PROBLEM TO BE SOLVED: To provide a game machine which makes it possible to accurately grasp the number of game balls not put out by securely executing detecting of put-out game balls in the case that the power supply stops, and also to improve convenience of the game machine operation. SOLUTION: A CPU executes a recovery processing to recover a control state based on storage contents stored in a backup RAM, if all of a plurality of recover conditions are satisfied, which are for determining whether or not to recover to the control state before power supply stops. The CPU executes a initialization processing for initializing storage contents of a variable data storing means if at least one condition of a plurality of recover conditions is not satisfied. If a signal is output from a clear switch, initialization processing is executed regardless of a plurality of recover conditions. The CPU also executes processing at a time of power supply stopping for storing data necessary for recovering the control state when the power supply stops, and in this processing, the CPU also monitors detection signals from a prize ball count switch.
