<p><P>PROBLEM TO BE SOLVED: To enable one to have an interest in which specific game state has a higher occurrence frequency in a special game state by changing an occurrence frequency between a first specific game state and a second specific game state having different degrees of advantage in control to the special game state. <P>SOLUTION: In selection of a second special symbol variation pattern, a CPU 56 selects a second special symbol variation pattern table for selecting a variation pattern having variation time shorter than that of a first special symbol variation pattern at a predetermined ratio in a first selection state (first time-shortening state), and selects the second special symbol variation pattern table for selecting a variation pattern having variation time shorter than that of the first special symbol variation pattern at a ratio higher than that of the first selection state in a second selection state (second time-shortening state). Thus, an occurrence rate of a jackpot in a second special symbol is increased in stages. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
