IPC: A63F7/02
Filed: 2008-02-26
Abstract: <P>PROBLEM TO BE SOLVED: To arouse a player's consciousness of participation in a game by suppressing a gap from being developed in performance contents due to a difference in continuous operation speeds of players operating a performance operation means.  <P>SOLUTION: When a total variation reaches a prescribed variation in an operation performance giving a change in the performance content whenever a player pushingly operates a performance button, the game machine executes a super ready-to-win performance having a higher expectation degree becoming a jackpot than a case of non-reaching there. An integrated control CPU sets a measurement-available period and measures (computes) a continuous push speed of the player, selects a performance pattern where, as the measured continuous push speed is higher, the variation which is given to the content of the operation performance whenever the player pushes down the performance button, becomes smaller, while selects a performance pattern where as the continuous push speed becomes slower, the variation becomes larger. The game machine can thus execute the operation performance based on the selected performance pattern, according to the set performance-available period.  <P>COPYRIGHT: (C)2009,JPO&INPIT
