<p><P>PROBLEM TO BE SOLVED: To prevent a player from being bored in a game by increasing expectation for a hit mode. <P>SOLUTION: When a rewriting is made less than ten times by a hit mode counting part, the number of times (two times) of reduction among the number of times (fifteen) of opening a big winning port through the hit mode is added to the number of times written in a reduction condition memory part, and the number of times summed is written into the reduction condition memory part. The big winning port is opened thirteen times in the hit mode. When the tenth rewriting is executed by the hit mode counting part, the number of times (twenty) stored in the reduction condition memory part stores is read out. In the hit mode, the big winning port is opened by the number of times (thirty five) obtained by adding the number of times (twenty) written in the reduction condition memory part to the number of times (fifteen)determined in advance. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
