Description

  The present invention relates to a gaming machine such as a pachinko gaming machine, and in particular, a main machine provided in a gaming machine that plays a jackpot game when a numerical value for jackpot determination obtained for each winning of a starting opening matches a predetermined numerical value. The present invention relates to a control board, a gaming machine including the main control board, and a program to be executed by the main control board.

  Conventionally, a gaming machine such as a pachinko machine, for example, acquires a jackpot determination value when a game ball wins a specific winning opening (at the time of starting winning), and the acquired number matches a predetermined jackpot value. If you want to play a jackpot game. The gaming machine, for example, acquires the count value at the time of starting winning as a numerical value for jackpot determination from the count values obtained by incrementing a numerical value given as an initial value random number every predetermined time.

  Specifically, such a gaming machine is, for example, 0, 1, 2,... 305, 306, a numerical value for jackpot determination from a group of numerical values constituted by a predetermined number of numerical values. To get. In such a gaming machine, for example, when the count value reaches 306, the next count value is set to 0, and the count value is looped by a numerical value in the above numerical value group (for example, Patent Document 1 below). See).

  In the above gaming machine, the time for which the count value loops once is constant, and the same count value appears every fixed time. Therefore, if the predetermined time for incrementing the count value is known, a specific count is given from the outside of the gaming machine. It becomes possible to predict the appearance timing of values. For this reason, the above-described gaming machine is likely to be a target of a fraudulent act (so-called goto act) in which a specific count value predicted as a jackpot value is acquired as a value for jackpot determination and the jackpot game is played at a high frequency.

  As a countermeasure against such an illegal act, for example, when the count value obtained by adding +1 and the initial value random number become the same numerical value, that is, when the count value is one loop, an initial value random number different from the previous one is given. There was technology that did. Accordingly, it is possible to make it difficult to predict the appearance timing of a specific count value from the outside of the gaming machine by changing the numerical value for starting counting for one loop.

  Some conventional gaming machines initialize game information such as a previous count value or initial value random number when power is supplied under predetermined conditions. The predetermined condition is, for example, when a predetermined operation is performed together with a power supply operation to the main control board, or when a power supply operation is performed after the power supply to the main control board is cut off without valid backup data. is there. In such a gaming machine, both the count value and the initial value random number are set to 0 (zero) by initialization, and after initialization, the numerical value for jackpot determination is obtained from the state where both the count value and the initial value random number are 0 (zero). To start.

JP 2000-107387 A

  However, in the conventional techniques including the above-described document 1, since the count value and the initial value random number start from 0 (zero) after the initialization, the count value is looped by 1 since the acquisition of the numerical value for jackpot determination is started. Even if an initial value random number different from the previous time is given, there is a problem that it is possible to predict the appearance timing of a specific count value from the outside of the gaming machine immediately after the initialization.

  And such a gaming machine generates a jackpot value from the outside of the gaming machine by illegally creating a state in which both the count value and the initial value random number are set to 0 (zero) and acquiring the timing at which power supply is started. Because it is possible to predict the appearance timing of a specific count value predicted as, it is likely to be a target of fraudulent acts (so-called goto acts) in which a specific numerical value is acquired as a numerical value for jackpot determination and the jackpot game is played at a high frequency There was a problem.

  Specifically, for example, an illegal signal is input from the outside of the gaming machine via an illegal board connected to the main control board, and the power is supplied again after the power supply to the main control board is cut off. Incorrectly creating a state in which both random numbers are set to 0 (zero), and obtaining the timing at which power supply is started has been performed.

  In order to eliminate the above-described problems caused by the prior art, the present invention predicts the appearance timing of a specific count value from the outside of the gaming machine, acquires the specific numerical value as a numerical value for jackpot determination, An object of the present invention is to provide a main control board, a gaming machine, and a program that can prevent fraudulent acts that can be performed in the game.

  The main control board according to the invention of claim 2 is the main control board according to claim 1, wherein the selection means detects an operation signal by the detection means from a predetermined number of numerical values that circulate in a predetermined order. And the acquisition means appears at a winning point of the start opening from among a predetermined number of numbers that circulate in the predetermined order with the numerical value selected by the selection means as an initial value. The numerical value to be obtained is acquired as the numerical value for determining the jackpot.

  Here, for example, cyclic means that a numerical value stored in a buffer is stored such that one numerical value of a predetermined number of numerical values is stored as a count value in a predetermined buffer and all numerical values appear as a count value once. It is assumed that the update is performed according to a certain order and the process is related to the update.

  Specifically, for example, when 10 numerical values from 0 to 9 exist as a predetermined number of numerical values, if 0 is an initial value, count values are in the order of 0, 1, 2,. Is updated, and when the count value reaches 9, one round (loop) is performed. In addition, for example, when there are 10 numerical values from 0 to 9 as a predetermined number of numerical values, for example, when 5 is an initial value, 5, 6, 7... The count value is updated, and when the count value reaches 4, one round (loop) is performed.

  The main control board according to a third aspect of the present invention is the main control board according to the first or second aspect, wherein the detecting means is an operation indicating that an operation to start updating the numerical value for determining the jackpot is performed. A signal is detected.

  According to a fourth aspect of the present invention, in the main control board according to the third aspect of the present invention, the detecting means is an operation indicating that an operation for starting updating the numerical value for determining the jackpot has been performed a predetermined number of times. A signal is detected.

  According to a fifth aspect of the present invention, in the main control board according to the first or second aspect, the detecting means detects an operation signal indicating that a predetermined plurality of types of key operations have been performed. It is characterized by.

Exemplary embodiments of a main control board, a gaming machine, and a program according to the present invention will be described below in detail with reference to the accompanying drawings.

(Basic configuration of gaming machine)
FIG. 1 is a front view showing an example of the gaming machine of the present invention. The gaming machine of the present invention includes a game board 101. A glass frame lamp (see reference numeral 262 in FIG. 2) is provided on the surface of the game board 101. The gaming machine drives and controls the glass frame lamp by a lamp control unit (see reference numeral 230 in FIG. 2) to turn on or blink the glass frame lamp. Thereby, the effect of the game can be enhanced.

  A launcher (not shown) is disposed at a lower position of the game board 101. The launcher launches a game ball into the game area 103. The game ball launched by the launching unit rises between the rails 102 a and 102 b and reaches the upper position of the game board 101, and then falls within the game area 103.

  The game area 103 is provided with a plurality of nails (not shown). In the game area 103, a windmill (not shown) is disposed. A plurality of nails, windmills, and the like change the falling direction of the game ball falling in the game area 103. A symbol display unit 104 is arranged at the center of the game area 103.

  The symbol display unit 104 can be realized by a liquid crystal display (LCD), for example. A start winning opening 105 is disposed below the symbol display unit 104. When a game ball wins the start winning opening 105, the gaming machine acquires a jackpot determination random number as a numerical value for jackpot determination. In this embodiment, any one numerical value selected from integers from 0 to 306 is acquired as a jackpot determination random number. Details of the jackpot determination random number will be described later (see FIG. 6).

