Title: Game machine
IPC: A63F7/02
Filed: 2021-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of providing a player with a suggestive presentation having a high ingenuity. 
     SOLUTION: If a performance of a continuous notice presentation is determined, a value obtained by adding one (1) to the number of variation presentation for causing the continuous notice presentation is set in a continuous notice performance counter 223e. And, every time a variation pattern command that is a start instruction of the variation presentation is received, the continuous notice performance counter 223e is referred to, then if the referred value is greater than one (1), the continuous notice presentation is performed to the variation presentation and the value of the continuous notice performance counter 223e is subtracted by one (1). If the value is one (1), the continuous notice presentation is always caused not to be performed, and the value of the continuous notice performance counter 223e is subtracted by one (1). In this way, after the continuous notice presentation is finished, it is possible to suppress a continuous performance of the continuous notice presentation. Therefore, a decline of expectation a player has toward the continuous notice presentation, which is generated by continuous performances of the continuous notice presentation or a single notice presentation, can be suppressed.
