PROBLEM TO BE SOLVED: To provide a game machine allowing a player to easily recognize the stage of step-up advance notice presentation of a plurality of systems. SOLUTION: A presentation controlling CPU 101 can execute the advance notice presentation to gradually change the mode of presentation from the first stage to a plurality of stages according to a predetermined order. The presentation controlling CPU can execute a first step-up advance notice presentation and a second step-up advance notice presentation with a high probability of executing the advance notice presentation to gradually change the presentation mode to more stages when a jackpot is made than when a jackpot is not made. The first and second step-up advance notice presentations can be simultaneously executed in the same period during the variable display. The advance notice presentation is changed at the same timing in the first and second step-up advance notice presentations. COPYRIGHT: (C)2009,JPO&INPIT |
