The sub control means 400 updates game information when the specific command is received from the main control means 300, and gives a privilege when the game information meets a condition to give the privilege. In this constitution, the sub control means 400 comprises monitoring means for monitoring a time interval in which the specific command is received.

Description

  The present invention relates to a gaming machine such as a pachislot machine.

  Conventionally, a gaming machine having a plurality of types of control means including a main control means and a sub control means has been proposed. In the gaming machine described above, there has been a problem of an illegal act of connecting an unauthorized board to the sub-control means instead of the main control means and transmitting an unauthorized command from the unauthorized board to the sub-control means. In order to suppress the fraud, for example, Patent Document 1 discloses a technique in which a member that is destroyed when the connection between the sub control unit and the main control unit is released is provided in the case of the sub control unit. In the technique of Patent Document 1, since it is necessary to destroy the case member in order to connect the unauthorized substrate to the sub-control means, the presence or absence of fraud (injustice) The presence or absence of the possibility of having been carried out) can be confirmed.

JP 2006-239218 A

  However, in the technique of Patent Document 1, since the case of the sub-control means is housed inside the gaming machine, it is difficult to constantly monitor whether or not the case member has been destroyed. Therefore, there has been a problem that discovery of fraud is delayed. In view of the above circumstances, an object of the present invention is to detect fraudulent acts due to fraudulent commands at an early stage.

  By the way, the time interval at which an illegal command is transmitted from the illegal board described above tends to be different from each command (regular command) transmitted when a game is played in a normal procedure. Therefore, in order to solve the above-described problems, the gaming machine according to the present invention updates the game information when receiving a specific command, and main control means for transmitting the specific command in accordance with the player's operation. A sub-control means comprising: an updating means; a privilege granting means for granting a privilege when the game information satisfies a privilege granting condition; and a monitoring means for monitoring a time interval at which a specific command is received. According to the configuration of the present invention, since the time interval at which a specific command is received is monitored, it is possible to detect an illegal command based on the above-described tendency, for example. Therefore, an illegal act can be detected when an illegal command is received.

  In a preferred aspect of the present invention, the monitoring means monitors whether or not the time interval at which a specific command is received matches a predetermined illegal pattern. According to the above configuration, it is possible to detect, as an illegal command, a command whose received time interval matches an illegal pattern among the commands received by the sub-control means.

  The time interval (illegal pattern) at which an illegal command from an illegal board is received tends to be shorter than a regular command transmitted when a game is played in a normal procedure. Therefore, in a preferred aspect of the present invention, the monitoring means monitors whether the time interval at which the specific command is received is shorter than a predetermined time length. According to the above configuration, since it is monitored whether or not the interval of each command received by the sub-control means is shorter than a predetermined time length, for example, the time interval at which an illegal command is received is compared with a regular command. And an illegal command can be detected based on the tendency of being short.

  In a preferred aspect of the present invention, the main control means transmits a specific command for each game, and the privilege granting means updates the game information to a content indicating that the number of games satisfying the privilege granting condition has been executed. When it is done, a privilege is granted. In the above configuration, for example, an illegal act of obtaining a privilege by causing the sub-control unit to receive the same number of illegal commands as the number of games satisfying the privilege granting condition is assumed. According to the configuration of the present invention, since the time interval at which each fraud command is received is monitored, for example, the fraudulent act described above can be detected.

  In a preferred aspect of the present invention, the main control means executes a lottery process for each game and transmits a specific command indicating the result of the lottery process, and the privilege granting means determines the result of the lottery process in consecutive games. A privilege is given according to the history. In the above configuration, for example, an illegal act of obtaining a privilege by allowing the sub-control means to continuously receive an illegal command indicating the result of the lottery process is assumed. According to the configuration of the present invention, since the reception interval of each illegal command received continuously is monitored, for example, the illegal act described above can be detected.

  According to the present invention, fraudulent acts caused by fraudulent substrates are suppressed.

FIG. 1 is a diagram illustrating an example of a front view of the gaming machine 1. A player plays a game with the gaming machine 1 using a game medium (for example, a medal or a game ball). In the present embodiment, a gaming machine 1 (pachislot machine) in which medals are used as gaming media is illustrated.

  The gaming machine 1 includes a box-shaped cabinet 2 having an opening on the front side (player side) and a front door 3. FIG. 2 is a diagram illustrating an example of the internal structure of the cabinet 2. As shown in FIG. 2, the cabinet 2 is provided with a hinge mechanism 2a. The front door 3 is pivotally supported by the hinge mechanism 2a so that the opening of the cabinet 2 can be opened and closed. FIG. 3 is a diagram illustrating an example of a front view of the rear surface of the front door 3 (the surface on the inner side of the gaming machine 1).

  Side lamps 5 (5a, 5b) are provided on each of the left and right ends of the front face of the front door 3. Each side lamp 5 includes, for example, a light emitter such as a light emitting diode and a light-transmitting lens that covers the light emitter. The side lamp 5 emits light in a manner corresponding to each effect in the gaming machine 1.

  As shown in FIG. 1, the front door 3 is provided with a waist panel 6. On the waist panel 6, the name of the gaming machine 1 is drawn. Inside the gaming machine 1, a light emitter that irradiates the waist panel 6 is provided. For example, a light emitting diode or a cold cathode tube is adopted as the light emitter that irradiates the waist panel 6. In addition, a tray unit 7 for storing medals is provided below the waist panel 6. The tray unit 7 is formed in a shape that allows the player to freely take out the stored medals.

  The front door 3 is provided with a medal insertion portion 8 having an opening for inserting medals and a medal payout opening 9 for discharging medals from the inside of the gaming machine 1. When a prescribed number (for example, three) of medals is inserted from the medal insertion unit 8, one game can be started. The prescribed number is set according to the state of the game. The medals discharged from the medal payout opening 9 are stored in the tray unit 7.

  A panel 10 is provided on the front center side of the front door 3. A substantially rectangular display window 11 is formed in the center of the panel 10. From the display window 11, a plurality of reels 12 (12L, 12C, 12R) provided inside the cabinet 2 can be visually recognized.

  Each reel 12 includes a substantially cylindrical drum portion and a belt-like sheet member attached to the outer peripheral surface of the drum portion. The sheet member of the reel 12 is light transmissive, and a plurality of types of symbols are drawn in a row. The reels 12 are rotatably provided and are arranged in the horizontal direction so as to be adjacent to each other as shown in FIG. Specifically, the reels 12 are arranged so that the rotation axes are positioned on substantially the same straight line. Each reel 12 is fixed to a reel support 12F. The plurality of reels 12 are rotated by stepping motors 101 (101L, 101C, 101R) provided individually.

  FIG. 4 is a diagram showing the symbols arranged on each reel 12 of the present embodiment. As shown in FIG. 4, the outer periphery of each of the plurality of reels 12 is divided into 21 unit areas U (so-called “frames”). As shown in FIG. 4, one symbol is drawn in each unit region U. As shown in FIG. 4, a plurality of types of symbols including a symbol “bell” and a symbol “Replay 1” are drawn on each reel 12.

  Three symbols for each reel 12 are stopped and displayed on the display window 11 of the front door 3 shown in FIG. That is, in the state where the three reels 12 are stopped, a total of nine symbols are stopped and displayed on the display window 11. Each symbol of the reel 12 can be generally identified by the player even when the reel 12 is rotating. Therefore, the player can perform an operation to stop the reel 12 (a so-called eye-opening) at a timing when a specific symbol passes through the display window 11.

  When the medal insertion unit 8 inserts a prescribed number of medals, an effective line is set. FIG. 5 is a conceptual diagram of an effective line. The effective line is one unit area U of any one of the unit areas U of the reel 12L and one unit area U of the reel 12C and one unit of the reel 12R among the unit areas stopped and displayed in the display window 11. This is a region connecting the region U. The effective line of the present embodiment is a line that connects the unit regions U (UL2, UC2, UR2) in the middle stage of each reel 12 among the unit regions U that are stopped and displayed in the display window 11.

  A combination of symbols as a result of the game is stopped and displayed on the active line. When a predetermined symbol combination is stopped and displayed on the active line, a profit is given to the player in accordance with the stopped symbol combination. For example, when a combination of symbols related to winning is stopped and displayed on the active line, a medal is awarded to the player. Further, when a combination of symbols relating to replay is stopped and displayed on the active line, the player is given the right to replay. Specifically, when a combination of symbols related to re-game is displayed in the current game, the next game can be started even if no medal is inserted. The combination of symbols that can be stopped and displayed on the active line is determined for each game in accordance with the result of an internal lottery process to be described later.

  In the present embodiment, a line connecting the upper unit area UL1 of the reel 12L, the upper unit area UC1 of the reel 12C, and the upper unit area UR1 of the reel 12R may be referred to as an “upper line”. Similarly, a line (effective line in this embodiment) connecting the middle unit area UL2 of the reel 12L, the middle unit area UC2 of the reel 12C, and the middle unit area UR2 of the reel 12R is referred to as a “middle line”. There is a case. In addition, a line connecting the lower unit area UL3 of the reel 12L, the lower unit area UC3 of the reel 12C, and the lower unit area UR3 of the reel 12R may be referred to as a “lower line”. A line connecting the lower unit area UL3 of the reel 12L, the middle unit area UC2 of the reel 12C, and the upper unit area UR1 of the reel 12R may be referred to as an “upper right line”. Similarly, a line connecting the upper unit area UL1 of the reel 12L, the middle unit area UC2 of the reel 12C, and the lower unit area UR3 of the reel 12R may be referred to as a “right downward line”.

  As shown in FIG. 1, the panel 10 includes a loading indicator lamp 13, a BET lamp 14 (14 a, 14 b, 14 c), a start lamp 15, a payout number display 16, a stored number display 17, and a replay display lamp 18. A plurality of indicators (hereinafter referred to as “main indicator ML”) including a weight lamp 19 and a stop lamp 20 are provided.

  The insertable display lamp 13 notifies whether or not a medal from the medal insertion unit 8 can be received. Specifically, in a state where a medal from the medal insertion unit 8 can be received, the insertion possible display lamp 13 is lit. On the other hand, in a state where medals cannot be accepted, the insertion possible display lamp 13 is turned off. For example, during the period in which the reel 12 is rotating, the medal cannot be received, and therefore the insertable display lamp 13 is turned off. On the other hand, when all the reels 12 are stopped and a medal can be accepted, the thrown-in indicator lamp is lit.

  The BET lamp 14 displays the number of betting medals. The BET lamp 14 includes a single lamp 14a, a double lamp 14b, and a triple lamp 14c. When one betting medal is set, one lamp 14a is turned on. When two betting medals are set, one lamp 14a and two lamps 14b are turned on, and three betting medals are set. And the single lamp 14a, the double lamp 14b, and the triple lamp 14c are turned on.

  The start lamp 15 notifies whether or not a game start operation (operation of a start lever 24 described later) can be accepted. Specifically, the start lamp 15 is turned on when a predetermined number of betting medals are set or when a combination of symbols relating to replay is stopped on the active line.

  The payout number display 16 displays the number of medals awarded to the player when the winning symbol combination is displayed on the active line. For example, when the symbol combination “bell-bell-bell” is stopped and displayed on the active line, eight medals are awarded to the player, and the payout number display 16 displays a numerical value “8”.

  The number of medals awarded to the player can be electrically stored (stored) in the gaming machine 1 (main RAM 303 described later) (hereinafter, the number of medals stored is referred to as “credit number”). The number of credits is added when a medal is awarded as a result of the game. The credit amount is added when a medal is inserted from the medal insertion unit 8 in a state where a prescribed number of betting medals are inserted. However, there is an upper limit (50 cards) for the number of credits.

  The stored number display 17 displays the number of credits. Specifically, the stored number display unit 17 variably displays a numerical value “0” to a numerical value “50” according to the stored credit number.

  The replay display lamp 18 notifies that replay is in progress. Specifically, the re-game display lamp 18 is lit until the next game ends after the combination of symbols related to the re-game is stopped and displayed on the active line in the current game. When the re-game display lamp 18 is lit, the player is notified that the next game start operation can be performed without using a medal.

  The weight lamp 19 is lit during a wait period from when a game start operation (operation of a start lever 24 described later) is started until rotation of each reel 12 is started. The wait period is provided in order to make an average time length required for one game more than a predetermined time length (about 4.1 seconds). The stop lamp 20 notifies that the game is in a stop state that is impossible.

  As shown in FIG. 1, the front door 3 has a 1 BET button 21, a MAX-BET button 22, a checkout button 23, a start lever 24, a plurality of stop buttons 25 (25L, 25C, 25R), an effect button 26, and direction designation. A plurality of operation units including buttons 27 are provided. Each operation unit is operated by a player.

  The 1BET button 21 is operated when setting one betting medal using the stored medals. For example, when the 1BET button 21 is operated in a state where no betting medal is set, a numerical value “1” is subtracted from the number of credits to set one betting medal. That is, the player can set one betting medal using the stored medal by operating the 1BET button 21.

  The MAX-BET button 22 is operated when setting a specified number of betting medals using the stored medals. For example, when the MAX-BET button 22 is operated in a state where no betting medal is set, three (specified number) are subtracted from the number of credits, and three betting medals are set.

    The settlement button 23 is operated when a medal stored as the number of credits and a betting medal are settled. When the checkout button 23 is operated, the total number of medals including the number of credits and the betting medals is paid out from the medal payout opening 9. Note that the betting medal may be settled by the first operation of the settlement button 23 and the credit amount may be settled by the second operation.

  The start lever 24 is operated by the player when the game is started. The player can instruct the start of the game by performing a start operation on the start lever 24 in a state where the game can be started. The start lever 24 of the present embodiment can tilt in any direction of 360 degrees from a state substantially perpendicular to the front door 3. Further, the handle part of the start lever 24 is formed of a resin having translucency, and a lever effect lamp 42 is incorporated therein. The lever effect lamp 42 is lit and blinks in a predetermined effect.

  The stop button 25 is operated by the player when stopping the rotating reel 12. The stop button 25 includes a stop button 25L, a stop button 25C, and a stop button 25R. The stop button 25L corresponds to the reel 12L, the stop button 25C corresponds to the reel 12C, and the stop button 25R corresponds to the reel 12R. When the stop button 25 corresponding to the reel 12 is operated (hereinafter referred to as “stop operation”) during the period in which the reel 12 is rotating, the reel 12 stops.

  Hereinafter, in this embodiment, the first stop operation in each game is referred to as a first stop operation. Similarly, the second stop operation is referred to as a second stop operation, and the third stop operation is referred to as a third stop operation. Control in which the gaming machine 1 (main CPU 301 described later) stops the reel 12 based on the first stop operation is referred to as first stop control. Similarly, stop control of the reel 12 based on the second stop operation is referred to as second stop control, and stop control of the reel 12 based on the third stop operation is referred to as third stop control. Further, the frame (unit region U) of the reel 12 positioned at the middle line of the display window 11 at the time when the stop operation is performed is referred to as a stop operation position.

  When all the reels 12 are stopped, the combination of symbols as a result of the game is displayed on the active line, and the game ends. As will be described later, when the game is started, each reel 12 is accelerated to a certain rotational speed. During a period in which each reel 12 has a constant rotation speed (a period in which the reel 12 is constantly rotating), a stop operation for stopping and displaying the game result on the active line becomes possible. On the other hand, in the acceleration period from the start of rotation of each reel 12 to the steady rotation, even if the reel 12 is rotating, a stop operation for displaying a game result is not accepted.

  The effect button 26 is operated by the player when giving an instruction regarding the effect. For example, the user can instruct execution of a specific effect by operating the effect button 26. That is, the specific effect is executed when the effect button 26 is operated (trigger). Note that the MAX-BET button 22 can also have the function of the effect button 26. According to the above configuration, the effect button 26 is omitted, and the number of parts can be reduced.

  The direction designation button 27 is operated by the player when a menu screen is displayed on the liquid crystal display device 30, for example. The direction designation button 27 includes an upper button, a lower button, a right button, and a left button. For example, by operating the direction designation button 27, the cursor for designating an option displayed on the menu screen can be moved. Specifically, when the up button is operated, the cursor in the menu screen moves upward. Similarly, when the lower button is operated, the cursor moves downward, when the right button is operated, the cursor moves rightward, and when the left button is operated, the cursor moves leftward.

  As shown in FIG. 1, the panel 10 of the front door 3 includes a plurality of effect lamps 28 (28a to 28j) and a plurality of stop operation sequence display lamps 29 (29L, 29C, 29R). Among the plurality of effect lamps 28, effect lamp 28a to effect lamp 28e are provided on the left side of display window 11 in front view, and effect lamp 28j from effect lamp 28f to display window 11 in front view. It is provided on the right side. Each effect lamp 28 notifies the current effect state (for example, ART state) and the like.

  Each stop operation order display lamp 29 is provided in an area below the display window 11 in the panel 10 and notifies the player of the operation order (operation mode) of each stop button 25. Specifically, the stop operation order display lamp 29L is provided at a position corresponding to the reel 12L (lower left side of the display window 11), and the stop operation order display lamp 29C is set at a position corresponding to the reel 12C (the display window 11 of the display window 11). The stop operation order display lamp 29R is provided at a position corresponding to the reel 12R (lower right side of the display window 11). For example, it is assumed that the stop button 25R is notified by the first stop operation, the stop button 25C by the second stop operation, and the order of the stop button 25L by the third stop operation (so-called reverse pressing) is notified to the player. In the above case, the stop operation order display lamp 29R is lit when the game is started, the stop operation order display lamp 29C is lit after the stop button 25R is operated, and the stop operation order is displayed after the stop button 25C is operated. The display lamp 29L is lit.

  As shown in FIG. 1, a liquid crystal display device 30 that displays various images is provided above the display window 11 of the front door 3. The liquid crystal display device 30 displays a moving image and a still image according to an effect executed on the gaming machine 1.

  As shown in FIG. 3, a payout medal guide member 524 is provided on the back surface of the front door 3. The payout medal guide member 524 guides the medal from the hopper 520 to the medal payout exit 9. Specifically, the payout medal guide member 524 has an opening, and the opening faces the discharge slit 521b of the hopper 520 in a state where the front door 3 is closed. The medals discharged from the discharge slit 521b enter the opening of the payout medal guide member 524 and are guided to the medal payout exit 9 by the payout medal guide member 524.

  As shown in FIG. 2, an auxiliary storage portion 530 is provided inside the cabinet 2. The auxiliary storage unit 530 stores medals overflowing from the hopper 520. In addition, it is good also as a structure which provides the hole which penetrates the bottom part of the auxiliary storage part 530, and the bottom part of the cabinet 2, and discharges the medal overflowed from the hopper to the exterior of the gaming machine 1 through the hole.

  As shown in FIG. 2, a main control board 300 is provided inside the cabinet 2. Specifically, the main control board 300 is housed in a transparent board case and attached to the back plate of the cabinet 2. Various electronic components including a later-described main CPU 301 are mounted on the main control board 300. The main control board 300 is electrically connected to various boards including a reel board 100, a relay board 200, a sub-control board 400, and a power board 500, which will be described later, via connectors. Note that the various substrates described above may be formed of a single substrate or a plurality of substrates.

  As shown in FIG. 2, a setting display unit 36 and a setting change button 37 are formed inside the cabinet 2. The setting display unit 36 displays a setting value set in the gaming machine 1. The set value is a numerical value related to the payout rate of the gaming machine 1, and various lotteries are executed with a probability corresponding to the set value in each game. For example, setting values “1” to “6” are provided, and when the setting value “6” is set, the payout rate is the highest. In the present embodiment, when a setting change key (not shown) is inserted into a key hole (not shown) for setting change and rotated, the setting display unit 36 displays a numerical value corresponding to the setting value.

  The setting change button 37 is operated when changing the numerical value of the setting display unit 36. For example, when the setting change button 37 is operated in a state where the numerical value “1” is displayed on the setting display unit 36, the numerical value “2” is displayed on the setting display unit 36. Thereafter, each time the setting change button 37 is operated, the setting display unit 36 adds and displays numerical values one by one. However, when the setting change button 37 is operated while the numerical value “6” is displayed on the setting display unit 36, the numerical value “1” is displayed on the setting display unit 36. For example, when the start lever 24 is operated during the period in which the setting value is displayed on the setting display unit 36, the numerical value displayed on the setting display unit 36 at the time of the operation is set as the setting value.

  As shown in FIG. 3, a sub control board 400 is provided on the back surface of the front door 3. The sub-control board 400 includes various boards including an effect control board 410, an image control board 420, and a sound board 430.

For example, the power supply device 510 is supplied to a DC voltage of 32V used for driving a motor or a solenoid, a DC voltage of 12V supplied to the liquid crystal display device 30, and an electronic circuit board (for example, the main control board 300). A DC voltage of 5V is generated.

  As shown in FIG. 2, the power supply device 510 is provided with a power button 511 and a reset button 512. When the power button 511 is turned on, power is supplied to the gaming machine 1, and when the power button 511 is turned off, the power is shut off. The reset button 512 is operated when resetting a gaming state or the like.

  As shown in FIG. 2, a shielding plate 513 is positioned on the front side of the power button 511 and the reset button 512. The shielding plate 513 can move between a position where the power button 511 and the reset button 512 are shielded and a position where the shield button 511 is not shielded. Specifically, when the front door 3 is closed, the shielding plate 513 shields the power button 511 and the reset button 512. According to the above configuration, for example, an illegal act of inserting a wire from the outside of the gaming machine 1 into the sound emission hole of the speaker 31 and operating the power button 511 or the reset button 512 inside the gaming machine 1 is suppressed.

<Circuit machine circuit>
This is the end of the description of the structure of the gaming machine 1. Hereinafter, the function of each circuit provided in the gaming machine 1 will be described with reference to FIG. The gaming machine 1 includes a main control board 300, a sub control board 400, a reel board 100, a relay board 200, a sub control board 400, and a power supply board 500, as shown in FIG.

<Main control board>
As shown in FIG. 6, the main control board includes a main CPU 301, a main ROM 302, a main RAM 303, a random number generator 304, and an I / F (interface) circuit 305. Note that the main CPU 301, the main ROM 302, and the main RAM 303 may be provided as separate electronic devices, or may be provided as a one-chip microcomputer in which each element is integrally configured.

  The main ROM 302 stores a control program executed by the main CPU 301 and various data (for example, a winning area lottery table) in a nonvolatile manner. The main RAM 303 stores various data used in each process executed by the main CPU 301.

  The main CPU 301 reads various control programs stored in the main ROM 302 and performs predetermined processing in accordance with the progress of the game, thereby including various types including the sub control board 400, each reel 12, the hopper 520, and the main display ML. Control the equipment.

  The random number generator 304 generates a random value R1 used in an internal lottery process to be described later. The random number generator 304 of this embodiment includes a counter circuit, a sampling circuit, and a pulse generation circuit (all not shown), and generates a hardware random number. Specifically, the pulse generation circuit outputs a signal to the counter circuit at a predetermined cycle. The numerical value of the counter circuit is incremented by “1” every time a signal is input from the pulse generation circuit. The sampling circuit stores the numerical value of the counter circuit as the random number value R1 when the player starts the game. The random value R1 is generated in the range of numerical values “0” to “65535”. A software random number may be adopted as the random value R1.

  In the present embodiment, a random value R2 is generated in addition to the random value R1. The random number value R2 is a software random number acquired from a register built in the main CPU 301, and is generated in the range of numerical values “0” to “255”. As will be described later, the random value R2 is used in the spinning drum effect control process.

  The I / F circuit 305 inputs a signal from each switch SW (for example, the start switch 24SW) of each operation unit (for example, the start lever 24) and each sensor SE (for example, the medal sensor 34SE) to the main CPU 301. The signal from each switch SW and each sensor SE is a high level or low level signal. In the present embodiment, for the sake of explanation, a first level (high level or low level) signal is represented as an ON signal, and a second level (low level or high level) signal is represented as an OFF signal. To do. Whether the first level of the ON signal is high level or low level is set according to the type of the switch SW or the sensor SE.

  The I / F circuit 305 outputs various signals for driving the main display ML, the hopper 520, and each reel 12 to the outside of the main control board 300. Further, the I / F circuit 305 outputs various commands to the sub control board 400. In order to prevent an illegal command from being input to the main control board, the command from the sub control board 400 is not received by the main control board 300.

  A signal from the main control board 300 is input to the reel board 100. The reel substrate 100 outputs a drive pulse to each reel 12 in response to a signal from the main control substrate 300. Each stepping motor 101 of each reel 12 is driven in accordance with a drive pulse from the reel substrate 100.

