Abstract

PURPOSE: To make it possible to determine if conditions of continued winning are met by arranging that, when a variable winning device is in the open state and game balls have passed through a specific winning zone within a specific period of time, the open state is resumed after finishing the opening operation of the variable winning device, and a specific pattern is displayed. CONSTITUTION: In the case a display mode is in a specific pattern, an attacker opening signal for making the attacker favorable for a player for a period of time predetermined according to the pattern is sent from a variable display device controlling section 41 to a motor drive circuit 46 to drive a motor 37 and to open a plate 33. An attacker lamp 36 is repeatedly turned on and off with outputs from the lamp drive circuit while the plate 33 is open. A winning port 84 becomes a V-zone or a winning zone while the lamp is lit up. Therefore, when a struck ball enters the winning port 34, a determination circuit 43 outputs an attacker opening signal for continuing winning. This signal is delayed by a specified time through a delay circuit 44 and sent to the motor drive circuit 46. The attacker plate 33 is closed once from the open state and opened again to continue favorable state for the player.
