Description

The present invention relates to a gaming machine such as a pachinko gaming machine, and more specifically, based on the fact that the variable display start condition is satisfied after the variable display execution condition is satisfied, a plurality of types of identification information that can identify each of the identification information is provided. The present invention relates to a gaming machine that includes a variable display device that variably displays and controls a specific gaming state that is advantageous for a player when the display result of the variable display becomes a predetermined specific display result.

  In gaming machines such as pachinko machines, variable display is performed by updating and displaying predetermined identification information (hereinafter referred to as display symbols) on a display device such as a liquid crystal display (hereinafter referred to as LCD). There are provided a number of games that are enhanced by a so-called variable display game that determines whether or not to give a predetermined game value based on a display result that is a combination result.

  Some variable display games are played by using the above-described display device as an image display device (hereinafter referred to as a special game). The special figure game is based on the detection of the game ball passing through the start winning opening (the start condition of the variable display is established), and the display design is updated and the display design update display is completely stopped. A game in which the case where the stop symbol form is a predetermined specific display form is “big hit”. Whether or not it is a “big hit” in the special game is determined by whether or not the random number value read from the random counter or the like matches a predetermined big hit judgment value. Alternatively, a special electric accessory called an attacker is opened, and a state in which winning of a game ball is extremely easy for a player is continuously provided for a certain period of time.

Conventionally, a random number for determining whether or not to make a “big hit” (hereinafter referred to as a big hit determination random number) is generated by a random number circuit externally attached to a game control microprocessor (for example, a patent) The counter unit 62) described in Document 1. In addition, a technique in which a microprocessor generates a random number using an application program has been proposed (for example, Patent Document 2).
JP 2000-300183 A. JP 2002-282457 A.

  However, in the configuration of Patent Document 1, a circuit for generating random numbers must be arranged separately from the microprocessor, which increases the amount of hardware and occupies board space. Further, since the random number circuit of Patent Document 1 only counts the output of the pulse generator, there is a possibility that the randomness such as the periodicity of the generated random number may be lowered.

  In the technique described in Patent Document 2, a microprocessor generates a random number by software processing. Therefore, no hardware is required other than the microprocessor. However, since the program generates random numbers, the processing load on the microprocessor is large. In particular, because a random number update process is performed during the execution of a timer interrupt process for game control, it is necessary to develop a program similar to that for game control, and a random number for a limited interrupt processing time. There has been a problem that processing for generation has to be started and ended, increasing the processing load on the microprocessor.

  In addition, since the count value of the counter is periodically counted up, a random number value that matches the jackpot determination value is generated when the count-up cycle or the cycle in which the counter count value makes one round is detected by any means. Timing is recognized. Then, it is possible to frequently generate “hit” by playing a game aimed at the timing at which a random number value that matches the jackpot determination value is generated. In some cases, an illegal board is attached to a gaming machine in order to aim at a timing at which a random number value that matches the jackpot value is generated. Such a fraudulent board introduces a signal output to the outside from the circuit part that performs game control, detects the start timing of the circuit part that performs game control based on the signal, and the random value that matches the jackpot determination value is The timing of occurrence is detected. Then, the illegal board can send a predetermined signal to the circuit portion that controls the game at that timing, and illegally generate a “big hit”. As a result, there is a disadvantage in the game store where the gaming machine is installed.

  The count value permutation change circuit 123 includes a count value permutation change register (RSC) 133 that stores count value permutation change data “01h” for requesting a change in permutation that is the count value update order, and an update rule selection register (RRC). 141 and an update rule memory 142. When the numerical value permutation change data “01h” is stored in the count value permutation change register, the count value permutation change circuit 123 changes the permutation to be different from the permutation when the count value permutation change data “01h” is not stored. To do.

  FIG. 5 is a block diagram illustrating a configuration example of the update rule selection register 141. As shown in FIG. 5, the update rule selection register 141 is an 8-bit register, and its initial value is set to “0 (= 00h)”. The update rule selection register 141 is configured so that bits 0 to 3 can be written and read, and bits 4 to 7 cannot be written and read. Therefore, even if a value is written in bit 4 to bit 7 of the update rule selection register 141, the value is invalid, and all the values read from bit 4 to bit 7 are “0 (= 0000b)”.

  In response to the count value permutation change data “01h” being written in the count value permutation change register 133, the value (register value) of the update rule selection register 141 is changed from “0 (= 00h)” to “15 (= 0Fh) ”is updated cyclically. That is, each time the count value permutation data “01h” is written to the count value permutation change register 133, the register value is incremented from “0” by “1”, and when it becomes “15”, it returns to “0” again.

  FIG. 6 is a block diagram illustrating a configuration example of the update rule memory 142. As illustrated in FIG. 6, the update rule memory 142 stores the count value update rule and the value of the update rule selection register 141 in association with each other. In the update rule memory 142, the same update rule A as the update rule of the counter 121 is stored in correspondence with the register value “0”, and the update rules B to P different from the update rule of the counter 121 have the register value “1”. To "15".

  When the count value permutation change data “01h” is written in the count value permutation change register 133, the count value permutation change circuit 123 shown in FIG. 4 receives the final count value “4095” from the counter 121. Based on the updated register value, the update rule of the count value to be output is switched by selecting and setting the update rule from the update rule memory 142. In response to the input from the counter 121, the count value permutation changing circuit 123 updates and outputs the count value according to the switched update rule.

  In this way, the count value permutation changing circuit 123 switches the update rule in response to the count value permutation change data “01h” being written in the count value permutation change register 133, thereby outputting the permutation of the count values to be output. To change.

