PROBLEM TO BE SOLVED: To make a Pachinko (Japanese pin ball game) machine, in which a big prize winning port is continuously opened by the occurrence of a big hit, simple in configuration and low in manufacturing cost. SOLUTION: A hit ball enters into a start prize winning port which is arranged on a game board so that the patterns of a pattern fluctuation display equipment 7 are stopped after fluctuation display. When the stop patterns becomes specified patterns with a possibility, a state becomes the special game one so as to permit the big prize winning port to become the open state. When a prescribed number of big balls enter the big prize winning port or a prescribed restricting time elapses, the big prize winning port becomes a closed state. When a prescribed continuity condition is established during the open state, the big prize wining port is closed once but is soon opened again so that the big prize winning port is continuously opened with prescribed times as a limit at the time of the establishment of the continuity condition after that. In this case, the continuity condition is the one where the entering number of the hit balls into the big prize winning port reaches a prescribed number. |
