Title: Game machine
Inventor: KITO TOSHIHIKO
IPC: A63F7/02
Filed: 2019-09-05
Abstract: To show novel amusement.SOLUTION: When separation between a current index (NowIndex) and the maximum variation value (MaxIndex) becomes a certain value or larger during execution of a button successive hitting performance, a current index is updated (+1) until the separation width becomes a designated range or less regardless of a lottery result. The current index is also forced to be progressed to the maximum fixed value by operating a lever member. Accordingly, when a lottery for progressing the current index is not won continuously, the progress of a scenario is not hindered as long as proper depression of a push button is performed. Just before effective time of the push button expires, depressing the push button once can prevent a performance that is nearly identical to a final result from being seen. Further, a player who does not wish to successively hit or long-press the push button can confirm the final result as fast as possible by operating the lever member.SELECTED DRAWING: Figure 68