  The stepping motor 101 includes a plurality of (four) coils. Among the coils, the excitation coil combination is sequentially switched every time a drive pulse is input from the reel substrate 100, and the reels 12 are rotated by sequentially switching the excitation coil combinations. Specifically, when the combination of the excited coils of the stepping motor 101 is switched only once, the reel 12 rotates by a predetermined angle. For example, when the pulse is applied 24 times, the reel 12 rotates by an angle corresponding to one frame (unit area U), and when the pulse is applied 504 times, the reel 12 rotates once. In the above configuration, when the time interval at which the drive pulse is applied is short, the rotation speed of the reel is faster than when the time interval is long.

  The main control board 300 receives ON / OFF signals from a plurality of reel sensors 111 (111L, 111C, 111R) via the reel board 100. Of the reel sensors 111, the reel sensor 111L corresponds to the reel 12L, the reel sensor 111C corresponds to the reel 12C, and the reel sensor 111R corresponds to the reel 12R. Each reel sensor 111 outputs an ON signal when the rotation angle of the corresponding reel 12 is the reference position. On the other hand, each reel sensor 111 outputs an OFF signal when the rotation angle of each reel 12 is other than the reference position. The main CPU 301 of the main control board 300 can determine the rotation angle of each reel 12 from the signal from each reel sensor 111 and the number of times the drive pulse is output to each stepping motor 101.

  The relay board 200 relays a signal from the main control board 300 to the main display ML. In response to the signal output from the main control board 300, the main display ML is driven. The relay board 200 relays an ON / OFF signal input to the main control board 300 from each sensor (such as a start switch 24SW described later) that detects the operation of each operation unit (such as the start lever 24).

  The 1BET switch 21SW detects an operation of the 1BET button 21 by the player. The ON signal from the 1BET switch 21SW is input to the I / F circuit 305 of the main control board 300 via the relay board 200. When the ON signal from the 1BET switch 21SW is input, the main CPU 301 adds one medal to the betting medal.

  The MAX-BET switch 22SW detects the operation of the MAX-BET button 22 by the player. The ON signal from the MAX-BET switch 22SW is input to the I / F circuit 305 of the main control board 300 through the relay board 200. When the ON signal from the MAX-BET switch 22SW is input, the main CPU 301 sets a prescribed number of medals as betting medals. Hereinafter, the 1BET switch 21SW and the MAX-BET switch 22SW may be collectively referred to as “BET switches”.

  The settlement switch 23SW detects the operation of the settlement button 23 by the player. The ON signal from the settlement switch 23SW is input to the I / F circuit 305 of the main control board 300 via the relay board 200.

  When an ON signal is input from the settlement switch 23SW or when a combination of symbols related to winning is displayed on the active line, the main CPU 301 outputs a hopper drive signal to the hopper 520. The hopper drive signal is input from the main control board 300 to the hopper 520 through the power supply board 500. The hopper 520 pays out medals when a hopper drive signal is input.

  The payout sensor 112SE inputs a payout signal to the main control board 300 every time one medal is paid out from the hopper 520. The payout signal is input to the main control board 300 via the power supply board 500. For example, a payout sensor 112SE is provided at a position where a medal passing through the discharge slit 521b of the hopper 520 is detected, and when a medal is detected, the payout sensor 112SE outputs a payout signal. The main CPU 301 can determine the number of medals paid out by counting the number of times the payout signal is input.

  Full tank sensor 530SE detects that auxiliary storage unit 530 is full. Specifically, the full tank sensor 530SE is provided at a predetermined height from the bottom of the auxiliary storage unit 530, and when the medal inside the auxiliary storage unit 530 increases and reaches the position of the full tank sensor 530SE, the ON signal Is output to the main control board 300. The ON signal of the full sensor 530SE is input to the main control board 300 through the power supply board 500. When the ON signal of the full sensor 530SE is input, the main CPU 301 displays a message “hopper full error” on the liquid crystal display device 30, for example, and shifts to an error state. When the message is displayed, for example, after an amusement shop clerk collects medals in the auxiliary storage unit 530, the error state is canceled by operating the reset button 512.

  The power switch 511SW is switched to an ON state or an OFF state by operating the power button 511. When the power switch 511SW is in the ON state, power is supplied from the power supply device 510 to the gaming machine 1, and when the power switch SW is in the OFF state, the power from the power supply device 510 to the gaming machine 1 is shut off. The power supply device 510 generates a DC voltage when power is supplied. The DC voltage generated by the power supply device 510 is supplied to various devices including the hopper 520 through the power supply substrate 500.

  The reset switch 512SW is provided in the power supply device 510, and outputs a reset signal to the main control board 300 when the reset button 512 is operated. The reset signal is input to the main control board 300 via the power supply board 500. When receiving the reset signal, the main CPU 301 cancels the error state, for example. Note that a plurality of reset switches 512SW (reset buttons 512) may be provided. For example, in addition to the reset switch 512SW provided in the power supply device 510, the lock device 4 may be provided with a reset switch. For example, when the key is inserted into the keyhole of the locking device 4 and the key is rotated to the right, the front door 3 is unlocked, and when the key is rotated to the left, a reset signal is output from the reset switch. Preferably employed.

  The setting change switch 37SW detects an operation of the setting change button 37. The ON signal from the setting change switch 37SW is input to the main control board 300. When an ON signal is input from the setting change switch 37SW, the main CPU 301 updates the display on the setting display unit 36. When an ON signal is input from the setting change switch 37SW during a period when the setting value is not displayed on the setting display unit 36, the main CPU 301 determines a predetermined value in the same manner as when a reset signal is input from the reset switch 512SW. It is good also as a structure which performs reset operation.

  The medal sensor 34SE detects medals inserted from the medal insertion unit 8. Specifically, the medal sensor 34SE outputs an ON signal when a medal is located inside the selector 34 in the medal flow path. On the other hand, the medal sensor 34SE outputs an OFF signal when no medal is located inside the selector 34. The ON / OFF signal from the medal sensor 34SE is input to the main control board 300 via the relay board 200. In addition to the medal sensor 34SE of the selector 34 described above, a medal sensor may be provided on the inserted medal guide member 522 located downstream of the selector 34. In the above configuration, when the ON signal of the medal sensor of the inserted medal guide member 522 is input after the ON signal of the medal sensor 34SE of the selector 34 is input, the main CPU 301 determines that an appropriate medal has been inserted. May be. On the other hand, for example, when the ON signal of the medal sensor of the inserted medal guide member 522 is not input after the ON signal of the medal sensor 34SE of the selector 34 is input, there is a possibility that the medal stays in the medal flow path. Therefore, the main CPU 301 may notify an error.

  ON / OFF signals from a plurality of stop switches 25SW (25SWL, 25SWC, 25SWR) are input to the main control board 300 via the relay board 200. Of the stop switches 25SW, the stop switch 25SWL corresponds to the stop button 25L, the stop switch 25SWC corresponds to the stop button 25C, and the stop switch 25SWR corresponds to the stop button 25R. The main CPU 301 performs stop control of the reel 12 corresponding to the stop switch 25SW to which the ON signal is input. Specifically, when an ON signal is input from the stop switch 25SWL, the reel 12L is controlled to stop. Similarly, the main CPU 301 performs stop control of the reel 12C when an ON signal is input from the stop switch 25SWC, and performs stop control of the reel 12R when an ON signal is input from the stop switch 25SWR.

  The start switch 24SW detects the operation of the start lever 24 by the player. The ON signal from the start switch 24SW is input to the I / F circuit 305 of the main control board 300 via the relay board 200. When the ON signal is input from the start switch 24SW, the main CPU 301 controls, for example, each stepping motor 101 to rotate each reel 12. Further, an ON signal from the setting change switch 37 </ b> SW is input to the main control board 300.

  The start switch 24SW of the present embodiment is formed so as to be able to detect the direction in which the start lever 24 is operated. Specifically, the start switch 24SW can individually detect any of push-up operation for pushing up the start lever 24, push-down operation for pushing down, right-hand operation for tilting to the right, and left-hand operation for tilting to the left as viewed from the player side. is there. For example, when the start switch 24SW is operated to the right side, the start switch 24SWU that outputs an ON signal when the start lever 24 is pushed up, the start switch 24SWd that outputs an ON signal when the start lever 24 is pushed down, and ON. The sensor includes a start switch 24SWR that outputs a signal and a start switch 24SWL that outputs an ON signal when operated to the left. According to the above configuration, for example, it is possible to vary the effect that is executed when the start lever 24 is pressed and when the start lever 24 is pressed.

<Sub control board>

As shown in FIG. 6, the sub control board 400 includes a plurality of boards including an effect control board 410, an image control board 420, and a sound board 430. The sub-control board 400 includes various sensors including an effect button switch 26SW and a direction specifying switch 27SW, a side lamp 5, an effect lamp 28, a stop operation order display lamp 29, and a lever effect lamp 42. Various lamps are electrically connected.

  As shown in FIG. 6, the effect control board 410 includes an I / F circuit 411, a sub CPU 412, a sub ROM 413, and a sub RAM 414. The effect control board 410 (sub CPU 412) controls various lamps including the side lamp 5, the effect lamp 28, the stop operation order display lamp 29, and the lever effect lamp 42, and the sound board 430. In addition, the effect control board 410 gives a command for displaying an image on the liquid crystal display device 30 to the image control board 420.

  The sub ROM 413 stores a control program executed by the sub CPU 412 and various data. For example, an effect lottery table for determining the type of effect and lamp data indicating flashing patterns of various lamps are stored in the sub ROM 413.

  The sub RAM 414 functions as a work area for storing various data in a volatile (temporary) manner. The I / F circuit 411 receives a command from the main control board 300 (I / F circuit 305). The command received by the I / F circuit 411 is supplied to the sub CPU 412. The command received by the I / F circuit 411 includes, for example, a display winning combination command indicating the type of winning combination stopped on the active line.

  The sub CPU 412 executes a control program stored in the sub ROM 413 and controls various lamps (for example, the side lamp 5) and the sound board 430 based on each data stored in the sub ROM 413. For example, the sub CPU 412 reads data indicating the blinking pattern of the side lamp 5 from the sub ROM 413 and blinks the side lamp 5. Further, the sub CPU 412 uses a random value R3 used in an effect lottery process described later, a random value R4 used in an ART lottery process, a random value R5 used in a mode transition lottery process, and a random value 6 used in a special zone lottery process. And the random value R7 used in the extra lottery process is generated. As the random value R3 to the random value R7, for example, a software random number in the range of 0 to 32767 is preferably employed. Note that the sub ROM 413 may be composed of a single electronic component or a plurality of electronic components (storage devices).

  The image control board 420 displays various images on the liquid crystal display device 30 in accordance with commands from the effect control board 410. As shown in FIG. 6, the image control board 420 includes a liquid crystal control CPU 421, a liquid crystal control ROM 422, a VDP (Video Display Processor) 423, a CGROM 424, and a VRAM 425.

  The liquid crystal control CPU 421 executes a control program stored in the liquid crystal control ROM 422, and gives an instruction according to a command from the effect control board 410 to the VDP 423. The CGROM 424 stores compressed and encoded image data (for example, texture data). The VDP 423 includes an image decoder and a drawing circuit (both not shown). When an instruction from the liquid crystal control CPU 421 is input to the VDP 423, the image decoder reads image data from the CGROM 424 in response to the instruction. The image decoder decompresses (decodes) the read image data and stores it in the VRAM 425. The drawing circuit displays various images on the liquid crystal display device 30 in accordance with the image data stored in the VRAM 425.

  The sound board 430 is controlled by the sub CPU 412 to generate an acoustic signal.

Each piece of acoustic data is data indicating, for example, each piece of music including a music piece in a specific game state, a sound output every time the player operates the stop button 25, and an error sound output in an error state.

  The sound source IC 431 generates an acoustic signal from the acoustic data in the sound source ROM 432. The sound source IC 431 includes a decoder, a control register, and an A / D converter (all not shown). The decoder of the sound source IC 431 reads sound data from the sound source ROM 432 in accordance with an instruction from the sub CPU 412. The decoder of the sound source IC 431 adjusts the volume of the read sound data and then stores the sound data in the control register. A plurality of sound data is stored in the control register, and each sound data stored in the control register is supplied to the A / D converter in the stored order. The A / D converter generates an acoustic signal from the acoustic data and supplies it to the amplifier 433.

  The amplifier 433 amplifies the acoustic signal supplied from the sound source IC 431 (A / D converter) and supplies it to the speaker 31 and the speaker 32. In the present embodiment, the sub CPU 412 controls the sound source IC 431 to generate an acoustic signal. However, for example, the liquid crystal control CPU 421 described above may control the sound source IC 431. The CPU to be controlled may be provided separately from the sub CPU 412 and the liquid crystal control CPU 421.

<Each data used by main CPU>
The description of each circuit of the gaming machine 1 is as described above. Hereinafter, various data stored in the main ROM 302 will be described with reference to the drawings. The main ROM 302 includes a symbol arrangement table shown in FIG. 7, a symbol code table shown in FIG. 8, a winning area lottery table shown in FIGS. 9 to 13, a winning combination determination table shown in FIG. 14, and a winning combination definition table shown in FIG. 16, various data including an RT transition table shown in FIG. 16, a spinning effect determination table shown in FIG. 19, and a spinning effect drive table shown in FIG. 20 are stored.

  FIG. 7 is a conceptual diagram of the symbol arrangement table. In the symbol arrangement table, the symbol position is associated with the symbol type at the symbol position. Each symbol position (“00” to “20”) in the symbol arrangement table corresponds to each unit area (U0 to U20) shown in FIG. 4, and each symbol in the symbol arrangement table is the reel 12 shown in FIG. Corresponds to each symbol drawn in The symbol position located in the middle line during rotation is stored in the symbol counter of the main RAM 303.

  FIG. 8 is a conceptual diagram of the symbol code table. The symbol code table is configured to include data (symbol code) specifying each symbol of each reel 12. As understood from FIG. 4 or FIG. 7, each reel 12 has “red 7”, “blue 7”, “BAR 1”, “BAR 2”, “replay 1”, “replay 2”, “bell”, “grape”, “watermelon”, and “cherry”. 10 types of symbols are arranged. As shown in FIG. 8, each symbol code corresponds to each of ten types of symbols. Specifically, “Red 7” corresponds to symbol code “00000001”, “Blue 7” corresponds to symbol code 02 “00000010”, and “BAR1” corresponds to symbol code 03 “00000011”. "BAR2" corresponds to symbol code 04 of "00000100", "Replay 1" corresponds to symbol code 05 of "00000101", and "Replay 2" corresponds to symbol code 06 of "00000110". "Bell" corresponds to symbol code 07, "00000111", "Grape" corresponds to symbol code 08, "00001000", and "Watermelon" corresponds to symbol code 09, "00000101". Correspondingly, the symbol code 10 “00001010” corresponds to “Cherry”.

  9 to 13 are conceptual diagrams of winning area lottery tables. FIG. 14 is a conceptual diagram of the winning combination determination table. The main CPU 301 determines a winning area by using a winning area lottery table and a random value R1 in an internal lottery process to be described later. In addition, the main CPU 301 uses the determined winning area and the winning combination determination table to set a combination of symbols that permits display on the active line.

  As shown in FIGS. 9 to 13, each winning area lottery table includes a plurality of winning areas and lottery values corresponding to the winning areas. 9 to 13 show the names of the winning areas. The winning area lottery table is stored in the main ROM 302 for each set value (1 to 6). The winning area lottery tables that are referred to when the set value is “1” are illustrated in FIGS. 9 to 13.

  Each winning area designates each winning combination defined in the winning combination determination table shown in FIG. For example, it is assumed that “push order bell A1” in the winning area “18” is determined by the internal lottery process. As is understood from FIG. 14, the winning area “18” designates the winning combination “middle bell”, the winning combination “upper bell 2”, and the winning combination “upper bell 5”. That is, the internal lottery process is also referred to as a process for determining a winning combination to be won in each game. The combination of symbols of the winning combination designated in the winning area is permitted to stop on the active line.

  Each lottery value in the winning area lottery table is a numerical value that is subtracted from the random value R1 in the internal lottery process. Specifically, in the internal lottery process, the main CPU 301 subtracts each lottery value corresponding to each winning area from the random value R1 in ascending order of the winning area (from “00” to “32”). In the internal lottery process, a winning area is determined when the result of subtracting the lottery value from the random value R1 becomes a negative number. The larger the lottery value, the higher the probability of becoming a negative number when subtracted from the random value R1. That is, the winning area having a larger lottery value in the winning area has a higher probability of winning.

  Of the plurality of winning area lottery tables shown in FIGS. 9 to 13, the winning area lottery table corresponding to the RT gaming state in each game is used in the internal lottery process of the game. The RT gaming state of the present embodiment includes an RT0 gaming state, an RT1 gaming state, an RT2 gaming state, an RT3 gaming state, and an RT4 gaming state. 9 is a winning area lottery table in the RT0 gaming state, FIG. 10 is a winning area lottery table in the RT1 gaming state, FIG. 11 is a winning area lottery table in the RT2 gaming state, and FIG. FIG. 13 is a winning area lottery table in gaming state, and FIG. 13 is a winning area lottery table in RT4 gaming state.

  As understood from FIGS. 9 to 13, the lottery values in the winning areas “01” to “17” (hereinafter referred to as “re-game winning area”) are different for each RT gaming state. Specifically, in the RT0 gaming state, as shown in FIG. 9, a lottery value “8979” is allocated to the “ordinary replay” winning area in the replay winning area, and the lottery values of the other replay winning areas are The numerical value is “0”. That is, in the RT0 gaming state, “normal replay” in the re-game winning area is won, and the probability that any winning area in the re-game winning area is determined is 8979/65536.

  As shown in FIG. 10, in the RT1 gaming state, a lottery value “2244” is assigned to each winning area of “RT1 push order replays 1 to 4” in the replaying winning area, and lottery values in other replaying winning areas. Is the numerical value “0”. That is, in the RT1 gaming state, “RT1 push order replays 1 to 4” of the re-game winning areas are won, and the probability that any winning area of the re-game winning areas is determined is 8976 (2244 × 4) / 65536. It is. That is, the winning probability of the re-game winning area in the RT1 gaming state is substantially equal to the winning probability 8979/65536 of the re-game winning area in the RT0 gaming state.

  As shown in FIG. 11, in the RT2 gaming state, the lottery value “5” is assigned to the “normal replay” winning area in the replay winning area, and lottery is assigned to each winning area of “RT2 push order replays 1 to 6”. The value “7069” is assigned, and the lottery value of the other re-game winning area is the numerical value “0”. In other words, in the RT2 gaming state, among the replay winning areas, “normal replay” and “RT2 push order replays 1 to 6” are won, and the probability that any one of the regame winning areas is determined is 42419 (5 + 7069). X6) / 65536.

  As shown in FIG. 12, in the RT3 gaming state, the lottery value “33443” is allocated to the “ordinary replay” winning area in the replay winning area, and the lottery is assigned to each winning area of “RT3 push order replays 1 to 4”. The value “2244” is assigned, and the lottery value in the other replay winning area is the numerical value “0”. That is, in the RT3 gaming state, the probability of the “replay winning area” “normal replay” or “RT3 push order replays 1 to 4” being won and any of the regame winning areas being determined is 46907 (33443 + 2244). X6) / 65536.

  As shown in FIG. 13, in the RT4 gaming state, a lottery value “2419” is allocated to the winning area of “normal replay”, and “7-match replay” and “special game falling replay” are selected in the replay winning area. The lottery value “20000” is assigned to the winning area, and the lottery values in the other replay winning areas are the numerical value “0”. That is, in the RT4 gaming state, “RT3 push order replays 1 to 4” of the re-game winning areas are won, and the probability that any one of the re-game winning areas is determined is 42419 (2419 + 20000 × 2) / 65536. It is.

  As understood from the above description, the winning probability of the re-game winning area from the RT2 gaming state to the RT3 gaming state is higher than that of the re-game winning area of the RT1 gaming state. Further, as understood from FIGS. 9 to 13, the lottery values in the winning areas “18” to “32” (hereinafter referred to as “winning winning area”) are common to the respective RT gaming states. That is, the winning probabilities in the winning areas “18” to “32” are the same in each RT gaming state. Therefore, the RT2 gaming state to the RT4 gaming state are RT gaming states that have a higher winning probability of winning combination and are advantageous to the player than the RT0 gaming state and the RT1 gaming state.

  FIG. 15 is a conceptual diagram of a winning combination defining table that defines combinations of symbols for each winning combination. As shown in FIG. 15, the winning combination rule table includes the permission bit number of each winning combination, the combination of symbols of each winning combination, and the number of medals to be paid out when each winning combination stops on the active line. Composed.

  For example, a game won by the winning role “middle bell” (a game in which the winning bells (A1 to A4, B1 to B4) from the winning area “18” to the winning area “25” or the common bell of the winning area “26” are won) ), A combination of symbols “bell”, “bell”, and “bell” can be displayed on the middle line as an active line (middle line). When the winning combination “upper bell 1-8” is displayed on the active line (middle line), the symbol combination “bell” “bell” “bell” is displayed on the upper line (invalid line).

  As shown in FIG. 15, the winning role “middle bell” “upper bell 1-8” “slanted watermelon” “upper watermelon” “horn cherry” “middle cherry” “weak chance” or “strong chance” (winning winning prize) When the winning combination designated by the game in which the area has been won is displayed on the active line, a payout number of medals corresponding to each winning combination is awarded to the player. In the present embodiment, a winning combination in which medals are paid out when displayed on the active line is referred to as a “winning winning combination”. Also, “7-match replay”, “RT4 transition replay”, “RT3 transition replay”, “RT2 transition replay”, “special replays A to C” or “normal replay” (winning role designated by the game where the replay winning area is won) When is displayed on the active line, the next game is set to replay. In the present embodiment, the winning combination in which the next game is set to be replayed when displayed on the active line is referred to as a regame player.

  Each permission bit number designates each display permission bit in the display permission bit storage area of the main RAM 303. The display permission bit storage area is configured to include a plurality of display permission bits, and each display permission bit corresponds to each winning combination. For example, it is assumed that the push order bell of the winning area “18” wins and the stop of the winning combination “middle bell”, “upper bell 2”, and “upper bell 5” on the active line is permitted. In the above case, as shown in FIG. 15, the display permission bits designated by the permission bit numbers “8”, “10”, and “13” in the display permission bit storage area are set to “1”, and the other bits are Set to “0”.

  The main RAM 303 stores a display combination storage area to be compared with the display permission bit storage area in the display determination process described later. The display combination storage area includes a plurality of displayable bits, and each displayable bit corresponds to each winning combination (similar to the display permission bit storage area). Each displayable bit is set to “1” when there is a possibility that the winning combination corresponding to the displayable bit stops on the active line, and there is no possibility that the corresponding winning combination stops on the active line. In this case, it is set to “0”. For example, at the time when each reel 12 starts to rotate, all winning combinations may stop at the active line, so all displayable bits are set to “1”. Each displayable bit in the display combination storing area is updated every time each reel 12 is stopped, and at the time when all the reels 12 are stopped, only the displayable bits corresponding to the winning combination actually stopped on the active line. Becomes “1”.

  As described above, the RT gaming state includes the RT1 gaming state to the RT4 gaming state. The RT gaming state transitions when the RT transition symbol is displayed on the active line. FIG. 16 is a conceptual diagram of an RT transition table in which RT transition symbols and RT gaming states are associated with each other. There are a plurality of types of RT transition symbols including an RT1 transition symbol corresponding to the RT1 gaming state, an RT2 transition symbol corresponding to the RT2 gaming state, an RT3 transition symbol corresponding to the RT3 gaming state, and an RT4 transition symbol corresponding to the RT4 gaming state. Is provided. When the RT transition symbol stops on the active line, the RT game state transitions to the RT transition symbol.

  As shown in FIG. 16, the RT2 transition symbol is RT2 transition replay. That is, the RT2 transition replay is a combination of symbols that serve both as an RT transition symbol and a re-playing combination. Similarly, the RT3 transition symbol is RT3 transition replay. The RT4 transition symbol is RT4 transition replay. On the other hand, the RT1 transition symbol is not a combination of symbols related to the winning combination. Specifically, in the game in which the push order bells (A1 to A4, B1 to B4) are won in the internal lottery process, both the winning combination “middle bell” and “upper bell 1 to 8” are displayed on the active line. If not, the RT1 transition symbol is displayed on the active line.

