PROBLEM TO BE SOLVED: To address uniformity of a game in which a specific winning combination (e.g., a rare small winning combination and a replay winning combination) preset by a producer of a game machine is used as a trigger of an AT (Assist Time) lottery, so that, even when a lottery probability of the AT lottery is improved, a trigger of the AT lottery is not changed.SOLUTION: A game machine includes a plurality of chance zones where winning probabilities of AT are improved more than the normal one and allows a player to select any of the chance zones. A winning combination that turns out an AT lottery trigger of selectable chance zones corresponds to all winning combinations selectable by the internal lottery, so that all of the winning combinations selectable by the inner lottery are subject to a selection in any of the chance zones.SELECTED DRAWING: Figure 20 |
