PROBLEM TO BE SOLVED: To provide a game machine using a value of a counter for counting the number of clock signals as a random number used for the determination of a jackpot or the like, in which a counter circuit is stopped to make it hard to commit a fraudulent act of continuously generating jackpots. SOLUTION: The game machine executes an auxiliary game according to the passage of a game ball into a starting area, and when the auxiliary game has a special result, a privilege is granted to a player. The game machine is provided with a counter unit for performing counting operation based on a clock signal with a predetermined cycle, a counter value-holding unit for importing and holding a value counted by the counter unit based on the detection result of a start prize winning detection unit, a counter value-acquiring unit for acquiring a value held by the counter value-holding unit based on the detection result of the start prize winning detection unit, and a counter value-determining unit for determining whether an acquired counter value agrees with a counter value having been stored in a start prize winning storage unit or not every time a new counter value is acquired, wherein a predetermined number of times of continuous agreement between counter values leads to notification of an abnormal condition.
