PROBLEM TO BE SOLVED: To secure fairness of a game by preventing sharpshooting of a prescribed random number value in a game machine having a random number generation means for generating a random number for use in a game control.SOLUTION: A game control means (110) acquires a counter value that a random number generation means (111D) updates, at an optional timing, and uses the acquired counter value as a random number for a game control. A shooting means includes: an oscillation means (212) for generating an oscillation signal of a predetermined oscillation frequency; a shooting control means (210) for controlling the shooting on the basis of the oscillation signal and a signal from a shooting adjustment means; a drive source (721) having a predetermined number of driving pulses and driving a ball shooting mallet for shooting a game ball by the shooting control means; and a clock division circuit (222) for adjusting the oscillation frequency by a predetermined division ratio. A game machine is so set that a synchronization interval of the shooting frequency determined based on the oscillation frequency, the division ratio, and the number of driving pulses and a random number updating frequency by the second random number generation means becomes longer than a maximum variation time of the second variable display game. |
