Abstract: A given content list stores information about a content that has been given to a player. When a prize content selected by a lottery has been registered in the given content list, it is determined that the prize content satisfies a duplication condition, and an alternative content is selected from an alternative content list, and given to the player instead of the prize content selected by the lottery. An alternative content notification screen that notifies the player that the alternative content has been given to the player is displayed.

Abstract: An input direction determination system includes an input direction determination section that determines the input direction based on a reference point and the indication position, and a reference point change section that determines whether or not to change the reference point based on an angle formed by a first direction that is determined by the reference point and an indication position at a first timing or a timing that precedes the first timing, and a second direction that is determined by the indication position at the first timing and an indication position at a second timing that follows the first timing, or an angle formed by connection lines that connect indication positions at different timings, and changes the reference point.

Abstract: When a cube has been selected, and a touch operation has been canceled, a retouch determination area that is larger than the original selection area for selecting the cube is set based on a touch cancellation position. When a retouch operation has been detected within the retouch determination area after the touch operation has been canceled, it is determined that the same position as the touch cancellation position has been retouched, and the cube (object) is moved.
