PROBLEM TO BE SOLVED: To provide a game machine which can improve properties of security against unjust acquisition of a benefit. SOLUTION: When a start signal is outputted on the basis of winning of a prize for pachinko balls, a main control device acquires a big-hit counter value and determines a big-hit on the basis of this value. The big-hit counter is added to an upper-limit value, starting from a prescribed value, only at one time immediately after return to a reset, and this brings about the possibility that a state of return to the reset is made up on the basis of unjust output of a reset signal from an unjust board to a reset terminal of the main control device and that the big-hit is acquired unjustly on the basis of unjust output of the start signal at the timing of the big-hit. Since a reset switch is mounted on a main board common to the main control device, however, a connector for the reset switch is dispensed with and therefore the unjust board can not be connected to the reset terminal of the main control device through the connector for the reset switch. Accordingly, unjust acquisition of the big-hit is prevented.
