<p><P>PROBLEM TO BE SOLVED: To provide a game machine capable of retaining fairness of a game by making it hard for a player to recognize the appropriate timing for shooting game balls with presentation. <P>SOLUTION: In the game machine, a game ball cannot enter a special symbol-starting electric generator unless the special symbol-starting electric generator is opened based on determination of a regular jackpot. When a game ball enters the opened special symbol-starting electric generator, the jackpot determination is executed for the first time in that stage. The special symbol-starting electric generator is opened when demonstration symbol variable display presentation suggesting the regular jackpot is terminated. A plurality of specific presentation patterns to be determined when the regular jackpot is determined are included in regular symbol variable display patterns for determining the content and presentation time of the demonstration symbol variable display presentation. The plurality of specific presentation patterns have the same presentation content, different from one another in the presentation time only. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
