4.5 A great accessory for Wii games which require it. Caramon | 02/08/2011 | See all Caramon's reviews (77) The Nunchuk is a Wii accessory used in an ever increasing number of games. Extremely light, it is basically a joystick control with two buttons (marked C and Z) which sits snugly in the hand and is a joy to use. It has an extension cord which clips securely onto a Wii Controller, and in games which require Nunchuks to play, each Controller will need one attached.An extension to the main Controller, the Nunchuk is a valuable accessory which will enhance your gameplay experience tremendously. No separate batteries are required by the Nunchuk, as it draws minimal power from the Controller it is attached to. Available in black, white, red and blue to match the colour of your Wii Console and Controllers.
