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 of whether a transition is made between an advantageous gaming state or an unfavorable gaming state for the player 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.

  In addition, in the slot machine of Patent Document 1, in order to prevent a bonus winning immediately when the bonus winning state is still stocked after the bonus gaming state ends, at the time when the bonus gaming state ends. The gaming state is controlled by RT which cannot win a bonus. Bonus winnings are not possible unless this RT is released, but if you have a sweet release condition to create a so-called bonus resort where the game state of the bonus occurs in a short span, a more severe release condition will be prepared accordingly. Must. Therefore, once a strict release condition is selected, the number of games from the bonus end to the next bonus occurrence becomes too large. Moreover, since the conditions for releasing the RT are determined when the bonus gaming state is completed, the player's interest in a new bonus winning is reduced.

  The present invention prevents the player from being dissatisfied with any of the winning display results determined to permit derivation, and the next special gaming state after the special gaming state ends. An object of the present invention is to provide a slot machine that can prevent the player's interest in deriving a new special display result from being suppressed while the number of games until the game is controlled becomes too large.

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 (game control board 101 of game control board 101) for controlling to a specific game state (RT, high pure loss RT) in which the payout rate calculated by the ratio of the expected value of the number of game values to be played CPU 111 (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 role A or bell together with bonus (2) or big bonus (3), win a single role A or bell regardless of the operating procedure of the stop buttons 12, 12C, 12R. (1) When the single bonus combination BD is won together with the big bonus (2) or the big bonus (3), regardless of the operation procedure of the stop buttons 12L, 12C, 12R Win a prize in either one-piece combination B, one-piece combination C, or one-piece combination D. When replaying with a big bonus (1), big bonus (2), or big bonus (3), stop button 12L , 12C, 12R regardless of the operation procedure, won the replay)
The specific gaming state control means includes
Predetermining that the pre-determining means allows the derivation of the re-game display result during a period until a predetermined condition (digestion of 400 games or 120 games of RT) is satisfied after the special gaming state is ended. The first specific gaming state control means (gaming control) that controls to the first specific gaming state (RT) in which the probability that it is not determined that the derivation of the priority display result is permitted is determined to be a predetermined first probability. CPU 111 of substrate 101 (FIG. 5);
In a period after the predetermined condition is satisfied after the special gaming state is ended, the prior determination unit determines that the re-game display result is allowed to be derived with a probability lower than the predetermined probability. Thus, the special display result is determined after it is determined that the derivation of the special display result is permitted because the probability that the derivation of the priority display result is not determined is a second probability higher than the first probability. The second specific game state control means (the CPU 111 of the game control board 101 (FIG. 11)) controls to the second specific game state (high-pure loss RT) in which the number of games required to be derived is less than the first specific game state . 5)).

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, it is determined that the derivation of the winning display result other than the special display result such as the re-game display result or the minority payment display result is determined in a state where the determination to allow the derivation of the special display result is carried over. For example, it may be 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 for which derivation is permitted is derived irrespective 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 for which it is determined that the derivation is permitted is not derived. Thus, it is possible to prevent any dissatisfaction with the player because none of the winning display results for which derivation is permitted can be derived.

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 gaming state includes a first specific gaming state controlled in a period until a predetermined condition is satisfied after the special gaming state is finished, and a second controlled in a period after the predetermined condition is satisfied. There is a specific game state, but in the second specific game state, by determining that the re-game display result is allowed to be derived with a lower probability than the first specific game state, the priority display result may be derived. If it is determined that the probability of not being determined, that is, the derivation of the special display result is permitted, the probability that a game that causes the special display result to be derived is higher than that in the first specific gaming state.

  Therefore, it is determined that the derivation of the special display result is permitted during the first specific gaming state, and a game in which it is not determined that the derivation of the priority display result is permitted, and the special display result cannot be derived. However, if it is controlled to the second specific gaming state, there is a high possibility that a special display result can be derived, and from there, it is possible to control to a new special gaming state with a relatively small number of games. . Thereby, it can suppress that the number of games after a special game state is complete | finished until it controls to the next special game state becomes large.

  On the other hand, in the first specific gaming state that is controlled first after the end of the special gaming state, if it is determined that the derivation of the special display result is allowed without being determined to permit the derivation of any priority display result. For example, the probability that a game capable of deriving the special display result will be low, but it is not completely impossible to derive the special display result while being controlled to the first specific gaming state. Thus, the player's interest in deriving a new special display result can be maintained without diminishing until the special display result is actually derived after the special gaming state is completed.

The slot machine is
The predetermined condition is satisfied when the number of games after the end of the special gaming state reaches a predetermined number of games (400 RT games or 120 games are consumed),
In the slot machine, a specific display result (replay B) different from the special display result is derived as a display result on the variable display device in a period until a predetermined condition is satisfied after the special gaming state ends. Sometimes, the game number changing means (game) for changing the predetermined game number to a game number smaller than the predetermined game number determined before deriving the specific display result (reset the RT game number to 20 games). The CPU 111 and the RAM 112 (FIG. 5) of the control board 101 can be further provided.

In this case, when the predetermined number of games is reached in the first specific gaming state, the second specific gaming state is controlled. When the specific display result is derived in the first specific gaming state, the second specific gaming state is controlled. The predetermined number of games until the game state is controlled is reduced. Thus, when a specific display result in the first specific game state is derived, the second more likely that can be derived a special display該特another display result if it is determined that the permit derivation of results 2 Since the number of games required before being controlled to the specific gaming state is reduced, it is possible to make the player interested in deriving the specific display result.

  The specific display result may be a winning display result different from the re-game display result and the minority pay display result. Alternatively, the specific display result is derived when it is determined that the derivation of the winning display result other than the priority display result is permitted and the winning display result is not derived by the operation procedure of the stop operation means. It is good also as display results other than the winning display result which can be made. Alternatively, the specific display result may be a specific type of regame display result among the multiple types of regame display results when there are a plurality of types of regame display results. Alternatively, the specific display result may be a specific type of minority payment display result among the multiple types of minority payment display results when there are a plurality of types of the minority payment display results.

