PURPOSE:To allow an unexperienced player to know that big hit condition is generated easily by generating effective sound by a speaker during an initial condition generation waiting time until a special variable prize unit is changed at the first time when a specified mode is generated in a variable display unit. CONSTITUTION:In the case where counters CNT1-CNT4 are operated with generation of specified award (with ON of switch SW1 or SW2) and operation thereof is stopped with a signal of stop switch SW3, when the value of any one of counters is in correspondence, it is detected by a judgement circuit DCD and semi-hit signal C2 is generated. Then, the signal is supplied to an effective sound generation circuit SG to form a drive signal which generates a correspondent effective sound, and it is amplified by an amplifying circuit AMP and fed to a speaker SPK to generate an effective sound, and further display lamps L1, L2 repeat a quick ON/OFF operation in synchronization with a clock CK4. A semi-hit signal is fed to a driver DR6 to drive a solenoid SOL to open a variable award unit. |
