IPC: A63F7/02
Filed: 2020-03-19
Abstract: To provide a game machine capable of normally performing main control of a game while achieving various kinds of control by determining contents relating to a lottery or the like.SOLUTION: In a Pachinko machine 10, apart from a jackpot lottery performed at the start of executing a variation performance, each counter value acquired and reserved upon trigger winning is read ahead, and read-ahead processing for determining a result of the jackpot lottery is executed. While the read-ahead processing is executed in main processing, the jackpot lottery or the like is executed in timer interruption processing to be executed more preferentially than the main processing. Thus, since the timer interruption processing is executed preferentially even during the execution of the read-ahead processing in the main processing, the jackpot lottery can be performed without any delay at the start time of the execution of the variation performance. On the other hand, even if the timer interruption processing is executed during the read-ahead processing, it is successively performed after completion of the timer interruption processing and thus the read-ahead processing can be completed reliably.SELECTED DRAWING: Figure 24
