PROBLEM TO BE SOLVED: To prevent taste of a game becoming monotonous by varying expectation degree for an internal high probability state, such as a "hidden probability variation" hidden to a player, into a plurality of ways.SOLUTION: A 2-round probability variable big win and a 3-round probability variable big win opening a large winning hole the different number of times are provided as winning types of internal lottery executed in a Pachinko machine. Also 2-round probability non-variable big win and a 3-round probability non-variable big win with the same opening counts are provided. A selection ratio is differently set between the 2-time (2-round) probability variable big win and the 3-time (3-round) probability variable big win, and the selection ratio is also differently set between the 2-time (2-round) probability non-variable big win and the 3-time (3-round) probability non-variable big win. Consequently an arrangement is possible, for example, when the number of door opening (the number of rounds) increases in a performance, reliability of a probability variable jackpot also increases proportionally. |
