Description

  The present invention relates to a slot machine, and in particular, to a special game state that continues until the number of awarded game values reaches a special prescribed number or until it is determined that derivation of a special display result is permitted, and derivation of a special display result. And a specific gaming state controlled on the condition that it is determined that the game is permitted.

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

The types of winning combinations (combinations of symbols) are as follows: a small role with the addition of a gaming value such as a medal, and a game without using a gaming value such as a medal to set the number of bets for the next game. There are replays (replays) that can be started, and special roles (bonuses) with a game state advantageous to the player, such as regular bonuses and big bonuses.
These winning combinations are controlled such that, when one of the winning combinations is won in the internal lottery performed at the start of the game, the winning combinations on a plurality of reels are aligned, and the winning combinations in the internal lottery are aligned. In general, a prize is generated so as to be controlled according to the winning combination according to the winning combination.
It is necessary to control the reels constituting these variable display devices so that the winning combinations in the internal lottery are aligned as described above, and to control the unwinning roles to be aligned. These reels are often driven by a stepping motor because they must be stopped accurately (for example, see Patent Document 1).

  On the other hand, in a game store that operates with slot machines installed, it is necessary to change the stage of the winning probability of the installed slot machines in order to adjust sales, so this type of slot machine is A function is provided for selecting and setting a set value, which is a value indicating the stage of the winning probability applied as the lottery probability of the internal lottery, from a plurality of values for which different probabilities are determined by an operation of an employee or the like. Further, the operation of changing these set values also has a function of resetting the control state up to that time, and the operation of changing the set values causes the data in the work memory of the microcomputer that controls the game to be initialized. (For example, see Patent Document 2).

In another aspect of the slot machine,
A variable display device that enables a game to be started by setting a predetermined number of bets for one game using a game value (medal), and variably displays a plurality of types of identification information each of which can be identified. In the slot machine (slot machine 1) in which one game is completed when the display result is derived on the (variable display device 2) and a prize can be generated according to the display result derived on the variable display device,
Before the display result of the variable display device is derived for each game, a plurality of types including a small display result (watermelon, bell, cherry) and a special display result (single bonus) accompanied with the addition of the gaming value are provided. Predetermination means (step S103) for determining whether or not to derive a winning display result of
When a predetermined special transition condition (challenge of the challenge bonus (1) or the challenge bonus (2)) is established, a special game state that controls the game state to a special game state (challenge bonus) that is more advantageous to the player than the normal game state. Game state control means (steps S208 and S210);
Stop operation means (stop buttons 12L, 12C, 12R) operated by a player to stop the change display of the identification information;
Derivation control means for causing the variable display device to derive a display result according to the determination result of the pre-determination means and the operation procedure of the stop operation means (step S104 (in the case of a challenge bonus, watermelon, bell , Set the cherry winning flag)),
At least in the special game state, it is determined that the derivation of the special display result is permitted (RT symbol derivation due to missing of the single bonus winning), and the game is performed more than the normal game state different from the special game state. Specific game state control means (step S216) for controlling the game state to a specific game state (RT) advantageous to the player,
The small combination display result includes a first small combination display result (cherry) accompanied by a predetermined number (two pieces) of gaming values and a larger number (15 pieces) of gaming pieces than the first small combination display result. Including the second small role display result (watermelon) accompanied by the addition of value,
The special game state control means controls the special game state, and then controls the special game number until the game reaches a special prescribed number (30 or 150) greater than the predetermined number, or The game state is controlled to the special game state until the game (single bonus win) determined to permit the derivation of the special display result by the advance determination means (step S305 (the value of the CB counter is determined by the single bonus win). Is initialized to 0), steps S307, S309, and S311 (the challenge bonus ends when the value of the CB counter becomes 0 as a result of the subtraction)),
The derivation control means performs the first procedure (the first operation of the stop button 12L at the timing when the 16th and 17th symbols are located at the lower stage of the left reel 3L) when the special game state is being controlled. When the stop operation means is operated, the first small combination display result is derived, and a second procedure different from the first procedure (at the timing when the symbols 19 to 15 are located at the lower stage of the left reel 3L). When the stop operation means is operated by the stop button 12L being operated first), the second small combination display result is derived.

In the slot machine of another aspect, the game state is controlled to the special game state by the establishment of the predetermined special transition condition, but in this special game state, the operation procedure of the stop operation means regardless of the determination of the predetermined means. Can be derived in accordance with the result.
More specifically, if the stop operation means is operated in the first procedure, the first small combination display result to which a predetermined number of game values are given is increased, and if the stop operation means is operated in the second procedure, the result is increased. The second small role display result to which the gaming value is given can be derived. Then, when the cumulative value of the gaming value provided in the special game state reaches the special prescribed number due to the derivation of the small combination display result, the special game state is ended.

  In addition, the special game state is ended only for the game when the predetermination means determines that the derivation of the special display result is permitted. Here, assuming that the cumulative number of game value grants reaches the special prescribed number and the special game state is terminated without determining that the derivation of the special display result is permitted, the first small game is performed in each game during that time. In the case of deriving the combination display result, the number of games to be consumed in the special gaming state is larger than in the case of deriving the second small combination display result. As the number of games to be consumed increases, the probability that it is determined that the derivation of the special display result as the whole special game state is permitted increases.

  The special game state which is advantageous to a player different from the special game state is controlled at least on condition that it is determined that the derivation of the special display result is permitted in the special game state. . In other words, in the special game state, the operation of the stop operation means in the first procedure to derive the first small combination display result, and increasing the number of games consumed in the special game state is a chance to be controlled to the specific game state. Will be higher. As described above, in the above-mentioned slot machine, the technical intervention of the player works for the control to the specific game state, so that the interest of the game can be improved.

  On the other hand, in the special game state, the stop operation means is operated in the second procedure to derive a second small winning combination display result having a large number of game values, and the number of games consumed in the special game state is reduced. , The number of gaming values used for setting can be reduced, so that the profit obtained by the player is increased when only the special gaming state is considered. For this reason, even if the chance of being controlled to the specific game state decreases, the special game state alone can provide a great profit in a short period of time, or increase the chance of being controlled to the specific game state to increase the special game state to the specific game state. Since there is an option in the game to obtain a large profit over a long period of time, the game becomes very strategic and the interest of the game can be further improved.

In another aspect of the slot machine,
When it is determined that the derivation of the special display result is permitted, the derivation control means presses the stop button 12L at a timing when the symbols 10 to 13 are located at the lower stage of the left reel 3L. The special display result is derived on condition that the stop operation means is operated in the first operation), and a specific procedure different from the special procedure (the 17th and 18th symbols are displayed at the lower stage of the left reel 3L). When the stop operation means is operated with the stop button 12L operated first at the timing of the position), a specific display result (RT symbol) different from the winning display result is derived,
The specific game state control means may control a game state to the specific game state when the specific display result is derived (step S216).

  In this case, the player's technical intervention acts not only to increase the chance of being controlled to the specific game state but also to actually control the game state to the specific game state. Can be improved.

Here, the above slot machine
In the special game state, when it is determined that the derivation of the special display result is permitted, a notification unit (the liquid crystal display 4, the CPU 121 (modification)) for notifying information that can specify the determination is further provided. It may be.

  In this case, if it is assumed that the first procedure and the specific procedure are mutually exclusive, the first procedure is performed in the special game state to increase the chance that the player is controlled to the specific game state. Even when the stop operation means is operated, when it is determined that the derivation of the special display result is permitted, the operation can be switched to the operation in the specific procedure for controlling the game to the specific game state.

Or, here, in the above slot machine,
The first procedure is at least partially overlapped with the specific procedure (more preferably, included in the specific procedure) (when the left stop button 12L is operated first, the cherry The winning timing and the timing at which the RT symbol can be derived are the same when the 17th and 18th symbols are located at the lower stage of the left reel 3L), and the derivation of the special display result is allowed in the special gaming state. The information that can specify that the action to be performed is determined may not be notified.

Further, when at least a part of the first procedure and the specific procedure overlap,
The derivation control means operates the stop operation means in an overlapping procedure of the first procedure and the specific procedure when it is determined that the derivation of the special display result is permitted in the special game state. It is possible that both the first small combination display result and the specific display result are led out to the variable display device on the condition that the first small combination display result and the specific display result are displayed. When the stop button 12L is operated first at the timing of the position, the RT symbol is derived simultaneously with the winning of the cherry.

In this case, even if the player is not informed at all that it has been determined that the derivation of the special display result is permitted, the special game state is set to increase the chance of being controlled to the specific game state. If the stop operation means is operated in one procedure, the same operation procedure can be continued to derive the specific display result, and the specific gaming state can be controlled to the gaming state.
Furthermore, if it is possible to derive both the first small combination display result and the specific display result, the player may be attracted to the first small combination display result and the special display result may be derived. It is possible to make it difficult for the player to notice that the determined special game state has ended.

Also, in this case, the slot machine
When the special display result is derived, a special game state control unit (step S212) that controls a game state to a special game state (single bonus) different from any of the normal game state, the special game state, and the specific game state. ) May be further provided.
Here, the expected value of the game value obtainable by the player in the specific game state may be larger than the expected value of the number of game values obtainable by the player in the special game state. (FIG. 17B) (In the single bonus, the number of judgment values of the bell only increases by one from the normal game state, whereas in the RT, the number of judgment values of the replay changes from 8992 in the normal game state to 50604. The increasing state continues for 300 games)).

  In this case, when it is determined that the derivation of the special display result is permitted, the special display result can be directly derived and the gaming state can be controlled to the special game state. Deriving and controlling the gaming state to the specific gaming state will give the player more benefits, so the technical intervention to dare to drop the special display result decided to allow the derivation It will be interesting.

In another aspect of the slot machine,
The derivation control means stops changing display of the identification information within a predetermined delay time (maximum stop delay time) from the operation of the stop operation means, and is controlled to the special game state. In some cases, the predetermined delay time may be reduced to a special delay time (75 milliseconds) shorter than the normal delay time (190 milliseconds) applied in a game state other than the special game state. The maximum stop delay time of the left reel 3L is reduced to 75 milliseconds).

  In this case, even if it is possible to derive the small combination display result regardless of the determination of the pre-determination means when controlled to the special game state, the special delay time range shorter than the normal delay time If the first small hand display result and the second small hand display result are separately targeted, the stop operation means is operated so that each can be derived within the range of the special delay time. There must be. For this reason, the technical intervention of the player in the special game state is further enhanced, and the interest of the game can be further improved.

  Further, in the case where the predetermined means determines whether or not to permit derivation of a replay display result (replay) accompanied with replay as the plurality of types of prize display results, the specific game state For example, a re-game high probability state (RT) that sets the probability that the pre-determination means determines to permit the derivation of the re-game display result to be higher than the normal game state (FIG. 17 ( b)).

In another aspect of the slot machine,
The variable display device may change and display identification information arranged in a predetermined arrangement (FIG. 2),
The first procedure is to stop the stop operation means at a timing when identification information included in a first range of the predetermined arrangement is located at a predetermined position of the variable display device while the identification information is variably displayed. (The stop button 12L is operated first at the timing when the 16th and 17th symbols are located at the lower stage of the left reel 3L), and the second procedure is a second operation different from the first range. The stop operating means may be operated at the timing when the identification information included in the range is located at the predetermined position (the stop button 12L is operated at the timing when the symbols 19 to 15 are located at the lower stage of the left reel 3L). First). In this case,
It is preferable that the number of pieces of identification information included in the first range is smaller than the number of pieces of identification information included in the second range (2 frames and 18 frames, respectively).

  In this case, operating the stop operation means in the second procedure is more difficult than operating in the first procedure. It is more difficult to increase the chances of being controlled and to obtain profits from the special game state to the specific game state as a whole. As described above, when it is selected to obtain a profit over a long period of time rather than to obtain a simple profit in a short period of time, the difficulty of technical intervention is increased, so that the interest of the game can be further improved. .

In another aspect of the slot machine,
The variable display device may change and display identification information arranged in a predetermined arrangement (FIG. 2),
The derivation control means identifies a predetermined range in the predetermined arrangement that can be derived until a predetermined delay time (75 milliseconds for the left reel 3L) elapses from the operation of the stop operation means in the special game state. Information for stopping the derivation of the special display result in the special game state, the special identification information (left The special display result is derived on condition that the reel includes the "BAR" of the reel 3L), and a display result different from the special display result is obtained when the predetermined range does not include the special identification information. It may be. In this case,
The special identification information in the predetermined arrangement is arranged at intervals that include a greater number of pieces of identification information than the number of pieces of identification information included in the predetermined range (total of two frames including the number of sliding frames of one frame). Preferably, only one “BAR” is arranged on the left reel 3L, that is, arranged at intervals of 20 frames.

  In this case, even if it is determined that the derivation of the special display result is permitted, it is difficult to derive the special display result as the display result of the variable display device. It is possible to make it difficult for the player to detect that the gaming state has been ended.

  Note that the variable display device includes a plurality of variable display units, and a delay time from the operation of the stop operation unit to the stop of the identification information in the special game state is different for each variable display unit (for example, a plurality of variable display units). If the delay time in the special variable display unit is shorter than the normal delay time and the delay time in the variable display units other than the special variable display unit remains the normal delay time, the predetermined delay The size of the predetermined range in the predetermined array that can be derived until the time elapses also differs.

  Here, some variable display units, for example, only the special identification information in the array of the special variable display unit includes a larger number of pieces of identification information than the number of pieces of identification information included in the predetermined range corresponding to the special delay time. May be arranged at an interval. Alternatively, the special identification information in each array of all the variable display units is arranged at intervals including a larger number of pieces of identification information than the number of identification information included in a predetermined range corresponding to each variable display unit. May be used.

In another aspect of the slot machine,
The special game state is a first special game state (a challenge bonus (Challenge Bonus (Challenge Bonus)) that is controlled until the cumulative value of the provided game value reaches the first special prescribed number (30) after the special transfer condition is satisfied. 1) a challenge bonus controlled by winning, and a second special prescribed number (150 cards) in which the cumulative value of the gaming value provided after the special transition condition is satisfied is larger than the first special prescribed number. ), A second special game state (a challenge bonus controlled by winning the challenge bonus (2)).

  Here, the special provision number which is the end condition of each special game state is different depending on whether it is controlled to the first special game state or the second special game state. If the same type of small combination display result is derived for each game, the number of games that can be executed in each special game state will differ. Then, the probability that it is determined that the derivation of the special display result is permitted before reaching the special prescribed number is terminated is different between the first special game state and the second special game state, and the specific game state is determined. Since there is also a difference in the number of chances of being transferred to the game, it is possible to further enhance the interest of the game.

Here, the pre-determining means is means for deciding that derivation of a first special display result (challenge bonus (1)) accompanied by transition to the first special gaming state is allowed as the winning display result. , And means for determining that derivation of a second special display result (challenge bonus (2)) accompanied by a transition to the second special game state is permitted,
The special game state control means controls the game state to the first special game state when the first special display result is derived, and the second special display state when the second special display result is derived. The game state may be controlled to the game state.

  In this case, it is controlled to one of the first special game state and the second special game state depending on which of the first special display result and the second special display result is derived as the display result of the variable display device. Is determined, so that it is easy for the player to understand what special game state is to be controlled.

  Note that the first special game state and the second special game state differ only in the special number that is the end condition when the permission to derive the special display result is not determined. May be exactly the same.

In another aspect of the slot machine,
The specific game state control means does not end the specific game state even if the special transition condition is satisfied in the specific game state (Steps S208, S210 (Challenge Bonus (1), Challenge Bonus (2) , The value of the RT counter is not cleared)), and the game state can be controlled to the specific game state until the number of digested games in the specific game state reaches a predetermined game number (300 games) (step S216). (At the time of deriving the RT symbol, 301 is set as the initial value of the RT counter.)

  The specific game state control means does not end the specific game state even if the special transition condition is satisfied in the specific game state, and controls the game value of the game value provided after controlling the specific game state. The game state is controlled to the specific game state until the cumulative number or the number obtained by subtracting the number of gaming values used for setting the bet amount from the cumulative number reaches a specific prescribed number (modification). You can also.

  In this case, the profit that should be obtained by the player in the specific game state is not lost even when the special transition condition is satisfied, so that the specific game state becomes a more advantageous game state for the player. And since the specific game state becomes a more advantageous game state for the player, the importance of the option of obtaining a profit including the specific game state is more important than simply trying to obtain a profit only in the special game state. That is, the aim of the present invention can be further refined.

In another aspect of the slot machine,
First electronic components (single BET switch 45, MAXBET switch 46, inserted medal sensor 44, start switch 41, stop switches 42L, 42C, 42R, reel sensors 3SL, 3SC, 3SR, A gaming electronic component including at least one of a payout sensor 81) and a second electronic component (reel motor 3ML, 3MC, 3MR, hopper motor 82) to which a signal relating to the progress of the game is input;
At least the above-mentioned control for controlling the progress of a game by being electrically connected to the game electronic component and receiving a signal from the first electronic component and / or outputting a signal to the second electronic component. A game control board (game control board 101) on which a game control means (game control unit 110) including the pre-determination means, the derivation control means and the special game state control means is mounted;
The game electronic component and the game control board are removably connected by connectors (board side connector 620a and cable side connector 610a / board side connector 621a and cable side connector 611a / board side connector 622g and cable side connector 612g). And at least one wiring (cable 601a, 601g) for electrically connecting the gaming electronic component and the gaming control board,
A relay board (operation section relay board 107), which is connected to at least the wiring and the connector, and relays input and output of signals between the game electronic component and the game control board;
The connection between the connectors on the wiring between the game electronic component and the game control board is set to a connection release restricted state in which the connection cannot be released unless the release restriction member relating to the connection between the connectors is destroyed. And a disconnection regulating means (connector regulating members 500 and 650) to be formed.
The connection release restricting means,
The connection (connector between the board-side connector 620a and the cable-side connector 610a / board-side connector 621a and the cable-side connector 611a) of the wiring (cable 601a) between the game control board and the relay board cannot be released. First connection release restricting means (connector restricting member 500);
A second connection release restricting means (connector) for disabling the connection (connector between the board side connector 622g and the cable side connector 612g) of the wiring (cable 601g) between the relay board and the game electronic component; Regulating member 650).

  In this case, not only the connection of the wiring between the game control board and the relay board, but also the release of the connection of the wiring between the relay board and the electronic component for game is restricted, so that the game is controlled. The release of the connection between all the connectors of the wiring provided between the electronic component for game and the game control board is regulated. As a result, it becomes difficult to perform an illegal act such as replacing one of the connectors with a connector such as an unauthorized driving tool and making the game control board illegally input a signal relating to the progress of the game. Implementation can be effectively prevented.

  In addition, since the disconnection restriction state is formed by the disconnection restriction means, the disconnection restriction member must be broken in order to release the connection between the connectors, and the connection is released again after releasing the connection. Since it is extremely difficult and troublesome to form a restricted state, it is possible to more effectively suppress the above-mentioned misconduct. Furthermore, since the disconnection restricting means includes the second disconnection restricting means for disabling the connection between the connectors of the wiring between the relay board and the game electronic component, the illegal use of the game electronic component can be prevented. Signal input / output can also be prevented.

  The relay board may be connected to one or a plurality of game electronic components and a game control board, or may be connected to a plurality of game control boards. It is preferable that a third release restricting means for disabling the connection of the wiring between the connectors between one relay board and the other relay board to be released is provided. Release of the connection between all the connectors of the wiring provided between the game control board and the game control board is restricted.

  FIG. 3 is a diagram showing a configuration of a control circuit of the slot machine 1. As shown, the control circuit of the slot machine 1 includes a power supply board 100, a game control board 101, an effect control board 102, a reel relay board 103, a reel lamp relay board 104, an external output board 105, and an effect relay board 106. It is roughly divided.

  The power supply board 100 transforms an external power supply voltage of AC100V and supplies operating power to the game control board 101 and other parts of the slot machine 1. Although FIG. 3 shows that the game control board 101, the hopper 80, and the switches 91 to 94 are connected only, the power supply board 100 also supplies power to other units. The power supply board 100 is provided inside the slot machine 1 and is connected to a hopper 80 that includes a hopper motor 82 that performs a payout operation of medals and a payout sensor 81 that detects payout of medals.

