Abstract: A movement direction of a moving object moving in a virtual space is changed based on at least a component in a first axial direction of a coordinate change of a user's input continuously performed and indicating a coordinate input, with reference to a first reference coordinate point determined by the user's input. A game operation different from a movement of the moving object in the virtual space is determined based on at least a component of the user's input in a second axial direction different from the first axial direction, and is executed.

Abstract: After a game is performed, a lottery process for selecting any content from among a plurality of contents by lot is executed. In accordance with the degree of rarity of the content selected by lot in the lottery process, the number of times of an operation to be performed by a user is set.

Abstract: In an example system, in the first game scene, a first game object is given to a user in exchange for a reduction in in-game currency possessed by the user, and based on a type of the first game object, a player object disposed in a virtual space is controlled. Based on the player object's reaching a specific position in the virtual space, a second game object is given to the user, and based on the user's instruction, the second game object is given to the user in exchange for a reduction in the in-game currency. The first game object is allowed to be continually used in a plurality of the second game scenes, and the second game object is not allowed to be continually used in a plurality of the second game scene.
