Description

  The present invention relates to a slot machine, particularly when it is determined that the derivation of the special display result is permitted, and when it is determined that the derivation of the priority display result among the winning display results other than the special display result is permitted. Further, the present invention relates to a slot machine for deriving a priority display result that is determined to be permitted to be derived regardless of the operation procedure of the stop operation means.

  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.

  In general, in order to receive a winning combination for each role including a bonus role with a transition to a gaming state advantageous to the player (big bonus, regular bonus, etc.) The winning flag must be set by winning the internal lottery. However, since the winning probability of each role in the internal lottery is uniquely determined according to the set value, if the presence or absence of winning of the bonus role depends only on the result of the internal lottery, The wave of the game state of whether the game state is changed in an advantageous game state or an unfavorable game state becomes simple.

  Therefore, in addition to stocking bonus winnings, when one or more bonus winnings are stocked, the gaming state is controlled to RT (a gaming state in which the replay winning probability is higher than usual) for a predetermined period of time, and the RT is played. While the state is being controlled, bonus winnings will not be awarded even if the bonus winning stock is stocked. Then, by changing the period during which the gaming state is controlled by RT, the gaming state in which transition is made between a gaming state advantageous to the player and an unfavorable gaming state without depending only on the result of the internal lottery (For example, refer to Patent Document 1).

JP 2003-180946 A (paragraphs 0036 to 0041)

  However, in the slot machine of Patent Document 1, if the player is replayed with the result of the internal lottery while the RT is controlled to prevent the bonus winning, the replay winning occurs frequently and the bonus Even if not so, RT becomes a gaming state advantageous to the player. If the RT itself becomes a game state advantageous to the player, the game state advantageous to the player will continue too much, and it also means that it is impossible to win a bonus by controlling the RT. It becomes something without.

  Therefore, in the slot machine disclosed in Patent Document 1, in the RT where the winning is impossible even if the bonus winning is stocked, the reel is controlled so that the player cannot forcibly win even if winning the replay. It was assumed that the game state would not be advantageous to the player. However, in spite of the fact that there is a winning combination (in this case, bonus and replay) in this way, it is a factor that causes dissatisfaction for the player to be unable to win any of them. It was.

  Further, in the slot machine of Patent Document 1, there are different types of bonus combinations, that is, a big bonus and a regular bonus, but only the game state of the bonus controlled depending on which combination is won is changed. . The player was not interested in which type of bonus combination was won until after the gaming state of the bonus based on winning of the bonus combination ended.

  The present invention prevents the player from being dissatisfied with any of the winning display results determined to allow derivation, and the player's interest in the type of the special display result thus derived. An object of the present invention is to provide a slot machine capable of increasing the height.

To achieve the above object, a slot machine according to the present invention includes:
A variable display device that allows a game to be started by setting a predetermined number of bets for one game using a gaming value (medal), and displays a plurality of types of identification information that can be distinguished from each other in a variable manner. In the slot machine (slot machine 1) in which one game is completed by the display result being derived to the (variable display device 2) and a winning can be generated according to the display result derived to the variable display device.
Before a display result is derived to the variable display device for each game, a special display result (big bonus (1), big bonus (2) accompanied by a transition to a special gaming state (big bonus) advantageous to the player) ), A big bonus (3)), a replay display result (replay) accompanied by a replay that allows the next game to be executed without using the game value for setting the bet number, and the bet number Multiple types of winnings including a minority payout result (one winning combination A, one winning combination B, one winning combination C, one winning combination D) with payout of a smaller number of game values than required for setting Pre-determining means (CPU 111 of the game control board 101 (FIG. 6)) for determining whether or not to allow the derivation of the display result;
Stop operation means (stop buttons 12L, 12C, 12R) operated by the player to stop the variation display of the identification information;
Derivation control means (CPU 111 of the game control board 101) for causing the variable display device to derive a display result in accordance with the determination result of the prior determination means and the operation procedure of the stop operation means;
When it is determined that the derivation of the special display result is permitted, and the special display result is not derived based on the determination, the special determination carry-over means (CPU 111 (Big Bonus (1), Big Bonus (2), Big Bonus (3) winning flags carry over until winning))),
Special gaming state control means (CPU 111 (FIG. 5) of the gaming control board 101) for controlling the gaming state to the special gaming state until a predetermined special ending condition is satisfied when the special display result is derived;
After the special gaming state is over, the player is paid out when a winning display result determined to allow derivation by the pre-determining means for the number of gaming values used for setting the bet amount is derived. Specific game state control means (CPU 111 of game control board 101) for controlling to a specific game state (RT1, RT2, RT3) in which the payout rate calculated by the ratio of the expected value of the number of game values to be played is smaller than 1 (FIG. 5))
The derivation control means is determined to allow the derivation of the special display result, and the priority display result including the replay display result and the minority pay display result among the winning display results other than the special display result. When it is determined that the derivation is permitted, the priority display result determined to permit the derivation is derived regardless of the operation procedure of the stop operation means (big bonus (1), big bonus When winning a single winning combination A or bell together with bonus (2) or big bonus (3), win a single winning combination A or bell regardless of the operating procedure of the stop buttons 12L, 12C, 12R. (1) When the single bonus combination BD is won together with the big bonus (2) or the big bonus (3), the operation procedure of the stop buttons 12L, 12C, 12R is involved. Win one of the one-piece combination B, one-piece combination C or one-piece combination D. Stop button when replaying with big bonus (1), big bonus (2) or big bonus (3) Regardless of the operation procedure of 12L, 12C, 12R, winning a replay)
The specific gaming state control means includes
After the special gaming state controlled based on the derivation of the first special display result (big bonus (1)) of the special display results, the predetermination means allows the re-game display result to be derived. The first specific gaming state control for controlling to the first specific gaming state (RT1) in which the probability that the derivation of the priority display result is not permitted is determined to be a predetermined first probability by determining to the effect Means (CPU 111 (FIG. 5) of game control board 101);
After the special gaming state controlled based on the derivation of the second special display result (big bonus (3)) different from the first special display result among the special display results, the prior determination means A second probability that the probability that the derivation of the priority display result is not determined by determining that the derivation of the replay display result is permitted is lower than the predetermined probability is higher than the first probability. Therefore, the second specific gaming state (RT3) in which the number of games required to derive the special display result after it is determined that the special display result is allowed to be derived is less than the first specific gaming state. And a second specific game state control means (CPU 111 of the game control board 101 (FIG. 5)) for controlling the slot machine.

  In the above slot machine, it is determined by the pre-determining means that the derivation of a plurality of types of winning display results including the special display result, the replay display result, and the minority payment display result is permitted, but the special display result may be derived. When it is determined to do so, the determination is carried over after the next game until a special display result is derived based on the determination. Here, for example, by deciding to allow derivation of special display results such as replay display results and minority payment display results in a state where the decision to allow derivation of special display results is carried over, etc. There is a case where it is determined that the derivation of the special display result is permitted and the derivation of the winning display result other than the special display result is determined.

  Here, it is determined that the derivation of the special display result is permitted, and it is determined that the derivation of the priority display result including the re-game display result and the minority payment display result as the winning display result other than the special display result is determined. Sometimes, the priority display result determined to allow derivation is derived regardless of the operating procedure of the stop operation means by the player, and the special display result is not derived. When it is determined that the derivation of the special display result is permitted and it is not determined that the derivation of the priority display result is permitted, the special display result is derived according to the operation procedure of the stop operation means by the player. Is possible.

  In this way, when it is controlled to a specific gaming state, if it is determined that the derivation of the priority display result is permitted, the special display result cannot be derived even if the special display result cannot be derived. Therefore, the priority display result that has been determined to permit derivation cannot be derived. Accordingly, it is possible to prevent any of the winning display results determined to permit derivation from being derived and to cause dissatisfaction with the player.

  By the way, after the special display result is derived and the special gaming state controlled based on the result is finished, the gaming state is controlled to the specific gaming state. This particular gaming state is because the number of gaming values to be paid out to the player, especially when the result of the minority payment display is derived, is less than the number of gaming values required for setting the betting number. Calculated by the ratio of the expected value of the number of game values to be paid out when the winning display result determined to be allowed to be derived by the pre-determining means for the number of game values used for setting the number is derived The payout rate is smaller than 1. Therefore, when the game state is controlled to a specific game state, it is advantageous for the player to derive the special display result as soon as possible.

  The specific game state includes a first specific game state controlled after the end of the special game state controlled based on the derivation of the first special display result, and a special game controlled based on the derivation of the second special display result. There is a second specific gaming state that is controlled after the end of the state, but in the second specific gaming state, priority display is made by determining that the re-game display result is allowed to be derived with a lower probability than the first specific gaming state. The probability that it is not determined that the derivation of the result is permitted is a second probability higher than the first probability in the first specific gaming state.

In other words, even if controlled in the same special game state, to derive towards the second specific game state that is controlled in the derivation of the second special display results after completion of the based rather special game state is the first special display result in the first small number of games than a specific game state that is controlled after the special game state rather groups Dzu ends (number of games until the effect to allow the derivation of the special display result is determined even is not changed), new The special display result can be derived.

  Thereby, even if controlled to the same special gaming state, it is possible to make the player interested in which of the first special display result and the second special display result is derived as the special display result. it can. In addition, which of the first special display result and the second special display result is derived affects the number of games until the next special display result is derived in the specific gaming state controlled after the end of the special gaming state. Therefore, the player's interest is also extended over a long period of time, and the player's interest in which of the first special display result and the second special display result is derived is increased. Can do.

The slot machine is
When it is controlled to the specific gaming state, it is determined that the derivation of the second special display result is permitted, and when it is not determined that the derivation of the priority display result is permitted, the specific effect Specific effect execution means (CPU 121 of the effect control board 102 (step S105)) for executing (special effect) can be further provided.

  In this case, a specific effect is executed in a game in which it is possible to derive the second special display result accompanied by the transition to the second specific game state that is relatively advantageous to the player in the specific game state. Thus, if the player appropriately operates the stop operation means, the second special display result can be surely derived. Thereby, when it is determined that the second special display result is allowed to be derived, only the specific game state after the special game state controlled by the second special display result being derived based on the determination is determined. Instead, the specific game state before the special game state controlled by deriving the second special display result based on the determination can be ended with a small number of games. Thereby, even if it is determined that the derivation of the second special display result is permitted among the special display results, it is possible to further increase the profit of the player, and further improve the interest of the game. .

In the above slot machine,
The pre-decision means determines non-priority special determination means (FIG. 6: Big Bonus (1), which determines that the derivation of the special display result is allowed without determining that the derivation of the priority display result is allowed). Big bonus (2), big bonus (3)) can be included.

  In this case, in a game in which it is determined that the derivation of the special display result is permitted, the special display result cannot be derived regardless of the operation procedure of the stop operation means due to the derivation of the priority display result. It is also possible to immediately derive the special display result and control the gaming state to the special gaming state. In this way, it may be determined that the derivation of the special display result is allowed without deciding that the derivation of the priority display result is allowed, so that the derivation of the special display result is allowed until the previous game. Even in a case where it is considered that the game has not been decided, it is possible to give the player a sense of expectation for the derivation of the special display result, and the interest of the game can be improved.

In this case,
The pre-decision means decides that the derivation of the priority display result is allowed, and at the same time, the priority special decision means decides that the derivation of the special display result is allowed (FIG. 6: Big bonus (1) +1) B to D, big bonus (2) +1 sheet combination B to D, big bonus (3) +1 sheet combination B to D) may be further included.

here,
The probability that the second special display result is allowed to be derived by the non-priority special determination unit is determined at the same time that the priority special determination unit determines that the priority display result is derived. 2 The probability that it is determined that the derivation of the special display result is permitted may be higher (FIG. 6: the number of determination values of the big bonus (3) is 200, the big bonus (3) +1 role B˜ The number of judgment values for D is 18).