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

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

  The CPU 111 has an interrupt function (including an interrupt disabling function) such as a time counting function and a timer interrupt, executes a program (described later) stored in the ROM 113, performs processing relating to the progress of the game, and executes processing in the slot machine 1. Each part of the control circuit is controlled directly or indirectly. The processing word of the CPU 111 is one byte, and the addresses of the RAM 112 and the ROM 113 are assigned in units of one 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 the stored contents even when the slot machine 1 is turned off. The RAM 112 is provided with an area for a counter for counting the number of steps of the stepping motors constituting the reel motors 3ML, 3MC, 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 the value each time a pulse is generated, and the sampling circuit 116 acquires the 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 in the progress of the game, and the range of numerical values to be counted for each type of random number is defined. The CPU 111 obtains the numerical value indicated by the random number generation circuit 115 as a random number by sending an instruction to the sampling circuit 116 in accordance with the processing (hereinafter, this function is referred to as a hardware random number function).

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

  The reset circuit 118 activates the control unit 110 by outputting 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. When the value of the reset counter is counted up without being cleared based on the above, that is, when the control unit 110 has not operated for a predetermined 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 a specific address in the RAM 112 by a timer interrupt process and obtaining the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function). The CPU 111 transmits various commands to the effect control board 102 via the I / O port 114. The information (command) is sent from the game control board 101 to the effect control board 102 in only one direction, and the information (command) is not sent from the effect control board 102 to the game control board 101.

  Each 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 content of the control state. When transmitting a command from the game control board 101 to the effect control board 102, the CPU 111 sets the command to be transmitted in the command transmission buffer provided in the RAM 112 in the order of the upper byte and the 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 enough to set a predetermined number of commands. For example, when two commands are transmitted at the same time, the upper byte, the lower byte of the first command, the upper byte, and the lower byte of the second command are set in the command transmission buffer of the RAM 112. The upper byte and the 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 connected to a single BET switch 45, a MAX BET switch 46, a start switch 41, stop switches 42L, 42C, 42R, a settlement switch 47, a first reset switch 48, and a inserted medal sensor 44. Of the switches / sensors are input. Further, detection signals of the reel sensors 3SL, 3SC, 3SR are input via the reel relay board 103. According to the detection signals of these switches / sensors input through the I / O port 114 or the detection signals of various switches input through the power supply board 100 as described above, the CPU 111 on the game control board 101 Processing is in progress.

  The game control board 101 also includes a flow path switching solenoid 49, a payout number display 51, a credit display 52, a payout display 53, an insertion instruction lamp 59, a one bet lamp 54, a two bet lamp 55, and three The betting lamp 57, the game over lamp 63, the start lamp 60, the replay lamp 62, the BET button lamps 70a, 70b, the operation valid lamps 63L, 63C, 63R are connected, and the CPU 111 performs these operations according to the progress of the game. Controlling.

  In addition, reel motors 3ML, 3MC, 3MR are connected to the game control board 101 via a reel relay board 103. The CPU 111 controls the reel motors 3ML, 3MC, 3MR via the reel relay board 103 with reference to a stop control table selected according to a winning flag set in the RAM 112 by an internal lottery described later, and controls the reels 3L, 3C. Stop 3R. 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-wayness of information transmitted from the game control board 101 to the effect control board 102. Even if the effect relay board 106 does not check the game control board 101 or the effect control board 102 by checking this state, an incorrect signal is sent to the control unit 110 of the game control board 101 (particularly, an invalid signal is input to the effect control board 102 from the outside). It is possible to check whether or not a modification has been made such that a signal which is to be input) is input.

  The effect control board 102 is a sub-side control board that controls the execution of the effect in the slot machine 1, and has 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 mounted thereon. I have. The CPU 121 is provided with a random number generation circuit 125 and a sampling circuit 126. The CPU 121 obtains the value counted by the random number generation circuit 125 by the sampling circuit 126, so that the CPU 121 has the same hardware random number function as the game control board 101. Is formed. 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 a process relating 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 backed up by a battery, 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 a control signal 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 the command transmitted from the game control board 101 reaches the I / O port 124, a command reception interrupt occurs for the CPU 121, and the received command is sequentially put into the command reception buffer of the RAM 122 by this command reception interrupt processing. To go. The CPU 121 fetches the command put in the command receiving buffer in units of 2 bytes, and performs processing by determining the type of the command by the upper byte and the content indicated by the command by 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 a plurality of commands at the same time. For this reason, the command receiving buffer of the RAM 122 also has a capacity enough to store a plurality of commands, and the CPU 121 determines that another command has not been received when the processing based on one command extracted from the command receiving buffer is completed. If it is stored in the buffer, the processing based on the next command is performed. The capacity of the command reception buffer of the RAM 122 is larger than the capacity of the command transmission buffer of the RAM 112.

  The game effect lamps 75A to 75M, the liquid crystal display 4, the speakers 7L, 7R, 7U, the fluorescent lamp 6, the weight lamp 61, and the bonus notification lamp 66 are connected to the effect control board 102. The reel lamp 3LP is connected via the reel lamp relay board 104. The control unit 120 of the effect control board 102 controls each of these units to perform an effect.

  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. A full tank sensor 90 is also connected to the reel relay board 103, and a detection signal thereof is input. The full tank sensor 90 is provided inside the slot machine 1 and detects that the medals in the overflow tank for storing medals overflowing from the hopper 80 are full.

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

  The external output board 105 is connected to an external device such as a hall management computer, and receives a signal during a challenge bonus, a signal during a single bonus, a reel control signal, and a stop signal input from the game control board 101 via the reel relay board 103. A switch signal, a medal IN signal, a medal OUT signal, a winning status signal, and a security signal are output to the external device. The signal during the challenge bonus, the signal during the single bonus, the reel control signal, the stop switch signal, the medal IN signal, the medal OUT signal, the winning status signal, and the security signal are output from individual output terminals. Of course, the security signals include a door open signal, a set value change signal, a closing error signal, a payout error signal, another error signal, and a signal during settlement as described later, but these are the same in time division. Output from the output terminal.

  A door open sensor 95 for detecting that the front door is open is mounted on the external output board 105, and a door open signal of the security signals is output based on a detection signal of the door open sensor 95. . The external output board 105 stores power when power is being supplied to the slot machine 1 (that is, when the slot machine 1 is ON), and when the power supply is cut off (that is, when the slot machine 1 is ON). (When 1 is OFF), a backup power supply including a storage battery for supplying the stored power to the external output board 105 is mounted.

  When the power of the slot machine 1 is turned on, the external output board 105 detects that the front door is open by the door open sensor 95 by the power supply from the power board 101, and the front door is opened. A security signal including a door opening signal indicating the presence is output to the external device. On the other hand, when the power of the slot machine 1 is turned off, the external output board 105 detects that the front door is open by the door open sensor 95 by supplying power from the backup power supply, and the front door is opened. And outputs a security signal including a door open signal indicating that the external device is located in the external device. The details of the medal IN signal, the medal OUT signal, and the security signal output from the external output board 105 will be described later.

  Next, the stepping motors constituting the reel motors 3ML, 3MC and 3MR will be described. The stepping motors constituting the reel motors 3ML, 3MC, and 3MR are, for example, hybrid type stepping motors, and include a stator and a rotor opposed thereto. The rotor has a number of gear-shaped projections, into which permanent magnets magnetized in the same direction as the rotation axis are incorporated.

  The stepping motor receives a pulse signal (excitation pulse) from the CPU 111 of the game control board 101, an excitation current flows sequentially through the excitation phases φ1 to φ4 of the stator, and these excitation phases φ1 to φ4 are excited in a predetermined order. Accordingly, the rotor is driven to rotate, and the reels 3L, 3C, 3R are rotated by the rotation of the rotating 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, among the excitation phases φ1 to φ4, the excitation phases for inputting pulse signals are (φ1, φ2), (φ1), (φ4, φ1), (φ4), (φ3, φ4), (Φ3), (φ2, φ3), (φ2), (φ1, φ2)..., And the excitation phase for inputting the pulse signal is alternately repeated as one or two phases. I have.

  As described above, each time a pulse signal for supplying an exciting current to the exciting phases φ1 to φ4 is input, the rotating 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 possible to understand how to switch the excitation phase of the input pulse signal in accordance with the counted rotation step of the stepping motor.

  When the reel sensors 3SL, 3SC, and 3SR detect the reference position with the rotation of the reels 3L, 3C, and 3R, 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 determined by referring to the value of the counter (the number of steps) counted by the rotation step.

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

  FIG. 4 is a schematic diagram showing a wiring connection state between the game control board 101 and a game electronic component connected to the game control board 101. FIG. 4 shows a single BET switch 45, a MAXBET switch 46, which is operated when setting a bet amount, among various electronic components such as switches and sensors connected to the game control board 101, and when starting a game. A start switch 41 which is operated, a stop switch 42L, 42C, 42R which is operated when stopping the rotation of the reels 3L, 3C, 3R, an inserted medal sensor 44 which detects an inserted medal for setting a bet amount; The reel motors 3ML, 3MC, 3MR for rotating the reels 3L, 3C, 3R, the reel sensors 3SL, 3SC, 3SR for detecting the rotation of the reels 3L, 3C, 3R, and the medals paid out when a winning is generated are detected. The payout sensor 81 and the effect control board 102 are shown, and other switches, sensors, and the like are not shown. .

  The gaming electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, and 81, excluding the effect control board 102, transmit signals relating to the progress of the game. These are electronic components that input and output to and from the control board 101. The signals relating to the progress of the game include, for example, an operation for setting the bet amount for enabling the game to be started, an operation for starting the game, and an operation for deriving the display results of the reels 3L, 3C, and 3R. Signals output to the game control board 101 in response to a game operation, such as detection of inserted medals, detection of reel reference positions, detection of payout medals, etc., are output from the electronic components for gaming according to the progress of the game. A signal input to the game control board 101 and a drive signal for driving the reels 3L, 3C, 3R in response to the detection of the start operation, and a hopper 80 for paying out medals when a winning occurs. And a signal output from the game control board 101 in accordance with the progress of the game and input to the game electronic component.

  These gaming electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 signal to the game control board 101 in accordance with the progress of the game. And a second electronic component to which a signal from the game control board 101 is input in accordance with the progress of the game.

  Specifically, the single bet switch 45 and the MAXBET switch 46 operated when setting the bet amount and the inserted medal sensor 44 for detecting a medal inserted for setting the bet number are provided by the operation or the medal of the medal. It is a first electronic component that outputs a BET signal to the game control board 101 based on the detection. Since the game control unit 110 performs the bet amount setting process based on the reception of the BET signal, the bet amount cannot be set without these electronic components. That is, the game cannot be started unless the bet amount is set, so that the single BET switch 45, the MAX BET switch 46, and the inserted medal sensor 44 are gaming electronic components necessary for the progress of the game.

  The start switch 41 that detects an operation for starting a game is a first electronic component that outputs a start signal to the game control board 101 based on the detection of the operation. Since the game control unit 110 performs a process of starting a game (reel rotation process or the like) based on the reception of the start signal, the game cannot be started without this electronic component. That is, the start switch 41 is a game electronic component necessary for the progress of the game.

  The stop switches 42L, 42C, 42R that detect an operation for deriving the display result of the reels 3L, 3C, 3R are first electronic components that output a stop signal to the game control board 101 based on the detection of the operation. is there. The game control unit 110 stops the rotation of the corresponding reel 3L, 3C, 3R based on the reception of the stop signal and performs a process of deriving a display result. Therefore, without this electronic component, the reels 3L, 3C, 3R. Display result cannot be derived. That is, the stop switches 42L, 42C, 42R are gaming electronic components necessary for the progress of the game.

The reel sensors 3SL, 3SC, and 3SR that detect the rotation of the reels 3L, 3C, and 3R are first electronic components that output a detection signal of the reference position of the reel to the game control board 101. The game control unit 110 does not have this electronic component to perform processing such as stopping the rotation by grasping the position of the symbol of the corresponding reel 3L, 3C, 3R based on the reception of the detection signal of the reference position of the reel. It is impossible to derive the display results of the reels 3L, 3C, 3R, determine the winning, and the like.
That is, the reel sensors 3SL, 3SC, and 3SR are gaming electronic components necessary for the progress of the game.

  The payout sensor 81 that detects medals paid out when a prize is generated is a first electronic component that outputs a medal payout signal to the game control board 101 based on the detection of the medals. The game control unit 110 performs a payout process of paying out a number of medals according to the generated prize based on the reception of the payout medal detection signal. Can not pay out. That is, the payout sensor 81 is a game electronic component necessary for the progress of the game.

  The reel motors 3ML, 3MC, and 3MR that rotate the reels 3L, 3C, and 3R are second electronic components to which drive signals output from the game control board 101 are input. The reel motors 3ML, 3MC, and 3MR rotate the reels 3L, 3C, and 3R based on the input of the driving signal output from the game control board 101, and start changing the symbol display. Even if the reels 3L, 3C, and 3R are not actually rotated based on the above, the game control unit 110 outputs the reel drive signal and then receives the signals from the reel sensors 3SL, 3SC, and 3SR. , The game can be controlled to proceed assuming that the reels have been rotated. However, the timing at which the signals from the reel sensors 3SL, 3SC, and 3SR are input to the game control board 101 becomes an error unless the reel drive signal is output. To measure the output timing of the signal based on the rotation detection, a reel drive signal is required. That is, the reel motors 3ML, 3MC, and 3MR are gaming electronic components necessary for the progress of the game.

  The hopper motor 82 that drives a hopper tank that pays out medals is a second electronic component to which a drive signal output from the game control board 101 in response to occurrence of a prize is input. The hopper motor 82 drives the hopper 80 based on the input of the drive signal output from the game control board 101 to pay out medals, but does not actually drive the hopper 80 based on the signal input. Even if the game control unit 110 outputs a drive signal for the hopper 80 and then receives a signal from the payout sensor 81, the game control unit 110 can perform control to proceed with the game assuming that medals have been paid out. it can. However, the timing at which a signal is input from the payout sensor 81 to the game control board 101 is an error unless the drive signal of the hopper 80 is output. In order to measure the output timing of the signal based on the hopper tank, a drive signal for the hopper tank is required. That is, the hopper motor 82 is a game electronic component necessary for the progress of the game.

  In addition, these gaming electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 basically continue in common for a plurality of models. Since it is an electronic component to be used and there is little opportunity to remove it from the main body and replace it unless a failure or the like occurs, it is fixed to a predetermined portion of the main body of the slot machine. On the other hand, the game control board 101, the effect control board 102, and the like need to be replaced when the model is changed, and are removed from the main body at that time.

  First, the first electronic component will be specifically described. A driving tool is inserted into any one of a single BET switch 45, a MAXBET switch 46, or a connector of a cable provided between the inserted medal sensor 44 and the game control board 101. If the bet signal is incorrectly output from the driving tool to the game control board 101, the bet number may be set even though the bet number setting operation is not performed. When the connector of the driving tool is connected to one of the connectors of the cable provided between the start switch 41 and the game control board 101 and the start signal is incorrectly output from the driving tool to the game control board 101. The game may be started without performing the game start operation. The connector of the driving tool is connected to one of the connectors of the cables provided between the stop switches 42L, 42C, 42R and the game control board 101, and the stop signal is incorrectly transmitted from the driving tool to the game control board 101. When output, there is a risk that the rotation of the reels will be stopped without performing a stop operation.

  The connector of the driving tool is connected to one of the connectors of the cable provided between the reel sensors 3SL, 3SC, 3SR and the game control board 101, and the reel rotation signal is incorrect from the driving tool to the game control board 101. , There is a possibility that derivation of the display result of each of the reels 3L, 3C, and 3R, determination of winning, and the like may be performed without rotating the reels. The connector of the driving tool is connected to one of the connectors of the cable provided between the payout sensor 81 and the game control board 101, and the medal payout signal is incorrectly output from the driving tool to the game control board 101. Then, there is a possibility that the medals are counted without paying out the medals.

  Specifically, the second electronic component will be described. The connection of any one of the connectors of the cables provided between the reel motors 3ML, 3MC, 3MR and the game control board 101 is released, and the game control board 101 is released. When the drive signal output from the game device can be obtained by the driving device, the timing at which the reel drive signal is output from the game control board 101 can be specified by the driving device, so that the game control is originally performed from the reel sensors 3SL, 3SC, and 3SR. The reel rotation detection signal input to the substrate 101 may be output from the driving tool at an appropriate timing after the reel is rotated.

  In addition, the drive signal output from the game control board 101 when the connection of any one of the connectors of the cable provided between the hopper motor 82 and the game control board 101 is released can be obtained by a driving tool or the like. Then, since the timing at which the driving signal of the hopper tank is output from the game control board 101 can be specified on the driving tool side, the payout medal detection signal originally input from the payout sensor 81 to the game control board 101 is transmitted from the driving tool to the hopper tank. May be output at an appropriate timing after the drive.

  In this manner, the first electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, and 81 are output according to the progress of the game, and are normally input to the game control board 101. When a signal to be played is output from the driving tool, the game control unit 110 can perform control to advance the game based on the reception of the signal. On the other hand, when a signal that is output from the game control board 101 according to the progress of the game and originally input to the second electronic components 3ML, 3MC, 3MR, and 82 is input to the driving tool, The game control unit 110 can specify the output timing and the like of a signal output after the reel motors 3ML, 3MC, 3ML and the hopper motor 82 are driven, and based on this, when a new signal is input to the main control board 101, Since the game control unit 110 can control the progress of the game based on the reception of the signal, there is a possibility that an injustice such as automatically proceeding the game may be performed. In the slot machine 1 according to this embodiment, various measures are taken to prevent fraudulent acts due to the connection of a driving tool as described later.

  Next, a configuration around the power supply to the game control unit 110 in the game control board 101 will be described. FIG. 5 is a circuit diagram showing a supply line of a backup power supply to the game control unit 110.

  The DC voltage of +5 V generated by the voltage generation circuit of the power supply board 100 is supplied to the game control board 101. The DC voltage of +5 V supplied from the power supply board 100 is supplied to the VDD input terminal as a drive power supply of the game control unit 110, and is branched on the game control board 101 as shown in FIG. 5 to +5 V (VBB). Is formed. The + 5V (VBB) DC voltage supply line is connected to the memory backup power supply input terminal VBB of the game control unit 110 via the backflow preventing diode 312, and is set to the ground level on the power supply board 100 side. Are connected, and a large-capacity capacitor (not shown) is provided therebetween. As a result, a DC voltage of +5 V (VBB) can be stored in the capacitor, and when the power supply to the slot machine 1 is cut off, the voltage stored in the capacitor retains the storage state of the RAM 112 in the game control unit 110. It can be supplied as a backup power supply.

  In addition, the supply line of the DC voltage of +5 V (VBB) is not directly connected to the memory backup power supply input terminal VBB of the game control unit 110 on the game control board 101, but as shown in FIG. Via the cable 600a for connecting and connecting the board 101 and the operation unit relay board 107, the operation unit relay board 107, and the cable 601g for connecting and connecting the operation unit relay board 107 and the inserted medal sensor 44, and further folded back by the inserted medal sensor 44. , The cable 601g, the operation unit relay board 107, and the cable 600a, and is again connected to the game control board 101, and is connected to the memory backup power supply input terminal VBB of the game control unit 110. That is, when the power supply to the slot machine 1 is cut off, the voltage stored in the capacitor is transferred from the game control board 101 to the cable 600a, the operation unit relay board 107, the cable 601g, the inserted medal sensor 44, the cable 601g, and the operation unit. After passing through the relay board 107-cable 600a, it is supplied to the game control unit 110, and the storage state of the RAM 112 in the game control unit 110 is maintained.

  Therefore, in a state where the power supply to the slot machine 1 is cut off, the connection between the board-side connector 620a of the game control board 101 and the cable-side connector 610a of the cable 600a, the connection of the cable-side connector 611a of the cable 600a and the operation unit relay board The connection line of the backup power supply is disconnected by disconnecting any one of the connection between the board-side connector 621a of the operating unit 107 and the connection between the board-side connector 622g of the operation unit relay board 107 and the cable-side connector 612g of the cable 601g. As a result, the data in the RAM 112 of the game control unit 110 cannot be held and is lost. That is, when the connection between the connectors between the game control board 101 and the inserted medal sensor 44 is released at any one point, the backup data stored in the RAM 112 of the game control unit 110 is lost.

In the slot machine 1 according to this embodiment, the connection of the driving tool is made difficult by restricting the release of the connector connection between the game control board 101 and the game electronic component.
Specifically, connector connection between the game control board 101 and the inserted medal sensor 44, that is, connection between the board side connector 620a of the game control board 101 and the cable side connector 610a of the cable 600a, and the cable side connector 611a of the cable 600a The connection between the connector and the board-side connector 621a of the operation unit relay board 107 and the connection between the board-side connector 622g of the operation unit relay board 107 and the cable-side connector 612g of the cable 601g are restricted from being released. The release of the connection between the board side connector 620a and the cable side connector 610a is regulated by the connector regulating member 500, and the connection between the cable side connector 611a and the board side connector 621a, and the connection between the board side connector 622g and the cable side connector 612g. The release of the connection is regulated by the connector regulating member 650.

