Abstract: PROBLEM TO BE SOLVED: To enable a player to have expectations toward a high winning probability of a lottery without causing loss to a Pachinko parlor.SOLUTION: A Pachinko machine reads a setting switch, and determines probability setting for determining a winning probability in winning/losing determination of a special pattern when a RAM is cleared on power-on. Although the Pachinko machine executes a read-ahead performance for suggesting a result of the winning/losing determination by displaying a read-ahead reserved pattern in accordance with holding storage, the Pachinko machine executes a setting change performance for suggesting a change in probability setting (change in setting) by changing the read-ahead reserved pattern displayed by the read-ahead performance. The setting change performance is executed at a different frequency between when a setting change advantageous to a player is performed and when a setting change not advantageous to a player is performed (S520, S525).SELECTED DRAWING: Figure 12
