<P>PROBLEM TO BE SOLVED: To provide a technique which can effectively achieve a new performance changing in accordance with an operation of a player. Ž<P>SOLUTION: In accordance with a result of an internal drawing, an operation performance which gradually progresses in accordance with a play progressing operation by the player and a time performance which gradually progresses with an elapse of a prescribed time are carried out at the same time. When the time performance reaches a prescribed step, a progress speed of the operation performance relative to the time performance is decided. When the progress of the operation performance is slower than the time performance, an arrival of the time performance to a final step is delayed. When the progress of the operation performance is faster than the time performance, the arrival of the time performance to the final step is accelerated. Thus, since the progress pace of the operation performance to the time performance irregularly changes in accordance with the operation of the player, the new performance changing in accordance with the operation of the player can be achieved. The progress of the time performance is adjusted to the operation performance, so that both the performances may be effectively compared with each other. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