  Next, the configuration of the external output board 105, the medal IN signal and the medal OUT signal output from the external output board 105, and the security signal will be described in detail. The external output board 105 does not output a medal IN signal each time a medal is inserted from the medal insertion slot 13 or each time the one-sheet BET button 14 or the MAXBET button 15 is operated. The medal IN signal is output collectively. On the other hand, the medal OUT signal is output every time one medal is paid out from the hopper 80.

  FIG. 6 is a diagram showing an output format of a security signal output from the external output board 105. As described above, the security signal is to output a plurality of types of signals from the same external output terminal. As shown in the figure, the security signal is time-divided every Xms (X is an arbitrary number), and is divided into one frame period. Is output as 14Xms.

  The first Xms period of one frame period is a period for outputting a start bit, the last 6Xms period is a blank period, and the Xms period immediately before the blank period is a period for outputting a stop bit. During the period of 6Xms, six signals of a door open signal, a set value change signal, a closing error signal, a payout error signal, another error signal, and a signal during settlement are output in a time-divisional manner for each Xms period. It has become something.

The door open signal is a signal indicating that the front door is open when in the ON state, and the setting key switch 92, the setting switch 91, or the cables connecting the various boards 101 to 106 and the boards are slot machine. Since the front door 1 is installed inside the open front door, it is output when the front door is open because there is a possibility that an illegal operation has been performed. The set value change signal is a signal indicating that the set value is being changed when in the ON state. The change in the set value directly affects the payout rate of medals, so that the illegal operation is performed. Is output because there is a possibility that

The insertion error signal is a signal indicating that an error has occurred in the insertion of medals in the ON state and has not yet been recovered, and when an insertion error has occurred, an illegal medal insertion action (actually Is output because there is a possibility that an illegal instrument is used to fill credits without inserting a medal.
The payout error signal is a signal indicating that an error has occurred in the payout of medals when in the ON state and has not yet been recovered, and when a payout error has occurred, illegal actions such as pulling out medals to the hopper 80 have been made. This is output because it may have been performed.

  The other error signal is a signal indicating that an error other than the insertion error and the payout error has occurred in the ON state and has not yet been recovered. Errors other than the insertion error and the payout error do not directly occur in an attempt to increase the number of medals, but when an error occurs, there is a possibility that some kind of improper operation has been performed. It outputs another error signal. The settlement-in-progress signal is a signal that indicates that the medals are being settled when in the ON state. Although the medals are settled normally even if the medals are not illegal, if the medals are frequently performed, the settlement is incorrect. This is output because there is a possibility that an unusual act is being performed.

  The start bit is always on, and the stop bit and blank period are always off. There are six types of signals that indicate substantial contents as security signals: a door open signal, a set value change signal, a closing error signal, a payout error signal, another error signal, and a signal during settlement. Even after that, only 6 Xms continues during the OFF state, so it may be determined that the Xms period during which the security signal is ON after the OFF state has been reached for 7 Xms or more is the start bit period. it can.

  The security signal output from the external output board 105 is a signal that serially outputs a door open signal, a set value change signal, a closing error signal, a payout error signal, another error signal, and a signal during settlement. A predetermined output terminal board is provided between the external output board 105 and an external device such as a hall management computer, and a serial door open signal, a set value change signal, a closing error signal, a payout error signal, other error signals, Alternatively, the signal during settlement may be converted into parallel and output to an external device.

The engaging portions 523 and 523 are provided with locking holes when the locking claws 523a and 523a are mounted on the mounting side member 510 with the connector cover 520 connected to the board side connector 620a and the cable side connector 610a. The locking grooves 514 and 514 formed on the 513a are provided at positions to be engaged with the shallow groove portions 514a and 514a.

  Next, the state of attachment of the connector regulating member 500 to the board case 200 and the state of attachment of the board case 200 to the housing will be described.

  First, the game control board 101 is accommodated in the lower case 201 and the upper case 203 constituting the board case 200 and is sealed. In order for the lower case 201 and the upper case 203 to be in a sealed state, the corresponding engagement portions 230 of the upper case 203 are engaged with the two pairs of locking portions 210 of the lower case 201, respectively. One of the sealing pieces 211 of the case 201 and the corresponding sealing piece 231 of the upper case 203 are fixed with one-way screws.

  As is well known, a one-way screw has a function in which a screw can be screwed by rotation in one direction, but cannot be rotated in an attempt to rotate in the other direction, that is, the screw cannot be loosened. It is a screw. Therefore, when one of the sealing pieces 211 of the lower case 201 and the corresponding sealing piece 231 of the upper case 203 are fixed with one-way screws, one of the sealing pieces 211 and 231 is broken. If not, it is not possible to release these adhesions.

  By fixing the sealing piece 211 and the sealing piece 231, the longitudinal movement of the upper case 203 with respect to the lower case 201 is restricted, and as a result, the engagement of the upper case 203 with the locking portion 210 of the lower case 201 is restricted. The disengagement of the joint 230 is also restricted, and the upper case 201 and the lower case 203 are integrated with the game control board 101 housed therein, and the sealing pieces 211 and 231 are broken. Otherwise, it cannot be released.

  Next, the attachment-side member 510 is attached to the board case 200 in which the game control board 101 is sealed. The attachment-side member 510 elastically deforms both side pieces 510d, 510d outward, and is mounted on the step portion 203b of the upper case 203. Then, by releasing the elastic deformation, the locking pieces 511 and 511 are attached by engaging the engagement grooves 212 and 212 on the back surface of the lower case 201. At this time, the base piece 510a, the upper piece 510c, and 510c of the attachment-side member 510 abut on the upper surface of the step portion 203b of the upper case 203 and the bottom surface of the concave portion 203f, respectively, and the notch 512 provided on the base piece 510a has The board-side connector 620a of the game control board 101 accommodated in the board case 200 is aligned with the insertion hole 234 provided in the concave portion 203f of the upper case 203, and the cut-out 512 and the insertion hole 234. From outside.

  Next, the mounting screw 259 is screwed into the wall of the housing via the screw hole 252 of the mounting base 250 to fix the mounting base 250 to the housing, and the locking portions 257 and 257 of the fixing member 255 are fixed. The fitting members 255 are fitted into the engagement grooves 254a and 254a of the mounting base 250, and the fixing member 255 is mounted on the mounting base 250.

  Next, the board case 200 to which the attachment-side member 510 is attached is attached to the attachment base 250. Specifically, after the locking pieces 235 and 235 protruding from one end of the board case 200 are inserted into the locking holes 251a and 251a of the locking holes 251 and 251 of the mounting base 250, respectively, as shown in FIG. The board case 200 is accommodated between the side walls 250b and 250c of the mounting base 250, and the upper surface of the step 203a on the other end side of the board case 200 is locked by the locking claws 253a of the locking pillars 253. Temporarily fix to the mounting base 250. In this state, the four sealing pieces 232 provided at one end of the upper case 203 and the fixing holes 256 of the fixing member 255 mounted on the mounting base 250 are at the corresponding positions. The sealing piece 232 and the fixing member 255 are fixed to each other by screwing the one-way screw into the corresponding fixing hole 256 from above the 232.

  By fixing the sealing piece 232 and the sealing piece fixing member 255, the movement of the end of the substrate case 200 on the sealing piece 232 side in the detaching direction from the mounting base 250 is restricted, and the locking is performed. Since the horizontal movement of the board case 200 toward the sealing piece 232 is also restricted by the pillar 253, the locking pieces 235 and 235 protruding from one end of the board case 200 are removed from the locking holes 251a and 251a of the mounting base 250. It becomes impossible. Further, in this state, all the screw holes 252 of the bottom plate 250a of the mounting base 250 are covered with the board case 200, so that access to the mounting screws 259 is also impossible, and it is impossible to remove the mounting base 250 from the housing. Become. In this way, the board case 200 to which the mounting side member 510 is attached is fixed to the housing via the mounting base 250, and if the sealing piece 232 or the fixing member 255 is not broken, the board case 200 is attached to the housing. From which it cannot be removed.

  When the board case 200 to which the attachment-side member 510 is attached is fixed to the attachment base 250 (housing) so as not to be detachable, the side piece 510d of the attachment-side member 510 as shown in FIG. , 510d abut against the inner surfaces of the side walls 250b, 250c of the mounting base 250 and are clamped to restrict outward deformation of both side pieces 510d, 510d of the mounting side member 510. It becomes impossible to remove from 200.

Next, as shown in FIG. 9, the cable 600a is connected to the board-side connector 620a of the game control board 101 exposed through the insertion hole 234 of the board case 200 and the notch 512 of the base piece 510a in the mounting-side member 510. After the cable-side connector 610a is connected and the board-side connector 620a and the cable-side connector 610a are connected, as shown in FIG. 12, the cover 521 of the connector cover 520 covers the upper side of the cable-side connector 610a. Then, the locking cylinder 522 of the connector cover 520 is fitted into the locking hole 513a of the locking hole 513 of the mounting side member 510. Accordingly, the engaging portions 523 and 523 of the locking cylinder 522 abut against the inner periphery of the locking hole 513a and are elastically deformed inward. At this time, assuming that the engaging portions 523 and 523 are positioned to cover the cable-side connector 610a with the covering portion 521, the shallow groove portions 514a and 514a of the engaging grooves 514 and 514 formed on the inner surface of the locking hole 513a naturally. The locking cylinder 522 is further fitted, and the locking claws 523a and 523a at the tips of the engaging portions 523 and 523 reach the shallow groove portions 514a and 514a of the engaging grooves 514 and 514. As shown in FIG. 11A, the inward elastic deformation of the engaging portions 523 and 523 is released, and the locking claws 523a and 523a are engaged with the shallow groove portions 514a and 514a, respectively. The upward movement is regulated, and the side surface 521a of the covering portion 521 abuts against the side surfaces of the board-side connector 620a and the cable-side connector 610a. By rotating against the part 513 is restricted, and ligated with the mounting member 510 and the connector cover 520, a state of integrated connector regulating member 500 is formed.
In this state, since the engaging portions 523 and 523 are covered by the locking holes 513, the engaging portions 523 and 523 cannot be elastically deformed inward from the outside, and the connector cover 520 or the mounting-side member is not allowed. Unless the 510 is broken, the connector cover 520 cannot be removed from the mounting member 510.

  When the connector cover 520 is irremovably attached to the attachment-side member 510, as shown in FIGS. 13A and 13B, a part of the upper surface of the cable-side connector 610a is covered with the covering portion 521, and the cable-side connector 610 is covered. The movement of the cable connector 610a in the pull-out direction from the board-side connector 620a is restricted, and the removal of the cable-side connector 610a from the board-side connector 620a is restricted.

  In this manner, after the board case 200 is fixed to the housing with the mounting member 510 attached to the board case 200, the cable connector 610a is connected to the board connector 620a. By attaching the cable-side connector 610a to the mounting-side member 510 so as to cover a part of the cable-side connector 620a from above, the cable-side connector 610a cannot be removed from the board-side connector 620a.

  Next, a situation when the connection between the cable side connector 610a and the board side connector 620a is released will be described.

  To release the connection between the cable-side connector 610a and the board-side connector 620a, the mounting-side member 510 or the cable cover 520 is broken to remove the connector cover 520 from the mounting-side member 510, or the sealing piece 232 of the board case 200. Alternatively, it is necessary to break the fixing member 255, remove the board case 200 from the mounting base 250, and remove the mounting-side member 510 from the board case 200 with the connector cover 520 still mounted.

  For example, when it is necessary to disconnect the cable side connector 610a from the board side connector 620a due to a failure of the cable 600a, etc., the former method is used. Just remove it.

  First, a method of removing the connector cover 520 from the mounting-side member 510 when it is necessary to remove the cable-side connector 610a from the board-side connector 620a when exchanging the cable 600a will be described. The connecting piece 522a connecting the covering portion 521 of the cover 520 and the locking cylinder 522 is broken. As a result, the covering portion 521 is separated, and the locking cylinder 522 can be rotated with respect to the locking hole 513. In this state, by rotating the locking cylinder 522 counterclockwise in a top view, the engaging portions 523 and 523 move from the shallow groove portions 514a and 514a of the engaging grooves 514 and 514 to the positions of the deep groove portions 514b and 514b. Then, as shown in FIG. 11A, the locking claws 523a and 523a are engaged with the shallow groove portions 514a and 514a, and as shown in FIG. The engagement of the shallow groove portions 514a and 514a is released. This allows the locking cylinder 522 to move upward. As shown in FIG. 11C, when the locking cylinder 522 is pulled upward, the locking claws 523a and 523a are engaged with the deep grooves 514b and 514b. However, in this state, the engaging portions 523 and 523 are exposed, so that the engaging portions 523 and 523 can be elastically deformed inward. , 523a and the deep groove portions 514b, 514b are disengaged, and the locking cylinder 522 can be removed from the mounting side member 510, whereby the connector cover 520 is completely separated from the mounting side member 510, and the connector cover 520 is removed. The restriction on the movement of the cable-side connector 610a in the pull-out direction due to is also released, so that the connection between the cable-side connector 610a and the board-side connector 620a is released. Door will be able to.

  When the connector cover 520 is detached from the attachment-side member 510, the covering portion 521 and the locking cylinder 522 are broken, and once broken, they do not return to the original state. Therefore, the connection between the cable-side connector 610a and the board-side connector 620a. Will be left.

  Next, a method of removing the mounting-side member 510 together with the connector cover 520 from the board case 200 when it is necessary to remove the cable-side connector 610a from the board-side connector 620a when replacing the entire board case 200 will be described first. The sealing piece 232 of the substrate case 200 fixed to the fixing member 255 with a tool such as a nipper is broken. This allows the end of the board case 200 on the side of the sealing piece 232 to move in the direction in which the board base 200 is removed from the mounting base 250, so that the locking claw 253a of the locking column 253 and the step 203e of the board case 200 Is disengaged. Accordingly, the horizontal movement to the sealing piece 232 side is also possible, so the locking pieces 235 and 235 of the board case 200 are removed from the locking holes 251 a and 251 a of the mounting base 250. As a result, the board case 200 is removed from the mounting base 250, and the side pieces 510d, 510d of the mounting side member 510 can be deformed outward, without removing the connector cover 520 from the mounting side member 510. The attachment-side member 510 can be detached from the board case 200, and thus the attachment-side member 510 can be detached from the board case 200 in a state where the cable-side connector 610a is integrated with the connector cover 520. Since the restriction on the movement in the direction is also released, the connection between the cable side connector 610a and the board side connector 620a can be released.

  In order to remove the attachment-side member 510 from the board case 200 also by this method, it is necessary to break the sealing piece 232 of the board case 200 fixed to the fixing member 255. Therefore, a trace of disconnection between the cable-side connector 610a and the board-side connector 620a remains.

  Further, according to this method, although the sealing piece 232 of the board case 200 is broken and remains on the fixing member 255, the mounting-side member 510 can be removed from the board case 200 without removing the connector cover 520 from the mounting-side member 510. Therefore, by attaching the mounting-side member 510 in a state where the connector cover 520 is attached to the new board case 200 in which the game control board 101 is accommodated for replacement, the cable-side connector 610a and the board-side Disconnection with the connector 620a is disabled, a new fixing member 255 is mounted on the mounting base 250, and a new board case 200 with the mounting side member 510 with the connector cover 520 mounted thereon is mounted on the mounting base. 250 and fix the fixing member 255 and the sealing piece 232 to each other. Doing, it becomes again impossible removably mounting member 510, when releasing the connection between the cable-side connector 610a and the substrate-side connector 620a is in a state leave its mark. That is, in such a case, the mounting-side member 510 and the connector cover 520 can be reused.

  Next, a detailed structure of the connector restricting member 650 will be described.

  FIG. 14 is an exploded perspective view showing a mounting table 660 and a cover member 680 that constitute the connector restricting member 650. FIG. 15 is a perspective view showing a state where the cover member 680 is assembled to the mounting table 660. 16A is a cross-sectional view taken along the line EE of FIG. 15, and FIG. 16B is a cross-sectional view taken along the line FF of FIG.

  As shown in FIGS. 14 and 15, the connector restricting member 650 includes a mounting table 660 for mounting the operation unit relay board 107 and a cover member 680 for covering the mounting table 660 from above. After the operation unit relay board 107 is housed, the cable-side connectors 611a and 612g of the corresponding cables 600a and 601g are connected to the board-side connectors 621a and 622g of the operation unit relay board 107, respectively, and then the cover member 680 is attached to the case. By attaching to the body 610, removal of the cable-side connectors 611a and 612g from the board-side connectors 621a and 622g is regulated.

  The mounting table 660 is made of a transparent synthetic resin, and is formed in a substantially rectangular shape having a diameter larger than that of the operation unit relay board 107. As shown in FIG. 14, board side connectors 621 a, 622 a, 622 b, 622 c, 622 d to 622 f, and 622 g are mounted on the operation unit relay board 107, and both long sides of the mounting table 660 and short sides On one side surface of the side, when the operation unit relay board 107 is placed, the insertion ports of the operation unit relay board 107 are opened in the horizontal direction with respect to the mounting surface, and the board side connectors 622a, 622b, 622c, 622d to 622f. , 622g are provided one by one via a connecting piece 661a so as to protrude outward, avoiding the part where the 622g is located. On the inner peripheral surface of the locking hole 661b, a pair of locking claws 661c, 661c facing the center are formed at positions facing each other across the center.

  The cover member 680 is made of a transparent synthetic resin, and is formed in substantially the same shape as the mounting table 660. On one long side of the cover member 680, a position corresponding to the board-side connector 621a of the operation unit relay board 107 is located at the front. On the other long side, the cover portion 681 swelling toward the front side is provided at a position corresponding to the board side connectors 622a and 622b of the working unit relay board 110 on the other long side. Cover portions 689 bulging toward the front are formed at positions corresponding to 622c, 622g, and 622d to 622f, respectively.

  On the upper surface 681a of the cover portion 681, a notch 681b, which is smaller than the length of the long side of the cable-side connector 611a of the cable 600a and escapes the cable 600a connected to the board-side connector 621a, is formed over the outer side surface, Thereby, the covering surfaces 681c and 681 are formed on both side ends of the upper surface 681a, respectively.

  The cover 688 has cutouts 682a for allowing the cables 612a and 612b connected to the board-side connectors 622a and 622b to escape, and the cover 689 has a cable 612c connected to the board-side connector 622c. 682b for releasing the cable 612g connected to the board side connector 622g, and the notch 682d for releasing the cables 612d to 612f connected to the board side connectors 622d to 622f. Have been. In particular, the notch 682c for releasing the cable 612g connected to the board-side connector 622g is formed to have a width smaller than the length of the long side of the cable 601g. Pieces 683 and 683 are provided, respectively.

  In addition, locking holes are provided on both side surfaces on the long side and one side surface on the short side of the cover member 680 so as to protrude outward at positions corresponding to the locking holes 661 of the mounting table 660. An engaging cylinder 684 having substantially the same diameter as the inner peripheral surface of the inner peripheral surface 661b is provided via a connecting piece 684a. A locking hole 684 is formed on the outer peripheral surface of the locking cylinder 684 at a position corresponding to a pair of locking claws 661c provided on the inner periphery of the locking hole 661b, and the locking claw 661c is engaged. Can be combined.

  Next, the mounting state of the mounting table 660 and the cover member 680 will be described. First, as shown in FIG. 14, the operation unit relay board 107 is mounted on the mounting table 660, and the board-side connectors 621a, 622a, 622b, 622c. , 622d to 622f, and 622g corresponding to the cable side connectors 611a, 612a, 612b, 612c, 612d to 612f, and 612g, respectively. After connecting these cable side connectors to the board side connector, the cover member 680 is attached to the mounting table 660.

  Specifically, the locking cylinder 634 of the cover member 680 is fitted into the locking hole 661b of the corresponding locking hole 661 of the mounting table 660. By pushing the locking cylinder 634 into the locking hole 661b, the locking claw 661c in the locking hole 661b is engaged with the locking hole 684 of the locking cylinder 684. This makes it impossible to release the engagement between the locking claw 661c and the locking hole 684 from the outside. As shown in FIG. 15, the mounting table 660 and the cover member 680 are connected to each other by the locking hole. If the part 661 or the locking cylinder 634 is not broken, it will be in a non-removable assembled state.

