IPC: A63F7/02
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To happily play a game by deciding a second privilege by a game a player plays. SOLUTION: Concerning a pinball machine such as a pachinko machine giving a first privilege to the player when a big winning occurs during a game, a privilege deciding game is played during a big winning game or a normal game. This privilege deciding game is realized by privilege deciding processing, etc. When a game ball enters or passes through (YES in a step 94) a gate (game device), the number of period reducing times (a second privilege) is counted up (step S96). Thus, within a privilege deciding game period (step S98), the number of period reducing times is decided according to the number of game balls entering or passing through the gate. Since the second privilege is given by the result of the privilege deciding game the user plays, the player can obtain more prize balls. Consequently the player can play happily.