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.

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) Design 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, certain small payment Display results because it is intended to be included within the priority display result, when the instruction to allow this derivation is determined, a special display results can not be derived in any event . However, certain small payment Display results, since the identification information in a specific variable display portions in common with the identification information of the specific variable display unit in combination with the special display result, only the identification information specifying the variable display unit derived 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 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 when the voltage rises to a level at which the control unit 110 can be activated when the power is turned on to start the control unit 110, and generates a signal periodically output from the control unit 110. When the count is incremented without being cleared based on the reset counter, that is, when the control unit 110 does not operate for a certain time, a reset signal is output to the control unit 110 and the control unit 110 is restarted. .

  The CPU 111 also has a function of updating the numerical value of the specific address in the RAM 112 by timer interrupt processing and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function). The CPU 111 transmits various commands to 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 in accordance with the target stop position, and then the rotor is stopped by three- phase excitation control. 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. 4 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 gaming states controlled by the CPU 111 of the gaming control board 101 include a big bonus as a special gaming state, RT (a normal gaming state in the slot machine 1) as a gaming state other than the special gaming state, and a high purity loss RT. As will be described later in detail, RT and high-pure lose RT have different replay winning probabilities, but the winning probabilities for other combinations 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, single-piece roles AD) and replaying roles (replay A, replay B) that allow 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 465 (whether the bonus is controlled by the regular bonus 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 RT. Here, depending on whether the big bonus (1), the big bonus (2), or the big bonus (3) triggered the control of the gaming state by the immediately preceding big bonus, it is set in the RT immediately after the big bonus. If the number of games to be played (the number of remaining games is set again by winning Replay B during RT. This will be described later) is determined. If it is a big bonus (1) or a big bonus (2), 400 games, big If it is a bonus (3), 120 games are set. In addition, when all of the number of games set in RT are consumed, the gaming state is controlled to high purity loss RT.

  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 combination A, a replay A, or a replay B, regardless of the operation procedure of the stop buttons 12L, 12C, 12R, a big bonus (1), a big bonus (2), or a big The bonus (3) is not won. Even when one winning combination B to D is simultaneously won, regardless of the operation procedure of the stop buttons 12L, 12C, 12R, the big bonus (1), big bonus (2) or big bonus (3) Don't win. In other words, to win the Big Bonus (1), Big Bonus (2), or Big Bonus (3), you win these roles and there is no winning of Bell, Single Role A, Replay A or Replay B. In addition, the condition that there is no simultaneous winning of one-piece combination B to D is necessary.

  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 medal increases by winning the cherry).

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 A is awarded when a combination of “JAC-JAC-JAC” is aligned on any winning line in RT. When winning a replay A, there is no payout of medals, but the next game can be started again without setting the number of bets (that is, the player's medals will not increase or decrease due to the replay A 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 A is won in the internal lottery. Even if the winning of the big bonus (1), big bonus (2) or big bonus (3) is carried over, the winning of the replay A will be given priority as will be described later. (1) Don't win the big bonus (2) or big bonus (3), make sure to win Replay A.

  On the other hand, Replay B is awarded when a combination of “JAC-JAC-Bell” is aligned on any winning line in RT. When winning a replay B, as in the case of replay A, there is no medal payout, but the next game can be started again without setting the number of bets. If the player has won Replay B without winning any of the big bonus (1), big bonus (2), or big bonus (3), the remaining number of RT games is set to 20 games. It will be reworked.

  After the Big Bonus based on the Big Bonus (1) or Big Bonus (2) winning is completed, 400 games are set as the initial value of RT, and after the Big Bonus based on the Big Bonus (3) winning is ended, RT 120 is set as the initial value of. Accordingly, the number of remaining RT games is overwhelmingly more than 20 games than when the number of remaining games is less than 20, so the number of RT games is reduced in many cases when winning Replay B. Be made. Only when the number of remaining RT games is less than 20 games, winning the replay B increases the number of RT games.

  If you have won the Replay B in RT without winning any of Big Bonus (1), Big Bonus (2), or Big Bonus (3), the remaining RT game count will be 20 games Therefore, when the number of remaining RT games is 20 games or less, the number of RT games increases. However, since the winning probability of the total of big bonus (1), big bonus (2) and big bonus (3) is approximately 1/100, the number of RT digestion games exceeds 200 games and big bonus (1) It is rare that the big bonus (2) and the big bonus (3) are not won. In addition, since the winning probability of Replay B is approximately 1/100, it is rare that the Replay B is further won among the remaining 20 games set anew. Therefore, regardless of the number of remaining RT games, setting the remaining number of RT games to 20 games by winning a Replay B will not be too disadvantageous for the player.

  Since “JAC” and “Bell” are arranged at intervals of 5 frames or less for any of the reels 3L, 3C, 3R, if the replay B is won in the internal lottery, it 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 replay B is given priority as will be described later. (1) Don't win the Big Bonus (2) or Big Bonus (3), be sure to win Replay B. Here, the replay A and the replay B may be collectively referred to simply as “replay”.

  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.

  Replay A or Replay B by winning Replay A or Replay B with Big Bonus (1) Winning Flag, Big Bonus (2) Winning Flag or Big Bonus (3) Winning Flag carried over in RT or High Pure Loss RT When the winning flag of Replay B is also set in an overlapping manner, control is performed so that the symbols of Replay A or Replay B are preferentially aligned on the winning line. Regardless of the operation procedure of the stop buttons 12L, 12C, 12R, the player will win Replay A or Replay B. In this case, winning the big bonus (1), big bonus (2) or big bonus (3) Absent.