  When the mounting table 660 and the cover member 680 are assembled, as shown in FIG. 16A, the upper surfaces of both ends of the cable-side connector 611a connected to the board-side connector 621a of the operation unit relay board 107 are covered with cover members. 680 are covered with the covering portions 681c, 681c, the movement of the cable-side connector 611a in the pulling-out direction from the board-side connector 621a is regulated, and the removal of the cable-side connector 611a from the board-side connector 621a is regulated. ing.

  When the mounting table 660 and the cover member 680 are assembled, as shown in FIG. 16B, the upper surfaces of both ends of the cable-side connector 612g connected to the board-side connector 622g of the operation unit relay board 107 are covered. 680, the movement of the cable-side connector 621g in the pull-out direction from the board-side connector 622g is regulated, and the removal of the cable-side connector 621g from the board-side connector 622g is regulated. ing.

  Next, a situation when the connection between the cable side connector 611a and the board side connector 621a and the connection between the cable side connector 621g and the board side connector 622g are released will be described.

  To release the connection between the cable-side connector 611a and the board-side connector 621a and the connection between the cable-side connector 621g and the board-side connector 622g, use a tool such as a nipper to connect the connection piece 684a that connects the locking cylinder 684 of the cover member 680. Break. Thereby, the main body of the cover member 680 and the locking cylinder 684 are separated from each other, and the cover member 680 can be removed from the mounting table 660. By removing the cover member 680 from the mounting table 660, the covering portions 681c and 681c can be removed. The restriction on the movement of the cable-side connector 611a in the pulling-out direction by the cable is released, and the restriction on the movement of the cable-side connector 621g in the pulling-out direction by the covering pieces 683, 683 is also released. And the connection between the cable-side connector 621g and the board-side connector 622g can be released.

  When the cover member 680 is detached from the mounting table 660, the main body of the cover member 680 and the locking cylinder 684 are broken, and once broken, it does not return to the original state. Remains in the locking hole 661b of the locking hole 661, a trace of the connection between the cable side connector 611a and the board side connector 621a and the connection between the cable side connector 621g and the board side connector 622g are released. It will be.

  In the slot machine 1, when the winning symbols are aligned on any of the winning lines of the variable display device 2, a winning is achieved. The types of winning combinations are determined according to the gaming state. In addition to the normal game state, the game state includes a challenge bonus and a single bonus as a special game state, and an RT in which the replay winning probability is higher than in the normal game state.

  The types of winning combinations are roughly divided into special roles (challenge bonus (1), challenge bonus (2), single bonus) accompanied by transition to a special game state, and small roles accompanied by a medal payout. (Watermelon, bell, cherry) and a replay (replay) that enables the next game to be started without setting the number of bets. FIG. 17A is a diagram illustrating combinations of types of winning combinations in the slot machine 1 and symbols in the variable display device 2.

  The challenge bonus (1) is a prize when a combination of “white 7-white 7-white 7” is arranged on any one of the winning lines in a game state other than the challenge bonus. The challenge bonus (2) is a prize when a combination of "white 7-red 7-red 7" is arranged on any one of the winning lines in a game state other than the challenge bonus. When the player wins the challenge bonus (1) or the challenge bonus (2), the game state shifts to the challenge bonus (if the RT game remains, the game is controlled to the challenge bonus along with the RT).

  When the gaming state is the challenge bonus, the maximum stop delay time for the left reel 3L is reduced from the normal 190 milliseconds to 75 milliseconds, and only one frame is allowed to be drawn in. However, regardless of the result of the internal lottery, Instead, it is possible to win small wins of watermelon, bell and cherry (ie, the winning flags of these small wins are set without depending on the internal lottery). That is, the small winning combination can be made according to the operation procedure of the stop buttons 12L, 12C, and 12R regardless of the result of the internal lottery. However, a single bonus and a replay, which will be described later, can be won even in the gaming state of the challenge bonus, provided that the winning flag is set by the internal lottery.

  Even if the player has won the challenge bonus (1) or the challenge bonus (2) in the internal lottery described later, “white 7” on the left reel 3L, “red 7” and “white 7” on the middle and right reels 3C and 3R. Are not arranged at intervals of five frames or less, and depending on the operation procedure of the stop buttons 12L, 12C, and 12R, there may be cases where these combinations are not won.

  The single bonus is won when the combination of “BAR-BAR-BAR” is completed on any one of the winning lines in any game state. When a single bonus is won, the game state shifts to the single bonus for the next one game only. If a single bonus is won in the single bonus gaming state, the gaming state of the next game is also a single bonus. The game state of the single bonus is a normal game state or a game state controlled separately from RT. If a single bonus prize is won in the gaming state of the challenge bonus, the challenge bonus is terminated only in the game with the single bonus winning as a premise of winning, so the single bonus gaming state is controlled together with the challenge bonus. Not at all.

  When a single bonus is won in the game state of the challenge bonus, the reels 3L, 3C, and 3R are stopped and controlled with priority on the single bonus prize. If it is not possible to win, if any of the small roles described below can be won, priority is given to watermelon, bell and cherry in this order.

  A watermelon wins when a combination of “watermelon-watermelon-watermelon” is completed on any one of the winning lines in any game state, and 15 medals are paid out. Since the maximum arrangement interval of “watermelon” for the left reel 3L is 7 frames, if the left stop button 12L is operated first in a game state other than the challenge bonus, even if the watermelon is won, no win is made. There is.

  However, in a game state other than the challenge bonus, as long as the left stop button 12L is operated first, the “watermelon” can be stopped in any of the upper, middle, and lower tiers, and the “watermelon” is displayed on the middle and right reels 3C, 3R. The “watermelon” is arranged at an interval of 5 frames or less and can be stopped at any position, so it has also won the challenge bonus (1) or the challenge bonus (2), and their derivation has priority over watermelon Except in the case where a watermelon has been won, it is possible to win a prize.

  A bell is won when the combination of "bell-bell-bell" is completed on any one of the winning lines in any game state, and eight medals are paid out. "Bells" are arranged at intervals of 5 frames or less on the middle and right reels 3C and 3R, but are arranged at intervals of 7 frames on the left reel 3L. If the stop button 12L is not operated first, the prize may not be won even if the bell is won.

  However, in a game state other than the challenge bonus, as long as the left stop button 12L is operated first, the "bell" can be stopped in any of the upper, middle, and lower tiers. "Bell" can be stopped at the position of "Bell", so it is also elected to the Challenge Bonus (1) or the Challenge Bonus (2) unless the derivation of these is prioritized over the Bell. If you do, you can always win.

  In any game state, the cherry wins when a symbol of "Cherry" is derived on any one of the winning lines for the left reel 3L, and two medals are paid out. For the left reel 3L, only one "cherry" is arranged. Therefore, even if the stop button 12L is not operated at a predetermined timing in a game state other than the challenge bonus or in the game state of the challenge bonus, the cherry is displayed. No prize will be won even if elected.

  In the game state of the challenge bonus, the winning combination of the watermelon, bell, and cherry is set regardless of the result of the internal lottery, so that the winning combination can be made in accordance with the operation procedure of the stop buttons 12L, 12C, and 12R. Yes, but the one with the largest number of medals paid out has priority. Further, when a single bonus or a replay is won in the gaming state of the challenge bonus, the derivation of these is given priority over the small combination of watermelon, bell, and cherry. The display mode to be derived by the stop control of the reels 3L, 3C, 3R in the game state of the challenge bonus will be described later in detail.

  A replay is won when the combination of “JAC-JAC-JAC” is completed on any one of the winning lines in any game state. When a replay is awarded, there is no payout of medals, but the next game can be started without setting the number of bets again. Therefore, three medals corresponding to the number of bets of 3 which have become unnecessary in the next game will be paid out. Is substantially the same.

  "JAC" is arranged at intervals of 5 frames or less for all of the reels 3L, 3C and 3R. In a gaming state other than the challenge bonus, within the range of the maximum stop delay time of the stop button 12L (the pull-in range of 4 frames), "Cherry" is kicked off for the left reel 3L and "JAC" is placed on one of the upper, middle and lower tiers. Can be stopped. If the left stop button 12L is operated first when a replay has been won, a replay can be won without a compound winning with the cherry. On the other hand, when the left stop button 12L is not operated first, "JAC" is stopped at the middle winning line for the reel 3C and / or the right reel 3R which are stopped first. Combined prize with Cherry will not occur.

  When the player has won the replay in the gaming state of the challenge bonus, the reels 3L, 3C, and 3R are stopped and controlled with priority given to the replay winning, but there is no problem if the cherry is simultaneously won at the same time. Even if the replay cannot be won even if the replay is prioritized or the stop control is performed (this may occur when the left stop button 12L is not operated first), the other small wins are won. If they can do that, they will be given priority in the order of watermelon, bell and cherry.

  Although not defined as a winning combination, any one of the winning lines is displayed as “Red 7-JAC” in a normal gaming state or RT (controlled by completing a challenge bonus by winning a single bonus). When the combination of “−JAC” is completed, the RT symbol is derived, and the gaming state is controlled to RT. This RT is continuously controlled until the 300 games are consumed. Note that the RT symbol is derived by missing the single bonus, and is a display mode that can be derived simultaneously with the winning of the cherry from the positional relationship between “red 7” and “cherry” on the left reel 3L.

  As will be described later, there is a case where the player wins a small role (watermelon, bell, cherry) or replay in a state where the winning of the challenge bonus (1) or the challenge bonus (2) is carried over. The replay is derived prior to the challenge bonus (1) or the challenge bonus (2), and the challenge bonus (1) or the challenge bonus (2) is derived prior to the small role.

  By the way, there are cases where the gaming state of the challenge bonus is controlled based on the winning of the challenge bonus (1) and cases where the gaming state is controlled based on the winning of the challenge bonus (2). However, the number of medals to be paid out as the termination condition is different. In other words, the control of the challenge bonus to the gaming state is performed in accordance with the CB counter (provided in the RAM 112), which is decremented by the number of medals paid out for the small win, but when the challenge bonus (1) is won. Is set to 30 as the initial value of the CB counter, and when winning the challenge bonus (2), 150 is set as the initial value of the CB counter.

  Since the gaming state of the challenge bonus continues until the value of the CB counter becomes 0, for example, a challenge bonus controlled based on the winning of the challenge bonus (1) will not be won as a single bonus. If it is assumed, if all of the watermelons win, the game will be completed in only two games. However, if all of the cherries win, 15 games can be continued. If the prize is a cherry prize, the number of continuous games of the challenge bonus will be 15 even if there is no loss).

  Further, in practice, a single bonus lottery is performed in the gaming state of the challenge bonus. When the single bonus is won, the value of the CB counter is cleared to 0 at the end of the game, and the gaming state of the challenge bonus is changed. It will be terminated. However, at the time of winning the single bonus, it is possible to derive an RT symbol by operating the stop buttons 12L, 12C, 12R as described later, and to control the gaming state to RT. However, when the gaming state is already at RT, RT is not controlled from 1 again.

The game state of the RT continues for 300 games after the RT symbol is derived, and is not ended by winning or winning of the challenge bonus (1) or the challenge bonus (2).
Even during the game in which the gaming state is controlled by the challenge bonus along with the RT based on the winning of the challenge bonus (1) or (2), the number of RT games is counted. Even games that are controlled to a single bonus in conjunction with RT are counted as RT games.

  Hereinafter, the internal lottery will be described. In the internal lottery, it is determined whether or not the winning of each of the above-mentioned roles 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 the internal lottery (an integer from 0 to 65535) is obtained from the random number generation circuit 115. Then, for each combination determined according to the gaming state, the acquired random number for the internal lottery, the number of bets set by the player, and the combination of 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 gaming state and each set value is sequentially added to the random number for the internal lottery, and when the result of the addition overflows, It is determined that the game has been won. If the winning is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is registered in the winning combination table for each gaming state in the ROM 113.

  FIG. 17B is a diagram showing a winning combination table for each gaming state. The winning combination table for each gaming state is stored in advance in the ROM 113, and is a table in which the number of determination values of the winning combinations to be selected for each gaming state in the internal lottery is registered. Here, only those having a predetermined set value are shown, but slightly different values are registered according to the difference between the set values. In the internal lottery, a plurality of winning combinations may be simultaneously targeted for the lottery. In accordance with the gaming state winning combination table, in the internal lottery, the determination values of the challenge bonus (1), the challenge bonus (2), the single bonus, the watermelon, the bell, the cherry, and the replay are sequentially obtained according to the gaming state. .

  However, in the gaming state of the challenge bonus, since 0 is registered as the determination value number of the challenge bonus (1) and the challenge bonus (2), these combinations are not won. Although 0 is registered as the judgment value for the small combination of watermelon, bell, and cherry, the winning flag of these combinations is set regardless of the result of the lottery in the gaming state of the challenge bonus, and the stop button is set. Wins can be made according to the operation procedure of 12L, 12C, 12R.

  In any game state, 1310 is registered as the single bonus determination value number, and the single bonus is won with a probability of approximately 1/50. If a single bonus is won in the game state of the challenge bonus, the game state of the challenge bonus is terminated after the end of the game. Since the game itself that has won the single bonus is still in the game state of the challenge bonus, the maximum stop delay time of the left reel 3L remains at 75 milliseconds, and the small watermelon, bell, and cherry are also won. Can be done. The fact that the single bonus has been won is not notified to the player at least in the gaming state of the challenge bonus.

  In the gaming state of the single bonus, a value larger by one than the number of bell determination values in the normal gaming state or RT is registered as the number of bell determination values. Since the single bonus is a normal gaming state or a gaming state controlled together with RT, the number of replay determination values indicates whether the gaming state controlled together is the normal gaming state or RT. Is obtained in the internal lottery. The same applies to the number of replay determination values in the challenge bonus.

  In a game state other than the challenge bonus, the challenge bonus (1) or the challenge bonus (2) is a target of the lottery, but the player wins the challenge bonus (1) or the challenge bonus (2) in the game before the previous game. When the winning flag is carried over, the challenge bonus (1) or the challenge bonus (2) is not won. If the winning flag of the challenge bonus (1) or the challenge bonus (2) is carried over and a single bonus, a watermelon, a bell, a cherry, or a replay is won, the winning flag of these roles is set to the challenge bonus ( 1) The winning flag or the challenge bonus (2) It is set to be superimposed on the winning flag.

  Further, the number of replay determination values in the normal gaming state and RT is the same regardless of the set value. However, the total number of determination values for replay is 8992 in a normal gaming state, but is 50604 in RT (the same applies when controlled in conjunction with a challenge bonus or a single bonus). The replay winning probability in the normal game state is approximately 1 / 7.3, whereas the replay winning probability in RT is approximately 1 / 1.4, and the replay winning probability is extremely high. It is what you do.

  By setting the total winning probability of the replay in this way, excluding the case where the control is performed in accordance with the challenge bonus, the payout rate of the medals is smaller than 1 in the normal gaming state (that is, the bet amount). (The smaller the number of medals to be paid out to the small wins in the internal lottery than the number of medals to be inserted for setting the number, the smaller the number of medals to be paid out). However, in RT, the total probability of replay winning becomes higher. As a result, the payout rate of the medals becomes larger than 1 (that is, the number of medals to be paid out to the small winning combination in the internal lottery with respect to the number of medals to be inserted for setting the bet amount) Is bigger).

  The medal payout rate in the single bonus depends on whether the normal gaming state or the RT is controlled in conjunction with the single bonus because the number of judgment values of the RT and the bell differs only by one. , Less than one or greater than one.

  The payout rate of medals in the challenge bonus is greater than 1 because a watermelon of 15-sheet role can be won in all games. However, if the stop operation is performed so that the cherry, which is the two-piece combination, wins, instead of the watermelon with the largest number of payout medals, the actual medal payout rate becomes smaller than one. Note that the relationship of the payout rate of medals according to the gaming state described above is the same even when the set value is any of 1 to 6.

  Next, stop control of the reels 3L, 3C, 3R will be described. The reels 3L, 3C, and 3R constituting the variable display device 2 are rotated on condition that the start lever 11 is operated and a predetermined time has elapsed from the start of rotation of the reels 3L, 3C, and 3R in the previous game. Be started. When the player operates the stop buttons 12L, 12C, 12R, the rotation of the corresponding reels 3L, 3C, 3R is stopped.

  The rotation of the reels 3L, 3C and 3R is stopped within a maximum stop delay time of 190 milliseconds (75 milliseconds for the left reel 3L during the challenge bonus) from the operation of the corresponding stop buttons 12L, 12C and 12R. The winning flag is set within the maximum stop delay time of 190 milliseconds (the left reel 3L during the challenge bonus is 75 milliseconds) so that the symbols with the flag set are aligned on the winning line. It is controlled so that the symbols of the winning combination are not aligned on the winning line.

  In a game state other than the challenge bonus, if the replay winning flag is set in duplicate by winning the replay with the challenge bonus (1) winning flag or the challenge bonus (2) winning flag carried over, the replay is performed. Is controlled so that the symbol of the symbol (1) is preferentially aligned on the winning line. Regardless of the operation procedure of the stop buttons 12L, 12C, and 12R, the player wins the replay. In this case, the player does not win the challenge bonus (1) or the challenge bonus (2).

  Here, the reason why the player does not always win the challenge bonus (1) or the challenge bonus (2) by winning the replay is that if the stop control for giving the priority to the replay is performed, the reels 3L, 3C, and 3R have the " This is because the arrangement of "JAC" does not cause a replay to be missed, and this does not mean that the stop control for giving priority to the replay and winning is a stop control for not missing the replay. Unlike the arrangement shown in FIG. 2, if the symbol interval of "JAC" is larger than 5 frames, the replay may be missed even in the stop control for giving priority to the replay and winning.

  If the challenge bonus (1) winning flag or the challenge bonus (2) and the watermelon winning flag or the bell winning flag are set to overlap, the symbol of the challenge bonus (1) or the challenge bonus (2) is prioritized. Is controlled to be aligned on the winning line. When the symbols of the challenge bonus (1) or the challenge bonus (2) cannot be aligned on any of the winning lines by the operation procedure of the stop buttons 12L, 12C, and 12R, "watermelon" or "bell" is won. If they are arranged on the line, "watermelon" or "bell" can be arranged on the winning line and a watermelon or a bell can be won.

  More specifically, the stop buttons 12L, 12C, and 12R are operated in the order of left, middle, and right when the winning flag and the watermelon winning flag are set to overlap each other. Then, if the operation timing of the left stop button 12L is the timing at which the 19th symbol is located at the lower stage of the left reel 3L, the first “watermelon” and the third “white 7” in the pull-in range of 4 frames. Are stopped in the lower and upper sections, respectively, so that both the challenge bonus (1) and the watermelon can leave a prize, so they are stopped at that position. If the number 8 symbol is located at the lower level, the number 8 “watermelon” can be stopped at the lower level to leave the possibility of watermelon winning, but the number 3 “white 7” is changed to 4 Since it cannot be stopped in the range where the frame is pulled in, it is stopped at that position.

  When the middle stop button 12C is operated in a state where “white 7” is stopped at the upper part of the left reel 3L and “watermelon” is stopped at the lower part, the operation timing is such that the symbol No. 20 is displayed at the lower part of the middle reel 3C. If it is the timing of the position, the third “white 7” and the zero “watermelon” of the reel 3C can be stopped at the lower stage within the pull-in range of four frames. In this case, since the winning of the challenge bonus (1) is prioritized, the third "white 7" is stopped at the upper stage, and the zero "watermelon" is not stopped at the lower stage. Finally, if the timing at which the right stop button 12R is operated is the timing at which the 20th to 3rd symbols on the reel 3R are located in the upper row, the 3rd "white 7" is stopped in the upper row and the challenge bonus (1 ), But at any other time, the third "white 7" cannot be stopped in the upper row, and therefore no winning is won.

  When "watermelon" is stopped at the lower stage of the left reel 3L and the middle stop button 12C is operated in a state where "white 7" is not stopped, it is arranged on the reel 3C within a pull-in range of 4 frames. Any of the “watermelons” can be stopped at the lower level, so “watermelon” is stopped at the lower level. If the operation timing of the middle stop button 12C is, for example, the timing at which the first symbol is located at the lower stage, the symbol “White 7” of the challenge bonus (1) can be stopped, but the challenge has already been performed. Since the possibility of winning the bonus (1) has disappeared, the fifth watermelon is drawn to the lower row and stopped without stopping it in any of the upper, middle and lower rows. The same applies to the stop control of the right reel 3R.

