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 machine includes a game control means, a shooting means, and a regular symbol control means. The game control means (110) acquires a counter value that first and second random number generation means (111D) update, and uses the acquired counter value as a random number for a game control. The shooting means includes: an oscillation means for generating an oscillation signal of a predetermined oscillation frequency; a shooting control means for controlling the shooting on the basis of the oscillation signal and a signal from a shooting adjustment means; a drive source 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 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. |
