GAME MACHINE

PROBLEM TO BE SOLVED: To enable a change in game property by a shift of a game state, while stably increasing put-out balls by an AT.SOLUTION: A setting is made so that, during an RB operation in a BB operation, a winning probability of small wins as a whole is higher than during a normal state, a BB general, and an RB internal, but a probability to simultaneously win a plurality of correct bells is set lower than a probability to win any one of the plurality of correct bells during the normal state, the BB general, and the RB internal. In a BB1, lotteries for an RB1 and an RB2 are held, and in a BB2, a lottery for an RB3 is held. In an RB2 internal and in an RB3 internal, an AT is performed. When the BB is finished, a shift is made to the normal state, and lotteries for the BB1 and the BB2 are performed.SELECTED DRAWING: Figure 6 【課題】ＡＴにより安定的に出玉を増加させつつ、遊技状態の移行による遊技性の変化を可能とする。【解決手段】ＢＢ作動中のＲＢ作動中は、小役全体の当選確率が、通常状態、ＢＢ一般中及びＲＢ内部中よりも高いが、複数の正解ベルが同時に当選となる確率は、通常状態、ＢＢ一般中及びＲＢ内部中において複数の正解ベルのうちのいずれかが当選する確率よりも低くなるように設定する。ＢＢ１では、ＲＢ１及びＲＢ２を抽選し、ＢＢ２ではＲＢ３を抽選する。ＲＢ２内部中及びＲＢ３内部中においてＡＴが行われる。ＢＢが終了した場合には通常状態に移行し、ＢＢ１及びＢＢ２の抽選が行われる。【選択図】図６