  In this case, in a game in which it is determined that the second special display result is permitted to be derived, this is often derived. Therefore, the second special display is performed while the number of digested games from the end of the special game state is relatively small. The display result can be derived, and the game state can be controlled to the special game state and the second specific game state. When controlled to the second specific gaming state, a special display result can be newly derived and controlled to the special gaming state with a relatively small number of digested games from the end of the special gaming state. By this chain, it is possible to cause a special gaming state advantageous to the player to be repeatedly controlled within a short period of time, and to increase the player's expectation and improve the interest of the game. it can.

Or
The probability that the second special display result is allowed to be derived by the non-priority special determination unit is determined at the same time that the priority special determination unit determines that the priority display result is derived. 2 It may be lower than the probability that it is determined that the derivation of the special display result is permitted (FIG. 10: Big bonus (3) has 18 judgment values, big bonus (3) +1 role B˜ The number of judgment values for D is 200).

  In this case, in a game in which it is determined that the second special display result is allowed to be derived, this is rarely derived, so that the number of digested games after the special gaming state ends increases (approximately during this period) If it is determined that the derivation of the special display result is permitted, the priority display result can be expected to be the second special display result. As a result, even if the number of games that have been digested without a special display result being derived after the special gaming state has ended, the interest of the game can be improved without discouraging the player. it can.

The slot machine is
Predetermined effect execution means (CPU 121 of the effect control board 102 (step S110)) that executes a predetermined effect (notice effect) in different execution states depending on whether or not the derivation of the special display result is permitted. ).

  In a game that is determined to allow the derivation of the priority display result, the special display result is not derived, but even if the game is not determined to permit the derivation of the priority display result, If it has not been determined before that the derivation of the special display result is permitted, the special display result is not derived in the first place. Thus, even if the special display result cannot be derived by executing the predetermined effect in different execution states depending on whether or not it is determined that the derivation of the special display result is permitted, It can be expected that it is determined that the derivation of the special display result is permitted due to the difference in the execution state of the effects, and the entertainment of the game can be improved.

In the above slot machine,
The variable display device includes a plurality of variable display portions, and at least one winning line passing through the plurality of variable display portions is set (the variable display device 2 includes an upper stage, a middle stage, a lower stage, and two diagonal lines. Winning line is set),
The plurality of types of winning display results may be determined for each winning display result by a combination of identification information derived to the plurality of variable display units on the winning line (FIG. 4: each combination) The symbol combination). here,
The minority payment display result includes a specific minority payment display result in which the identification information in the specific variable display unit of the plurality of variable display units is common with the identification information in the specific variable display unit in the combination of the special display result Case (FIG. 4: Big Bonus (1) is “Red 7-Red 7-Red 7”, Big Bonus (2) is “Blue 7-Blue 7-Blue 7”, and Big Bonus (3) is “White 7-White” 7-White 7 ", 1st part B is" Red 7-Bell-Bell ", 1st part C is" Blue 7-Bell-Bell " ,
The slot machine is determined to allow derivation of the special display result when the predetermination means determines that the special display result or the specific minority payment display result is derived. It is possible to further include an suggestion effect execution means for executing the suggestion effect (sound effect) that suggests (CPU 121 of the effect control board 102 (step S109)).

  Here, since the specified minority payout display result is included in the priority display result, when it is determined that the derivation is permitted, the special display result cannot be derived anyway. . However, since the identification information in the specific variable display unit is common to the identification information in the specific variable display unit in the combination of the special display results, the identification information is derived only in the specific variable display unit. At this stage, the player can still be expected to derive the special display result. Thus, even when the identification information is derived to some of the variable display portions (specific variable display portions), it is possible to improve the interest of the game by still giving the player a sense of expectation.

  The power supply board 100 sets a winning probability for an internal lottery to be described later, and a setting switch 91 for changing a setting value (setting 1 to setting 6) of a virtual medal payout rate calculated based on the probability. The switch 91 is also connected to a setting key switch 92 for enabling the operation, a second reset switch 93 for resetting the internal state (RAM 112), and a main switch 94 for switching the power ON / OFF. A signal is sent to the game control board 101. These switches 91 to 94 are provided inside the slot machine 1.

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

  The CPU 111 has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, and executes a program (described later) stored in the ROM 113 to perform processing related to the progress of the game, and in the slot machine 1 Control each part of the control circuit directly or indirectly. The processing word of the CPU 111 is 1 byte, and the addresses of the RAM 112 and the ROM 113 are assigned in units of 1 byte.

  The RAM 112 is used as a work area when the CPU 111 executes a program. The RAM 112 is backed up by a battery and retains stored contents even when the slot machine 1 is turned off. The RAM 112 is provided with an area for a counter that counts the number of steps of the stepping motors that respectively constitute the reel motors 3ML, 3MC, and 3MR. Data relating to the number of credits is stored in the RAM 112. The ROM 113 stores programs executed by the CPU 111 and fixed data. The I / O port 114 inputs and outputs control signals to and from each circuit connected to the game control board 101.

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

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

  The reset circuit 118 outputs a reset signal to start the control unit 110 when the voltage rises to a level at which the control unit 110 can be activated when the power is turned on, 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 be described later 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.

  The command transmitted from the game control board 101 to the effect control board 102 is composed of 2 bytes, the upper 1 byte is control information indicating the type of command, and the lower 1 byte is information indicating the contents of the control state. When transmitting a command from the game control board 101 to the effect control board 102, the CPU 111 sets a command to be transmitted in a command transmission buffer provided in the RAM 112 in the order of upper byte and lower byte.

  Since the CPU 111 needs to transmit a plurality of commands to the effect control board 102 at the same time in some cases, the command transmission buffer of the RAM 112 has a capacity sufficient to set a predetermined number of commands. For example, when two commands are transmitted at the same time, the upper byte and lower byte of the first command, the upper byte and lower byte of the second command, etc. are set in the command transmission buffer of the RAM 112. The upper byte and lower byte of each command set in the command transmission buffer are sent from the I / O port 114 to the effect control board 102 in byte units.

  The game control board 101 is provided with a single BET switch 45, a MAXBET switch 46, a start switch 41, stop switches 42L, 42C, 42R, a checkout switch 47, a first reset switch 48, and a throw-in medal through the operation unit relay board 107. A sensor 44 is connected, and detection signals from these 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 is also provided with a flow path switching solenoid 49, a payout number display 51, a credit display 52, a payout display 53, an insertion instruction lamp 59, and a single betting lamp 54 via the operation unit relay board 107. 2 bet lamp 55, 3 bet lamp 57, game over lamp 63, start lamp 60, replay lamp 62, BET button lamps 70a and 70b, operation valid lamps 63L, 63C and 63R are connected, and CPU 111 These operations are controlled according to the progress of the game.

  The game control board 101 is connected to reel motors 3ML, 3MC, and 3MR via a reel relay board 103. The CPU 111 refers to a stop control table selected according to a winning flag set in the RAM 112 by internal lottery, which will be described later, and controls the reel motors 3ML, 3MC, 3MR via the reel relay board 103 to thereby control the reels 3L, 3C. 3R is stopped. 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 RAM 122 is used as a work area when the CPU 121 executes a program. The RAM 122 is also battery-backed up, and retains the stored contents even when the slot machine 1 is turned off. The ROM 123 stores programs executed by the CPU 121 and fixed data. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

  The execution of the effect by the CPU 121 is performed based on a command received from the game control board 101 via the I / O port 124. When a command transmitted from the game control board 101 arrives at the I / O port 124, a command reception interrupt is generated for the CPU 121, and the received command is sequentially placed in the command reception buffer of the RAM 122 by this command reception interrupt processing. To go. The CPU 121 retrieves the command stored in the command reception buffer in units of 2 bytes, and performs processing by determining the command type in the upper byte and the content indicated by the command in the lower byte.

  When a plurality of commands are transmitted from the game control board 101 at the same time, the CPU 121 cannot naturally process the plurality of commands at the same time. For this reason, the command reception buffer of the RAM 122 has a capacity enough to store a plurality of commands, and the CPU 121 has received another command when processing based on one command extracted from the command reception buffer is completed. If it is in the buffer, the processing based on the next command is performed. Note that the capacity of the command reception buffer in the RAM 122 is larger than the capacity of the command transmission buffer in the RAM 112.

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

  The reel relay board 103 relays between the game control board 101, the external output board 105 and the reel unit 3. The reel lamp relay board 104 relays between the effect control board 102 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.

  When a full tank is detected by the full tank sensor 90, a full tank error occurs. Note that whether or not a full tank is detected by the full sensor 90 can be checked once per game, for example, at a timing when the number of bets is fixed. However, when the player has won a replay in the previous game, it is not checked whether the full sensor is detected by the full sensor 90.

  The external output board 105 is connected to an external device such as a hall management computer via an information providing terminal board, and various bonus medium signals and medals IN input from the game control board 101 via the reel relay board 103. The signal, medal OUT signal, and security signal are output to the external device. The security signal includes a door opening signal, a set value change signal, a closing error signal, a payout error signal, another error signal, and a checkout signal.

  Next, stepping motors constituting the reel motors 3ML, 3MC, 3MR will be described. The stepping motor that constitutes each of the reel motors 3ML, 3MC, and 3MR is, for example, a hybrid type stepping motor, and includes a stator and a rotor facing the stator. The rotor has a large number of gear-like projections, and permanent magnets magnetized in the same direction as the rotation shaft are incorporated therein.

  The stepping motor receives a pulse signal (excitation pulse) from the CPU 111 of the game control board 101, an excitation current sequentially flows through each of the excitation phases φ1 to φ4 of the stator, and these excitation phases φ1 to φ4 are excited in a predetermined order. Thus, the rotor is rotationally driven, and the reels 3L, 3C, and 3R are rotated by the rotation of the rotation shaft. As a control method for rotationally driving the stepping motor, for example, a 1-2 phase excitation method is applied. In the 1-2 phase excitation method, the excitation phases for inputting a pulse signal among the excitation phases φ1 to φ4 are (φ1, φ2), (φ1), (φ4, φ1), (φ4), (φ3, φ4), (Φ3), (φ2, φ3), (φ2), (φ1, φ2)... Are sequentially switched, and the excitation phase for inputting the pulse signal is alternately switched to one phase or two phases. Yes.

  Thus, each time a pulse signal for applying an excitation current to the excitation phases φ1 to φ4 is input, the rotation shaft of the stepping motor rotates one step at a time. The rotation step of the stepping motor is counted by a counter provided in the RAM 112 for each of the reel motors 3ML, 3MC, and 3MR. Then, it is understood how to switch the excitation phase of the pulse signal input according to the counted stepping motor rotation step.

  Further, when the reference position is detected by the reel sensors 3SL, 3SC, 3SR as the reels 3L, 3C, 3R rotate, the counter value is cleared. Therefore, the rotation angles of the reel motors 3ML, 3MC, and 3MR, that is, the symbol positions of the reels 3L, 3C, and 3R can be understood by referring to the counter value (number of steps) counted by the rotation step.

  When stopping the rotation of the stepping motor, the rotor is suddenly braked by two-phase excitation control, which will be described in detail later, in accordance with the target stop position, and then the rotor is stopped by three-phase excitation control, which will be described later. This stops the rotation of the reels 3L, 3C, and 3R that are integrally coupled to the rotors of the reel motors 3ML, 3MC, and 3MR.

  Next, changing the set value will be described. When the slot machine 1 is activated with the setting key switch 92 turned ON, the mode shifts to the setting change mode. Here, the number of steps of the stepping motors constituting the reel motors 3ML, 3MC, and 3MR in the storage area of the RAM 112 is counted. Initialize all storage areas except the counter and the used stack area. In the setting change mode, when a new setting value is set by the setting switch 91 and the setting key switch 92 is turned off after the new setting value is confirmed by operating the start lever 11, a process for executing the game is performed. Can be started.

