PURPOSE:To give a feeling of expectation that many prize balls can be acquired at the time of a special game and increase an interest by variably displaying patterns based on the occurrence of the special game, and changing the prize occurrence probability to a high probability when the stop pattern is a special mode until the prescribed release conditions are met. CONSTITUTION:A start port 30 opened once and a start port 31 opened twice are arranged at both bases of a variable prize device 27 provided nearly at the center of the game board of a Japanese pinball game (pachinko) machine. A normal pattern indicator 41 variably displaying patterns when a ball passes through a specific game 28 is provided, and the start port 31 is opened for a short time when its prize is displayed. The variable prize device 27 is provided with a special prize port 50 at the center and general prize ports 51 on the right and the left in a prize space, and it is also provided with switching vanes 55 opened when balls enter the start ports 30, 31. Patterns of a variable indicator 60 are variably displayed based on the occurrence of a special game when the switching vanes 55 are opened, and the prize occurrence probability of the normal pattern indicator 41 is changed to a high probability when the stop pattern is a special mode. |
