area, that is, the RAM parity calculated and stored at the previous power-off (step S105), and both RAM parities match. Whether or not the data stored in the RAM is normal (step S106).

  If the RAM parities do not match in step S106, the data stored in the RAM 112 is not normal, and the routine proceeds to the RAM abnormality error processing shown in FIG. If the RAM parities match, the data stored in the RAM 112 is normal, so the register stored in the stack area is restored (step S107), the interrupt prohibition is canceled (step S108), Return to the process before turning off the power.

  If the setting key switch 92 is on in step S103, it is further determined whether or not the first reset switch 48 or the second reset switch 93 is on (step S109). If the first reset switch 48 or the second reset switch 93 is not in the ON state, even if the setting key switch 92 is in the ON state, the first reset switch 48 or the second reset switch 93 is not in the ON state. Depending on whether or not the RAM abnormality error code is set, it is determined whether or not the startup process has been performed after the RAM abnormality error (step S110).

  If the RAM abnormality error code is set, the data in the RAM 112 remains not normal data, so that the routine again proceeds to the RAM abnormality error processing shown in FIG. If the RAM abnormality error code is not set, there is no problem with the data in the RAM 112, and only the setting value may be changed, so the process proceeds to step S113.

  On the other hand, if the state of the first reset switch 48 or the second reset switch 93 is ON in step S109, the data stored in the RAM 112 except for the area in use and the area for storing the set value in the stack area. Are initialized (step S111). Furthermore, an initialization command indicating that the data in the RAM 122 has been initialized is generated and transmitted to the effect control board 102 (step S112). Then, the process proceeds to step S113.

  In step S113, the setting change process shown in FIG. 6 is executed to set a new setting value and store it in a predetermined area of the RAM 112. When the prohibition of interruption is canceled after the setting change process is completed (step S114), the game can be progressed and the process proceeds to the game control process.

  FIG. 6 is a flowchart showing in detail the setting change process executed by the CPU 111 in step S113. In the setting change process, first, a setting changing flag indicating that the setting changing mode is being set is set in a predetermined area of the RAM 112 (step S201). Next, the setting value stored in the setting value storage area of the RAM 112 is read and temporarily stored in the work area of the RAM 112 (step S202).

  Next, it is determined whether or not the read set value is in a normal range of 1 to 6 (step S203). If the set value is in the normal range, the process proceeds to step S205. If the set value is not within the normal range (including the case where the RAM abnormality error processing has been performed due to the abnormality of the set value and the case where the set value is added in the next step S206 and becomes 7 after exceeding the normal range) The read set value is corrected to 1 (step S204), and the process proceeds to step S205.

  In step S205, it is determined whether an operation of the setting switch 91 has been detected. When the operation of the setting switch 91 is detected, the read setting value is incremented by 1 (step S206). Then, returning to the process of step S203, if the set value is 7 as a result of the addition, the set value is corrected to 1 in step S204. If the operation of the setting switch 91 is not detected, it is determined whether or not the operation of the state switch 41 is detected (step S207). If the operation of the start switch 41 is not detected, the process returns to the process of step S203, and again enters the state of waiting for the detection of the operation of the setting switch 91 and the start switch 41.

  When the operation of the start switch 41 is detected in step S207, the changed setting value selected at that time is stored in the setting value storage area of the RAM 122 and the setting value is confirmed (step S208). Thereafter, the process waits until the setting key switch 92 is turned off (step S209).

  If it is determined in step S209 that the setting key switch 92 has been turned off, the setting changing flag set in step S201 is cleared (step S210). Then, the setting change process ends, and the process returns to the flowchart of FIG. Returning to the flowchart of FIG. 5, after the prohibition of interrupt is canceled in step S <b> 114, the game can be progressed and the game control process is started.

  FIG. 7 is a flowchart showing in detail the RAM abnormality error process executed by the CPU 111 of the game control board 101. In the RAM abnormality error process, the game number display unit 51 is controlled to display the RAM abnormality error code on the game number display unit 21 (step S301), and then the process proceeds to a loop process in which no process is performed. It should be noted that the RAM abnormality error processing shown in FIG. 7 is also performed when an abnormality in the set value or an abnormality in the number of bets is detected during an internal lottery described later.

  As described above, in the startup process, when the setting key switch 92 is not in the ON state, the data stored in the RAM 112 is compared by comparing the RAM parity calculated at the time of power-off with the RAM parity calculated at the time of startup. It is determined whether or not it is normal, and the routine proceeds to RAM abnormality error processing. In the RAM abnormality error process, since the RAM abnormality error code is displayed on the game number display unit 21, the process proceeds to a loop process in which no process is performed, so that the progress of the game is disabled.

  If the RAM parity does not match, the interrupt is not permitted. Therefore, once the process proceeds to the RAM abnormality error process, the setting key switch 92 is activated in the ON state until the interrupt prohibition is canceled. Even if the power is cut off, no power interruption processing is performed. That is, since no new RAM parity is calculated and stored in the power interruption processing, even if the control unit 110 is activated, the setting key switch 92 is turned on, the first reset switch 48 or the second reset switch 93. Since the RAM parities do not always match except when activated in a state where is turned ON, the control unit 110 cannot be activated to start (resume) the game.

  Once the RAM abnormal error state is entered, the setting key switch 92 is turned on, the first reset switch 48 or the second reset switch 93 is turned on, data in the RAM 112 is cleared, and setting change processing is further performed. Until the new setting value is selected / set by operating the setting switch 91, the game cannot be progressed. That is, after the transition to the RAM abnormal error state, the data in the RAM 112 is cleared, and the state where the game cannot be progressed is canceled on the condition that the setting value is newly selected / set by operating the setting switch 91. The game can be started (restarted).

  On the other hand, even if the setting key switch 92 is in the ON state, if the first reset switch 48 or the second reset switch 93 is started in the OFF state, the data in the RAM 112 is not cleared and only the new setting value is selected and set. Is possible. However, if the setting key switch 92 is ON and the first reset switch 48 or the second reset switch 93 is OFF while being controlled to the RAM abnormality error state, the RAM abnormality error processing is controlled from the beginning. New setting values cannot be selected or set. Also, the RAM abnormal error state controlled by the fact that the set value or the number of bets is not appropriate in the internal lottery is not canceled unless the data in the RAM 112 is cleared and a new set value is set.

  As described above, when the game can be progressed, the game processing is repeated one by one in the slot machine 1. Hereinafter, each game in the slot machine 1 will be described. The “game” in the slot machine 1 is, in a narrow sense, from the operation of the start lever 11 to the stop of the reels 3L, 3C, 3R. Since the bet number before the operation is set, the medals are paid out and the game state is shifted after the reels 3L, 3C, and 3R are stopped, these accompanying processes are also included in the “game” in a broad sense. . It should be noted that the transmission of commands from the game control board 101 to the effect control board 102 will be described only for those necessary for the description of the present invention, and the description of the transmission of other commands will be omitted.

  FIG. 8 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, an initial process including a process of clearing a predetermined area of the RAM 112 is first performed (step S401).

  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. BET processing for instructing start is performed (step S402). 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 S403). 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 S404). 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 rotation of the reels 3L, 3C, 3R is started and stopped, a reel rotation command and a reel stop command are transmitted to the effect control board 102, respectively. Details of the reel rotation process will be described later.

  When the driving of each of the reels 3L, 3C, 3R is stopped, in the display mode at the time of stopping, is any of the above-mentioned role symbols derived and displayed on the winning line according to the bet number set in the BET process in step S402? A winning determination process for determining whether or not is performed (step S405). 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 S406). 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 S403 will be described in detail. FIG. 9 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S403. In the lottery process, it is determined whether or not the gaming state is the big bonus depending on whether or not the big bonus flag is set in the RAM 112 (step S501). If the gaming state is not the big bonus, the process proceeds to step S504 as it is.

