IPC: A63F7/02
Filed: 2020-10-16
Abstract: To provide a game machine capable of suppressing a decrease in the rate of operation of a game machine by a standby performance while the standby performance including a game machine information suggestive performance for suggesting game machine information is executed in a non-game progress state.SOLUTION: Since execution of the entire part or one part of a game machine information suggestive performance for suggesting game machine information is disabled in a non-game progress state until an information suggestive condition is satisfied after power of a game machine is turned on, a player cannot know the entire part or one part of game machine information suggested by the game machine information suggestive performance. Accordingly, a determination material regarding whether a game is played or not in a game machine cannot be obtained properly in a non-game progress state. A player who requests game machine information is allowed to remember feelings for playing a game. Therefore, a decrease in the rate of operation of a game machine by a standby performance can be suppressed.SELECTED DRAWING: Figure 19