  FIG. 7 is an explanatory diagram of the operation of changing the count value permutation in the count value permutation changing circuit 123. As shown in FIG. 7, when the count value permutation change data “01h” is written to the count value permutation change register 133 at a predetermined timing by the CPU 106, the register value is incremented by 1, for example, from “0” to “1”. Updated. Thereafter, the count value permutation changing circuit 123 updates the count value according to the “update rule A” corresponding to the register value “0” before the update until the final value “4095” of the count value is input from the counter 121. Output. At this time, the permutation of count values output from the count value permutation changing circuit 123 is “1 → 2 →... → 4095”.

  When the final value “4095” of the count value is input from the counter 121, the count value permutation changing circuit 123 stores “update rule B” corresponding to the updated register value “1” from the update rule memory 142. Select and set. In response to the input from the counter 121, the count value permutation changing circuit 123 updates and outputs the count value in accordance with the “update rule B” selected and set. Thereby, the permutation of the count values output from the count value permutation changing circuit 123 is changed from “1 → 2 →... → 4095” to “4095 → 4094 →.

  Thereafter, the count value permutation change register 133 is initialized as will be described later, and the permutation of count values output from the count value permutation change circuit 123 remains “4095 → 4094 →... → 1”.

  When the count value permutation change data “01h” is written again to the count value permutation change register 133 by the CPU 106, the register value is updated from “1” to “2”. When the final count value “4095” is input from the counter 121, the count value permutation changing circuit 123 selects the “update rule C” corresponding to the register value “2” from the update rule memory 142. Set. In response to the input from the counter 121, the count value permutation changing circuit 123 updates and outputs the count values according to the “update rule C” selected and set, thereby further changing the permutation of the count values, "1 → 3 → ... → 4095 → 2 ... → 4094".

  As described above, after the count value permutation change register 133 is initialized, the count value permutation data “01h” is written again into the count value permutation change register 133, so that the permutation of the changed count value can be further changed. .

  FIG. 8 is a diagram illustrating a configuration example of the count value permutation change register 133. As shown in FIG. 8, the count value permutation change register 133 is a readable 8-bit register, and its initial value is set to “0 (= 00h)”. The count value permutation change register 133 is configured so that only bit 0 is writable and writable. Therefore, even if a value is written to bit 1 to bit 7, the value is invalid, and bit 1 to bit 7 All the values read from “0” are “0 (= 0000000b)”.

  In response to the count value permutation change circuit 123 starting the count value update operation in accordance with the switched update rule, the CPU 106 counts the count value permutation change register 133 in which the count value permutation change data “01h” is written. Is initialized and the stored value is returned to the initial value “0 (= 00h)”.

  The comparator 122 includes a random number maximum value setting register (RMX) 132 that stores random number maximum value setting data that specifies the maximum value of random R (random number maximum value). The comparator 122 regulates the update range of the count value by the counter 121 according to the random number maximum value setting data stored in the random number maximum value setting register 132. In this embodiment, the random number maximum value (for example, “255”) designated by the count value input from the counter 121 and the random number maximum value setting data (for example, “00FFh”) stored in the random number maximum value setting register 132. When the input count value is less than or equal to the random number maximum value, the input count value is output to the random value register 131. When the input count value is greater than the random number maximum value, the count value update signal is Output to the counter 121.

  FIG. 9 is an explanatory diagram of a count value update operation in the counter 121 and the comparator 122. FIG. 9 illustrates an example in which the update rule A is selected in the count value permutation changing circuit 123 and the maximum random number is set to “255”.

  When the input count value is “1” to “255”, the comparator 122 outputs the input count value to the random value register 131 as it is. When the input count value becomes a value “256” larger than the random number maximum value “255”, the comparator 122 outputs a count value update signal to the counter 121 to update the count value to “257”. By repeating such an operation, the comparator 122 continuously counts up the input count value from “256” to “4095” by the counter 121. When the counter 121 counts up to “4095”, it outputs a notification signal to that effect to the CPU 106.

  When the initial value changed by the CPU 106 in response to the notification signal is larger than the random number maximum value “255” (for example, “256”), the counter 121 outputs the count value of the changed initial value to the comparator 122. The comparator 122 outputs a count value update signal to the counter 121 to update the count value. By repeating such an operation, the comparator 122 causes the counter 121 to continuously count up the input count value to “4095” and cause the counter 121 to output a notification signal. Then, the initial value is further changed by the CPU 106 responding to the notification signal. In this way, the initial value is changed until it becomes a value equal to or less than the maximum random number. When the initial value changed by the CPU 106 in response to the notification signal is equal to or less than the random number maximum value “255” (for example, “15”), the counter 121 compares the count value of the changed initial value with a comparator. The comparator 122 outputs the input count value to the random value register 131 as it is.

  By the operation of the counter 121 and the comparator 122 described above, the random number circuit 103 outputs only the count value less than or equal to the random number maximum value stored in the random number maximum value setting register 132 to the random number value register 131, so that the random number circuit 103 It is possible to generate a random R with the maximum random number “255” stored in the value setting register 131 as an upper limit. Further, by changing the initial value until the initial value becomes equal to or smaller than the random number maximum value, a value equal to or smaller than the random number maximum value “255” is input to the random value register 131 as the changed initial value.

As shown in FIG. 10, the random number maximum value setting register 132 is a 16-bit register, and its initial value is set to “4095 (= 0FFFh)”. The random number maximum value setting register 132 is configured such that bits 0 to 11 are writable and readable, and bits 12 to 15 are not writable and readable. Therefore, even if a value is written in bit 12 to bit 15 of the random number maximum value setting register 132, the value is invalid, and all the values read from bit 12 to bit 15 are “0 (= 0000b)”.

