Description

  The present invention relates to a gaming machine represented by a pachinko gaming machine and the like, and more particularly to a gaming machine that can prevent an illegal act by a “hanging board” or the like.

  This type of pachinko gaming machine is equipped with a display device capable of variably displaying a plurality of types of symbols, and is configured to start variably displaying when a hit ball that has been driven into the game area passes through the symbol operating gate. ing. When this variable display stops in accordance with a predetermined combination of symbols, a big hit is made, a predetermined game value is given to the player, and a large amount of game balls can be paid out.

  Whether or not the jackpot is generated is determined at the timing when the hit ball passes the symbol operating gate. In other words, a counter that is periodically updated by 1 count in a certain range (for example, by 1 count every 2 ms, in the range of 0 to 200), and when the hit ball passes the symbol operation gate, the counter is updated. When the read counter value matches a predetermined value such as “7”, a jackpot is generated.

  Recently, however, there have been reports of fraudulent acts using illegal boards called “hanging boards”. This fraudulent act is that an illegal board is hung between the control board and the display board of the display device (attached with an illegal “hanging board”) to unreasonably generate a big hit. Specifically, a counter (counter that is periodically updated within a certain range) in the “hanging board” is operated in the same manner as the counter for determining the jackpot provided in the pachinko gaming machine. The counter is reset (cleared to 0) when the pachinko gaming machine is turned on, and the occurrence timing of the jackpot in the “hanging board” is grasped. And, in accordance with the grasping timing of the jackpot, illegally generate the symbol operation gate passing signal of the hit ball in the “hanging board”, and output it to the control board of the pachinko machine to generate an unreasonable jackpot It is to let you. In game halls and the like, there has been a problem that a large amount of damage has been caused by fraudulent acts using this "hanging board".

  The present invention was made to solve the above-described problems, and provides a gaming machine that makes it impossible to grasp the timing of occurrence of a jackpot and can prevent fraud using a “hanging board” or the like. The purpose is to do.

In order to achieve this object, the gaming machine according to claim 1 reads a value of the random number counter, a random number counter updating means for updating the value of the random number counter within a predetermined range, and a value of the random number counter by a predetermined trigger. And a control means for giving a predetermined game value to the player when the value of the random number counter read by the reading means matches a predetermined value. Is rounded by being updated a predetermined number of times by the random number counter updating means, and the random number counter updating means takes any value within the predetermined range when the value of the random number counter makes a round. are those as an initial value of the update performs the following peripheral updating, further said control means, for each value of the random number counter n circumference (either n is a natural number), the random number counter An initial value changing means for changing an initial value of updating of the updating means; an initial value counter which is updated in the same range as the predetermined range and used by the initial value changing means for changing the initial value; and for the initial value An initial value counter updating means for updating the counter value, and performs periodic processing based on a periodic interrupt signal, and after the end of the periodic processing, until the next periodic processing is performed A predetermined process is repeatedly performed, and the random number counter is updated by the random number counter updating unit in the periodic process, and the counter is updated by the initial value counter updating unit in the predetermined process. .
The gaming machine according to claim 2, in the gaming machine according to claim 1, the initial value counter value is updated a predetermined number of times by the initial value counter updating means, and the initial value counter The value counter updating means updates the next round by using any value within the predetermined range as an initial value when the initial value counter makes one round.
In the gaming machine according to claim 3, in the gaming machine according to claim 1 or 2, the random number counter is updated by the random number counter updating means only once in the regular processing.
The gaming machine according to claim 4 is the gaming machine according to any one of claims 1 to 3, wherein the initial value changing means updates the random number counter updating means every time the value of the random number counter makes a round. The initial value is changed.

According to the gaming machine of the present invention, the initial value for updating the random number counter for determining the jackpot is not a fixed value but a value changed by the initial value changing means. That is, every time the value of the random number counter makes n rounds, the initial value of the update of the random number counter updating means is changed based on the value of the initial value counter (n is any natural number) .
Updating of the random number counter is carried out at periodic processing that is performed on a regular interrupt signal, whereas, after the end of periodic processing of that is repeatedly executed during the period until the next periodic processing is performed In the predetermined processing, the initial value counter is updated . Therefore, the value of the initial value counter cannot be grasped with the “hanging board” or the like. In this way, the initial value of the update of the random number counter is determined by the value of the counter for the initial value, in which the count value cannot be grasped in the “hanging board” or the like. An illegal counter value cannot be matched with a random number counter value, and the occurrence timing of a jackpot cannot be grasped. Therefore, there is an effect that it is possible to prevent an illegal act of unreasonably generating a big hit using a “hanging board” or the like.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the present embodiment, description will be made using a pachinko gaming machine as an example of a ball game machine, in particular, a first type pachinko gaming machine. Of course, it is possible to use the present invention for the third type pachinko gaming machine and other ball game machines.

  FIG. 1 is a front view of the game board of the pachinko gaming machine P. Around the game board 1, there are provided a plurality of winning holes 2 through which 5 to 15 game balls are paid out by winning a hit ball. In the center of the game board 1, a liquid crystal (LCD) display 3 for displaying symbols as a plurality of types of identification information is provided. The display screen of the LCD display 3 is divided into three in the horizontal direction, and in each of the three divided display areas, symbols are displayed in a variable manner.