  Here, the reason that the player does not win the big bonus (1), the big bonus (2), or the big bonus (3) without winning the replay A or the replay B is given priority over the replay A or the replay B. When the stop control is performed, the replay A or the replay B is not missed in the respective arrangements of “JAC” and “bell” in the reels 3L, 3C, and 3R. The stop control in which the winning is given priority does not mean the stop control that does not miss the replay A or the replay B. Unlike FIG. 3, if “JAC” and “Bell” are arranged so that the symbol interval is larger than 5 frames, the replay A or replay is also performed in the stop control in which replay A or replay B is given priority. Losing B can occur.

  In RT or high-pure loser RT, winning a bell by winning a bell or a single role A with the big bonus (1) winning flag, big bonus (2) winning flag or big bonus (3) winning flag carried over When the winning flag of the flag and the single-player A winning flag is also set, the bell or the single-player A is preferentially aligned on the winning line as in the case of Replay A or Replay B. Controlled.

  In the RT or high-pure lose RT, 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 The winning flags for the single winning combination B to D are overlapped by simultaneously winning the big bonus (1), the big bonus (2) or the big bonus (3) and the single winning combination B to D. In some cases, control is performed so that the symbols of the single winning combination B, the single winning combination C, and the single winning combination D are preferentially aligned on the winning line.

  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 “JAC” 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 within an interval of 5 frames or less, so the “JAC” template state is maintained regardless of the operation procedure of the stop buttons 12C, 12R. Can be). When the left stop button 12L is finally operated, “JAC” is displayed on the left reel 3L according to the operation timing of “Red 7”, “Blue 7”, and “White 7”. 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 RT or high-pure loser RT, winning a watermelon with the big bonus (1) winning flag, big bonus (2) winning flag or big bonus (3) winning flag carried over will also duplicate the watermelon winning flag When set, control is performed so that “watermelon” is preferentially aligned 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 RT or high-pure loser RT, 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 duplicate the Cherry Winning Flag When 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), the big bonus (2) or the big bonus (3) is won at RT or the high purity loss RT, the gaming state becomes the big bonus. Be controlled.

  When the number of medals paid out to the player in the big bonus exceeds 465, the big bonus ends, but the ended big bonus is triggered by winning the big bonus (1) or the big bonus (2). If it is controlled, the gaming state is controlled to RT in which 400 games are set as the initial state. When the ended big bonus is controlled when the big bonus (3) is won, the gaming state is controlled to RT in which 120 games are set as an initial state.

  As described above, although the number of RT games set immediately after each big bonus, which is controlled in response to winning of the big bonus (1), big bonus (2), or big bonus (3), is different, the gaming state ( The winning probabilities for each combination, etc.) are all the same. When the gaming state is controlled by RT, 20 is set as the remaining number of RT games by winning Replay B during RT. On the other hand, if all the number of games in RT (20 games are set by winning Replay B), the gaming state is big bonus (1), big bonus (2) or Until the big bonus (3) is won, it is controlled to the high purity loss RT.

  When the gaming state is a big bonus, a big bonus medium flag is set in the RAM 112. The number of remaining RT games is counted by an RT counter provided in the RAM 112. Even if a value other than 0 is set in the RT counter, if the big bonus flag is set, the gaming state is not regarded as RT, and the RT counter value is subtracted even if one game is consumed. There is no. In addition, when the high pure loss RT, the big bonus medium flag is not set and the RT counter value is 0.

  Here, the number of remaining games in RT set in the RAM 112 is counted by a counter indicating the number of remaining games in RT. The value of the RT counter is decremented by 1 every time one game is consumed during RT. When winning a replay B in RT, 20 is set as the number of remaining RT games for every winning. The number of games set in the RT immediately after the big bonus is determined depending on which of the big bonus (1), the big bonus (2), and the big bonus (3) is won, so the number of RT games set in the RAM 112 is When winning the big bonus (1), big bonus (2) or big bonus (3), the number of games corresponding to each is set.

  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, Replay A, Replay B Acquired accordingly. 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) Since 0 is registered as the number of determination values for Big Bonus (3) +1 Bonus B to D, Replay A, and Replay B, these winning combinations are not won.

  In addition, in the gaming state of RT or high-pure lose RT, 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 where the winning flag of Big Bonus (1), Big Bonus (2) or Big Bonus (3) is not carried over in RT, High Pure Loss RT, Big Bonus (1), Big Bonus (1) + 1 Bonus B ~ D, Big Bonus (2), Big Bonus (2) +1 Bonus B to D, Big Bonus (3), Big Bonus (3) +1 Bonus B to D are registered as non-zero values. 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 RT or High Pure Loss RT, Big Bonus (1), Big Bonus (2) or Big Bonus (3) is not won, so Big Bonus (1), Big Bonus (1) + 1 Bonus B to D, Big Bonus (2), Big Bonus (2) + 1 Bonus B to D, Big As the number of determination values of bonus (3), big bonus (3) +1 sheet combination B to D, 0 is registered, and these combinations are not 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.

  In the RT gaming state, the winning of the big bonus (1), big bonus (2) or big bonus (3) is carried over, and the bell, watermelon, cherry, one-player roles B to D (big bonus (1 ) +1 sheet combination BD, big bonus (2) +1 sheet combination BD or big bonus (3) +1 sheet combination BD overflows when adding the number of judgment values 1 sheet combination BD When winning Replay A and Replay B, the winning flags for these roles will be the winning flags for Big Bonus (1), Big Bonus (2) or Big Bonus (3). It will be set over again.

  On the other hand, in the gaming state of high-pure loser RT, the winning of big bonus (1), big bonus (2) or big bonus (3) is carried over, and bell, watermelon, cherry, When the number of judgment values of a bonus combination B to D (big bonus (1) +1 bonus bonus B to D, big bonus (2) +1 bonus bonus B to D or big bonus (3) +1 bonus bonus B to D is added (Including the case where only one winning combination B to D is won due to overflow), when winning Replay A, the winning flag of these combinations will be the big bonus (1), big bonus (2) or big It will be set over the winning flag of 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 have won the bell, the number of medals held by the player with one big bonus will increase by 480- (480 ÷ 15) × 3 = 384. .