  When random number maximum value setting data “0000h” to “0003h” for designating a value smaller than the lower limit “4” is written in the random number maximum value setting register 132, the CPU 106 stores the random number maximum value setting register 132 in the random number maximum value setting register 132. The random number maximum value setting data “0FFFh” designating the initial value “4095” is stored. That is, the maximum random number value that can be set in the random number maximum value setting register 132 is from “4” to “4095”. The CPU 106 controls the random number maximum value setting register 132 in which the random number maximum value setting data is written to be unwritable until the game controller microprocessor 100 is system reset by the reset controller 102.

As shown in FIG. 12, the random value register 131 is a non-writable 16-bit register, and its initial value is set to “0001h”. The random value register 131 is configured such that bits 0 to 11 can be read and bits 12 to 15 cannot be read. Therefore, all the values read from bit 12 to bit 15 of the random value register 131 are “0 (= 0000b)”.

  The random number circuit activation signal output circuit 130 shown in FIG. 4 includes a random number circuit activation register (RST) 140 that stores random number circuit activation data “80h” for requesting activation of the random number circuit 103.

The CPU 106 executes the random number maximum value setting module 151a, and writes the random number maximum value setting data for specifying the maximum value of the random R preset by the user into the random number maximum value setting register 132. The maximum value of the random R is set in the random number circuit 103. For example, when the maximum value of the random R preset by the user is “255”, the CPU 106 writes the random number maximum value setting data “00FFh” in the random number maximum value setting register 132 and the random R maximum value “255”. Is set in the random number circuit 103.

The initial value is changed to a value set on the basis of an ID (Identification) number unique to the game control microprocessor 100.

  When initial value change method setting data “02h” for designating the second initial value change method is stored in the area of the user program execution data area at address 1F97h, the CPU 106 addresses address 1F97h in the user program execution data area. The designated RAM address is specified from the address data stored in the area, the value stored in the area of the specified designated RAM address is read, and the initial value is changed to the read value.

  When initial value change method setting data “03h” for designating the third initial value change method is stored in the area of address 1F97h in the user program execution data area, the CPU 106 stores the values stored in the respective addresses of the RAM 105. And the read value is added. Then, the CPU 106 changes the initial value to this added value.

This is a memory for storing a pending state in which a condition (start condition) for actually starting variable display is not satisfied due to reasons such as being executed. The special figure holding memory 170 includes four entries, and each entry has a holding number and a random R value read from the random number register 131 in accordance with the winning order in the order of winning in the normal variable winning ball apparatus 6. Are stored in association with each other. Each time the special symbol confirmation command is sent from the main board 11 to the display control board 12 and the special symbol variable display is finished once or the big hit gaming state is finished, the variable display based on the highest level information is performed. The start condition is satisfied, and variable display based on the highest level information is executed. At this time, the second and lower registration information is moved up by one place. Further, when a game ball newly wins the normal variable winning ball apparatus 6 during variable display of a special symbol or the like, the random R value read from the random value register 131 based on the winning is the highest empty.

Specifically, the jackpot determination table memory 171 stores a normal jackpot determination table 171a shown in FIG. 21A and a probability change jackpot determination table 171b shown in FIG. 21B.

  The normal big hit determination table 171a shown in FIG. 21 (A) and the probability variation big hit determination table 171b shown in FIG. 21 (B) indicate whether or not the display result of the special figure game by the variable display device 4 is a big hit. It is a table for judging. In each jackpot determination table 171a, 171b, the value of random R and setting data indicating the display result of the special figure game are stored in association with each other. In the probability change big hit determination table 171b, more random R values are associated with the display result of “big hit” than in the normal time big hit determination table 171a. That is, by determining the display result of the special figure game using the probability change jackpot determination table 171b, it is possible to achieve a probability improvement state in which the probability of becoming a jackpot gaming state is higher than that in the normal gaming state.

  In the flag memory 172 shown in FIG. 20, various flags used for controlling the progress of the game in the pachinko gaming machine 1 are set. For example, the flag memory 172 is provided with a special symbol process flag, a normal symbol process flag, a big hit state flag, an input state flag, a timer interrupt flag, an initial value change flag, and the like.

  The special symbol process flag indicates which process should be selected and executed in the special symbol process (FIG. 26) described later. The normal symbol process flag indicates which process should be selected and executed in a predetermined normal symbol process in order to control the display state of the normal symbol display 40 in a predetermined order. The big hit state flag is set to the on state when the display result of the special figure game by the variable display device 4 is a big hit, and is cleared to the off state when the big hit gaming state is finished.

  The input state flag is a flag composed of a plurality of bits that are set or cleared in accordance with the state of various signals input to the I / O port 108, the state of the detection signal input from each winning prize switch 70, and the like. The timer interrupt flag is set to the on state every time a predetermined time elapses and a timer interrupt is generated. The initial value change flag is set to an on state in response to the notification signal output from the random number circuit 103, and is cleared to an off state when the initial value is changed.

  The switch circuit 109 shown in FIG. 3 takes in the detection signal from each winning opening switch 70 and transmits it to the game control microprocessor 100. The solenoid circuit 110 drives the solenoids 21 and 22 in accordance with a command from the game control microprocessor 100. The solenoid 21 is connected to the movable wing piece of the normally variable winning ball apparatus 6 through a link mechanism. The solenoid 22 is connected to the opening / closing plate of the special variable winning ball apparatus 7 through a link mechanism.

  The display control board 12 is for performing effect control according to the control command received from the main board 11. Specifically, the display control board 12 performs display control of the variable display device 4 and lighting control of the game effect lamp 9 and the normal symbol display 40.

