To provide a game machine capable of improving interest of a game effectively by using step-up notice performance.

A CPU 101 for performance control executes first step-up notice performance and second step-up notice performance for informing stepwise that success may be obtained by changing once or a plurality of times notice performance at a timing determined beforehand following the order determined beforehand during one-time variable display, and can execute the first step-up notice performance and second step-up notice performance simultaneously in the same period during the variable display. Further, the CPU 101 changes notice performance in the first step-up notice performance at a prescribed change timing, and changes notice performance in the second step-up notice performance at a timing different from the change timing for the first step-up notice performance.
