The Nunchuk is a Wii Remote accessory that gives you an additional means of control in Nunchuk-compatible games. By connecting the Nunchuk to the Wii Remote via a short cable you can benefit from its extra buttons, analogue joystick and additional motion-sensing controls.

With a Wii Remote in one hand and Nunchuk in the other, you have a new level of control. For instance in The Legend of Zelda: Twilight Princess, the Wii Remote is your sword while the Nunchuk is your shield.