  The winning combination won in the internal lottery process stops on the active line according to the operation mode of each stop button 25 of the player. Specifically, each winning combination stops on the active line according to the stop operation position of each stop button 25 and the order of the stop operation. For example, a symbol located within a range of 4 frames from the stop operation position (5 frames including the stop operation position) (hereinafter referred to as “retraction range”) can be stopped on the active line, and a symbol located outside the range is Even the symbols that make up the winning combination are not stopped on the active line (so-called “missing” occurs). As described above, a plurality of types of winning combinations may be won in a single game. In a game in which a plurality of types of winning combinations are won, the winning combination that stops on the active line is selected according to the order of the stop operation.

  FIGS. 17 and 18 are explanatory diagrams of the correspondence relationship between the winning area, the stop operation order, and the winning combination (a combination of symbols stopped on the effective line) that stops on the active line when the stop operation is performed in each stop operation order. It is.

  FIG. 17 is a diagram illustrating a winning combination that stops on the active line in each stop operation order in a game in which any of the winning areas “03” to “16” is won. When the winning areas “03” to “16” are determined, various re-game players become the winning players.

  As shown in FIG. 17, in a game in which “RT3 push order replay 1” is determined as the winning area, each stop button 25 is a stop button 25C (middle), a stop button 25L (left), and a stop button 25R (right). When operated in the stop operation sequence (hereinafter simply referred to as “middle-left-right”), the winning combination “7-match replay” or “RT4 transition replay” stops on the active line. Specifically, in the game in which “RT3 push order replay 1” is determined as the winning area, the stop operation order is “middle-left-right” and “red 7” is within the pull-in range of all the reels 12. Is located, “Red 7-Red 7-Red 7” “7-match replay” stops at the active line. In the game in which “RT3 push order replay 1” is determined as the winning area, the stop operation order is “middle-left-right” and “blue 7” is located within the pull-in range of all reels 12. In this case, “7-match replay” of “blue 7-blue 7-blue 7” stops at the active line. On the other hand, when “7-match replay” cannot be pulled into the active line with any of the reels 12, “RT4 transition replay” stops. When the stop operation order is other than “middle-left-right”, “normal replay” stops at the valid line regardless of the stop operation position of each stop button 25.

  Similarly, when “RT3 push order replay 2” is determined as the winning area, if the stop operation order is “middle-right-left”, “7-match replay” or “RT4 transition replay” depends on the stop operation position. Will stop. On the other hand, if the stop operation order is other than “middle-right-left”, “normal replay” stops at the active line. When “RT3 push order replay 3” is determined as the winning area, “7-match replay” or “RT4 transition replay” is stopped depending on the stop operation position if the stop operation order is “right-middle-left”. To do. On the other hand, if the stop operation order is other than “right-middle-left”, “normal replay” stops at the active line. When “RT3 push order replay 4” is determined as the winning area, “7-match replay” or “RT4 transition replay” is stopped depending on the stop operation position if the stop operation order is “right-left-middle”. To do. On the other hand, if the stop operation order is other than “right-left-middle”, “normal replay” stops at the active line. As understood from the above description, “RT4 transition replay” or “7-match replay” does not stop on the active line as long as the stop button 25L is stopped first.

  As shown in FIG. 17, when “RT2 push order replay” is determined as the winning area, “RT3 transition replay” or “RT3 transition replay” or according to the stop operation order or “RT2 push order replay” or “Normal replay” stops at the active line. Specifically, in the game in which “RT2 push order replay 1” is determined, when the stop operation order is “left-middle-right”, “RT3 transition replay” stops at the active line. On the other hand, if the stop operation order is other than “left-middle-right”, “normal replay” stops at the active line. Similarly, in a game in which “RT2 push order replay 2” is determined, if the stop operation order is “left-right-middle”, “RT3 transition replay” stops at the active line, and the stop operation order is “left If it is other than “Right-Middle”, “Normal Replay” stops at the active line. In a game in which “RT2 push order replay 3” is determined, if the stop operation order is “middle-left-right”, “RT3 transition replay” stops at the active line, and the stop operation order is “middle-left-right”. If it is other than “right”, “normal replay” stops at the active line. In a game in which “RT2 push order replay 4” is determined, when the stop operation order is “middle-right-left”, “RT3 transition replay” stops at the active line, and the stop operation order is “middle-right- If it is other than “Left”, “Normal Replay” stops at the active line. In a game in which “RT2 push order replay 5” is determined, when the stop operation order is “right-middle-left”, “RT3 transition replay” stops at the active line, and the stop operation order is “right-middle- If it is other than “Left”, “Normal Replay” stops at the active line. In a game in which “RT2 push order replay 6” is determined, when the stop operation order is “right-left-middle”, “RT3 transition replay” stops at the active line, and the stop operation order is “right-left- If it is other than “medium”, “normal replay” stops at the active line.

  As shown in FIG. 17, in a game in which “RT1 push order replay” is determined as the winning area, “RT2 transition replay” depends on the types (1 to 4) of “RT1 push order replay” and the stop operation order. Or “Normal Replay” stops at the active line. Specifically, when “RT1 push order replay 1” is determined and the stop operation order is “middle-left-right”, “RT2 transition replay” stops at the active line, and the stop operation If the order is other than “middle-left-right”, “normal replay” stops at the active line. Similarly, in a game in which “RT1 push order replay 2” is determined, if the stop operation order is “middle-right-left”, “RT2 transition replay” stops at the active line, and the stop operation order is “middle If it is other than “Right-Left”, “Normal Replay” stops at the active line. In a game in which “RT1 push order replay 3” is determined, when the stop operation order is “right-middle-left”, “RT2 transition replay” stops at the active line, and the stop operation order is “right-middle- If it is other than “Left”, “Normal Replay” stops at the active line. In a game in which “RT1 push order replay 4” is determined, when the stop operation order is “right-left-middle”, “RT2 transition replay” stops at the active line, and the stop operation order is “right-left- If it is other than “medium”, “normal replay” stops at the active line. As understood from the above description, the “RT2 transition replay” does not stop on the active line as long as the stop button 25L is stopped first.

  FIG. 18 is a diagram illustrating a winning combination that stops on the active line in each stop operation order in a game in which any of the winning areas “18” to “25” is won. When any of the winning areas “18” to “25” is determined, either “middle bell” or “upper bells 1 to 8” is designated as a winning combination (FIG. 14). As understood from FIG. 18, one of the “middle bell” and the “upper bell” stops at the active line according to the stop operation sequence. However, as will be described later, the “upper bell” may be missed depending on the stop operation position.

  As shown in FIG. 18, in the game in which “push order bell A1” is determined as the winning area, when the first stop operation is performed on the stop button 25C, the winning combination “ The middle bell stops. On the other hand, when the first stop operation other than the stop button 25C is performed, the winning combination “upper bell 2” or “upper bell 5” stops. However, the winning combination “upper bell 2” and “upper bell 5” may be missed depending on the stop operation position. As described above, when each “upper bell” is missed, the RT1 transition symbol stops at the active line. In a game where one of “push order bell A2” to “push order bell A4” is won as the winning area, as in the game where “push order bell A1” is won, the stop button 25C is operated first. The winning combination “middle bell” stops on the active line regardless of the stop operation position. On the other hand, when a button other than the stop button 25C is first operated, various “upper bells” or RT1 transition symbols are stopped at the effective line according to the stop operation position.

  As shown in FIG. 18, in the game in which “push order bell B1” is determined as the winning area, when the first stop operation is performed on the stop button 25R, the winning combination “ The middle bell stops. On the other hand, when the first stop operation other than the stop button 25R is performed, the winning combination “upper bell 3” or “upper bell 5” stops. However, like the “upper bell 5”, the winning combination “upper bell 3” is missed depending on the stop operation position. In a game where one of “push order bell B2” to “push order bell B4” is won as the winning area, as in the game where “push order bell B1” is won, the stop button 25R is operated first. The winning combination “middle bell” stops on the active line regardless of the stop operation position. On the other hand, when a button other than the stop button 25R is first operated, various “upper bells” or RT1 transition symbols are stopped at the effective line according to the stop operation position.

  As understood from the above description, in the game in which “push order bell” (A1 to A4, B1 to B4) is determined as the winning area, the “middle bell” is set as long as the stop button 25L is stopped first. Do not stop at active line. In addition, as long as the “middle bell” is stopped in the stop operation sequence in which it is stopped on the active line, the RT1 transition symbol does not stop on the active line.

  In the present embodiment, in the game where each “push order bell” in the winning areas “18” to “25” is won, the stop operation order in which the winning combination “middle bell” stops on the active line is indicated as “push order bell” win. It is called the correct answer push order at the time. Similarly, a stop operation sequence in which “RT2 transition replay” as an RT2 transition symbol is stopped in a game in which each “RT1 push order replay” in the winning areas “13” to “16” is won, and from the winning area “07”. The stop operation sequence in which “RT3 transition replay” as the RT3 transition symbol is stopped in the game where each “RT2 push order replay” of “12” is won, and each “RT3 push order of the winning areas“ 03 ”to“ 06 ” The stop operation sequence in which “RT4 transition replay”, which is the RT4 transition symbol, is stopped in a game in which “Replay” is won is referred to as a correct answer pressing order at the time of “push order replay” winning.

  FIG. 19 is a conceptual diagram of each reeling effect determination table (AD). The spinning effect is an effect that fluctuates each reel 12 in a predetermined manner, and is executed during a period from when the game start operation is performed until each reel 12 is in a steady rotation. As shown in FIG. 19, each turning effect determination table is referred to according to the winning area. Specifically, in the game in which the winning area “27” (weak watermelon) or the winning area “29” (weak cherry) is won, the spinning effect determination table A in part (a) of FIG. 19 is referred to. Further, in the game where the winning area “28” (strong watermelon) is won, the turning effect determination table B in part (b) of FIG. 19 is referred to, and the winning area “30” (strong cherry) or the winning area “31” is referred to. In the game where “(weak chance)” is won, the rotation effect determination table C in part (c) of FIG. 19 is referred to, and in the game where the winning area “32” (strong chance) is won, FIG. Reference is made to the rotating effect determination table D of the part (d).

  In the game where the winning areas “27” to “32” are won, the rotating effect determination process is executed using the rotating effect determination table corresponding to the winning area. On the other hand, in the game in which the winning areas “00” to “26” are determined, the spinning effect determining process is not executed. That is, the spinning effect is not executed in the game in which the winning areas “00” to “26” are determined. Therefore, even if the player is in a period before the stop operation of each reel 12, any one of the winning areas “27” to “32” is determined by the internal lottery process when the spinning effect is executed. Can be understood. In addition, in this embodiment, although the rotation effect determination table was provided for every winning area, you may provide for every winning combination, for example.

  As shown in FIG. 19, each turning effect determination table includes a plurality of turning effect numbers and lottery values corresponding to each turning effect number. Each lottery value is a numerical value that is subtracted from the random value R2 in the spinning effect determination process. In the rotation effect determining process, each lottery value is sequentially subtracted from the random value R2 in the order of the rotation effect number, and the rotation effect number when the result of the subtraction becomes a negative number is determined. The rotation effect number indicates the type of the rotation effect to be executed. The rotation effect number is stored in the rotation effect number storage area of the main RAM 303.

  In the present embodiment, a rotating effect including a short lock effect, a middle lock effect, a long lock effect, and a reverse rotation effect is executed. In the short lock effect, each reel 12 is maintained in a stopped state for a predetermined time length (for example, about 1000 ms) from the time when the start of the game is instructed (the time when the start lever 24 is operated). This is a spinning effect in which each reel 12 is steadily rotated after a lapse. As understood from FIG. 19, the short rock performance is determined as one of the winning areas “weak watermelon”, “weak cherry”, “strong watermelon”, “strong cherry”, “weak chance” or “strong chance”. If executed.

  In the middle lock effect, each reel 12 is maintained in a stopped state for a predetermined time length (for example, about 2000 ms) from the time when the start of the game is instructed, and each reel 12 is steadily rotated after the predetermined time length has elapsed. This is a revolving effect. The length of time during which each reel 12 is stopped is longer in the middle lock effect than in the short lock effect. In the middle rock production, as in the case of the short rock production, “weak watermelon”, “weak cherry”, “strong watermelon”, “strong cherry”, “weak chance” or “strong chance” is selected as the winning area. To be executed.

  In the long lock effect, each reel 12 is maintained in a stopped state for a predetermined time length (for example, about 5000 ms) from the time when the start of the game is instructed, and each reel 12 is steadily rotated after the predetermined time length has elapsed. This is a revolving effect. The length of time that each reel 12 is kept stopped is longer in the long lock effect than in the middle lock effect. As understood from FIG. 19, the long lock effect is executed when any of “strong watermelon”, “strong cherry”, “weak chance”, and “strong chance” is determined as the winning area. That is, unlike the short lock effect and the middle lock effect, the long lock effect is not executed when “weak watermelon” or “weak cherry” is determined as the winning area (that is, when the spinning effect determining table A is referred to). .

  In the reverse rotation effect, each reel 12 is maintained in a stopped state for a predetermined time (for example, about 5000 ms) from the time when the start of the game is instructed. ) Only in the reverse direction (rotation in which the symbol of each reel 12 moves upward as viewed from the player). The reverse rotation effect is executed when “strong chance” is determined as the winning area (that is, when the spinning effect determination table D is referred to). That is, unlike the short lock effect and the middle lock effect, the reverse rotation effect is not executed when “weak watermelon”, “weak cherry”, “strong watermelon”, “strong cherry”, and “weak chance” are determined as the winning areas.

  FIG. 20 is a conceptual diagram of a rotation effect drive table that the main CPU 301 refers to when executing the rotation effect. When the execution of the spinning effect is determined, the main CPU 301 drives each reel 12 in a normal sequence (accelerated and steady rotation) after driving each reel 12 with reference to the spinning effect driving table. The rotating effect drive table includes a short lock drive table shown in part (a) of FIG. 20, a middle lock drive table shown in part (b) of FIG. 20, and a long lock drive table shown in part (c) of FIG. And a reverse rotation drive table shown in part (d) of FIG. The short lock driving table is referred to when executing the short lock effect among the spinning effects. The middle lock drive table is referred to when executing the middle lock effect, the long lock drive table is referred to when executing the long lock effect, and the reverse rotation drive table is referred to when executing the reverse rotation effect. Referenced.

  Each rotating effect drive table is configured to include an interrupt count indicating the number of executions of an interrupt process described later and a rotation direction indicating the rotation direction of the stepping motor. The main CPU 301 executes an interrupt process every 1.49 ms, and measures the number of interrupt processes after the start of the spinning effect. As described above, each stepping motor 101 of each reel 12 rotates by a predetermined angle every time a driving pulse is applied (when the driving pulse is applied once, it rotates by 1/24 frames). When the number of executions of the interrupt process reaches the number of interrupts specified in the spinning effect drive table, a drive pulse for rotating each reel 12 in the rotation direction corresponding to the number of interrupts is given. The rotational direction includes a numerical value “0” and a numerical value “−1”. When the rotation direction is a numerical value “0”, the drive pulse is not applied to the stepping motor 101 even when the interrupt process is executed as many times as the number of interrupts. When the rotation direction is a numerical value “−1”, a drive pulse for rotating each reel 12 in the reverse rotation direction is applied to each stepping motor 101 based on the fact that the interrupt process has been executed for the number of interrupts. In the spinning effect that rotates each reel 12 in the direction of steady rotation, when the rotation direction of the spinning effect drive table is “1”, a drive pulse that rotates each reel 12 in the direction of steady rotation is generated. It is given to each stepping motor 101.

  As shown in part (a) of FIG. 20, in the short lock effect, first, an interruption process is executed until the number of interruptions “671” is reached. That is, during about 1000 ms (1.49 × 671 ms), no driving pulse is applied to the stepping motor, and each reel 12 is maintained in a stopped state. When the number of interruptions reaches “671” times, the short lock effect ends, and each reel 12 rotates normally after being accelerated.

  As shown in part (b) of FIG. 20, in the middle lock effect, each reel 12 is maintained in a stopped state until “1342” times of interruption processing is executed, and then each reel 12 is rotated at a steady rotation. To do. Further, as shown in part (c) of FIG. 20, in the long lock effect, each reel 12 is maintained in a stopped state until “3355” interruption processing is executed. It rotates constantly.

  As shown in part (d) of FIG. 20, in the reverse rotation effect, each reel 12 is maintained in a stopped state until the number of execution times of the interrupt process reaches “3355” times. When “3355” times of interrupt processing are executed, a driving pulse for rotating each reel 12 in the reverse direction is applied to each stepping motor 101. After that, when “20” times of interrupt processing are executed, a drive pulse for rotating each reel 12 in reverse is given. Subsequently, when “10” times of interrupt processing are executed, each reel 12 is A drive pulse for reverse rotation is applied (accelerates each reel 12 in the reverse rotation direction). Thereafter, each time “4” interrupts are executed, a drive pulse is applied to the stepping motor, and each reel 12 rotates in reverse at a constant speed. Finally, each reel 12 is maintained in a stopped state until “10” times of interruption processing is executed, and then each reel 12 rotates in the direction of steady rotation.

  In the main RAM 303, all described later, a display permission bit storage area indicating a combination of symbols permitted to stop on the effective line, a display setting value storage area for storing a numerical value displayed on the setting display section 36, a setting A set value storage area for storing values, a random value R1 storage area for storing random number values R1, a random value R2 storage area for storing random number values R2, and a command storage area for storing commands to be transmitted to the sub-control board 400 , A lamp-related data storage area for storing data indicating various lamp display modes, a winning area storage area for storing a winning area, an unstopped operation counter indicating the number of stop buttons 25 that are not stopped, and each stop button A storage area including a stop order storage area for storing 25 operation orders is provided.

<Each data used by sub CPU>
Hereinafter, various data stored in the sub ROM 413 will be described with reference to the drawings. The sub ROM 413 includes an effect state table shown in FIG. 21, an effect lottery table shown in FIG. 23, an ART lottery table shown in FIG. 24, an ART lottery mode transition table shown in FIG. 25, a specialized game lottery table shown in FIG. Various data including an end-time mode transition table shown in FIG. 8 and an extra lottery table shown in FIGS. 28 and 29 are stored.

  FIG. 21 is a conceptual diagram of an effect state table. The effect state table includes an effect state number. The production state number specifies the production state of the gaming machine 1. An effect state number indicating the current effect state is stored in the effect state storage area of the sub RAM 414. The sub CPU 412 refers to the effect state number in the effect state storage area, and each device including the liquid crystal display device 30 executes. Control the production. FIG. 21 shows the types of RT gaming states in each effect state. As will be described in detail later, the stop operation order of each stop button 25 is appropriately notified in each effect state. As long as the player follows the stop operation order notified, the combination of the effect state and the RT game state is as shown in FIG.

  The performance state includes a normal low probability state, a normal high probability state, a fake state, an ART latent state, an ART start preparation state, an ART state, a specialized game preparation state, an added special state, and an ART end preparation state. In the present embodiment, the normal low probability state, the normal high probability state, the fake state, and the ART latent state are collectively referred to as a normal performance state. FIG. 22 is a diagram for explaining the transition of the effect state.

  As will be described later, the sub CPU 412 executes an effect lottery process for each game. FIG. 23 is a conceptual diagram of an effect lottery table used by the sub CPU 412 in the effect lottery process. The sub CPU 412 determines an effect to be executed in each game using the random number R3 (range 0 to 32767) and the effect lottery table. The effect lottery table is selected according to the winning area determined by the main CPU 301, the spinning effect number, and the effect state number of the sub RAM 414. As shown in FIG. 23, each effect lottery table includes an effect number and each lottery value corresponding to each effect number. Each lottery value is subtracted from the random number R3 in the order of the production number, and the production number when the result of the subtraction becomes a negative number is determined. Further, the effect number determined in the effect lottery process is stored in the effect number storage area of the sub RAM 414.

  FIG. 23 shows each of the cases where the winning area is “losing” and the rotation effect is not executed in the normal production state (normal high probability state, normal low probability state, fake state, ART latent state) in the production lottery table. The production lottery table is excerpted and shown. As understood from FIG. 23, in each effect state of the normal effect state, any one of effect A1 to effect An (n is an integer of 1 or more) is determined. That is, a common type of effect is executed in each effect state of the normal effect state. Therefore, in the game in the normal effect state, the player cannot specify which of the effect states is the current effect state in principle. However, since the probability of selecting “no effect” is different in each effect state (normally low probability state> normally high probability state> fake state> ART latency state), the player can perform from effect A1 to effect An. The present performance state can be estimated from the probability that either one has been executed. Further, for example, the effect An is not determined except in the ART latent state. Therefore, when the production An is determined, the player can specify that the current production state is the ART latent state.

  The sub CPU 412 executes an ART lottery process described later for each game. When winning in the ART lottery process, the player is given the right to enter the ART state. Further, the sub CPU 412 executes the ART lottery process in the ART lottery mode having different winning probabilities. Specifically, the ART lottery process is executed in one of the ART lottery modes of the low probability mode, the high probability mode, and the pullback mode. In the present embodiment, in the game in which the ART lottery process is executed in the low probability mode, the effect state is normally a low probability state. In a game in which the ART lottery process is executed in the high probability mode, the effect state is normally a high probability state. When the performance state is the ART completion preparation state, the ART lottery process is executed in the pullback mode (see FIG. 21). The ART lottery mode referred to in the ART lottery process is stored in the ART lottery mode storage area of the sub RAM 414.

  FIG. 24 is a conceptual diagram of an ART lottery table. As shown in FIG. 24, the ART lottery table includes an ART lottery table referred to in a normal low probability state, an ART lottery table referred to in a normal high probability state, an ART lottery table referred to in a fake state, and an ART. And an ART lottery table referred to in the latent state. The sub CPU 412 executes the ART lottery process using the ART lottery table and the random value R4 (range 0 to 32767). The ART lottery table includes a winning area determined by the internal lottery process of the main CPU 301 and lottery values corresponding to each winning area. The ART lottery process is executed when winning areas “26” to “32” (hereinafter referred to as “ART lottery role”) are won, and is not executed when winning areas “00” to “25” are won.

  In the ART lottery process, the sub CPU 412 subtracts the lottery value corresponding to the winning area of the current game from the random value R4, and grants the right to shift to the ART state when the result of the subtraction becomes a negative number. For example, in a low probability mode game, if the random number R4 is a numerical value “10000” and the winning area is “strong chance role”, the result of subtracting the lottery value “4738” from the random number R4 will not be a negative number. The result of the ART lottery process is unsuccessful. On the other hand, in the high probability mode game, when the random value R4 is “10000” and the winning area is “strong chance role”, the result of subtracting the lottery value “15688” from the random value R4 is a negative number. , ART wins.

  When the ART lottery process is won, the effect state shifts to the ART latent state ((A) in FIG. 22). The ART latent state ends when, for example, a predetermined number of games are executed. When the ART latent state ends, the state shifts to an ART start preparation state ((B) in FIG. 22). In the ART start preparation state, when the RT3 transition symbol stops on the active line, the effect state transitions to the ART state ((C) of FIG. 22).

  On the other hand, when the result of the ART lottery process is non-winning, the effect state shifts to the fake state ((D) in FIG. 22). As described above, the fake state has a higher frequency of production than the normal low probability state and the normal high probability state, similarly to the ART latent state. In the game where the ART lottery (for example, cherry) is won, even if the ART lottery process is not won, the same as in the case of winning in the ART lottery process (when shifting to the ART latent state) Increases frequency. Therefore, since it becomes difficult to determine whether or not the ART lottery process has been won, even if the ART lottery process is not won, it is possible to maintain a sense of expectation for winning the ART lottery process. . The fake state ends when, for example, a predetermined number of games are executed. When the fake state is finished, the normal low probability state or the normal high probability state is shifted according to the ART lottery mode ((E) in FIG. 22).

  In addition to the case of winning in the ART lottery process, the ART latent state shifts when a predetermined number of games have been performed after the ART end preparation state is ended and the normal game state is entered ((FIG. 22 ( B)). Specifically, when the value of the game counter subtracted for each game reaches “0”, the effect state shifts to the ART latent state. For example, a numerical value “1000” is set in the game counter as an initial value. According to the above configuration, when the ART lottery process is not won in 1000 games, the effect state shifts to the ART state via the ART start preparation state. The game counter is a storage area in the sub RAM 414.