  A winning gate 106 is disposed on the side of the symbol display unit 104. When the gaming machine detects that the game ball has passed the winning gate 106, the gaming machine opens the start winning opening 105 for a predetermined time. Further, when the game ball wins the start winning opening 105 (start winning), the gaming machine displays a plurality of symbols in the symbol display unit 104 variably, stops the variation display after a predetermined time, and displays an arbitrary symbol.

  At this time, the gaming machine changes the content of the symbol to be displayed depending on whether or not the acquired jackpot determination random number matches a predetermined numerical value (jackpot value). The jackpot value in this embodiment is an arbitrary numerical value in a numerical group including an integer from 0 to 306. The jackpot value is predetermined for each gaming machine, for example, when the gaming machine is manufactured, and is stored in a predetermined storage area (see reference numeral 212 in FIG. 2).

  The gaming machine sets the jackpot state when the acquired jackpot determination random number matches the jackpot value, and displays a jackpot effect image on the symbol display unit 104. The gaming machine displays an image in which specific symbols (for example, “777”) are aligned when the variable display is stopped, for example, in the big hit state.

  A plurality of normal winning holes 107 are arranged on the side and below the symbol display unit 104. When a gaming ball wins any one of the plurality of normal winning holes 107, the gaming machine pays out the number of game balls (for example, 10) at the time of the normal winning. Below the game area 103, a special winning opening 109 is provided. When the gaming machine is in a big hit state, it opens the big prize opening 109 for a certain period. Then, the gaming machine repeats opening of the special winning opening 109 for a predetermined round (for example, 15 rounds), and pays out the number of prize balls corresponding to the winning game balls.

  The big prize opening 109 is closed by a big prize door 109a in a state other than the big hit state. The big prize opening 109 and the big prize door 109a are a big prize opening / closing switch for detecting opening / closing of the big prize opening 109, a left count switch and a right count switch for detecting a game ball won in the big prize opening 109 (both shown) And the attacker is configured. A recovery port 108 is provided at the bottom of the game area 103. The collection port 108 collects game balls that have not won any of the above-described winning ports.

  A frame member 110 is provided on the outer peripheral portion of the game area 103 of the game board 101. The frame member 110 has a shape that surrounds the periphery of the game area 103 on the four sides of the game board 101 in the vertical and horizontal directions. Further, the frame member 110 has a shape protruding from the board surface of the game board 101 toward the player side. Thereby, the gaming machine of this embodiment can be made more conspicuous than other types of gaming machines that do not include the frame member 110. By making the gaming machine conspicuous, it is possible to improve the operating rate of the gaming machine and to strengthen the deterrent against fraudulent acts on the gaming machine.

  In the frame member 110, the effect light portions 111 are provided on the two sides on the upper side and the lower side of the game area 103. Each effect light unit 111 includes a plurality of lights 112. Each light 112 includes a decoration LED (see reference numeral 261 in FIG. 2), and the light irradiation direction can be changed in the vertical direction. In addition, the effect light unit 111 can rotate the light irradiation direction. The gaming machine includes a motor (not shown) that changes the irradiation direction of the light emitted by each light 112.

  The gaming machine changes the direction of light irradiation by the effect light unit 111 when, for example, a big hit state occurs. Thereby, it is possible to inform the surroundings that the gaming machine is in the big hit state, and the degree of attention of the player who has been in the big hit state can be increased. This gives the player a sense of excitement due to attention, and allows the gaming machine of this embodiment to be used continuously or repeatedly to improve the operating rate of the gaming machine.

  Further, the light irradiation direction may be changed when, for example, an abnormal situation different from that in a normal game occurs. The abnormal situation here is, for example, a case where some kind of fraudulent act is performed on the gaming machine. As a result, it is possible to quickly find fraud and to enhance the deterrence of the next and subsequent fraud on the gaming machine.

  An operation handle 113 is disposed at a lower position of the frame member 110. The operation handle 113 is operated by the player when the game ball is fired by driving the launching unit. Similar to the frame member 110 described above, the operation handle 113 has a shape protruding from the board surface of the game board 101 to the player side.

  The operation handle 113 includes a firing instruction member 114 that drives the above-described launching unit to launch a game ball. The firing instruction member 114 is provided on the outer peripheral portion of the operation handle 113 so as to rotate clockwise as viewed from the player. The launcher causes the game ball to be launched when the firing instruction member 114 is directly operated by the player. The operation handle 113 includes a sensor that detects that the player is directly operating the firing instruction member 114.

  The game board 101 may be provided with an effect for the effect (hereinafter referred to as an “effect effect”) at a position other than the display area of the symbol display unit 104. The director is provided with the above-described decoration LED, for example. In this case, the gaming machine can enhance the effect by controlling the light emission timing of the LED included in the effect agent.

  Further, the directing agent may be a movable directing agent that operates by receiving a driving force such as a motor or a solenoid (both not shown). The movable director may operate in conjunction with the image display operation in the symbol display unit 104. The gaming machine can enhance the effect of the effect by linking the operation of the effect actor and the image display operation in the symbol display unit 104 in this way.

  In the frame member 110, a chance button 117 that accepts an operation by the player is provided on the lower side of the game area 103. In this embodiment, the chance button 117 has a convex button shape. The chance button 117 may be an input pad that employs a touch panel system in addition to the convex button. The operation of the chance button 117 is effective while guidance for prompting the operation of the chance button 117 is displayed, for example, in the case of a specific reach effect during the game.

  On the frame member 110, a cross key 118 is provided next to the chance button 117. The cross key 118 includes a cursor key for changing a position indicating a character or a graphic displayed on the symbol display unit 104, and an “ENTER” key (not shown) for confirming the character or the graphic selected by operating the cursor key. And).

  Further, the frame member 110 incorporates a lower bus SP (see reference numeral 271 in FIG. 2) for outputting sound and an upper stereo speaker (see reference numeral 272 in FIG. 2). The gaming machine outputs sound corresponding to the display content of the symbol display unit 104, for example, from the upper stereo speaker or the lower bus SP. This can enhance the production effect.

(Internal configuration of control unit of gaming machine)
FIG. 2 is a block diagram showing the internal configuration of the control unit of the gaming machine. The control unit of the gaming machine is composed of a plurality of control units. In FIG. 2, the control unit includes a main control unit 210, a symbol control unit 220, a lamp control unit 230, and a sound control unit 240. The main control unit 210, the symbol control unit 220, the lamp control unit 230, and the sound control unit 240 are provided on separate substrates.

  The main control unit 210 controls basic operations related to gaming of the gaming machine. The main control unit 210 can realize its function by, for example, a main board. The main controller 210 includes a CPU 211, a ROM 212, a RAM 213, I / Os 214 to 216, and a ram clear switch 217. The CPU 211 executes basic processing associated with the progress of game content based on the program stored in the ROM 212.

  The RAM 213 functions as a data work area when the CPU 211 performs arithmetic processing. The CPU 211 counts up by +1 with a numerical value from 0 to 306 in one loop. The CPU 211 starts counting up from the time of supplying power to the main control unit 210. Further, after counting for one loop, the CPU 211 performs a loop count such that the next one loop is counted. And CPU211 acquires the count value at the time of starting winning a prize as a jackpot determination random number. The RAM 213 functions as a counter for obtaining such jackpot determination random numbers, for example.