  RT, Big Bonus (1), Big Bonus (1) + 1 Bonus B ~ in a game that has not won the Big Bonus (1), Big Bonus (2) or Big Bonus (3) D, Big Bonus (2), Big Bonus (2) + 1 Bonus B to D, Big Bonus (3), Big Bonus (3) + 1 Bonus B to D, the number of judgment values is RT, High Pure Loss RT In all cases, the value is the same, but the total is 654.

  When the big bonus (1), big bonus (2) or big bonus (3) is not won in RT or high-pure lose RT, the big bonus (1), big bonus (2) or big bonus ( The probability of winning 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 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, it is set) If the values are 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) and Big Bonus (2), which are controlled by the RT of 400 games immediately after the game state of the game is over, has a small number of single winning judgment values of 18 (one of the winning combinations B to D). The big bonus (3), which is controlled by the RT of 120 games immediately after the big bonus game state ends, is as large as 200 (single winning combination B to D). The number of determination values for simultaneous winning with is as small as 18).

  By registering such a number of determination values, the big bonus (3) to be transferred to the RT of 120 games after the big bonus game state is completed has a high percentage of single winning, and the big bonus game state ends. After that, the big bonus (1) and the big bonus (2) to be transferred to the RT of 400 games have a low single winning ratio.

  Bell, Watermelon, Cherry, Single-Board A, Single-Board BD (Big Bonus (1), Big Bonus (2) or Big Bonus (3)) ), The number of determination values for the big bonus (2) or the big bonus (3) is the same value for both RT and high-pure loss RT, The number of judgment values of the combination A is 40020, and the number of judgment values of the one-piece combination B to D (including the case where the combination is selected as a lottery target at the same time as the big bonus (1), big bonus (2) or big bonus (3)) Among the small combinations, the winning combination is almost one of the one combination A, one combination B, one combination C, and one combination D.

  When one winning combination A or one winning combination B to D is won, regardless of the operation procedure of the stop buttons 12L, 12C, 12R, the single winning combination A, the single winning combination B, the single winning combination C or the single winning combination D However, since the number of medals to be paid out is less than the number of bets set to play one game per game, the medals held by the player in the gaming state of RT or high purity loss RT The number of medals will decrease (as will be described below, the winning probability of replay varies between RT and high-pure loss RT, but the number of medals does not increase or decrease even if the player wins the replay).

  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 total values of the determination values for Replay A and Replay B are 14792 and 8992 for RT and high purity loss RT, respectively. Operation procedure for the stop buttons 12L, 12C, and 12R, including when the big bonus (1), big bonus (2), or big bonus (3) has been carried over when replay A or replay B is won Regardless, you will win Replay A or Replay B. Similarly to Replay A and Replay B, when winning a single combination A or single combination B to D, the big bonus (1), big bonus (2) or big bonus (3) wins are carried over. Including the case, regardless of the operation procedure of the stop buttons 12L, 12C, 12R, a single winning combination A, a single winning combination B, a single winning combination C or a single winning combination D will be won.

  In other words, if you exclude only the games that have won the Big Bonus (1), Big Bonus (2), or Big Bonus (3), and only consider the games that have been won from the previous game, RT, In Loss RT, you may be awarded the Big Bonus (1), Big Bonus (2), or Big Bonus (3) without winning any of the Bell, Single Role A, Single Role BD, and Replay The probability of the occurrence of a game with a chance is 300 / 65536≈1 / 218.5 and 6100 / 65536≈1 / 10.7, 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 a game is reached, 236 / 65536≈1 / 277.7 and 6036 / 65536≈1 / 10.9 for RT and high purity loss RT, 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, this means 218.5 to 277.7 games in RT, and 10.7 to 10.9 games in high-pure loss RT. In RT after the end of the big bonus, when considering the number of games required from the end of the big bonus game state to the winning of the big bonus (3), the average is 318.5 to 377.7 games (however, If the set value is different, the number of these games will be different).

  On the other hand, if the big bonus (3) is not won in the RT after the end of the big bonus, when the gaming state is controlled from the RT to the high purity loss RT, Considering the number of games required to win a prize, the average number of games is 110.7 to 110.9.

  In addition, the average number of games required from winning the Big Bonus (1) or Big Bonus (2) to winning is 327.7 to 416.5 for RT and 16.1 to 16 for the high purity loser RT. That means 3 games. Considering the number of games required from the end of the big bonus game state to the big bonus (1) or big bonus (2) winning in RT after the end of the big bonus, on average 427.7 to 516.5 games It will be. (However, if the set values are different, the number of these games will be different).

  On the other hand, if the big bonus (1) or the big bonus (2) is not won in the RT after the end of the big bonus, when the gaming state is controlled from the RT to the high purity loss RT, Considering the number of games required to win Big Bonus (1) or Big Bonus (2), the average number of games is 116.1 to 116.3.

  Both RT and high-pure loss RT reduce the number of medals held by the player, so it can be said that the game state is disadvantageous for the player, but the big bonus (1), big bonus (2) or big bonus ( If winning 3), it 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 will continue without winning the big bonus (1), big bonus (2) or big bonus (3), the RT is more medal than the high-quality loss RT due to the higher replay winning probability. Decrease in number is reduced.

  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), it ’s less players to win the game (there ’s a lesser reduction in the total number of medals), and the player is better at RT than at RT. It can be said that this is an advantageous gaming state for the player. Furthermore, it is said that the big bonus (3) controlling to the RT of 120 games is more advantageous for the player than the big bonus (1) or big bonus (2) controlling to the RT of 400 games. be able to.

  Also, in RT, if the number of games of the RT (120 games or 400 games) set for each type of big bonus is awarded to Replay B regardless of the number of remaining games, the RT from there Twenty games are set as the remaining number of games. In many cases, the number of RT games will be shortened by winning Replay B, but since the number of shortened games will be played with high-pure loss RT, the number of games will continue as RT Compared with, the expected value of the number of games that are not won for one-player roles A to D or replay is increased, and the chances of winning a prize for the big bonus (1), big bonus (2) or big bonus (3) are increased. .