  The audio control board 13 and the lamp control board 14 are sub-side control boards that execute audio output control and lamp output control independently of the main board 11 based on control commands transmitted from the main board 11. is there. The payout control board 15 performs payout control for game balls, prize balls, and the like. The information terminal board 16 is for outputting various game-related information to the outside.

When the power to the pachinko gaming machine 1 is turned on, the game control main process is started. First, the CPU 106 sets the interrupt prohibition (step S1), and then sets the interrupt mode to mode 2 (step S1). S2).

  Thereafter, the CPU 106 sets a stack pointer designation address in the stack pointer (step S3). Then, a register setting such as CTC 107 which is a built-in device of the main board 11 of the game control microprocessor 100 is performed (step S4). For example, an interrupt vector is set for the CTC 107.

  Subsequent to step S4, the CPU 106 checks, for example, a backup flag area provided in the RAM 105 (step S5), and all or part of the RAM 105 is backed up by a predetermined data protection process when the power is last turned off. It is determined whether or not (step S6). In the pachinko gaming machine 1, when an unexpected power failure occurs, a data protection process for protecting all or a part of the data stored in the RAM 105 is performed. If such data protection processing has been performed, it is determined that there is a backup.

  When it is determined in step S6 that there is a backup (step S6; Yes), the CPU 106 performs a parity check as a backup data check, and determines whether the check result is normal (step S7). If the check result is normal (step S7; Yes), the internal state of the main board 11 and the control boards on the sub side (display control board 12, voice control board 13, lamp control board 14, and payout control board 15). A game state restoration process for returning the control state to the state at the time of power-off is executed (step S8). Then, it progresses to step S10.

  When it is determined in step S6 that there is no backup (step S6; No), or when the check result is not normal in step S7 (step S7; No), the CPU 106 clears the RAM 105 or performs a predetermined work area. Initialization processing such as initial setting is performed (step S9).

  Subsequently, the CPU 106 executes the random number circuit setting program 151 to perform random number circuit setting processing (step S10). In this random number circuit setting process, the random number circuit 103 is set to update the random R value.

  FIG. 23 is a flowchart showing the random number circuit setting process in step S10. In this random number circuit setting process, the CPU 106 first executes a random number maximum value setting module 151a included in the random number circuit setting program 151, and sets random number maximum value setting data for specifying a random number maximum value preset by the user as a random number. By writing in the maximum value setting register 132, the preset maximum value of the random R is set in the random number circuit 103 (step S21).

  Thereafter, the CPU 106 executes the random number circuit activation module 151d included in the random number circuit setting program 151, and writes the random number circuit activation data “80h” in the random number circuit activation register 140, thereby activating the random number circuit 103 (step S1). S22).

  Following the random number circuit setting process in step S10, the CPU 106 performs setting for timer interruption by the CTC 107 (step S11). Specifically, the timer mode is set by giving interrupt permission to one of a plurality of channels included in the CTC 107 (specifically, the third channel from the 0th channel to the third channel) of the CTC 107. And specify the initial count value for the channel. Thereby, thereafter, an interrupt request signal is sent from the CTC 107 to the CPU 106 every predetermined time (for example, 2 milliseconds), and the CPU 106 can periodically execute a timer interrupt process.

  Thereafter, the CPU 106 proceeds to a loop process for monitoring whether or not a timer interrupt has occurred due to an interrupt request signal from the CTC 107. In this loop process, after setting the interrupt prohibition (step S12), the display random number update process (step S13) is executed, and when the display random number update process is completed, the interrupt permission is set (step S14).

  When the CPU 106 that has executed the game control main process shown in FIG. 22 receives the interrupt request signal from the CTC 107 and accepts the interrupt request, the CPU 106 starts executing the game control interrupt process shown in FIG.

  When the game control interrupt process is started, the CPU 106 executes a predetermined power-off process, thereby making it possible to execute a predetermined data protection process or the like when the power supplied from the power supply board 10 is reduced (step) S101). Subsequently, by executing a predetermined switch process, the state of the detection signal input from each winning port switch 70 is determined (step S102).

  Next, the CPU 106 executes a display random number update process (step S103). Subsequently, the CPU 106 executes the initial value change program 153 to perform an initial value change process (step S104).

  FIG. 25 is a flowchart showing the initial value changing process in step S104. In this initial value change process, the CPU 106 first checks an initial value change flag provided in the flag memory 172 to determine whether or not a notification signal is output from the random number circuit 103 (step S171). When the initial value flag is in the off state (step S171; No), it is determined that the count value of the counter 121 has not been counted up to the final value, and the initial value changing process is terminated. On the other hand, if the initial value flag is on (step S171; Yes), the initial value change method setting data stored in the area 1F97h in the user program execution data area is read and the initial value change selected by the user is read. A method is specified (steps S172, S173, and S174).

  When initial value change method setting data “01h” for designating the first initial value change method is stored (step S172; Yes), the CPU 106 sets the initial value as an ID (Identification) unique to the game control microprocessor 100. The value is changed to a value set based on the number (step S175).

  When initial value change method setting data “02h” for designating the second initial value change method is stored (step S172; No, step S173; Yes), the CPU 106 stores the area 1F97h in the user program execution data area. The specified RAM address is specified from the RAM address data stored in the memory, and the value stored in the area of the specified specified RAM address is read (step S176). Then, the CPU 106 changes the initial value to the read value (step S177).

  When the initial value change method setting data “03h” for designating the third initial value change method is stored (step S172; No, step S173; No, step S174; Yes), the CPU 106 at each address of the RAM 105. The stored value is read (step S178), and the read value is added (step S179). Then, the CPU 106 changes the initial value to this added value (step S180).