  On the other hand, when the slot machine 1 is started with the setting key switch 92 turned OFF, it is diagnosed whether the data in the RAM 112 is corrupted. If the data in the RAM 112 is not corrupted, that is, the power of the previous slot machine 1 is turned on. If the data at the time of turning off remains normal, the data stored in the RAM 112 is left as it is, and the process for executing the game from the state when the power of the slot machine 1 was turned off last time Can be started. The process for executing the game is repeatedly performed for each game.

  Next, the symbol arrangement in the reels 3L, 3C, 3R constituting the variable display device 2 will be described. FIG. 3 is a diagram showing a symbol arrangement on the reels 3L, 3C, 3R. As shown in the drawing, on the outer peripheral portions of the reels 3L, 3C, and 3R, “red 7” (7 indicated by black in the drawing) and “blue 7” (7 indicated by diagonal lines in the drawing), respectively. ), "White 7" (7 shown in white in the figure), "Watermelon", "Bell", "Cherry", "JAC", "★" Each 21 is drawn in a predetermined order.

  For the convenience of the drawings, these symbols are shown vertically arranged for each of the reels 3L, 3C, and 3R, but are actually drawn on the outer periphery of the cylindrical reels 3L, 3C, and 3R. Therefore, the symbol arrangement is circulated, and the symbol No. 20 and the symbol No. 0 are adjacent to each other. Further, for example, a symbol in a position where four frames are drawn from a symbol of No. 20 is a symbol of No. 3.

  As shown in the figure, only one “red 7”, “blue 7”, and “white 7” are arranged for each of the middle and right reels 3C and 3R. Two “red 7”, “blue 7”, and “white 7” are arranged on the left reel 3L. If only “Red 7”, “Blue 7”, or “White 7” is viewed, there are places where the interval is 5 frames or more, but “Red 7”, “Blue 7”, “White 7” In any case, the arrangement interval is within 5 frames. In addition, for any of the reels 3L, 3C, and 3R, “bell” and “JAC” are arranged at intervals of 5 frames or less. On the other hand, as for “watermelon”, there is a place where the arrangement interval is 5 frames or more in any of the reels 3L, 3C, and 3R. For the right reel 3R, only two “cherries” are arranged.

  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 game states controlled by the CPU 111 of the game control board 101 include a big bonus as a special game state and RT1, RT2, and RT3 as game states other than the special game state. As will be described in detail later, RT1, RT2, and RT3 have different replay winning probabilities from each other, but the winning probabilities of the other roles are the same. The game state transition will be described in detail later.

  In addition, the types of winning combinations are broadly divided into special roles (Big Bonus (1), Big Bonus (2), Big Bonus (3)) that shift to the special gaming state, and medal payout. There are accompanying small roles (bell, watermelon, cherry, one-piece roles AD), and a replaying role (replay) that allows the next game to be started without the need to set the number of bets. FIG. 4 is a view for explaining the combination of the types of winning combinations in the slot machine 1 and the symbols in the variable display device 2.

  The big bonus (1) is won when a combination of “red 7-red 7-red 7” is arranged on any winning line in a gaming state other than the big bonus. The big bonus (2) is won when a combination of “blue 7-blue 7-blue 7” is arranged in any winning line in a gaming state other than the big bonus. The big bonus (3) is won when a combination of “white 7-white 7-white 7” is arranged in any winning line in a gaming state other than the big bonus. When the big bonus (1), the big bonus (2) or the big bonus (3) is won, the gaming state shifts to the big bonus.

  In the big bonus, the regular bonus is repeatedly offered until the number of medals paid out exceeds 390 (whether the regular bonus is controlled at the start of each game in the big bonus (before the internal lottery)) Check and control to regular bonus if not controlled to regular bonus). One set of regular bonuses controlled during the big bonus ends when 12 games are consumed or when 8 games are won (any kind of combination is acceptable), whichever comes first.

  After the big bonus is over, the gaming state is controlled to either RT1, RT2 or RT3. Which of RT1, RT2, and RT3 is controlled depends on which of the big bonus (1), big bonus (2), and big bonus (3) triggered the control of the gaming state by the previous big bonus. If it is a big bonus (1), it is controlled to RT1, if it is a big bonus (2), it is controlled to RT2, and if it is a big bonus (3), it is controlled to RT3.

  Even if the big bonus (1), the big bonus (2), or the big bonus (3) is won in the internal lottery described later, “red 7”, “blue 7”, “white 7” are not necessarily reels 3L, Since it is not arranged at intervals of 7 frames for 3R and 5 frames for reel 3C, the operation procedure of stop buttons 12L, 12C, 12R (meaning including both the operation order and operation timing. The same) may not win these roles. However, the big bonus (1), big bonus (2) or big bonus (3) wins are carried over until winning.

  In addition, when winning a big bonus (1), a big bonus (2) or a big bonus (3) and winning another winning combination, the winning of the other winning combination is given priority. You may not win these roles. In particular, when the player also wins a bell, a single winning combination A or a replay, or when a single winning combination B to D is simultaneously selected, the big bonus regardless of the operation procedure of the stop buttons 12L, 12C, 12R. (1) Don't win big bonus (2) or big bonus (3). In other words, to win the big bonus (1), big bonus (2), or big bonus (3), these roles are won, and the bell, the single role A, the replay win or the single role BD The condition that there is no simultaneous winning of is required.

  A bell is awarded when a combination of “bell-bell-bell” is arranged on any winning line in any gaming state, and 15 medals are paid out (that is, a player's Medals (including credits, the same applies hereinafter)). Since all of the reels 3L, 3C, 3R are arranged at intervals of 5 frames or less, if a bell is won in the internal lottery, a prize is always won. Even if the winning of the big bonus (1), the big bonus (2) or the big bonus (3) is carried over, the winning of the bell is given priority as will be described later. ), Be sure to win the bell without winning the big bonus (2) or big bonus (3).

  A watermelon is awarded when a combination of “watermelon-watermelon-watermelon” is aligned on any winning line in any gaming state, and 5 medals are paid out (that is, the player's More medals). Since the “watermelons” are not necessarily arranged at intervals of 5 frames or less for any of the reels 3L, 3C, 3R, even if the watermelon is won in the internal lottery, the stop buttons 12L, 12C, 12R Depending on the operation procedure, there may be no winning.

  If you win a watermelon when the Big Bonus (1), Big Bonus (2), or Big Bonus (3) is being carried over, the watermelon win will be given priority as will be described later. If the operation procedure of 12L, 12C, 12R is an operation procedure that allows a watermelon to win (if it is a big bonus (1), an operation procedure that can also win a big bonus (2) or a big bonus (3)) Even if it is). The stop buttons 12L, 12C, and 12R are operated in an operation procedure that can be awarded to the big bonus (1), the big bonus (2), or the big bonus (3) among the operation procedures that cannot be awarded to the watermelon. Only when it is made, the player may win the big bonus (1), the big bonus (2), or the big bonus (3). In addition, the winning of watermelon, which is a small role, will not be carried over without winning a prize.

  Cherry is awarded when the symbol “Cherry” is derived on any winning line for the right reel 3R in any gaming state, and two medals are paid out per winning line. When “Cherry” is stopped at the upper or lower tier of the right reel 3R (the cherry win is always the upper or lower tier), it will always be a two-line win, so a total of four medals It will be paid out (that is, the player's cherries are increased by winning the cherries).

If you win the cherry when the big bonus (1), big bonus (2), or big bonus (3) wins are carried over, the cherry win will be given priority as will be described later. If the operation procedure of 12L, 12C, and 12R is an operation procedure that allows the cherry to win (if the big bonus (1), the operation procedure that can also win the big bonus (2) or the big bonus (3) Even if it is). The stop buttons 12L, 12C, and 12R are operated in the operation procedure that can be awarded to the big bonus (1), the big bonus (2), or the big bonus (3) among the operation procedures that cannot be awarded to the cherry. Only when it is made, the player may win the big bonus (1), the big bonus (2), or the big bonus (3). In addition,
The winning of Cherry, a small role, will not be carried over without winning a prize.

  A single winning combination A becomes a prize when a combination of “JAC-Bell-Bell” is aligned on any winning line in any gaming state, and a single medal is paid out (that is, the single winning combination A Winners will reduce the player's medals.) “JAC” for the reel 3L and “Bell” for the reels 3C and 3R are arranged at intervals of 5 frames or less. Even if the winning combination of the single bonus A is won when the winning of the big bonus (1), big bonus (2) or big bonus (3) is carried over, the winning of the single bonus A is given priority as will be described later. Therefore, the single bonus A is always won without winning the big bonus (1), big bonus (2) or big bonus (3).

  A single winning combination B becomes a winning combination when a combination of “red 7-bell-bell” is aligned on any winning line in any gaming state, and a single medal is paid out (that is, a single winning combination B). Will reduce the player's medal.) A single winning combination C becomes a winning combination when a combination of “blue 7-bell-bell” is aligned on any winning line in any gaming state, and a single medal is paid out (that is, a single winning combination C). Will reduce the player's medal.) A single winning combination D is awarded when a combination of “white 7-bell-bell” is aligned on any winning line in any gaming state, and a single medal is paid out (that is, a single winning combination D). Will reduce the player's medal.)

  As will be described later, three of the single-player roles B to D are always won simultaneously as a set (however, the big bonus (1), the big bonus (2), or the big bonus (3) may be won simultaneously) ), Only one or two of them will not win. The “bells” for the reels 3C and 3R are arranged at intervals of 5 frames or less. The reel 3L is also arranged at intervals of 5 frames or less as long as it is any one of “red 7”, “blue 7”, and “white 7”.

  For this reason, if one winning combination B to D is won simultaneously in the internal lottery, any one winning combination B to D is always won. When the big bonus (1), big bonus (2), or big bonus (3) wins are carried over, and when one winning combination BD is won simultaneously, or the big bonus (1), big bonus (2) Alternatively, even when the single bonus combination B to D is simultaneously won together with the big bonus (3), the winning of the single bonus combination B to D is given priority as will be described later, so the big bonus (1), big bonus (2) or The big bonus (3) is always won in any one of the combinations BD without winning.

  Replay is awarded when a combination of “JAC-JAC-JAC” is aligned on any winning line at RT1, RT2 or RT3. When a replay is won, the medal is not paid out, but the next game can be started again without setting the number of bets (that is, the player's medal is not increased or decreased by the replay winning). Since all of the reels 3L, 3C, and 3R are arranged with an interval of 5 frames or less, a win is always awarded if replay is won in the internal lottery. Even if the winning of the big bonus (1), the big bonus (2) or the big bonus (3) is carried over, the winning of the replay is given priority as will be described later. ) Be sure to win the replay without winning the big bonus (2) or big bonus (3).

  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 rotation of the corresponding reels 3L, 3C, and 3R is stopped.

  The rotation of the reels 3L, 3C, 3R is indicated on the winning line with the winning flag set within the range of the maximum stop delay time of 190 milliseconds from the operation of the corresponding stop buttons 12L, 12C, 12R. In addition, it is controlled so that a symbol of a combination for which a winning flag is not set is not aligned on the winning line within a range of a maximum stop delay time of 190 milliseconds.

  In RT1, RT2 or RT3, the replay winning flag is duplicated by winning the replay with the big bonus (1) winning flag, big bonus (2) winning flag or big bonus (3) winning flag carried over. When being played, control is performed so that the replay symbols are preferentially aligned on the winning line. Regardless of the operation procedure of the stop buttons 12L, 12C, and 12R, the replay is won. In this case, the big bonus (1), the big bonus (2), or the big bonus (3) is not won.

  Here, the reason why the big bonus (1), the big bonus (2), or the big bonus (3) is never won by winning in the replay is that the reel 3L is controlled when stop control is performed so that the winning is given priority over the replay. This is because the replay is not missed in the arrangement of “JAC” in 3C and 3R, and the stop control that gives priority to the replay is the stop control that does not miss the replay. is not. Unlike FIG. 3, if the “JAC” symbol interval is larger than 5 frames, the replay may be missed even in the stop control in which the replay is given priority.

