An in-terminal display device causes at least one first icon to appear and displays the at least one first icon in at least one of a plurality of areas. An in-terminal input device receives an operation of switching areas and an operation of selecting a first icon. An in-terminal controller or an in-server controller controls a game corresponding to a selected first icon such that the game can be played when any one of first icons is selected in a switched area. The in-terminal controller of the in-server controller limits the number of first icons to be caused to appear to an upper limit value or less.
