<p>PROBLEM TO BE SOLVED: To further improve interest of a player by executing a special performance with proper frequency and executing it in timing difficult to be recognized by the player.SOLUTION: A game machine sets a performance counter to be an initial value (100 times) with occurrence of a probability variation big win in an electric support-absent low probability state (the occurrence of the probability big win in a "first win") as a trigger (S600-S604), and does not reset the performance counter to be the initial value even if the probability big win occurs in an electric support-present state or a high probability state or a normal big win occurs. The game machine updates (reduces, a value of 1 by a value of 1,) the performance counter every time a symbol variation game is executed, and executes a special performance in which a variable display time of the symbol variation game is shortened as compared to before the performance counter reaches a prescribed value (a value of 0) until transferring to the low probability state from the high probability state when the performance counter reaches the prescribed value.</p> |
