<p>PURPOSE:To vary a variable prize-winning device in a profitable state for a player by generating a prize mode when a result of operation in the third arithmetic and storing means amounts to the number of pinballs set by a difference number-setting device. CONSTITUTION:After a shot pinball falls into a prize-winning pocket, it is detected by a safe pinball sensor 52 provided on a safe pinball-dropping route 51, and then the number of prize pinballs set by a setting switch 65 for them is added on a prize pinball memory of the second arithmetic and storing means. When the value on a memory of a prize pinball signal exceeds the number of 10, it is deducted by the number of 10 after the prize pinball signal is outputted. Whenever a safe pinball or an out pinball is detected by a retrieved pinball sensor 55 provided on a retrieved pinball-dropping route 54, the number of 1 is added on a retrieved pinball memory of the first arithmetic unit and resister in a CPU 57. When the value on a memory of a retrieved pinball signal exceeds the number of 10, it is deducted by the number of 10 after the retrieved pinball signal is outputted. A difference of the number between retrieved and prize pinballs is operated and stored by a difference-operating resister of the third arithmetic and storing means in the CPU 57. When the above difference is equal to a difference of the number between retrieved and discharged pinballs, a special game is started.</p> |
