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 a pseudo presentation of opening/closing of a large winning hole without changing the probability of winning the short jackpot, or the like in a jackpot lottery even if the result of the jackpot lottery is a miss as well as the short jackpot or minor jackpot. SOLUTION: In an attacker 100, pseudo opening/closing presentation plates 170 are housed in the large winning hole 112 of a large winning hole plate 110 in such a way as swingable in the vertical direction within respective grooves in a front frame 120 disposed to face the large winning hole from the front side. A left wall 170b and a right wall 170c of each pseudo opening/closing presentation plate 170 are extended rearward through the large winning hole plate 110 in such a way as swingable in the vertical direction to be coupled with a driving mechanism 100c. With this structure, the pseudo opening/closing presentation plates 170 are driven by the driving mechanism 100c to swing in the vertical direction within the respective grooves in the front frame 120, so that the pseudo opening/closing of the large winning hole 112 is presented.
