Title: Game machine
Inventor: HIROSE MASASHI
IPC: A63F7/02
Filed: 2000-12-19
Abstract: PROBLEM TO BE SOLVED: To implement a pattern fluctuation, which is different from that at a limiter non-operation, at a limiter operation and to clearly inform a player of a fact that the limiter is operated at the limiter operation. SOLUTION: When only a different fixed pattern fluctuation pattern or a specific fluctuation pattern appears at a high probability or at a fluctuation time shortening function operation, the limiter operation can be reported (notified) to the player even at the high probability or at the fluctuation time shortening function operation. Since it is clearly reported that no big bonus can be gained by specific patterns, a speculative spirit is prevented from being wastefully incited. When a limiter is found, it is guaranteed that the next big bonus has no specific patterns, therefore a hall worker can efficiently prepare a dollar box (box for storing Pachinko balls), and man power can be saved.