  In RT1, RT2 or RT3, the big bonus (1) winning flag, the big bonus (2) winning flag or the big bonus (3) winning the bell by winning the bell or the single-player combination A with the winning flag carried over When the winning flag of the one-player combination A winning flag is also set, the control is performed so that the bell or the single-player combination A is preferentially aligned on the winning line, as in the case of replay.

  In RT1, RT2 or RT3, by winning one of the roles BD with the big bonus (1) winning flag, big bonus (2) winning flag or big bonus (3) winning flag carried over, or Big Bonus (1), Big Bonus (2), Big Bonus (3) and Big Bonus (1) Winning Flag, Big Bonus (2) Winning Flag or Big Bonus (3) When the winning flag and the winning flags of the single winning combination B to D are set to overlap, the winning line is given priority to the symbols of the single winning combination B, the single winning combination C, and the single winning combination D. Controlled to align to the top.

  Here, for example, when the left stop button 12L is operated first, any one of the symbols “red 7”, “blue 7”, and “white 7” is displayed on the left according to the operation timing. The reel 3L is stopped at one of the upper, middle and lower stages. Thereafter, when the middle stop button 12C and the right stop button 12R are operated, any one of “red 7,” “blue 7,” and “white 7” is stopped on the left reel 3L. The symbols of “bells” arranged at intervals of 5 frames or less on the inner reel 3C and the right reel 3R are stopped. In this way, without winning the big bonus (1), the big bonus (2), or the big bonus (3), the player always wins one of the single combination B, the single combination C, or the single combination D.

  When the left stop button 12L is to be operated third, the reels 3C and 3R that have been stopped first are tempered with the “JAC” symbol on any winning line. (“JAC” for the inner reel 3C and the right reel 3R are arranged at intervals of 5 frames or less, so the “bell” tempering state is maintained regardless of the operation procedure of the stop buttons 12C, 12R. Can be). Then, when the left stop button 12L is lastly operated, the symbol "Red 7", "Blue 7", or "White 7" is displayed on the left reel 3L according to the operation timing. Will be stopped on the winning line. In this way, without winning the big bonus (1), the big bonus (2), or the big bonus (3), the player always wins one of the single combination B, the single combination C, or the single combination D.

  Even when the left stop button 12L is operated second, the left stop button 12L is first or third regardless of which one of the stop buttons 12C and 12R is operated first and which is operated third. As in the case of the operation, without winning the big bonus (1), the big bonus (2) or the big bonus (3), either the single winning combination B, the single winning combination C or the single winning combination D You will always win a prize.

  In RT1, RT2 or RT3, the watermelon winning flag is duplicated by winning the watermelon with the big bonus (1) winning flag, big bonus (2) winning flag or big bonus (3) winning flag carried over. When it is set, “watermelon” is controlled with priority on the winning line. Even if “Watermelon” cannot be aligned on any winning line due to the operation procedure of the stop buttons 12L, 12C, 12R, “Red 7”, “Blue 7” or “White 7” is positioned on the winning line. In this case, stop control of the reels 3L, 3C, 3R for winning the big bonus (1), the big bonus (2), or the big bonus (3) can be performed.

  For example, when winning the big bonus (1) and operating the left stop button 12L for the first time, if the operation timing is the timing when the symbols other than No. 13 are located in the lower stage, No. 2, No. 7, Either “12” or “20” “watermelon” can be stopped at the upper, middle or lower stage of the reel 3L, and “red 7” is not stopped at any of the upper, middle and lower stages of the reel 3L. However, if the operation timing of the left stop button 12L is the timing at which the 13th symbol is located in the lower stage, any of the “watermelons” of No. 2, 7, 12, and 20 is in the upper, middle and lower stages of the reel 3L. In any case, the “red 7” of No. 15 and / or 17 can be stopped at the upper, middle, or lower level of the reel 3L.

  In RT1, RT2 or RT3, winning the cherry with the big bonus (1) winning flag, big bonus (2) winning flag or big bonus (3) winning flag carried over will also set the cherry winning flag redundantly When it is set, priority is given to winning the cherry, that is, stopping the “cherry” in the right reel 3R. When “Cherry” cannot be stopped on the right reel 3L and “Red 7”, “Blue 7” or “White 7” can be aligned on the winning line, the big bonus (1), The stop control of the reels 3L, 3C, 3R for winning the big bonus (2) or the big bonus (3) can be performed.

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

  Next, in the slot machine 1 according to this embodiment, the transition of the game state controlled by the CPU 111 of the game control board 101 will be described. FIG. 5 is a transition diagram of game states controlled by the CPU 111 of the game control board 101. As shown in the figure, in the slot machine 1 according to this embodiment, when the big bonus (1), big bonus (2) or big bonus (3) is won at RT1, RT2 or RT3, the gaming state is controlled to the big bonus. Is done.

  When the number of medals paid out to the player in the big bonus exceeds 390, the big bonus ends, but the ended big bonus was controlled when the big bonus (1) was won. In the case of the game, the gaming state is controlled by RT1. When the ended big bonus is controlled when the big bonus (2) is won, the gaming state is controlled by RT2. When the ended big bonus is controlled when the big bonus (3) is won, the gaming state is controlled by RT3.

  When the gaming state is a big bonus, a big bonus medium flag is set in the RAM 112. When in RT1, the flag during RT1 is set in the RAM 112, when in RT2, the flag during RT2 is set in RT3, and when in RT3, the flag during RT3 is set in the RAM 112, respectively. Of course, whether RT1, RT2, or RT3 is controlled depends on whether the big bonus (1), the big bonus (2), or the big bonus (3) is won before the big bonus ends. Therefore, the RT1 flag, the RT2 flag, or the RT3 flag are set when the big bonus (1), the big bonus (2), or the big bonus (3) is won (the RT1 flag, Even if the RT2 in-progress flag or the RT3 in-progress flag is set, the big bonus medium flag is preferentially determined to be in the big bonus game state, and it is not determined to be RT1, RT2 or RT3).

  Hereinafter, the internal lottery will be described. The internal lottery is to determine whether or not the winning of each of the above combinations 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. Of the winning flags set according to the result of the internal lottery, the winning flag for the special role is carried over from the next game until winning. In addition, the winning flags of various small roles and replaying roles are erased only for the game regardless of whether or not a prize has been won.

  FIG. 6 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 the difference in the set value (the set value 1 is the number of determination values among the set values 1 to 6). ), And the set value 6 has the largest number of determination values (however, there are also cases where the same determination value number is used regardless of the set value). In the internal lottery, a plurality of combinations may be subject to lottery at the same time.

  In accordance with this winning state-specific winning combination table, in the internal lottery, big bonus (1), big bonus (1) +1 bonus combination BD, big bonus (2), big bonus (2) +1 bonus combination BD, big Bonus (3), Big Bonus (3) +1 Bonus B to D, Bell, Watermelon, Cherry, Single Bonus A, Single Bonus B to D, and the number of replay judgment values are acquired in order according to the game state The In the winning state-specific winning combination table of FIG. 6, the single combination BD indicates that the single combination B, the single combination C, and the single combination D are simultaneously won (big bonus ( 1) The same applies to the case of simultaneous winning with Big Bonus (2) or Big Bonus (3)).

  However, for the big bonus, the big bonus (1), the big bonus (1) +1 role BD, the big bonus (2), the big bonus (2) +1 role BD, the big bonus (3) , Big Bonus (3) +1 Bonus B to D, and 0 is registered as the number of replay judgment values, and these wins will not be won.

  Also, in the gaming state of RT1, RT2, RT3, depending on whether the big bonus (1), big bonus (2) or big bonus (3) was won in the previous game and the winning flag was carried over Therefore, the number of registered judgment values is different. In a game in which the winning flag of big bonus (1), big bonus (2) or big bonus (3) is not carried over in RT1, RT2, RT3, big bonus (1), big bonus (1) +1 role B ~ A value other than 0 is registered as the number of determination values for D, Big Bonus (2), Big Bonus (2) +1 Bonus B to D, Big Bonus (3), Big Bonus (3) +1 Bonus B to D And may be elected for these roles.

  On the other hand, in a game in which the winning flag of big bonus (1), big bonus (2) or big bonus (3) is carried over in RT1, RT2, RT3, big bonus (1), big bonus (2) or big Since bonus (3) is not won, Big Bonus (1), Big Bonus (1) + 1 Bonus BD, Big Bonus (2), Big Bonus (2) + 1 Bonus BD, Big Bonus (3), 0 is registered as the number of determination values for the big bonus (3) +1 sheet combination B to D, and these combinations will not be won. In addition, as long as 0 is registered as the judgment value number of big bonus (1) +1 sheet combination B to D, big bonus (2) +1 sheet combination B to D, big bonus (3) +1 sheet combination B to D The number of determination values for the single combination B to D is higher than the value in the game in which the winning flag of the big bonus (1), the big bonus (2), or the big bonus (3) is not carried over.

  When the winning of the big bonus (1), big bonus (2), or big bonus (3) is carried over, and you win the bell, watermelon, cherry, single role A, single role BD, replay The winning flags of these combinations are set so as to overlap the winning flags of the big bonus (1), the big bonus (2), or the big bonus (3).

  The number of determination values for each combination will be described. In the big bonus, the number of determination values of the bell is as high as 65531, and the winning of the bell will be won with a probability close to almost 100%. As described above, the bell is a winning combination regardless of the operating procedure of the stop buttons 12L, 12C, and 12R, and in the big bonus, the bell is won with a probability close to 100%. Assuming that all the games in the big bonus win the bell, the number of medals held by the player with one big bonus will increase by 405− (405 ÷ 15) × 3 = 324. .

  Big Bonus (1), Big Bonus (1) +1 Bonus BD in games that have not yet won the Big Bonus (1), Big Bonus (2) or Big Bonus (3) in RT1, RT2, RT3, Big bonus (2), big bonus (2) +1 sheet combination B to D, big bonus (3), big bonus (3) +1 sheet combination B to D are determined in any of RT1, RT2, RT3. Although the values are the same, the total is 654.

  When the big bonus (1), big bonus (2), or big bonus (3) is not won at RT1, RT2, RT3, the big bonus (1), big bonus (2) or big bonus (3 ) (Including the case where a single winning combination B to D is selected as a lottery target combination) is approximately 1 / 100.2. Therefore, it is understood that it takes about 100 games on average from the end of the big bonus until the next winning of the big bonus (1), the big bonus (2) or the big bonus (3) (however, If the setting value is different, the number of these games will be different).

  In addition, each of the big bonus (1), the big bonus (2), and the big bonus (3) may be won by itself or may be simultaneously won by the single roles BD. The big bonus (1) to be controlled by RT1 after the game state of the game is finished is a small number of single winning judgment values as small as 18 (the number of judgment values of simultaneous winning with one player combination B to D is as large as 200) and big The big bonus (3) to be controlled by the RT3 after the bonus gaming state is finished has a large number of single winning determination values as small as 200 (the number of simultaneous winning determination values of one combination B to D is small as 18). ing. In Big Bonus (2), which is controlled by RT2 after the Big Bonus game state ends, the number of determination values for the simultaneous winning of the single winning combination and the single winning combination BD is 109, which is the same.

  By registering such a number of determination values, the big bonus to be transferred to RT3 (which will be the most advantageous for the player among RT1 to RT3 as will be described later) after the gaming state of the big bonus is completed. (3) is a single winning percentage, and after the big bonus game state is over, the big bonus (1) to be transferred to RT1 (which is the most disadvantageous for the player among RT1 to RT3) is the single bonus The winning percentage will be low. In the Big Bonus (2) which is transferred to RT2 (the advantage is intermediate among RT1 to RT3 as will be described later) after the big bonus game state is finished, the probability of the single winning and the simultaneous winning is the same. is there.

