  • Publication number: 20200023280
    Abstract: When a viewer executes a predetermined present operation, an item is selected from items that are possessed by the viewer, and is given to a player who is selected as a destination. Alternatively, an item that is purchased by the viewer is given to a player who is selected as a destination. When the player uses the presented item, a reward is given to the viewer who provided the present. This can make watching of gameplay images to be more attractive. Further, this allows the viewer to provide assistance more than cheering up to the player who performs the gameplay, and allows the viewer to feel a certain sense of unity with the player.
