With the failure change pattern type determination table C, a super ready-to-win flag having a high reliability is determined at a high probability as the change pattern. In addition, when the concealed requirement is accomplished, a lottery for changing performance mode is executed, in which different degree of expectation for shifting to high probability play mode or different performance mode is applied according to type of the change pattern determined upon the change. |