  Bell, Watermelon, Cherry, Single-Board A, Single-Board BD (Big Bonus (1), Big Bonus (2) or Big Bonus (3)) ), The number of judgment values of the big bonus (2) or the big bonus (3) is the same value in any of RT1, RT2 and RT3. The number of judgment values for A is 40020, and the number of judgment values for single roles B to D is 10332. Among the small roles, the winning combination is almost one of the single roles A and one of the single roles B to D. It has become.

  When one-piece combination A or one-piece combination B to D is won, regardless of the operation procedure of the stop buttons 12L, 12C, 12R, one-piece combination A, or one-piece combination B, one-piece combination C or one-piece combination Winning D, but the number of medals to be paid out is less than 3 bets set to play one game, so the payout rate in the gaming state of RT1, RT2, RT3 is less than 1, The number of medals held by the player will decrease (as will be explained below, the winning probability of replay is different for each of RT1, RT2 and RT3, but the number of medals will increase or decrease even if winning the replay Absent).

  When the bell is won, regardless of the operation procedure of the stop buttons 12L, 12C, 12R, the player will win the bell and the number of medals held by the player will increase. When the watermelon or cherry is won, the stop button 12L , 12C, 12R will be awarded to watermelon or cherry if the operating procedure is appropriate, the number of medals on hand will increase, but the winning probability of these combinations is very low, so 1 combination A, 1 It is not possible to cover the decrease in the number of medals due to winning of the winning combination B, single winning combination C or single winning combination D.

  Furthermore, the replay determination value numbers are 14792, 13299, and 8992 for RT1, RT2, and RT3, respectively. When winning the replay, regardless of the operating procedure of the stop buttons 12L, 12C, 12R, including the case where the big bonus (1), big bonus (2) or big bonus (3) win is carried over , Will win the replay. As in the case of replay, when winning a single combination A or single combination BD, including cases where the big bonus (1), big bonus (2) or big bonus (3) wins are carried over Regardless of the operation procedure of the stop buttons 12L, 12C, and 12R, one winning combination A, 1 winning combination B, 1 winning combination C, or 1 winning combination D will be won.

  In other words, excluding games that have been won by big bonus (1), big bonus (2), or big bonus (3), and considering only the games that have been won from the previous game, RT1, RT2, A chance to win the Big Bonus (1), Big Bonus (2), or Big Bonus (3) without winning any of the bells, one-piece combination A, one-piece combination B to D and replay in RT3 The probabilities of the occurrence of the game are 391 / 65536≈1 / 167.6, 1884 / 65536≈1 / 34.8, and 6191 / 65536≈1 / 10.6, respectively.

  Even if the stop button 12L, 12C, or 12R is operated in the operation procedure that can win the big bonus (1), the big bonus (2), or the big bonus (3), the watermelon or cherry may not be won. When the probability of occurrence of the game is reached, RT1 / RT2 / RT3 are 327 / 65536≈1 / 200.4, 1820 / 65536≈1 / 36.0, 6127 / 65536≈1 / 10.7, respectively.

  Here, as will be described later, the player is informed that the big bonus (3) is won, but the player is informed that the big bonus (1) or the big bonus (2) is won. Not notified. In other words, in the game that can win the big bonus (3), the stop buttons 12L, 12C, and 12R can be operated by an operation procedure corresponding to the game (provided that there is no operation error with respect to the target). The required number of games is only one game.

  On the other hand, in a game in which the big bonus (1) or (2) can be won, the operating procedure corresponding to the winning one of the big bonus (1) or the big bonus (2). Thus, the number of games required until the player can operate the stop buttons 12L, 12C, and 12R will be 1.5 on average (the big bonus (1) or (2) may be won). If you do n’t count the number of games that you ca n’t win between games).

  Therefore, if you do not consider winning in the game that was won by big bonus (1), big bonus (2) or big bonus (3) alone, the number of games required from winning of big bonus (3) to winning is: On average, RT1 has 167.6-200.4 games, RT2 has 34.8-36.0 games, and RT3 has 10.6-10.7 games. Considering the number of games required from the end of the big bonus game state to winning the big bonus (3), on average, it is 267.6-300.4 games for RT1, 134.8-136.0 games for RT2, RT3 means 110.6 to 110.7 games (however, if the set values are different, the number of these games will be different).

  In addition, the number of games required from winning the Big Bonus (1) or Big Bonus (2) to winning is, on average, 251.4-300.6 games for RT1, 52.2-54.0 games for RT2, In RT3, this is a 15.9 to 16.0 game. Considering the number of games required from the end of the Big Bonus gaming state to Big Bonus (1) or Big Bonus (2) winning, on average 351.4-400.6 games for RT1, 152.2- for RT2 154.0 games and RT3 are 115.9 to 116.0 games (however, if the set values are different, the number of these games will be different).

  Each of RT1, RT2, and RT3 reduces the number of medals held by the player, so it can be said that the gaming state is disadvantageous for the player. However, the big bonus (1), the big bonus (2), or the big bonus (3 ) Can be controlled to a big bonus that greatly increases the number of medals held by the player. If it is assumed that the game can be continued without winning the big bonus (1), big bonus (2) or big bonus (3), RT2 is higher than RT1 and RT3 is higher than RT2 by the higher replay winning probability. There will be less decrease in the number of medals.

  However, considering the increase in the number of medals in the big bonus controlled by winning the big bonus (1), big bonus (2) or big bonus (3), the big bonus (1), big bonus (2 ) Or Big Bonus (3), the number of games required to win is smaller (there is less reduction in the total number of medals), RT2 than RT1, RT3 than RT2 It can be said that the game state is advantageous for the player. Furthermore, a big bonus (2) with control to RT2 rather than a big bonus (1) with control to RT1 and a big bonus (2) with control to RT3 rather than a big bonus (2) with control to RT2 ( It can be said that 3) is a more advantageous role for the player.

  Note that in a game in which the big bonus (1), big bonus (2), or big bonus (3) is won alone, the player operates the stop button 12L, 12C, 12R according to an appropriate operation procedure according to what is won. Of course, it is possible to win a big bonus (1), a big bonus (2) or a big bonus (3) if possible. Big Bonus (1), Big Bonus (2) or Big Bonus (3) alone won in that there can be a Big Bonus (1), Big Bonus (2) or Big Bonus (3) in the winning game Can be said to be more advantageous for the player than the simultaneous winning of the single-player roles B to D.

  In the slot machine 1, a game is progressed by repeating the game. Each game is started by the player operating the start lever 11 to rotate the reels 3L, 3C, 3R. Before starting each game, the player can insert a medal from the medal slot 13. By inserting or operating one BET button 14 or MAXBET button 15, three medals are inserted and the number of bets is set. However, if the result of the previous game was a replay win, the bet number is automatically set, and the player does not need to perform an operation for setting the bet number.

  After the reels 3L, 3C, and 3R are rotated, the player sequentially operates the stop buttons 12L, 12C, and 12R (however, in any order), and rotates the reels 3L, 3C, and 3R. Are stopped sequentially. The reels 3L, 3C, and 3R are rotated when there is a reel that has already been stopped according to the winning flag set in the RAM 112 according to the result of the internal lottery and the operation timing of each of the stop buttons 12L, 12C, and 12R. According to the symbol displayed on the stopped reel, the reel is stopped.

  When all the rotations of the reels 3L, 3C, and 3R are stopped and the display result is derived to the variable display device 2, one game is finished. When a combination of symbols (bell, watermelon, cherry, single-piece roles A to D) is derived on any winning line of the variable display device 2, the winning combination is determined according to the type of the winning combination. Number of medals are paid out (however, until the number of credits reaches 50, medals are paid out by adding credits). When a replay symbol combination is derived on any winning line of the variable display device 2, a replay winning is made, and the bet number for executing the next game is automatically set.

  When a symbol combination of big bonus (1), big bonus (2), or big bonus (3) has been derived on any winning line of the variable display device 2, a big bonus medium flag is set in the RAM 112, and the next The gaming state applied from the game is controlled to a big bonus. At this time, the RT1 in-progress flag, the RT2 in-progress flag, and the RT3 in-progress flag corresponding to the gaming state (RT1, RT2 or RT3) controlled until then are deleted.

  When the symbol combination of big bonus (1), big bonus (2) or big bonus (3) has been derived, the RT1 medium flag, RT2 medium flag or RT3 medium flag is also newly set in the RAM 112 in accordance with the type. However, RT1, RT2, and RT3 do not occur until the big bonus ends when the number of payout medals in the big bonus exceeds 390 (the big bonus medium flag is deleted). When the big bonus ends, the gaming state is controlled to RT1, RT2 or RT3 based on the RT1 flag, RT2 flag, and RT3 flag set in the RAM 112.

  In order to produce an effect in accordance with the progress of such a game, commands are transmitted from the game control board 101 to the effect control board 102 as needed according to the progress of the game. The commands transmitted from the game control board 101 to the effect control board 102 include at least a winning status notification command, a winning information command, and a gaming 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 winning status notification command indicates the setting status of the winning flag in the RAM 112, and is transmitted when the start lever 11 is operated and an internal lottery is performed. The winning information command indicates a type of a winning generated according to the display result of the variable display device 2, and is transmitted when the display result is derived to the variable display device 2 and a winning determination is made. The gaming state command indicates a gaming state applied in the next game, and is transmitted at the end of one game.

  Next, an effect process executed by the CPU 121 of the effect control board 102 in the slot machine 1 according to this embodiment will be described. The effects executed by the CPU 121 of the effect control board 102 include effects by displaying images on the liquid crystal display 4, effects by sound output from the speakers 7L, 7R and 7U, reel lamps 3LP and game effect lamps 75A to 75M. There is an effect by lighting control of lamps.

  An effect unique to the slot machine 1 according to this embodiment is that a winning status notification command indicating a setting status of a winning flag based on the result of an internal lottery performed when the start lever 11 is operated by a player is transmitted. As such special effects, there are special effects, turn effects, and notice effects. These special effects are not executed while the gaming state is controlled by the big bonus, and are transmitted at the end of the previous game to determine whether the gaming state is controlled by the big bonus. The gaming state indicated by the played gaming state command is stored in the RAM 122.

  First, the special effect will be described. The special effect is when the big bonus (3) accompanied by the transition to RT3 that is most advantageous to the player can be won relatively easily, that is, the big bonus (3) winning flag is set and other small bonuses are set. This is an effect that is executed when a winning combination or replay winning flag is not set. In addition to the big bonus (3) winning flag, even when the watermelon or cherry winning flag is set, it is impossible to win the big bonus (3) depending on the operation procedure of the stop buttons 12L, 12C, 12R. However, since the winning of watermelon or cherry is given priority, it is very difficult to win the big bonus (3), so the special performance is not executed.

  Note that the special effect is set until the Big Bonus (3) winning flag is set, and if no other small role or replay winning flag is set, the Big Bonus (3) is won (when the special effect is executed). However, since the player may not accidentally win the big bonus (3) by operating the stop buttons 12L, 12C, and 12R), the game is executed any number of times.

  Next, the talk effect will be described. The roll effect is an effect that is executed when the winning flag of big bonus (1), big bonus (2) or big bonus (3) and / or the winning flag of one-piece combination BD is set. is there. A general player operates the stop buttons 12L, 12C, and 12R from the left to the right in one game in a situation where there is no special situation. In this way, the left stop button 12L is operated first. When this occurs, the left reel 3L stops first while the middle and right reels 3C, 3R are still rotating.

  The left stop button 12L is operated first when the big bonus (1), big bonus (2) or big bonus (3) winning flag and / or the winning flag of one-piece combination BD are set. Then, any one of “red 7,” “blue 7,” and “white 7” is always displayed on the left reel 3L. “Red 7”, “Blue 7” or “White 7” is displayed on the left reel 3L, and when the middle and right reels 3C and 3R are still rotating, the big bonus (1) and the big bonus Since the player can expect the winning of (2) or the big bonus (3), the roaring effect is executed to effectively increase the player's expectation. Note that when the special effect has already been executed (including the execution in the game), the roaring effect is not executed.