  FIG. 25 is a conceptual diagram of an ART lottery mode transition table. When the ART lottery mode is a game in the low probability mode and the winning area “18” to “32” (hereinafter referred to as “mode transition lottery”) is won, the sub CPU 412 executes a mode transition lottery process described later. On the other hand, when the winning areas “00” to “17” are won, the sub CPU 412 does not execute the mode shift lottery process. In the mode transition lottery process, the sub CPU 412 subtracts the lottery value corresponding to the winning area won in the current game from the random value R5 (range 0 to 32767). When the result of the subtraction becomes a negative number, the sub CPU 412 changes the ART lottery mode from the low probability mode to the high probability mode ((F) in FIG. 22). On the other hand, when the lottery value is subtracted from the random value R5 and the result of the subtraction does not become a negative number, the ART lottery mode is maintained in the low probability mode.

  In each game in which the ART lottery mode is the high probability mode, the sub CPU 412 determines whether or not to change the ART lottery mode to the low probability mode when the winning area “00” to “17” is won by the mode transition lottery process. decide. For example, in the mode transition lottery process, when the random number R5 is smaller than the numerical value “3278”, the ART lottery mode is changed from the high probability mode to the low probability mode ((G) in FIG. 22).

  FIG. 26 is a conceptual diagram of the specialized game lottery table. The sub CPU 412 executes the specialized game lottery process when the winning area “27” to “32” (hereinafter referred to as “specialized game lottery”) is won in the ART state game. The specialized game lottery table includes a winning area and lottery values corresponding to the winning areas. In the specialized game lottery process, the sub CPU 412 determines whether or not to give the player the right to shift to the specialization state by using the random value R6 (range 0 to 32767) and the specialized game lottery table. To do. When winning in the specialized game lottery process, the effect state shifts to the specialized game preparation state ((H) in FIG. 22). In the specialized game preparation state, when the RT4 transition symbol (RT4 transition replay or 7-match replay) stops on the active line, the effect state transitions to the specialization state (FIG. 22 (I)).

  In the added special state, when the RT3 transition symbol (RT3 transition replay) stops at the active line, the effect state transitions to the ART state ((J) in FIG. 22). The RT3 transition symbol stops at the active line in the game in which the winning area “Additional Game Fall Replay” is won in the specialization state. The ART state is ended when the number of remaining games in the ART state becomes “0”. The number of remaining games in the ART state is stored in the ART counter of the sub RAM 414 and is subtracted for each game. When the ART state ends, the effect state shifts to the ART end preparation state ((K) in FIG. 22).

  The ART termination ready state is terminated when the RT1 transition symbol is stopped on the active line. That is, when the winning combination “upper bell” is missed, the ART completion preparation state ends. When the ART termination preparation state is terminated, the sub CPU 412 executes a termination mode transition lottery process. FIG. 27 is a conceptual diagram of an end mode shift table used for the end mode shift lottery process. In the end mode transition lottery process, the sub CPU 412 determines the ART lottery mode to be the low probability mode or the low probability mode using the end mode transition table and the random value R5. As shown in FIG. 27, the end mode transition table includes each lottery value corresponding to each ART lottery mode. Each lottery value in the end mode transition table is subtracted from the random value R5 in the order of the low probability mode and the high probability mode, and the ART lottery mode in which the result of the subtraction becomes a negative number is determined. When the ART end state ends, the effect state shifts to the fake state ((L) in FIG. 22).

  In the ART state and the extra special state, the sub CPU 412 executes the extra lottery process. In the extra lottery process, the number of extra games to be added to the ART counter is determined. 28 and 29 are conceptual diagrams of the extra lottery table referred to in the extra lottery process.

  FIG. 28 is a conceptual diagram of an extra lottery table used in the extra lottery process in the ART state. In the ART state, when winning areas “27” to “32” are won, an extra lottery process is executed. The sub CPU 412 determines the number of additional games using the random number 7 (range 0 to 32767) and the extra lottery table. The extra lottery table includes a winning area and a lottery value corresponding to each winning area.

  As shown in FIG. 28, the number of extra games determined in the extra lottery process in the ART state is one of “0 game”, “5 game”, “10 game”, “30 game”, and “50 game”. Each lottery value when each winning area wins is distributed for each additional game number. In the extra lottery process, the random number value 7 is subtracted from the lottery value of the extra game number “0 game” in the order of the lottery value of the extra game number “50 game”, and the extra game number in which the result of the subtraction becomes a negative number is determined. Is done. For example, when the random number 7 is “10000” and the winning area is “weak watermelon”, when the lottery value “20030” of the additional game number “0 game” is subtracted to the random number value 7, the result of the subtraction becomes a negative number. Become. In the above case, “0 game” (that is, no additional game) is determined as the additional game number. As another example, when the random number 7 is “10000” and the winning area is “weak chance”, the lottery value “8192” of the additional game number “0 game” is subtracted from the random value 7 (10000-8192 = Furthermore, when the lottery value “29498” of the additional game number “10 games” is subtracted, the result of the subtraction becomes a negative number. In the above case, the number of additional games is determined to be “10 games”. In addition, the structure which determines the number of additional games is not limited to the aspect mentioned above. For example, it is determined by lottery whether or not the added game number is added to the remaining game number, and when the lottery is won, the added game number larger than “0 game” (for example, “5 games” to “50 games”) is set. It is good also as a structure to determine.

  FIG. 29 is a conceptual diagram of the extra lottery table in the extra special state. The sub CPU 412 executes the extra lottery process when the winning areas “27” to “32” are won in the extra special state as in the ART state. In addition, the sub CPU 412 executes the extra lottery process when the winning area “01” and the winning areas “18” to “26” are won in addition to the winning areas “27” to “32” in the extra special state. To do. Therefore, the probability that the extra lottery process is executed in each game is higher in the extra special state than in the ART state. Further, as understood from FIG. 29, the expected value of the number of added games selected in the game won in each winning area is larger in the added specialized state than in the ART state. That is, the added special state is an effect state in which the expected value of the number of added games obtained in each game is larger than that in the ART state.

  Depending on the performance state and the RT gaming state, the sub CPU 412 notifies the active line of a stop operation sequence in which a specific winning combination or RT transition symbol stops. FIG. 30 is a diagram for explaining a stop operation sequence that is notified in accordance with the combination of the effect state and the RT gaming state. For example, when the production state is the ART state and the RT gaming state is the RT3 gaming state, the stop operation order for stopping the normal replay on the active line and the stop operation order for stopping the middle bell on the active line are notified. In FIG. 30, the RT0 gaming state is omitted from the RT gaming state. In the present embodiment, in principle, the RT gaming state does not transition again to the RT0 gaming state in the game after transitioning from the RT0 gaming state to the RT1 gaming state. In the RT0 gaming state, the stop operation order is not notified.

  As shown in FIG. 30, the stop operation order is not notified in the normal performance state. In the present embodiment, in a gaming state in which the stop operation order is not notified, when a stop operation other than the stop button 25L is first performed among the stop buttons 25, a warning is issued to the player. For example, the sub CPU 412 displays a message “please press from the left reel” on the liquid crystal display device 30 to give a warning. Therefore, in principle, the player performs a stop operation on the stop button 25L first in a gaming state in which the stop operation order is not notified. In addition, in the game state where the stop operation order is not notified, when a button other than the stop button 25L is first operated, a game penalty may be given to the player in addition to the above-described warning. For example, a configuration in which the ART lottery process is not performed even if the ART lottery is won in the internal lottery process until a predetermined period (for example, a period of five games) elapses after the operation other than the stop button 25L is stopped can be adopted. .

  In the RT1 gaming state, as described above, the winning area “RT1 push order replays 1 to 4” is won (FIG. 9). Also, “RT2 transition replay” which is the RT2 transition symbol does not stop on the active line as long as the stop button 25L is first stopped (FIG. 17). Therefore, in the normal performance state, the stop button 25L is stopped first, so it is a principle to stay in the RT1 gaming state. On the other hand, if the player ignores the warning and performs a stop operation other than the stop button 25L for the first time, the player can enter the RT2 gaming state, the RT3 gaming state, or the RT4 gaming state even in the normal performance state. In the normal performance state, the stop operation order is not notified even when the game state transitions to an RT game state other than the RT1 game state. In FIG. 30, fields corresponding to RT gaming states in which each staying state stays in principle are indicated by a thick frame.

  As shown in FIG. 30, in the ART start preparation state, the correct answer push order (stop operation order) in which the RT2 transition replay stops at the valid line, the correct push order in which the RT3 transition replay stops at the valid line, and the middle bell are valid lines. The correct answer pressing order to be stopped is notified. Specifically, in a game in the ART start preparation state, in the game immediately after the transition of the performance state from the normal performance state (ART latent state) (RT1 game state), the stop operation sequence in which the RT2 transition replay stops and the middle stage The stop operation order in which the bell stops is notified. In addition, in a game in an ART start preparation state after the RT2 transition replay is stopped on the active line (RT2 game state), the stop operation order in which the RT3 transition replay stops and the stop order in which the middle bell stops Inform. In other words, in a game in the ART start preparation state and the winning area “RT1 push order replays 1 to 4” is won, the correct answer push order of the RT2 transition replay which is the RT2 transition symbol is notified. In addition, in a game in an ART start preparation state and a game in which the winning area “RT2 push order replays 1 to 6” is won, the correct answer push order of the RT3 transition replay which is the RT3 transition symbol is notified.

  Further, in a game in an ART start preparation state, in which the winning area “push order bells A1 to A4, B1 to B4” is won, the correct answer push order for stopping the middle bell on the active line is notified. As described above, in the game where the winning area “push order bells A1 to A4, B1 to B4” is won, the RT1 transition symbol may stop when the stop operation is performed in a direction other than the correct answer push order. When the RT1 transition symbol stops on the active line in the RT2 gaming state, the RT gaming state transitions (falls) to the RT1 gaming state. On the other hand, in the game where the winning area “push order bells A1 to A4, B1 to B4” is won, when the stop operation is performed in the correct push order, the middle bell stops on the active line and the RT1 transition pattern does not stop. (FIG. 18). As understood from the above description, in the ART start preparation state after the RT gaming state shifts to the RT2 gaming state, the RT gaming state is set to RT2 by the player performing a stop operation in the notified correct answer pressing order. The game state is maintained.

  In the ART start preparation state, the middle bell is stopped on the active line to maintain the RT2 gaming state, but the notification of the stop operation sequence in which the RT3 transition symbol stops is ignored and the state is not shifted to the ART state (that is, the ART state). (Because it does not start subtracting the number of remaining games) From the viewpoint of preventing the above fraudulent acts, when the notification of the stop operation order of the RT3 transition symbol is ignored, a game penalty may be given. For example, a penalty is provided to stop the notification of all stop operation orders for a predetermined number of games.

  As shown in FIG. 30, in the ART state, the stop operation order in which the normal replay stops on the active line and the correct push order in which the middle bell stops on the active line are notified. In the ART state, as in the ART start preparation state, the correct push order of the middle bell is notified in the game in which the winning area “push order bells A1 to A4, B1 to B4” is won. As described above, the winning probability of the re-gamer in the RT3 gaming state is higher than that in the RT1 gaming state. In the ART state, the player performs a stop operation in the notified correct answer push order to stop the middle bell on the active line and acquire a medal, and the winning probability of the re-gamer is compared with the RT1 game state. High RT3 gaming state can be maintained.

  In the ART state, for example, the stop operation may be performed in a stop operation order different from the notified correct push order due to the carelessness of the player. When the winning area “push order bells A1 to A4, B1 to B4” is won and the stop operation is performed in an order other than the correct answer push order, the RT gaming state shifts from the RT3 gaming state to the RT1 gaming state (falls). there's a possibility that. As shown in FIG. 30, in the ART state, when the RT gaming state shifts to the RT1 gaming state, the correct pressing order of the RT2 transition replay is notified together with the correct pressing order of the middle bell. In the ART state, when the RT gaming state shifts to the RT2 gaming state, the correct pressing order of the RT3 transition replay is notified together with the correct pressing order of the middle bell. Therefore, even when the state shifts to the RT1 gaming state in the ART state, the RT gaming state shifts (returns) to the RT3 gaming state by performing the stopping operation in the notified stop operation order.

  The sub CPU 412 may be configured not to execute the extra lottery process during the period from the transition to the RT1 gaming state to the return to the RT3 gaming state. In addition, the player may be notified that the game is returning to the RT3 gaming state during the period from the transition to the RT1 gaming state to the return to the RT3 gaming state. For example, a configuration in which a message “RT state is being restored” is displayed on the liquid crystal display device 30 is considered. Further, the subtraction of the remaining number of games in the ART state may be stopped until the RT1 gaming state returns to the T3 gaming state.

  As shown in FIG. 30, in the specialized game preparation state, the correct push order in which the RT4 transition replay stops on the active line and the correct push order in which the middle bell stops on the active line are notified. In other words, when the special game lottery process is won in the ART state and the production state shifts to the special game preparation state, the winning area “RT3 push order replay” is changed to the stop operation order for stopping the normal replay in the game won. Thus, the stop operation order (correct answer pressing order) for stopping the RT4 transition replay on the active line is notified. As understood from FIG. 30, in the specialized game preparation state, as in the ART state, when the transition is made to the RT1 gaming state, the stop operation order for returning the RT gaming state to the RT3 gaming state is notified. In the specialized game ready state, the middle bell is stopped on the active line and the RT3 game state is maintained, but the notification of the stop operation order in which the RT4 transition symbol stops is ignored and the illegal action is not added to the specialized state. Is assumed. From the viewpoint of preventing the above fraudulent acts, when the notification of the stop operation sequence of the RT4 transition symbol is ignored, a game penalty may be given. For example, a penalty is provided to stop the notification of all stop operation orders for a predetermined number of games.

  As shown in FIG. 30, the stop operation sequence in which the middle bell stops at the active line in the added special state is notified. In the RT4 gaming state, the winning area for the push order replay is not won (FIG. 9). Therefore, in the RT4 gaming state which is shifted when the RT4 transition symbol is stopped on the active line, in principle, the stop operation order is not notified when the winning area of the push order replay is won. However, in the added special state, when transitioning to the RT1 game state, the stop operation order for returning to the RT4 game state (including the stop operation order when the winning area of the push order replay is won) is notified. As described above, in the game where the winning area “Specialized Game Fall Replay” is won, regardless of the stop operation order, the RT3 transition symbol (RT3 transition replay) stops at the active line, and the specialization state is completed. To the ART state.

  As shown in FIG. 30, the stop operation order is not notified in the ART completion preparation state. The sub CPU 412 executes the ART lottery process in the ART completion preparation state (RT3 gaming state) as in the normal gaming state. When the ART lottery process is won, the production state shifts from the ART completion preparation state to the ART latent state (normal production state). In the ART latent state, the correct push order of the middle bell is not notified. Therefore, when the ART lottery is won in the ART end preparation state, the RT gaming state normally shifts to the RT1 gaming state. The ART latent state ends and the state shifts to the ART start preparation state. Then, in the ART start preparation state, the RT3 transition symbol stops at the active line, and the ART state (RT3 gaming state) resumes. When the ART lottery is won in the ART completion preparation state, the effect state may be returned to the ART state without going through the ART latent state. As described above, the RT gaming state in the ART end preparation state is the RT3 gaming state, and is common to the ART state. Therefore, when returning from the ART end preparation state to the ART state without going through the ART latent state, it is not necessary to change the RT gaming state.

  The sub RAM 414 stores data generated by the sub CPU 412 executing each process and data to be updated in each storage area. Specifically, an effect state storage area for storing an effect state number indicating an effect state, an effect number storage area for storing an effect number indicating the type of effect executed in each game, a game counter indicating the number of games, and an ART state The sub RAM 414 includes various storage areas including an ART counter indicating the number of remaining games and an RT type storage area for storing the RT game state type.

<Each process executed by the main CPU>
The main CPU 301 executes various processes with reference to the various data described above. FIG. 31 is a flowchart of the startup process of the main CPU 301. The main CPU 301 executes start-up processing when a reset signal is input from a reset circuit (not shown). The reset circuit outputs a reset signal when the power supply voltage supplied to the main control board 300 exceeds a predetermined threshold. For example, when the supply of the power supply voltage to the main control board 300 is started by turning on the power switch 511SW, the activation process is executed.

  When the activation process is started, the main CPU 301 initializes each register and peripheral circuit of the main control board 300 (S1). Note that the main CPU 301 may execute a security check process for determining the validity of a control program stored in the main ROM 302 before initializing each register and peripheral circuit.

  The main CPU 301 determines whether or not the setting switch is in an ON state (S2). The setting switch is turned on when a setting key (not shown) is inserted into a keyhole provided inside the gaming machine 1 and rotated. When the main CPU 301 determines that the setting switch is in the ON state (S2: YES), the main CPU 301 sets a setting change start command in the command storage area of the main RAM 303 (S3), and proceeds to the setting change process shown in FIG.

  On the other hand, when determining that the setting switch is not in the ON state (S2: NO), the main CPU 301 determines whether a backup flag is stored in the main RAM 303 (S4). In the present embodiment, when the power supply voltage supplied to the main control board 300 falls below a predetermined threshold (when the power is shut off), the main CPU 301 backs up each data stored in the main RAM 303 and A backup flag is stored in the RAM 303. That is, if the backup is normally executed when the power is turned off, the backup flag is stored in the main RAM 303.

  When determining that the backup flag is stored (S4: YES), the main CPU 301 calculates the checksum of the data stored in the main RAM 303 (S5). In the present embodiment, the checksum of the main RAM 303 is calculated and stored even when the power is turned off, as in step S4 of the startup process.

  The main CPU 301 determines whether or not the checksum calculated at step S4 (checksum at power-on) matches the checksum calculated at power-off (S6). If the data in the main RAM 303 is held without change during the period from when the power is turned off to when it is turned on, the checksum when the power is turned on matches the checksum when the power is turned off. On the other hand, if the data in the main RAM 303 changes (deteriorates) during the period from when the power is turned off to when it is turned on, the checksum when the power is turned on does not match the checksum when the power is turned off.

  When the main CPU 301 determines that the checksum at power-on and the checksum at power-off coincide with each other (S6: YES), the time when the power is shut down (backup is backed up) based on each data stored in the main RAM 303. Each register is returned to the state at the time of execution (S7). By returning the state of each register, the main control board 300 returns to the state at the time when the power is shut off. When the main CPU 301 restores the state of each register (the state of the main control board 300), the main CPU 301 resumes the processing from the step at the time when the power is shut off. When the main CPU 301 returns the state of the main control board 300, the main CPU 301 transmits various information (for example, an RT type command described later) necessary to return the effect state of the gaming machine 1 to the sub control board 400.

  As shown in FIG. 31, when determining that the backup flag is not stored (S4: NO), the main CPU 301 determines that the checksum when the power is turned on does not match the checksum when the power is turned off. In the case (S6: NO), a main RAM abnormality flag indicating abnormality of the main RAM 303 is set (S8). That is, the main RAM abnormality flag is set when the backup cannot be executed or when the data in the main RAM 303 changes during the period when the power is cut off. During the period when the main RAM abnormality flag is set, the main CPU 301 notifies the abnormality of the main RAM using, for example, the main display ML. The main RAM abnormality flag is cleared, for example, when the set value changing process is normally executed.

  After setting the main RAM abnormality flag, the main CPU 301 proceeds to RAM error processing. In the RAM error processing, the progress of the game is prohibited. In the RAM error processing, the main CPU 301 may transmit a command for notifying the abnormality of the main RAM 303 to the sub-control board 400, and the liquid crystal display device 30 may display a warning screen, for example.

  FIG. 32 is a flowchart of the setting change process. When the setting change process is started, the main CPU 301 determines whether or not the front door 3 is opened (S11). For example, a door sensor that outputs an OFF signal when the front door 3 is closed and outputs an ON signal when the front door 3 is opened is provided, and the front door 3 is opened according to a signal from the door sensor. A configuration in which the main CPU 301 determines whether or not it is present can be employed. As described above, since the setting switch (the keyhole of the setting key) is provided inside the gaming machine 1, the setting change process is usually executed during the period when the front door 3 is opened. Therefore, when the setting change process is executed in a state where the front door 3 is closed, it is assumed that an ON signal of the setting switch and the power switch SW is input due to an illegal act. If it is determined that the front door 3 is not opened in consideration of the above circumstances (S11: NO), the main CPU 301 sets the setting switch abnormality flag to the ON state (S12), and proceeds to setting switch error processing. To do. In the setting switch error process, the progress of the game is prohibited. Further, in the setting switch error process, the main CPU 301 may transmit an error command for notifying the abnormality of the setting switch to the sub-control board 400, and the liquid crystal display device 30 may display a warning screen, for example. The setting switch abnormality flag is cleared when the starting process is started again and the setting value changing process is normally executed.

  On the other hand, when determining that the front door 3 is opened (S11: YES), the main CPU 301 displays a numerical value corresponding to the set value on the setting display unit 36 (S13). Specifically, the main CPU 301 displays a numerical value stored in the display setting value storage area of the main RAM 303 on the setting display unit 36.

  The main CPU 301 determines whether or not the setting change button 37 has been operated (S14). Specifically, the main CPU 301 determines whether or not an ON signal is input from the setting change switch 37SW. If it is determined that the setting change button 37 has been operated (S14: YES), the main CPU 301 increments the numerical value stored in the display setting value storage area of the main RAM 303 (S15), and the process proceeds to step S16. On the other hand, if it is determined that the setting change button 37 has not been operated (S14: NO), the main CPU 301 proceeds to step S16 without incrementing the numerical value in the display setting value storage area.

  In step S16, the main CPU 301 determines whether or not the start lever 24 has been operated. Specifically, the main CPU 301 determines whether or not an ON signal of the start switch 24SW is input. As understood from FIG. 32, the main CPU 301 repeats the processing from step S13 to step S15 until it is determined that the start lever 24 has been operated (S16: NO). As understood from the above description, every time the setting change button 37 is operated and the numerical value in the display setting value storage area is added in step S15, the numerical value displayed on the setting display unit 36 is added in step S13. .

  On the other hand, when determining that the start lever 24 has been operated (S16: YES), the main CPU 301 determines the numerical value displayed on the setting display unit 36 as a setting value (S17). Specifically, the main CPU 301 stores the numerical value stored in the display setting value storage area in the setting value storage area of the main RAM 303. Further, the main CPU 301 transmits the determined setting value to the sub control board 400. The sub CPU 412 stores the setting value received from the main CPU 301 in the sub RAM 414.

  When determining the set value, the main CPU 301 ends the set value change process and executes the game process. The main CPU 301 transmits a setting change start command indicating the start of the setting change process to the sub control board 400 to notify the sub control board 400 that it is the execution period of the setting change process. In addition, when the sub CPU 412 of the sub control board 400 receives a setting value command indicating the determined setting value, the sub CPU 412 ends the notification of the execution period of the setting change process.

  FIG. 33 is a flowchart of the game control process of the main CPU 301. The game control process is executed every time the player plays a game. As will be described in detail later, the main CPU 301 executes an interrupt process (see FIG. 51) at a predetermined time interval (eg, 1.49 ms) during a period in which the game control process is executed. That is, the main CPU 301 alternately executes the game control process and the interrupt process at predetermined time intervals. As will be described in detail later, for example, a command (for example, a start operation command described later) transmitted to the sub control board 400 is set in the game control process and transmitted to the sub control board 400 in the interrupt process. In addition, a timer (for example, a wait timer) set in the game control process is subtracted in the interrupt process.

  When starting the game control process, the main CPU 301 executes an initial setting process (S101). The initial setting process in step S101 is executed every time one game is completed. Of the storage areas of the main RAM 303, the storage area that is initialized for each game is initialized by this processing.

  After the initial setting process, the main CPU 301 shifts the process to the automatic insertion process (S102). As a result of the previous game, when the re-game players are aligned on the active line, the same number of betting medals as the previous game are set by the automatic insertion process.

  The main CPU 301 shifts the processing to the pre-game start processing (S103) after the automatic insertion processing. In the pre-game process, the main CPU 301 detects a medal from the medal insertion unit 8 and detects an operation of the settlement button 23. Further, the main CPU 301 detects an operation of the start lever 24 (that is, a game start operation) in the pre-game start process.