  If the gaming state is in the big bonus, it is determined whether the gaming state is in the regular bonus depending on whether the regular bonus flag is set in the RAM 112 (step S502). If the game state is not in the regular bonus, it is the first game of the big bonus, or the game is a game when the regular bonus for one set in the big bonus has ended and the big bonus has not ended yet. The regular bonus medium flag is set to the game state, and the gaming state is controlled to the regular bonus (step S503). Then, the process proceeds to step S504. If the gaming state is in the regular bonus, the process proceeds to step S504 as it is.

  In step S504, by outputting a sampling command, the random number generated by the random number generation circuit 115 is extracted by the sampling circuit 116 and 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, corresponding to the current gaming state, the lottery target combination registered in the gaming state-specific winning combination table of FIG. 4B is sequentially read (step S505). Next, the number of determination values corresponding to the gaming state and setting value read for the lottery target combination is acquired (step S506). 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 S507). 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 S508).

  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 S509). If there is something that has not yet been processed, the process returns to the process of step S505, and the processing is continued 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 S513.

  If an overflow has occurred, it is determined whether or not the lottery target combination read in the previous step S505 is a regular bonus, a big bonus (1), or a big bonus (2) (step S510). If it is neither the regular bonus, the big bonus (1), nor the big bonus (2), the process proceeds to step S512 as it is.

  If the regular bonus, the big bonus (1), or the big bonus (2) is selected, the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is already set in the RAM 112 ( That is, it is determined whether or not the previous game has been carried over (step S511). If the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set, the process proceeds to step S513.

  If none of the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag are set, the process proceeds to step S512. In step S514, the winning flag of the lottery target combination read in step S505 immediately before is set in the RAM 112. Here, the lottery subject is neither a regular bonus, a big bonus (1) or a big bonus (2), but a regular bonus winning flag, a big bonus (1) winning flag or a big bonus (2) winning flag is already set. If so, the winning flag of the current lottery target role is set over the already set regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag. Further, for example, when the lottery target role is Bell 1 + Bell 2, a Bell 1 winning flag and a Bell 2 winning flag are set. Then, the process proceeds to step S513.

  In step S 513, a winning status notification command is generated according to the setting status of the winning flag in the RAM 112 and transmitted to the effect control board 102. Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel rotation process in step S404 will be described in detail. FIG. 10 is a flowchart showing in detail the reel rotation process executed by the CPU 111 in step S404. In the reel rotation process, first, it is determined whether or not a wait time (for example, about 4.1 seconds) has elapsed since the reel rotation start time of the previous game (step S601), and if the wait time has not elapsed, Wait until the wait time has elapsed. If the wait time has elapsed, the timing of the wait time is newly started (step S602).

  Next, the work initialization code at the time of starting the rotation of the reel motor is set in the register, and the rotation of the reel is started (step S603). Here, a reel rotation command indicating that the reels 3L, 3C, and 3R have started rotating is generated and transmitted to the effect control board 102 (step S604). Then, with reference to the table index, the table creation data is identified, and based on the identified table creation data, a stop control table corresponding to the game state of the game, the internal winning situation, and the other reels stop situation is created. Then, it is created for each reel being rotated (step S605), and the work initialization code at the time of completion of stop preparation is set in the register (step S606). Thereby, the operation of the stop buttons 12L, 12C, and 12R becomes valid.

  Next, it is determined whether or not any valid operation of the stop buttons 12L, 12C, and 12R has been detected (step S607). If no stop button operation is detected, it is determined whether or not a reel rotation error (an error determined when the reel reference position is not detected by the reel sensors 3SL, 3SC, 3SR for a certain period or more) has occurred. (Step S608). If no reel rotation error has occurred, the process returns to step S607.

  If it is determined in step S608 that a reel rotation error has occurred, an error code indicating the reel rotation error is set in the register (step S609), and the process proceeds to a predetermined error process (step S610). Along with this, the rotation of the reels 3L, 3C, 3R is also temporarily stopped. If the error is released, the process returns to step S603 again, and the rotation of the reels 3L, 3C, 3R is resumed.

  If the operation of the stop button 12L, 12C, or 12R is detected in step S607, the reel motor (any of 3ML, 3MC, and 3MR) corresponding to the operated stop button from the reel reference position at that time is detected. The number of steps (the number of steps at the stop operation position) is acquired and set to the work corresponding to the stop reel (step S611). Here, a reel stop command indicating the type of reel to be stopped and the symbols to be stopped for the reel is generated and transmitted to the effect control board 102 (step S612). Thereafter, the process waits until the rotation of the reel (3L, 3C, or 3R) corresponding to the operated stop button stops (step S613).

  When the rotation of the reel (3L, 3C, or 3R) corresponding to the operated stop button stops, it is determined whether or not all of the reels 3L, 3C, and 3R have stopped (step S614). If the rotation of the reels 3L, 3C, 3R is not stopped, the process returns to step S605. If the rotation of all the reels 3L, 3C, 3R is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  Next, the winning determination process in step S405 will be described in detail. FIG. 11 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S405. In the winning determination process, winning combinations corresponding to the gaming state are read in order from the beginning (step S701). 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 S702).

  If the symbol combination of the combination is complete, a winning flag for the combination is set in the RAM 112 (step S703), and the process proceeds to step S704. If the symbol combination of the combination is not complete, the process proceeds to step S704 as it is. In step S704, it is determined whether or not there is a combination that has not yet been determined as a winning determination among the combinations according to the gaming state. If there is a winning combination that has not yet been determined for winning, the process returns to step S701, 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 targeted for winning determination, whether or not the replay 1 winning flag is set in the RAM 112 is determined next (step S705). . If the player has won the replay 1, a replay game in-progress flag is set in the RAM 112 (step S706). 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 S719.

  If the replay 1 is not won, it is determined whether or not the big bonus (1) is won according to whether or not the big bonus (1) winning flag is set in the RAM 112 (step S707). If the big bonus (1) has been won, the big bonus medium flag is set in the RAM 112 and the big bonus (1) winning flag set in the RAM 112 is erased. Also, the values of the RT1 counter, RT2 counter, and RT3 counter in the RAM 112 are all initialized to 0 (step S708). Then, the process proceeds to step S719.

  If the big bonus (1) has not been won, it is determined whether or not the big bonus (2) has been won depending on whether or not the big bonus (2) winning flag is set in the RAM 112 (step S709). If the big bonus (2) is won, the big bonus medium flag is set in the RAM 112 and the big bonus (2) winning flag set in the RAM 112 is deleted. Also, the values of the RT1 counter, RT2 counter, and RT3 counter in the RAM 112 are all initialized to 0 (step S710). Then, the process proceeds to step S719.

  If the big bonus (2) has not been won, whether or not the regular bonus has been won is determined based on whether or not the regular bonus winning flag is set in the RAM 112 (step S711). If the regular bonus is won, the regular bonus medium flag is set in the RAM 112 and the regular bonus winning flag set in the RAM 112 is erased. Also, the values of the RT1 counter, RT2 counter, and RT3 counter in the RAM 112 are all initialized to 0 (step S712). Then, the process proceeds to step S719.

  If the regular bonus is not won, neither the regular bonus medium flag nor the big bonus medium flag is set in the RAM 112, and the game state in the current game depends on whether the RT1 counter and the RT2 counter are both 0. It is determined whether the game state is normal or RT3 (step S713). If the game state in the current game is neither the normal game state nor RT3, the process directly proceeds to step S719.