  If it is determined No in step S172, step S173, and step S174, the initial value change method setting data stored in the area 1F97h in the user program execution data area is determined as “00h”, and the initial value is set. Without changing, the process proceeds to step S181.

  Thereafter, the CPU 106 clears the initial value change flag to turn it off (step S181), and ends the initial value change process.

  Subsequently, the CPU 106 executes the count value permutation change program 154 to perform a count value permutation change process (step S105). In this count value permutation update process, the CPU 106 changes the permutation of the count values input to the random value register 131 by writing the count value permutation change data “01h” into the count value permutation change register 133.

  Then, the CPU 106 executes the random value update program 155 to perform a random value update process (step S106). In this random number value update process, the CPU 106 writes the count value update data “01h” into the count value update register 135 to update the random R value stored in the random value register 131.

  Subsequently, special symbol process processing is executed (step S107). In the special symbol process, the corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to the gaming state. The value of the special symbol process flag is updated during each process according to the gaming state.

  Further, the CPU 106 executes normal symbol process processing (step S108). In the normal symbol process, the corresponding process is selected and executed according to the normal symbol process flag for controlling the normal symbol display 40 in a predetermined order. The value of the normal symbol process flag is updated during each process according to the gaming state. Further, the special symbol command control process (step S109) and the normal symbol command control process (step S110) are sequentially executed. Thus, the CPU 106 sends a display control command from the main board 11 to the display control board 12 to instruct display control of the variable display device 4 and lighting control of the normal symbol display 40.

  Subsequently, the CPU 106 executes predetermined information output processing to output various output data to each output port included in the I / O port 108 (step S111). In this information output process, a command for outputting jackpot information, starting information, probability variable information, etc. to the hall management computer is also sent from the main board 11 to the information terminal board 16.

  Further, the CPU 106 executes predetermined prize ball processing to set the number of prize balls based on the detection signal input from each winning opening switch 70 and outputs a payout control command to the payout control board 15. It is possible (step S112). Further, the CPU 106 performs a predetermined solenoid output process to open and close the movable wing piece in the normal variable winning ball device 6 and the open / close plate in the special variable winning ball device 7 when a predetermined condition is satisfied ( Step S113).

  FIG. 26 is a flowchart showing the special symbol process executed in step S107. When the special symbol process is started, the CPU 106 first executes the display result determination program 152 to determine whether or not the game ball has won the normal variable winning ball apparatus 6 and is included in each winning opening switch 70. A determination is made by checking a detection signal input from the detection switch, an input state flag provided in the flag memory 172, and the like (step S121). When the game ball is won and the detection signal from the start ball detection switch is turned on (step S121; Yes), the winning process is executed (step S122), and when the game ball is not won (step S121; No), the winning process is skipped.

  FIG. 27 is a flowchart showing the winning process in step S122. In this winning process, the CPU 106 first determines whether or not the starting winning memory number stored in the special figure reservation memory 170 is the maximum value “4” (step S141). Here, when the value of random R corresponding to the start winning memory number “4” is stored in the special figure holding memory 170, it is determined that the start winning memory number is “4”.

  When the start winning memory number is “4” (step S141; Yes), the start detection by the current winning is invalidated and the winning process is ended as it is. On the other hand, when the start winning memory number is less than “4” (step S141; No), the random R value is read from the random value register 131 (step S142), and the read random R value is provided in the RAM 105, for example. After storing in the predetermined buffer area (step S143), “1” is added to the start winning memory number (step S144). Then, the CPU 106 sets the random R value stored in the predetermined buffer area at the head of the empty entry in the special figure reservation memory 170 (step S145).

  Thereafter, the CPU 106 selects one of the nine processes of steps S130 to S138 shown in FIG. 26 based on the value of the special symbol process flag stored in the flag memory 172. Below, each process of step S130-S138 is demonstrated.

  The special symbol normal process of step S130 is a process executed when the value of the special symbol process flag is the initial value “0”. In this process, the CPU 106 determines whether or not the number of reserved memories stored in the special figure reservation memory 170 is “0”. Here, in the special figure hold memory 170, when various data such as the value of the random R1 corresponding to the hold number “1” is not stored, it is determined that the hold storage number is “0”. If the reserved storage number is “0”, the special symbol normal process is terminated by displaying a demonstration screen on the variable display device 4 via the display control board 12. On the other hand, if it is determined that the number of reserved memories is not “0”, the value of the special symbol process flag is updated to “1” which is a value corresponding to the big hit determination process.

  The jackpot determination process in step S131 is a process executed when the value of the special symbol process flag is “1”. In this process, as shown in FIG. 28, the CPU 106 first reads the random R value stored in correspondence with the hold number “1” from the special figure hold memory 170 (step S151). At this time, 1 is subtracted from the reserved storage number, and the value of the random R stored in the second to fourth entries (holding numbers “2” to “4”) of the special figure holding memory 170 is increased by one entry. Shift (step S152).

  Subsequently, the CPU 106 determines whether or not the probability improvement state (probability change is in progress) (step S153). If the probability change is not in progress (step S153; No), the CPU 106 determines that the game is in the normal game state and the special game. As a table for determining whether or not the display result is a big hit, a normal big hit determination table 171a as shown in FIG. 21A is set (step S154). On the other hand, if the probability change is in progress (step S153; Yes), a probability change big hit determination table 171b as shown in FIG. 21B is set (step S155).

  Based on the random R value read in step S151, the CPU 106 determines whether or not to display the special game display result as a big hit using the big hit determination table 171a or 171b set in step S154 or S155 ( Step S156). If it is decided to win the game (step S156; Yes), the big game status flag provided in the flag memory 172 is set to the on state (step S157), and if it is decided to be lost. (Step S156; No), the big hit state flag is cleared and turned off (Step S158). Thereafter, the value of the special symbol process flag is updated to “2” which is a value corresponding to the fixed symbol determination process (step S159).

