The main control board 41 and the sub control board 42 are provided with connection terminals, respectively, and the main control board 41 and the sub control board 42 are electrically connected by connecting the connection terminals with a connection cable or the like. The sub control board 42 is housed in a housing case (not shown) in the same manner as the main control board 41, and protects the sub control board 42 from being touched by anyone.

  The main control board 41 includes a main CPU (central processing unit) 41a, a main ROM (read only memory) 41b, a main RAM (random access memory) 41c, and a big hit lottery unit 41d. The main CPU 41a reads a game control program stored in the main ROM 41b in response to an input signal input from the winning ball detection sensor 16, generates a command for controlling the gaming state of the pachinko machine, and also generates a sub-control board 42. The command information is transmitted to and executed in a predetermined gaming state. In the main ROM 41b, a game control program, a random number generation processing program, a random number table, and the like are stored in predetermined areas, and these are read out by the main CPU 41a and used appropriately so as to be processed. The main RAM 41c is a working area and is used for temporary storage or rewriting of data used in the game.

  When the signal from the winning ball detection sensor 16 is input, the main CPU 41a drives the ball payout device 45 based on the game control program stored in the main ROM 41b to supply a predetermined number of winning balls on the supply tray 6 Pay out. Note that the number of prize balls may be set as appropriate according to the type of each prize-winning slot 10 or 11 containing game balls. The ball launcher 17 is connected to the main CPU 41a, and the driving is controlled by the main CPU 41a.

  The sub control board 42 includes a sub CPU 42a, a sub ROM 42b, and a sub RAM 42c. The sub CPU 42a appropriately reads out the control program for the sub control device stored in the sub ROM 42b, and according to the control signal input as command information from the main control board 41, the symbol variable display device 9 and Drive control of the speaker 21 and the like is performed. The sub-RAM 42c is a working area, and is used for temporary storage or rewriting of data used in the control of the symbol variable display device 9 and the speaker 21.

  When the pachinko ball 7 entering the start winning opening 10 is detected by the winning ball detection sensor 16, a start signal is input to the main CPU 41a. The main CPU 41a operates the big hit lottery section 41d in response to the start signal.

  The jackpot lottery unit 41d includes a random number generator, a random number sampling circuit, and a jackpot determination table. When the winning ball detecting sensor 16 of the start winning port 10 detects the winning of the pachinko ball 7, one random number value is lottery. To do. The lottery random value is checked against the jackpot table, whether or not to shift to the jackpot mode is determined as a result of the lottery determination, and information (for example, command) related to the determination is generated.

  In the jackpot determination table, random numbers are grouped into three groups according to their sizes. The three random number groups are assigned “normal jackpot” that shifts to the loss, normal jackpot mode, and “probability jackpot” that shifts to the probability fluctuation jackpot (hereinafter, probability variation jackpot) mode, which has a different probability of jackpot than normal. The winning determination is performed to determine whether to be lost or jackpot depending on which group the sampled random number value belongs to. When the lottery is completed, a lottery result signal is fed back to the main CPU 41a. The main CPU 41a sends a lottery result signal to the sub CPU 42a.

  When the “normal big hit” or “probable big hit” is drawn by the big hit lottery section 41d, the main CPU 41a rotates the attacker 13 to the open position, and the attacker 13 is opened for 30 seconds or the big prize opening 18 A predetermined round (for example, 15 rounds) is continuously executed, assuming that 10 pachinko balls 7 are won (or 10 pachinko balls 7 are detected by the big winning ball detection sensor 19). Further, when “probable big hit” is drawn, until the next big hit is drawn, or until a winning determination is made in the big hit lottery section 41d for a predetermined number of times (for example, 7 times), a probable big hit determination table different from the normal time is generated. Used at the time of lottery.

  In the sub ROM 42b of the sub control board 42, graphic data of each special symbol, a stop symbol random number sampling circuit, and a stop symbol table are stored. When the lottery result signal is input, the sub CPU 42a samples the random number value based on the stop symbol random number sampling circuit stored in the sub ROM 42b, and compares the sampled random number value with the stop symbol table. There are three types of stop symbol tables for lost, big hit, and probable big hit, and the random number sampled is collated with the stop symbol table corresponding to the lottery result in the big hit lottery section 41d. Each stop symbol table is assigned a special symbol combination for stopping on the winning active line to the grouped random value, and the group to which the sampled random value belongs The combination of special symbols to be stopped on the winning line is determined. The sub CPU 42a controls the change display and stop display of the special symbol on the symbol variable display device 9 based on the determined combination of the special symbols. In the stop symbol table, for example, when two special symbols are stopped on the winning line, a special symbol is aligned, that is, a special symbol change mode when reaching a reach state, a symbol variable display It also includes data on whether or not to make a special symbol change mode different from the normal time, such as a special symbol change mode in a reach notice and a special symbol stop mode in a jackpot notice.