  If the game state in the current game is the normal game state or RT3, whether or not the player has won any of Bells 2 to 4 depending on whether the winning flag of Bells 2 to 4 is set in the RAM 112 Is determined (step S714). If any one of Bells 2 to 4 is won, 101 is set as the initial value of the RT2 counter of the RAM 112 and the value of the RT3 counter is initialized to 0. Here, 101 is set instead of 100 which is the number of continuing games of RT2, because the value of the RT2 counter is decremented by 1 in the current game in step S815 (step S715). Then, the process proceeds to step S719.

  If none of the bells 2 to 4 has been won, it is determined whether or not one of the replays 2 to 4 has been won, depending on whether or not the winning flag for replays 2 to 4 is set in the RAM 112 ( Step S716). If any of Replay 2 to Replay 4 has not been won, the process proceeds to step S719.

  If any of Replay 2 to Replay 4 is won, 145 is set as the initial value of the RT1 counter of RAM 112 and the value of the RT3 counter is initialized to 0. Here, 145 is set instead of 144 which is the number of continuing games of RT1, because the value of the RT1 counter is subtracted by 1 in the current game in step S813 (step S717). Further, a replay game in-progress flag is set in the RAM 112 (step S718). 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 S719.

  In step S719, 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 S406 will be described in detail. FIG. 12 is a flowchart showing in detail the payout process executed by the CPU 111 in step S406. In the payout process, it is determined whether or not there has been a small prize winning accompanied by a medal payout depending on whether or not any of the watermelon, bell 1 to bell 4 and cherry winning flags is set in the RAM 112 (step S801). If the small role is not won, the process proceeds to step S803 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 S802). Then, the process proceeds to step S803.

  In step S803, it is determined whether or not the game state of the game is a big bonus depending on whether or not the big bonus flag is set in the RAM 112. However, when the big bonus (1) or big bonus (2) winning flag is set in the RAM 112, it is a big bonus (1) winning or a big bonus (2) winning in the game, and the game Since the game state is not a big bonus, even if the big bonus medium flag is set, it is not determined that the big bonus is being performed. If the game state of the game is not a big bonus, the process proceeds to step S808.

  If it is determined that the big bonus is in progress, the counter provided in the RAM 112 counts the total number of medals paid out after the big bonus starts (step S804). As a result of this count, it is determined whether or not the total number of medals paid out exceeds 465 (step S805). If the total number of medals paid out does not exceed 465, the process proceeds to step S808.

  When the total number of paid-out medals exceeds 465, the big bonus medium flag set in the RAM 112 is erased, and the counter value for counting the total number of paid-out medals is initialized to 0 (step S806). ). Since the big bonus is ended here, 15 which is the maximum number of continued games of RT3 is set in the RT3 counter of the RAM 112 (step S807), and the process proceeds to step S811.

  In step S808, it is determined whether or not the game state of the game is a regular bonus (including a case where a big bonus is provided) depending on whether or not the regular bonus flag is set in the RAM 112. However, if the regular bonus winning flag is set in the RAM 112, it is a regular bonus winning in the game, and the game state of the game is not a regular bonus, so the regular bonus flag is set. Even if it is, it is not determined that the regular bonus was in effect.

  If the game state of the game is a regular bonus, the counter provided in the RAM 112 starts the regular bonus (after a new regular bonus starts in the big bonus) The number of digest games and the number of winning games are counted (step S809). As a result of this counting, it is determined whether the number of winning games in the regular bonus has reached 8 or the number of digested games in the regular bonus has reached 12 (step S810).

  If the number of winning games in the regular bonus is 8 or the number of digested games in the regular bonus is 12, the process proceeds to step S811. If the number of winning games in the regular bonus is not eight and the number of digest games in the regular bonus is not twelve, the process proceeds to step S818. In step S811, 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 S818.

  If the game state of the game is not a regular bonus in step S808, it is determined whether the RT1 counter value in the RAM 112 is 0 (step S812). If the RT1 counter value is not 0, the RT1 counter value is decremented by 1 (step S813), and the process proceeds to step S818. If the value of the RT1 counter is 0, it is determined whether or not the value of the RT2 counter in the RAM 112 is 0 (step S814). If the RT2 counter value is not 0, the RT2 counter value is subtracted by 1 (step S815), and the process proceeds to step S818. If the value of the RT2 counter is 0, it is determined whether or not the value of the RT3 counter in the RAM 112 is 0 (step S816). If the RT3 counter value is not 0, the RT3 counter value is subtracted by 1 (step S817), and the process proceeds to step S818. If the value of the RT3 counter is 0, the process directly proceeds to step S818.

  In step S818, if the watermelon winning flag, the bell 1 winning flag to the bell 4 winning flag, the cherry winning flag, and the replay 1 winning flag to the replay 4 winning flag are set in the RAM 112, these are deleted. The big bonus (1) winning flag, the big bonus (2) winning flag, and the regular bonus 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 S703, it is deleted.

  Next, based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the values of the RT1 counter, the RT2 counter, and the RT3 counter, a gaming state command indicating a gaming state to be applied in the next game is generated. It transmits to the control board 102 (step S819). Then, the payout process is terminated, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 8, 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 shifts the game state between the normal game state, RT1, RT2, RT3, regular bonus, and big bonus, and the progress of the game In response, a command is transmitted to the effect control board 102. On the other hand, based on the command received from the game control board 101, the CPU 121 of the effect control board 102 selects an effect during the big bonus, and performs an effect process including the normal gaming state and RT navigation in RT3. ing. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  13 to 15 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 S901). When any command is received from the game control board 101, it is determined what kind of the received command is (step S902).

  When the received command type is the BET command transmitted in step S402, the game state to be started from now is referred to with reference to the game state for two times stored in the RAM 122 in step S943 (described later) of the previous game. It is determined whether or not it is the first game after the end of the big bonus (step S903). If it is the first game after the end of the big bonus, the character switching display started at step S947 (described later) and performed on the liquid crystal display 4 is stopped (step S904). Then, information indicating the type of the stopped character is stored in the RAM 122 (step S905).

  If the game to be started is not the first game after the end of the big bonus, it is determined whether or not the B notification flag is set in the RAM 122 by RT navigation winning in the selection of the character B (step S906). 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 indicated by the winning information command received in the previous game (step S907).

  If the watermelon or cherry is won in the previous game, RT navigation notification is given on the liquid crystal display 4 by the effect by the character B (step S908), and the process proceeds to step S909. If neither watermelon nor cherry has been won in the previous game, RT navigation notification is not performed (although RT navigation is performed), the process proceeds to step S909. In step S909, the B notification flag set in the RAM 122 is erased, and an RT navigation flag is set to perform RT navigation after the end of the big bonus. Then, the process returns to step S901. If the B notification flag is not set in step S906, the process directly returns to step S901.

  If the received command type is the winning status notification command transmitted in step S513, the game state of this time is referred to by referring to the game state for two times stored in the RAM 122 in step S943 (described later) of the previous game. It is determined whether or not the gaming state at is a big bonus (step S910). If the game state in the current game is a big bonus, an effect during the big bonus is performed according to the character type stored in step S905 (step S911).

  Next, it is determined whether or not the character type stored in step S905 is the character A, and the received winning status notification command indicates that only the bell 1 is won in the current game (step S912). ). If the character type is character A and only the bell 1 is won, RT navigation lottery is performed by random number lottery with a winning probability of 1/32 (step S913), and it is determined that RT navigation is performed as a result. It is determined whether it has been performed (step S914). If it is determined to perform RT navigation, the A notification flag is set in the RAM 122 (step S915), and the process returns to step S901. If it is determined not to perform RT navigation, the process directly returns to step S901.