  When the main CPU 301 detects a game start operation in the pre-game start process, the main CPU 301 executes a set value check process (S104). In the setting value confirmation process, the main CPU 301 determines whether the setting values stored in the setting value storage area of the main RAM 303 are appropriate. Specifically, the main CPU 301 determines whether or not the setting value stored in the setting value storage area is within the range of the numerical value “1” to the numerical value “6” in the setting value confirmation process. When the main CPU 301 determines that the set value is not within the range of the numerical value “1” to the numerical value “6”, the main CPU 301 sets a set value abnormal command that means an abnormal set value, and processes the set value error process (not shown). To migrate. For example, when the setting value stored in the setting value storage area is changed due to noise, a setting value error process is executed. In the set value error process, the main CPU 301 stops the game control process (prohibits the progress of the game). When the setting value error process is executed, for example, the power button 511 is turned off and then turned on again, and the main CPU 301 is caused to execute the startup process and the setting change process to set a normal setting value. Then, it returns to the state where the game is possible.

  When the main CPU 301 detects a game start operation, the main CPU 301 acquires a random value R1 and a random value R2 (S105). The random value R1 is a hardware random number generated by the random number generator 304 and is used in the internal lottery process. The random value R2 is a software random number acquired from a register built in the main CPU 301, and is used in the later-described spinning effect control process. For example, a register value that is incremented each time the main CPU 301 executes each step of the game control process is suitably employed as the random value R2. The main CPU 301 stores the acquired random number value R1 in the random number value R1 storage area of the main RAM 303. Similarly, the main CPU 301 stores the acquired random number value R2 in the random number value R2 storage area of the main RAM 303.

  The main CPU 301 executes the internal lottery process (S106) after storing the random number value R1 and the random number value R2 in the main RAM 303. In the internal lottery process, the winning area is determined based on the random value R1 generated by the random number generator 304 and the winning area lottery table (FIGS. 9 to 13).

  After executing the internal lottery process, the main CPU 301 executes the spinning effect control process (S107). As described above, the main CPU 301 causes each reel 12 to execute the spinning effect. In the rotation effect control process, whether or not to execute the rotation effect is determined using the random number R2 and the rotation effect determination table (FIG. 19).

  The main CPU 301 executes the wait process (S108) after executing the internal lottery process. The wait process is a process for making the period from the start operation of the game until the operation of each stop button 25 is permitted longer than a predetermined time length. For example, in the wait process, it is determined whether or not a predetermined wait period has elapsed, and if it is determined that the wait period has not elapsed, the process is not shifted from the wait process to the pre-stop process described below (S109). .

  The main CPU 301 executes pre-stop processing (S109) after executing the wait processing. In the pre-stop process, various types of data (priority order described later) are stored in the main RAM 303 according to the winning area determined in the internal lottery process. In the stop control process described later, the reel is stopped according to each data stored in the pre-stop process, so that the winning combination designated in the winning area is stopped and displayed on the active line.

  After executing the pre-stop process, the main CPU 301 executes the stop control process (S110). In the stop control process, each time each stop button 25 is operated, the reel 12 corresponding to the operated stop button 25 is stopped. Each reel 12 is stopped at a stop position corresponding to each data set in the pre-stop processing described above.

  When all the reels 12 are stopped by the stop control process, the main CPU 301 executes a display determination process (S111). In the display determination process, the main CPU 301 determines the combination of symbols displayed on the active line. Also, the main CPU 301 sets various data according to the type of combination of symbols displayed on the determined effective line. For example, when it is determined that the re-game players are on the active line, the main CPU 301 sets the re-game operation flag to the ON state. When the main CPU 301 determines in the display determination process that the winning winning combination is stopped on the active line, the main CPU 301 adds the number of medals according to the type of the winning winning combination to the credit amount or pays out from the hopper 520. .

  After executing the display determination process, the main CPU 301 executes the RT gaming state transition process (S112). In the RT gaming state transition process, the main CPU 301 updates the RT gaming state according to the combination of symbols displayed on the active line. For example, when a combination of symbols for changing the RT gaming state is displayed on the activated line, the main CPU 301 changes the RT gaming state according to the displayed combination of symbols. When the main CPU 301 finishes the RT gaming state transition process, the main CPU 301 returns the process to step S101.

  FIG. 34 is a flowchart of the initial setting process at the end of the game. In the initial setting process, the main CPU 301 initializes a storage area for storing information necessary for one game in the storage area of the main RAM 303 (S101-1). For example, the winning area storage area storing the winning area of the previous game is initialized by the initial setting process.

  After initializing the main RAM 303, the main CPU 301 determines whether or not the auxiliary storage unit 530 is full (S101-2). That is, the main CPU 301 determines whether or not the ON signal from the full sensor 530SE is input. When it is determined that the auxiliary storage unit 530 is full (S101-2: YES), the main CPU 301 sets a full tank error command (S101-3), and proceeds to full tank error processing.

  In the full tank error process, the main CPU 301 notifies the full tank error using the payout number display 16. For example, during the period of executing the full tank error process, the main CPU 301 displays characters “HF” (hopper full) on the payout number display 16. In addition, it is good also as a structure which alert | reports a full tank error with another indicator (for example, the stored number indicator 17). When the main CPU 301 determines that the auxiliary storage unit 530 is not full (S101-2: NO), the main CPU 301 ends the pre-game start process and shifts to an automatic input process.

  FIG. 35 is a flowchart of the automatic loading process. When starting the automatic insertion process, the main CPU 301 determines whether or not there are re-game players on the active line in the previous game (S102-1). Specifically, the main CPU 301 determines whether or not the re-game in-operation flag is set in the display determination process (S109) of the previous game control process. When the re-game players are not aligned on the active line in the previous game (S102-1: NO), the main CPU 301 ends the automatic insertion process.

  On the other hand, when it is determined in the previous game that the re-game players are aligned on the active line (S102-1: YES), the main CPU 301 stores the automatic medal insertion command in the command storage area of the main RAM 303 (S102-). 2). The medal automatic insertion command indicates that one betting medal is automatically inserted. In each automatic insertion process, an automatic insertion command equal to the number of betting medals in the previous game is transmitted to the sub-control board 400.

  After storing the medal automatic insertion command, the main CPU 301 sets an automatic insertion timer (S102-3). The automatic insertion timer is a timer for ensuring a time interval at which the automatic medal insertion command is transmitted to the sub control board 400 to a predetermined time length or more.

  When the automatic charging timer is set, the main CPU 301 determines whether or not the automatic charging timer has expired (S102-4). The main CPU 301 repeats step S102-3 until it determines that the automatic charging timer has expired (S102-4: NO).

  When it is determined that the automatic insertion timer has expired (S102-4: YES), the main CPU 301 adds a numerical value “1” to the betting number counter (S102-5). The betting number counter indicates the number of betting medals for the current game. Further, the main CPU 301 generates BET lamp display data indicating the display mode of the BET lamp 14 (14a, 14b, 14c) according to the value of the betting number counter (S102-6). Specifically, when the betting number counter is a numerical value “1”, BET lamp display data for lighting one lamp 14 a out of the BET lamps 14 is generated. Similarly, when the betting number counter is “2”, BET lamp display data for turning on one lamp 14a and two lamps 14b among the BET lamps 14 is generated, and when the betting number counter is “3”. Generates BET lamp display data for lighting one lamp 14a, two lamps 14b, and three lamps 14c among the BET lamps 14. BET lamp display data is stored in a lamp-related data storage area of the main RAM 303.

  The main CPU 301 determines whether or not the value of the bet number counter matches the bet medal of the previous game (S102-7). The main CPU 301 repeats the processing from step S102-2 to step S102-6 until it is determined that the value of the betting number counter matches the bet medal of the previous game (S102-7: NO). On the other hand, when it is determined that the value of the betting number counter matches the bet medal of the previous game (S102-7: YES), the main CPU 301 ends the automatic insertion process. As understood from the above description, if the re-game players are aligned on the active line as a result of the previous game, the same bet medal as the bet medal of the previous game is set in the current game.

  FIG. 36 is a flowchart of pre-game start processing. When the main CPU 301 starts the pre-game start process, the main CPU 301 sets a prescribed number with reference to the game state flag in the game state storage area of the main RAM 303 (S103-1). In this embodiment, the game state is a normal game state for any game. In the game in the normal gaming state, the prescribed number is set to a numerical value “3”.

  After setting the specified number according to the gaming state, the main CPU 301 proceeds to the inserted medal acceptance process (S103-2). In the inserted medal acceptance process, the main CPU 301 accepts a medal from the medal insertion unit 8. Further, when the main CPU 301 receives a medal from the medal insertion unit 8, the main CPU 301 adds a bet number counter or a credit number.

  After executing the inserted medal acceptance process, the main CPU 301 proceeds to the BET operation acceptance process (S103-3). The main CPU 301 receives the player's operation of the 1BET button 21 or the operation of the MAX-BET button 22 in the BET operation reception process.

  After executing the BET operation reception process, the main CPU 301 proceeds to the settlement operation reception process (S103-4). The main CPU 301 receives the player's operation of the payment button 23 in the payment operation reception process.

  The main CPU 301 executes a demonstration display command transmission process (S103-5) after executing the settlement operation acceptance process. In the demonstration display command transmission process, the main CPU 301 determines whether or not a period (non-game period) during which no game operation (insertion of medals or operation of the start lever 24) is accepted is longer than a predetermined time length. If it is determined that the time is longer than the time length, a demonstration display command is transmitted to the sub-control board 400. The demonstration display command causes the liquid crystal display device 30 or the like to execute a demonstration.

  After executing the demonstration display command transmission process, the main CPU 301 determines whether or not the betting number counter is the specified number (S103-6). In the above-described automatic insertion process in step S102, inserted medal reception process in step S103-2, or BET operation reception process in step S103-3, when the betting number counter is added up to the specified number, the main CPU 301 displays the betting number counter. Is the prescribed number (S103-6: YES), the process proceeds to step S103-7.

  In step S103-7, the main CPU 301 determines whether or not the start lever 24 has been operated by the player. When determining that the start lever 24 has been operated (S103-7: YES), the main CPU 301 stores a start operation command in the command storage area of the main RAM 303 (S103-8). When the start operation command is stored, the main CPU 301 ends the pre-game process and proceeds to a set value confirmation process (S104).

  On the other hand, if the betting number counter has not reached the specified number (S103-6: NO) or the start lever has not been operated (S103-7: NO), the inserted medal acceptance process (S103-2) is performed. Each process including the BET operation reception process (S103-3) and the settlement operation reception process (S103-4) is repeatedly executed. That is, the main CPU 301 waits until a game start operation is performed in a state where the medal insertion operation from the medal insertion unit 8, the operation of the MAX-BET button 22, and the operation of the 1BET button 21 can be accepted.

  FIG. 37 is a flowchart of inserted medal acceptance processing. When the inserted medal acceptance process is started, the main CPU 301 determines whether or not the insertion disabled flag is in an ON state (S103-2-1). The insertion impossible flag is set to an ON state in S103-2-8, which will be described later, when the betting number counter is the upper limit value and the credit amount is the upper limit value. When the main CPU 301 determines that the insertion impossible flag is in the ON state (S103-2-1: YES), the main CPU 301 ends the insertion medal acceptance process. On the other hand, if the main CPU 301 determines that the insertion impossible flag is not in the ON state (S103-2-1: NO), the main CPU 301 determines whether or not a medal has been inserted from the medal insertion unit 8 (S103-2-2). .

  Specifically, as described above, a medal inserted from the medal insertion unit 8 is detected by a signal from the medal sensor 34SE. In the present embodiment, the main CPU 301 reads the signal from the medal sensor 34SE in response to the signal from the medal sensor 34SE in the input port reading process (S202) of the interrupt process (FIG. 51) that is periodically executed. Thus, the medal detection flag in the main RAM 303 is set to the ON state. In step S103-2-2, the main CPU 301 determines whether or not the medal detection flag is in an ON state.

  When the main CPU 301 determines that a medal has been inserted from the medal insertion unit 8 (S103-2-2: YES), the main CPU 301 stores an insertion command indicating that a medal has been inserted in the command storage area (S103-2-3). ). Further, the main CPU 301 determines whether or not the betting number counter is a prescribed number of three (S103-2-4). When the bet number counter is not the prescribed number (S103-2-4: NO), the main CPU 301 adds a numerical value “1” to the bet number counter (S103-2-5), and ends the inserted medal acceptance process. On the other hand, when the betting number counter is the prescribed number of three (S103-2-4: YES), the main CPU 301 adds a numerical value “1” to the number of credits (S103-2-6).

  After adding the number of credits, the main CPU 301 determines whether or not the number of credits matches the upper limit “50” (S103-2-7). When the number of credits is “50” (S103-2-7: YES), the main CPU 301 sets the medal insertion disabled flag to the ON state (S103-2-8), and ends the inserted medal acceptance process. On the other hand, when the number of credits is not “50” (S103-2-7: NO), the main CPU 301 ends the inserted medal acceptance process without setting the medal insertion disabled flag to the ON state. During the period when the medal insertion disable flag is set to the ON state, the main CPU 301 controls the selector 34 so that the medal inserted from the medal insertion unit 8 is guided to the outside of the gaming machine 1. Therefore, medals inserted from the medal insertion unit 8 are discharged to the outside of the gaming machine 1 during the period when the medal insertion disable flag is ON.

  FIG. 38 is a flowchart of the BET operation acceptance process. In the BET operation acceptance process, the main CPU 301 determines whether or not the number of credits is a numerical value “0” (S103-3-1). When the number of credits is a numerical value “0” (S103-3-1: YES), the main CPU 301 ends the BET operation acceptance process.

  When the number of credits is not “0” (S103-3-1: NO), the main CPU 301 determines whether or not the 1BET button 21 has been operated (S103-3-2). When it is determined that the 1BET button 21 has been operated (S103-3-2: YES), the main CPU 301 sets a numerical value “1” in the insertion request counter (S103-3-3). In step S103-3-3, the main CPU 301 stores a 1BET operation command for notifying the operation of the 1BET button 21 in the command storage area of the main RAM 303. On the other hand, when determining that the 1BET button 21 has not been operated (S103-3-2: NO), the main CPU 301 determines whether or not the MAX-BET button 22 has been operated (S103-3-4). ). When determining that the MAX-BET button 22 has been operated (S103-3-4: YES), the main CPU 301 sets a numerical value “3” in the insertion request counter (S103-3-5). In step S103-3-5, the main CPU 301 stores a MAX-BET operation command for notifying the operation of the MAX-BET button 22 in the command storage area of the main RAM 303. When determining that the MAX-BET button 22 has not been operated (S103-3-4: NO), the main CPU 301 ends the BET operation acceptance process. In this embodiment, the automatic medal insertion command, medal insertion command, 1 BET operation command, and MAX-BET operation command are collectively referred to as insertion-related commands.

  In step S103-3-3 or step S103-3-5, when a predetermined numerical value is set in the input request counter, the main CPU 301 proceeds to step S103-3-6. Specifically, the main CPU 301 subtracts “1” from the numerical value set in the input request counter (S103-3-6). When “1” is subtracted from the insertion request counter, the main CPU 301 subtracts “1” from the credit counter (S103-3-7), and adds “1” to the betting number counter (S103-3-8). After adding “1” to the betting number counter, the main CPU 301 determines whether or not the betting number counter matches the specified number (S103-3-9). When the bet number counter matches the specified number (S103-3-9: YES), the main CPU 301 ends the BET operation acceptance process. On the other hand, when the betting number counter does not match the specified number (S103-3-9: NO), the main CPU 301 determines whether or not the insertion request counter is a numerical value “0” (S103-3-10). . When the insertion request counter is a numerical value “0” (S103-3-10: YES), the main CPU 301 ends the BET operation acceptance process. On the other hand, when the insertion request counter is not the numerical value “0” (S103-3-10: NO), the main CPU 301 determines whether or not the number of credits is “0” (S103-3-11). When the number of credits is “0” (S103-3-11: YES), the main CPU 301 ends the BET operation acceptance process, and when the credit counter is not “0” (S103-3-11: NO). The process returns to step S103-3-6.

  As understood from the above description, the main CPU 301 receives an operation of the 1BET button 21 (S103-3-2: YES), and receives an operation of the MAX-BET button 22 (S103-3-). 4: YES) when the betting number counter reaches the specified number (S103-3-9: YES), when the insertion request counter is decremented to “0” (S103-3-10: YES), or Until the number of credits becomes “0” (S103-3-11: YES), the process of step S103-3-8 is repeatedly executed to increment the bet number counter.

  FIG. 39 is a flowchart of the settlement operation acceptance process. In the settlement operation acceptance process, the main CPU 301 determines whether or not the settlement button 23 has been operated by the player (S103-4-1). When it is determined that the settlement button 23 has been operated (S103-4-1: YES), the main CPU 301 sets a settlement medal in the payout request counter (S103-4-2). The settlement medal is the sum of the betting number counter and the credit amount at the time when the settlement button 23 is operated. Further, the main CPU 301 stores a settlement operation command indicating the operation of the settlement button 23 in the command storage area of the main RAM 303 (S103-4-3), and sets the medal insertion disable flag to an OFF state (S103-4-4). ).

  When it is determined that the settlement button 23 has not been operated (S103-4-1: NO), the main CPU 301 ends the settlement operation acceptance process. As will be described in detail later, in the hopper driving process, medals of the number of payout request counters are discharged from the hopper 520 to the tray unit 7 through the medal payout exit 9.

  FIG. 40 is a flowchart of the demo display command transmission process. When the demonstration display command transmission process is started, the main CPU 301 determines whether or not the betting number counter is greater than or equal to a numerical value “1” (S103-5-1). When determining that the betting number counter is greater than or equal to the numerical value “1” (S103-5-1: YES), the main CPU 301 ends the demonstration display command transmission process.

  On the other hand, when it is determined that the betting number counter is not greater than or equal to the numerical value “1” (S103-5-1: NO), the main CPU 301 determines whether or not the non-game time counter has timed up (S103-5). -2). The non-game time counter is timed up when a period during which a player's operation (medal insertion operation, game start operation, etc.) is not accepted becomes longer than a predetermined time length (for example, 1 minute). Specifically, the non-game time counter starts counting when the pre-game start process is started, and is initialized every time the main CPU 301 transmits any command to the sub-control board 400. For example, when a medal is inserted from the medal insertion unit 8 and a insertion command is transmitted, the main CPU 301 initializes a non-game time counter.

  When it is determined that the non-game time counter has timed up (S103-5-2: YES), the main CPU 301 stores a demonstration display command in the command storage area of the main RAM 303 (S103-3), and then the demonstration display command. The transmission process ends. On the other hand, if it is determined that the non-game time counter has not timed up (S103-5-2: NO), the main CPU 301 ends the demo display command transmission process without storing the demo display command. The demonstration display command may be stored at the end of the settlement operation acceptance process.

  FIG. 41 is a flowchart of the internal lottery process. When starting the internal lottery process, the main CPU 301 sets a winning area lottery table (FIGS. 9 to 13) according to the RT gaming state (S106-1). Specifically, the main CPU 301 sets a winning area lottery table according to the RT flag indicating the type of RT gaming state stored in the RT gaming state storage area of the main RAM 303.

  In the internal lottery process, the main CPU 301 acquires the random value R1 stored in the random value R1 storage area (S106-2). The random value R1 is stored in the random value R1 storage area in step 105 (FIG. M-3). Further, the main CPU 301 sets the winning area offset value to the initial value “00” (S106-3). The winning area offset value designates each winning area. The winning area offset value is updated sequentially, and a different winning area is designated each time it is updated. For example, as the winning area offset value, a winning area of “lost” is designated by a numerical value “00”, and a winning area of “normal replay” is designated by a numerical value “12” (see FIGS. 9 to 13).

  The main CPU 301 acquires the lottery value of the winning area designated by the winning area offset value (S106-4). For example, when the winning area lottery table in the RT0 gaming state shown in FIG. 9 is set, if the winning area offset value is “00”, the lottery value “33441” is acquired.

  The main CPU 301 subtracts the lottery value acquired in step S106-4 from the random value R1 acquired in step S106-1 (S106-5). Further, the main CPU 301 determines whether or not the result of subtracting the lottery value from the random value R1 is a negative number (S106-6). For example, in a game in the RT0 gaming state, when a random value R1 having a numerical value “30000” is acquired, a lottery value “33443” is acquired when the winning area offset value is a numerical value “00”, and the result of the subtraction is a negative number. Become. On the other hand, if the acquired random number value R1 is the numerical value “35000”, if the winning area offset value is the numerical value “00”, the result of subtracting the lottery value “33441” from the random number value R1 does not become a negative number.

  When the main CPU 301 determines that the subtraction result is not a negative number (S106-6: NO), the main CPU 301 determines whether or not all winning areas (winning areas “00” to “36”) are designated by the winning area offset value. (S106-7). When the winning area “36” is not designated (S106-7: NO), the main CPU 301 updates the winning area offset value (adds a numerical value “1”) (S106-8), and proceeds to step S106-4. Return processing. For example, when the winning area offset value is “00”, the value is updated to “01”. In step S106-4, the lottery value of the winning area designated by the updated winning area offset value is acquired, and in step S106-5, the lottery value is subtracted from the previous subtraction result. The processing from step S106-4 to step S106-8 is repeated until it is determined that the calculation result is a negative number (S106-6: YES) or all winning areas are designated (S106-7: YES). .

  When it is determined that the calculation result is a negative number or when all the winning areas are designated, the main CPU 301 executes a data storage process (S106-9). Specifically, the main CPU 301 stores the current winning area offset value in the winning area storage area of the main RAM 303. For example, if the winning area offset value with a negative subtraction result is “12”, the numerical value “12” is stored in the winning area storage area. Further, the main CPU 301 stores a winning area command indicating the winning area in the command storage area of the main RAM 303 in the data storing process. In the data storage process, the main CPU 301 stores an RT type command indicating an RT flag stored in the RT gaming state storage area in the command storage area. When the data storage process ends, the main CPU 301 ends the internal lottery process.

  FIG. 42 is a flowchart of the turning effect control process. When the main CPU 301 starts the spinning effect control process, the main CPU 301 acquires a winning area from the winning area storage area (S107-1). Further, the main CPU 301 determines whether or not the winning area acquired from the winning area storage area is “27” (weak watermelon) or “29” (weak cherry) (S107-2). When the main CPU 301 determines that the winning area acquired from the winning area storage area is “27” or “29” (S107-2: YES), the main CPU 301 determines the rotation effect determination table A (see part (a) of FIG. 19). ) Is set (S107-3).

  When it is determined that the winning area acquired from the winning area storage area is not “27” or “29” (S107-2: NO), the main CPU 301 determines that the winning area acquired from the winning area storage area is “28” (strong). It is determined whether it is a watermelon) (S107-4). When it is determined that the winning area acquired from the winning area storage area is “28” (S107-4: YES), the main CPU 301 sets the spinning effect determination table B (see part (b) of FIG. 19). (S107-5).

  When determining that the winning area acquired from the winning area storage area is not “28” (S107-4: NO), the main CPU 301 determines that the winning area acquired from the winning area storage area is “30” (strong cherry) or “ It is determined whether or not it is “31” (weak chance) (S107-6). When the main CPU 301 determines that the winning area acquired from the winning area storage area is “30” or “31” (S107-6: YES), the main CPU 301 determines the rotation effect determination table C (see part (c) of FIG. 19). ) Is set (S107-7).

  When it is determined that the winning area acquired from the winning area storage area is not “30” or “31” (S107-6: NO), the main CPU 301 determines that the winning area acquired from the winning area storage area is “32” (strong) It is determined whether it is a chance) (S107-8). When the main CPU 301 determines that the winning area acquired from the winning area storage area is “32” (S107-8: YES), the main CPU 301 sets the rotation effect determination table D (see part (d) in FIG. 19). (S107-9). On the other hand, if it is determined that the winning area acquired from the winning area storage area is not “32” (S107-8: NO), the main CPU 301 sets the rotation effect number “0” (no effect) in the main RAM 303. It stores in the trunk effect number storage area (S107-10), and the turning effect control process is terminated.

  When the rotation effect determination table A is set at step S107-3, when the rotation effect determination table B is set at step S107-5, the main CPU 301 sets the rotation effect determination table C at step S107-7. When it is set, or when the rotation effect determination table D is set at step S107-9, the rotation effect determination process (S107-11) is executed. In the spinning effect determination process, the main CPU 301 acquires the random value R2 from the random value R2 storage area. Further, the main CPU 301 subtracts each lottery value in the set turning effect determination table from the random effect value R2 in the order of the turning effect number. The effect lottery number in which the result of subtracting the lottery value from the random value R2 becomes a negative number is stored in the spinning effect number storage area.

