To enable a game player to pre-recognize how a ball moves along a path.

It is judged whether one of player characters touches the ball or not (Step S1). For example, if the player character touches the ball by centering (kicking) the ball, a moving path of the ball is calculated (Step S2). The moving path calculated in the Step S2 is displayed in a semitransparent color (Step S4). Therefore, the game player can see the displayed moving path of the ball for pre-recognizing how the ball moves along the path. Thereby, the game player can easily and appropriately move the player characters corresponding to the movement of the ball at the time of offense.