  Next, the notice effect will be described. The notice effect is an effect for notifying the possibility of winning the big bonus (1), big bonus (2), or big bonus (3), and the types of the notice effects are A, B, C, and D. There are four types. The notice effect is not executed at all when the special effect is already executed (including execution in the game), but may not be executed even if the special effect is not executed. The notice effect is executed according to the determination in each game, but this determination is performed regardless of the execution of the turn effect.

  FIG. 7 is a diagram showing a table for determining the type of notice effect to be executed in each game. The probabilities of determining A, B, C, D, and None as the types of notice effects are 5% and 10% respectively when the big bonus (1), big bonus (2), and big bonus (3) are won. %, 10%, 5%, 70%, 5%, 6%, 3%, 1 when the big bonus (1), big bonus (2) and big bonus (3) are not won %, 85%. The player predicts to some extent whether or not the big bonus (1), the big bonus (2), or the big bonus (3) is won depending on whether or not the notice effect is executed or the type of the notice effect executed. It is possible.

  Hereinafter, processing performed by the CPU 121 of the effect control board 102 in order to perform the effects as described above will be described. Here, only the processes necessary for the execution of the above-described special effect, turn effect, and notice effect will be described. FIG. 8 is a flowchart 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 S101). When any command is received from the game control board 101, it is determined what kind of the received command is (step S102).

  If the type of the received command is a winning status notification command transmitted according to the result of the internal lottery performed when the start lever 11 is operated, the gaming state command received at the end of the previous game will be shown as will be described later. It is determined whether or not the gaming state (that is, the gaming state applied in the current game) indicates a big bonus (step S103). If it shows that it is a big bonus, it will return to the process of step S101 as it is.

  If it is not indicated that it is a big bonus, since the gaming state applied in this game is one of RT1, RT2 and RT3, the received winning status notification command is set with the big bonus (3) winning flag. Then, it is determined whether or not another winning combination or replay winning flag is not set (step S104). If the big bonus (3) winning flag is set and indicates that no other small role or replay winning flag is set, a special effect is executed (step S105), and an effected flag is set in the RAM 122. (Step S106). Then, the process returns to step S101.

  It indicates that the big bonus (3) winning flag is not set, or even if it indicates that the big bonus (3) winning flag is set, the winning flag for other small role or replay is set If so, it is determined whether or not the effected flag is set in the RAM 122 (step S107). If the effected flag is set, the process returns to step S101 as it is without executing the turning effect or the notice effect.

  If the effected flag is not set, the received winning status notification command is a winning flag of big bonus (1), big bonus (2) or big bonus (3) and / or winning of one-piece roles B to D It is determined whether or not the flag is set (step S108). If it is shown that none of the big bonus (1), big bonus (2) and big bonus (3) winning flags, and the winning combination of the single winning combination BD are set, the process of step S110 is performed. move on.

  If the winning flag of big bonus (1), big bonus (2) or big bonus (3) and / or the winning flag of one-piece combination B to D is set, the roaring effect is executed. (Step S109), the process proceeds to step S110. In step S110, the type of the notice effect is determined with reference to the table shown in FIG. 7 according to whether the big bonus (1), big bonus (2) or big bonus (3) is won, and A, B , C, or D is determined, the determined type of notice effect is executed. When it is determined that there is no notice effect, the notice effect is not executed. Then, the process returns to step S101.

  If the received command type is a gaming status command transmitted at the end of one game, the gaming status indicated by the received gaming status command is stored in a predetermined area of the RAM 122 (step S111). Next, it is determined whether or not the gaming state indicated by the received gaming state command (that is, the gaming state applied in the next game) indicates a big bonus (step S112). If it indicates that it is a big bonus, if the effected flag is set in the RAM 122, it is deleted (step S113), and the process returns to step S101. If it indicates that it is not a big bonus, the process directly returns to step S101.

  Hereinafter, the progress of the game in the slot machine 1 according to this embodiment will be described based on a specific example. FIG. 9 is a view for explaining an example of the progress of the game in the slot machine 1 according to this embodiment. In FIG. 9A, the game is progressed by winning and winning the big bonus (1), and in FIG. 9B and FIG. 9C, the game is progressing by winning and winning the big bonus (3). Show. In this example, it is assumed that the game is progressed with an average number of games calculated based on the winning probabilities of the respective combinations.

  In the example shown in FIG. 9A, first, it is assumed that the big bonus (1) is won. When the big bonus (1) is won, the gaming state is controlled to the big bonus. When the total number of payout medals in the big bonus exceeds 390, the gaming state is controlled by RT1. Then, when approximately 100 games are consumed in RT1, it is assumed that the big bonus (1) +1 winning combination B to D is won (the single bonus combination B to D is more than the single winning of the big bonus (1)). If you win simultaneously, the probability is significantly higher).

  In a game that is won for Big Bonus (1) + 1 Bonus B to D, either 1 Bonus B, 1 Duo C or 1 Duo D will be won, so winning the Big Bonus (1) impossible. After that, the game is lost, and it takes 168 to 200 games on average before the stop buttons 12L, 12C, and 12R can be operated by the operation procedure corresponding to the big bonus (1) (lost game). It is assumed that whether the stop buttons 12L, 12C, and 12R are operated in accordance with the operation procedure corresponding to the big bonus (1) or the big bonus (2) is equivalent).

  During the 268-300 games from the end of the Big Bonus game state to RT1 control until the second Big Bonus (1) is won, nearly 80% of the games are played as 1 A Winning a winning combination B, 1 winning combination C or 1 winning combination D decreases by 2 medals, most of the remaining winning replay does not increase medals, and a big bonus (1) + 1 winning combination B In the game up to winning D, the result of losing in the internal lottery is also losing, so the number of medals increased by the big bonus controlled based on the first big bonus (1) winning is more than the player's The number of medals on hand will decrease.

  In the example shown in FIG. 9B, first, it is assumed that the big bonus (3) is won. When the big bonus (3) is won, the gaming state is controlled to be a big bonus. When the total number of payout medals in the big bonus exceeds 390, the gaming state is controlled by RT3. Then, when approximately 100 games are consumed in RT3, it is assumed that the big bonus (3) is won (the one that wins the big bonus (3) alone is the simultaneous winning with the single roles B to D) Is much higher in terms of probability).

  In a game where only the big bonus (3) is won, the big bonus (3) winning flag is set and the winning flags of other roles are not set, so that special effects are executed. ing. The player sees the special effect and operates the stop buttons 12L, 12C, 12R according to the operation procedure corresponding to the big bonus (3), and can immediately win the big bonus (3).

  In other words, the number of games from the end of the big bonus game state to winning the second big bonus (3) is 100 games until winning the big bonus (3). The gaming state of the new big bonus can be controlled with a reduced number smaller than the number of medals increased with the big bonus controlled based on the winning of (3), and the number of medals held by the player can be increased. it can.

  In the example shown in FIG. 9C, it is assumed that the big bonus (3) is won first. When the total number of payout medals in the big bonus exceeds 390, the gaming state is controlled by RT3. Then, when about 100 games are consumed in RT3, it is assumed that the big bonus (3) +1 winning combination B to D has been won (although the big bonus (3) and the single winning combination B to D are simultaneously won in the first place) Probability is not very high).

  In a game won for Big Bonus (3) + 1 Bonus B to D, either 1 Bonus B, 1 Duo C or 1 Duo D must be won, so winning the Big Bonus (3) impossible. However, the result of the internal lottery is lost in about 11 games from there. In the game where the result of the internal lottery is lost, the big bonus (3) winning flag is set and the winning flags of other roles are not set. It has become. The player can win the big bonus (3) by watching this special effect and operating the stop buttons 12L, 12C, 12R according to the operation procedure corresponding to the big bonus (3).

  That is, the number of games from the end of the big bonus game state to winning the second big bonus (3) is greater than the 100 games until winning the big bonus (3), but the number of games increasing. The total number of games is about 11 and about 111 games. Even if a decrease in the number of medals in the 11 games increased, a new big bonus gaming state with a reduced number smaller than the number of medals increased with the big bonus controlled based on the first big bonus (3) winning. The number of medals held by the player can be increased.

  As described above, in the slot machine 1 according to the present embodiment, the special bonus such as the big bonus (1), the big bonus (2), or the big bonus (3) is used as the lottery target in the RT1, RT2, and RT3. , Replay replay game, bell, watermelon, cherry, 1-sheet role A, 1-sheet role B, 1-sheet role C or 1-sheet role D. In order to win each of these winning combinations, it is necessary to win the internal lottery and set the winning flag, but depending on the operating procedure of the stop buttons 12L, 12C, 12R, the winning combination may not be possible. Among them, the winning flags of the special bonus, such as the big bonus (1), the big bonus (2), or the big bonus (3), are carried over after the next game until actually winning.

  Therefore, for example, in a game in which the winning flag of big bonus (1), big bonus (2) or big bonus (3) is carried over, the big bonus (1) can be obtained by winning a replay or small role in the internal lottery. In some cases, the winning flag of big bonus (2) or big bonus (3) is set, and the winning flag of any replay or small role is also set. Big Bonus (1), Big Bonus (2), Big Bonus (3) and Big Bonus (1), Big Bonus (2) or Big Bonus (3) The flag is set, and the winning flags of the single winning combinations B to D, which are small combinations, are set.

  Here, a winning flag for big bonus (1), big bonus (2) or big bonus (3) is set, and a winning flag for bell, one-piece combination A, one-piece combination B to D or replay is also set. Sometimes, the player wins the winning combination of the bell, the single winning combination A, the single winning combination B to D, or the replay regardless of the operating procedure of the stop buttons 12L, 12C, 12R. The big bonus (1), the big bonus (2) or the big bonus (3) will not be won.

  When the winning flag of big bonus (1), big bonus (2) or big bonus (3) is set, and no winning flag of bell, one-piece combination A, one-piece combination B to D and replay is set In addition, it is possible to win the big bonus (1), the big bonus (2) or the big bonus (3) according to the operating procedure of the stop buttons 12L, 12C, 12R. When the winning flag of big bonus (1), big bonus (2) or big bonus (3) is set and the winning flag of watermelon or cherry is set, big bonus (1), big bonus (2) or big Although it is not completely impossible to win the bonus (3), it is very difficult to operate the stop buttons 12L, 12C, and 12R in the operation procedure for winning.

  In this way, when controlled by RT1, RT2 or RT3, when winning a small role or replay, it is possible to win the big bonus (1), big bonus (2) or big bonus (3). Even if it is not possible (or very difficult), it will be used for a small role or replay that has been elected so as not to win the big bonus (1), big bonus (2) or big bonus (3). You won't be able to win a prize. As a result, it is possible to prevent the player from being dissatisfied because the winning combination cannot be won in any of the winning combinations in RT1, RT2 or RT3.

  By the way, after winning the big bonus (1), the big bonus (2) or the big bonus (3) and the big bonus controlled based on the winning is finished, Depending on the type, it is controlled to RT1, RT2 or RT3. The main small combination that is won with a high probability in RT1, RT2, and RT3 is the single combination A or the single combination B to D. The number of medals to be paid out to a player by winning a single combination A, single combination B, single combination C or single combination D is one, and is used to set the number of bets for playing one game. Less than 3 medals required. Thereby, the payout rate of medals in RT1, RT2, and RT3 is less than 1, and when the game state is controlled, the number of medals held by the player is also decreased. Therefore, when controlled by RT1, RT2 or RT3, it is advantageous for the player to win the big bonus (1), big bonus (2) or big bonus (3) as soon as possible.