  If the challenge bonus (1) winning flag or the challenge bonus (2) and the cherry winning flag are set in an overlapping manner, the winning bonus line (1) or the challenge bonus (2) is given priority over the winning line. It is controlled to be aligned on the top. This is a case where the symbols of the challenge bonus (1) or the challenge bonus (2) cannot be aligned on any of the winning lines by the operation procedure of the stop buttons 12L, 12C, and 12R, and any one of the stages of the left reel 3L. If “Cherry” can be derived, the “Cherry” is derived and the cherry is won.

  The single bonus can be won in a game state other than the challenge bonus or in a game state of the challenge bonus. When a single bonus is won in a game state other than the challenge bonus, the maximum stop delay time of 190 milliseconds from the operation of the stop buttons 12L, 12C, and 12R for each of the reels 3L, 3C, and 3R (the pull-in range of four frames) If the symbols of the single bonus can be aligned on the winning line in the parentheses), the single bonus is won.

  When a single bonus is won in a game state other than the challenge bonus, the winning flag of the challenge bonus (1) or the challenge bonus (2) may be set in an overlapping manner. Due to the arrangement of the symbols on the reels 3L, 3C, 3R, they are not derived at the same time in the first place.

  Since the winning flag of the role other than the challenge bonus (1) and the challenge bonus (2) is not set to be the same as the winning flag of the single bonus, the single flag is set within the maximum stop delay time of 190 milliseconds. If no bonus can be won, no winning will be won. In addition, since "Red 7" located at the position sandwiching "Cherry" with respect to the left reel 3L is also kicked off, no RT symbol is derived in a game state other than the challenge bonus.

  Further, in the gaming state of the challenge bonus, the maximum stop delay time of the left reel 3L is reduced from the normal 190 ms to 75 ms (the number of drawn frames is limited from the normal 4 frames to 1 frame). However, according to the operation procedure of the stop buttons 12L, 12C, and 12R, the watermelon can be awarded in the priority order of the watermelon, the bell, and the cherry. If a single bonus or a replay has been won, however, stop control of the reels 3L, 3C, 3R is performed with priority given to winning.

  First, a case where neither the single bonus nor the replay is won will be described as an example. When the player operates the left stop button 12L first, the operation timing is set to the pull-in range of one frame on the left reel 3L. When the timing at which the "watermelon" can be stopped at any of the upper, middle, and lower tiers, that is, the timing at which the 19th to 15th symbols are located at the lower tier, the "watermelon" is stopped at any of the upper, middle, and lower tiers . As for the middle and right reels 3C and 3R, the "watermelon" is stopped within a pull-in range of 4 frames on the winning line where the "watermelon" is stopped for the left reel 3L ("watermelon" is spaced within 5 frames). (It can be stopped at any position because it is arranged), make the watermelon win.

  The operation timing of the left stop button 12L, which is operated first, cannot stop “watermelon” in any of the upper, middle, and lower tiers on the left reel 3L. If the timing is such that the symbol is located at the lower stage, the "bell" is stopped at the upper stage by pulling in one frame. As for the middle and right reels 3C and 3R, the "Bell" is stopped within the pull-in range of 4 frames on the winning line where the "Bell" is stopped for the left reel 3L ("Bell" is an interval of 5 frames or less). (Because they are arranged, they can be stopped at any position.)

  The operation timing of the left stop button 12L operated first cannot stop both “watermelon” and “bell” on the left reel 3L, but can stop it if “cherry”, that is, the 16th or If the 17th symbol is at the lower position, the 17th, 18th, and 19th symbols are stopped at the lower, middle, and upper positions, respectively, at the position where one frame is drawn or left as it is. Then, since the 18th "cherry" is stopped in the middle stage, the prize is won.

  If the left stop button 12L is to be operated thirdly, winning of a watermelon with a large number of paid-out medals is given priority, so that "watermelon" is one of the winning lines for the middle and right reels 3C and 3R. There is a tempai on the top (up to two of the winning combinations are aligned on the winning line). Depending on the operation timing of the stop buttons 12C and 12R, “Bell” may be tempered on the winning line on the winning line where “watermelon” is tempered.

  In this case, if the operation timing of the last operated left stop button 12L is a timing at which “watermelon” can be stopped on the winning line with “watermelon”, the watermelon is won. Although it is not possible to stop "watermelon" on the winning line where "watermelon" is tempered, but at the time when it is possible to stop "bell" on the winning line with "tempered bell" above it, Win a bell. “Bell” cannot be stopped at the winning line where “Bell” is tempered, but if the timing allows “Cherry” to be stopped at any of the upper, middle and lower stages, the cherry is won.

  Even when the left reel 12L is operated second, the “winning line with“ XX ”being tempered” is read as the “winning line with“ XX ”stopped,” and “winning is performed”. "Is replaced with" tempering. "In the final stop or right stop control of the reels 3C and 3R, if" watermelon "is tempering," # "is displayed on the winning line. The “watermelon” can be stopped, and the “bell” can be stopped at the winning line if the “bell” is tempered.

  When the single bonus winning flag is set in the game state of the challenge bonus (although the game state of the challenge bonus ends only in the game concerned), the symbol of the single bonus is displayed by operating the stop buttons 12L, 12C, and 12R. If it can be aligned with any one of the winning lines, the symbols of the single bonus are aligned on the winning line. If the symbols of the single bonus cannot be aligned, the operation of the stop buttons 12L, 12C, and 12R can be used to derive the cherry to the left reel 3L and align the symbols of "watermelon" and "bell" with the winning line. If it is possible or the RT symbols can be aligned, such reel control is performed.

  More specifically, for example, when the player operates the left stop button 12L first, the operation timing is such that the 13th “BAR” can be stopped at any of the upper, middle, and lower tiers on the left reel 3L. In other words, if the timing of the 10th to 13th symbols is at the lower position, "BAR" is stopped. Here, if the operation timing of the stop button 12L is the timing at which the 10th or 11th symbol is located in the lower row, the 13th “BAR” is stopped in the upper row, and the 11th “watermelon” is stopped in the lower row. On the other hand, if the 12th or 13th symbol is at the lower position, the 13th “BAR” is stopped at the lower position and the 15th “watermelon” is stopped at the upper position.

  For the middle and right reels 3C and 3R, if the stop buttons 12C and 12R are operated at the timing at which "BAR" can be stopped on the winning line where "BAR" has been stopped for the left reel 3L, "BAR" is displayed. Make a single bonus prize aligned on the prize line. It is no longer possible to align "BAR" on the winning line, but if there is a possibility that "watermelon" can be aligned on the winning line, the reel 3C will align the "watermelon" symbol on the winning line. 3R stop control.

  If the operation timing of the left stop button 12L operated first cannot stop the thirteenth “BAR” on the left reel 3L, the same as when the single bonus and the replay are not won as described above. Stop control is performed. That is, when the stop button 12L is operated at the timing when the 16th or 17th symbol is located in the lower row, the 17th, 18th, and 19th symbols are stopped in the lower row, the middle row, and the upper row, respectively, “Cherry” is stopped in the middle row to win the cherry, and “Red 7” is stopped in the upper and lower rows. When the stop button 12L is operated at the timing when the 18th symbol is located in the lower row, the 19th “red 7” is stopped in the lower row, and the 0th “bell” is stopped in the upper row. If the stop button 12L is operated at any other timing, the “watermelon” is stopped at any of the upper, middle, and lower stages.

  Thereafter, when the middle and right stop buttons 12C and 12R are operated, if the "watermelon" is stopped in any of the upper, middle and lower tiers of the left reel 3L, the middle and right reels 3C and 3R are stopped. Since the “watermelon” can be stopped at an arbitrary position regardless of the operation order and timing, the “watermelon” is stopped on the winning line where the “watermelon” is stopped for the left reel 3L, and the watermelon is stopped. Win a prize. In this case, no RT symbol is derived.

  In the state where "watermelon" is not stopped in any of the upper, middle and lower stages of the left reel 3L, but "bell" is stopped in the upper stage and "red 7" is stopped in the lower stage, the middle and right reels 3C, 3R Regardless of the order or timing of the stop operation, the derived "bell" can be stopped at an arbitrary position, so that the "bell" is displayed on the winning line where the "bell" is stopped for the left reel 3L. And stop the bell. Here, by winning the bell, even if “red 7” is also stopped on the left reel 3L, the RT symbol is not derived.

  In the state where “Cherry” is stopped in the middle of the left reel 3L and “Red 7” is stopped in the upper and lower rows, since the winning of the cherry has already been determined only by the left reel 3L, the middle and right For the reels 3C and 3R, there is no need to perform stop control for causing the cherry to win. In this case, the left and right reels 3C and 3R may be stopped at an arbitrary position on the winning line where the red reel 3L is stopped, regardless of the order or timing of the stop operation. Stop the "JAC" that can be done and derive the RT symbol.

  When the left stop button 12L is not operated first, if the corresponding stop operation is performed at a timing at which "BAR" can be derived to the middle or right reel 3C or 3R operated first, the corresponding reel is operated. "BAR" is stopped for the remaining reels. If a stop operation is performed at a timing at which "BAR" can be stopped on the winning line where "BAR" has been stopped for the first stopped reel, "BAR" will be displayed. Are aligned on the winning line and a single bonus is won.

  If the left stop button 12L is not operated first, and if the stop buttons 12L, 12C, and 12R are not operated at the timing when a single bonus is won, priority is given to watermelon, bell, and cherry in the order of watermelon, bell, and cherry. Stop control of the reels 3L, 3C, 3R is performed so as to make a winning. In this case, there may be a case where “watermelon” is stopped at the upper part of the middle reel 3C and / or right reel 3R, and “JAC” is stopped at the middle part of “watermelon”. After that, when the left stop button 12L is operated, the RT symbol can be derived in accordance with the operation timing in some cases. However, at least the 16th to 19th symbols need to be at the timing at which the lower symbol is located in the lower row. No.

  The above-described stop control of the reels 3L, 3C, and 3R is performed according to the setting status of the winning flag (and the symbols derived to the reels already stopped) and the gaming state (however, the setting status of the winning flag other than the challenge bonus). If it is the same, there is no difference according to the game state) .A stop control table that defines the relationship between the stop operation positions and the stop positions of the reels that have not stopped yet is created in advance for the unstopped reels, and the stop is performed. When the buttons 12L, 12C, and 12R are respectively operated, the rotation of the corresponding reel is stopped by referring to a stop control table created in advance. In the stop control table, the stop position is uniquely determined for the stop operation position.

  In the above-described gaming characteristics, in order for the player to gain profit after the gaming state is controlled by the challenge bonus, if the player has won the single bonus, the player dares to drop the single bonus without winning the single bonus. It is better to derive a symbol and control the gaming state to RT. In order to derive the RT symbol at the time of winning the single bonus, for example, if the left stop button 12L is operated first, the symbol No. 16 or 17 is operated at the timing when the symbol No. 16 or 17 is located in the lower row on the reel 3L. At this point, the player has no idea that the single bonus has been won.

If the left stop button 12L is operated first while the gaming state is controlled by the challenge bonus, at least two medals can be obtained by winning a cherry.
On the other hand, if the left stop button 12L is not operated first, depending on the operation timing of the stop buttons 12C and 12R, there may be no winning of any kind of small role, and the challenge bonus ends if the single bonus is won. Even if it does, the RT symbol is not derived. After winning the single bonus, there is almost no increase in profit.

  Hereinafter, a method of advancing a game in the challenge bonus will be described. Here, the procedure of operating the left stop button 12L first is a procedure conventionally performed by many players in a slot machine except for a special case. Also, the game in the challenge bonus will be described on the assumption that the left stop button 12L is operated first by the player.

  The game state of the challenge bonus ends when the number of paid-out medals reaches a specified number (30 or 150), regardless of whether the bonus bonus (1) or the challenge bonus (2) is won. I do. However, since three medals are consumed per game, only when the game is controlled by the challenge bonus, the player is awarded to the small role with the largest possible number of payouts, and the challenge bonus is reduced with a small number of games. Digesting gives the player more benefits.

  Assuming that only the watermelon with the largest number of medals to be paid out wins, for example, the gaming state of the challenge bonus controlled by winning the challenge bonus (1) ends in only two games. Even if a player wins in a watermelon → bell → (in no particular order) → watermelon pattern in which the profit obtained by the player is greatest, the game state of the challenge bonus ends in three games. In such an operation method, the player can obtain many profits in a short period of time, but the chance to win a single bonus that gives the RT a chance to control the game state is two to three games. There is only a game.

  On the other hand, assuming that only the bell with the smallest payout number of medals is won, for example, 15 games occur until the payout medal number in the challenge bonus controlled by winning the challenge bonus (1) reaches the specified number. Become. In other words, there are also 15 games to be won for the single bonus that gives the RT a chance to control the gaming state. (However, if the single bonus is won first, the gaming state of the challenge bonus will be changed at that time. Ends). Cherry prize will result in a loss of one medal per game, but even if a maximum of 15 medals will be lost in the entire challenge bonus, the probability of winning a single bonus by the end of the 15 games Given the benefits that would be gained over the entire 300 game RT, the losses are fully recoverable.

  Therefore, if you want to make a profit not only in the game state of the challenge bonus but also in the RT, the strategy of delaying the end of the challenge bonus and waiting for the winning of the single bonus that can derive the RT symbol is adopted. It becomes. In addition, even if the single bonus is won, the RT symbol is not derived unless the left stop button 12L is operated at the same timing as when the cherry is won, so that the end of the challenge bonus is postponed, and the game state is extended. In order to obtain a chance to control the game by the RT, the player may perform a stop operation so that the cherry can be won in each game in the game state of the challenge bonus.

  Here, the operating procedure for causing the cherry to win is to operate the stop button 12L first with the left stop button 12L and at the timing when the 16th or 17th symbol is positioned on the lower reel 3L. is there. The design of "Cherry" is sandwiched between "Red 7" at the top and bottom, and since these three designs are clustered in red, the player may operate the stop button 12L aiming at this portion. It will be.

  Further, if the left stop button 12L is operated first at the timing when the 16th or 17th symbol on the left reel 3L is located at the lower level, if the single bonus is won, the RT symbol is further derived. Will be able to The player is not notified of the winning of the single bonus, but if the stop button 12L is operated so that the cherry can be won without knowing that, the RT symbol is derived even if the single bonus is won, and the game is performed. The state is controlled by RT.

  On the game control board 101 side, the internal lottery is performed as described above, and the rotation of the reels 3L, 3C, 3R is stopped according to the result and the operation timing of the stop buttons 12L, 12C, 12R, and a prize is generated. It will be. The occurrence of a prize gives a medal payout or a transition of a game state as a payout. In this way, in accordance with the progress of the game on the game control board 101 side, a unique effect is performed on the effect control board 102 side. Be done. In order to perform such an effect, the CPU 121 of the effect control board 102 must be able to recognize the progress of the game on the game control board 101 side. Is transmitted from the game control board 101 to the effect control board 102.

  The CPU 121 of the effect control board 102 sequentially takes out the commands received from the game control board 101 one by one, and based on the command, the reel lamp 3LP, the liquid crystal display 4, the speakers 7L, 7R, 7U, the game effect lamps 75A to 75M. And the like to control the effect means and perform the effect processing independently. The commands transmitted from the game control board 101 to the effect control board 102 include a winning status notification command indicating a setting status of a winning flag in the RAM 112, a gaming state command indicating a gaming state applied in the next game, and the like. be able to.

  Hereinafter, a gaming operation in the slot machine 1 according to the embodiment will be described. Here, first, a special process that is executed when the slot machine 1 is activated will be described, and then, a process when each game is repeatedly executed in the slot machine 1 will be described. In the following description, in the case of "game", in a narrow sense, it means from operation of the start lever 11 to stop of the reels 3L, 3C, 3R. Of course, when playing the game, the betting number is set before the start lever 11 is operated, and the medals are paid out and the game state is shifted after the reels 3L, 3C, and 3R are stopped. Are also included in the “game” in a broad sense. In the following description, a description of a process not related to the present invention may be omitted.

  When the slot machine 1 is started with the setting key switch 92 turned on, the mode shifts to the setting change mode, in which the number of steps of the stepping motors constituting the reel motors 3ML, 3MC, 3MR in the storage area of the RAM 112 is set. Initialize all storage areas except the counter that counts and the stack area in use. In the setting change mode, when a new setting value is set by the setting switch 91, the new setting value is determined by operating the start lever 11, and then the setting key switch 92 is turned off. It will be a transition.

  On the other hand, when the slot machine 1 is started with the setting key switch 92 in the OFF state, it is diagnosed whether the data in the RAM 112 is damaged. If the data in the RAM 112 is damaged, a RAM abnormal error occurs. Shift to RAM error processing. The RAM error error processing cannot be canceled by operating the first reset switch 48 or the second reset switch 93, and the setting key switch 92 is turned on as described above to start the slot machine 1 again, and the set value is set again. It cannot be canceled without resetting.

  On the other hand, when an error related to the rotation of the reels 3L, 3C, 3R, an error related to winning determination, an error related to payout such as a hopper error, or the like occurs, the first reset switch 48 or the second reset switch It is possible to recover from these errors by the operation of 93.

  If the data in the RAM 112 is not damaged, that is, if the data obtained when the power of the slot machine 1 was turned off last time remains normal, the data stored in the RAM 112 remains unchanged. The processing shifts to the game control processing. That is, when the slot machine 1 is started with the setting key switch 92 turned off and the data in the RAM 112 is not broken, the game is resumed from the state at the time of the previous power failure of the slot machine 1.

  FIG. 18 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also performed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the processing of one game is started, first, an initial processing including a processing of clearing a predetermined area of the RAM 112 is performed (step S101).

  Next, the number of bets is set by operating the single BET button 14 or the MAX BET button 15 or by inserting medals from the medal insertion slot 13 and operating the start lever 11 to substantially execute the game. BET processing for instructing start is performed. (Step S102). In the BET processing, not only the number of bets is set but also the number of bets and credits already set can be settled by operating the adjustment button 16 to pay out the corresponding number of medals. When the number of bets has already been set and credit remains, the bet amount is settled by the first operation of the settlement button 16 and the credit is settled by the second operation.

  Further, in the slot machine 1 according to this embodiment, the number of bets for starting a game is limited to three, and the operation of the start lever 11 does not become effective until the number of bets is set to three. If the player has won the replay in the previous game, the same bet amount as in the previous game is automatically set by the replay game flag (the replay game flag is cleared at this stage).

  When the number of bets is set by the BET processing and the start lever 11 is operated, a random number for internal lottery is extracted, and based on the value of the extracted random number, the number of bets determined for each combination determined according to the gaming state and the number of bets is determined. A lottery process is performed to determine whether or not winning is permitted (step S103). In the lottery process, the number of determination values of the lottery target combination registered in the game state winning combination table of FIG. 17B is sequentially read in accordance with the game state, and is sequentially added to the extracted random numbers. Then, it is determined that the lottery target combination has been won when the result of the addition overflows.

  However, when the lottery target role is the challenge bonus (1) or the challenge bonus (2) in a state where the winning flag of the challenge bonus (1) or the challenge bonus (2) has been carried over from the game before the previous game, the overflow occurs. However, they will not be won again. If it is determined that a watermelon, a bell, a cherry, or a replay has been won while the winning flag of the challenge bonus (1) or the challenge bonus (2) has been carried over from the previous game, the watermelon, bell, cherry, or The replay winning flag is set again. When there is a lottery target combination determined to have been won in the lottery process, the winning flag is set in the RAM 112.

  Further, in the gaming state of the challenge bonus (that is, the value of the CB counter is larger than 0), regardless of whether the result of the internal lottery, that is, the result of the addition of the number of determination values overflows, the watermelon winning flag is stored in the RAM 112. , A bell winning flag and a cherry winning flag are set. When a single bonus or a replay has been won in the lottery, a watermelon winning flag, a bell winning flag, and a cherry winning flag are set to be superimposed on the winning flags of these combinations.

In addition, when the gaming state of the RT, that is, when the value of the RT counter is not 0, the player may win the challenge bonus (1) or the challenge bonus (2), whereby the value of the RT counter is initialized to 0. There is no. That is, even if the player wins the challenge bonus (1) or the challenge bonus (2), the gaming state of the RT is not ended.
Further, even if the player wins the challenge bonus (1) or the challenge bonus (2), the gaming state of the RT is not ended.

