An object of the present invention is to provide a high-preference game system that can reduce a game development burden of a game system operator, can increase the desire of a player to iteratively play a game, and enables a player to play a game without aversion.
When a player requests a game open in a dungeon, 5 points among the points retained by the player is consumed, and 3 points are temporarily pooled in the dungeon. When the player succeeds in satisfying a clear condition of the dungeon, a total of 13 temporarily-pooled and not pooled points is added to a retention point of the player. Also, when the player fails to satisfy the clear condition of the dungeon, the temporarily pooled points are pooled in the dungeon.
