PROBLEM TO BE SOLVED: To provide a Pachinko game machine capable of providing a player with an opportunity to have such a sense of expectancy that the game state may be a short jackpot or minor jackpot game state by adding a mechanical function devised to present pseudo opening/closing of a large winning hole without changing the probability of winning the short jackpot or the like in a jackpot lottery. SOLUTION: In an attacker 100, pseudo opening/closing presentation plates 170 are housed within respective grooves in a front frame 120 disposed to superposably face the large winning hole 112 of a large winning hole plate 110 from the front side in such a way as swingable in the vertical direction. Accordingly, the pseudo opening/closing presentation plates 170 are located to superposably face the large winning hole 112 from the front side. With this structure, the pseudo opening/closing presentation plates 170 swing in the vertical direction within the respective grooves in the front frame 120 to present pseudo opening/closing of the large winning hole 112 at the positions superposed on the large winning hole 112.
