PROBLEM TO BE SOLVED: To display with performance a notification of a probability varying state while preventing a fraudulent act. SOLUTION: This Pachinko machine 1 does not notify a player whether or not being in the probability varying state after a big win in an initial state and, when the player pushes down a probability variation display button 23, displays the performance of the probability varying information. The player can thus know whether or not being in the probability varying state at a timing desired by himself/herself. When displaying the probability varying information, the performance is displayed in a prescribed mode. This machine can perform a lottery whether or not being in the probability varying state in such a manner as allowing the player himself/herself to feel performing the lottery and allowing the player to have high expectation to turning into the probability varying state or not. The machine also allows the player to have a chance of having the expectation except for the big win lottery result. COPYRIGHT: (C)2004,JPO
