Filed: 2020-02-29
Abstract: To suppress a decline of interest of a game machine having a specific area.SOLUTION: In a V round of a scheduled V passage big winning, when the number of balls having entered a V attacker reaches "2" (second predetermined value C2), a movable piece 150 in a non-operating state is first-activated and becomes in an operating state, and thereafter, when the number of balls having entered the V attacker reaches "9" (third predetermined value C3), the movable piece 150 in an operating state is second-activated and becomes in a non-operating state. When the game balls having entered the V attacker in the V round are distributed to a specific area 39 to cause a V passage to be performed, as long as the game balls enter the V attacker without delay, distribution to the specific area 39 (V passage) almost certainly occurs. As a result, a situation that is disadvantageous to the player, such as losing the opportunity of the V passage in the V round of the big winning game related to the scheduled V passage big winning, is unlikely to occur, and it is possible to suppress a decline of interest due to the occurrence of such a situation.SELECTED DRAWING: Figure 33
