PROBLEM TO BE SOLVED: To improve interest by bringing a game state into a variation time shortening state of being able to simultaneously materialize both impartment of an expectation feeling to a big win and improvement of a consumption efficiency of a symbol variation game.SOLUTION: During a variation shortening state, only a winning variation content forming a ready-to-win condition during a symbol variation game and leading out winning symbols, and a losing variation content leading out losing symbols without forming the ready-to-win condition during the symbol variation game can be selected. As a selection ratio of selecting the losing variation content during the variation shortening state, a ratio of selecting the losing variation content (a variation pattern HP1) having a shorter variation time than the losing variation content having a shortest variation time capable of being selected in a non-variation shortening state is enhanced when at least one start held ball remains when selecting the variation content (a holding storage number "1-3" of Fig. 8(b)). |