  If the character type is not character A, or the winning status notification command does not indicate that only bell 1 is won, the character type stored in step S905 is character B, and It is determined whether or not the received winning status notification command indicates that watermelon or cherry is won in the current game (step S916).

  If the character type is character B and watermelon or cherry is won, RT navigation lottery is performed by random number lottery with a winning probability of 1/4 (step S917), and it is determined that RT navigation is performed as a result. It is determined whether it has been done (step S918). If it is determined to perform RT navigation, the B notification flag is set in the RAM 122 (step S919), and the process returns to step S901. If it is determined not to perform RT navigation, the process directly returns to step S901.

  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 S905 is character C, and It is determined whether or not the received winning status notification command indicates that one of the bells 2 to 4 is won in the current game (step S920).

  If the character type is character C and any one of bells 2 to 4 is selected, the liquid crystal display 4 performs a turning effect by displaying an image of the character C (step S921). Then, the process returns to step S901. If the character type is not character C, or if the winning status notification command does not indicate any of bells 2 to 4, the process directly returns to the process of step S901.

  If the game state of the current game is not a big bonus in step S910, the game state in the current game is further referenced with reference to the game state for two times stored in the RAM 122 in step S943 (described later) of the previous game. Is RT2 (step S922). If the game state in the current game is RT2, it is determined whether or not the received winning status notification command indicates that no winning combination has been won in the current game (step S923).

  If a winning combination is won in this game, RT navigation lottery is performed by random lottery with a winning probability of 1/16384 (step S924). Then, the process proceeds to step S926. If no winning combination is won in this game, RT navigation lottery is performed by random lottery with a winning probability of 1/8 (step S925). Then, the process proceeds to step S926. In step S926, it is determined whether RT navigation is determined in step S924 or S295. If it is determined to perform RT navigation, an R notification flag is set in the RAM 122 (step S927), and the process returns to step S901. If it is determined not to perform RT navigation, the process directly returns to step S901.

  If the game state in the current game is not RT2 in step S922, the game state in the current game is set to RT1 with reference to the game state for two times stored in the RAM 122 in step S943 (described later) of the previous game. Is determined (step S928). If the gaming state in the current game is not RT1, it is further determined whether or not the gaming state in the current game is a regular bonus (not provided during the big bonus) (step S929). If the game state in this game is RT1 or a regular bonus, the process directly returns to step S901.

  If the game state in this game is not a regular bonus, it is determined whether or not the received winning status notification command indicates a winning of any of Bells 2 to 4 (always winning winning with Bell 1). Step S930). If either of the bells 2 to 4 is won, it is determined whether or not the RT navigation flag is set in the RAM 122 (step S931).

  If the RT Navi flag is set in the RAM 122, information that can identify which of the bells 2 to 4 is specified is displayed on the liquid crystal display 4 to notify the player (step S932). . Then, the process returns to step S901. If the RT navigation flag is not set, any one of the bells 2 to 4 is won together with the bell 1, but information which cannot be specified until which of them is won is displayed on the liquid crystal display 4. To the player (step S933). Then, the process returns to step S901.

  If none of the bells 2 to 4 has been won in step S930, whether the received winning status notification command indicates one of the replays 2 to 4 (always winning with replay 1 and duplicate). It is determined whether or not (step S934). If none of Replay 2 to Replay 4 has been won, the process returns to Step S901. If any one of Replay 2 to Replay 4 is won, it is determined whether or not the RT Navi flag is set in RAM 122 (step S935).

  If the RT Navi flag is set in the RAM 122, information that can specify which of Replay 2 to Replay 4 is selected is displayed on the liquid crystal display 4 to notify the player (Step S936). . Then, the process returns to step S901. If the RT Navi flag is not set, any one of Replay 2 to Replay 4 is selected together with Replay 1, but information that cannot be specified until which of them is selected is displayed on the liquid crystal display 4. To the player (step S937). Then, the process returns to step S901.

  If the received command type is the winning information command transmitted in step S719, the game state for the current game is referred to with reference to the gaming state for two times stored in the RAM 122 in step S943 (described later) of the previous game. It is determined whether or not the gaming state is a big bonus (step S938). If the gaming state in the current game is a big bonus, it is determined whether or not the RT navigation flag is set in the RAM 122 (step S939).

  If the RT navigation flag is not set, it is determined whether or not the character type stored in step S905 is character C and the received winning information command indicates a winning of bells 2 to 4 (step S940). . If any of the bells 2 to 4 has been won, the player is notified by displaying a predetermined image of the character C on the liquid crystal display 4 that the RT navigation is to be performed after the end of the current big bonus. (Step S941). Further, an RT navigation notification flag is set in the RAM 122 (step S942). If the character C is selected and won the bells 2 to 4, RT navigation is performed with a probability of 100% after the end of the big bonus. This is an RT navigation lottery with a winning probability of 100%. It is substantially the same as that won. Then, the process returns to step S901.

  If the game state in this game is not a big bonus in step S938, if the RT navigation flag has already been set in the RAM 122 in step S939, or if the character type is not character C in step S940, If it does not indicate that any of Bells 2 to 4 has been won, the process directly returns to step S901.

  If the received command type is the gaming state command transmitted in step S819, 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 S943). Next, it is determined whether or not the game state of the next game indicates a big bonus or a regular bonus (step S944).

  If the game state of the next game is a big bonus or a regular bonus, the value of the inter-bonus game counter in the RAM 122 is initialized to 0 (step S945). Furthermore, with reference to the game state for two times stored in the RAM 122, it is determined whether or not the big bonus starts from the next game (step S946). If the big bonus starts from the next game, the character switching display for switching the characters A, B, and C to be displayed on the liquid crystal display 4 for a certain period is started (step S947). Then, the process returns to step S901. If the big bonus does not start from the next game, the process returns to step S901.

  If the game state of the next game is neither a big bonus nor a regular bonus in step S944, the game state for two times stored in the RAM 122 is referred to and the big bonus or regular bonus (provided during the big bonus is provided in this game). It is determined whether or not the process has ended (step S948). If the big bonus or the regular bonus (not including those provided in the big bonus) has ended in this game, it is determined whether or not the A notification flag is set in the RAM 122 (step S949).

  If the A notification flag is not set, the process directly returns to step S901. If the A notification flag is set, since the RT navigation lottery is won by the end of the big bonus with the character A selected, a predetermined image of the character A indicating that the RT navigation is performed is displayed on the liquid crystal display. 4 is displayed to the player (step S950). Further, the A notification flag is deleted from the RAM 122, and the RT navigation flag is set in the RAM 122 (step S951). Then, the process returns to step S901.

  If the big bonus or regular bonus (not including those provided during the big bonus) has not ended in this game, the game counter value between bonuses in the RAM 122 is incremented by 1 (step S952). Then, as a result of this addition, it is determined whether or not the value of the bonus game counter has reached 700 or more, that is, whether or not a game has been played in the normal gaming state, RT1, RT2 or RT3 for 700 games (step). S953).

  If the value of the game counter between bonuses is 700 or more, it is determined whether or not the RT navigation flag is set in the RAM 122 (step S954). If the RT navigation flag is set, the process directly returns to step S901. If the RT navigation flag is not set, the player is notified by displaying a predetermined image on the liquid crystal display 4 that the RT navigation is performed again from here (step S955). Further, an RT navigation flag is set in the RAM 122 (step S956). Then, the process returns to step S901.

