 Just like all other Yu-Gi-Oh!series, Zexal also places a major emphasis on bonds and friendship.The gameplay gimmick introduced in Zexal is "AR Duels" ("Alternate Reality Duels"), in which both players utilize a high-tech monocle known as a "Duel Gazer" to observe a virtual reality where the Duel Monsters interact with the environment, as if they exist in a parallel world of their own.