  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, when the result of the previous game is a win in Replay A or Replay B, 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.

  Also, when the symbol combination of big bonus (1), big bonus (2) or big bonus (3) has been derived, the number of RT games corresponding to the type regardless of the RT counter value so far Is set in the RT counter of the RAM 112 as an initial value, but it does not become RT until the number of payout medals in the big bonus exceeds 465 and the big bonus ends (the big bonus flag is deleted). . When the big bonus ends, the gaming state is controlled to RT by setting a value other than 0 to the RT counter.

  When the big bonus medium flag is not set, the RT counter value is other than 0, and the gaming state is controlled to RT, the RT counter value is decremented by 1 each time one game is consumed. . When winning a replay B while controlled by RT, 20 is set in the RT counter regardless of the value of the RT counter at that time. When the value of the RT counter becomes 0, it is controlled to the high purity lose gaming state.

  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, which is advantageous to the player, can be won relatively easily, that is, the big bonus (3) winning flag is set and other small roles Or it is an effect executed when the winning flag for replay 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 either RT or high-pure loss RT, the received winning status notification command indicates that the big bonus (3) winning flag is set. It is determined whether or not it is set and indicates that 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 the game state of the first big bonus, the big bonus (1) is won in FIGS. 9 (a) and 9 (b), and the big bonus (3) is won in FIG. 9 (c). . In addition, in any of FIGS. 9 (a), (b), and (c), the big bonus (1) +1 winning combination B to D will be controlled in the second big bonus game state. The big bonus (1) based on Also, when the average number of games has passed based on the winning probability of each winning combination, it will not win the bell, 1 winning combination A, 1 winning combination B to C, and replay (and watermelon and cherry).

  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 be a big bonus, and when the total number of payout medals in the big bonus exceeds 465, the gaming state is controlled to 400 games RT. When 100 games are digested with 400 games RT, the big bonus (1) +1 winning combination BD is won.

In the RT, an average of 328 to 417 games are required until the game is lost, and the remaining 300 games of the RT are digested and the gaming state is controlled to the high-quality loss RT. However, if the gaming state is controlled by the high purity loss RT, only 17 games are averaged until the stop buttons 12L, 12C, 12R can be operated by the operation procedure corresponding to the big bonus (1). In short, it is possible to win the big bonus (1) (when a loss occurs, the stop buttons 12L, 12C, and 12B are operated by operating procedures corresponding to either the big bonus (1) or the big bonus (2). It is assumed that whether or not 12R is operated is the same ( hereinafter , the same applies to FIGS. 9B and 9C).

  During the 417 games from the end of the first big bonus game state to winning the second big bonus (1), nearly 80% of the games are 1 player A, 1 player B, 1 Winners of doubles C or singles D and medals decrease by two, most of the rest won regular replays and medals do not increase, and a big bonus (1) + singles BD won In the game until the game, the result when the game is lost in the internal lottery is also lost, so the medal on hand of the player exceeds the number of medals increased by the big bonus controlled based on the winning of the first big bonus (1). The number will decrease.

  In the example shown in FIG. 9B, first, it is assumed that the big bonus (1) is won. When the big bonus (1) is won, the gaming state is controlled to be a big bonus, and when the total number of payout medals in the big bonus exceeds 465, the gaming state is controlled to 400 games RT. In this RT, it is assumed that when 90 games are consumed, Replay B is won once and won, and when 100 games are digested after the end of the first big bonus, Big Bonus (1) +1 winning combination B to D is won. . Here, in the RT, by winning the Replay B once, the RT of the new 20 games is controlled from the winning of the Replay B. That is, the gaming state is controlled to the high purity loss RT in 110 games after the end of the first big bonus.

  In this RT, it takes 328 to 417 games on average before becoming lost, and the remaining 10 games after winning the big bonus (1) + 1 role B to D will be in the gaming state Is controlled to a high purity loss RT. However, if the gaming state is controlled by the high purity loss RT, only 17 games are averaged until the stop buttons 12L, 12C, 12R can be operated by the operation procedure corresponding to the big bonus (1). In short, it is possible to win the big bonus (1).

  Here, the number of medals held by the player will decrease for about 127 games from the end of the first big bonus game state until the new big bonus (1) is won. The amount of reduction of the medal is 3 minutes compared to the amount of reduction of the medal from the end of the first big bonus game state in the example of FIG. 9A until the new big bonus (1) is won. It will be about 1 of this.

  In the example shown in FIG. 9C, first, it is assumed that the big bonus (3) is won. When the big bonus (3) is won, the gaming state is controlled to the big bonus, and when the total number of payout medals in the big bonus exceeds 465, the gaming state is controlled to RT of 120 games. In this RT, it is assumed that when 100 games are consumed after the first bonus, the big bonus (1) +1 winning combination BD is won.

  In the RT, an average of 328 to 417 games are required until the game is lost, and the remaining 20 games of the RT are digested and the gaming state is controlled to the high-quality loss RT. However, if the gaming state is controlled by the high purity loss RT, only 17 games are averaged until the stop buttons 12L, 12C, 12R can be operated by the operation procedure corresponding to the big bonus (1). In short, it is possible to win the big bonus (1).

  In this case, the number of medals held by the player will decrease for about 137 games from the end of the first big bonus game state until the new big bonus (1) is won. The amount of reduction of the medal is 3 minutes compared to the amount of reduction of the medal from the end of the first big bonus game state in the example of FIG. 9A until the new big bonus (1) is won. It will be about 1 of this.

