<P>PROBLEM TO BE SOLVED: To improve game properties by varying the routes to acquisition of winning balls. <P>SOLUTION: When winning a special symbol in a first game state (a normal mode), and a normal win (a 2R normal win) is determined, and when the kind of a special symbol corresponding to a jackpot pattern where the number of time-saving game is determined to be zero, a second game state (a chance mode) is entered. When winning the special symbol in the first game state or the second game state, and a probability variation win (a 2R probability variation win) is determined, and when the kind of the special symbol corresponding to a jackpot pattern where the number of time-saving game is determined not to be zero, it is configured to enter a third game state (a continuous winning mode), and it is configured to make the probability of changing from the second game state to the third game state higher than the probability of changing from the first game state to the third game state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
