PROBLEM TO BE SOLVED: To provide a game machine having random number generation means for generating a random number to be used for a game control, so that a sharp-shooting of a predetermined random number may be prevented to retain the fairness of a game.SOLUTION: The game machine comprises: game control means (110) for controlling the advancement of a game; first and second random number generation means (111D) for circulating to update a counter value by setting a predetermined number within an update range; and launching means (72) for launching a game ball into first and second startup and winning areas, in which first and second variable display games are started, and into a game area. The game control means acquires the counter value to be updated by the random number generation means, at an arbitrary timing, and utilizes the acquired counter value as a random number for a game control. The launching means performs a unit operation, when a drive signal of a predetermined pulse number is applied, performs an injection of the game balls, and decides the injection cycle in a manner to correspond that pulse number. The update cycle and the update range of the random numbers in the first and second random number generation means are individually set such that the synchronous intervals between the injection cycle and the update cycle are made longer than the maximum variation time periods of the first and second variable display games. |
