Filed: 2020-03-24
Abstract: To provide a technique in which a performance mode during read-ahead can be changed.SOLUTION: A performance control unit 210 accepts the change of a performance mode when a change operation of the performance mode during variation display of a special symbol is detected (Fig. 69), and continues a read-ahead performance during execution while discarding all the read-ahead information when receiving a performance command when the number of operation memories decreases (Fig. 65). When a read-ahead performance discard message is set at the start of the next variation (S924), the read-ahead performance excluding a winning notification lamp 60 is all canceled by operations of a liquid crystal display, a speaker and a lamp being controlled according to the message by each individual control unit 220, 222, 224. The performance control unit 210 constructs a background image according to the performance mode of the change destination at the start of the next variation (S926). With such a configuration, the performance mode during the read-ahead performance can be changed. Since the read-ahead performance by the winning notification lamp 60 is continued, it is possible for a player to enjoy the game without giving the player a sense of distrust.SELECTED DRAWING: Figure 68
