GAME MACHINE

PROBLEM TO BE SOLVED: To provide a game machine having a favorable operation relationship between a large winning hole and a distribution part.SOLUTION: After an opening/closing plate 650b executes a prescribed operation, if a state of a flow-down prevention plate 5015 is an operation mode of becoming a projection state that is advantageous to a player, the player can easily acquire the state of the flow-down prevention plate 5015 by just checking whether or not the operation mode of the opening/closing plate 650b becomes the prescribed operation. However, when the state of the flow-down prevention plate 5015 is changed by the number of times of state change of the opening/closing plate 650b, even when the mode (the operation mode) of the state change of the opening/closing plate 650b is exactly the same, an influence exerting on the flow-down prevention plate 5015 is completely different by what time of the state change it is within the reference number of times. Consequently, this configuration can provide such a game property that the flow-down prevention plate 5015 becomes the projection state that is advantageous to the player without any advance notice.SELECTED DRAWING: Figure 39 【課題】大入賞口と振分部との動作関係の良好な遊技機を提供すること。【解決手段】開閉板６５０ｂが所定の動作を行った後に流下防止板５０１５の状態が遊技者にとって有利な突出状態となる動作態様であれば、遊技者は、開閉板６５０ｂの動作態様が所定の動作になったか否かを確認すれば良いので流下防止板５０１５の状態の把握が容易であるが、開閉板６５０ｂの状態変化の回数により流下防止板５０１５を状態変化させる場合、開閉板６５０ｂの状態変化の態様（動作態様）は全く同じものであっても、それが基準回数の内の何回目の状態変化なのかで、流下防止板５０１５へ及ぼす影響は全く異なる。そのため、流下防止板５０１５が、前触れ無く、遊技者にとって有利な突出状態となるという遊技性を実現することができる。【選択図】図３９