  The confirmed symbol determination process in step S132 shown in FIG. 26 is a process executed when the value of the special symbol process flag is “2”. In this processing, the CPU 106 determines whether or not the big hit state flag provided in the flag memory 172 is on, and determines whether or not to reach based on the result of extracting a predetermined reach determination random number or the like. Is determined. According to these determination results, a final fixed symbol in the special figure game by the variable display device 4 is set. Thereafter, the value of the special symbol process flag is updated to “3” which is a value corresponding to the variable display pattern setting process.

  The variable display pattern setting process of step S133 is a process executed when the value of the special symbol process flag is “3”. In this process, the CPU 106 first determines whether or not the big hit state flag provided in the flag memory 172 is turned on, and whether or not it is determined to reach in the determined symbol determination process in step S132 above. Is determined, and a predetermined variable display pattern table is set according to these determination results. Then, based on the result of extracting the predetermined variable display pattern determination random number, etc., the variable display pattern to be used in the current special figure game is determined from the set variable display pattern table. After determining the variable display pattern in this way, the CPU 106 updates the value of the special symbol process flag to “4”, which is a value corresponding to the variable display command process.

  The variable display command process in step S134 is a process executed when the value of the special symbol process flag is “4”. In this process, the CPU 106 controls the variable display device 4 to start variable display for all the special symbols. Specifically, control data corresponding to the fixed symbol of the special symbol determined in the fixed symbol determination process in step S132 described above, or control data corresponding to the variable display pattern determined in the variable display pattern setting process in step S133 Is set in a predetermined command transmission table so that the variable display start command and the left / middle / right symbol designation command can be sent to the display control board 12. Then, the total variable display time corresponding to the variable display pattern is set in a predetermined variable display time timer, a variable display start command is transmitted, and countdown is started. Thereafter, when the predetermined variable display time timer times out, the value of the special symbol process flag is updated to “5” which is a value corresponding to the variable display stop process.

  The variable display stop process in step S135 is a process executed when the value of the special symbol process flag is “5”. In this process, the CPU 106 performs settings for sending a special symbol confirmation command from the main board 11 to the display control board 12. Specifically, the special symbol confirmation command is set to be able to be sent to the display control board 12 by setting control data corresponding to the special symbol confirmation command in a predetermined command transmission table. Further, when the pachinko gaming machine 1 is in the probability improved state, it is determined whether to return from the probability improved state to the normal gaming state, and if it is determined to return, the gaming state in the pachinko gaming machine 1 is changed from the probability improved state to the normal state. Transition to the gaming state. When the display result of variable display is a big hit, the value of the special symbol process flag is updated to “6” which is a value corresponding to the pre-opening process for the big prize opening. Update the value to “0”.

  The pre-opening process for the special winning opening in step S136 is a process executed when the value of the special symbol process flag is “6”. In this process, the CPU 106 performs setting for starting control for opening the special variable winning ball apparatus 7 as a big winning opening. Then, the control for opening the special variable winning ball apparatus 7 is started, and the value of the special symbol process flag is updated to “7” which is a value corresponding to the large winning opening opening process.

  The special winning opening opening process in step S137 is a process executed when the value of the special symbol process flag is “7”. In this processing, the CPU 106 detects the winning of the game ball to the opened special variable winning ball device 7, sets the display control command for the winning ball payout command, the measurement of the opening time, and the round number of the opening cycle. I do. For example, the number of opening of the special variable winning ball apparatus 7 is counted for one big hit, and if the number of opening reaches 16 times, the condition for ending the specific gaming state (big hit gaming state) is finished. As a result, the value of the special symbol process flag is updated to “8” which is a value corresponding to the big hit end process. On the other hand, if the number of opening times has not reached 16, the special variable winning ball apparatus 7 is once closed and then opened again after a predetermined time has elapsed.

  The jackpot end process in step S138 is a process executed when the value of the special symbol process flag is “8”. In this process, the CPU 106 ends the jackpot gaming state by making settings for sending a predetermined jackpot end command to the display control board 12. Further, the CPU 106 clears the big hit state flag provided in the flag memory 172 and sets it to the off state. Then, the value of the special symbol process flag is updated to “0”.

  As described above, according to this embodiment, after the power is turned on to the pachinko gaming machine 1 and the game control main process is started, the CPU 106 permits the execution of the timer interrupt process to execute the loop process. Before the transition, since the random number circuit setting program 151 is executed to perform the random number circuit setting process, it is necessary to start / end the random number generation process within a limited interrupt processing time (for example, 2 milliseconds). Thus, an increase in processing load on the game control microprocessor 100 can be prevented.

  Preferably, the random number circuit setting process permits the execution of the timer interrupt process after the execution of the game state restoration process or the initialization process such as clearing the RAM 105 or initial setting for a predetermined work area. Therefore, it is desirable to execute this before moving to the loop processing.

  Further, since the CPU 106 determines whether or not the display result in the special game is a big hit using the random R generated by the random number circuit 103, the capacity of the program stored in the ROM 104 or the like can be reduced.

  Furthermore, since the value of the random R is updated by the random number circuit 103, the capacity of the program stored in the ROM 104 or the like can be reduced as compared with that updated by software.

  Moreover, since the value of the random R stored in the random value register 131 can be updated according to the setting made by executing the random number circuit setting program 151, by performing different settings for each pachinko gaming machine 1 The randomness of the random R read from the random value register 131 and used to determine whether or not the display result in the special game is a big hit can be improved.