  When the lottery process ends, a reel rotation process is performed next (step S104). In the reel rotation process, the reel motor is operated on condition that the time counted by one game timer has elapsed a predetermined time (for example, 4.1 seconds) from the start of rotation of the reels 3L, 3C, and 3R in the previous game. 3ML, 3MC, and 3MR are driven, and rotation of all the left, middle, and right reels 3L, 3C, and 3R is started. When predetermined conditions (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reels 3L, 3C, 3R are established, the stop buttons 12L, 12C, 12R. Is enabled. Thereafter, when the player operates the stop buttons 12L, 12C, 12R, the reel motors 3ML, 3MC, 3MR are driven and stopped according to the stop control table selected according to the game state and the setting status of the winning flag, and the reel 3L is operated. , 3C and 3R are stopped.

  When the driving of the reels 3L, 3C, and 3R is stopped, a prize determination process is performed to determine whether any of the above-mentioned winning symbols is derived and displayed on any of the prize lines in the display mode at the time of the stop. (Step S105). If it is determined that any of the winning combinations has been won in the winning determination process, a process corresponding to the winning combination is performed. The details of the winning determination process will be described later.

  When the winning determination processing ends, a payout processing is performed (step S106). In the payout processing, if the winning combination flag of the small combination is set in the winning determination processing, the credit is increased by the number corresponding to the small combination. However, when the number of credits accumulated as data reaches 50, the excess number of medals is paid out from the medal payout opening 71 by driving the hopper motor 82. In addition, various processes not related to winning (for example, processes related to a challenge bonus, a single bonus, RT end control, and elimination of a winning flag without carryover) are also performed. At the end of the payout process, that is, at the end of one game, a game state command indicating the game state of the next game is sent to the effect control board 102. The details of the payout process will be described later. Then, the processing for one game ends, and the processing for the next one game starts.

  Next, the winning determination process in step S105 will be described in detail. FIG. 19 is a flowchart showing details of the winning determination process executed by the CPU 111 in step S105. In the winning determination process, the winning combinations according to the gaming state are sequentially read from the beginning (step S201). Next, it is determined whether or not the read symbol combination is aligned with any of the three winning lines of the variable display device 2 (step S202).

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

  If all of the winning combinations according to the gaming state are to be determined for winning, then it is determined whether or not a replay has been won based on whether or not a replay winning flag is set in the RAM 112 (step S205). If the player has won the replay, the in-replay game flag is set in the RAM 112 (step S206). This flag during the replay game is deleted when the bet amount is automatically set in the next game. Since the replay prize cannot occur at the same time as the single bonus prize, the process proceeds to step S213.

  If no replay has been won, it is determined whether or not the challenge bonus (1) has been won based on whether or not the winning flag of the challenge bonus (1) has been set in the RAM 112 (step S207). If the challenge bonus (1) has been won, the challenge bonus (1) winning flag set in the RAM 112 is deleted, and 30 is set as the initial value of the CB counter in the RAM 112. Here, the value of the RT counter is not initialized (step S208). Since the challenge bonus (1) prize cannot be generated at the same time as the single bonus prize, the process proceeds to step S213.

  If the challenge bonus (1) has not been won, it is determined whether or not the challenge bonus (2) has been won based on whether the winning flag of the challenge bonus (2) has been set in the RAM 112 (step S209). If the challenge bonus (2) has been won, the challenge bonus (2) winning flag set in the RAM 112 is deleted, and 150 is set as the initial value of the CB counter in the RAM 112. Here, the value of the RT counter is not initialized (step S210). Since the challenge bonus (2) winning cannot be generated at the same time as the single bonus winning, the process proceeds to step S213.

  If the challenge bonus (2) has not been won, it is determined whether a single bonus has been won based on whether or not a single bonus winning flag has been set in the RAM 112 (step S211). If a single bonus has not been won, the process directly proceeds to step S213.

  If a single bonus has been won, the gaming state of the next game is a single bonus regardless of whether the gaming state of the game is a single bonus. The single bonus winning flag is not deleted here, but is deleted in step S314 described later (step S212). Then, the process proceeds to step S214.

  In step S213, since the single bonus has not been won, regardless of whether the gaming state of the game is a single bonus, the gaming state of the next game is not a single bonus. Therefore, if the single bonus flag is set in the RAM 112, this flag is deleted. Even if the single bonus winning flag has been set but the single bonus has not been won, the single bonus winning flag is deleted in step S314 described later. Then, the process proceeds to step S214.

  In step S214, it is determined to which of the three winning lines of the variable display device 2 the RT symbol is derived. If the RT symbol has not been derived, the winning determination process is terminated and the process returns to the flowchart of FIG. If the RT symbol has been derived, it is determined whether or not the value of the RT counter of the RAM 112 is 0, that is, whether or not the game state of the current game is RT or other (step S215). If the game state of the current game is RT, even if the RT symbol is derived, the game state is not controlled from 1 again to RT, so that the winning determination processing is terminated and the process returns to the flowchart of FIG. .

  The RT symbol is derived, and if the current gaming state is not RT, 301 is set as the initial value of the RT counter (step S216). Here, the reason why the value of 301 is set as the initial value instead of 300 is that the value of the RT counter is decremented by one during the current game in step S311 described later. Then, the winning determination process ends, and the process returns to the flowchart of FIG.

  Next, the payout process in step S106 will be described in detail. FIG. 20 is a flowchart showing the payout process executed by the CPU 111 in step S106 in detail. In the payout process, it is determined whether or not there is a small winning combination with payout of medals based on whether a winning flag of watermelon or cherry is set in the RAM 112 (step S301). If the small winning combination has not been won, the process proceeds directly to step S303.

  If the winning combination is small, the hopper 80 is controlled to pay out the number of medals in order. However, until the number of credits stored as data reaches 50, the number of credits is increased instead of paying out medals (step S302). Then, the process proceeds to step S303.

  In step S303, the game state of the game is changed to the challenge bonus depending on whether the value of the CB counter of the RAM 112 is 0 and whether the winning flag of the challenge bonus (1) or the challenge bonus (2) is set in the RAM 112. Is determined. If the value of the CB counter is not 0 and the winning flag of the challenge bonus (1) or (2) is not set, it means that the gaming state of the game is the challenge bonus. If the gaming state of the game is not the challenge bonus, the process directly proceeds to step S312.

  If the gaming state of the game is the challenge bonus, it is determined whether the single bonus has been won in the game based on whether the single bonus winning flag is set in the RAM 112 (step S304). If the single bonus has been won in the game, regardless of whether a watermelon, a bell, or a cherry has been won, the game state of the challenge bonus ends only in the game, and the value of the CB counter is set to 0. (Step S305). Then, the process proceeds to step S312.

  If the single bonus has not been won in the game, it is determined whether or not the watermelon has been won based on whether or not the watermelon winning flag is set in the RAM 112 (step S306). If a watermelon has been won, the value of the CB counter of the RAM 112 is subtracted by 15 (until it becomes 0) (step S307). When the value of the result of the subtraction of the CB counter becomes 0, the gaming state of the challenge bonus ends at this point. Then, the process proceeds to step S312.

If the watermelon has not been won, it is determined whether or not the bell has been won, based on whether or not the bell winning flag has been set in the RAM 112 (step S308).
If the bell has been won, the value of the CB counter of the RAM 112 is reduced by 5 (until the value becomes 0) (step S309). When the value of the result of the subtraction of the CB counter becomes 0, the gaming state of the challenge bonus ends at this point. Then, the process proceeds to step S312.

  If no bell has been won, it is determined whether or not a cherry has been won this time, based on whether or not a cherry winning flag has been set in the RAM 112 (step S310). If a cherry has been won, the value of the CB counter of the RAM 112 is decremented by 2 (until it becomes 0) (step S311). When the value of the result of the subtraction of the CB counter becomes 0, the gaming state of the challenge bonus ends at this point. Then, the process proceeds to step S312. If no cherry has been won, the process directly proceeds to step S312 without decrementing the value of the CB counter (ie, the challenge bonus does not end at this point).

  In step S312, it is determined whether or not the value of the RT counter is 0, that is, whether or not the game state of the game is RT (however, it is not a challenge bonus). If the value of the RT counter is not 0, the value of the RT counter in the RAM 112 is decremented by 1 (step S313), and the process proceeds to step S314. If the value of the RT counter is 0, the process proceeds directly to step S314.

  In step S314, if a watermelon winning flag, a bell winning flag, a cherry winning flag, a replay winning flag, or a single bonus winning flag is set in the RAM 112, the flag is deleted. Here, the challenge bonus (1) winning flag and the challenge bonus (2) winning flag are carried over to the next game without being deleted. If a winning flag has been set in the RAM 112 in step S203, this is deleted. Then, the payout process ends, and the process returns to the flowchart of FIG. Here, when the process returns to the flowchart of FIG. 18, the process in the current one game ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 performs the transition of the game state among the normal game state, RT, single bonus, and challenge bonus, and issues a command according to the progress of the game. It is transmitted to the effect control board 102. On the other hand, the CPU 121 of the effect control board 102 independently performs various effect processing based on the command received from the game control board 101. The effect processing executed by the CPU 121 of the effect control board 102 is not directly related to the present invention, and thus detailed description is omitted.

  As described above, in the slot machine 1 according to this embodiment, when the player wins the challenge bonus or the challenge bonus (2) in the normal gaming state or RT (including the case where the bonus is controlled in conjunction with the single bonus), The gaming state is controlled to a challenge bonus. In the gaming state of the challenge bonus, the maximum stop delay time of the left reel 3L is reduced from the normal 190 milliseconds to 75 milliseconds, but the operation of the stop buttons 12L, 12C, and 12R is performed regardless of the result of the internal lottery. Depending on the procedure, a small watermelon, bell or cherry minor can be awarded.

  More specifically, assuming that the left stop button 12L is operated first, if the operation timing is the timing at which the 19th to 15th symbols on the left reel 3L are located in the lower row, 15 sheets are displayed. If the player wins the watermelon role and the 18th symbol is at the lower position, it wins the eight-page bell, and if the 16th or 17th symbol is at the lower position, 2 Wins a prize of cherry. Then, when the number of payout medals in the regular bonus reaches a specified number (30 or 150) due to the winning of these small roles, the gaming state of the regular bonus is ended.

  Also, in the challenge bonus, a single bonus may be won in the internal lottery, but when the single bonus is won, the gaming state of the challenge bonus is ended only in the game. However, when a single bonus is won in the game state of the challenge bonus, if the left stop button 12L is operated first and the reels 3L are operated at the timing when the 14th to 19th symbols are located at the lower stage, the RT symbol is changed. It is derived (the RT symbol cannot be derived except for the challenge bonus), and the gaming state is controlled to the RT.

  In other words, in the challenge bonus, when a single bonus is won, a chance to shift the gaming state to RT is obtained. However, as the number of games executed in the challenge bonus increases, the probability of winning the single bonus, that is, The probability of obtaining a chance to shift the gaming state to RT increases. Here, in order to increase the number of games to be executed with the challenge bonus, it is better to win the prize in the cherry of two roles instead of the watermelon of 15 roles. Although the number of games to be executed is further increased, it is meaningless because the RT symbols are not derived.

  In other words, in order to increase the chance that the gaming state is controlled to be RT by deriving the RT symbol based on the winning in the single bonus in the gaming state of the challenge bonus, the 16th or 17th reel is required for the left reel 3L. It is necessary to perform a game operation in which the left stop button 12L is operated first at the timing when the symbol is located at the lower stage. As described above, since the player's technical intervention acts on the control of the gaming state to the RT where the replay winning probability is high and the medal payout ratio exceeds 1, the interest of the game is improved. Can be.

  On the other hand, it is assumed that in the gaming state of the challenge bonus, the left stop button 12L is operated at the timing when the symbols Nos. 19 to 15 are located in the lower part of the left reel 3L, and the watermelon serving as the 15-sheet combination is awarded. Thus, the payout number of medals reaches the specified number with a small number of games. The smaller the number of digested games in the challenge bonus, the smaller the number of medals used for setting the number of bets, so considering only the gaming state of the challenge bonus, it is better for the player to win 15 watermelon pieces more and more. Greater profits can be obtained.

  For this reason, even if the chance of being controlled by the RT decreases, a large profit is obtained within the range of the gaming state of the challenge bonus, or the chance of being controlled by the RT is increased, and from the start of the challenge bonus to the end of the RT. Since there is room for the player to choose whether to obtain a large profit over a long period of time, the strategic nature in the game is extremely high, and the game can be further improved.

  Also, in the game state of the challenge bonus, even if it is possible to win the small role regardless of the result of the internal lottery, the maximum stop delay time of the left reel 3L is reduced to 75 milliseconds, and one frame is drawn. Since only the watermelon is recognized, the operation timing of the stop button 12L becomes more severe especially when aiming at the watermelon of 15 sheets. Also, with regard to the two-piece cherry, the aim must be determined while removing the watermelon and the bell within the pull-in range of one frame, so that the operation timing of the stop button 12L is also severe. As described above, the gaming state of the challenge bonus can be a gaming state in which the player has a very high level of technical intervention, so that the interest of the game can be further improved.

  Further, the operation timing of the stop button 12L for causing the watermelon to win in order to obtain a large profit only in the gaming state of the challenge bonus is 18 frames, which is the timing at which the 19th to 15th symbols are located at the lower stage of the left reel 3L. While there is a range of minutes, the operation timing of the stop button 12L for causing the cherry to win in order to increase the chance of being controlled by the RT is such that the 16th or 17th symbol is located at the lower stage of the left reel 3L. There is only a range of two frames called timing. As described above, if the player chooses to make a profit over a long period from the challenge bonus to the end of the RT, the difficulty of the technical intervention of the player becomes higher than simply making a profit with the challenge bonus alone. Therefore, the interest of the game can be further improved.

  In addition, in order to derive the RT symbol after the gaming state is controlled by the challenge bonus, it is necessary to first win the single bonus by an internal lottery. Here, when the left stop button 12L is operated first. It is also necessary that the operation timing is the timing at which the 16th or 17th symbol for the left reel 3L is located in the lower row. As a result, the player's technical intervention for controlling the game state to RT is further enhanced, so that the interest of the game can be further improved.

  In addition, the RT symbol is not a display mode of a winning combination, but a loss display mode that can be derived by dropping the single bonus which is a winning combination when the winning is won. At the time of winning the single bonus, the single game can be directly won and the next game can be played in the single bonus gaming state. However, it is more preferable for the player to derive the RT symbol and play the subsequent game at the RT. Many benefits can be obtained. In order for the game state to be controlled by the RT as described above, it is necessary to perform a stop operation so as to intentionally miss the winning role in the internal lottery, and such technical intervention becomes interesting.

  By the way, if a single bonus is won in the gaming state of the challenge bonus, the challenge bonus is ended there and a chance to control the RT is obtained.However, whether or not the single bonus has been won is determined by the player. It will not be announced. That is, the player does not know at all whether the RT symbol can be derived until one of the stop buttons 12L, 12C, and 12R is operated. In particular, when the left stop button 12L is operated first, if "BAR" which is a symbol constituting the display mode of the single bonus is derived, "watermelon" is also derived at the same time, and the symbol constituting the RT symbol is derived. If a certain "red 7" is derived, it means that "cherry" is also derived at the same time.

  In this way, even if the player wins the single bonus in the game state of the challenge bonus and dares to omit it, the RT symbol is derived, and at the same time, the player's first aim, cherry, is also won. Therefore, by attracting the player's attention to the winning of the cherry, it is possible to prevent the player from being informed as much as possible that the gaming state of the challenge bonus is ended by the winning of the single bonus.

  Furthermore, even when the player cannot derive the RT symbol, only one "BAR" is arranged on the left reel 3L, that is, only "20" is arranged at intervals of 20 frames. On the other hand, the "BAR" can be derived within the range of the maximum stop delay time of 75 milliseconds in the gaming state of the challenge bonus when the left stop button 12L is operated first. There is only a range of four frames, that is, the timing when the symbols # 13 to # 13 are located at the bottom.

  Also, the pull-in of “BAR” is performed only for one frame, and it is very difficult to know whether the pull-in control of “BAR” has been performed based on the winning of the single bonus. Further, even if "BAR" is derived, "watermelon" is always derived at the same time, and accordingly, depending on the operation timing of the middle and right stop buttons 12C and 12R, watermelon is won. As described above, the pull-in control of “BAR” is difficult to understand, and the chance of winning the single bonus is extremely small. Therefore, it is difficult for the player to detect the end of the gaming state of the challenge bonus by winning the single bonus as much as possible. You can do so.

  The operation procedure for deriving the RT symbol when the single bonus is won in the challenge bonus is based on the assumption that the left stop button 12L is operated first, and the 16th or 17th reel is used for the left reel 3L. The operation is performed at the timing when the number symbol is located at the lower stage, and completely coincides with the operation timing for causing the cherry to win in the challenge bonus. For this reason, as long as the player plays the game while aiming for the cherry in the challenge bonus, the player derives the RT symbol at the time of winning the single bonus without paying attention to whether or not the single bonus has been won, and causes the RT to play the game state. May be controlled.

  Also, there are two types of roles for causing the challenge bonus to control the gaming state, the challenge bonus (1) and the challenge bonus (2), and the number of medals paid out for which the single bonus controlled based on each is completed. Are different from 30 and 150. The symbol configuration differs between the challenge bonus (1) and the challenge bonus (2), and the difference in the number of paid-out medals, which is a condition for ending the single bonus, is different for the player in conjunction with the display result derived on the variable display device 2. It will be easy to understand. In addition, the control of the RT is linked to the display result of the variable display device 2 called the RT surface, so that the control is easy for the player to understand.

  In addition, since the gaming state of the challenge bonus based on the winning of the challenge bonus (1) and the gaming state of the challenge bonus based on the winning of the challenge bonus (2), there is a difference in the number of medals to be paid out as an end condition. If the same type of small win is won in each game, the number of games that can be executed by each end differs. Then, the probability of winning the single bonus before the game state of the challenge bonus is ended is different depending on the challenge bonus based on any of the winnings, and there is also a difference in the possibility that a chance to control the RT is generated. Therefore, the interest of the game can be further improved.

  By the way, the challenge bonus (1) and the challenge bonus (2) are also subjected to internal lottery in the RT, and even if they are won in the RT, the gaming state of the RT is ended here. There is no. However, in the challenge bonus controlled from the RT, even if the RT symbol is derived, the RT of the 300 games does not start again from that.

  Therefore, in the challenge bonus controlled from the RT, it is more profitable for the player to make the watermelon which is the 15-copies win more and more. Even if the game is controlled to the same challenge bonus as described above, the player can obtain a larger profit by changing the game operation depending on whether the game is controlled from the normal game state or from the RT. The most advantageous game operation patterns are increased, and the interest of the game can be further improved.

  Further, not only is the RT not terminated by winning the challenge bonus (1) or the challenge bonus (2), but the RT is not terminated by winning of these roles, so that the RT is more advantageous to the player. Game state, and a profit for 300 games can be reliably obtained. Since the RT becomes a more advantageous game state for the player, the option of obtaining the profit including the RT up to the RT is more important than simply trying to obtain the profit only by the challenge bonus. The aim can be further refined.

  At the same time, giving a watermelon a prize in a game in the game state of the challenge bonus controlled from the normal game state seems to be seemingly meaningless at first glance, since it greatly reduces the chance that the game state is controlled by the RT. It is. However, by giving the cherries a prize, the chances of being controlled by the RT are increased, and many profits can be obtained by the time the RT is completed, but this is a very large amount of 15 games + 300 games. The benefits that are gained over a long period of time, the short-term gains are very small and are still rather negative early in RT.

  For example, if it is considered that the number of games that are likely to be completed before closing even if the player wins the challenge bonus (1) or the challenge bonus (2) in the time zone immediately before the closing of the amusement store, the watermelon, which is 15 sheets, Players who win more and more wins will benefit players. In addition, since the operation timing of the stop button 12L that allows the watermelon to win can be as long as 18 frames, the time required to complete one game can be shortened. Aiming for the watermelon with the challenge bonus in this way can also be a meaningful strategy, so that the player's options in the game increase both in name and substance, and the interest of the game can be further improved.

  The RAM 112 of the game control board 101 is initialized by changing the set value, but the value of the counter for counting the number of steps of the stepping motors constituting the reel motors 3ML, 3MC, 3MR is not initialized. . For this reason, even after the setting value is changed, the number of steps (the number of steps counted by the counter of the RAM 112) of the stepping motors constituting the reel motors 3ML, 3MC, and 3MR recognized by the CPU 111 is different from the actual number of steps. It is possible to prevent the player from noticing that the reels 3L, 3C, 3R cannot start rotating smoothly due to the different excitation phases of the pulse signals and the set values are changed. .