  The main CPU 301 stores the rotation effect type command indicating the rotation effect number stored in step S107-10 or step S107-11 in the command storage area of the main RAM 303 (S107-12), and ends the rotation effect control process. To do.

  FIG. 43 is a flowchart of wait processing. The main CPU 301 executes the wait process until the execution period of the spinning effect or the wait period for making the unit game time length equal to or longer than a predetermined length elapses.

  When the wait process is started, the main CPU 301 determines whether or not the rotation effect number in the rotation effect number storage area is “0” (S108-1). That is, it is determined whether or not “no effect” has been determined in the rotation effect control process. When the rotation effect number is “0” (S108-1: YES), the main CPU 301 determines whether or not the wait timer is a numerical value “0” (S108-2). The wait timer is decremented every time an interrupt process is executed. When determining that the wait timer has not timed up (wait timer ≠ 0), the main CPU 301 repeats step S108-2 (S108-2: NO).

  On the other hand, when it is determined that the wait timer has timed up (S108-2: YES), the main CPU 301 newly sets the wait timer to an initial value (about 4200 ms) (S108-3). Further, the main CPU 301 stores a reel start command indicating that each reel 12 has started in the command storage area of the main RAM 303 (S108-4), starts rotation of each reel 12, and ends the wait process. To do.

  As understood from the above description, the initial value of the wait timer for which the time-up is determined in step S108-2 in the current game control process is set in step S108-3 of the previous game control process. That is, according to the above configuration, a plurality of game control processes are not executed at intervals of 4.2 seconds or less.

  If the main CPU 301 determines in step S108-1 that the rotation effect number is other than “0”, the main CPU 301 determines whether or not the rotation effect number is a number “1” indicating a short lock effect (S108). -5). When it is determined that the rotation effect number is “1” (S108-5: YES), the main CPU 301 sets a short lock period (1000 sm) in the rotation effect timer (S108-6). In step S108-6, the main CPU 301 sets a short lock drive table (see part (a) of FIG. 20).

  On the other hand, when it is determined that the rotation effect number is not “1” (S108-5: NO), the main CPU 301 determines whether or not the rotation effect number is a number “2” indicating the middle lock effect. (S108-7). When determining that the rotation effect number is “2” (S108-7: YES), the main CPU 301 sets the middle lock period (2000 sm) in the rotation effect timer (S108-8). In step S108-8, the main CPU 301 sets a middle lock drive table (see part (b) of FIG. 20).

  When it is determined that the rotation effect number is not “2” (S108-7: NO), the main CPU 301 determines whether or not the rotation effect number is “3” indicating the long lock effect (S108-). 9). When determining that the rotation effect number is “3” (S108-9: YES), the main CPU 301 sets a long lock period (5000 sm) in the rotation effect timer (S108-10). In step S108-10, the main CPU 301 sets a long lock driving table (see part (c) in FIG. 20).

  When it is determined that the rotation effect number is not “3” (S108-9: NO), the main CPU 301 sets the reverse rotation effect period (25000 sm) in the rotation effect timer (S108-11). In step S108-11, the main CPU 301 sets a reverse rotation drive table (see part (d) in FIG. 20). Note that each spinning effect drive table set in the wait process (S108-6, S108-8, S108-10, S108-11) is referred to in a reel drive control process (S205) of an interrupt process described later.

  When the main CPU 301 sets the rotation effect timer in step S108-6, step S108-8, step S108-10 or S108-11, the main CPU 301 determines whether or not the rotation effect timer has been subtracted to a numerical value “0” ( S108-12). The rotation effect timer is decremented every time the interruption process is executed. When the main CPU 301 repeats step S108-12 until the rotation effect timer expires (that is, until the rotation effect is completed) (S108-12: NO), when determining that the rotation effect timer has expired (S108-12: YES), the process proceeds to step S108-2.

  FIG. 44 is a flowchart of pre-stop processing. When starting the pre-stop process, the main CPU 301 sets an initial value in the acceleration wait timer (S109-1). The initial value of the acceleration weight timer is set to the length of time required for each reel 12 to accelerate to steady rotation. The main CPU 301 determines whether or not the acceleration wait timer has expired (S109-2). The main CPU 301 repeats step S109-2 until the acceleration wait timer expires (S109-2: NO). When the acceleration wait timer expires (S109-2: YES), the main CPU 301 shifts the process to step S109-3. To do.

  In step S109-3, the main CPU 301 stores a numerical value “3” in the non-stop operation counter indicating the number of stop buttons 25 (25L, 25C, 25R) that have not been stopped. Further, the main CPU 301 performs a display combination storage area setting process (S109-4). As described above, each displayable bit in the display combination storing area corresponds to each winning combination, and is a numerical value “1” when there is a possibility that the corresponding winning combination stops on the active line. Accordingly, in step S109-4 in which all the reels 12 are rotating, since all the winning combinations can be stopped on the active line, all the bits in the display combination storing area are set to the numerical value “1”.

  After the display combination storage area setting process, the main CPU 301 proceeds to the priority order storage process (S109-5). FIG. 45 is a conceptual diagram of a plurality of priority storage areas P (PL, PC, PR) set in the priority storage process. As shown in FIG. 45, the priority storage area P includes a left reel priority storage area PL corresponding to the reel 12L, a middle reel priority storage area PC corresponding to the reel 12C, and a right reel priority corresponding to the reel 12R. And a rank storage area PR. Each priority storage area P is divided into a plurality (21) of areas Q. Each area Q corresponds to each symbol position (unit area U) of the reel 12.

  When the priority order storing process is executed, the priority order of the symbols of the area Q is stored in each area Q. For example, the priority “HFF” is stored in the area Q in which a winning combination that has not been won is displayed when the active line is stopped. In addition, the priority “00” is stored in the area Q of the symbol that can be stopped on the active line, and the numerical value “H01” is stored in the area Q of the symbol constituting the winning combination.

  FIG. 46 is a flowchart of the priority order storage process. When starting the priority order storing process, the main CPU 301 stores the non-stop operation counter as the number of searches (S109-5-1). Further, the main CPU 301 determines one reel 12 among the reels 12 that have not been stopped yet as a target reel (S109-5-2).

  The main CPU 301 executes a priority table selection process (S109-5-3). The priority table defines the priority of each winning combination, and one of a plurality of priority tables is selected. For example, a game in which the winning area “push order bell A” (the correct push order is the first stop is the reel 12C) is assumed. According to the priority order table selected in the game, in the middle reel priority order storage area PC, the priority order of the “middle bell” symbol is higher than the priority order of the “upper bell” symbol. On the other hand, in the left reel priority storage area PL and the right reel priority storage area PR, the priority of the “upper bell” symbol is higher than the priority of the “middle bell” symbol. According to the above configuration, by appropriately selecting the priority order table, the symbols to be stopped on the active line change according to the mode of the stop operation order.

  The main CPU 301 stores the initial value “00” in the area pointer and stores the numerical value “21” in the remaining area number (S109-5-4). The area pointer specifies the area Q of the target reel. The remaining area number means the number of areas Q in the target reel where no priority order is stored.

  The main CPU 301 acquires the symbol code (symbol type) of the symbol position designated by the area pointer (S109-5-5). Further, the main CPU 301 determines the priority order according to the symbol code, the winning area (winning role), and the priority order table (S109-5-6). The main CPU 301 stores the determined priority order in the area Q designated by the current area pointer (S109-5-7).

  The main CPU 301 adds a numerical value “1” to the area pointer, and subtracts a numerical value “1” from the remaining area number (S109-5-8). Further, the main CPU 301 determines whether or not the remaining area number is a numerical value “0” (S109-5-9). When determining that the remaining area number is not “0” (S109-5-9: NO), the main CPU 301 repeatedly executes steps S109-5-5 to S109-5-9. On the other hand, when it is determined that the remaining area number is “0” (S109-5-9: YES), that is, when generation of the priority order storage area of the target reel is completed, the main CPU 301 determines “ 1 "is subtracted (S109-5-10).

  After subtracting the number of searches, the main CPU 301 determines whether or not the number of searches has ended (S109-5-11). If it is determined that the number of searches has not ended (S109-5-11: NO), the main CPU 301 returns the process to step S109-5-2, changes the target reel, and proceeds from step S109-5-2 to step S109-5-2. Steps S109-5-11 are repeated. On the other hand, when determining that the number of searches has ended (S109-5-11: YES), the main CPU 301 ends the priority order storage process.

  FIG. 47 is a flowchart of the stop control process. The main CPU 301 determines whether or not the stop button 25 corresponding to the rotating reel 12 has been operated (S110-1). The main CPU 301 repeatedly executes step S110-1 until the stop button 25 corresponding to the rotating reel 12 is operated (S110-1: NO). On the other hand, when the stop button 25 corresponding to the rotating reel 12 is operated (S110-1: YES), the main CPU 301 sends a stop operation command indicating the type of the stop button 25 that has been stopped to a command in the main RAM 303. Store in the storage area (S110-2).

  When the stop operation command is stored, the main CPU 301 updates the stop order storage area (S110-3). Further, the main CPU 301 subtracts the numerical value “1” from the non-stop operation counter (S110-4). The main CPU 301 sets the reel 12 corresponding to the operated stop button 25 as a stop target reel (S110-5).

  The main CPU 301 acquires the current value of the symbol counter (that is, the symbol number located on the middle line) as the stop operation position (S110-6). The main CPU 301 determines the priority order of the area Q of the stop operation position and the area Q for four frames from the next frame of the stop operation position among the areas Q of the priority order storage area of the target reel (that is, for five frames). Is obtained (S110-7). In addition, the main CPU 301 determines the frame with the highest priority among the acquired priorities for the five frames as the planned stop position, and sets the number of frames from the stop operation position to the planned stop position as the number of sliding frames ( S110-8).

  The main CPU 301 updates each bit of the display combination storage area according to the symbol code of the planned stop position (that is, the type of the symbol of the planned stop position) (S110-9). For example, when the reel 12L stops in the stop control process and “Red 7” stops on the active line, the winning combination (for example, “middle bell”) whose left reel symbol is not “Red 7” may win a prize. Therefore, the bit corresponding to the winning combination among the bits of the display combination storing area is a numerical value “0”.

  After updating the display combination storage area, the main CPU 301 determines whether or not the non-stop operation counter is “0” (S110-10). That the non-stop operation counter is a numerical value “0” means that the stop operation has been performed for all the reels 12. When it is determined that the non-stop operation counter is “0” (S110-10: YES), the main CPU 301 ends the stop control process. On the other hand, when it is determined that the non-stop operation counter is not “0” (S110-10: NO), the priority order storage process (see FIG. 46) executed in the pre-stop process is executed (S110-11). Also in step S110-11, the priority is stored in the priority storage area P of the rotating reel 12, as in step S109-3 of the pre-stop process. However, even if the symbols constituting the winning combination shown in the winning area of the winning area storage area, the symbol of the winning combination that is no longer displayed on the active line due to the stop of any reel 12 is The priority is not set higher than other symbols.

  After executing the priority order storage process, the main CPU 301 returns the process to step S110-1. The main CPU 301 repeats the processing from step S110-1 to step 110-11 until a stop operation is performed on all the reels 12, that is, until it is determined that the non-stop operation counter is “0”. Run. When it is determined that the non-stop operation counter is “0” (S110-10: YES), the main CPU 301 ends the reel stop control process.

  FIG. 48 is a flowchart of the display determination process (S111). When the display determination process is started, the main CPU 301 determines whether or not the winning combination stopped on the active line is a winning combination permitted to stop on the active line in the game (S111-1). Specifically, the main CPU 301 compares the display permission bit storage area set according to the winning area of the winning area storage area with the display combination storing area. That is, for the winning combination corresponding to the displayable bit set to “1” among the displayable bits in the display combination storing area in step S111-1, the display permission bit corresponding to the winning combination is “ It is determined whether or not “1” is set. When the display permission bit is set to “0”, the main CPU 301 determines that an illegal winning has occurred.

  When the main CPU 301 determines that an illegal winning has occurred (S111-1: YES), the main CPU 301 stores an illegal winning command, which is a kind of error command, in the command storage area of the main RAM 303 (S111-2), and an illegal winning error process. The game is prohibited from proceeding. When the illegal winning error process is executed, for example, the power button 511 is turned off and then turned on again, and the main CPU 301 is caused to execute the startup process and the setting change process to set a normal set value. It becomes possible to play.

  When it is determined that the winning combination permitted to stop to the active line is stopped (S111-1: NO), the main CPU 301 determines whether or not the re-playing combination is stopped on the active line (S111-). 3). When it is determined that the re-gamer is stopped on the active line (S111-3: YES), the main CPU 301 sets the re-game in-operation flag to the ON state (S111-4), and sets the re-game command as the main. The data is stored in the command storage area of the RAM 303 (S111-5), and the display determination process is terminated. The re-game command indicates that the re-game player is stopped on the active line.

  On the other hand, if it is determined that the re-gamer is not stopped on the active line (S111-3: YES), the main CPU 301 sets the re-game running flag to the OFF state (S111-6), and the winning winning combination Is determined to be stopped on the active line (S111-7). When it is determined that the winning winning combination is stopped on the active line (S111-7: YES), the main CPU 301 stores the winning winning combination command in the command storage area of the main RAM 303 (S111-8). The winning winning combination command indicates the type of winning winning combination aligned with the active line.

  The main CPU 301 adds the number of medals according to the type of the winning combination winning combination stopped on the active line to the credit number (S111-9). After adding the number of credits, the main CPU 301 determines whether or not the result of addition is larger than the numerical value “50” which is the upper limit value of the number of credits (S111-10). When the number of credits is larger than “50” (S111-10: YES), the number of medals exceeding the upper limit of the number of credits (for example, the numerical value “5” when the addition result of step S111-9 is “55”). ") Is set in the medal request counter (S111-11). After setting the number of medals in the medal request counter, the main CPU 301 proceeds to hopper driving processing. On the other hand, when the number of credits is “50” or less (S111-10: NO), the main CPU 301 ends the display determination process.

  If the main CPU 301 determines in step S111-7 that the winning combination has not stopped on the active line (S111-7: NO), the main CPU 301 stores the loss display command in the command storage area of the main RAM 303 (S111-12). ). The lose display command indicates that the winning combination is not stopped on the active line. In the present embodiment, the replay command, the winning winning combination command, and the lose display command are collectively referred to as a display winning combination command.

  FIG. 49 is a flowchart of the hopper driving process. The hopper driving process is executed when the payout request counter is set in the display determination process or the settlement operation acceptance process of the pre-game start process. When the hopper driving process is started, the main CPU 301 stores a payout start command in the command storage area of the main RAM 303 (S120). The payout start command indicates the start of the medal discharge in the hopper 520. Further, the main CPU 301 sets an initial value in the payout period monitoring timer (S121). The payout period monitoring timer expires when a predetermined time length (for example, 30 seconds) has elapsed since the start of the hopper driving process.

  The main CPU 301 starts outputting a hopper drive signal (S122). In the period when the hopper driving signal is output, medals are sequentially discharged from the hopper 520. The main CPU 301 determines whether or not a payout signal from the hopper 520 has been detected (S123). As described above, the payout signal is output from the payout sensor 112SE each time one medal is paid out from the hopper 520. The main CPU 301 repeatedly executes step S123 until it determines that a payout signal has been detected.

  When the main CPU 301 determines that a payout signal has been detected (S123: YES), the main CPU 301 decrements the payout request counter by “1” (S124), and then determines whether or not the payout request counter has been subtracted to a numerical value “0”. Determination is made (S125). When it is determined that the payout request counter has been subtracted to the numerical value “0” (S125: YES), the main CPU 301 stops outputting the hopper drive signal (S126) and stores the payout end command in the command storage area of the main RAM 303. (S127). For example, the sub-control board 400 starts outputting a payout sound effect when receiving a payout start command from the main CPU 301 and stops outputting a payout effect sound when receiving a payout end command. When the main CPU 301 stores the payout end command, the main CPU 301 ends the hopper driving process.

  On the other hand, when determining that the payout request counter is not “0” (S125: NO), the main CPU 301 determines whether or not the payout period monitoring timer is a numerical value “0” (S128). When it is determined that the payout period monitoring timer is not the numerical value “0” (S128: NO), the main CPU 301 repeatedly executes steps S123 to S125. On the other hand, when it is determined that the payout period monitoring timer is a numerical value “0” (S128: YES), the main CPU 301 sets an error command (S129), and shifts the processing to hopper empty error processing. That is, if the discharge of the number of medals of the payout request counter is not completed between the start of the hopper driving process and the payout period monitoring timer, the main CPU 301 executes the hopper empty error process and the progress of the game Is prohibited. When the hopper empty process is executed, for example, when the hopper 520 is replenished with medals and the reset button 512 is operated, the progress of the game is permitted.

  FIG. 50 is a flowchart of the RT gaming state transition process. In the RT gaming state transition process, the main CPU 301 changes the RT gaming state according to the combination of symbols stopped on the active line.

  When starting the RT gaming state transition process, the main CPU 301 determines whether or not the RT1 transition symbol (see FIG. 16) has stopped on the winning line (S113-1). As described above, the RT1 transition symbol stops at the active line when the winning combination “upper bell” is missed (see FIG. 17). When it is determined that the RT1 transition symbol has stopped on the winning line (S113-1: YES), the main CPU 301 changes the RT gaming state to the RT1 gaming state (S113-2). Specifically, the RT flag stored in the RT gaming state storage area of the main RAM 303 is changed to “RT1”. In the RT1 gaming state, when the RT1 transition symbol stops on the winning line, the RT gaming state is not changed. When the RT flag is changed, the main CPU 301 stores an RT1 transition command indicating that the RT1 transition symbol has stopped on the active line in the command storage area (S113-3), and ends the RT gaming state transition process.

  When the main CPU 301 determines that the RT1 transition symbol has not stopped on the winning line (S113-1: NO), the main CPU 301 determines whether or not the RT2 transition symbol has stopped on the active line (S113-4). As described above, the RT2 transition symbol (RT2 transition replay) is stopped on the active line when each stop button 25 is operated in a predetermined stop operation order (correct answer push order) in the game in which RT1 push order replay is won. To do.

  When it is determined that the RT2 transition symbol has stopped on the winning line (S113-4: YES), the main CPU 301 changes the RT gaming state to the RT2 gaming state (S113-5). Specifically, the RT flag stored in the RT gaming state storage area of the main RAM 303 is changed to “RT2”. When the main CPU 301 changes the RT flag, it stores an RT2 transition command indicating that the RT2 transition symbol has stopped on the active line in the command storage area (S113-6), and ends the RT gaming state transition process.

  When the main CPU 301 determines that the RT2 transition symbol has not stopped on the winning line (S113-4: NO), the main CPU 301 determines whether or not the RT3 transition symbol has stopped on the active line (S113-7). As described above, the RT3 transition symbol (RT3 transition replay) is selected when the RT2 push order replay is stopped in a predetermined stop operation order (correct push order) or a special game falling replay is won. In the played game, stop at the active line.

  When it is determined that the RT3 transition symbol has stopped on the winning line (S113-7: YES), the main CPU 301 changes the RT gaming state to the RT3 gaming state (S113-8). Specifically, the RT flag stored in the RT gaming state storage area of the main RAM 303 is changed to “RT3”. When the main CPU 301 changes the RT flag, it stores an RT3 transition command indicating that the RT3 transition symbol has stopped on the active line in the command storage area (S113-9), and ends the RT gaming state transition process.

  When determining that the RT3 transition symbol has not stopped on the winning line (S113-7: NO), the main CPU 301 determines whether the RT4 transition symbol has stopped on the active line (S113-10). As described above, the RT4 transition symbol (RT4 transition replay and 7-match replay) is stopped on the active line when the RT3 push order replay is stopped in a predetermined stop operation order (correct push order) in the winning game. To do.

  When it is determined that the RT4 transition symbol has stopped on the winning line (S113-10: YES), the main CPU 301 changes the RT gaming state to the RT4 gaming state (S113-11). Specifically, the RT flag stored in the RT gaming state storage area of the main RAM 303 is changed to “RT4”. If the RT4 transition symbol stops on the winning line in the RT4 gaming state, the RT gaming state is not changed. That is, in the RT4 gaming state, the RT4 gaming state is maintained regardless of the stop operation order as long as the 7-piece replay is won. On the other hand, when the special game falling replay is won, the RT3 transition symbol stops on the active line and transitions to the RT3 gaming state (falls) regardless of the stop operation order. When the RT flag is changed, the main CPU 301 stores an RT4 transition command indicating that the RT4 transition symbol has stopped on the active line in the command storage area (S113-9), and ends the RT gaming state transition process.

  FIG. 51 is a flowchart of the interrupt process. As described above, the main CPU 301 executes an interrupt process every 1.49 ms during the period when the game control process is being executed.

  When starting the interrupt process, the main CPU 301 saves the state of various registers (S201). For example, the number of steps S of the game control process that was executed when the interrupt process was started is saved.

  The main CPU 301 executes an input port reading process (S202) for reading signals from various sensors via the I / F circuit 305. Specifically, the main CPU 301 reads ON signals from the start switch 24SW, each stop switch 25SW, the medal sensor 34SE, the settlement switch 23SW, and the like in the input port reading process. When the ON signal from each sensor (switch) is read, the main CPU 301 sets the detection flag of the sensor that has read the ON signal to the ON state. The main CPU 301 determines the presence / absence of an ON signal of each sensor (switch) from the state of each detection flag in each step S of the game control process.

  The main CPU 301 executes timer measurement processing (S203) for subtracting the values of various timers. For example, the main CPU 301 subtracts the payout period monitoring timer set in the hopper driving process of the game control process in the timer measurement process. Further, in the timer measurement process, subtraction of the rotation effect timer and the wait timer is executed.

  The main CPU 301 selects one of the rotating reels as a drive target reel (S204), and executes a stepping motor drive control process (S205) for the drive target reel. Specifically, the main CPU 301 determines whether or not it is the switching timing of the excitation pattern of the stepping motor of the selected reel 12, and when it is the switching timing, it outputs a drive pulse to the stepping motor to generate the excitation pattern. Switch. Each time the interrupt process is executed, the excitation pattern of the stepping motor is switched at an appropriate timing, whereby each reel 12 rotates at an appropriate speed.

  In addition, when the rotation effect drive table is set, the stepping motor is driven according to the set rotation effect drive table. Specifically, the main CPU 301 determines whether or not the number of interrupts specified in the spinning drum effect driving table has been reached in the current interrupt process. When the number of interruptions has been reached, the main CPU 301 supplies a driving pulse for rotating each reel 12 in the direction specified by the rotation direction of the rotation effect driving table to each stepping motor 101.

  The main CPU 301 determines whether or not the drive control processing for all the reels 12 has been executed (S206). When it is determined that the drive control processing for all the reels 12 has not been executed (S206: NO), the main CPU 301 repeats step S204 and step S205. On the other hand, when it is determined that the drive control process for all the reels 12 has been executed (S206: YES), the main CPU 301 shifts the process to an external signal output process (S207).

  In the external signal output process, a predetermined signal is output to the outside of the gaming machine 1. For example, when the setting change process is started, the main CPU 301 outputs a signal indicating the start of the setting change process to the outside of the gaming machine 1. The signal output from the gaming machine 1 is output to the outside through, for example, a dedicated board.

  The main CPU 301 drives various lamps in the LED display process (S208). For example, the main CPU 301 displays the BET lamp 14 in a mode indicated by the BET lamp display data generated by the game control process, and turns on the re-game display lamp 18 when the re-game operating flag is set to the ON state. Then, the number of credits is displayed on the stored number display 17.

  The main CPU 301 transmits the command stored in the command storage area of the main RAM 303 to the sub control board 400 in the control command transmission process (S209). In the command storage area, for example, various commands stored in the game control process are stored.

  The main CPU 301 executes a register restoration process (S210), and restores the contents of the register saved in step S210. When the register return process is executed, the main CPU 301 returns the process to step S of the game control process that was executed when the interrupt process was started.

<Each process executed by the sub CPU>
FIG. 52 is a flowchart of sub activation processing of the sub CPU 412. The sub CPU 412 executes a sub activation process when a reset signal is input from a reset circuit (not shown). The reset circuit outputs a reset signal when the power supply voltage supplied to the sub-control board 400 exceeds a predetermined threshold. That is, for example, when the supply of power supply voltage to the sub control board 400 is started by operating the power switch SW, the sub activation process is executed.