  On the other hand, if the value of the inter-bonus game counter is less than 700, the game state for two times stored in the RAM 122 is referred to determine whether the regular bonus, big bonus, RT1 or RT2 starts from the next game. Determination is made (step S957). If the regular bonus, big bonus, RT1 or RT2 starts from the next game, it is determined whether or not the RT navigation flag is set in the RAM 122 (step S958). If the RT navigation flag is not set, the process directly returns to step S901. If the RT navigation flag is set, the RT navigation flag is deleted from the RAM 122 (step S959), and the process returns to step S901.

  If the regular bonus, big bonus, RT1 or RT2 does not start from the next game, it is determined by referring to the gaming state for two times stored in the RAM 122 whether RT2 has ended in the current game ( Step S960). If RT2 has not ended in the current game, the process directly returns to step S901. If RT2 is completed in this game, it is determined whether or not the R notification flag is set in the RAM 122 (step S961).

  If the R notification flag is not set, the process returns to step S901. If the R notification flag is set, the RT navigation lottery is won until RT2 is finished, so that a predetermined image indicating that RT navigation is to be performed is further displayed on the liquid crystal display 4. (Step S962). Further, the R notification flag is deleted from the RAM 122, and the RT navigation notification flag is set in the RAM 122 (step S963). Then, the process returns to step S901.

  If the received command type is the initialization command transmitted in step S112, since the RAM 112 of the game control board 101 is initialized at this time, the RAM 122 of the effect control board 102 is also initialized accordingly. (Step S964). Then, the process returns to step S901.

  If the received command type includes other commands (including a reel rotation command and a reel stop command), a process corresponding to each command type is executed (step S965). Since this is not related to the present invention, a detailed description is omitted, and the process returns to step S901.

  As described above, in the slot machine 1 according to this embodiment, after the regular bonus is finished, it is controlled to the normal gaming state, and after the big bonus is finished, it is changed to the normal gaming state through RT3 of 15 games. Be controlled. When the player wins the bells 2 to 4 in RT3 or the normal gaming state, the gaming state is controlled to RT2, and when the player wins the replays 2 to 4 in the normal gaming state, the gaming state is controlled to RT1. When controlled by RT1 or RT2, it is not directly controlled by RT2 or RT1. If the 100 games are consumed at RT2 or the 144 games are consumed at RT1 without winning the regular bonus, the big bonus (1) or the big bonus (2), the game state is controlled again to the normal gaming state.

  RT2 is a game state that is advantageous to a player whose medal payout rate is greater than 1 because the winning probability of replay is significantly higher than the normal game state. This advantageous RT 2 includes “Red 7”, “White 7”, “White 7”, “Bell 7”, “Bell 1”, “Bell 1”, “Bell 1 + Bell 3”, or “Bell 1 + Bell 4” in the internal lottery. It is possible to control by operating the stop button 12L at a timing at which “BAR” can be derived and winning the bell 2, the bell 3, and the bell 4. If the operation timing of the stop button 12L is not appropriate, even if the winning of the bell 1 + bell 2, the bell 1 + bell 3, or the bell 1 + bell 4 is won, the player wins the bell 1 and the gaming state is not controlled by the RT2.

  Here, if the RT navigation flag is not set in the normal gaming state or RT3, that is, if it is not decided to perform RT navigation, it will win the bell 1 + bell 2, bell 1 + bell 3, or bell 1 + bell 4 However, it is not notified to which of Bell 2 and Bell 4 is won together with Bell 1. In this case, since the player cannot operate the stop button 12L at the timing of reliably winning the bell 2, bell 3 or bell 4, even if there is a possibility of causing the RT 2 to control in the internal lottery, RT2 cannot be controlled at a constant rate.

  On the other hand, if the RT navigation flag is set in the normal gaming state or RT3, that is, if it is determined to perform RT navigation, it is determined which of the bells 2 to 4 is won together with the bell 1. The person is informed. The player operates the stop button 12L at a timing at which one of the bells 2 to 4 that has been informed can win a prize, thereby causing the bells 2 to 4 to win and control the gaming state to RT2. It can be. Thereby, a player can intervene in a game by his / her own operation regarding control to RT2 which is a game state advantageous to the player, and the interest of the game can be improved.

  Depending on whether the bell 1 + bell 2, the bell 1 + bell 3, or the bell 1 + bell 4 is selected, the operation timing of the stop button 12L for winning the bell 2, bell 3, or bell 4 controlled by the RT2 is determined. It is completely different. The player must change the timing of operating the stop button 12L in order to have RT2 control depending on whether the player has won the bell 1 + bell 2, the bell 1 + bell 3, or the bell 1 + bell 4, so that the player In addition to the further increase in the sense of intervention in the game, it is also necessary to have the technicality of timing the operation of the stop button 12L when performing an operation to intervene in the game, so that the interest of the game can be further improved.

  On the other hand, RT1 is a gaming state that is disadvantageous for a player who has a replay winning probability almost the same as a normal gaming state and whose medal payout rate is smaller than one. This disadvantageous RT1 has “Red 7”, “White 7” and “BAR” on the left reel 3L when Replay 1 + Replay 2, Replay 1 + Replay 3 or Replay 1 + Replay 4 are selected. If the stop button 12L is operated at a timing that can be derived and the replay 2, the replay 3, or the replay 4 is awarded, it will be controlled. If the stop button 12L is operated at a timing at which “red 7”, “white 7”, and “BAR” cannot be derived, even if replay 1 + replay 2, replay 1 + replay 3, or replay 1 + replay 4 is won, it will be replay 1 It is not controlled by RT1, which has won the prize and has no possibility of being controlled by RT2 until the end.

  Here, in the normal gaming state, if the RT navigation flag is not set, that is, it is not determined that RT navigation is performed, even if replay 1 + replay 2, replay 1 + replay 3, or replay 1 + replay 4 is won, It is not notified to which of Replay 2 and Replay 4 along with Replay 1 is won. In this case, since the player cannot operate the stop button 12L at a timing at which winning can be reliably avoided in Replay 2, Replay 3 or Replay 4, there is a possibility of causing RT1 to control in the internal lottery. Control to RT1 cannot be avoided at a constant rate.

  On the other hand, if the RT navigation flag is set in the normal gaming state, that is, it is determined that RT navigation is to be performed, the player is informed which of Replay 2 and Replay 4 is won together with Replay 1. Informed. The player operates the stop button 12L at a timing at which the winning of what is informed among the replays 2 to 4 can be avoided, so that the player can win the replay 1 without winning the replays 2 to 4. It is possible to prevent the gaming state from being controlled by RT1. Thus, the player can intervene in the game by his / her own operation with respect to avoiding RT1, which is a gaming state disadvantageous to the player, and the interest of the game can be improved.

  Further, a stop button 12L for avoiding winning of Replay 2, Replay 3, and Replay 4 controlled by RT1, depending on whether Replay 1 + Replay 2, Replay 1 + Replay 3 or Replay 1 + Replay 4 is won. The operation timing is completely different. Depending on whether Replay 1 + Replay 2, Replay 1 + Replay 3, or Replay 1 + Replay 4 is won, the player must change the timing of operating the stop button 12L so that RT1 does not control, and further RT1 As for the avoidance of the game, the player's sense of intervention in the game is further increased, and the technique for timing the operation of the stop button 12L when performing the operation to intervene in the game is also required, so that the interest of the game is further improved Can do.

  In addition, Bell 1 + Bell 2, Bell 1 + Bell 3, or Bell 1 + Bell 4 that may be controlled by RT2, which is advantageous to the player, may be won in both the normal gaming state and RT3. Replay 1 + Replay 2, Replay 1 + Replay 3, or Replay 1 + Replay 4 may be won in the normal gaming state, which may be controlled by RT1, which is disadvantageous to the game, but 15 after the end of the big bonus You will not win at RT3 during the game. Therefore, from the end of the big bonus until the 15 games are consumed, the player expects control to RT2 which is a gaming state without worrying about being controlled by RT1 which is a disadvantageous gaming state. However, the game can be advanced.