  As described above, in the slot machine 1 according to this embodiment, special bonuses such as the big bonus (1), the big bonus (2), or the big bonus (3) are used as the lottery targets in the RT and the high purity loss RT. There is a re-playing combination called a combination, replay A or replay B, bell, watermelon, cherry, one-piece combination A, one-piece combination B, one-piece combination C or one-piece combination 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 flag for the special bonus, big bonus (1), big bonus (2), or big bonus (3), is carried over from the next game until the actual 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 one of the winning flags of replay A, replay B, 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 flag is set for the single winning combination B to D which is a small combination.

  Here, a winning flag of big bonus (1), big bonus (2) or big bonus (3) is set, and a winning flag of bell, single player A, single player B to D, replay A or replay B is also set. When set, the winning flag of the bell, the single combination A, the single combination B to D, the replay A or the replay B is set regardless of the operation procedure of the stop button 12L, 12C, 12R by the player. The winning combination is won and the big bonus (1), big bonus (2) or big bonus (3) is not won.

  A winning flag of big bonus (1), big bonus (2) or big bonus (3) is set, and a winning flag of any one of bell, one-piece combination A, one-piece combination B to D, replay A and replay B is also set. When not set, it becomes possible to win the big bonus (1), the big bonus (2) or the big bonus (3) according to the operation 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 to RT or high-pure lose RT, when winning a small role, Replay A or Replay B, a big bonus (1), a big bonus (2) or a big bonus (3) Even if it is not possible to win (or very difficult), the small role that has been elected to prevent winning the Big Bonus (1), Big Bonus (2) or Big Bonus (3) , It will not be impossible to win up to Replay A or Replay B. As a result, it is possible to prevent the player from being dissatisfied because the player cannot win any of the winning combinations in the RT or the high purity lose RT.

  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 RT with a different number of games. When all of the RT games have been consumed, the gaming state is controlled to the high purity loss RT.

  The main winning combination to be won with high probability in RT or high-pure loser RT is one-piece combination A or one-piece combination BD. The number of medals to be paid out to the player due to winning of one winning combination A, one winning combination B, one winning combination C or one winning combination D is one to set the number of bets for playing one game. Less than 3 medals required. As a result, the payout rate of medals at RT and high-pure lose RT is less than 1, and when the game state is controlled, the number of medals held by the player will decrease. Therefore, when controlled to RT or high-pure lose RT, it is advantageous for the player to win the big bonus (1), big bonus (2) or big bonus (3) as soon as possible.

Here, RT has a high probability of winning Replay A and Replay B, and loses any of Bell, Single Role A, Single Roles BD, Replay A and Replay B (Furthermore, watermelon or cherry The probability of being lost) is low. On the other hand, high purity losing RT is not winning the winning probability is low (high purity loss RT the replay B replay A than RT, lower than winning probability combined total of the replay A and replay B in RT ), The probability of being lost in any one of the bell, the one-piece combination A, the one-piece combinations B to D, and the replay A (further, the watermelon or cherry is also lost) is higher than the RT.

  Therefore, during RT, Big Bonus (1), Big Bonus (2) or Big Bonus (3) has been won, and Bell, Single Role A, Single Role BD, Replay A and Replay B In any game that loses (and also loses watermelon or cherry), even if you cannot win the big bonus (1), big bonus (2) or big bonus (3), If it is controlled by pure loss RT, there is a high possibility that a big bonus (1), big bonus (2) or big bonus (3) can be won, and from there, a new big bonus is controlled with a relatively small number of games. It becomes possible. Thereby, it can be suppressed that the number of games from the end of the big bonus until it is controlled to the next big bonus becomes too large.

  On the other hand, in the RT that is controlled first after the end of the big bonus, any one combination A, one combination B to D, replay A, and replay B are lost (in addition, the watermelon or cherry is lost). And a big bonus (1), big bonus (2), or big bonus (3) winning game is unlikely to occur, but while controlled by RT, big bonus (1), big bonus It is not completely impossible to win bonus (2) or big bonus (3). As a result, a new Big Bonus (1), Big Bonus (2) or Big Bonus from when the Big Bonus ends until the Big Bonus (1), Big Bonus (2) or Big Bonus (3) is actually won. The player's interest in the winning of (3) can be maintained without diminishing.

  Here, after the end of the big bonus controlled by winning the big bonus (1) or the big bonus (2), it was controlled by winning the big bonus (3) in the RT of 400 games. After the end of the big bonus, each game is controlled to RT of 120 games. In RT, the number of remaining RT games is 20 games regardless of the number of remaining RT games so far due to Replay B winning, and in many cases the number of RT games is reduced.

  That is, even if the big bonus controlled by winning the big bonus (1), big bonus (2), or big bonus (3) is the same, the number of RT games controlled thereafter is different. This is because the RT of 120 games, which was controlled by winning the Big Bonus (3), which can digest the number of games faster, was triggered by the winning of the Big Bonus (1) or Big Bonus (2). As a result, it is possible to newly win the big bonus (1), the big bonus (2), or the big bonus (3) with a smaller number of games than the controlled RT of 400 games.

  Thereby, the player can be made to pay attention to the type of the big bonus that is the trigger of the big bonus winning, which determines the number of RT games immediately after the big bonus. Further, in many cases, the player can be interested in whether or not to win a replay B that can reduce the number of RT games. In addition, even if it is controlled to RT of 400 games triggered by winning the big bonus (1) or big bonus (2), the number of RT games is often shortened by winning Replay B. The number of RT games can be digested earlier, and the big bonus (1), big bonus (2), or big bonus (3) won during the high-quality loss RT (you can win faster than during RT) Since it can be expected, the player can be interested in whether or not to win Replay B.

  In RT or high-pure lose RT, the big bonus (1), big bonus (2), or big bonus (3) may be won simultaneously with one-piece combination B to D. There may be cases where a single winning is not performed simultaneously with any combination including B to D. 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, the player can immediately win the big bonus (1), the big bonus (2), or the big bonus (3) in the winning game.

