<P>PROBLEM TO BE SOLVED: To prevent a fall in an operation rate regarding a game machine for use in a game parlor such as a Pachinko parlor. <P>SOLUTION: The winning probability of a freeze lottery during a BB mode is set to a low probability when the occurrence frequency of freeze rendering in a normal mode is zero time, to a medium probability when the occurrence frequency of freeze rendering in the normal mode is one to three times and to a high probability when the occurrence frequency of freeze rendering in the normal mode is four to seven times. A probability of shifting to an ART mode thereby becomes higher with the increase of the occurrence frequency of freeze rendering in the normal mode. When the occurrence frequency of freeze rendering in the normal mode is eight or more times, the winning probability of a freeze rendering lottery is set to 1/1 in a first game during the BB mode. A shift to the ART mode after the end of the BB mode is thereby determined. <P>COPYRIGHT: (C)2012,JPO&INPIT |