  Further, the maximum number of continuous games of RT2 controlled based on the winnings of Bell 2 to Bell 4 is 100 games, and the maximum number of continuous games of RT1 controlled based on the winnings of Replay 2 to Replay 4 is 144 games. is there. On the other hand, the probability of winning the regular bonus, the big bonus (1) or the big bonus (2) in the normal gaming state, RT1, RT2 or RT3 is approximately 1 / 160.6. That is, the expected value of the number of games between bonuses is larger than the maximum number of continued games of RT1 and RT2.

  In particular, even if the RT1 maximum continuous game number is smaller than the expected value of the number of games between bonuses, even if it is once controlled to RT1, the next regular bonus, big bonus (1) or big bonus (2) will be won. By the time, it is controlled again to the normal gaming state, and there are many cases where the chance of controlling by RT2 comes. Therefore, the player's expectation is not greatly impaired. In addition, between the bonuses, RT1 and RT2 can be appropriately controlled.

  By the way, as described above, the winning of Bell 2 to Bell 4 is notified in the normal gaming state so as to be controlled by RT2, or in the normal gaming state so that the control to RT1 is avoided so as to avoid the control to RT1. Whether or not to perform RT navigation for notifying the player is first determined when the gaming state is controlled to the big bonus. When the gaming state is controlled to the big bonus, the effect during the big bonus is performed in each game.

  Here, before the first game of the big bonus is started, the characters A to C are sequentially switched and displayed on the liquid crystal display 4, and the first game of the big bonus is performed by the player's betting number setting operation. When the betting number for the game is determined, the character type displayed at that time is the character type applied to the big bonus medium effect. 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.

  Further, when the big bonus is controlled to determine whether or not to perform RT navigation after the end of the big bonus, when the character A is selected, the winning of the bell 1 is selected, and when the character B is selected, the watermelon or cherry is selected. When the winning character C is selected, the winnings of the bells 2 to 4 are different depending on the type of the selected character. In addition, the probability that RT navigation is determined 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 RT navigation will be performed before the end of the big bonus does not differ greatly regardless of which type of character is selected. Thus, since the selection of the character at the start of the big bonus affects not only mere production but also the progress of the game itself, the player's sense of intervention in the game can be enhanced, thereby improving the interest of the game. .

  Furthermore, when it is decided to perform RT navigation in the big bonus, RT navigation notification is performed to notify the player of this, but the images displayed at the time of RT navigation notification are respectively selected. This is an image of the selected character. Further, the RT navigation notification is performed at the end of the big bonus when the character A is selected, when the bet number for the next game is determined when the character B is selected, and when the character C is selected, the bell 2 ~ Immediately with the winning of the bell 4 and depending on the type of character selected. As described above, the selection of the character at the start of the big bonus also makes a difference in the RT navigation notification method performed when it is determined that the RT navigation is performed. Will be able to.

  Even when the gaming state is controlled to RT2, it is determined whether or not to perform RT navigation in the normal gaming state after the end of RT2. That is, RT navigation lottery is performed in each game when controlled by RT2, and RT navigation is performed in the normal gaming state after the end of RT2 by winning this game. Of course, the RT navigation lottery in games controlled by RT2 has a low probability of winning if any part is won, but wins with a relatively high probability when all the parts are lost. It has become. For this reason, even if the RT2 game fails to win any role, the expectation of winning the RT navigation lottery is increased, so that the player's expectation is not reduced.

  Furthermore, when the number of games digested after the end of the regular bonus or the big bonus is 700 games or more, RT navigation is always performed when controlled to the normal gaming state. This RT navigation makes it easier to control the RT 2 which is advantageous to the player, so that it is possible to provide relief for the excessive number of games between bonuses.

  In addition, since the winning probability of the internal lottery performed in each game differs depending on the set value, if the set value is changed, the winning probability corresponding to the newly set value is set in subsequent games. The internal lottery will be performed. In order to change the setting value, the setting machine switch 92 is turned on to start the slot machine 1, and the setting switch 91 is operated in the setting change mode shifted here to select a desired setting value. It is necessary to set the setting key switch 92 to the OFF state after operating.

  Here, when only the setting key switch 92 is activated to change the setting value, the RAM 112 is not initialized. Therefore, even if the setting value is changed, it is stored in the RAM 112 in addition to the setting value. The data is not changed. For this reason, when only the setting value is changed without turning on the first reset switch 48 or the second reset switch 93, the data relating to the other games remains stored in the RAM 112, so The gaming state controlled before the change is continued in the game after the set value is changed. That is, the change in the set value does not cause a change that is obvious at a glance unlike the change in the gaming state.

  Changing the set value only changes the winning probability of the internal lottery, but there is only a difference as a problem of probability, and as long as the number of digest games after changing the set value is small, the winning of the internal lottery The player cannot predict that the probability has changed, that is, that the set value has been changed. Even if the set value can be predicted to some extent, a considerable number of games have to be played before reaching that point. For this reason, in situations where multiple slot machines are in operation at the amusement store, the player immediately knows that the set value has been changed between the closing and opening of the previous day. As a result, there is no stand that prevents the player from approaching, and the operating rate of each stand does not decrease.

  However, even if only the setting value is changed, the RAM 122 is not initialized, and even if there is no change in the gaming state before and after the setting value is changed, the setting key switch 92 is turned ON, and the first reset switch 48 or the first reset switch 48 or If the 2 reset switch 93 is activated in the ON state, the data stored in the RAM 122 can be initialized. For this reason, it is possible to return to the normal gaming state as needed using the time of changing the set value.

  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, even when any of the characters A, B, and C is selected by the player at the start of the big bonus, or at the end of RT2 or the number of games between bonuses is 700 games. Even in the case of time, although there is a difference in timing, the RT navigation notification is performed by displaying an image on the liquid crystal display 4. However, RT navigation notification may be performed in a manner different from the display of images on the liquid crystal display 4 in some or all of the 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, in the RT navigation, the RT2 that is advantageous to the player is controlled by notifying the type of the winning one of the bells 2 to 4 or the replays 2 to 4 as it is. Therefore, the player can specify the procedure of the stop operation that can avoid the control to RT1 which is disadvantageous to the player. Of course, the information to be notified in the RT navigation is not directly informing the winning result of the internal lottery in this way, but can be controlled by the RT2, and the stop operation that can avoid the control to the RT1. Any information that can identify the procedure of the player can be used, and this information is information that is irrelevant to the winning result of the internal lottery or the stop operation, even if it is the stop operation procedure itself. There may be.

  For example, the background color of the image displayed on the liquid crystal display 4 is red (corresponding to “red 7”), white (“white 7”) corresponding to the winning of bell 2 to bell 4 and replay 2 to replay 4. Corresponding) or black (corresponding to “BAR”), or the character type displayed on the liquid crystal display 4 may be changed. Further, in the left reel 3L, if different symbols are arranged in the vicinity of “red 7”, “white 7”, and “BAR”, such symbols may be notified. In order to avoid winnings of Replay 2 to Replay 4, symbols that are not arranged in the vicinity of the symbols constituting the winning ones of Replay 2 to Replay 4 may be notified.

  In the above embodiment, the replays 2 to 4 for controlling the game state from RT3 to RT1 only win at the same time as the replay 1. On the other hand, the regular bonus, the big bonus (1) and / or the big bonus (2) and the replay 2 to the replay 4 may be won simultaneously. In this case, even if it is controlled to RT1 which is disadvantageous to the player by winning the replay 2 to the replay 4, at this time, the regular bonus, the big bonus (1) and / or the big bonus (2) can be expected to be won. As a result, the player's expectation is not diminished.