  In this embodiment, any one numerical value in a numerical value group including integers from 0 to 306 is acquired as a jackpot determination random number. Therefore, the CPU 211 counts the numerical values from 0 to 306 by 1 in the counter, and acquires the numerical values in the numerical group including the integers from 0 to 306 as the jackpot determination random numbers.

  The jackpot determination random number varies depending on the timing of winning the start. The determination of the start winning prize will be described later. In this embodiment, as described above, since any one numerical value in the numerical value group including integers from 0 to 306 is a big hit value, a big hit occurs in a gaming machine in which such a count setting is made. The probability of doing is 1/307.

  Each time the CPU 211 acquires the jackpot determination random number, the CPU 211 compares the acquired jackpot determination random number with the jackpot value stored in the ROM 212 to perform a jackpot determination. Specifically, the CPU 211 determines, for example, whether or not the jackpot determination random number matches the jackpot value, and determines that the match is a jackpot.

  The RAM 213 includes an RWM area for storing initial value random numbers and initial value data. The initial value random number is an arbitrary numerical value selected from numerical values from 0 to 306 counted by +1 separately from the numerical value counter for jackpot determination. The initial value random number is a numerical value for designating a start position for starting counting for the next one loop after the numerical counter for jackpot determination has made one loop.

  Specifically, if the initial value random number is 77 when the count (0, 1, 2,..., 305, 306) from 0 to 306 is completed, for example, the CPU 211 determines that the next loop is 77. , 78, 79,..., 306, 0, 1,. If the initial value random number is 115 when the count up to 76 is completed, the next one loop is 115, 116, 117,..., 306, 0, 1,. Count in the order of 114.

  The CPU 211 increments the count value of the initial value random number by 1 at a time different from the count value of the numerical value for jackpot determination. Specifically, for example, the CPU 211 changes the timing of updating the count value of the initial value random number by changing the timing of updating the count value of the numerical value for jackpot determination. Specifically, the CPU 211 performs, for example, the initial value random number update interval and the count value update interval for obtaining the jackpot determination random number at the same interval (for example, 4 msec).

  The initial value data is an initial value random number of a loop that is being counted in order to obtain a jackpot determination random number. For this reason, the initial value data is an arbitrary numerical value selected from numerical values from 0 to 306. The initial value data is determined when counting for one loop is started (see FIG. 6). That is, the initial value data is a numerical value at which counting of one loop currently being counted is started. The initial value random number is a numerical value for starting counting for one loop to be counted next.

  The I / O 214 inputs the signal output from the start switch (start SW) 251 and the signal output from the gate switch (gate SW) 252 to the CPU 211. The start SW 251 and the gate SW 252 can be realized by a proximity sensor, for example. In this case, the start SW 251 and the gate SW 252 output a signal indicating an ON state at a timing when the game ball approaches the switches 251 and 252.

  The CPU 211 monitors the outputs of the start SW 251 and the gate SW 252 every certain time (for example, 4 msec). In the gaming machine, for example, when a game ball passes through the start winning opening 105, the output from the start SW 251 is continuously turned on twice or more. The CPU 211 determines that the game ball has passed through the start winning opening 105 when the output from the start SW 251 is continuously turned on twice or more (see FIG. 11).

  Further, the I / O 214 inputs an output signal from the big prize opening switch (large prize opening SW) 253 to the CPU 211. The special prize opening SW253 can be realized by, for example, a proximity sensor. The CPU 211 detects that the game ball has won the big prize opening 109 based on the output signal from the big prize opening SW253. Further, when the CPU 211 receives that the game ball has won the grand prize opening 109, it outputs a prize ball control signal to the prize ball control unit (not shown).

  The prize ball control unit is a CPU that executes a prize ball control process, a RAM that functions as a data work area during arithmetic processing by the CPU, and data output to the main control unit 210 and a payout unit (not shown). It is configured with I / O etc. When the prize ball control unit receives the prize ball control signal from the main control unit 210, each prize port (starting prize port 105, ordinary prize port 107, big prize) is given to the payout unit connected to the prize ball control unit. Control is performed to pay out the number of prize balls corresponding to the game balls won in the mouth 109). The payout unit includes a motor or the like for paying out a predetermined number from a storage unit (not shown) of game balls.

  The CPU 211 outputs an open / close signal of the big prize opening solenoid 254 to the big prize opening solenoid 254 via the I / O 214 when a big hit occurs. Further, the CPU 211 controls the opening / closing of the big prize opening solenoid 254 so that the big prize opening 109 is opened for a certain period when a big hit occurs. Further, the CPU 211 controls the opening / closing of the big winning opening solenoid 254 so that the opening of the big winning opening 109 is repeated a predetermined round (for example, 15 rounds) when a big hit occurs.

  Further, the I / O 214 inputs output signals from the normal winning opening switch (normal winning opening SW) 255 and 256 to the CPU 211. The normal winning openings SW255, 256 can be realized by a proximity sensor, for example. The CPU 211 detects that the game ball has won the normal winning port 107 based on the output signals from the normal winning ports SW 255 and 256. Further, when the CPU 211 receives that the game ball has won the normal winning slot 107, it outputs a prize ball control signal to the above-described prize ball control unit.

  The I / O 215 inputs an output signal from the ram clear switch 217 to the CPU 211. The ram clear switch 217 outputs a signal indicating an ON state when being pressed. The ram clear switch 217 is provided on, for example, a main board. Accordingly, an operation signal generated by operating the ram clear switch 217 can be directly input to the main control unit 210, and the ram clear signal cannot be input from the outside of the gaming machine.

  The ram clear switch 217 has a structure that is uneven according to the applied external force. Accordingly, the ram clear switch 217 outputs a ram clear signal to the main control unit 210 only when the ram clear switch 217 is directly operated. In other words, it is possible to prevent the ram clear signal from being input from the outside of the gaming machine via an unauthorized harness or board connected to the main board.

  The gaming machine may include a cover member that covers the ram clear switch 217. The cover member is provided to restrict the operation (pressing operation) of the ram clear switch 217. The cover member has a shape and a structure that covers the ram clear switch 217 so that the ram clear switch 217 cannot be operated unless the ram clear switch 217 is opened before the ram clear switch 217 is operated. Note that description of the shape and structure of the cover member 217 is omitted here.

  For example, when power is supplied by operating a power switch (not shown) or the like, the CPU 211 initializes game information of the game when a signal indicating an on state is output from the ram clear switch 217. (Lamb clear). At the time of ram clear, the CPU 211 sets, for example, an initial value random number or initial value data stored in the RWM area to 0 (zero).

  The CPU 211 generates control signals according to various output signals received from the start SW 251, the gate SW 252, the big prize opening SW 253, and the normal prize opening SW 255, 256, and the generated control signal is transmitted to the symbol control unit via the I / O 216. To 220. Further, the CPU 211 generates a control signal according to the power supply state and the output signal from the ram clear switch 217, and outputs the generated control signal to the symbol control unit 220 via the I / O 216.

