Filed: 2020-12-14
Abstract: To provide a game machine capable of enhancing an interest in a game.SOLUTION: A privilege game advantageous to a player is executed by privilege game execution means on the basis of passage of a game ball through a specific area. Second identification information indicating a determination result of second determination means is dynamically displayed by second dynamic display means. A period in which the second identification information is dynamically displayed by the second dynamic display means is determined by second dynamic display period determination means. A pre-privilege game until a privilege game is executed is executed by pre-privilege game execution means, after the determination result of the second determination means becomes a second determination result. The second dynamic display period determination means determines so that the total of the length of the dynamic display period when the determination result of the second determination means is the second determination result and the length of a period of the pre-privilege game is equal to the length of the dynamic display period when the determination result of the second determination means is a prescribed determination result other than the second determination result. Therefore, the game machine has an effect which can enhance an interest in a game.SELECTED DRAWING: Figure 1
