Inventor: TERAMOTO SHUNSUKE
IPC: A63F5/04
Filed: 2014-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a game machine posing no problem for a progress management of a game, even when giving room for a player's intervention relating to execution of a performance.SOLUTION: When a bet button is depressed during execution of first freeze processing, the game machine drives reels to execute special rotation, however, in a first margin period in the first freeze processing, invalidates the depressing operation of the bet button. Namely, in the first margin period during execution of the first freeze period, the depressing operation of the bet button is not accepted. Even when the depressing operation of the bet button is executed immediately before reaching the first margin period, the first margin period is set longer than a period required for the special rotation operation, so that the special rotation operation is completed before the first freeze period is terminated, thus capable of stabilizing the first freeze period.