  The symbol control unit 220 performs effect control of the gaming machine based on the control signal output from the main control unit 210. In this embodiment, the symbol display unit 220 functions as an effect control board. The symbol control unit 220 includes a CPU 221, a ROM 222, a RAM 223, and I / Os 224 to 226.

  The CPU 221 executes an effect process that produces game content based on a control signal from the main control unit 210 and a program stored in the ROM 212 via the I / O 224. The ROM 222 stores various programs related to the execution of the rendering process and various image data displayed on the symbol display unit 104. The various image data includes a background image, a design image, a character image, and the like. The RAM 223 functions as a data work area when the CPU 221 performs arithmetic processing.

  The CPU 221 reads a program stored in the ROM 222, for example, and executes various image processing such as background image display processing, symbol image display / variation processing, and character image display processing. Further, the CPU 221 reads out necessary image data from the ROM 222 when executing various image processes, and outputs the read image data to the symbol display unit 104 via the I / O 225. Here, the CPU 221 specifically, for example, a design that produces a game content until winning a prize, a reach (a state in which two of the three symbols are arranged), a design that produces a game content at the time of a big hit, etc. The image data representing is output.

  The symbol display unit 104 writes the image data received from the symbol control unit 220 in a VRAM or the like. The symbol display unit 104 displays the symbol image and the character image so that they can be seen in front of the background image. Specifically, for example, when the display position of the background image and the design image displayed by the design display unit 104 overlaps the same position in the display screen, the Z buffer Z of each image data is obtained by a known hidden surface removal method such as the Z buffer method. By referring to the value, the symbol image is preferentially stored in a VRAM (not shown) or the like.

  The I / O 225 inputs the chance button operation signal from the above-described chance button 117 to the CPU 221. Further, the I / O 225 may input an operation signal from another button other than the chance button 117 to the CPU 221. As another button, for example, an “ENTER” button for specifying the character or graphic selected by the above-described cross key 118 and confirming the specified character or graphic may be provided.

  The CPU 221 is a control signal related to the control of the light emission operation of various light sources provided in the gaming machine such as the decoration LED 261, the glass frame lamp 262, and the side lamp 263 among various signals for performing the rendering process via the I / O 226. Is output to the lamp controller 230. In addition, the CPU 221 outputs a control signal related to audio output control from the lower bus SP 271 and the upper stereo speaker 272 to the audio control unit 240 among various signals for performing the rendering process.

  The lamp control unit 230 performs light emission control of light emitters such as the decoration LED 261, the glass frame lamp 262, and the side lamp 263 in the effect processing performed by the symbol control unit 220. The lamp control unit 230 includes a CPU 231, a ROM 232, a RAM 233, and I / Os 234 and 235.

  The CPU 231 reads a program stored in the ROM based on a control signal from the symbol control unit 220 input by the I / O 234. Then, the CPU 231 controls light emission / extinction of light emitters such as the decoration LED 261, the glass frame lamp 262, and the side lamp 263 by executing the read program. The RAM 233 functions as a data work area when the CPU 231 performs arithmetic processing, and necessary data is written when the CPU 231 turns on / off the light emitter.

  The voice control unit 240 performs voice output processing related to voice output among the effect processing performed by the symbol control unit 220. The voice control unit 240 includes a CPU 241, a ROM 242, a RAM 243, and I / Os 244 and 245. The CPU 241 reads a program stored in the ROM 242 based on a control signal from the symbol control unit 220 input by the I / O 244, performs sound output processing, and outputs sound from the lower bus SP271 and the upper stereo speaker 272. The RAM 243 functions as a data work area during the arithmetic processing of the CPU 241, and data necessary for the voice output processing by the CPU 241 is written as appropriate.

  As shown in FIG. 2, in this embodiment, the main control unit 210, the symbol control unit 220, the lamp control unit 230, and the voice control unit 240 having the above-described configuration are different from each other in the printed circuit board (main board, sub board). , Lamp control board and sound control board). The main control unit 210, the symbol control unit 220, the lamp control unit 230, and the voice control unit 240 are not limited to being provided on different substrates. For example, a part or all of the control units can be provided on the same printed circuit board, such as providing the symbol control unit 220, the lamp control unit 230, and the sound control unit 240 on the same printed circuit board.

(Functional configuration of main control unit)
Next, a functional configuration of the main control unit (main board) 210 will be described. FIG. 3 is a block diagram showing a functional configuration of the main control unit 210 and its surroundings. In FIG. 3, the main control unit 210 includes a power detection unit 301, a detection unit 302, a selection unit 303, a storage unit 304, a count unit 305, a backup unit 306, a determination unit 307, a control unit 308, , And an output unit 309.

  The power detection unit 301 detects whether power is supplied to the main control unit 210. The power of the gaming machine is cut off when, for example, an operation for turning off the power switch is performed, and is supplied when an operation for turning on the power switch is performed. In addition, the power supply of the gaming machine is cut off when the function of the power supply itself stops due to, for example, a power failure, and automatically when the power failure is released and the function of the power supply itself is restored, or when the power is turned on Supplied.

  When the power is shut off, the voltage gradually decreases from the voltage value of the substrate having a large voltage. For example, based on the voltage value of the power supplied to the main control unit 210, the power detection unit 301 determines that the supply of power to the main control unit 210 is interrupted when the voltage value falls below a predetermined value. To do. When the power supply is shut off due to a power failure or the like, the power supply may be restored to a predetermined value or more before the voltage value falls below the predetermined value. The function of the power supply detection unit 301 can be realized by the CPU 211, for example.

  When power is supplied to the main control unit 210, the detection unit 302 detects an operation signal indicating that a predetermined operation has been performed after the power supply. The detection unit 302 detects a ram clear signal output after power is supplied, for example. That is, the detection unit 302 detects that the ram clear switch 217 is pressed together with the power switch after the power is supplied. In this embodiment, it is detected that the ram clear switch 217 is pressed once together with the power switch.

  The detection unit 302 may detect a ram clear signal output a predetermined number of times after power is supplied, for example. That is, the detection unit 302 may detect that the ram clear switch 217 is pressed a predetermined number of times together with the power switch. Here, the predetermined number of times can be set to an arbitrary number of times of two times or three times or more. The function of the detection unit can be realized by the CPU 211 and the I / O 214, for example.

  Further, the detection unit 302 may detect an operation signal indicating that a predetermined plurality of types of key operations have been performed. The predetermined plural kinds of key operations are operations other than pressing the ram clear switch 217 together with the power switch, and can be realized, for example, by pressing the chance button 117 together with the power switch. Further, predetermined plural types of key operations may be realized by pressing the ram clear switch 217 together with the chance button 117, for example. The detection unit 302 can realize its function by, for example, the CPU 211, the I / O 215, the ROM 212, the power switch, and the ram clear switch 217.

  The selection unit 303 selects an arbitrary numerical value within a range of numerical values (integer of 0 to 306) used for acquiring the jackpot determination random number. Specifically, for example, when the detection unit 302 detects an operation signal indicating that a predetermined operation has been performed after the power is supplied, the selection unit 303 is a numerical value (0 to 306) that is used to acquire a big hit determination random number. One numerical value in the range of (integer) is selected as the initial random number.