  More specifically, the CPU 106 executes the random number maximum value setting module 151a included in the random value setting program 151, and sets the maximum value of the random R appropriately set for each pachinko gaming machine 1 by the user in the random number circuit 103. Thereafter, the random number circuit activation module 151d is executed to activate the random number circuit 103. In this way, by updating the value of the random R stored in the random value register 131 according to the maximum value of the random R set in the random number circuit 103, it is read from the random value register 131 and can be played in the special game. The randomness of the random R used for determining whether or not the display result is a big hit can be improved.

  Furthermore, by executing the count value permutation change program 154 to change the permutation that is the update order of the count values, the randomness of the count values input to the random value register 131 is increased. It is possible to improve the randomness of the random R that is issued and used to determine whether or not the display result in the special figure game is a big hit.

  Further, in response to the count value permutation change circuit 123 starting the count value update operation in accordance with the switched update rule, the CPU 106 counts the count value permutation change register 133 in which the count value permutation change data “01h” is written. Can be prevented from being continuously changed in the permutation of the count values output from the count value permutation changing circuit 123 and input to the random value register 131.

  Further, after the count value permutation change register 133 is initialized, the CPU 106 can further change the permutation of the changed count value by rewriting the count value permutation data “01h” in the count value permutation change register 133. it can.

  Further, by changing the initial value of the count value updated by the counter 121, it is possible to make it difficult to detect the cycle in which the count value is counted up from the initial value to the final value. Thereby, it is possible to prevent a fraudulent act such as outputting a predetermined signal aiming at a timing when the value of the random R read from the random value register 131 in step S143 coincides with the jackpot determination value and causing frequent jackpots. .

  Further, the CPU 106 changes the random number maximum value set in the random number circuit 103 by controlling the random number maximum value setting register 122 in which the random number maximum value setting data is written to be unwritable until the system is reset by the reset controller 102. Make it impossible. As a result, a malicious player can change the maximum random number and freely set the timing at which the random R value read from the random number register 131 matches the jackpot determination value, thereby preventing illegal acts such as frequent jackpots. can do.

  In addition, in order to change the initial value of the count value by the initial value changing method appropriately selected for each pachinko gaming machine 1 by the user, whether or not the display result in the special game is read out from the random value register 131 The randomness of the random R used for determining can be improved.

  Further, when random number maximum value setting data “0000h” to “0003h” for designating a value lower than the lower limit value “4” is written in the random number maximum value setting register 132, the CPU 106 stores the random number maximum value setting register 132 in this random number maximum value setting register 132. Since “0FFFh” is stored, a value of “4” or less can be prevented from being set in the random number circuit 103 as the maximum random number.

  When the initial value changed by the CPU 106 is larger than the random number maximum value, the comparator 122 sequentially outputs a count value update signal and continuously outputs the count value to the counter 121 from the changed initial value to the final value. The updated initial value can be further changed by the CPU 106 by outputting the notification signal. Thereby, it is possible to prevent the count value output to the random value register 131 from becoming larger than the maximum random number.

  Further, the CPU 106 sets the maximum value of the random number and the period of the internal clock signal in the random number circuit 103 and then activates the random number circuit 103. Therefore, after the power is turned on, the maximum value of the random number, the random number update method, and the internal clock signal It is possible to prevent a problem that random numbers are generated from the random number circuit 103 before setting the cycle.

  When the system is reset by the reset controller 102, the random number circuit activation data “80h” is written in the random number circuit activation register 140 so that the random number circuit 103 can be activated again.

  Furthermore, since the random number circuit 103 is built in the game control microprocessor 100, a space for the main board 11 can be secured, and counterfeiting such as installation of an illegal base can be made difficult.

  In addition, the update is performed by specifying in advance the timing at which the value of the random R stored in the random value register 131 is updated, that is, the timing at which the CPU 106 writes the count value update data “01h” into the count value update register 135. It is possible to prevent a random R value that has not been read from being read from the random value register 131.

  However, in this case, the count value update data “01h” is written in the count value update register 135 at an interval equal to or longer than the period of the system clock signal output by the clock circuit 101 from when the previous random R value was updated. There is a need. This is to ensure time for the CPU 106 to read the updated random R value from the random value register 131.

  In addition, this invention is not restricted to said embodiment, A various deformation | transformation and application are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, the counter 121 updates the count value by incrementing one by one from “1” to “4095”. However, the present invention is not limited to this, and the rule for updating the count value of the counter 121 is arbitrary. Further, the randomness of the count value input to the random value register 131 may be improved by switching the connection of each bit output terminal of the counter 121.

  In the above embodiment, the update range restriction means compares the count value input from the counter 121 with the random number maximum value specified by the random number maximum value setting data stored in the random number maximum value setting register 132. When the input count value is less than or equal to the random number maximum value, the input count value is output to the random value register 131. When the input count value is greater than the random number maximum value, the count value update signal is sent to the counter 121. The comparator 122 is an output.

  However, the present invention is not limited to this, and the update range restricting means performs a predetermined calculation according to the random number maximum value setting data stored in the random number maximum value setting register 132, and sets the update range of the count value. Anything to regulate is optional.

  For example, as shown in FIG. 29, the update range restricting means is designated by the random number maximum value setting data stored in the random number maximum value setting register 132 with the count values input from the counter 121 being “0” to “99”. In the case of the maximum random number “9”, the count value “0” when the input count value is “0” to “9”, the count value “1” when the input count value is “10” to “19”,. The count value update range may be restricted to “9” by outputting the count value “9” when the input count value is “90” to “99”.

