An estimated trajectory 281a, an estimated ball landing point 282a, and an estimated run range 283a are displayed in a game image 20a. The estimated ball landing point 282a is displayed as, for example, a star mark, in a game space of the game image 20a which corresponds to a terminal coordinate point on the estimated trajectory 281a. The estimated trajectory 281a is obtained for a shot at a power indicated by a power target value set by the player, and is displayed so as to extend between a current ball 22 and the estimated ball landing point 282a based on estimated trajectory data. The estimated run range 283a is displayed in the game space of the game image 20a based on estimated run range data, so as to have a shape of a rectangular area, which is divided into a plurality of equal-sized mesh parts, in accordance with geographic undulations.
