TacDex uses gameplay similar to well-known card game War, with players revealing cards simultaneously to try to claim cards owned by the opponent, but a battle marker determines whether a high or low card wins a particular battle and players each have special action cards to add new twists to the conflict.
In the Super Mario Brothers edition, players duel to the finish with their favorite Super Mario characters.