  Furthermore, in the above embodiment, the random number read from the random number value register 131 is used as a big hit determination random number for determining whether or not the pachinko gaming machine 1 is put into a big hit gaming state by generating a big hit. . However, the present invention is not limited to this, and the read random number can be used for any purpose, and reach determination random numbers for determining whether or not to reach a loss, special symbols, and decorative symbols can be changed. Display random number for determining the variable display pattern used for display, display random number for determining the fixed symbol for the special symbol at the time of big hit, display for determining the fixed symbol for the special symbol at the time of loss Random numbers, random numbers for determining whether to change to a high probability state (special game state) in which the probability of generating a big hit is improved, or a display result in the normal figure game by the normal symbol display 40 is hit. It may be used for a random number for determining per normal drawing for determining whether or not to do so. However, it is not necessary to update all the random numbers listed here using the random number circuit 103, and some random numbers may be updated without using the random number circuit 103. For example, a part of these random numbers may be updated by executing a predetermined program during the game control interrupt process, or a random number update method using a refresh register may be used in combination. Good. Furthermore, the random number value read from the random number value register 131, the random number value updated by executing a predetermined program during the game control interrupt process, and / or the random number value updated using the refresh register, A value obtained by calculation such as addition, subtraction, integration, multiplication, and division may be used as a random number for determining jackpot, reach, variable pattern, and the like.

  In the above embodiment, the gaming machine incorporating the random number circuit 103 is variable after the first type pachinko gaming machine, that is, the variable display execution condition (for example, winning to the normal variable winning ball apparatus 6) is established. A variable display device (for example, variable) that variably displays a plurality of types of identification information that can be identified based on the establishment of a display start condition (for example, the previous variable display and end of jackpot gaming state in the variable display device 4). The display device 4) is a gaming machine that controls to a specific gaming state (for example, a big hit gaming state) that is advantageous to the player when the display result of variable display becomes a predetermined specific display result.

  However, the present invention is not limited to this. For example, a gaming machine having a built-in random number circuit 103 uses start detection means (for example, a start ball detector) that detects a game medium in a start area provided in the game area. A variable winning device having a variable winning device (for example, a variable winning ball device) that performs a starting operation (for example, a releasing operation) that changes from a second state unfavorable to the player to a first state advantageous to the player by detection. The variable winning device is set to the first state in a specific manner more advantageous to the player than the starting operation by detection of specific detection means (for example, a specific ball detector) that detects the game medium in a specific area provided in It may be a second type pachinko gaming machine that generates a specific gaming state to be controlled (for example, a big hit gaming state).

  In this case, the random number read from the random value register 131 is used for determination of the upper limit number of rounds in a specific gaming state (for example, a big hit gaming state) or for determination related to a change in the internal structure of a variable winning device (for example, a variable winning ball device). It can be used as a random number.

  Furthermore, the gaming machine incorporating the random number circuit 103 is provided on the condition that a game ball is detected by special detection means (for example, a specific ball detection switch or a special region switch) provided in a special area (for example, a special device operation area). During the period in which the right is generated and the right is generated, start detection means (for example, an operation ball detection switch or a start port switch) provided in a start area (for example, an operation winning port or a starting port in a starting winning device) Based on the detection of the game ball, control is performed to change the special variable prize-winning device (for example, a big prize opening) from a state unfavorable for the player (for example, a closed state) to a state advantageous for the player (for example, an open state). It may be a third type pachinko gaming machine that can be performed.

  This type 3 pachinko gaming machine has a variable display device that displays a display result related to opening and closing of a winning device that generates a right generation state by winning a prize (so-called normal symbol type type 3 pachinko gaming machine) In this case, the random number read from the random value register 131 can be used as a random number for prior determination of a normal symbol.

  In addition, when the 3rd type pachinko gaming machine displays a specific display result on the variable display device, the right generation state is generated for the game medium that causes the variable display device to derive the specific display result. In the case of a gaming machine (a so-called judgment symbol type type 3 gaming machine) that guides a game ball to the specific detection device to be used, the random number read from the random number value register 131 is used as a random number for prior judgment of the judgment symbol. Can do.

For example, interrupt prohibition is performed in step S1. Or may be performed immediately after setting the interrupt mode to mode 2 in step S2. Further, immediately after setting the stack pointer designation address to the stack pointer in step S3, immediately after setting the register such as CTC 107 in step S4, or immediately after setting for timer interruption in step S11. Good.

  In the above embodiment, in the game control interrupt process, the CPU 106 executes the random number value update process after the count value permutation change process in step S105 and before the special symbol process process in step S107. The present invention is not limited to this, and is arbitrary as long as the game control interrupt process is in progress. For example, the random number value update process may be executed before the display random number update process in step S103. The random value update process may be performed after the display random number update process in step S103 and before the initial value change process in step S104. Further, after the initial value change process in step S104, step S105 is performed. It may be performed before the count value permutation change processing by.

  Furthermore, in the above embodiment, when initial value change method setting data “03h” for designating the third initial value change method is stored in the area of address 1F97h in the user program execution data area, the CPU 106 The initial value of the count value updated by 121 is changed to the addition value of the value stored in each address of the RAM 105. However, the present invention is not limited to this, and when the initial value change method setting data “03h” is stored, the value to be changed is based on the value stored at a predetermined address in the RAM 105. If it is a thing, it is arbitrary. For example, the CPU 106 may change the initial value of the count value updated by the counter 121 to an integrated value or a multiplied value of a value stored in each address of the RAM 105.

  Further, the device configuration shown in FIGS. 1 and 2, the block configuration shown in FIGS. 3, 4 and 20, the register configuration shown in FIGS. 5, 8 and 10 to 13, and the program shown in FIGS. The configurations shown in FIGS. 6 and 21 and the flowchart configurations shown in FIGS. 22 to 28 can be arbitrarily changed and modified without departing from the spirit of the invention.