  In the above embodiment, in the normal gaming state or RT3, either of the bell 1 and the bell 2 to the bell 4 is won simultaneously in the internal lottery, and the bells 2 to 4 are changed instead of the bell 1 based on this. When derived as a display result of the display device 2, the gaming state is controlled to RT2. On the other hand, when one of the bell 1 and the bell 2 to the bell 4 is simultaneously elected in the normal gaming state or RT3, the bell 1 instead of the bell 2 to the bell 4 is derived as the display result of the variable display device. Sometimes, the gaming state may be controlled to RT2. In this case, when the winning of bell 2 to bell 4 is notified by RT navigation, the stop operation is performed so that the bell 1 is won without winning the notified bell 2 to bell 4, thereby allowing the RT 2 to The gaming state can be controlled.

  The same applies to the relationship between Replay 1 and Replay 2 to Replay 4, and when Replay 1 and Replay 2 to Replay 4 are simultaneously selected in the normal gaming state or RT 3, Replay 1 is not Replay 2 but Replay 4. Is derived as the display result of the variable display device, the gaming state may be controlled to RT1. In this case, when the winning of Replay 2 to Replay 4 is notified by RT Navi, the game state is controlled by RT 1 by performing a stop operation so that the notified Replays 2 to 4 are awarded. It can be avoided.

  Further, the symbol for causing RT2 to control the gaming state may be a symbol derived by losing a winning combination by internal lottery instead of winning a winning combination like Bell 2 to Bell 4. For example, in the normal gaming state or RT3, it is assumed that Bell 2, Bell 3, and Bell 4 are each independently won by internal lottery, and the missed eye 2, the missed eye 3, and the missed eye 4 can be derived at the time of missed, respectively. When it is assumed, the missed eye 2, the missed eye 3, and the missed eye 4 may be used as a symbol for causing the RT 2 to control the gaming state. In this case, when the winning of the bells 2 to 4 is notified by the RT navigation, the stop operation is performed so as to derive the missing eyes 2 to 4 without winning the notified bells 2 to 4. As a result, the gaming state can be controlled by RT2.

  The same applies to the symbols for causing RT1 to control the gaming state. For example, in the normal gaming state, Replay 2, Replay 3, and Replay 4 are each won separately. When the replay removal eye 2 and the replay removal eye 3 can be derived, the replay removal eye 1, the replay removal eye 2, and the replay removal eye 3 may be used as symbols for causing the RT 1 to control the gaming state. In this case, when the winning of Replay 2 to Replay 4 is notified by RT navigation, the gaming state is controlled by RT 1 by performing a stop operation so that the notified Replay 2 to Replay 4 are awarded. Can be avoided.

  Furthermore, the symbols for controlling the RT 2 which is a gaming state advantageous to the player are the replay 1 to the replay 4 and the replay removal points 2 to 4 derived by losing them, which is a disadvantageous gaming state for the player. The symbols to be controlled by RT1 may be Bells 1 to 4 or missing eyes 2 to 4 derived by missing them. In any case, in RT3 controlled only for 15 games after the end of the big bonus, it is not possible to win a winning combination that may cause RT1 to derive a symbol whose gaming state is controlled in the internal lottery. it can.

  In the above embodiment, the symbols of the left reel 3L constituting the display modes of the bells 2 to 4 are “red 7”, “white 7”, and “BAR”, respectively, and the display modes of the replays 2 to 4 The symbols on the left reel constituting “Red”, “Red 7”, “White 7”, and “BAR”, respectively. Here, with respect to the left reel 3L, “red 7”, “white 7”, and “BAR” are arranged one by one, and the stop button 12L of the stop button 12L can be operated regardless of the order in which the stop buttons 12L, 12C, 12R are operated. By aiming at the operation timing, it was possible to win the bells 2 to 4 or avoid the replays 2 to 4. If the operation timing of the stop button 12 </ b> L is bad, the player does not win the bells 2 to 4 but wins the replays 2 to 4.

  On the other hand, depending on the arrangement of the symbols on the reels 3L, 3C, and 3R, if the stop buttons 12L, 12C, and 12R are operated in a predetermined order, the role to be shifted to RT1 and RT2 is surely won, or other than the predetermined order If the operations are performed in this order, there is a possibility that the winning combination for shifting to RT1 and RT2 may not be won. For example, if three “red 7” s are arranged at intervals of 7 frames for the left reel 3L, the left reel 3L will always win the bell 2 and the replay 2 if it is operated first, but the left reel 3L May not be awarded to Bell 2 or Replay 2 depending on the operation timing.

  Similarly, the symbol combination of the bell 3 is “bell-white 7-bell”, the symbol combination of the replay 3 is “JAC-white 7-JAC”, and three “white 7” are arranged at intervals of 7 frames for the inner reel 3C. In the case of arrangement, it is determined by the order in which the inner reel 3C is operated. When the symbol combination of Bell 4 is “Bell-Bell-BAR”, the symbol combination of Replay 4 is “JAC-JAC-BAR”, and three “BARs” are arranged at intervals of 7 frames on the right reel 3R, It is determined by the order in which the right reel 3R is operated. Here, instead of replay 2 to replay 4, replay 1 is assumed to be an entry pattern to RT 1.

  In this case, in the RT navigation, when the bell 1 + bell 2, bell 1 + bell 3, bell 1 + bell 4, replay 1 + replay 2, replay 1 + replay 3, replay 1 + replay 4 are won, the bells 2 to 4, Or it is good also as what alert | reports only the operation order of stop button 12L, 12C, 12R for making Replay 2 to Replay 4 win reliably. However, even when the type of the winning one of Bell 2 to Bell 4 and Replay 2 to Replay 4 is informed, depending on the type, it is necessary for Bell 2 to Bell 4 or Replay 2 to Replay 4 to win a prize. The player can specify the operation order of the stop buttons 12L, 12C, and 12R.

  Thereby, the player operates the stop buttons 12L, 12C, and 12R according to the notified operation order (or the operation order specified according to the notified type of the combination), so that the bell 2 to the bell 4 are operated. It is possible to reliably win and control RT2, and to make sure that Replay 2 to Replay 4 win and avoid the transition to RT1. In this case, a player with a low skill level can surely perform the transition to RT2 and the avoidance of RT1 in accordance with his / her own operation.

  In the above embodiment, during the predetermined number of games (15 games) after the end of the big bonus, the gaming state is controlled by RT3 instead of the normal gaming state, and RT3 controls the gaming state by RT1 in RT3. Replay 4 was not won in the internal lottery. On the other hand, even before the predetermined number of games are consumed after the end of the big bonus, winning a role that may cause RT1 to derive a game that controls the gaming state as in Replay 2 to Replay 4. There may be.

  Of course, during the predetermined number of games after the end of the big bonus, there is a possibility that RT1 may derive a symbol for controlling the gaming state as in Replay 2 to Replay 4, rather than the game after the predetermined number of games has been consumed. It is preferable to lower the winning combination probability. Even if there is a possibility of winning a role that may cause RT1 to derive a symbol that controls the gaming state for the predetermined number of games after the end of the big bonus, by setting the winning probability low, The player can advance the game while expecting control to RT2 which is an advantageous game state without worrying too much about control to RT1 which is a disadvantageous game state.

  In the above embodiment, when it is determined that RT navigation is to be performed except when the number of digested games after the bonus ends becomes 700 games or more, the RT navigation is controlled to RT1 or RT2 next. (However, until the regular bonus or big bonus is controlled) Once the gaming state is controlled by RT1 or RT2, it is determined that RT navigation will not be performed again. It was never done. In addition, RT navigation was not terminated no matter how many games were consumed unless the game state was controlled by RT1 or RT2 without winning Replay 2 to Replay 4 or Bell 2 to Bell 4.