  As described above, in RT or high-pure lose RT, there is a game in which a big bonus (1), a big bonus (2) or a big bonus (3) is won independently without being simultaneously won with other roles. Judging from the effects such as effects, even if it is considered that none of the big bonus (1), big bonus (2) and big bonus (3) has been won by the previous game, the big bonus (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 (3). Is higher than the big bonus (1) and 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. When the number of digested games after the game state of the game is over is relatively small (compared to the case of winning the big bonus (1) or the big bonus (2)), the big bonus (3) can be won. .

  When the gaming state is controlled to the big bonus by winning the big bonus (3), after the total number of RTs of 120 games after the end of the big bonus, the game is controlled to a new big bonus compared to the RT. The high-pure loser RT with a small number of games is controlled earlier than the 400-game RT triggered by the big bonus (1) or big bonus (2). Since the number of games required before a loss occurs in the high-pure loss RT, a new big bonus (1), big bonus (2), or big bonus (3) is won out of a relatively small number of games. And can be controlled to a big bonus game state. 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.

  As a result, when the big bonus (3) is won, the RT or the high purity loser RT is finished 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 played. The 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 until then, it will be 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.

  By the way, in a game in which a single winning combination A, a single winning combination B to D, a replay A, a replay B (RT only), or a bell is won in RT or a high-pure lose RT, the player determines how the stop buttons 12L, 12C. , 12R will not win the big bonus (1), big bonus (2) or big bonus (3). However, even if it is a game that has not won a single-player role A, single-player roles B to D, replay A, replay B (RT only), or a bell in RT or high-pure loser RT, a big bonus before that game If (1) Big Bonus (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 the RT or the high purity loss RT, is the big bonus (1), the big bonus (2), or the big bonus (3) won? The type of the notice effect (including none) is determined at different probabilities depending on whether or not, 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, all of the big bonus (1), the big bonus (2), and the big bonus (3) may be won alone or in the case of winning a single combination BD. However, the ratio of single winning or simultaneous winning was different for big bonus (1) or big bonus (2) and big bonus (3). That is, the big bonus (3) to be transferred to the RT of 120 games after the big bonus game state is ended has a high percentage of single winning, and the big bonus to be transferred to the RT of 400 games after the big bonus game state is ended. In (1) and Big Bonus (2), the percentage of single winners was low.

  On the other hand, Big Bonus (3), which is transferred to the RT of 120 games after the Big Bonus game state is finished, has a low single-winning ratio, and is transferred to the RT of 400 games after the Big Bonus game state is finished. The big bonus (1) and the big bonus (2) to be made may be high in the percentage of single winning.

For example, as shown in the game state by winning combination table of FIG. 10, RT, still a big bonus in high purity Nope RT (1), and have you in the game that are not winning the big bonus (2) or a big bonus (3) The determination value number of big bonus (1) or big bonus (2) to be controlled by RT of 400 games after the end of the big bonus game state is as large as the determination value number of single winning 200 (one-player combination B) The number of judgment values for simultaneous winning with ~ D is as small as 18), and Big Bonus (3), which is controlled by RT of 120 games after the big bonus game is over, has a small number of judgment values for single winning as 18 (1 piece) The number of determination values for simultaneous winning with the roles B to D may be as large as 200).

  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 flag of the other small role, Replay A or Replay B is not set. Alternatively, when the winning flag of another small role, Replay A or Replay B is not set, not only when the winning flag of Big Bonus (3) is set, but also Big Bonus (1) or Big Bonus (2 ) May also be executed when the winning flag is set. Of course, only when the big bonus (3) winning flag is set and the winning flag of any other small role, Replay A or Replay B is not set, the one that executes the special effect is not excluded. Absent.

  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 digested games after the end of the game state of the big bonus increases, it is expected that the winner will be a big bonus (3) with a transition to 120 RTs that is advantageous to the player Will be able to. 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, after the big bonus is ended by winning the big bonus (1) or the big bonus (2), it is controlled to RT of 400 games, and after the big bonus by winning the big bonus (3) is finished, 120 It was supposed to be controlled by game RT. However, compared to RT, a special game that will be controlled with a small number of games in a high-quality loss RT that can win big bonus (1), big bonus (2), or big bonus (3) with a small number of games. The number of types of combination may be larger than the number of types of special combination that will be controlled over a large number of games in the RT. For example, after the big bonus by winning the big bonus (1) is finished, it is controlled to RT of 400 games, and after the big bonus by winning the big bonus (2) or big bonus (3) is finished, it is controlled to RT of 120 games. It is good also as what to do. In this case, the probability of single winning with respect to the big bonus (2) and the probability of simultaneous winning with the single combination BD can be set in the same manner as with the big bonus (3).

  In the above embodiment, the number of RT games after the end of the big bonus is determined by any one of the big bonus (1), the big bonus (2), and the big bonus (3) that are the triggers for winning the big bonus. The game state is controlled to high-quality loss RT after each RT game is set and all of the RT games have been consumed (20 games if the number of games has reached 20 due to Replay B winning). It was. Of course, the game state is controlled from RT to high-pure lose RT by deriving a specific symbol during the RT as well as controlling the game state to the high-pure lose RT based on the total number of RT games. Good.

  In this way, for example, a rare replay (for example, “JAC-Bell-JAC” symbol combination) different from the above-mentioned replay A and replay B is applied as a symbol for controlling the gaming state from RT to high-pure lose RT. can do. If the high-pure loss RT symbol is a symbol that is not missed by the operating procedure of the stop buttons 12L, 12C, and 12R as in rare replay, the winning probability is the number of RT games controlled after the end of the above big bonus. The reciprocal of can be about. The RT controlled after the Big Bonus based on the Big Bonus (1) or Big Bonus (2) winning and the RT controlled after the Big Bonus based on the Big Bonus (3) winning are high. Separate RTs having different winning probabilities for the pure loss RT symbol may be used (however, the winning probabilities for the entire replay are the same).

