<p>PROBLEM TO BE SOLVED: To achieve game property where significance of a small win is effectively improved for a player.SOLUTION: The number of prize balls with respect to the entrance of a game ball in a second start port is set to be smaller than the number of prize balls with respect to the entrance of a game ball in a first start port, but the probability of the second win/loss lottery to be a small win is set to be higher than the probability of the first win/loss lottery to be a small win. As a variable pattern selection standard to be referred to in order to determine the variable pattern of a second special symbol during the shift to a ball entrance easy state after the result of the first or second win/loss lottery has become a big win, variable pattern determination means includes: a normal variable pattern selection standard; and a special variable pattern selection standard to be referred to when the result of at least the second win/loss lottery has become a specific result during referring to the normal variable pattern selection standard. In the special variable pattern selection standard, the variable time of a variable pattern to be selected when the result of the second win/loss lottery has become a small win or loss tends to be shorter than that of the normal variable pattern selection standard.</p> |