  More specifically, for example, when the selector 303 detects that the ram clear switch 217 is pressed together with the power switch after the power is supplied, 0, 1, 2,. An initial random number is selected from a numerical group that loops in the order of 1. The function of the selection unit 303 can be realized by the CPU 211, the ROM 212, and the RAM 213, for example.

  The storage unit 304 stores the initial value random number selected by the selection unit 303. The storage unit 304 stores, for example, the initial value random number selected by the selection unit 303 when it is detected that the ram clear switch 217 is pressed together with the power switch after power is supplied. The function of the storage unit 304 can be realized by the RAM 213, for example.

  The counting unit 305 counts a counter value related to acquisition of a jackpot determination random number. The count unit 305 starts counting from an initial value set by the control unit 308, for example, and counts for one loop. For example, when an operation signal is detected by the detection unit 302, the count unit 305 starts counting for one loop from the set initial value, and when the count is one loop, the initial value at the time of one loop is obtained. The next one loop is counted from the random number.

  More specifically, the count unit 305 counts 20, 21, 22,..., 306, 0, 1,... 19 when counting for one loop is started from 20, for example. To do. Then, when counting for the next one loop is started from 145, 145, 146, 147,..., 306, 0, 1,.

  The backup unit 306 generates backup data of game information during a game when the supply amount of power to the main control unit 210 is lower than a predetermined value. For example, the backup unit 306 generates backup data including all game information during the game. The generation of backup data will be described later (see FIG. 7).

  The game information during the game is, for example, the number of prize balls to be paid out, or the number of rounds if the game is a big hit. The game information during the game includes, for example, a jackpot determination random number, a count value for acquiring the jackpot determination random number, an initial value random number, a count value for acquiring the initial value random number, and initial value data. The storage unit 304 described above further stores the backup data generated by the backup unit 306.

  Further, when the generation of the backup data is normally completed, the backup unit 306 sets a flag indicating that the backup data is valid in association with the generated backup data. The storage unit 304 stores a flag indicating that the backup data is valid in association with the generated backup data. The function of the backup unit 306 can be realized by the CPU 211, the ROM 212, and the RAM 213, for example.

  The determination unit 307 determines the validity of the backup data generated by the backup unit 306 when power is supplied to the main control unit 210. For example, when the flag associated with the backup data is set, the determination unit 307 determines that the backup data is valid. In this case, the determination unit 307 determines that the backup data is invalid when there is no flag associated with the backup data. The determination unit 307 can realize its function by the CPU 211, the ROM 212, and the RAM 213, for example.

  The control unit 308 detects an initial value random number selected by the selection unit 303 (that is, stored in the storage unit 304) when an operation signal indicating that a predetermined operation has been performed after power supply is detected by the detection unit 302. The initial value random number) is set as the initial value of the counter value for obtaining the jackpot determination random number, and the game is started.

  Specifically, the control unit 308 waits for a start winning, for example, and when there is a starting winning, the control unit 308 acquires, as a jackpot determining random number, a counter value for acquiring the jackpot determining random number at the time of starting winning. This makes it possible to determine the jackpot.

  Specifically, the control unit 308 compares, for example, the acquired jackpot determination random number with the jackpot value, and determines whether or not the acquired jackpot random number matches the jackpot value. If the acquired jackpot random number matches the jackpot value, it is determined that the jackpot is a jackpot and a jackpot game is played (see FIG. 12).

  Further, specifically, the control unit 308 enables, for example, a game ball to be launched by the launch unit. As a result, a start win is generated and the above jackpot game can be performed. Furthermore, the control unit 308 specifically outputs a control signal that causes the symbol control unit 220 to perform an effect process, for example.

  Further, the control unit 308 initializes game information during the game when the backup data is invalid based on the determination result by the determination unit 307. When the backup data is invalid, the control unit 308 displays, for example, a jackpot determination random number, a count value for acquiring the jackpot determination random number, an initial value random number, a count value for acquiring the initial value random number, initial value data, and the like. Set all to 0 (zero). The control unit 308 can realize its functions by, for example, the CPU 211, the ROM 212, the RAM 213, and the I / O 216.

  When power is supplied to the main control unit 210, the output unit 309 outputs an abnormal effect start signal to the symbol control unit 220 until the ram clear signal is detected by the detection unit 302. The abnormality effect is performed, for example, by displaying an abnormality notification image for notifying that an abnormality has occurred in the gaming machine on the symbol display unit 104. The output unit 309 can realize its function by, for example, the CPU 211, the ROM 212, the RAM 213, and the I / O 216.

  Also, the abnormal presentation is performed by outputting a warning sound such as a siren from the lower bus SP271 or the upper stereo speaker 272, for example. Furthermore, the abnormality detection may be performed, for example, by blinking the decoration LED 261, the glass frame lamp 262, the side lamp 263, and the like in a predetermined pattern (can be turned on).

  The gaming machine performs all of an abnormality notification image display, alarm sound output, and blinking of various lamps as an abnormality effect. In addition, the gaming machine may perform any one or two of an abnormality notification image display, an alarm sound output, and various lamps blinking as an abnormality effect. For example, the gaming machine may display an abnormality notification image and output an alarm sound, output an alarm sound and blink various lamps, or display an abnormality notification image and various lamps as an abnormality effect. May blink.

(Processing procedure of the main control unit)
Next, a processing procedure of the main control unit 210 will be described. The main control unit 210 performs processing such as main substrate processing, main substrate processing (INT interrupt), and backup control processing. Here, the main substrate processing will be described. FIG. 4 is a flowchart showing a procedure of main substrate processing. In the flowchart of FIG. 4, first, power-on control processing is performed (step S401). Details of the power-on control process will be described later (see FIG. 8).

  Then, after the power-on control process, various output processes are performed (step S402). In step S402, as various output processes, for example, an image for activation is displayed on the symbol display unit 104, an alarm sound is output from the lower bus SP271 or the upper stereo speaker 272, the decoration LED 261, the glass frame lamp 262, the side A light emitter such as the lamp 263 is caused to emit light.

  Next, various non-interrupt control processes are performed (step S403). In step S403, processing other than the processing included in the main board processing (see FIG. 5) that performs INT interrupting is performed as processing outside interrupt processing, which is performed by the main control unit 210. Specifically, in step S403, for example, processing other than time control processing, random number control processing, special figure special power control processing, ordinary map power control processing, payout control processing, data creation processing, and output control processing is executed. .

  Next, the processing state of the main control unit 210 is disabled (step S404), the initial value random number is incremented by 1 with the interrupt disabled, and the initial value random number is updated (step S405). Then, it is determined whether or not the value of the initial random number updated by adding 1 is 307 or more (step S406).

  In this embodiment, as described above, an initial value random number is selected from a numerical group of 0 to 306. For this reason, in step S406, it is determined whether or not the initial value random number is 307 or greater, which is larger than the maximum value that can be taken. That is, in step S406, the numerical value used for comparison differs depending on the numerical value range used as the random number.

