<p><P>PROBLEM TO BE SOLVED: To provide a novel game machine capable of increasing the probability of generation of a specified presentation symbol in a special presentation mode called a "mission mode", etc. <P>SOLUTION: In the game machine, a prescribed presentation symbol is selected from a plurality of presentation symbols and a lottery for the shift from a regular presentation mode to a special presentation mode is executed in each lottery for a special prize. When the mode is shifted to the special presentation mode, the prescribed presentation symbol is specified and displayed during the special presentation mode. The rate of selecting the same presentation symbol as the specified presentation symbol or selecting a presentation symbol near the specified presentation symbol is higher than the rate of selecting presentation symbols other than these presentation symbols. In this way, as the probability of appearance of the specified presentation symbol in the special presentation mode called the "mission mode", etc. can be increased, the presentation effect of the "mission mode" can be securely exhibited. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
