Official Wii Nunchuk Controller - Wii Mooch

In several games, players will use the analog stick of the Nunchuk controller to move their characters and the Wii Remote controller to perform a game specific action, whether that's throwing a pass in football or aiming a ranged weapon in an action game. Along with the analog stick, the motion-sensing Nunchuk controller also contains two buttons positioned for quick access.

Because the Wii Remote and Nunchuk controllers are only relatively dependent on each other, players are free to hold them in whichever hand is most comfortable. The ambidextrous nature of the Wii controllers grants accessibility seldom seen in game controllers.