  When the sub activation process is started, the sub CPU 412 executes an activation initialization process (S301). In the sub activation process, various registers of the sub control board 400 are initialized, and initial values are set in various counters of the sub RAM 414.

  In the sub activation process, the sub CPU 412 determines whether there is a backup abnormality in the sub RAM 414. If the backup is abnormal, the sub CPU 412 initializes the backup data. Further, the sub CPU 412 determines whether or not the data stored in various ROMs including the CGROM 424 is appropriate in the startup initialization process. For example, data stored at a specific address in each ROM is read to determine whether or not the data is appropriate. When an abnormality is found in various ROMs, the sub CPU 412 shifts to predetermined error processing.

  In the sub activation process, the sub CPU 412 activates the lamp control task (S302), activates the acoustic control task (S303), activates the image control board communication task (S304), activates the main control board communication task (S305), and effects. The button input task is activated (S306). The sub CPU 412 controls various lamps including the side lamp 5 and the effect lamp 28 by a lamp control task. Further, the sub CPU 412 controls the speakers (31, 32) by an acoustic control task. Further, the sub CPU 412 transmits a command to the image control board 420 by the image control board communication task, receives a command from the main control board 300 in the main control board communication task, and performs the effect button 26 and the direction in the effect button input task. The operation of the designation button 27 is accepted.

  A timer interrupt signal is input to the sub CPU 412 at predetermined time intervals. When receiving the timer interrupt signal, the sub CPU 412 executes one of the tasks. That is, each peripheral device including various lamps and speakers (31, 32) is controlled in a time division manner.

  FIG. 53 is a flowchart of a lamp control task. When starting the lamp control task, the sub CPU 412 initializes data for controlling various lamps (S302-1). When the sub CPU 412 initializes various data, the sub CPU 412 shifts the processing to the lamp data analysis processing (S302-2). The lamp data is data indicating blinking patterns of various lamps. For example, a time series (300 ms lighting → 300 ms lighting → 300 ms lighting →...) Of data indicating the time for turning on a specific lamp and data indicating the time for turning off a specific lamp is suitably employed as the lamp data.

  In the lamp control process (S302-3), the sub CPU 412 blinks a specific lamp in a manner specified by the lamp data. The lamp data analysis process and the lamp effect execution process are repeatedly executed until a timer interrupt signal is input.

  FIG. 54 is a flowchart of the acoustic control task. When starting the acoustic control task, the sub CPU 412 initializes various data for controlling the speakers (31, 32) (S303-1). When the sub CPU 412 initializes various data, the sub CPU 412 shifts the processing to acoustic analysis processing (S303-2).

  In the sound control process (S303-3), the sub CPU 412 instructs the sound board 430 (the sound source IC 431) according to the result of the sound data analysis process. The sound source IC 431 reads out sound data from the sound source ROM 432 in accordance with an instruction from the sub CPU 412, generates an sound signal from the sound data, and supplies the sound signal to the speakers (31, 32). The acoustic data analysis process and the sound effect execution process are repeatedly executed until a timer interrupt signal is input.

  FIG. 55 is a flowchart of the image control board communication process. When the sub CPU 412 starts the image control board communication task, the sub CPU 412 sets an effect command according to the effect number stored in the sub RAM 414 (S305-1). The effect number indicates the type of effect executed in the gaming machine 1, and is stored in the effect number storage area of the sub RAM 414 in the effect lottery process described later. The sub CPU 412 transmits the effect command set in step S305-1 to the image control board 420 (S305-2), and ends the image control board communication task. The image control board communication task may receive a command from the image control board 420.

  FIG. 56 is a flowchart of the main control board communication task. When the main control board communication task is started, the sub CPU 412 executes pre-communication start processing (S306-1) for clearing stored commands and the like. After executing the pre-communication start process, the sub CPU 412 proceeds to a received command check process (S306-2). In the received command check process, the content of the command received from the main control board 300 is checked.

  The sub CPU 412 determines whether the command checked in the current received command check process is different from the command checked in the previous received command check process (S306-3). That is, in step S306-3, the sub CPU 412 determines whether or not the command from the main control board 300 has changed. The sub CPU 412 repeatedly executes step S306-3 until the command from the main control board 300 changes (S306-3: NO). When the content of the command from the main control board 300 changes (S306-3: YES), the sub CPU 412 shifts the process to a command analysis process (S306-4).

  After executing the command analysis process, the sub CPU 412 executes a game information update process (S306-5). In the game information update process, the sub CPU 412 updates the game information according to the command received from the main control board 300. The game information is various information including a game counter, for example. In step S306-5, the sub CPU 412 executes one of a plurality of types of game information update processing. Specifically, the sub CPU 412 executes a game information update process corresponding to the type of command received from the main control board 300 among a plurality of types of game information update processes. For example, when receiving the start operation command, the sub CPU 412 executes a game information update process for updating the game number counter. After updating the game information, the sub CPU 412 returns the process to step S306-2, and repeats the processes from step S306-2 to step S306-5 until the next timer interrupt signal is input.

  FIG. 57 is a flowchart of command analysis processing. When starting the command analysis process, the sub CPU 412 executes an effect content determination process (S401). As will be described later, the sub CPU 412 determines the content of the effect (notification) to be executed by the gaming machine 1 in the effect content determination process.

  The sub CPU 412 determines lamp data according to the effect determined in the effect content determination process (S402), and stores the determined lamp data in the sub RAM 414 (S403). Further, the sub CPU 412 determines acoustic data according to the effect determined in the effect content determination process (S404), and stores the determined acoustic data in the sub RAM 414 (S405). When the acoustic data is stored, the sub CPU 412 ends the command analysis process.

  FIG. 58 is a flowchart of the effect content determination process. When starting the effect content determination process, the sub CPU 412 determines whether or not the command received from the main control board 300 is a setting change start command or a setting value command (S401-1). If it is determined that the command received from the main control board 300 is a setting change start command or a setting value command (S401-1: YES), the sub CPU 412 shifts the processing to the setting change start / end processing (S401-2). To do.

  When the setting change start command is received, the sub CPU 412 executes setting change start / end processing. Specifically, the sub CPU 412 notifies that the setting change process is being executed in the setting change start / end process. For example, the sub CPU 412 displays a message “setting is being changed” on the liquid crystal display device 30, and outputs the sound of the message from each speaker. If it is determined that the set value command has been received (that is, when the setting change process has ended), the sub CPU 412 stores the set value indicated by the set value command in the sub RAM 414 and ends the notification of the setting change process. . After executing the setting change start / end process, the sub CPU 412 ends the effect content determination process.

  If it is determined that the command received from the main control board 300 is not a setting change start command or a setting value command (S401-1: NO), the sub CPU 412 determines whether a demonstration display command has been received (S401-). 3). If it is determined that a demo display command has been received (S401-3: YES), the sub CPU 412 proceeds to a process for receiving a demo display command (S401-4). In the process of receiving the demonstration display command, the sub CPU 412 displays a demonstration screen on the liquid crystal display device 30 and turns on the demonstration status flag of the sub RAM 414. After executing the demonstration display command reception process, the sub CPU 412 ends the effect content determination process.

  If it is determined that the received command is not a demonstration display command (S401-3: NO), the sub CPU 412 receives an insertion-related command (medal automatic insertion command, medal insertion command, 1 BET operation command, MAX-BET operation command). It is determined whether or not (S401-5). When it is determined that the input related command has been received (S401-5: YES), the sub CPU 412 shifts the processing to the input related command reception process (S401-6). In the insertion-related command reception process, the sub CPU 412 generates an effect when a medal is inserted, for example. After executing the process related to receiving the insertion-related command, the sub CPU 412 ends the effect content determination process.

  When the sub CPU 412 determines that the received command is not an input-related command (S401-5: NO), the sub CPU 412 determines whether a settlement operation command has been received (S401-7). If it is determined that a settlement operation command has been received (S401-7: YES), the sub CPU 412 executes a settlement operation command reception process (S401-8). In the settlement operation command reception process, the sub CPU 412 notifies that the medal settlement is being executed. The sub CPU 412 displays, for example, a message “Checkout in progress” on the liquid crystal display device 30 and outputs a predetermined warning sound from the speaker in the process at the time of payment operation command reception. After executing the settlement operation command reception process, the sub CPU 412 ends the effect content determination process.

  When the sub CPU 412 determines that the received command is not a settlement operation command (S401-7: NO), the sub CPU 412 determines whether a start operation command has been received (S401-9). If it is determined that the start operation command has been received (S401-9: YES), the sub CPU 412 executes a start operation time process (S401-10). In the start operation process, the sub CPU 412 executes various processes including an effect lottery process and an ART lottery process. After executing the start operation process, the sub CPU 412 ends the effect content determination process.

  When the sub CPU 412 determines that the received command is not a start operation command (S401-9: NO), the sub CPU 412 determines whether a reel start command has been received (S401-11). If it is determined that a reel start command has been received (S401-11: YES), the sub CPU 412 executes a reel start command reception process (S401-12). In the reel start command reception process, the sub CPU 412 outputs, for example, a reel rotation sound output when the rotation of the reel is started from the speaker. After executing the reel start command reception process, the sub CPU 412 ends the effect content determination process.

  When determining that the received command is not a reel start command (S401-11: NO), the sub CPU 412 determines whether a stop operation command has been received (S401-13). When it is determined that the stop operation command has been received (S401-13: YES), the sub CPU 412 executes a stop operation time process (S401-14). In the stop operation process, for example, an effect is generated when the operation of the stop button 25 is triggered. After executing the stop operation process, the sub CPU 412 ends the effect content determination process.

  If the sub CPU 412 determines that the received command is not a stop operation acceptance command (S401-13: NO), whether or not a display winning combination command (replay command, winning winning combination command or lost display command) has been received. Is determined (S401-15). When it is determined that the display winning combination command has been received (S401-15: YES), the sub CPU 412 executes a display winning combination command reception process (S401-16). In the display winning combination command reception process, the sub CPU 412 shifts the effect state.

  In addition, the sub CPU 412 executes an effect that notifies the transition of the effect state. For example, the sub CPU 412 subtracts the numerical value “1” from the ART set counter and displays the message “ART START!” On the liquid crystal display device 30 when the RT3 transition symbol stops at the valid line in the ART start preparation state. . Further, the sub CPU 412 adds a numerical value “50” to the ART counter. For example, when the ART counter is decremented to a numerical value “0” in the ART state, the sub CPU 412 shifts the effect state to the ART end preparation state. After executing the display winning combination command reception process, the sub CPU 412 ends the effect content determination process.

  When the sub CPU 412 determines that the received command is not a display winning combination command (S401-15: NO), the sub CPU 412 determines whether a payout start command or a payout end command has been received (S401-17). If it is determined that a payout start command or a payout end command has been received (S401-17: YES), the sub CPU 412 executes a payout sound control process (S401-18). For example, when receiving a payout start command, the sub CPU 412 starts outputting a medal payout sound for notifying medal discharge. When the payout end command is received, the sub CPU 412 stops the medal payout sound. After executing the payout sound control process, the sub CPU 412 ends the effect content determination process.

  If it is determined that the received command is not a payout start command or a payout end command (S401-17: NO), the sub CPU 412 determines whether an error command (such as an illegal winning command) has been received (S401-19). ). When determining that the error command has not been received (S401-19: NO), the sub CPU 412 ends the effect content determination process. On the other hand, if it is determined that an error command has been received (S401-19: YES), the sub CPU 412 executes an error notification process (S401-20). In the error notification process, the sub CPU 412 displays, for example, the type of error indicated by the received error command on the liquid crystal display device 30. After executing the error notification process, the sub CPU 412 ends the effect content determination process.

  FIG. 59 is a flowchart of the start operation time process. When the sub CPU 412 starts the start operation process, the sub CPU 412 acquires the effect state from the effect state storage area of the sub RAM 414 (S501). Thereafter, the sub CPU 412 determines whether or not the effect state acquired in step S501 is a normal effect state, an ART start preparation state, or an ART end preparation state (S502).

  When it is determined that the performance state is the normal performance state, the ART start preparation state, or the ART end preparation state (S502: YES), the sub CPU 412 proceeds to the ART lottery process (S503), and then proceeds to the mode transition lottery process. (S504). On the other hand, when it is determined that the effect state is not the normal effect state, the ART start preparation state, or the ART end preparation state (S502: NO), the sub CPU 412 determines whether or not it is the ART state (S505).

  When it is determined that the performance state is the ART state (S505: YES), the sub CPU 412 shifts to a specialized game lottery process (S506), and then shifts to an extra lottery process (S507). On the other hand, when it is determined that the state is not the ART state (S505: NO), that is, when the production state is the specialized game state, the sub CPU 412 proceeds to the extra lottery process (S508).

  As understood from FIG. 59, after executing step S504, step S507, or step S508, the sub CPU 412 executes an effect lottery process (S509).

  FIG. 60 is a flowchart of the ART lottery process. When the ART lottery process is started, the sub CPU 412 determines whether or not the winning area determined by the internal lottery process of the main CPU 301 is an ART lottery (winning areas “26” to “32”) (S503-1). ). When determining that it is not an ART lottery role (S503-1: NO), the sub CPU 412 ends the ART lottery process.

  On the other hand, if it is determined that it is an ART lottery (S503-1: YES), the sub CPU 412 acquires a random number value R4 (S503-2) and stores the ART lottery stored in the ART lottery mode storage area of the sub RAM 414. The ART lottery table (FIG. 24) is set according to the mode (S503-3). Further, the sub CPU 412 subtracts the lottery value corresponding to the winning area among the lottery values in the ART lottery table to the random value R4 (S503-4). The sub CPU 412 determines whether or not the result of subtracting the lottery value from the random value R4 is a negative number (S503-5). If the result of subtracting the lottery value from the random value R4 is not a negative number (S503-5: NO), the sub CPU 412 ends the ART lottery process.

  If the result of subtracting the lottery value from the random number value R4 is a negative number (S503-5: YES), the sub CPU 412 adds the ART set counter of the sub RAM 414 (S503-6). In this embodiment, every time the transition to the ART state is determined, the ART set counter is incremented by “1”, but the numerical value added to the ART set counter can be set as appropriate. For example, a configuration in which a numerical value added to the ART set counter is determined by lottery is suitably employed. After adding the ART set counter, the sub CPU 412 ends the ART lottery process.

  FIG. 61 is a flowchart of the mode transition lottery process. When the sub CPU 412 starts the mode transition lottery process, the sub CPU 412 acquires a random value R5 (S504-1), and determines whether or not the current ART lottery mode is the low probability mode (S504-2). When it is determined that the ART lottery mode is the low probability mode (S504-2: YES), the sub CPU 412 determines whether the winning area determined by the main CPU 301 is the mode transition lottery (winning areas “18” to “32”). It is determined whether or not (S504-3). If it is determined that none of the mode transition lottery roles (S504-3: NO), the sub CPU 412 ends the mode transition lottery process.

  On the other hand, when it is determined that one of the mode transfer lottery winnings has been won (S504-3: YES), the sub CPU 412 refers to the ART lottery mode transfer table (FIG. 25) and responds according to the type of mode transfer lottery winning combination. The lottery value is acquired, and the lottery value is subtracted from the random value R5 (S504-4). The sub CPU 412 determines whether or not the result of subtracting the lottery value from the random value R5 is a negative number (S504-5). When it is determined that the subtraction result is a negative number (S504-5: YES), the sub CPU 412 changes the ART lottery mode to the high probability mode (S504-6), and ends the mode transition lottery process. On the other hand, when it is determined that the subtraction result is not a negative number (S504-5: NO), the sub CPU 412 ends the mode transition lottery process without changing the ART lottery mode.

  If it is determined in step S504-3 that the current ART lottery mode is not the low probability mode (S502-2: NO), the sub CPU 412 determines that the winning area determined by the main CPU 301 is from “00” to “17”. It is determined whether or not any of them (S504-7). When determining that the winning area is not “00” to “17” (S504-7: NO), the sub CPU 412 ends the mode transition lottery process. On the other hand, when it is determined that the winning area is any one of “00” to “17” (S504-7: YES), the sub CPU 412 subtracts a predetermined lottery value (numerical value “3278”) from the random value R5. (S504-8). The sub CPU 412 determines whether or not the result of subtracting the lottery value from the random value R5 is a negative number (S504-9). If it is determined that the subtraction result is a negative number (S504-9: YES), the sub CPU 412 changes the ART lottery mode to the low probability mode (S504-10), and ends the mode transition process. On the other hand, if it is determined that the subtraction result is not a negative number (S504-9: NO), the sub CPU 412 ends the mode transition lottery process without changing the ART lottery mode.

  FIG. 62 is a flowchart of the extra lottery process in the ART state. The sub CPU 412 acquires the random value R7 when starting the extra lottery process (S507-1). Further, the sub CPU 412 determines whether or not the winning area determined by the main CPU 301 is any one of “27” to “32” (S507-2). When determining that the winning area is not “27” to “32” (S507-2: NO), the sub CPU 412 finishes the extra lottery process.

  When it is determined that the winning area is any one of “27” to “32” (S507-2: YES), the sub CPU 412 refers to the extra lottery table (FIG. 28) and determines the lottery value corresponding to the winning area. The lottery value is acquired and subtracted from the random value R5 (S507-3). Specifically, when the added game number is sequentially subtracted from the lottery value of “0 game” to the random number value R7 and the subtraction result becomes a negative number, step S507-3 is ended. Thereafter, the sub CPU 412 adds the number of added games whose subtraction result is negative in step S507-3 to the ART counter of the sub RAM 414 (S507-4), and finishes the adding lottery process.

  FIG. 63 is a flowchart of the extra lottery process for the special gaming state. The sub CPU 412 acquires the random value R7 when starting the extra lottery process (S508-1). Further, the sub CPU 412 determines whether or not the winning area determined by the main CPU 301 is “00” or “18” to “32” (S508-2). When it is determined that the winning area is not “18” to “32” (S508-2: NO), the sub CPU 412 finishes the extra lottery process.

  On the other hand, if it is determined that the winning area is any of “18” to “32” (S508-2: YES), the sub CPU 412 refers to the extra lottery table (FIG. 29) and responds to the winning area. A lottery value is acquired, and the lottery value is subtracted from the random value R5 (S508-3). Specifically, when the added game number is sequentially subtracted from the lottery value of “0 game” to the random number value R7 and the subtraction result becomes a negative number, step S508-3 is terminated. Thereafter, the sub CPU 412 adds the number of added games whose subtraction result is negative in step S508-3 to the ART counter of the sub RAM 414 (S508-4), and finishes the adding lottery process.

  FIG. 64 is a flowchart of the effect lottery process. When starting the effect lottery process, the sub CPU 412 acquires the random value R3 (S509-1). Further, the sub CPU 412 sets the effect lottery table (FIG. 23) according to the current effect state, the winning area determined by the main CPU 301 and the spinning effect number (S509-2). The sub CPU 412 sequentially acquires lottery values corresponding to the respective effects with reference to the set effect lottery table, and subtracts the acquired lottery values from the random value R3 (S509-3). When the subtraction result becomes a negative number, the sub CPU 412 stores the effect number whose subtraction result is a negative number in the effect number storage area of the sub RAM 414 (S509-4).

  The sub CPU 412 sets the effect button instruction flag to the ON state according to the effect number (S509-5). Specifically, when the production number for which the production button operation instruction is executed is determined among the production numbers, the sub CPU 412 sets the production button instruction flag to the ON state. In a game in which an effect button operation instruction is executed, for example, a message “PUSH!” Is displayed on the liquid crystal display device 30. When the effect button 26 is operated during the period in which the effect button operation instruction is executed, the sub CPU 412 causes a predetermined effect to be executed. After executing Step S509-5, the sub CPU 412 ends the effect lottery process.

  The description of the command analysis process (step S306-4 in FIG. 56) of the main control board communication task is as described above. Hereinafter, the game information update process (S306-5) will be described with reference to FIG. FIG. 65 is a flowchart of the game information update process executed when the start operation command is received in the game information update process.

  When the game information update process is started, the sub CPU 412 acquires the current value of the monitoring timer (S601). The monitoring timer is stored in the sub RAM 414 and is subtracted at a predetermined time interval. After acquiring the current value of the monitoring timer, the sub CPU 412 determines whether or not the current value of the monitoring timer acquired in step S601 has been subtracted from the numerical value “0” (S602). When determining that the current value of the monitoring timer has been subtracted to the numerical value “0” (S602: YES), the sub CPU 412 resets the monitoring timer to the initial value (S603). The initial value of the monitoring timer is a numerical value “M”. The monitoring timer expires when approximately 2000 ms elapses after being reset to the initial value. That is, the numerical value “M” is subtracted to the numerical value “0” in about 2000 ms.

  As described above, since the game information update process of FIG. 65 is executed every time a start operation command is received, the monitoring timer is reset to the initial value “M” every time a start operation command is received. Therefore, when the time interval from the time when the previous start operation command is received to the time when the current start operation command is received is 2000 ms or more, the monitoring timer is set to the time when the current start operation command is received. Is up. On the other hand, if the time interval from the time when the previous start operation command is received to the time when the current start operation command is received is shorter than 2000 ms, the monitoring timer is set to the time when the current start operation command is received. Not up. In the present embodiment, for the sake of explanation, a period from the time when the previous start operation command is received to the time when the current start operation command is received is referred to as a reception interval TX. A period from when the monitoring timer is reset to the initial value until the time is up is referred to as a monitoring period TY.

  As will be described in detail later, when a player plays a game, a period longer than the monitoring period TY is usually required from the operation of the start lever 24 in the current game to the operation of the start lever 24 in the next game. is there. Therefore, in principle, no start operation command is received in the monitoring period TY. For example, when a plurality of unauthorized commands are transmitted from the unauthorized board at a time interval shorter than the monitoring period TY, each unauthorized command is received in the monitoring period TY. In the present embodiment, the start operation command received during the monitoring period TY is detected as an illegal command.

  If it is determined in step S602 that the monitoring timer has not expired (S602: NO), the sub CPU 412 adds an abnormal reception counter (S604), and then the abnormal reception counter is a numerical value “N” (N is 1). It is determined whether or not it is greater than or equal to the above integer (S605). If it is determined that the abnormal reception counter is greater than or equal to the numerical value “N” (S605: YES), the sub CPU 412 proceeds to error processing. In error processing, for example, reception of a command from the main control board 300 is stopped. Moreover, when each command (for example, start operation command) transmitted by each game is received in the execution period of an error process, it is good also as a structure which does not perform the process according to the said command. In step S605, when the sub CPU 412 determines that the abnormal reception counter is not greater than or equal to the numerical value “N” (S605: NO), the process proceeds to step S603.

  After resetting the monitoring timer to the initial value, the sub CPU 412 determines whether the current performance state is a normal low probability state, a normal high probability state, or a fake state (S606). If it is determined that the performance state is not one of the normal low probability state, the normal high probability state, or the fake state (S606: NO), the sub CPU 412 ends the game information update process. On the other hand, if it is determined that the performance state is one of the normal low probability state, the normal high probability state, or the fake state (S606: YES), the sub CPU 412 subtracts the game counter (S607). Also, after subtracting the game counter, the sub CPU 412 determines whether or not the game counter is a numerical value “0” (S608). When it is determined that the game counter is not the numerical value “0” (S608: NO), the sub CPU 412 ends the game information update process.

  On the other hand, when it is determined that the game counter is a numerical value “0” (S608: YES), the sub CPU 412 adds the ART set counter (S609). Further, the sub CPU 412 sets the effect state to the ART latent state (S610), and ends the game information update process. That is, when the game counter (game information) is updated to a numerical value “0”, the sub CPU 412 grants the right (privilege) to shift the effect state to the ART state.

  FIG. 66 is a time chart for explaining a specific example of the operation of the sub CPU 412. FIG. 66 shows the time when the start operation command is received, the value of the monitoring timer at each time, and the value of the abnormal reception counter at each time.

  Part (a) of FIG. 66 is a specific example when a start operation command is received after the monitoring period TY has elapsed. As shown in part (a) of FIG. 66, when the start operation command Com1 is received (SA1), the current value “0” of the monitoring timer is acquired (SA2). When the start operation command Com1 is received, the monitoring timer is reset to the initial value (SA3), and the monitoring period TY1 starts. When about 2000 ms elapses after the monitoring timer is reset, the monitoring timer expires (SA5) and the monitoring period TY1 ends. Since the monitoring timer when the start operation command Com1 is received is the numerical value “0”, the abnormal reception counter is not added (SA4).