  As a trigger for controlling the high-pure loser RT, when using both the digestion of a predetermined number of games in RT and the derivation of the high-pure loser RT symbol, the RT is controlled when RT is not considered for the Replay B winning. Set after the end of the big bonus so that the expected value of the number of games until the high-pure-losing RT is controlled is equal to the number of RT continuous games (400 games or 100 games) in the above embodiment. The number of RT games to be played and the derivation probabilities of high-pure loser RT symbols may be determined respectively.

  In addition, during RT, if any of the big bonus (1), big bonus (2), or big bonus (3) is already won, even if the high pure loss RT symbol is derived, the high pure loss RT Even if it is not controlled, if a high pure loss RT symbol is derived regardless of the winning of the big bonus (1), big bonus (2) or big bonus (3), it is controlled to the high pure loss RT. It may be a thing. It is assumed that the gaming state is controlled from RT to high-pure loss RT by using all RT games. In the case of using both the digestion of a predetermined number of games and the derivation of a high-pure loser RT symbol, if the big bonus (1), big bonus (2) or big bonus (3) is won, The high purity loss RT may be controlled only by digestion.

  In the above embodiment, when the big bonus (3) winning flag is set when the special effect is not yet executed at RT or high purity loss RT, any other small role, replay A Alternatively, the special effect is executed only when the winning flag of Replay B is not set. 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 RT or high purity loss RT, the winning flag of big bonus (1), big bonus (2) or big bonus (3) and / or 1 In a game in which the winning flags of the combination of roles B to D are set, the roll 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 RT or high purity loss RT, the winning flag of big bonus (1), big bonus (2) or big bonus (3) and / or 1 In the game in which the winning flags of the combination B to D are set, the turning effect is executed, and the execution timing of the turning effect is the timing when the winning status notification command is transmitted to the effect control board 102, that is, the player However, 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 expectations for winning the Big Bonus (1), Big Bonus (2) or Big Bonus (3) can be enhanced more effectively. Can be improved.

  In the above embodiment, when the special effect is not yet executed at RT or high-pure loss RT, depending on whether the big bonus (1), big bonus (2) or big bonus (3) is won. To perform a notice effect. 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 at RT or high purity loss RT, and any other small role, replay A or replay B is won. The CPU 121 of the effect control board 102 determines that the flag is not set based on the winning status notification command, and the special effect is executed under the control of the CPU 121 of the effect control board 102.

  However, the big bonus (3) winning flag is set when the special effect is not yet executed at RT or high purity loss RT, and the winning flag of any other small role, Replay A or Replay B is also set. The CPU 111 of the game control board 101 determines that there is no freezing effect that disables the progress of the game for a certain period of time (for example, even if the start lever 11 is operated and a predetermined minimum time has elapsed for one game, It is also possible to execute an effect that still does not start the rotation of the reels 3L, 3C, 3R. While the freezing effect is being executed under the control of the CPU 111 of the game control board 101, the big bonus (3) winning flag is set, and any other small role, Replay A or Replay B winning flag is also set. The CPU 121 of the effect control board 102 may determine that there is no winning situation notification command and execute an effect linked to the freeze effect.

  In the above embodiment, the main small role in the RT and the high purity loss RT is a single role A in which only one medal is paid out by winning, or a single role B, a single role C, or a single role D By setting these as the main small roles, the number of medals held by the player is reduced in the gaming state of RT and high purity loss RT. However, if the number of medals held by the player can be reduced as a whole in the gaming state of RT and high-pure lose RT, only two medals less than three bets set for one game are paid out. It is also possible to use the two-piece role 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 paid-out medals exceeds 465 regardless of whether the big bonus (1), the big bonus (2), or the big bonus (3) is won. (Only the number of RT games controlled immediately after the end of the big bonus was different), but won either the big bonus (1), big bonus (2) or big bonus (3) Depending on how, the upper limit of the number of payout medals may be controlled to a different big bonus.

  For example, when winning a big bonus (1), the bonus is controlled on the condition that the total number of medals paid out exceeds 465, and the RT is controlled to 400 games after the end of the big bonus. However, when winning the big bonus (3), it is controlled to a big bonus that ends on condition that the total number of medals paid out exceeds 405, and after that big bonus ends, it is controlled to RT of 120 games. It may be a thing. 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 the 400-game RT controlled after the big bonus game state is ended based on the winning of the big bonus (1), the RT is disadvantageous as compared to the high-pure lose RT, so that it is controlled to be longer. Until the big bonus (1), big bonus (2) or big bonus (3) is won, the number of games is larger than the 120 games RT controlled based on the big bonus (3) winning. In other words, the expected value of the decreased number of medals until that time is still larger than the expected value of the increased number of medals with the previously controlled big bonus.

  On the other hand, in the 120-game RT controlled after the big bonus game state is ended based on the big bonus (3) winning, the game is controlled to a high-pure loss RT that is advantageous compared to the RT, so that the big bonus (1) It is possible to win the big bonus (2) or the big bonus (3) with a smaller number of games than when controlled by the RT of 400 games, and the expected value of the reduced number of medals is the big bonus ( More than the expected value of the number of medals to be reduced until the next big bonus (1), big bonus (2), or big bonus (3) is awarded after the big bonus controlled based on the winning of 1) ends. Small enough. 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 number of reduced medals in the RT after the end of the big bonus game state and the high-pure loss RT.

  In the above embodiment, after the end of the big bonus controlled by the big bonus (1) or the big bonus (2), the RT of 400 games is changed to the big bonus controlled by the big bonus (3). After the end, 120 games were assumed to be controlled by RT. In addition, if all the RT games are consumed, the gaming state is controlled to the high-quality loss RT.

  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 either RT or high purity loss RT is determined in advance. It is good also as what controls. When the data in the RAM 112 is initialized when the power of the slot machine 1 is turned on (which may or may not be accompanied by a change in the setting value), either RT or high purity loss RT is determined 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. Thus, it was intended to prevent that the reels 3L after changing settings, 3C, that 3R is smoothly change the setting value to scratches rotation start would be perceive the player.

  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 align.

  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.
