Inventor: ICHIHARA TAKAAKI
IPC: A63F7/02
Filed: 2020-05-21
Abstract: To provide a game machine capable of suppressing a decline in game amusement although a presentation over a prescribed period is performed.SOLUTION: Although a presentation can be performed till the end without being terminated in the middle before the start of a big win game state due to a part of presentation of a battle presentation short being performed during a performance period of the big win game state, compared to performing all presentations of the battle presentation short as a variable display presentation during a variable display of a second special symbol, a variation time can be shortened. Therefore, a period from the start of a variable display of the special symbol till the big win game state is finished can be shortened. Also, even if the time required for the variable display is reduced, a battle presentation can be performed over a long period from the start of the variable display till the big win game state is being performed. Therefore, the variation time can be reduced by performing the battle presentation without simplifying a presentation content to suppress a decline in game amusement due to a simplification of the presentation content.SELECTED DRAWING: Figure 176