  Here, RT1 has a relatively high probability of winning a replay, and the probability of being lost in any of the bell, single-player combination A, single-player combinations B to D, and replay (and also lost in watermelon or cherry). Is low. RT2 has a lower replay win probability than RT1, and the probability that it will be lost in any of the bell, single piece A, single pieces BD and replay (and also lost in watermelon or cherry) is: It is higher than RT1. RT3 has a lower replay win probability than RT2, and the probability of being lost in any of the bell, single piece A, single pieces BD and replay (and also lost in watermelon or cherry) is , Even higher than RT2.

  In other words, even if the big bonus controlled by winning the big bonus (1), big bonus (2) or big bonus (3) is the same, it is controlled after the end of the big bonus based on the winning of the big bonus (2). RT2 has a smaller number of games than RT1, which is controlled after the end of the big bonus based on the big bonus (1), and a new big bonus (1), big bonus (2) or big bonus (3) It will be possible to win a prize. Furthermore, the RT3 controlled after the end of the big bonus based on the big bonus (3) winning has a smaller number of games than the RT2 controlled after the end of the big bonus based on the big bonus (2) winning. It is possible to win a big bonus (1), a big bonus (2) or a big bonus (3).

  As a result, even if the gaming state of the big bonus controlled by winning is the same, the player is given the choice of winning the big bonus (1), big bonus (2), or big bonus (3). Can interest you. Whether the big bonus (1), big bonus (2), or big bonus (3) is won depends on whether the big bonus (1) or big bonus (2) is reached after the gaming state of the big bonus ends. Or, since it affects the number of games until winning the big bonus (3), the player's interest is also extended over a long period of time, and the big bonus (1), big bonus (2) or big bonus ( 3) It is possible to increase the player's interest in which of the winning prizes.

  In RT1, RT2 or RT3, the big bonus (1), the big bonus (2) or the big bonus (3) may be simultaneously won together with the single winning combination B to D. There is a case where any combination including B to D is won simultaneously without winning simultaneously. In a game in which the big bonus (1), big bonus (2), or big bonus (3) is elected alone, depending on which of the big bonus (1), big bonus (2), or big bonus (3) is won If the player operates the stop buttons 12L, 12C, and 12R according to the operation procedure, it is possible to immediately win the big bonus (1), big bonus (2), or big bonus (3) in the game.

  In this way, in RT1, RT2 or RT3, there is a game in which the big bonus (1), big bonus (2) or big bonus (3) is won independently without winning simultaneously with other roles. Judging from the effects such as the big bonus (1), big bonus (2) and big bonus (3), even if it is considered that it has not been won by the previous game, 1) The player can be expected to win the big bonus (2) or the big bonus (3), and the fun of the game can be improved.

  Here, when winning the big bonus (1), the big bonus (2) or the big bonus (3), the probability that the single bonus combination B to D is not won at the same time without winning simultaneously is the big bonus (2). Is higher than the big bonus (1), and the big bonus (3) is higher than the big bonus (2). In particular, in the case of big bonus (3), the probability of winning alone is overwhelmingly higher than the simultaneous winning of single-player roles B to D, and it is often possible to win in the winning game. Big Bonus (3) while the number of digested games after the game state is relatively small (compared to winning the Big Bonus (1) and Big Bonus (2) in the same RT) Can be awarded.

  When the game state is controlled to the big bonus by winning the big bonus (3), the game is controlled to RT3 after the end of the big bonus, so here the big bonus ends as compared to the case where it is controlled by RT1 or RT2. Therefore, within the relatively small number of digested games, a new big bonus (1), big bonus (2), or big bonus (3) can be won, and the gaming state of the big bonus can be controlled. By this chain, if the big bonus (3) is won, the game state can be repeatedly controlled in the big bonus in a short period of time, increasing the player's expectation and improving the interest of the game Can be made.

  Moreover, in a game in which the big bonus (3) winning flag is set and the winning flags of other roles are not set, that is, if the operating procedure of the stop buttons 12L, 12C, 12R is appropriate, the big bonus (3) is won. In the game that can be played, special effects are executed. That is, when the special effect is executed, the player knows that the stop button 12L, 12C, 12R should be operated according to the operation procedure corresponding to the big bonus (3). The big bonus (3) can be surely won in the executed game.

  Thus, when the big bonus (3) is won, the RT (RT1, RT2 or RT3) is terminated with a smaller number of games than when the big bonus (1) or the big bonus (2) is won, and a new big bonus is obtained. The gaming state can be controlled. Moreover, since the big bonus (3) has a high probability of winning alone, the expected number of games from winning the big bonus (3) to winning is the winning from the winning of the big bonus (1) or big bonus (2). Compared to the expected value of the number of games up to, it will be very small. As a result, among the big bonus (1), the big bonus (2) and the big bonus (3), the player's profit when winning the big bonus (3) can be further increased. Interest can be improved.

  The big bonus (1) is overwhelmingly more likely to be won simultaneously with a single role B to D than to win alone, but the transition to RT2, which is disadvantageous than RT3 but advantageous over RT1 In the big bonus (2) accompanied by, the probability of winning alone and the probability of winning at the time for one-piece roles B to D are the same. Therefore, even in the case of the big bonus (2), compared to the big bonus (1), after the gaming state of the previous big bonus is finished, the game is won with a smaller number of games and controlled to a new big bonus gaming state. Even after the end of the new big bonus, the game state of the new big bonus can be controlled with a small number of games. By this chain, when the big bonus (2) is won, the game state can be repeatedly controlled by the big bonus in a shorter period of time compared to the case where the big bonus (1) is won. The expectation of the game can be raised and the interest of the game can be improved.

  By the way, in RT1, RT2 or RT3, in a game in which one player A, one player B to D, replay, or bell is elected, no matter how big the player operates the stop buttons 12L, 12C, 12R. No bonus (1), big bonus (2) or big bonus (3) will be won. However, even if it is a game that has not been won by RT1, RT2 or RT3 for single-player A, single-player BD, replay, or bell, big bonus (1), big bonus ( If 2) or Big Bonus (3) is not won, the Big Bonus (1), Big Bonus (2) or Big Bonus (3) will not be won in the first place.

  In the slot machine 1 according to this embodiment, when the special effect is not yet executed in RT1, RT2 or RT3, whether or not the big bonus (1), the big bonus (2) or the big bonus (3) is won. The type of the notice effect (including none) is determined at different probabilities depending on the type of the notice effect, and the determined type of notice effect is executed. Accordingly, even if the big bonus (1), the big bonus (2), or the big bonus (3) cannot be won, the big bonus (1 ), The player can be expected to win the big bonus (2) or the big bonus (3), and the interest of the game can be improved.

  Furthermore, the symbol combinations of big bonus (1), big bonus (2) and big bonus (3) are “red 7-red 7-red 7”, “blue 7-blue 7-blue 7”, “white”. "7-White 7-White 7", but each symbol combination of 1-sheet combination B, 1-sheet combination C, and 1-sheet combination D, which are simultaneously selected with these, is "Red 7-Bell-Bell" "Blue 7-bell-bell" and "White 7-bell-bell".

  Big Bonus (1), Big Bonus, regardless of whether Big Bonus (1), Big Bonus (2) or Big Bonus (3) is also won You will never win (2) or Big Bonus (3). However, many players operate the left stop button 12L first when there is no special circumstances in proceeding with the game in the slot machine 1, and thus the left reel 3L is the first. Will be stopped.

  When one of the winning combinations B to D is won, when the first left stop button 12L is operated, “red 7”, “blue 7” or “white 7” is stopped and displayed on the left reel 3L. The situation where the right reels 3C and 3R are still rotating will occur. Judging from this situation alone, there is a possibility of winning the big bonus (1), big bonus (2), or big bonus (3). Thus, even when the player first operates the left stop button 12L and the left reel 3L stops, the player can play the big bonus (1), big bonus (2), or big bonus ( It is still possible to expect a prize for 3), and the fun of the game can be further improved.

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

  In the above embodiment, in a game that has not yet won the big bonus (1), big bonus (2), or big bonus (3) in RT1, RT2, RT3, the big bonus (1), big bonus (2) And Big Bonus (3), both when winning alone and when winning simultaneously with single-player roles B to D. The ratio of either single winning or simultaneous winning is the Big Bonus (1), Big bonus (2) and big bonus (3) were different. That is, the big bonus (3) to be transferred to RT3 (the most advantageous for the player among RT1 to RT3) after the big bonus game state is finished has a high percentage of single winning, and the game state of the big bonus is The big bonus (1) to be transferred to RT1 (the most unfavorable for the player among RT1 to RT3) after the completion has a low percentage of single winning.

  On the other hand, Big Bonus (3) which is transferred to RT3 (the most advantageous for the player among RT1 to RT3) after the Big Bonus gaming state is finished has a low ratio of single winning, The big bonus (1) to be transferred to RT1 (the one that is most disadvantageous for the player among RT1 to RT3) after the gaming state is ended may have a high single winning percentage.

  For example, as shown in the winning combination table by gaming state in FIG. 10, the big bonuses in the games that have not yet won the big bonus (1), big bonus (2), or big bonus (3) in RT1, RT2, RT3. The number of determination values for big bonus (1) to be controlled by RT1 after the gaming state is over is as large as 200 for the single winning combination (the number of determination values for the simultaneous winning combination of 1 player combination B to D is as small as 18). ) The big bonus (3) to be controlled by the RT3 after the big bonus game state is finished has a small number of determination values for the single winning 18 and the number of determination values for the simultaneous winning of the single winning combination B to D is 200. May be large).

  In this case, when setting the probability of single winning of big bonus (1), big bonus (2) or big bonus (3) and the probability of simultaneous winning of each of these and one piece combination BD The special effect may not be executed even in a game in which the winning flag of the big bonus (3) is set and the winning combination of other small role or replay is not set. Alternatively, when the winning flag for other small role or replay is not set, not only when the winning flag for big bonus (3) is set, but also the winning flag for big bonus (1) or big bonus (2) Even when is set, a special effect may be executed. However, only when the big bonus (3) winning flag is set and the winning combination flag for any other small role or replay is not set, it is not excluded that the special effect is executed.

  In this way, by setting the probability of winning the big bonus (1), the big bonus (2) or the big bonus (3) alone and the probability of simultaneously winning these combinations and the single combination BD, As the number of digest games after the end of the big bonus game state increases, it can be expected that the winner will be the big bonus (3) with the transition to RT3, which is advantageous to the player. become. As a result, even if the number of digest games increases without winning the Big Bonus (1), Big Bonus (2), or Big Bonus (3) after the Big Bonus game state ends, The interest of the game can be improved without discouraging the player.

  In the above embodiment, if the big bonus (3) winning flag is set when the special effect has not yet been executed at RT1, RT2 or RT3, any other small role or replay winning is set. Only when the flag is not set, the special effect is executed. However, even if a winning flag for a role other than the big bonus (3) winning flag is also set, if the role is watermelon or cherry, it is impossible to win the big bonus (3). (However, the operation of the stop buttons 12L, 12C, and 12R is more difficult than when no winning flag other than the big bonus (3) winning flag is set).

  Therefore, when the winning flag set together with the big bonus (3) winning flag is a watermelon or cherry winning flag, a special effect is executed in the same manner as when no winning flag of any combination is set. It may be a thing. When the winning flag of watermelon or cherry is set together with the big bonus (3) winning flag, the special effect executed when any winning flag of the role other than the winning flag of the big bonus (3) is not set It is good also as a thing with a different aspect from the special production performed.

  In the above embodiment, when the special effect is not yet executed at RT1, RT2 or RT3, the winning flag of big bonus (1), big bonus (2) or big bonus (3) and / or one sheet In a game in which the winning flags of the roles B to D are set, the roaring effect is always executed. However, even in a game in which the winning flag for the big bonus (1), the big bonus (2) or the big bonus (3) and / or the winning flag for the one-player role B to D is set, the roaring effect may not be executed. There may be.

