In the two-player card battle game Allies: Realm of Wonder, both players choose two characters to create their own decks. The game is played over four rounds, and during each round the players fight for the Region Cards in the center of the table. Each new Tribe Card that is played changes the situation, and they may have the power to weaken cards of the opponent or strengthen those of the player himself.
A round ends when all slots by the Region Cards have been filled. At that point a fight takes place around each Region Card. The strongest Tribe Card by each Region Card creates victory points for the player. For the next round, new Region Cards are placed, and old Tribe cards are removed. The player with the most points after the fourth round wins.
