Abstract: To provide a game machine capable of suitably improving amusement of games.SOLUTION: A precursory state occurs where a precursory presentation is performed over a plurality of games on the basis of a winning in a lottery of a shift chance trigger combination in a state not in a normal AT state. After a shift chance precursory state is finished, a shift is made to a shift chance state where a shift to the normal AT state may occur, but after a pseudo precursory state is finished, a shift is not made to the shift chance state. In this case, even if an occurrence of the precursory state is won in a lottery while the pseudo precursory state is in progress, the pseudo precursory state in progress is still continued, but the number of continuation games is stocked in the precursory state in accordance with the winning in the lottery for the occurrence. Further, if an activation of the shift chance state is won in a lottery during the pseudo precursory state, the number of continuation games in the shift chance precursory state in accordance with the winning in the lottery for the activation becomes the number of games obtained by subtracting the number of residual games in the pseudo precursory state in progress from a maximum number of continuation games in the shift chance precursory state.SELECTED DRAWING: Figure 9