  Below the LCD display 3, a symbol operating gate (first type starting port) 4 is provided. When the hit ball passes through the symbol operating gate 4, the above-described variable display of the LCD display 3 is started. Below the symbol operation gate 4, a specific winning opening (large winning opening) 5 is provided. The specific winning opening 5 is a big hit when the display result after the fluctuation of the LCD display 3 coincides with one of the predetermined symbol combinations, so that the hitting ball is easy to win for a predetermined time (for example, 30 It is a winning opening that is opened (until the second elapses or 10 hitting balls are won). A V zone 5a is provided in the specific winning opening 5, and when the hit ball passes through the V zone 5a while the specific winning opening 5 is opened, a continuation right is established and the specific winning opening 5 is closed. Thereafter, the specific winning opening 5 is opened again for a predetermined time (or until a predetermined number of hit balls win the specific winning opening 5). The opening / closing operation of the specific winning opening 5 can be repeated up to 16 times (16 rounds), and the state in which the opening / closing operation can be performed is a state in which a predetermined game value is given (special game state). is there.

  FIG. 2 is a block diagram showing an electrical configuration of the pachinko gaming machine P. As shown in FIG. The control unit C of the pachinko gaming machine P includes a CPU 11 that is an arithmetic device, a ROM 12 that stores various control programs executed by the CPU 11, and a RAM 13 that is a memory for temporarily storing various data. And. The programs of the flowcharts shown in FIGS. 3 and 4 are stored in the ROM 12 as a part of the control program.

  The RAM 13 includes a random number counter 13a, an initial value counter 13b, and an initial value memory 13c. The random number counter 13a is a counter for determining the occurrence of a jackpot, and is updated by one count every 2 ms in the range of “0 to 200” by the random number counter update process (S10) of FIG. When the value of the random number counter 13a is “7”, for example, if the hit ball passes the symbol operating gate 4, a big hit is generated. When the jackpot occurs, a jackpot command is sent from the control unit C to the display device D described later. The display device D controls the variable display on the LCD display 3 to the jackpot state based on the jackpot command.

  The initial value counter 13b is a counter for determining the initial value of the update of the random number counter 13a. During the remaining time in the reset interrupt process of FIG. 3 (after the completion of each process of S3, the next reset interrupt process occurs) Until the same time, the random number counter 13a is repeatedly updated one count at a time in the range of “0 to 200”. The reset interrupt process is executed every 2 ms, but the processing time of each process executed in one reset interrupt process varies depending on the game situation. Therefore, the remaining time of the reset interrupt process is not a fixed time but an indefinite time that varies depending on the game situation. Since the “hanging board” cannot grasp the value of the initial value counter 13b that is repeatedly updated during this indefinite time, the value of the initial value counter 13b is used as the initial value for updating the random number counter 13a. Measures for "hanging boards" are taken.

  The initial value memory 13c is a memory for storing an initial value for updating the random number counter 13a. In this embodiment, the initial value of the update of the random number counter 13a is changed every time the random number counter is updated once. Therefore, when the updated value of the random number counter 13a matches the value of the initial value memory 13c, one round of updating of the random number counter 13a is completed, so that when the two values 13a and 13c match, The initial value counter 13b is written into the random number counter 13a and the initial value memory 13c, and the initial value of the update of the random number counter 13a is changed. Thereby, even if the initial value of the update of the random number counter 13a is changed, the uniformity of the random number (the same value is not taken when continuously acquired, and all values can be extracted with the same probability). A random value can be obtained.

  The CPU 11, ROM 12, and RAM 13 are connected to each other via a bus line 17. The bus line 17 is also connected to an input / output port 15, which is connected to the display device D and other input / output devices 16. The control unit C sends operation commands to the display device D and other input / output devices 16 via the input / output port 15 and controls these devices. The fluctuation display on the LCD display 3 and the opening / closing operation of the specific winning opening 5 are also controlled based on this operation command.

  The display device D includes a CPU 21, a program ROM 22, a work RAM 23, a video RAM 24, a character ROM 25, an image controller 26, an input / output port 27, and the LCD display 3. The CPU 21 of the display device D performs display control (variable display) of the LCD display 3 in accordance with an operation command output from the control unit C. The program executed by the CPU 21 is stored in the program ROM 22. Has been. The work RAM 23 is a memory that stores work data used when the CPU 21 executes a program.

  The video RAM 24 is a memory for storing data to be displayed on the LCD display 3, and the display content of the LCD display 3 is changed by rewriting the content of the video RAM 24. That is, the variable display of the symbols in each display area is performed by rewriting the contents of the video RAM 24. The character ROM 25 is a memory for storing character data such as symbols displayed on the LCD display 3. The image controller 26 adjusts the timings of the CPU 21, the video RAM 24, and the input / output port 27, intervenes in reading and writing data, and displays display data stored in the video RAM 24 at a predetermined timing with reference to the character ROM 25. It is displayed on the LCD display 3.