  If the updated initial random number value is less than 307 in step S406 (step S406: No), the process proceeds to step S408. On the other hand, when the updated initial value random number value is 307 or more in step S406 (step S406: Yes), it can be determined that the updated initial value random number value exceeds the maximum value that the initial value random number can take. Therefore, the value of the initial value random number is set to 0, which is the minimum value that the initial value random number can take (step S407). Thereafter, the interrupt disabled in step S404 is permitted (step S408), and the process returns to step S403. Thereafter, the processing from step S403 to step S408 is repeated.

  Next, main board processing for interrupting INT will be described. FIG. 5 is a flowchart showing a procedure of main board processing for performing INT interruption. The main board process for performing the INT interruption shown in FIG. 5 is executed by interrupting the power-on control process during the execution of the power-on control process shown in FIG. Further, the main board process for performing the INT interrupt is started separately from the power-on control process. Further, the main board process for interrupting INT is started every predetermined time (for example, 4 msec).

  As shown in the flowchart of FIG. 5, first, time control processing is executed (step S501), and then random number control processing is executed (step S502). Details of the time control process executed in step S501 and the random number control process executed in step S502 will be described later.

  After that, the special figure special electric control process, the ordinary figure electric power control process, the payout control process, the data creation process, and the output control process are performed in order (steps S503 to S507). Thereafter, when 4 msec has elapsed since the start of the main board process for interrupting the previous INT, the process returns to step S501 again to execute a series of processes. In addition, description is abbreviate | omitted here about the special figure special electric power control process, the ordinary figure electric power control process, the payout control process, the data creation process, and the output control process which are executed in steps S503 to S507.

  Next, the random number control process among the main board processes for performing the INT interrupt will be described. The random number control process is executed in the main board process for interrupting INT, which is started during the execution of the main board process shown in FIG. FIG. 6 is a flowchart showing a processing procedure of random number control processing. In FIG. 6, first, the count value for acquiring the jackpot determination random number in the RAM 213 is incremented by one (the count value for acquiring the jackpot determination random number in FIG. 6 (described as “count value (random hit determination random number)” in FIG. 6). Is updated (step S601).

  Then, it is determined whether or not the count value for acquiring the jackpot determination random number updated by incrementing by 1 in step S601 is 307 or more (step S602). In this embodiment, as described above, a jackpot determination random number is acquired from a numerical group of 0 to 306. For this reason, in step S602, it is determined whether or not the value is 307 or greater, which is larger than the maximum value that can be taken by the count value for obtaining the jackpot determination random number. That is, in step S602, the numerical value used for comparison differs depending on the numerical value range used as a random number.

  In step S602, when the count value for obtaining the updated jackpot determination random number is less than 307 (step S602: No), the process proceeds to step S604. In this case, the numerical value updated by incrementing by 1 is stored in the RAM 213 as a count value for obtaining the jackpot determination random number.

  On the other hand, in step S602, when the count value for acquiring the updated jackpot determination random number is 307 or more (step S602: Yes), the count value for acquiring the updated jackpot determination random number is the jackpot determination random number. Since it can be determined that the maximum value that can be taken is exceeded, the count value for obtaining the big hit determination random number is set to 0, which is the minimum value that the big hit determination random number can take (step S603). In this case, 0 (zero) is stored in the RAM 213 as a jackpot determination random number.

  Next, it is determined whether or not the count value for acquiring the jackpot determination random number in the RAM 213 matches the initial value data (step S604). In step S604, when the count value for acquiring the jackpot determination random number in the RAM 213 does not match the initial value data (step S604: No), the series of random number control processing ends. In this embodiment, as shown in FIG. 5, after the random number control process is completed, the special figure special electric control process is started.

  On the other hand, in step S604, if the count value for acquiring the jackpot determination random number in the RAM 213 matches the initial value data (step S604: Yes), the initial value random number stored in the RAM 213 is used as the jackpot determination random number. Is set as the count value related to the acquisition of the jackpot, and the count value related to the acquisition of the jackpot determination random number is updated (step S605). As a result, the count value for obtaining the jackpot determination random number stored in the RAM 213 and the initial value random number become the same numerical value.

  As described above, the initial value random number stored in the RAM 213 is updated as needed at a time different from the count value for obtaining the jackpot determination random number. In step S605, the count value for acquiring the big hit determination random number is changed to the initial value random number stored in the RAM 213 when it is determined that the count value for acquiring the big hit determination random number in the RAM 213 matches the initial value data. Update.

  Next, the initial value data is updated to the initial value random number (step S606), and the series of random number control processing ends. As described above, since the initial value random number stored in the RAM 213 is updated at any time by the above-described processing of FIG. 4, in step S606, the jackpot determination random number stored in the RAM 213 is changed to the initial value data. The initial value data is updated by setting the initial value random number stored in the RAM 213 as the initial value data when it is determined that they match. In this embodiment, after the random number control process is completed, the special figure special power control process is started.

  Either step of the process of step S605 and the process of step S606 in FIG. 6 may be performed first. That is, in the present embodiment, the process of step S606 is described after the process of step S605. However, the process of step S605 can be performed after the process of step S606.

  Next, backup control processing will be described. FIG. 7 is a flowchart showing the procedure of the backup control process. In the backup control process, when there is a voltage drop signal indicating that the voltage value of the power supplied to the main control unit 210 has dropped below a predetermined voltage value, for example, the main board process shown in FIG. 4 is executed. This is an interrupt process that is interrupted. The backup control process is performed with priority over all processes performed by the main control unit 210. The backup control process starts at an arbitrary timing when there is a voltage drop signal.

  In the flowchart of FIG. 7, first, when there is a voltage drop signal, the backup valid flag is turned off (step S701). As a result, the RWM area checksum set for backup is invalidated. Then, the power-off process is performed (step S702). A description of the power-off process is omitted.

  Next, based on the gaming state of the gaming machine at the time when the power is turned off, a power-off RWM area checksum is created (step S703). By the processing in step S703, various data relating to the game at the time of turning off the power is stored in the RWM area. Thereafter, the backup valid flag is turned on (step S704), and the series of backup control processes is terminated. Thereby, various data relating to the game at the time of turning off the power is stored in a usable state.

  Next, the power-on control process will be described. FIG. 8 is a flowchart showing the procedure of the power-on control process. The power-on control process shown in FIG. 8 is performed in step S401 in the main board process shown in FIG. The power-on control process is executed when power is supplied to the main control unit 210.

  In the flowchart of FIG. 8, first, when power is supplied to the main control unit 210, the processing state of the main control unit 210 is disabled (step S801). Then, it is determined whether or not the level of the ram clear switch 217 is on (step S802). As described above, the level of the ram clear switch 217 is turned on while being pressed. When the level of the ram clear switch 217 is ON, that is, when the ram clear switch 217 is pressed (step S802: Yes), the process proceeds to step S806.

  In step S802, if the level of the ram clear switch 217 is not on, that is, if the ram clear switch 217 is not pressed (step S802: No), it is determined whether the backup data stored in the RAM 213 is valid. (Step S803).

  In step S803, it is determined whether a flag associated with the backup data is set (the backup valid flag is on). If the backup data is invalid, that is, if the flag associated with the backup data is not set (the backup valid flag is not on) (step S803: No), the process proceeds to step S806.

