<p><P>PROBLEM TO BE SOLVED: To provide a game machine capable of sufficiently attracting game player's amusement at a finish of a state profitable to a player while two-step lotteries are conducted before making a game state profitable to a game player. <P>SOLUTION: In the game machine, unless a game ball wins in an extra-symbol-starting electric generator from determination of a normal winning and a jackpot determination following the prize winning determines a jackpot, a jackpot game is not executed. When the jackpot game finishes, a probability variation time-shortening state or a non-probability variation time-shortening state is generated. During the probability variation time-shortening state, probability with which a normal winning or a jackpot is determined is higher than that in the ordinary state. A non-probability variation time-shortening state is generated when a probability variation state is not generated. When non-probability variation time-shortening state is generated, at least until next jackpot determination is conducted, an opening/closing member of the generator is made easy to open. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
