Filed: 2021-08-24
Abstract: To provide a game machine capable of enhancing interest in a game.SOLUTION: A main-side MPU 92 executes winning/losing determination processing to hold information at a special pattern side, and starts a game round. When the game round, where a result of the winning/losing determination corresponds to a winning result, is completed, an entry effective period of a distribution through winning part occurs, and entry to the distribution through winning part occurs and hence a distribution execution mode occurs. A distribution winning device is opened in a distribution execution mode, and an opening/closing execution mode occurs when V winning is generated by game balls entering the distribution winning device. In this case, distribution determination processing is executed when entry to the distribution through winning part occurs. However, the distribution execution mode occurs regardless of a result of the distribution determination processing. A first distribution execution mode and a second distribution execution mode exist as a distribution execution mode, a degree of expectation toward occurrence of V winning in the first distribution execution mode is higher than that in the second distribution execution mode.SELECTED DRAWING: Figure 6