  On the other hand, if it is determined that RT navigation is to be performed before the number of digested games after the bonus ends reaches 700 games, the determination of performing RT navigation in the big bonus RT navigation may be performed until the predetermined number of games is exhausted. Alternatively, RT navigation may be performed until a predetermined time elapses after it is determined that RT navigation is performed (in the determination that RT navigation during a big bonus is performed after the end of the big bonus).

  Also, RT navigation may be continued until controlled by RT2 without ending even if controlled by RT1. That is, the stop button 12L is operated according to the notification of the winning of the bells 2 to 4 by the RT navigation, and the RT navigation is terminated when controlled by the RT2, but the stop button 12L is notified according to the winning notification of the replays 2 to 4 If the RT1 is controlled by the RT1 without being operated, the RT may be re-navigated in the normal gaming state after the RT1 is ended by the digestion of the 144 game. In this case, it is possible to rescue a player who does not have a sufficient skill and cannot reliably perform the stop operation according to the RT navigation.

  In the above embodiment, in the game from the end of the bonus to the start of the next bonus, the RT navigation is performed only when it is controlled to RT2, except when the number of digested games after the bonus becomes 700 or more. By performing a lottery and winning the game, RT navigation can be performed even in a normal gaming state after RT2 has been completed after 100 games have been consumed. On the other hand, RT navigation lottery is performed even when controlled by RT1, and winning is performed so that RT navigation can be performed even in a normal gaming state after RT1 is ended by digestion of 144 games. Also good.

  In RT navigation lottery performed when controlled by RT1, there is a high probability that RT1 will lose to all the roles in the internal lottery, so RT is a game that lost all roles in the internal lottery like RT2. Instead of increasing the winning probability of the navigation lottery, for example, the winning probability of the RT navigation lottery may be increased in a game that wins (or wins) a specific role such as a watermelon. Thereby, when winning a specific combination in RT1, it is possible to give the player a sense of expectation that RT navigation will be performed, and to further improve the interest of the game.

  In the above embodiment, the value of the inter-bonus game counter is cleared to 0 when winning either the regular bonus or the big bonus, and if this value is 700 or more and the normal gaming state is achieved. RT navigation was supposed to be executed. Of course, in regular bonuses (not including those offered during the big bonus), RT Navi lottery is not performed, so the number of games where RT Navi is not executed may become too large in regular bonus winnings. . Therefore, while the game state is controlled by the regular bonus, the value of the game counter between bonuses is not added, but the value of the game counter between bonuses may not be cleared when the regular bonus is won. Thereby, it can prevent that the period when RT navigation is not performed becomes too long.

  In the above embodiment, before the first game of the big bonus is started, the characters A to C are sequentially switched and displayed on the liquid crystal display 4, and the timing when the bet number for the first game of the big bonus is determined. In accordance with the type of character displayed in, the type of effect in the big bonus is selected. However, the type of performance during the big bonus is not selected by the operation related to the progress of the game like the setting of the number of bets, but the player can be selected by an operation completely independent of the progress of the game. Also good.

  Further, the effect during the big bonus is not a change of the character type displayed on the liquid crystal display 4 that is changed according to the player's selection, but may be an image other than the character. In addition, the image displayed on the liquid crystal display 4 does not change depending on the player's selection, but the sound effect or BGM output in the production during the big bonus may change. Also, the RT navigation notification may be the only effect whose contents are changed in the big bonus according to the player's selection.

  In the above embodiment, whether or not to perform RT navigation at a different opportunity is determined according to the type of character selected by the player at the start of the big bonus. When it is determined that RT navigation is to be performed, RT navigation notification is performed in a different manner depending on the type of character selected by the player at the start of the big bonus, and at a different timing. On the other hand, only the RT navigation notification mode differs according to the type of character selected by the player, or only the timing for performing the RT navigation notification depends on the character type selected by the player. You can also.

  In addition, it is determined whether or not to be executed at different triggers according to the player's selection, and the process to be notified at different modes and timings is not limited to RT navigation. For example, in addition to the regular bonus and big bonus game states, the game state controlled on the side of the game control board 101 is only the normal game state, and directing in a predetermined period after the big bonus according to the lottery performed during the big bonus In a slot machine that executes AT (Assist Time) that announces the small role winning on the control board 102 side, the decision as to whether or not to execute AT is executed at different timings according to the player's choice, with different modes and timing It is good also as what notifies. In addition, it is determined whether or not to be executed at different triggers according to the player's selection, and the process to be notified at different modes and timings is a process determined on the game control board 101 side. May be.

  In the above embodiment, only the big bonus of the regular bonus and the big bonus is selected by the player's operation by selecting the type of character (effect mode) executed during the big bonus at the start of the bonus. Whether or not to perform RT navigation is determined in accordance with the type of RT navigation, and RT navigation notification is performed. However, these things can be performed not only in the big bonus but also in the regular bonus, and can be performed only in the regular bonus without being performed in the big bonus.

  In the embodiment described above, when the setting key switch 92 is turned on without starting the first reset switch 48 or the second reset switch 93 and the slot machine 12 is started and the setting value is changed. The RAM 112 is not initialized at all except that a new set value is stored. For this reason, even in a game after a setting value change operation has been performed, the game value and the winning flag setting status (regular bonus, big bonus (1) or big bonus (2) win) The game was carried over from the previous game.

  On the other hand, in the game after the setting value changing operation, the gaming state is carried over from the game before the setting value changing operation, but the winning flag setting status is before the setting value changing operation. It is good even if it is not carried over from the game of. This is because, for example, an area for storing data such as a gaming state in the RAM 112 and an area for setting a winning flag are separated, and the setting key is set without turning the first reset switch 48 or the second reset switch 93 on. When the slot machine 12 is activated with the switch 92 turned on, the former area is not initialized, but the latter area is initialized.

  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 number of bets in the normal gaming state, RT1, RT2 or RT3, the winning probability of the small role in the internal lottery is lower than when 3 is set as the number of bets. It is possible to increase the number of medals to be paid out when winning a small role.

  In the above embodiment, in a game in which the gaming state is the big bonus and the big bonus medium flag is set in the RAM 112, it is determined whether or not the regular bonus medium flag is set in the RAM 112 when the start lever 11 is operated. If the regular bonus medium flag is not set, this is set to control the regular bonus. Thus, even when the regular bonus is controlled first after the big bonus (1) or big bonus (2) is won, the regular bonus is controlled again when the regular bonus for one time has ended and the big bonus has not yet ended. Even in this case, the same processing should be performed.

  On the other hand, when the big bonus (1) or the big bonus (2) is won, a regular bonus medium flag is set in the RAM 112 together with the big bonus medium flag, and when the regular bonus end condition is established in the big bonus, Clear regular bonus medium flag. Here, when the regular bonus medium flag is deleted, if it is determined that the big bonus end condition is not satisfied and the big bonus medium flag is set in the RAM 112, the regular bonus medium is again set. The flag may be set in the RAM 112 and controlled to a new regular bonus as it is. In this case, when the big bonus is controlled by winning the big bonus (1) or the big bonus (2), it can be controlled to the regular bonus at the same time. When the bonus is not finished, you can immediately return to the regular bonus.

  The gaming state of the big bonus provides a small role game by winning the big bonus (1) or the big bonus (2), and further, JACIN (for example, “Bell-JAC-” based on JACIN winning in the small role game. It is also possible to provide a regular bonus among the big bonuses in the gaming state by winning a prize in an internal lottery during a small role game in “JAC”.

  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.
