PROBLEM TO BE SOLVED: To secure an appropriate base by providing a combination change means for changing the combination of a winning pattern for establishing a point based on winning/losing judgement. ;SOLUTION: At the end of one game (S51: YES), when an inhibition flag F is not '1' (S52: NO), whether or not it is high probability is judged (S53). The value of a table 5 is read (S54) at the time of the high probability (S53: YES) and the value of the table corresponding to the value of a random number Rd read in a random number obtaining routine is read (S55) when it is not the high probability (S53: NO). A numeral corresponding to the number of the table is displayed on a selected pattern display device (S56), a liquid crystal controller is instructed and the arrangement of a numerical pattern corresponding to the already read table is displayed on a winning pattern display part (S57). Thus, without being influenced only by the constitution of the nail arrangement or the like of a game panel, the appropriate base can be secured and a player is prevented from being one-sidedly disadvantageous and from playing while expecting only the winning of a winning/losing judged result.;COPYRIGHT: (C)2000,JPO