  Next, each process executed by the pachinko gaming machine P configured as described above will be described with reference to the flowcharts of FIGS. 3 and 4. FIG. 4 is a flowchart of reset interrupt processing executed every 2 ms in the control unit C of the pachinko gaming machine P. In the reset interrupt process, first, it is checked whether or not the process is the first process executed after power-on (S1), and if it is the first process executed (S1: Yes), the RAM 13 Initialization is performed (S2).

  After initialization of the RAM 13 (S2) or when it is determined that the reset interrupt process is executed after the power-on in the process of S1 (S1: No), the random number counter update of FIG. Processing is executed (S10).

  FIG. 4 is a flowchart of the random number counter update process. By this process, the value of the random number counter 13a is updated by one count in the range of “0 to 200”. In the random number counter update process, first, it is checked whether or not the value of the random number counter 13a is “200” or more (S11). If the value of the random number counter 13a is less than “200” (S11: No), the value of the random number counter 13a is updated by adding “1” (S12). On the other hand, if the value of the random number counter 13a is “200” or more (S11: Yes), the value is cleared to “0” (S13). By each processing of S11 to S13, the value of the random number counter 13a is updated by 1 count every 2 ms in the range of “0 to 200”.

  After updating the value of the random number counter 13a, it is determined whether or not the value of the random number counter 13a matches the value of the initial value memory 13c (S14). If the values 13a and 13c do not match (S14: No), the value of the random number counter 13a has not yet been updated once. In this case, the initial value of the update of the random number counter 13a is changed. The random number counter update process is terminated without returning to the reset interrupt process.

  On the other hand, if the value of the random number counter 13a matches the value of the initial value memory 13c (S14: Yes), it means that the update of the random number counter 13a has been completed once. Therefore, in this case, in order to change the initial value of update of the random number counter 13a, the value of the initial value counter 13b at that time is read (S15), and the value of the read initial value counter 13b is changed to the random number counter 13a. The initial value memory 13c is written to change the initial value of the update of the random number counter 13a and store the initial value of the update (S16, S17). After changing the initial value of the update of the random number counter 13a and the value of the initial value memory 13c (S16, S17), the random number counter update process is terminated and the process returns to the reset interrupt process.

  When the execution of each process (S3) is completed after returning to the reset interrupt process, the value of the initial value counter 13b is maintained until the next reset interrupt process occurs (during the remaining time of the reset interrupt process). Are updated repeatedly (S4 to S6). First, it is checked whether or not the value of the initial value counter 13b is “200” or more (S4). If it is less than “200” (S4: No), the value of the initial value counter 13b is incremented by “1”. (S5). On the other hand, if the value of the initial value counter 13b is “200” or more (S4: Yes), the value is cleared to “0” (S6). This updating of the value of the initial value counter 13b is repeated until the next reset interrupt process occurs.

  As described above, the remaining time of the reset interrupt process is indefinite. Therefore, the value of the initial value counter 13b repeatedly updated during such an indefinite time cannot be grasped by the “hanging board”. In the pachinko gaming machine P of the present embodiment, since the initial value of the update of the random number counter 13a that determines the occurrence of the jackpot is changed based on the value of the initial value counter 13b, it is illegally attached to the pachinko gaming machine P. Even if the “hanging board” is reset in accordance with the power-on of the pachinko gaming machine P, the value of the internal counter cannot be matched with the value of the random number counter 13a. Therefore, the “hanging board” cannot grasp the occurrence timing of the jackpot, and cannot output the passing signal of the symbol operation gate 4 to the control unit C of the pachinko gaming machine P in accordance with the occurrence timing of the jackpot. Therefore, it is possible to prevent an illegal act of unjustly generating a big hit using the “hanging board”.

  In addition, as a predetermined opportunity of Claim 1, the generation | occurrence | production trigger of the design action gate passage signal of a hit ball corresponds. Further, the reading means corresponds to a reading process (not shown) of the value of the random number counter 13a executed when the hit ball passes the symbol operating gate 4.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, in this embodiment, the initial value for updating the random number counter 13a is changed every time the random number counter 13a is updated once. However, the change of the initial value of the update of the random number counter 13a is not necessarily limited to this, and may be changed every time the update of the random number counter 13a is performed n times (n is a natural number).

  The modification of this invention is shown below. 2. The ball game machine according to claim 1, further comprising an interrupt process that is executed periodically, and wherein the changing means includes an initial value counter for determining an initial value for updating the random number counter, and an initial value counter for the initial value counter. A second update means for updating a value, and the second update means is repeatedly executed during the remaining time of the interrupt process. Since the remaining time of the interruption process changes according to the control state of the gaming machine, it cannot be grasped by the “hanging board” or the like. During the remaining time, the second updating means is repeatedly executed to repeatedly update the initial value counter value for determining the initial value of the random number counter update. It is possible to make it impossible to grasp.

  In the ball game machine 1, the changing means includes an initial value memory for storing an initial value of the update of the random number counter, and when the value of the initial value memory matches the value of the random number counter, A bullet ball game machine according to claim 2, wherein an initial value for updating the random number counter is changed based on a value of the value counter.