It is checked once a game whether or not the overflow tank 90 is full by the full tank sensor 90. If the full tank is detected, the overflow tank is controlled to a full error. However, this check is not performed when a replay winning is made in the previous game (that is, when the in-replay game flag is set in the RAM 112).
If the player has won the replay in the previous game, the number of bets is set without the player inserting a medal. Can be reduced.

  The external output board 105 also outputs a signal during a challenge bonus, a signal during a single bonus, a reel control signal, a stop switch signal, a medal IN signal, a medal OUT signal, a winning status signal, and a security signal to an external computer such as a hall management computer. Output to the device. Here, the security signal includes a door opening signal, a set value change signal, a closing error signal, a dispensing error signal, another error signal, and a signal during settlement, which are serially transmitted from the same output terminal in a time-division manner. Is output to As described above, a plurality of types of security signals are output in a time-division manner. For example, a semiconductor chip mounted on the external output substrate 105 for outputting various signals can be reduced in size.

  In addition, since the security signal includes a signal during settlement, by monitoring this signal with an external device, it can be grasped that the settlement of medals according to the credit or the number of wagers is performed, and the The clerk of the game store can easily detect that such misconduct has been performed. Furthermore, since the security signal includes the insertion error signal and the payout error signal, even if the clerk of the game store does not notice the error signal, by monitoring these with an external device, the game can be performed without playing the game. The clerk of the game store can easily detect that an act of illegally obtaining a medal (an act of illegally inserting a medal from the medal slot 13 or removing a medal from the hopper 80) is also performed. become able to.

  In addition, since the security signal includes the setting value change signal, by monitoring this with an external device, it is possible to grasp that the setting value is being changed, and it is possible to grasp that the setting value is changed. The clerk of the game store can detect that the misconduct has been performed. Further, since the security signal includes a door opening signal, it is also known that an act of illegally operating the setting switch 91 that can be operated by opening the front door is performed. The clerk can easily detect.

  Further, a backup power supply is mounted on the external output board 105, and even when the power of the slot machine 1 is turned off, the front door is opened by the door open sensor 95 by supplying power from the backup power supply. It is capable of detecting the state and outputting a security signal including a door open signal to an external device. Even when the power of the slot machine 1 is turned off and the game is not performed, the semiconductor chips constituting the control unit 110 of the game control board 101 and the control unit 120 of the effect control board 102 are replaced with non-genuine products. A game store clerk can easily detect that illegal acts such as attaching an internal signal to the semiconductor chip for extracting internal signals that are not originally output to the outside are performed. Become.

  Further, the security signal also includes another error signal indicating that an error other than the input error and the payout error has occurred. The errors other than the insertion error and the payout error do not directly occur in an attempt to increase the number of medals. However, when the error occurs, there is a possibility that some wrongdoing has been performed. Further, if the notification is made while the error has occurred, the player cannot play the game. By monitoring other error signals included in the security signal with the external device, the clerk of the game store can easily detect a fraud and restart the game early.

  The external output board 105 outputs a medal IN signal collectively when the start lever 11 is operated. If the medal IN signal is output every time a medal set as the number of bets is inserted, if the set bet amount is canceled by operating the settlement button 16, the output medal IN signal needs to be canceled. Will be. A medal IN signal is output when the bet amount is set from the credit by operating the single BET button 14 or the MAXBET button 15 and when the actual bet is inserted from the medal slot 13 and the bet amount is set. Programs are required separately. By outputting the medal IN signal collectively when the start lever 11 is operated as in the slot machine 1 according to this embodiment, such inconvenience can be prevented.

  On the other hand, the external output board 105 outputs a medal OUT signal every time one medal is paid out from the hopper 80. If medals OUT signals are to be output collectively for the number of medals to be paid out when paying out medals based on the small prize winning, when a medal out error occurs in the hopper 80, the actual An error occurs between the paid-out medals. Further, when the medal OUT signals are output at the same time as the number of paid out medals at the end of the payout of the medals, it is possible that the output of the medal OUT signals is continued even after the next game is started. Nature occurs. By outputting the medal OUT signal every time one medal is paid out from the hopper 80 as in the slot machine 1 according to this embodiment, such inconvenience can be prevented.

  In addition, various commands are transmitted from the game control board 101 to the effect control board 102 in accordance with the progress of the game. However, the commands are transmitted more than the command transmission buffer provided in the RAM 112 of the game control board 101. The capacity of the command receiving buffer provided in the RAM 122 of the effect control board 102 is larger. For this reason, even if a large amount of commands are sent at once from the game control board 101, the effect control board 102 can sufficiently store unprocessed commands, so that the CPU 121 of the effect control board 102 It is possible to prevent the occurrence of a command that cannot be performed, thereby hindering the execution of the effect.

  In the slot machine 1 according to this embodiment, the connector control member 500 including the mounting side member 510 and the connector cover 520 is attached to the board case 200, so that the game control board accommodated in the board case 200 can be mounted. The removal of the board-side connector 620a and the cable-side connector 610a is restricted, and in this state, the board case 200 is mounted on the mounting base 250 and the fixing member 255 and the sealing piece 232 are fixed, so that the board case 200 is removed from the board case 200. The removal of the connector restricting member 500 is restricted, and if the sealing piece 232 of the board case 200 is broken to release the adhesion between the board case 200 and the housing (the mounting base 250), the board-side connector The cable-side connector 610a cannot be removed from the 620a. That is, the cable-side connector 610a cannot be pulled out without leaving a trace of breakage of the sealing piece 232, and it becomes impossible to connect an unauthorized device such as a driving device without leaving a trace. You will be able to discover what you may have done.

  When replacing the game control board 101 together with the board case 200 accommodating the game control board 101 due to a failure or the like, the sealing piece 232 is broken and the board case 200 and the housing (the mounting base 250) are fixed. When released, the connector restricting member 500 can be detached from the board case 200 and the cable-side connector 610a can be detached from the board-side connector 620a. The cable side connector 610a can be separated from the board side connector 620a without opening.

  Further, the connector regulating member 500 is composed of a mounting member 510 and a connector cover 520. After the mounting member 510 is mounted on the board case 200, the cable connector 610a is connected to the board connector 620a. By attaching the connector 620a to the attachment member 510 so as to cover a part of the connector 620a from above, the cable connector 610a cannot be disconnected from the board connector 620a. Is connected to the board-side connector 620a, and the locking cylinder 522 of the connector cover 520 is fitted into the locking hole 513a of the locking hole 513 of the mounting-side member 510 located around the board-side connector 620a. The connector cover 520 is simply attached to the attachment side member 510. Since the cable-side connector 610a is partially covered and the movement of the cable-side connector 610a in the pulling-out direction is regulated, the assembly work is reduced in restricting the removal of the cable-side connector 610a from the board-side connector 620a. it can.

  Even when the game control board 101 is housed in the board case 200, it is only necessary to connect the cable-side connector 610a to the board-side connector 620a as it is and then attach the connector cover 520. In this case, in restricting removal of the cable-side connector 610a from the board-side connector 620a, the assembling work can be reduced more effectively.

  Further, since the connector cover 510 does not cover the entire connection portion between the cable-side connector 610a and the board-side connector 620a, it covers only a part of the cable-side connector 610a on the pulling-out side. Not only can the removal of the connector 610a from the board-side connector 620a be reliably controlled, but also the material required for manufacturing the connector cover 510 can be reduced.

  Further, the connector cover 520 is attached to the attachment-side member 510 with only one locking cylinder 522, but one side wall of the connector cover 520 has a rib abutting on the surface of the base piece 510 a of the attachment-side member 510. Since 521b and 521b are formed and the movement of the connector cover 520 is regulated, the removal of the cable-side connector 610a from the board-side connector 620a can be reliably regulated.

  Further, inward locking portions 511 and 511 are formed at both ends of the mounting-side member 510 extending from the base piece 510a, respectively, and the locking portions 511 and 511 are elastically deformed outward. In this state, the mounting member 510 can be attached to the substrate case 200 by being assembled to the substrate case 200 and engaging with the locking grooves 514, 514 formed on the back surface of the substrate case 200. When attaching the member 500 to the board case 200, the member 500 can be attached without using other members such as screws and pins, so that the number of components can be reduced.

  When the attachment-side member 510 constituting the connector restricting member 500 is attached to the board case 200, the base piece 510a and the upper pieces 510c, 510c of the attachment-side member 510 face the steps facing the board case 200 at the step in the upper case 203. The upper surface of the portion 203b and the lower surface of the concave portion 203f are respectively in contact with each other, so that it is possible to effectively prevent an unauthorized component or the like from being attached between the connector regulating member 500 and the surface of the board case 200.

  In addition, since the attachment-side member 510 and the connector cover 520 constituting the connector regulating member 500 are both made of a transparent synthetic resin material, the visibility inside the board case 200 may be impaired by the connector regulating member 500. Since the game control board 101 is not disturbed, there is no trouble in monitoring the game control board 101. Further, even if an unauthorized component is attached to the gap between the connector regulating member 500 and the board case 200, it can be easily found.

  Further, connector connection between the game control board 101 and the inserted medal sensor 44, that is, connection between the board side connector 620a of the game control board 101 and the cable side connector 610a of the cable 600a, and connection between the cable side connector 611a of the cable 600a and the operation unit The connection between the board-side connector 621a of the relay board 107 and the connection between the board-side connector 622g of the operation unit relay board 107 and the cable-side connector 612g of the cable 601g is released by the connector control member 500 and the connector control. It is regulated by a member 650. As a result, one of the connectors between the game control board 101 and the inserted medal sensor 44 is replaced with a connector such as an unauthorized driving tool and connected, and a signal related to the progress of the game is sent to the game control unit 110 of the game control board 101. It is difficult to perform an illegal act such as illegally inputting / outputting information, so that it is possible to effectively prevent the execution of illegal business.

  In order to release the connector connection between the game control board 101 and the inserted medal sensor 44, the sealing piece 232 of the board case 200, the connecting piece 522a of the connector cover 520, and the connecting piece 684a of the cover member 680 are broken. Therefore, if at least one connector connection between the game control board 101 and the inserted medal sensor 44 is released, the trace remains and it is extremely difficult to erase the trace. In addition, the above-mentioned fraudulent acts can be suppressed more effectively.

  Although only one relay board is provided between the game control board 101 and the inserted medal sensor 44, when passing through a plurality of relay boards, it is necessary to restrict withdrawal of all connector connections existing therebetween. In this manner, any one of the connectors between the game control board 101 and the inserted medal sensor 44 is replaced with a connector such as an unauthorized driving tool and connected, and is connected to the game control unit 110 of the game control board 101. Since it becomes difficult to perform an illegal act such as illegally inputting / outputting a signal relating to the progress of the game, it is possible to effectively prevent the execution of illegal business.

  Also, the first electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 81 for inputting signals to the game control board 101 in accordance with the progress of the game and the progress of the game Of the second electronic components 3ML, 3MC, 3MR and 82 for which a signal is output from the game control board 101 in response to the connector, only the connector connection between the inserted medal sensor 44 and the game control board 101 is provided with a connector restricting member. It regulates the release of connections between each other. That is, the medal sensor 44 in which the game cannot proceed without the signal (the bet amount cannot be set and the game cannot be started unless the signal from the medal sensor 44 is input) and the game control. A connector restricting member is provided only for the connector connection between the board 101 and the release of the connection between the connectors is regulated, and the connection between the connectors is released between another electronic component and the game control board 101 so that the driving tool is driven. Even if the connector is replaced, the game can not automatically proceed in the game substantially, so it is possible to prevent fraud with a minimum regulation, and to disconnect these connectors Parts can be reduced.

  In addition, a plurality of signal lines connecting the game control unit 110 and a plurality of electronic components for inputting and outputting signals necessary for the progress of the game are provided between the game control board 101 and the operation unit relay board 107 by one. Is connected by the cable 600a of the game control board 101, the connector connection between the board-side connector 610a of the game control board 101 and the cable-side connector 620a, that is, the release of connection at only one connector connection is regulated, so that a plurality of signal lines are connected to each other. Can be restricted, and it is not necessary to prepare a plurality of components for restricting the release of the connector connection, and the number of these components can be reduced.

  Even when a plurality of signal lines connecting the game control unit 110 and a plurality of electronic components for inputting and outputting signals necessary for the progress of the game are connected via a plurality of cables, the board-side connector is brought close to the plurality of signal lines. In addition, it is necessary to prepare a plurality of components for restricting the disconnection of these connector connections by disposing them at the same position and restricting the release of the connection between the plurality of board-side connectors and the plurality of cable-side connectors with one component. And the number of these components can be reduced.

  Further, the connection between the cable side connector 611a of the cable 600a connecting the game control board 101 and the operation unit relay board 107 and the board side connector 621a of the operation unit relay board 107 is released, and the operation unit relay board 107 and the inserted medal sensor 44 are released. The connection between the cable-side connector 612g of the cable 601g and the board-side connector 622g of the operation unit relay board 107 is simultaneously restricted by one connector restricting member 650. It is not necessary to prepare a plurality of components for regulating the number of components, and the number of these components can be reduced.

  Further, after the backup power supply of the game control unit 110 passes from the game control board 101 via the cable 600a, the operation unit relay board 107, the cable 601g, the inserted medal sensor 44, the cable 601g, the operation unit relay board 107, and the cable 600a, When the power supply to the slot machine 1 is cut off, the connection between the board-side connector 620a of the game control board 101 and the cable-side connector 610a of the cable 600a is performed. Between the cable-side connector 611a of the operation unit relay board 107 and the board-side connector 621a of the operation unit relay board 107, and the connection between the board-side connector 622g of the operation unit relay board 107 and the cable-side connector 612g of the cable 601g. By the backup power Supply line is disconnected, it can not hold data RAM112 the game control unit 110, so that the lost. That is, when the connection between the connectors between the game control board 101 and the inserted medal sensor 44 is released at any one point, the backup data stored in the RAM 112 of the game control unit 110 is lost.

  On the other hand, in order to connect an unauthorized device such as a driving device, it is necessary to connect and disconnect the connector, but even if you use the driving device and improperly set a special role or play state, replace it with a regular connector Therefore, the data in the RAM 112 is initialized by canceling the connection of the connector, so that the slot machine 1 in which the special role has been won or the gaming state which is advantageous to the player is set using the driving tool, It is possible to prevent illegal business, such as providing the game to a player when the store starts operating.

  The present invention is not limited to the above 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-described embodiment, the engaging portions 511 and 511 of the attachment-side member 510 are elastically deformed outward and engaged with the engaging grooves 514 and 514 formed on the back surface of the substrate case 200. When the mounting member 510 is mounted on the substrate case 200 and the substrate case 200 on which the mounting side member 510 is mounted is fixed to the mounting base 250 (housing) so as not to be detachable, the side pieces of the mounting side member 510 are mounted. 510 d, 510 d abut against the inner surfaces of the side walls 250 b, 250 c of the mounting base 250, and are clamped to restrict outward deformation of both side pieces 510 d, 510 d of the mounting side member 510. In this configuration, it is impossible to remove the case 200 from the case 200.

  On the other hand, for example, when a part of the mounting side member is fixed on the back surface of the substrate case 200 with a screw or a removable locking pin, and the substrate case 200 is irremovably mounted on the housing (mounting base). Alternatively, the structure may be such that these screws and locking pins are concealed, and the board case 200 may be attached to the housing so that removal of the attachment-side member from the board case 200 may be restricted. In addition, if the mounting side member is attached to the board case 200 and the board case 200 is fixed to the housing, the mounting side member cannot be removed from the board case 200. May be adopted.

  In the above-described embodiment, the connector cover 520 is attached to the attachment-side member 510 with only one locking cylinder 522. This configuration is preferable in that the structures of the connector cover 520 and the attachment-side member 510 can be simplified. On the other hand, a plurality of locking cylinders 522 are provided on the connector cover 520, and locking holes 513a are provided at corresponding locations on the mounting member 510, respectively. You may make it attach it. By doing so, the removal of the cable-side connector 610a from the board-side connector 620a can be more firmly restricted. Further, in this case, it is preferable to attach the connector cover 520 to the attachment-side member 510 at a plurality of locations at a plurality of locations straddling the connection between the cable-side connector 610a and the board-side connector 620a. The removal of the cable-side connector 610a from the board-side connector 620a can be more firmly restricted.

  In the above embodiment, only the connector connection between the inserted medal sensor 44 and the game control board 101 is provided with the connector restricting member to restrict the disconnection of the connectors. On the other hand, a connector restricting member may be provided only for the connector connection between the start switch 41 and the game control board 101 to restrict the disconnection of the connectors. If the reel does not stop until the reel is stopped after the rotation of the reel is started, only the connector connection between any of the stop switches 42L, 42C, and 42R and the game control board 101 is restricted. A member may be provided to regulate release of the connection between the connectors. In these cases, the same effects as those of the above-described embodiment can be obtained.

  In the above embodiment, the backup power supply returns from the game control board 101 to the game control board 101 via the inserted medal sensor 44 again, and is supplied to the game control unit 110, so that the connector connection therebetween is established. When released, data in the RAM 112 is lost. On the other hand, an electronic component (for example, a start switch 41 or a component which does not stop the reels until the reels are stopped after the rotation of the reels is started) is used to input and output signals necessary for the progress of the game. , The stop switch 42L, 42C, 42R, etc.), the same effect as in the above embodiment can be obtained.

  In addition, a capacitor or a battery for accumulating a backup power supply is mounted on a mounting board for electronic components for inputting and outputting signals necessary for the progress of the game, and a relay board for these electronic components (such as the operation unit relay board 107). A backup power supply line from a capacitor or a battery mounted on the mounting board or the relay board is connected to a game control board via a cable together with a signal line of an electronic component and supplied to the game control unit 110. You may make it so. Even in this case, the data in the RAM 112 is lost when the connector connection between the mounting board or the relay board and the game control board 101 is released. Since the backup power is supplied to the control board 101 from a capacitor or a battery mounted on the mounting board or the relay board via a cable, the backup power is supplied to the game control unit 110 when the cable is disconnected. In order to continue to supply power, it is necessary to short-circuit the backup power supply line across the boards, and it is very difficult to disconnect the connector while the backup power is being supplied. Connection can be effectively prevented.

  Also, for example, a signal output circuit that always outputs a specific signal even at the time of a power failure is mounted, and at the time of a power failure, a specific signal is always detected. Is mounted on the game control board 101, and the output path of this specific signal is transmitted from the game control board 101 to the electronic control unit through which electronic signals necessary for the progress of the game are input and output. Returning to the substrate 101, it is configured to be input to the signal monitoring circuit, and at the time of starting the game control unit 110, it is checked whether or not the signal monitoring circuit stores that the detection of the specific signal is interrupted, and the specific signal is The data stored in the RAM 112 may be cleared when it is stored that the detection has been interrupted. Even in such a case, it is possible to prevent illegal business such as providing the slot machine 1 set in a state where the special role has been won by using the driving tool to the game player at the start of business of the game store or the like.

  In the above embodiment, when the slot machine 1 is started without turning on the setting key switch 92, unless the data in the RAM 112 is destroyed, the RAM 112 is used to return to the state before the power failure. And had Here, when the game control unit 110 is restored to the state before the power interruption when the game control unit 110 is started, the CPU 111 transmits a power-on command indicating the winning state of the special role and the game state, and the CPU 121 of the effect control unit 120 When the insertion command is received, the winning status and the gaming status of the special combination may be notified on the liquid crystal display 4, the number-of-payouts display 51, the credit display 52, and the payout display 53.

  In order to connect an unauthorized device such as a driving device, it is necessary to turn off the power once (unplugging the connector without turning off the power may cause a failure). In this case, forcibly disconnect the connector and disconnect it. Even if the driving tool is used to improperly win the special role or set a game state advantageous to the player, when the game control unit 110 is restarted, the fact that the special role has been won or the advantageous game Since it can be easily determined from the outside that the game machine is controlled to the state, the slot machine 1 in which the special role has been won using the driving tool or the gaming state that is advantageous to the player is set in the game store business. Unauthorized business, such as providing the game to a player at the start, can be effectively suppressed.

  In the above embodiment, the operation timing of the stop button 12L for winning the cherry in the challenge bonus completely matches the operation timing for deriving the RT symbol at the time of winning the single bonus (however, the left timing) If the stop button 12L is operated first), if a cherry is aimed at in the challenge bonus, the RT symbol can be derived at the time of the single bonus winning without knowing the winning of the single bonus. I was For this reason, the winning of the single bonus is not notified to the player at least until the end of the game.