  When the start operation command Com2 is received after the monitoring timer expires (SA6), the current value “0” of the monitoring timer is acquired (SA7). When the start operation command Com2 is received, the monitoring timer is reset to the initial value (SA8), and the monitoring period TY2 is started. Since the monitoring timer when the start operation command Com2 is received is the numerical value “0”, the abnormal reception counter is not added (SA9). As understood from the above description, when the start operation command (Com2) is received after the monitoring period TY (TY1) has elapsed, the abnormal reception counter is not added (maintained by the numerical value “0”).

  Part (b) of FIG. 66 is a specific example when a start operation command is received during the monitoring period TY. In the specific example of part (b) of FIG. 66, error processing is executed when the abnormal reception counter is a numerical value “N” larger than the numerical value “2”, but the numerical value “N” It is not limited to numerical values.

  As shown in part (b) of FIG. 66, when the start operation command Com1 is received (SB1), the current value “x” (M> x> 0) of the monitoring timer is acquired (SB2). When the start operation command Com1 is received, the monitoring timer is reset to the initial value (SB3), and the monitoring period TY1 starts. Since the monitoring timer value “x” at the time when the start operation command Com1 is received is not “0”, an abnormal reception counter is added (SB4).

  As shown in part (b) of FIG. 66, when the start operation command Com2 is received before the monitoring period TY1 ends (SB5), the current value “y” (M> y> 0) of the monitoring timer is acquired. (SB6). When the start operation command Com2 is received, the monitoring timer is reset to the initial value (SB7), and the monitoring period TY2 starts. Since the numerical value “y” of the monitoring timer at the time when the start operation command Com2 is received is not “0”, an abnormal reception counter is added (SB8). Thereafter, when the total number of start operation commands received in the monitoring period TY reaches “N”, error processing is executed (SB8).

  As can be understood from the above description, the sub CPU 412 of the present embodiment has a time point (2000 ms) after a predetermined time (2000 ms) has elapsed from the time point when the start operation command is received (the start time point of the reception interval TX1 and the monitoring period TY1). When the reception time of the next start operation command (end time of the reception interval T1X) is located after the end of the monitoring period TY1, the game counter is subtracted. On the other hand, when the reception time point of the next start operation command is located before the time point when the predetermined time has elapsed from the time point when the start operation command is received, the abnormal reception counter is added. In other words, the sub CPU 412 of this embodiment also monitors the reception interval TX of the start operation command.

  According to the above configuration, a command received during the monitoring period TY is detected as an illegal command, and error processing is executed when an illegal command is detected a predetermined number of times (N times). Therefore, according to the configuration of the present embodiment, fraudulent acts are suppressed.

  FIG. 67 is a system sequence diagram for explaining the operation of the gaming machine 1. In FIG. 67, each operation (Sa1 to Sa3) of the player in the G-th game (G is a natural number) and each process (Sb1) executed by the main control board 300 (main CPU 301) according to the player's operation To Sb8).

  When starting the game, the player operates the start lever 24 (Sa1). When the start lever 24 is operated, the main control board 300 transmits a start operation command to the sub control board 400 (Sb1). When the sub control board 400 receives the start operation command, the monitoring period TY is started.

  After transmitting the start operation command, the main control board 300 starts the wait process (Sb2). Further, when the wait timer expires after the wait process is started, the main control board 300 transmits a reel start command to the sub control board 400 (Sb3). As shown in FIG. 67, in the present embodiment, a period (wait period) required from when the wait process is started until the wait timer times out is referred to as a period TW1.

  After transmitting the reel start command, the main control board 300 accelerates each reel 12 to the speed of steady rotation. In the present embodiment, a period required until each reel 12 rotates normally after the reel start command is transmitted (that is, a period until the above-described acceleration wait timer expires) is referred to as a period TW2. After the period TW2 elapses, the main control board 300 starts the reel stop control process (Sb4) and enables the stop operation of each stop button 25 to be accepted.

  In order to stop each reel, the player performs a stop operation of each stop button 25 at an arbitrary timing (Sa2). In the present embodiment, for the sake of explanation, the period from the start of the reel stop control process to the end of the stop operation of each reel 12 is referred to as a period TA. The main control board 300 transmits a stop operation command to the sub control board 400 every time each stop button 25 is stopped (Sb5).

  As shown in FIG. 67, after all the reels 12 are stopped, the main control board 300 starts a display determination process (Sb6) and transmits a display winning combination command to the sub-control board 400 (Sb7). ).

  As shown in FIG. 67, when the G-th game is completed, the main control board 300 starts a game start pre-process in the G + 1-th game (Sb8). When the pre-game start process is started and the medal insertion operation can be accepted, the player performs the betting medal insertion operation in the G + 1th game (Sa3). In the present embodiment, for the sake of explanation, the period from the end of the G-th game to the end of the G + 1-th game medal insertion operation is referred to as a period TB. In the present embodiment, for the sake of explanation, a period from when the player completes the medal insertion operation until the start lever 24 is operated is referred to as a period TC.

  As described above, the monitoring period TY is shorter than the period from the operation of the start lever 24 in the G-th game to the operation of the start lever 24 in the G + 1-th game. Specifically, the minimum value of the period TW1 from the start of the wait process to the time-up of the wait timer, the minimum value of the period TW2 required from the start of each reel 12 to the steady rotation, and the stop button 25 being stopped. Time shorter than the sum of the minimum value of the period TA required for the operation, the minimum value of the period TB required for the medal insertion operation, and the minimum value of the period TC required for the operation of the start lever 24 (hereinafter referred to as “minimum operation period Tm”). The length is set as the time length of the monitoring period TY (TY <TA + TB + TC + TW1 + TW2 = Tm).

  Each minimum value of each period T (A to C, W1, W2) can be obtained from, for example, a plurality of experiments. However, depending on the length of time (period TB and period TC) from the end of the previous game until the start lever 24 of the current game is operated, the wait timer may be The time may be up. In the above case, the time length of the period TW1 in the current game is substantially “0”. That is, the minimum value of the period TW1 is substantially “0”.

  In the present embodiment, since the monitoring period TY is set shorter than the minimum operation period Tm, the start operation command is prevented from being received by the sub control board 400 during the monitoring period TY. Therefore, the malfunction that a regular command is detected as an illegal command is suppressed.

  FIG. 68 is a flowchart of the effect button input task. When starting the effect button input task, the sub CPU 412 determines whether or not the effect button 26 or the direction designation button 27 is operated (S307-1). When determining that the effect button 26 or the direction designation button 27 is not operated (S307-1: NO), the sub CPU 412 ends the effect button input task. On the other hand, when it is determined that the effect button 26 or the direction designation button 27 is operated (S307-1: YES), the sub CPU 412 determines whether or not the demonstration effect flag is in the ON state (S307-2).

  If it is determined that the demonstration effect flag is in the ON state (S307-2: YES), the sub CPU 412 executes a menu screen display process (S307-3). In the menu screen display process, the sub CPU 412 displays the menu screen on the liquid crystal display device 30. Further, the sub CPU 412 receives an operation of the effect button 26 or the direction designation button 27 in the menu screen display process during the period in which the menu screen is displayed, and controls the menu screen according to the operation. For example, the combination of symbols of each winning combination is displayed on the liquid crystal display device 30 in accordance with the operation of the effect button 26 or the direction designation button 27. After executing the menu screen display process, the sub CPU 412 ends the effect button input task.

  If it is determined in step S307-2 that the demonstration effect flag is not in the ON state (S307-2: NO), the sub CPU 412 determines whether or not the effect button instruction flag is in the ON state (S307-4). . When determining that the effect button instruction flag is in the ON state (S307-4: NO), the sub CPU 412 ends the effect button input task.

  When it is determined that the effect button instruction flag is in the ON state (S307-4: YES), the sub CPU 412 executes an effect button operation process (S307-5). In the effect button operation process, the sub CPU 412 executes a predetermined effect. For example, with the operation of the effect button 26 as an opportunity, an effect screen for notifying the result of the ART lottery process is displayed on the liquid crystal display device 30. After performing the effect button operation process, the sub CPU 412 ends the effect button input task.

Second Embodiment
A second embodiment of the present invention will be described below. In addition, about the element in which an effect | action and a function are equivalent to 1st Embodiment in each form illustrated below, the code | symbol referred by description of 1st Embodiment is diverted, and each detailed description is abbreviate | omitted suitably.

  Part (a) of FIG. 69 is a conceptual diagram of an unauthorized pattern table in the second embodiment. The illegal pattern table is stored in the sub ROM 413, for example. Further, the illegal pattern table is configured to include illegal pattern data Pd as shown in part (a) of FIG. The illegal pattern data Pd is referred to when it is determined whether or not the reception period TX of the start operation command matches a predetermined illegal pattern. Specifically, the illegal pattern table includes a plurality of types of illegal pattern data Pd, and each illegal pattern data Pd indicates different illegal patterns.

  Part (b) of FIG. 69 is a conceptual diagram of reception pattern data indicating a time series (hereinafter referred to as “reception pattern”) of the reception interval TX of the start operation command. The reception pattern data is stored in the sub RAM 414, for example. The reception pattern data in part (b) of FIG. 69 is reception pattern data when L + 1 start operation commands are received. As shown in part (b) of FIG. 69, the reception pattern data is a time series of L reception intervals TX.

  For example, in the game information update process, the sub CPU 412 determines whether or not the reception pattern indicated by the reception pattern data matches the illegal pattern. Specifically, every time the sub CPU 412 receives L + 1 start operation commands, the sub CPU 412 generates reception pattern data that is a time series of the reception intervals TX (TX1 to TXL) at which the L + 1 commands are received. The sub CPU 412 determines whether or not the reception pattern indicated by the reception pattern data matches any of the illegal patterns indicated by the illegal pattern data in the illegal pattern table.

  The fraud pattern indicated by the fraud pattern data is determined in consideration of, for example, the tendency of the time interval at which the fraud command from the fraud board is received. Specifically, the illegal command reception interval from the illegal board tends to be shorter than the regular command reception interval generated in accordance with the player's operation timing. Considering the above situation, for example, when there are N consecutive reception intervals TX of 2000 ms or less in the reception pattern data, it is determined that the reception pattern indicated by the reception pattern data matches the illegal pattern.

  In addition, the regular command reception interval generated in accordance with the player's operation usually has some variation. On the other hand, illegal commands generated by illegal boards tend to be received at regular intervals (for example, at regular intervals). Considering the above circumstances, for example, when the difference in time length between the longest reception interval TX and the shortest reception interval TX of the reception pattern data is within a predetermined range (for example, within 4 ms), the reception pattern data is The received reception pattern is determined to match the illegal pattern. For example, when the longest reception interval TX among the L reception intervals TX of the reception pattern data is 3003 ms and the shortest reception interval TX is 2999 ms, it is determined that the reception pattern indicated by the reception pattern data matches the illegal pattern. The According to the above configuration, an illegal command transmitted at a substantially constant time interval (regular interval) can be detected. Note that the type of illegal pattern indicated by the illegal pattern data is not limited to the above-described content.

  In the second embodiment, the same effect as that of the first embodiment can be obtained. In the second embodiment, a plurality of types of illegal patterns can be detected. For example, in the first embodiment, an unauthorized command transmitted during a period other than the monitoring period TY among the unauthorized commands is not detected. On the other hand, according to the second embodiment, it is possible to detect even an illegal command received outside the period corresponding to the monitoring period TY of the first embodiment. Therefore, the effect that fraud is suppressed is particularly remarkable.

<Third Embodiment>
FIG. 70 is a flowchart of the game information update process in the third embodiment. When the sub CPU 412 receives a winning area command indicating a winning area, the sub CPU 412 executes the game information update process of FIG. In the third embodiment, a privilege (ART) is awarded when a specific winning combination (re-playing combination) is won in each predetermined number of consecutive games (four times).

  When the game information update process is started, the sub CPU 412 acquires the current value of the monitoring timer (S701), and then determines whether or not the monitoring timer acquired in step S701 is a numerical value “0” (S702).

  If it is determined that the monitoring timer is the numerical value “0” (S702: YES), the monitoring timer is reset to the initial value “M” (S703). On the other hand, when the sub CPU 412 determines that the monitoring timer is not the numerical value “0” (S702: NO), the abnormal reception counter is added (S704), and whether or not the abnormal reception counter is the numerical value “N” or more. Is determined (S705). If it is determined that the abnormal reception counter is greater than or equal to the numerical value “N” (S705: YES), the sub CPU 412 proceeds to error processing. On the other hand, when it is determined that the abnormal reception counter is not greater than or equal to the numerical value “N” (S705: NO), the sub CPU 412 proceeds to step S703.

  In step S706, the sub CPU 412 determines whether or not the current performance state is one of a normal low probability state, a normal high probability state, or a fake state. If it is determined that the performance state is not one of the normal low probability state, the normal high probability state, or the fake state (S706: NO), the sub CPU 412 ends the game information update process. On the other hand, if it is determined that the performance state is one of the normal low probability state, the normal high probability state, or the fake state (S706: YES), the sub CPU 412 proceeds to step S707.

  In step S707, the sub CPU 412 updates the winning area history (game information) according to the winning area indicated by the winning area command. The winning area history indicates the type of each winning area won in each of the four consecutive games. For example, in each of the four consecutive games, when winning in the order of the winning area “push order bell”, “losing”, “losing”, and “RT1 pushing order replay”, the winning area history is “push order bell, lost, lost, “RT1 push order replay”. In the above case, when the winning area “weak cherry” is further won, the winning area history is updated to “weak cherry, push order bell, lost, lost”.

  When the winning area history is updated, the sub CPU 412 determines whether or not the winning area “RT1 push order replay” has been won in each of the four consecutive games (S708). Specifically, it is determined whether or not the winning area history has been updated to “RT1 push order replay, RT1 push order replay, RT1 push order replay, RT1 push order replay”. When it is determined that the winning area “RT1 push order replay” has been won four times in succession (S708: YES), the sub CPU 412 adds a numerical value “1” to the ART set counter (S709). Further, after adding the ART set counter, the sub CPU 412 changes the effect state to the ART latent state (S710), and ends the game information update process. On the other hand, when it is determined that the winning area “RT1 push order replay” has not been won four times in succession (S708: NO), the sub CPU 412 performs the game information update process without updating the ART set counter and the effect state. finish.

  According to 3rd Embodiment, there can exist an effect similar to 1st Embodiment. In the third embodiment, the reception interval TX of each winning area command is monitored in a configuration in which a privilege is given according to the history of the results of the internal lottery process in each successive game. Therefore, the illegal command transmitted in order to obtain the above-described privilege can be detected. For example, when the winning area command is received three times (N = 3) in the monitoring period TY, a configuration in which error processing is executed is preferable. According to the above configuration, for example, by transmitting the unauthorized command indicating the winning area “RT1 push order replay” to the sub-control board 400 four times in succession, it is possible to prevent the unauthorized act of obtaining the above-described privilege.

  Note that the game information updated in accordance with the winning area command is not limited to the winning area history described above. For example, you may employ | adopt the continuous winning number counter which shows the frequency | count that the winning combination "RT1 pushing order replay" was won continuously. Specifically, the consecutive winning counter is incremented by a numerical value “1” when the winning combination “RT1 push order replay” is won, and a numerical value “0” when other than the winning combination “RT1 push order replay” is won. Cleared. In the above configuration, a privilege is granted when the continuous winning counter is updated to the numerical value “4”.

<Fourth embodiment>
FIG. 71 is a flowchart of the game information update process in the fourth embodiment. When the sub CPU 412 receives the spinning effect type command, the sub CPU 412 executes a game information update process shown in part (a) of FIG. Further, when the sub CPU 412 receives a reel start command, the sub CPU 412 executes a game information update process shown in part (b) of FIG. In 4th Embodiment, when execution of a reverse rotation effect is determined among the rotation effects of each reel 12, a privilege (ART) is provided.

  When the game information update process shown in part (a) of FIG. 71 is started, the sub CPU 412 determines whether or not execution of the reverse rotation effect is determined in the spinning effect control process (S801). If it is determined that the reverse rotation effect has been determined (S801: YES), the sub CPU 412 sets the reverse rotation effect execution flag (game information) to the ON state (S802), and resets the monitoring timer to the initial value (S803). ), The game information update process is terminated. The initial value of the monitoring timer of this embodiment is “about 30000 ms”, which is substantially equal to the length of the period during which the reverse rotation effect is executed. On the other hand, if it is determined that the reverse rotation effect has not been determined (S801: NO), the sub CPU 412 ends the game information update process without resetting the reverse rotation effect execution flag and the monitoring timer.

  When the game information update process shown in part (b) of FIG. 71 is started, the sub CPU 412 determines whether or not the reverse rotation effect execution flag is in the ON state (S901). If it is determined that the reverse rotation effect execution flag is not in the ON state (S901: NO), the sub CPU 412 ends the game information update process. On the other hand, when the reverse rotation effect execution flag is in the ON state (S901: YES), the sub CPU 412 acquires the current value of the monitoring timer (S902), and determines whether or not the monitoring timer has expired (S903). ). Since the reel start command is transmitted from the main control board 300 at the time when the monitoring timer has timed out, the monitoring timer has timed out at the time of execution of the game information update process shown in part (b) of FIG. . If it is determined that the monitoring timer has expired (S903: YES), the sub CPU 412 adds a numerical value “3” to the ART set counter (S904), and shifts the effect state to the ART preparation state (S905). On the other hand, if it is determined that the monitoring timer has not expired (S903: NO), the sub CPU 412 sets the reverse rotation effect execution flag to the OFF state (S906), and proceeds to error processing.

  FIG. 72 is a system sequence diagram for explaining the operation of the gaming machine 1 in the fourth embodiment. As shown in part (a) of FIG. 71, when a spinning effect type command (reverse rotation effect) is transmitted from the main control board 300 (Sc1), the sub-control board 400 turns on the reverse rotation effect execution flag. (Sd1). Further, when the reverse effect execution flag is set to the ON state, the monitoring period TY starts. The main control board 300 causes each reel 12 to execute a reverse rotation effect after transmitting the spinning effect type command (Sc2). When the reverse rotation effect is finished, the main control board 300 transmits a reel start command (Sc3). When receiving the reel start command, the sub-control board 400 increments the ART counter (Sd2).

  Part (b) of FIG. 72 is a system sequence diagram for explaining the operation of the sub-control board 400 to which the unauthorized board is connected. When the sub-control board 400 receives the illegal command (command imitating the spinning drum production command), the sub-control board 400 sets the reverse rotation production execution flag to the ON state (Se1). Thereafter, when an illegal command (a command imitating a reel start command) is received in the monitoring period TY, the reverse rotation effect execution flag is set to the OFF state (Se2), and then the process proceeds to error processing (Se3).

  As understood from the above description, in the fourth embodiment, the sub control board 400 updates the reverse rotation effect execution flag (game information) to the ON state when receiving the spinning effect type command. However, when the reel start command is received in the monitoring period TY after the reverse rotation effect execution flag is updated to the ON state, the reverse rotation effect execution flag is returned to the OFF state, and the update of the reverse rotation effect execution flag is cancelled. In other words, the time interval from the time when the reel production effect type command is received to the time when the reel start command is received is monitored, and if the time interval is shorter than a predetermined time length, the reverse rotation effect is substantially executed. Flag update is prohibited.

  In the fourth embodiment, the same effect as that of the first embodiment can be obtained. Moreover, in 4th Embodiment, the time interval which received each specific command (Rotation effect type command and Revolving effect type command) from which a type mutually differs is monitored. For example, in a configuration in which a privilege is given by receiving the first command (rotation effect type command) once, an illegal act of obtaining a privilege by transmitting an illegal command only once is assumed. In the above configuration, it is difficult to detect the fraud by the technique for monitoring the reception interval of the first command (a configuration in which the first command received second time can be detected as an illegal command). In the fourth embodiment, when the second command is detected as an illegal command by monitoring the reception interval between the first command and a second command (reel start command) having a different type from the first command, Granting of a privilege by the first command can be prohibited.

<Modification>
Each of the above forms can be variously modified. Specific modifications are exemplified below. Two or more aspects arbitrarily selected from the following examples can be appropriately combined.

(1) The type of a specific command whose reception interval is monitored is not limited to the above-described modes. For example, when the display winning combination command is received, the game information (for example, the game counter) may be updated, and the time interval at which the display winning combination command is received may be monitored.

(2) The type of game information that is updated when a specific command is received is not limited to the above-described forms. For example, a latent counter indicating the number of remaining games in the ART latent state may be provided, and the latent counter may be updated (subtracted) when a start operation command is received. According to the above configuration, it is possible to detect an illegal act in which the latent counter is subtracted by an illegal command.

(3) In the fourth embodiment, the reception interval between the spinning production effect type command and the reel start command is monitored. However, the reception interval of each command in another combination may be monitored. For example, the reception interval between the reel start command and the stop operation command during the first stop operation may be monitored. The monitoring period TY of the configuration is provided in a period from the time when the reel start command is received to the time when the stop operation command is received, and is set to a time length shorter than the period TW2 (see FIG. 67). Further, for example, the reception interval between the start operation command and the display winning combination command may be monitored. The monitoring period TY of the configuration is provided in the period from the time when the start operation command is received to the time when the display winning combination command is received, and is the sum of the minimum value of the period TW1, the minimum value of the period TW2, and the minimum value of the period TA. A shorter time length is set.

(4) In each of the above embodiments, an error notification may be provided when an illegal command is detected. For example, in the first embodiment, when a start operation command is received during the monitoring period TY, the sub control board 400 causes the liquid crystal display device 30 to display an error message. According to the above configuration, the effect of suppressing fraudulent acts due to fraudulent commands is particularly remarkable.

(5) In each of the above embodiments, a gaming penalty may be given when an illegal command is detected. For example, in the first embodiment, when the start operation command is received during the monitoring period TY, the sub CPU 412 stops the process related to each lottery including the ART lottery process. According to the above configuration, a penalty for gaming is given to a person who commits cheating, and thus the effect of suppressing cheating is particularly remarkable.

(6) The content of the privilege granted when the game information satisfies the privilege granting conditions is not limited to the above-described forms. For example, in the ART state, a bell winning counter that is updated every time the winning area “push order bell” is won is provided, and when the bell winning counter reaches a predetermined numerical value, the right to shift to the specialization state is granted. It is good also as a structure. In the above configuration, for example, by monitoring the time interval at which the winning area command is received, it is possible to detect an illegal act of obtaining a privilege based on the illegal command.

(7) By the way, even if an illegal command has not been received, the possibility of adding an abnormal reception counter may not be completely excluded due to, for example, the influence of electrical noise. Suppose that the abnormal reception counter is added by noise at an average frequency of once every time the gaming machine 1 operates for X hours. In the above case, in the first embodiment and the third embodiment described above, there is a problem that error processing due to noise is executed with an average frequency of X × N hours (that is, an incorrect command is erroneously detected). . In view of the above circumstances, a configuration that resets the abnormal reception counter at a predetermined time is preferable. For example, a configuration may be considered in which an abnormal reception counter is reset when a specific command is normally received. According to the above configuration, a situation where the abnormal reception counter is incremented up to the numerical value N due to the influence of noise or the like is suppressed.

(8) In each of the above embodiments, the sub control board 400 may be provided with a command buffer capable of storing a plurality of commands transmitted by the main control board 300. In the above configuration, the sub CPU 412 reads a command from the command buffer every 50 ms, for example. The read command is erased from the command buffer.

  By the way, in 3rd Embodiment mentioned above, an abnormal reception counter is added by the game information update process performed every 50 ms. Therefore, even if an illegal command is transmitted at a time interval of 50 ms or less (for example, about 2 ms), the process proceeds to error processing after a period of time length obtained by multiplying the abnormal reception counter threshold value “N” by 50 ms. And do not go to error handling before that.

  Therefore, in the configuration including the command buffer described above, a configuration may be adopted in which error processing is executed when a predetermined number of commands or more are stored in the command buffer. According to the above configuration, error processing is executed when commands are continuously stored within a time interval at which commands are read from the command buffer. Further, according to the above configuration, it is possible to shift to error processing before the command read period (50 ms) elapses after the transmission of the illegal command is started. For example, it is assumed that an illegal command is transmitted at a time interval of about 2 ms to the sub-control board 400 having an upper limit number of command buffers of “Y” (Y <25) and a command reading interval of about 50 ms. . In the above case, the process proceeds to error processing about Y × 2 ms (<50 ms) after the transmission of the illegal command is started. However, the upper limit number of command buffers can be set as appropriate.
