Abstract
A game system includes a game processing section that performs a game process, a lottery processing section that sets a lottery range that specifies a range of items among a plurality of items used during the game process that are subjected to a lottery process, and selects an item from the items that belong to the lottery range by performing the lottery process, and an item acquisition processing section that performs a process that allows a player to acquire the selected item. Information about the plurality of items has a data structure in which the plurality of items are linked to have a parent-child relationship. The lottery processing section sets the lottery range so that a child item is included within the lottery range when a parent item has been set to an acquired state or an acquirable state, and changes the set lottery range based on given information.
