IPC: A63F7/02
Filed: 2019-06-30
Abstract: To increase game interest by executing a performance to make a player pay attention to a stop display of identification information.SOLUTION: In a performance of chance combinations in a state A (low probability low base state), stop symbols are determined as chance combinations when three symbols composing a performance symbol are stopped and displayed in a combination in which they are not the same number but all of them are the same color, and a big winning reliability is suggested with the color of the stopped and displayed chance combinations. On the other hand, in a performance of chance combinations in a state B (low-probability high-base state or high-probability high-base state), stop symbols are determined as chance combinations when three symbols composing a performance symbol 8 are stopped and displayed in a symbol combination in which they are not the same number and in a specific order (e.g., ascending from left to right), and the big winning reliability is suggested depending on the type of a medium symbol among the three symbols composing the chance combination. Thereby, it is possible to increase game emotion by allowing a player to focus on the chance combinations according to the game state.SELECTED DRAWING: Figure 59
