Some minigames allow players to team up against opponents, either in symmetrical 2-on-2 minigames or asymmetrical 1-on-3 minigames, and some minigames have only two players competing against each other, called Duel minigames. The goal is to perform the best out of opponents within each minigame rule and controls, which are briefly explained prior to playing the minigame. Players use Nintendo 3DS capabilities to perform actions, such as tapping objects with the touch screen, blowing into the mic, or using the gyroscope to balance or steer objects, though most minigames use the traditional buttons and control stick format.
