Four Nations is a two-player tile game. Each player randomly selects five tiles from a pool of all the tiles currently available to him or her. These tiles have two of the symbols of the four nations on one side, or a special black Avatar tile, which acts as a wildcard. The game is played by villagers in order to win items. Sometimes the items are tiles themselves, either doubles or the Avatar tile, which Aang adds to his inventory to be used in later matches.
