PINBALL GAME MACHINE

To further enhance interest in a game of a time-shortening game.SOLUTION: A time-shortening flag and a time-shortening counter is cleared (steps S912 to 913) and specific time-shortening is completed when a jackpot lottery is won during specific time-shortening, or when a losing pattern of a special 2 is determined to be a losing pattern 2 (affirmative determination of step S911) during a specific time-shortening game (affirmative determination of step S910) in cases other than when the number of time-shortening times is consumed. Although a lot of 200 pieces of specific time-shortening are generated when a losing pattern 2 of special 1 is selected, a probability of selection of a losing pattern 2 of a special pattern 2 is set to 2/300, and is set to be higher than a probability 1/300 of selection of a losing pattern 2 of special 1. Accordingly, a probability of forcibly ending specific time-shortening is increased so as to prevent an increase in the average number of time-shortening times because of the specific time-shortening.SELECTED DRAWING: Figure 28 【課題】時短遊技の遊技興趣を一層高めることを目的とする。【解決手段】特定時短中に大当り抽選に当選したとき、又は時短回数を消化したとき以外でも、特定時短遊技中に（ステップＳ９１０の肯定判定）、特２の外れ図柄が外れ図柄２と判定されると（ステップＳ９１１の肯定判定）、時短フラグ及び時短カウンタはクリアされ（ステップＳ９１２～９１３）、特定時短は終了する。特１の外れ図柄２が選択されたときには時短回数が２００回と多い特定時短を発生させるが、特２の外れ図柄２が選択される確率を２／３００とし、特１の外れ図柄２が選択される確率１／３００より高くしている。これにより、特定時短を強制終了させる確率を高くして特定時短による平均時短回数を多くさせない。【選択図】 図２８