  On the other hand, when, for example, “White 7-JAC-JAC” is applied as the RT symbol, the operation timing of the stop button 12L for causing the cherry to win in the challenge bonus derives the RT symbol when the single bonus is won. Operation timing is exclusive. In this case, if the single bonus is won, before the stop buttons 12L, 12C, and 12R are operated, the image displayed on the liquid crystal display 4 and the sound output from the speakers 7L, 7R, and 7U indicate that. The information may be notified to the player.

  In this case, even if the player performs the stop operation to make the cherry win in the challenge bonus in order to increase the probability of winning the single bonus and increase the chance that the game state is controlled by the RT, When the gaming state of the challenge bonus is completed by winning the bonus, the stop buttons 12L, 12C, 12R can be operated so as to derive the RT symbol according to the notified information.

  In the above embodiment, the RT symbol that causes the RT to control the gaming state is not defined as the display mode of the winning combination, but is a display mode that can be derived by missing the single bonus as the winning combination. . On the other hand, the RT symbol may be a lottery target combination in the gaming state of the challenge bonus, and may be a display mode of a winning combination (for example, special replay) that ends the gaming state of the challenge bonus by winning.

  In the above-described embodiment, the RT game state is controlled only for 300 games after the RT symbol is derived, but the RT symbol is derived when the game is already in the RT gaming state. Also, the gaming state was not controlled from 1 to RT again. On the other hand, even when the RT symbol is derived in the RT gaming state, 301 may be set as the initial value of the RT counter regardless of the value of the RT counter at that time. Further, when the RT symbol is derived in the RT gaming state, a predetermined value (or 300) may be added to the value of the RT counter to increase the number of RT continuous games.

  In addition, the termination condition of the game state of the RT is not limited to the one defined by the number of games as described above, and may be a cumulative number of medals paid out to the player after the game state is controlled by the RT, or the payout number. The number of net medals obtained by subtracting the number of medals used for setting the number of bets from the accumulated number of medals may be determined to have reached a predetermined value.

  In the above embodiment, the single bonus is won in the gaming state of the challenge bonus, and the gaming state is controlled to the RT by deriving the RT symbol by missing the bonus. In this RT, the game state may be controlled to AT. Alternatively, in such a case, the game state may be controlled by the AT instead of the RT.

  In the above embodiment, the RT controlled by the derivation of the RT symbol cannot be ended only by winning the challenge bonus (1) or the challenge bonus (2), and of course, the challenge bonus (1) or the challenge bonus Even if the player wins the game in (2), the game is not ended, and the game is continuously controlled until the game 300 is completed (however, the challenge bonus controlled during the RT is not counted).

  On the other hand, when a specific combination is won, the gaming state of the RT may be ended. This specific combination can be a combination with a missing portion by operating the stop buttons 12L, 12C, 12R, and may be a challenge bonus (1) and / or a challenge bonus (2) or any other combination. It may be a small role or a replaying role different from each role shown in the above embodiment.

  Here, if the specific combination is a combination that is missing according to the operation procedure of the stop buttons 12L, 12C, and 12R, and if the player can intentionally skip this while winning the specific combination, RT Can be continued up to the completion of 300 games without terminating the gaming state. Therefore, when the gaming state is controlled by the RT, when the player wins the specific combination, the information that can be specified to that effect is displayed on the liquid crystal display 4 by an image displayed on the liquid crystal display 4 or by a sound output from the speakers 7L, 7R, and 7U. The information may be notified to the player.

  The right (navigation right) to be notified of information that can specify that the specific combination has been won can be given when the player clears a predetermined mission in the challenge bonus immediately before being controlled by the RT. . Even if the mission is cleared during the challenge bonus, the single bonus is not won, and if the game state is not controlled by the RT, even if the navigation right granted there is invalidated, the next challenge bonus is performed. , A single bonus may be won, and the RT symbol may be derived based on the single bonus to carry over to the controlled RT.

  As a mission to be set during the challenge bonus, for example, the display result of the loss may be derived without causing any small role to win. However, the mission imposed on the player during the challenge bonus is not limited to this, and there may be a plurality of types of missions. When there are a plurality of types of missions, the player may be able to select a mission imposed by his / her operation at the start of the challenge bonus.

  As described above, when the navigation right is granted in the RT, the player operates the stop buttons 12L, 12C, and 12R so as not to win the specific combination according to the information notified when the specific combination is won. , RT are not terminated. As described above, the player can intervene in the game by his / her own operation with respect to the continuation of the RT in which the medal payout rate exceeds 1 and the game state is advantageous to the player, and the interest of the game can be improved. Furthermore, by allowing the player to select the type of mission to be imposed, the player's sense of intervention in the game can be further increased, and thereby the interest of the game can be improved.

  It should be noted that the navigation right is granted each time a mission is completed. For example, if it is assumed that the navigation right of 5 games is granted by clearing one mission, the player clears one mission. If you win 50 games in RT, or if you complete 3 missions, you finish 150 games in RT, and if you win a special role, you will be notified of information that can specify that fact. be able to. Alternatively, in the case where one navigation right is granted in one mission, if the player has completed three missions, the specific role will be retained until the specific role is won five times in RT. Information that can specify that the game has been won can be notified.

  Also, in addition to the advantageous RT in which the medal payout rate exceeds 1 as in the RT according to the above-described embodiment (RT having a replay winning probability as high as the RT in the above-described embodiment), the medal payout rate Provides a disadvantageous RT that is not much different from the normal game state (for example, an RT in which the number of replay determination values changes only by one from the normal game state), and determines whether the advantageous RT depends on the display mode derived in the normal game state. It may be controlled to any of the disadvantageous RTs. The number of continued games at the disadvantageous RT can also be a predetermined number of games.

  The display mode of the winning combination can be applied to such a disadvantageous RT symbol for controlling the gaming state by the disadvantageous RT, but the single bonus in the above embodiment is set to the single bonus (1), which is different from the single bonus. A single bonus (2) (for example, “BAR-BAR-white 7”) is defined, and a disadvantageous RT symbol (for example, “red 7-bell-bell”) is derived by missing the single bonus (2). It is also possible to apply the display mode of the winning combination to one of the advantageous RT symbols.When the advantageous RT symbol and the disadvantageous RT symbol are displayed as the winning combination, the stop buttons 12L, 12C, and 12R are also included. It can be determined that there is a dropout depending on the operation procedure.

  In addition, when winning a role that enables the derivation of the advantageous RT symbol and / or a role that enables the derivation of the disadvantageous RT symbol in the single bonus, the player is notified of information that can specify that fact. can do. The player has also cleared a predetermined mission with respect to the right to be notified of the information that can specify that the winning combination of the advantageous RT symbol can be derived and / or the combination capable of deriving the disadvantageous RT symbol. It can be given at times. In this case, the navigation right and the mission for granting the navigation right may be the same as the navigation right for notifying the winning of the specific role that terminates the advantageous RT described above and the mission for granting the same. it can.

  Further, the advantageous RT symbol and the disadvantageous RT symbol are not derived according to the lottery result in the single bonus and are controlled to the advantageous RT and the disadvantageous RT, but are not controlled to the advantageous RT symbol and the disadvantageous RT symbol, but are performed in the normal game state. The symbol and the unfavorable RT symbol are not derived by missing the single bonus, but may be controlled to be either the advantageous RT or the unfavorable RT depending on which of the predetermined winning combinations is derived first. it can.

  As described above, when the navigation right is granted in the normal gaming state, the player wins a role that enables the derivation of the advantageous RT symbol and / or a role that enables the derivation of the disadvantageous RT symbol. By operating the stop buttons 12L, 12C, 12R so as to derive the advantageous RT symbol in accordance with the information notified to the user, and not to derive the disadvantageous RT symbol, control the advantageous RT and prevent the disadvantageous RT from being controlled. can do. As described above, the player can intervene in the game by his / her own operation with respect to the control of the advantageous RT and the disadvantageous RT, thereby improving the interest of the game.

In the above-described embodiment, only the challenge bonus, the single bonus, and the RT are provided as game states different from the normal game state. On the other hand, when the player wins the challenge bonus (1) or the challenge bonus (2), the game state is controlled to AT (Assist Time) until the specified number of games (for example, 30 games) is exhausted thereafter. It may be.

  In the AT gaming state, when a winning combination is won in accordance with the operation procedure of the stop buttons 12L, 12C, 12R, the type of the winning combination is notified to the player. This notification can be performed by the CPU 121 of the effect control board 102 displaying a predetermined image on the liquid crystal display 4 based on a winning status notification command sent from the game control board 101 at the start of the game. During this time, the RT in which the replay winning probability is higher than in the normal gaming state (this is different from the RT in the above-described embodiment, and may be an RT in which there is not much difference in the replay winning probability compared to the normal gaming state). ) May be controlled together. In this case, the AT can be determined by the CPU 121 depending on whether or not the gaming state command indicating the gaming state of each game indicates such an RT.

  The winning combination to be notified by the AT controlled after the bonus winning can be constituted by a plurality of exclusive operation procedures of the stop buttons 12L, 12C, 12R for winning ( For example, "Red 7", "White 7", and "BAR" are arranged one by one at intervals of 7 frames for the middle and right reels 3C and 3R, and "Bell-Red 7-Red 7" is the target role A, Target role B for "bell-red 7-white 7", target role C for "bell-red 7-BAR", target role D for "bell-white 7-red 7", "bell-white 7-white 7" Target role E, “Bell-White 7-BAR” as target role F, “Bell-BAR-red 7” as target role G, “Bell-BAR-white 7” as target role H, “Bell-BAR-BAR”. Is the target role I).

  Here, when any type of target combination is won, if the winning combination is calculated as a winning combination, the payout rate of the medal exceeds 1, but the ratio according to the type of the target combination ( For example, assuming that there is the above-mentioned target combinations A to I and the winning probability of each is the same, if it is calculated that the prize can be won only in 1/9), the payout rate of the medal is less than 1 so that You can set the winning probability.

  In this way, between the game until the challenge bonus (1) or the challenge bonus (2) is won and the game until the required number of games is exhausted after the challenge bonus (1) or the challenge bonus (2) is won. The difference in the degree of advantage for the player is caused to be equal to or greater than the difference in the winning probability of each role in each game state, and the game can be sharpened. In addition, the AT after winning the challenge bonus (1) or the challenge bonus (2) is a game state that is truly advantageous to the player on the premise of the player's technical intervention. Can be improved.

  In the above embodiment, the door opening sensor 95 detects that the front door is in the open state, and a door opening signal of the security signal is output from the external output board 105 based on the detection signal. Had become something. However, the door opening sensor 95 may detect that the key for opening the front door has been released. In this case, even if the front door is not actually opened, If the key is released, that is, if the door opening sensor 95 detects that the front door is openable, the door output signal of the security signals is output from the external output board 105. Can be.

  Further, the detection signal of the door opening sensor 95 is input to the game control board 101, and when the door opening sensor 95 detects that the front door is open, the CPU 111 of the game control board 101 A predetermined command indicating that effect may be transmitted to the effect control board 102. Upon receiving the predetermined command, the CPU 121 of the effect control board 102 determines that the front door is open, for example, displays a predetermined message on the liquid crystal display 4 or reproduces the door opening sound to reproduce the speaker 7L, Output may be made from 7R and 7U. It is preferable that the volume level for outputting the door opening sound be the maximum level.

  Inside the slot machine 1, there are arranged a board on which a control circuit for performing various controls is mounted, a setting switch 91 for changing a set value, and the like. Must be open. However, these operations are operations that cannot be performed by the player, and the fact that the front door of the slot machine 1 is opened by a person other than the clerk of the game store means that a fraud is performed by the player. Is very likely to be By notifying the opening of the front door by displaying a message on the liquid crystal display 4 or outputting a door opening sound, the clerk of the game store can easily detect that the wrongdoing is taking place. Become.

  In the above embodiment, the security signal among the signals output from the external output board 105 is a door open signal, a set value change signal, a closing error signal, a payout error signal, another error signal, and a signal during settlement. It was a serial signal output from the same output terminal in a time-sharing manner. However, it is not necessary that all of these signals are output in a time division manner from the same output terminal as a serial format, and any two or more of these signals are output from the same output terminal in a time division manner. Things. Further, the plurality of types of signals need not be output in a serial format. In other words, when one of the following events occurs: opening of the front door by the door opening sensor 95, change of set value, occurrence of various errors including insertion error and payout error, or settlement of medals, it is possible to distinguish which event. It may be a signal that is turned on without performing the operation.

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

  On the other hand, regardless of whether the set value has been changed, that is, regardless of whether the slot machine 1 has been started with the setting key switch 92 turned ON, when the slot machine 1 is started, the stepping motor The value of the counter for counting the number may be initialized so that each excitation phase of the stepping motor is always excited in the initial pattern. In this case, regardless of whether or not the set value has been changed, the reels 3L, 3C, and 3R behave in the same manner immediately after startup, so that the player is informed that the set value has been changed. That can be prevented.

  In the above embodiment, the CPU 121 of the effect control board 102 performs the effect processing in accordance with the command sent from the game control board 101. However, the command sent from the game control board 101 is stored in the first-in first-out type command receiving buffer, and it is assumed that the commands sequentially stored in the command receiving buffer do not drop. Further, a signal corresponding to the operation of the player was not directly output to the CPU 121 of the effect control board 102.

  On the other hand, on the front surface of the liquid crystal display 4 controlled by the CPU 121 of the effect control board 102, a touch panel capable of detecting a position touched by a player as effect operation means is arranged. A signal corresponding to the position may be output to the CPU 121 of the effect control board 102. Then, in addition to the command received from the game control board 101, the CPU 121 can perform an effect process in accordance with a signal corresponding to a touch position detected by the touch panel.

  In addition, the effect control board 102 can be connected to a command simulator (test game control board) in place of the normal game control board 102 before shipment from the factory, and input from the command simulator. Based on various inspection commands, it is possible to perform an inspection of each effect means connected to the effect control board 102 or an effect operation means such as a touch panel.

  Here, when the CPU 121 receives the inspection command for inspecting the operation of the touch panel, for example, the entire touch panel is enabled, and a message “Touch the screen” is displayed on the liquid crystal display 4 on the rear side, and the message is displayed normally. It can be checked whether a touch operation is detected. In this case, until a touch operation on the touch panel is detected, the CPU 121 can prohibit command reception interrupt processing and prohibit reception of a new command.

  As described above, when the inspection command for inspecting the operation of the touch panel is received and the operation of the touch panel is performed in response to the inspection command, the command reception interrupt processing is prohibited until the detection of the touch operation, and the reception of a new command is prohibited. Therefore, even if a new command is received between the reception of the inspection command and the detection of the touch operation, processing based on the new command is not performed. For this reason, even if the inspection command is erroneously transmitted without waiting for the completion of the operation check of the touch panel, the operation check of the touch panel can be normally performed. Note that the same can be applied to a case where an effect operation means other than the touch panel, for example, a button or a dial is applied as the effect operation means.

  In the above-described embodiment, in any game state, the game can be started only by setting the bet amount to 3. However, the number of bets that can be set to start the game can be any number within the range of 1 to 3. The number of bets that can be set for each gaming state may be different. Here, when 1 or 2 is set as the number of bets in the normal gaming state, the winning probability of the small role in the internal lottery is lower than when 3 is set as the number of bets, and the small role is won. The number of payout medals can be increased.

  In the above embodiment, the stop control table is selected in advance based on the setting status of the winning flag, and when the reels 3L, 3C, 3R are stopped, the stop position of the symbol is determined with reference to the stop control table, and the stop position is determined. The slot machine in which the rotation of the reels 3L, 3C, and 3R is stopped in the table system in which the reels are stopped at the positions has been described as an example. On the other hand, based on the current symbol position and the setting status of the winning flag when the stop condition is satisfied, the pull-in control is performed so that the symbols of the winning combination are aligned, or the symbol of the winning combination is not performed. 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 that performs a removal control so that the reels are not aligned.

  In the control method, when the operation of the stop buttons 12L, 12C, and 12R is detected, the corresponding reels 3L, 3C, and 3R are displayed for 190 milliseconds from the symbol displayed at that time (the left reel 3L during the challenge bonus). Within the range of the maximum stop delay time of 75 milliseconds (a total of 5 frames including the displayed symbols and the drawn-in amount (a total of 2 frames for the left reel 3L during the challenge bonus)) It is determined whether there is a symbol of a winning combination for which a winning flag is set.

  If there is a symbol with a winning flag set (in the case of a double winning, judging from the symbol of the winning is given priority), a symbol for winning the role is selected and a winning line (already stopped. When there is a reel that is present, it is led out on a winning line (a configurable pay line) together with the symbols on the stopped reel. Otherwise, a symbol to prevent any of the winnings from winning 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 maximum stop delay time after the operation of the stop buttons 12L, 12C, 12R is detected. The display mode according to the setting status of the winning flag is derived as a display result of the variable display device 2.

  In the above embodiment, the variable display device 2 includes three reels 3L, 3C, and 3R in which a plurality of symbols are arranged in a predetermined order on an outer peripheral portion, and the symbols are rotated by driving these reels 3L, 3C, and 3R. Is 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, a slot machine using medals as a game medium used for setting the number of bets and providing a game value in accordance with a winning has been described as an example. However, a slot machine embodying the present invention may be a slot machine (so-called parrot) in which a game ball used in a pachinko game machine is applied as a game medium. When game balls are used as game media, for example, one medal can correspond to five game balls.

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

When the player operates the settlement button in the parrot, if the bet amount is already set (except when the bet amount is automatically set after winning the replay), the bet amount is set according to the set bet amount. Game balls are discharged to the lower plate provided at the lower part of the slot machine. If the bet amount is not set (including the case where the bet amount is settled first), the game balls stored in the storage plate are discharged to the lower plate through a predetermined route. The lower plate is provided with a hole through which a player operates a predetermined lever to allow the stored game balls to pass through the lower portion, and a game ball box (a so-called dollar box) is placed under the lower plate by a lever. If operated, the game balls owned by the player can be easily transferred to the game ball box.
In addition, the slot machine generally includes a variable display device having a plurality of (usually three) reels on which a plurality of types of symbols as identification information are drawn on an outer peripheral portion. The rotation is started by operating the lever, and the player operates the stop button provided corresponding to each reel to rotate within a predetermined maximum delay time from the operation timing. Stop. Then, a prize is generated according to the display mode derived when the rotation of all the reels is stopped.
In order for the winning combination of each role determined for each slot machine to occur, generally, the internal lottery performed in advance (usually when the start lever is operated) must be won and the winning flag must be set. . However, some slot machines reduce the maximum delay time from the operation timing of the stop button to the stop of at least one reel, and only pay out medals when the winning flag of any combination is not set. Some games have a gaming state called CT (Challenge Time) (or Challenge Bonus) that enables small prizes to be won.
Here, in order to improve the playability in CT, a slot machine that changes the difficulty level at the time of a player's technical intervention in CT and changes the number of medals that can be obtained by the player according to the difficulty level Has been proposed (for example, refer to JP-A-2004-33258). Further, there has been proposed a slot machine that changes the maximum stop delay time on a reel (control reel) for performing a pull-in control of a symbol stop position, even during CT, according to a medal acquisition situation of a player (for example, And JP-A-2002-17962).
However, in the slot machines disclosed in JP-A-2004-33258 and JP-A-2002-17962, CT is terminated on condition that the number of medals obtained (net increase) reaches a preset upper limit. I was supposed to. On the other hand, if the CT is to be terminated on condition that the number of medals paid out reaches a preset upper limit number, particularly if the player has a high skill, a small hand with a large number of medals paid out is played. It is advantageous to play the game with aim. For this reason, the selection of the type of the small role aiming for a prize in CT is limited, and there is a problem that the game is monotonous.
Further, in the slot machines disclosed in JP-A-2004-33258 and JP-A-2002-17962, no matter how the player plays a game while in the CT gaming state, the gaming state is controlled differently. Did not occur. In some CTs, a regular bonus lottery is performed, but this is only a problem due to the control inside the slot machine, and the player does not intervene at all. The CT in the slot machines disclosed in JP-A-2004-33258 and JP-A-2002-17962 has no game strategy other than simply performing a reel stop operation aiming at a role with a large payout number of medals. It was a monotonous game with poor strategy.
In the slot machine of the present embodiment, the player technically intervenes in the control to the specific game state controlled on condition that the derivation of the special display result is permitted in the special game state, Thereby, the interest of the game can be improved.