  If the backup data is valid in step S803 (step S803: Yes), a checksum is created in the power-on RWM area provided in the RAM 213 (step S804). Then, it is determined whether or not the checksum created in step S804 is equivalent to the backup data (step S805).

  If the checksum and backup data are not the same value in step S805 (step S805: No), the RWM area is initialized (step S806). Then, a power-on command is transmitted to the symbol control unit (sub-board) 220 (step S807). In this embodiment, the power-on command is a control signal for causing the symbol display unit 104 to display a message prompting the ram clear switch 217 to be operated again.

  When the power-on command is input, the symbol control unit 220 outputs image data for guiding the power-on to the symbol display unit 104. The symbol control unit 220 outputs image data for displaying a message such as “active”, for example. Further, the symbol control unit 220 outputs image data for displaying a message such as “Please operate the game start key”. As a result, the symbol display unit 104 displays messages 901 and 902 as shown in FIG.

  Accordingly, in the gaming machine, when power is supplied to the main control unit 210, the symbol control unit 220 performs an abnormal effect until the power switch and the ram clear switch 217 are pressed. As a result, it is possible to inform the customers around the gaming machine and the store clerk who visits the store that the cheating is being performed. And it can contribute to discovery of fraud and prevention of fraud.

  Next, the initial value random number stored in the RAM 213 is incremented by 1, and the initial value random number is updated (step S808). Then, it is determined whether or not the value of the initial random number updated by adding 1 is 307 or more (step S809). In this embodiment, as described above, an initial value random number is selected from a numerical group of 0 to 306. For this reason, in step S809, it is determined whether or not the value is 307 or greater, which is larger than the maximum value that the initial random number can take. That is, in step S809, the numerical value used for comparison differs depending on the numerical value range used as a random number.

  If the updated initial random number value is less than 307 in step S809 (step S809: No), the process proceeds to step S811. On the other hand, if the updated initial random number value is 307 or more in step S809 (step S809: Yes), it can be determined that the updated initial random number value exceeds the maximum value that the initial random number can take. Therefore, the value of the initial value random number is set to 0, which is the minimum value that the initial value random number can take (step S810).

  Then, it is determined whether or not the edge of the signal output from the ram clear switch 217 has been turned on (step S811). In step S811, when the ram clear switch 217 is operated, the signal output from the ram clear switch 217 is turned on, and it is detected that the edge is turned on. If the edge is not in the on state (step S811: No), the process returns to step S807, and a power-on command is transmitted to the symbol control unit 220.

  In step S811, when the edge of the signal output from the ram clear switch 217 is turned on (step S811: Yes), the initial value random number stored in the RAM 213 is set as a jackpot determination random number to determine the jackpot determination. The random number for use is updated (step S812). As a result, the jackpot determination random number stored in the RAM 213 and the initial value random number have the same numerical value.

  As described above, the initial value random number stored in the RAM 213 is updated at any time different from the jackpot determination random number. In step S812, the jackpot determination random number is updated to the initial value random number stored in the RAM 213 when it is determined that the counter value for obtaining the jackpot determination random number in the RAM 213 matches the initial value data.

  Thereby, after the operation of the ram clear switch 217 at the time of turning on the power, the initial value random number when the ram clear switch 217 is operated again is set as the initial value of the counter value for obtaining the jackpot determination random number. That is, the gaming machine starts counting the counter value for obtaining the jackpot determination random number from the initial value random number when the ram clear switch 217 is operated again.

  Specifically, for example, if the initial random number at the time when the ram clear switch 217 is operated again is 41, 41, 42,..., 306, 0, 1,. Specifically, for example, if the initial value random number at the time when the ram clear switch 217 is operated again is 304, 304, 305, 306, 0, 1,..., 303 are counted.

  Next, the initial value data is updated to an initial value random number (step S813). As described above, since the initial value random number stored in the RAM 213 is updated at any time by the above-described processing of FIG. 4, in step S813, the jackpot determination random number stored in the RAM 213 is changed to the initial value data. The initial value data is updated by setting the initial value random number stored in the RAM 213 as the initial value data when it is determined that they match. Thereafter, the interrupt disabled in step S801 is permitted (step S814), and the series of power-on control processing ends.

  In step S805, if the checksum and backup data have the same value (step S805: Yes), the power recovery processing is performed (step S815), and the series of power-on control processing ends. Description of the power recovery process is omitted here.

  Next, the start SW process will be described. The start SW process can be executed after the power-on control process shown in FIG. 8 is completed and the count value for obtaining the jackpot determination random number is started. FIG. 10 is a flowchart showing the procedure of the start SW process. The start SW process shown in FIG. 10 is executed every predetermined time (for example, 4 msec). In the flowchart of FIG. 10, first, it is determined whether or not the start SW 251 is turned on (step S1001).

  If the start SW 251 is turned on in step S1001 (step S1001: Yes), the edge counter is incremented by 1 (step S1002), and it is determined whether or not the value of the incremented edge counter is 2 (step S1003). ). If the incremented edge counter value is 2 (step S1003: Yes), the start winning signal is turned on (step S1004). Thereby, it is detected that there has been a start prize. Thereafter, the start SW process is exited, and the process starts again from step S1001 after 4 msec.

  On the other hand, if the start SW 251 is not turned on in step S1001 (step S1001: No), the value of the edge counter provided in the RAM 213 is set to 0 (zero) (step S1005). If the value of the edge counter incremented by 1 in step S1002 is not 2 (step S1003: No), the start SW process is exited as it is. Then, when 4 msec has elapsed since the start SW process was started last time, the process is started again from step S1001.

  FIG. 11 is an explanatory diagram showing changes in the output of the start SW 251. In FIG. 11, the vertical axis represents the change in the voltage signal, and the horizontal axis represents the passage of time. Further, in FIG. 11, a plurality of dotted lines indicate that a time of 4 msec has elapsed. As shown in FIG. 11, when the game ball passes through the start winning opening 105, the output of the start SW 251 is continuously turned on three times. The number of times the ON state continues is determined within a predetermined range depending on the size of the game ball. For this reason, when the output of the start SW 251 is continuously turned on four times, it is also possible to detect that an abnormality has occurred in the gaming machine, such as a game ball clogged in the start winning opening 105. It is.

  Next, the jackpot determination process will be described. The jackpot determination process can be executed after the power-on control process shown in FIG. 8 is terminated and counting of the count value for acquiring the jackpot determination random number is started. The jackpot determination process can be executed after the start SW process shown in FIG. 10 is completed and it is detected that there has been a start win.

  FIG. 12 is a flowchart showing the procedure of the jackpot determination process. In the flowchart of FIG. 12, first, it is determined whether or not there is a start winning (step S1201). In step S1201, it is determined whether or not there is a start winning based on the result of the start SW process shown in FIG. If there is no start prize (step S1201: No), the process proceeds to step S1205.

