PROBLEM TO BE SOLVED: To provide a game machine capable of being securely restored when the power supply is restarted to the control state when the power supply is stopped. SOLUTION: A game control means sets a backup flag in RAM in a power supply stopped time process and generates the checksum by the arithmetic operation based on the data in the RAM, and the checksum is stored in the RAM. When the power supply is restarted, the game control means determines whether the backup flag is stored in the RAM or not. If it is determined that the backup flag is stored in the RAM, the game control means determines whether the content of storage in the RAM is normal or not based on the checksum and executes a state restoration process for restoring the control state based on the content of storage saved in the RAM on condition that it is determined that the content of storage in the RAM is normal. If it is determined that the backup flag is not stored in the RAM, the game control means initializes the content of storage in the RAM area without executing the determination based on the checksum.
