To enhance the interest by comparing data, which correspond to and are allocated to at least two image patterns selected from among several image patterns displayed on a display part, in a game such as a 'nervous break down game', with one another, and by displaying the result of the comparison.

When a card game process is started by manipulating a key input part 12, ten of several music initiating addresses are randomly selected. Thus selected ten music initiating addresses are stored in memory, each corresponding to random two of twenty card icon arranging positions. Further, a card icon selecting screen is displayed as a nervous breakdown screen having four in the longitudinal direction and five in the transverse direction. Further, when two image patterns are selected, data allocated corresponding to the image patterns are compared with each other, and the result of the comparison is delivered.