  In step S1201, when there is a start winning (step S1201: Yes), it is determined whether or not the number of reserved game balls that have been won is less than four (step S1202). Here, the reserved number is the number of game balls that have won the start. In other words, the reserved number indicates the number of times that the game ball has won the start winning opening 105 (start winning prize number). Specifically, the gaming machine stores the value of the jackpot determination random number acquired when the game ball is won for starting. The gaming machine stores the reserved number in a storage area provided in the RAM 213. The maximum number of reserves is four. That is, the gaming machine stores a jackpot determination random number for performing the jackpot determination for four times at maximum.

  In step S1202, when the number of reservations is 4 or more (step S1202: No), the process proceeds to step S1205. On the other hand, when the reserved number is less than 4 (step S1202: Yes), the jackpot determination random number is acquired as described above (step S1203). Then, the reserved number is incremented by 1 and the jackpot determination random number acquired in step S1203 is stored in a storage area provided in the RAM 213 (step S1204).

  Next, it is determined whether or not the number of holds stored in step S1204 is 1 or more (step S1205). When the number of reservations is not 1 or more (step S1205: No), the process returns to step S1201. When the number is 1 or more (step S1205: Yes), the value of the reserved number −1 is set as the reserved number, and the jackpot determination random number stored in step S1204 is compared with the jackpot value (step S1206). Then, based on the comparison result, it is determined whether or not the jackpot determination random number is a jackpot value (step S1207).

  In step S1207, when the jackpot determination random number is a jackpot value (step S1207: Yes), a jackpot game is played. In this embodiment, jackpot variation processing is performed (step S1208), and then the symbol is stopped (step S1209). Thereafter, the jackpot operation process is performed (step S1210), and the process returns to step S1201 to determine whether or not there is a start prize.

  Specifically, the processing in steps S1208 and S1209 is realized by outputting, for example, a control signal for playing a jackpot game to the symbol control unit 220. By the processing of steps S1208 and S1209, the symbol display unit 104 displays a symbol (for example, “777”) in which a predetermined symbol is changed and a symbol that reaches a reach is displayed after displaying a symbol that becomes a reach. Description of processing performed in the jackpot game such as jackpot variation processing and jackpot action processing is omitted here.

  On the other hand, if the jackpot determination random number is not a jackpot value in step S1207 (step S1207: No), a deviation variation process is performed (step S1211), and then the symbol is stopped (step S1212). By the process of step S1212, the symbol display unit 104 displays a symbol in a state where the three symbols are not aligned. The explanation of the deviation variation process is omitted here. Thereafter, the process returns to step S1201, and it is determined whether or not there is a start prize.

  As described above, according to this embodiment, when power is supplied, the initial value random number is continuously updated until the ram clear switch 217 is pressed. That is, the initial value random number continues to be updated from the time when power is supplied until the time when the ram clear switch 217 is pressed. The time interval from when the power is supplied to when the ram clear switch 217 is pressed is extremely difficult to make artificially constant. For example, the operation can be performed according to the sense of a store clerk operating the power switch. Different for each.

  As a result, the timing at which the supply of power is started can be made different from the timing at which the initial value random number is acquired. Thus, according to this embodiment, an illegal act of predicting the appearance timing of a specific numerical value from the outside of the gaming machine, acquiring the specific numerical value as a numerical value for jackpot determination, and performing a jackpot game at a high frequency Can be prevented.

  Further, according to this embodiment, the jackpot determination random number and the initial value random number can be obtained by using a predetermined number of numerical values. In other words, while predicting the appearance timing of specific numerical values from the outside of the gaming machine while suppressing the excessive amount of data used to acquire the jackpot determining random numbers and initial value random numbers, determine the specific numerical value It is possible to prevent fraudulent acts that are obtained as numerical values for use and play jackpot games at a high frequency.

  According to this embodiment, when power is supplied, the initial value random number is selected when the power switch and the ram clear switch 217 are not pressed separately from the operation for supplying power. In other words, the counting of the counter value for obtaining the jackpot determination random number is not started.

  For this reason, for example, a state where both the count value of the jackpot determination random number and the initial value random number are set to 0 (zero) via an unauthorized board connected to the main control unit (main board) 210 is illegally generated, and power is supplied. The timing at which the power supply is started is different from the timing at which the counting of the counter value for obtaining the jackpot determination random number is started. The appearance timing cannot be predicted.

  Accordingly, it is possible to prevent an illegal act of predicting the appearance timing of a specific numerical value from the outside of the gaming machine, acquiring the specific numerical value as a big hit determination random number, and playing the big hit game at a high frequency.

  In addition, according to this embodiment, since the signal output by performing the same process as the normal ram clear, that is, pressing the power switch and the ram clear switch 217 is detected, for example, an employee of a pachinko hall, etc. The above effect can be obtained by simply repeating the key operation during ram clear.

  As a result, for example, an employee can add a light burden that repeats the same operation in addition to a ram clear operation when the power is turned on (in this embodiment, a pressing operation of the power switch and the ram clear switch 217). By predicting the appearance timing of a specific numerical value from the outside of the gaming machine and using the specific numerical value as a random number for jackpot determination, it is possible to prevent fraudulent acts that cause a jackpot game to be played at a high frequency.

  In addition to the operation for supplying power, the initial value random number is selected when the power switch and the ram clear switch 217 are pressed twice or more, and the counter value for obtaining the jackpot determination random number is counted. You may make it start. In this case, it is preferable that the number of pressing operations, for example, the operation burden added to an employee or the like is a slight one that is not significantly different from normal power-on. Also by this, it is possible to prevent a fraudulent act of playing a jackpot game at a high frequency by predicting the appearance timing of a specific number from the outside of the gaming machine and using the specific number as a random number for jackpot determination.

  Further, the operation for selecting the initial value random number and starting the counting of the counter value for obtaining the jackpot determination random number is not limited to the pressing operation of the power switch and the ram clear switch 217, but is another operation. Also good. In this case, it is preferable that another operation does not excessively increase the burden on the employee or the like, for example, and does not greatly differ from normal power-on. Also by this, it is possible to prevent a fraudulent act of playing a jackpot game at a high frequency by predicting the appearance timing of a specific number from the outside of the gaming machine and using the specific number as a random number for jackpot determination.

  Further, according to this embodiment, when a situation occurs in which the amount of power supply to the main control unit 210 falls below a predetermined value, such as during a power failure, backup data of game information during the game is generated. If the backup data when the power is supplied to the main control unit 210 is invalid, information used for acquiring the jackpot determination random number such as an initial value random number or initial value data is initialized.

  Also in this case, the game cannot be started unless the power switch and the ram clear switch 217 are pressed. That is, when the power supply is shut off and supplied by a signal output from an unauthorized board connected to the main controller 210, the power switch and the ram clear switch 217 cannot be pressed after the power supply is started. The subsequent game can be stopped.

  Accordingly, it is possible to prevent an illegal act of predicting the appearance timing of a specific numerical value from the outside of the gaming machine, acquiring the specific numerical value as a big hit determination random number, and playing the big hit game at a high frequency.

  As described above, the main control board, the gaming machine, and the program according to the present invention relate to a gaming machine such as a pachinko machine, and in particular, a numerical value for jackpot determination acquired for each winning of the start opening and a predetermined numerical value.