  Here, a game in which a winning flag of Big Bonus (1), Big Bonus (2) or Big Bonus (3) is set (including a case where a winning flag of 1 double combination B to D is set) In this case, it is possible to increase the execution probability of the roaring effect as compared to a game in which only the winning combinations B to D are set. As a result, when the roaring effect is executed, the player's expectation for winning the big bonus (1), the big bonus (2), or the big bonus (3) can be further enhanced. Interest can be improved.

  In the above embodiment, when the special effect is not yet executed at RT1, RT2 or RT3, the winning flag of big bonus (1), big bonus (2) or big bonus (3) and / or one sheet In the game in which the winning flags of the roles B to D are set, the turning effect is executed, but the execution timing of the turning effect is the timing at which the winning status notification command is transmitted to the effect control board 102, that is, the player It was the timing when one game was started by operating the start lever 11.

  On the other hand, the execution timing of the roaring effect in the game in which the winning flag of the big bonus (1), the big bonus (2) or the big bonus (3) and / or the winning flag of the single role BD is set. Is the timing at which the first stop button (the one operated first among the stop buttons 12L, 12C, 12R) is operated, or the first reel (the first among the reels 3L, 3C, 3R). It may be the timing at which (the one to be) is stopped. Only when the left stop button 12L serves as the first stop button or when the left reel 3L serves as the first reel, it is possible to execute the turn effect.

  As described above, the red reel 3L is turned to “red 7” by executing the turning effect in accordance with the timing when “red 7”, “blue 7”, or “white 7” is stopped and displayed on the left reel 3L. , “Blue 7” or “White 7” is stopped and displayed (this is part of the symbol combination of Big Bonus (1), Big Bonus (2) or Big Bonus (3)) In conjunction with the state), the player's expectation for winning the big bonus (1), big bonus (2) or big bonus (3) can be increased more effectively, and the game is more interesting. Can be improved.

  In the above embodiment, when the special effect is not yet executed at RT1, RT2 or RT3, depending on whether or not the big bonus (1), big bonus (2) or big bonus (3) is won. The notice effect was supposed to be executed. In each game at such time, the types of notice effects are A, B, C, and B with different probabilities depending on whether the big bonus (1), big bonus (2) or big bonus (3) is won. D or none is determined, and the determined type of notice effect is executed (when no answer is determined, no type of notice effect is executed).

  However, the method of changing the execution state of the notice effect depending on whether the big bonus (1), the big bonus (2), or the big bonus (3) is won is not limited to this. For example, the probability of selecting no notice effect is the same regardless of whether the big bonus (1), big bonus (2), or big bonus (3) is won. When it is to be executed, the selection probability of the type of notice effect may differ depending on whether the big bonus (1), the big bonus (2) or the big bonus (3) is won.

  For example, a 70% chance of not producing a notice effect regardless of whether the big bonus (1), big bonus (2) or big bonus (3) is won, but the types of notice effects are A, B, The probabilities of determining C and D are 5%, 10%, 10% and 5%, respectively, when the big bonus (1), big bonus (2) or big bonus (3) is won. (1) When neither the big bonus (2) nor the big bonus (3) is won, it may be 10%, 12%, 6%, and 2%, respectively.

  Alternatively, different types of notice effects may be executed depending on whether the big bonus (1), the big bonus (2), or the big bonus (3) is won. A, B, C, and D can be selected as the types of notice effects, whether or not the big bonus (1), big bonus (2), or big bonus (3) is won. The notice effect type E may be selected at a predetermined rate only when the big bonus (1), the big bonus (2), or the big bonus (3) is won.

  In the above embodiment, the big bonus (3) winning flag is set when the special effect is not yet executed in RT1, RT2 or RT3, and any other small role or replay winning flag is set. The CPU 121 of the effect control board 102 determines that there is no winning situation notification command, and the special effect is executed under the control of the CPU 121 of the effect control board 102.

  However, when the special effect is not yet executed at RT1, RT2 or RT3, the big bonus (3) winning flag is set, and any other small role or replay winning flag is not set. A freeze effect that makes the progress of the game impossible for a certain period of time as judged by the CPU 111 of the board 101 (for example, even if the start lever 11 is operated and a predetermined minimum time has elapsed for one game, the reels 3L, 3C still It is also possible to execute an effect that does not start the rotation of 3R. While the freeze effect is being executed under the control of the CPU 111 of the game control board 101, it is determined that the big bonus (3) winning flag is set and that no other small role or replay winning flag is set. The CPU 121 of the effect control board 102 may determine based on the situation notification command and execute an effect linked with the freeze effect.

  In the above embodiment, the main small combination in RT1, RT2 and RT3 is a single combination A in which only one medal is paid out by winning, or a single combination B, a single combination C or a single combination D, By using these as the main small roles, the number of medals held by the player in the gaming state of RT1, RT2, RT3 is supposed to decrease. However, if the number of medals held by the player can be reduced as a whole of the gaming state of RT1, RT2, RT3, only two medals less than three bets set for one game are paid out. A two-piece role may be used as the main small role. The one-piece combination A is applied as it is, but instead of the one-piece combination B, the one-piece combination C or the one-piece combination D, the two-piece combination B, the two-piece combination C or the two-piece combination D ( Conditions other than the number of medals to be paid out may be the same as the single combination B, the single combination C, and the single combination D).

  In the above embodiment, the big bonus that ends when the total number of medals paid out exceeds 390 regardless of whether the big bonus (1), the big bonus (2), or the big bonus (3) is won. Depending on whether the Big Bonus (1), Big Bonus (2) or Big Bonus (3) was won, it was paid out. The upper limit of the number of medals may be controlled by a big bonus.

  For example, when winning the big bonus (3), the bonus is controlled on the condition that the total number of medals paid out exceeds 390, and is controlled to RT3 after the end of the big bonus. When winning the big bonus (1), the bonus may be controlled to be terminated on condition that the total number of paid-out medals exceeds 405, and then controlled to RT1 after the big bonus is terminated. In this case, comparing the case of winning the big bonus (1) with the case of winning the big bonus (3), the number of medals that the player can acquire with the first controlled big bonus is the big bonus (1). There are more people who won the prize.

  However, in RT1, which is controlled after the big bonus game state is ended based on the big bonus (1) winning, until the next big bonus (1), big bonus (2) or big bonus (3) is won. The expected value of the decreased number of medals is still larger than the expected value of the increased number of medals with the previously controlled big bonus. On the other hand, in RT3 controlled after the big bonus game state is ended based on the big bonus (3) winning, the medal until winning the big bonus (1), big bonus (2) or big bonus (3) The expected value of the decreased number of medals becomes smaller than the expected value of the increased number of medals with the big bonus controlled before that. Therefore, it can be said that the big bonus (3) is more advantageous for the player than the big bonus (1).

  As described above, the advantage for each player of the big bonus (1), the big bonus (2), and the big bonus (3) is that the medal increases in the gaming state of the big bonus that is controlled first after winning the prize. Judgment can be made based on the sum of the expected value of the number of sheets and the expected value of the decreased number of medals in the RT after the gaming state of the big bonus has ended.

  In the above embodiment, the big bonus (1) is set to RT1 after the end of the big bonus controlled by the big bonus (1) and the RT2 is set to the big bonus (2) after the end of the big bonus controlled by the big bonus (2). After the end of the big bonus controlled by the winning of 3), each is controlled to RT3. When the set value is changed when the power of the slot machine 1 is turned on, the state before the change of the set value may be maintained, or one of RT1, RT2 and RT3 is determined in advance. It is good also as what controls. If the data in the RAM 112 is initialized when the power of the slot machine 1 is turned on (the setting value may or may not be changed), one of RT1, RT2 or RT3 is determined in advance. Can be controlled.

  In the above embodiment, the bonus game state controlled by winning the special role includes a big bonus controlled by winning the big bonus (1), big bonus (2), or big bonus (3). In addition to or in addition to these, a regular bonus is provided as a special role, and the bonus is controlled to the regular bonus gaming state (the gaming state in which the regular bonus in the above big bonus is provided for one set). It is possible to provide a challenge bonus as a special role and control the game state of the challenge bonus by winning the prize.

  When the gaming state is the challenge bonus, the maximum stop delay time for the right reel 3R is shortened from the normal 190 milliseconds to 75 milliseconds, and only one frame can be drawn, but depending on the result of the internal lottery It is possible to win prizes such as bells and cherries (that is, the winning flags of these prizes are set regardless of the internal lottery). That is, regardless of the result of the internal lottery, a small role can be won according to the operation procedure of the stop buttons 12L, 12C, 12R. The gaming state of the challenge bonus can be ended when, for example, the number of medals paid out to the player exceeds 259.

  In the above embodiment, both the RAM 112 of the game control board 101 and the RAM 122 of the effect control board 102 are backed up by the battery, and the stored data is stored even when the power of the slot machine 1 is turned off. It was to be retained. However, only the RAM 112 of the game control board 101 needs to be backed up by the battery, and the RAM 122 of the effect control board 102 does not back up the battery and stores the data stored when the power of the slot machine 1 is turned off. May disappear.

  In the above embodiment, the RAM 112 of the game control board 101 is initialized by changing the set value. However, the counter for counting the number of steps of the stepping motors constituting the reel motors 3ML, 3MC, and 3MR, respectively. Only the value was not initialized. This prevents the player from perceiving that the setting values are changed because the reels 3L, 3C, and 3R cannot start rotating smoothly after the setting values are changed.

  In contrast, when the slot machine 1 is activated regardless of whether or not the setting value has been changed, that is, whether or not the slot machine 1 has been activated with the setting key switch 92 turned ON, the stepping motor step is performed. The counter value for counting the numbers may be initialized so that each excitation phase of the stepping motor is always excited in the initial pattern. In this case, the reels 3L, 3C, and 3R behave the same immediately after activation regardless of whether or not the setting value is changed, so that the player is informed that the setting value has been changed. Can be prevented.

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

  In the control method, when the operation of the stop button 12L, 12C, 12R is detected, the corresponding reels 3L, 3C, 3R are 190 milliseconds from the currently displayed symbol (the right reel 3R during the challenge bonus). Within 75 milliseconds) (within the range of 5 frames in total including the displayed symbol and the amount of pull-in (2 frames for the right reel 3R during the challenge bonus)) Then, it is determined whether or not there is a winning symbol for which the winning flag is set.

  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 peripheral portion, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, a device that virtually displays a symbol on a display device such as a liquid crystal display device may be used instead of the variable display device 2 described above.

  In the above-described embodiment, the slot machine to which medals are applied as a game medium used for setting the number of bets and giving game value associated with winning is described as an example. However, the slot machine embodying the present invention may be a slot machine (so-called parrot) to which a game ball used in a pachinko gaming machine is applied as a game medium. When a game ball is used as a game medium, for example, one medal can correspond to five game balls. Then, the number of game balls required for setting the number of bets per game is 15. However, the number of payouts less than the number of bets (one combination A in the above embodiment). The number of payout game balls in (corresponding to -D) does not necessarily correspond to 5 game balls for one medal. For example, when a winning combination corresponding to one winning combination A to D in the above embodiment is won, only one game ball can be paid out.

  In a so-called parrot, game balls used as game media are stored in a storage tray in the same physical form, and when the player operates the BET button, the game balls stored in the storage tray (upper plate) are stored. The number of game balls corresponding to the BET operation is taken into the parrot via a predetermined take-in route. The number of bets for playing one game is set by the game balls taken inside.

  In addition, when the player operates the checkout button in the parrot, if the bet number has already been set (except when the bet number is automatically set after the replay win), it depends on the set bet number. A number of game balls are discharged to the lower pan provided at the bottom of the slot machine. If the bet number is not set (including the case where the bet number is settled first), the game balls stored in the storage tray are discharged to the lower tray through a predetermined route. The lower plate is provided with a hole through which a game ball stored by a player operating a predetermined lever is passed through the lower plate, and the game ball box (so-called dollar box) is placed under the lower plate. If operated, the game ball owned by the player can be easily transferred to the game ball box.
