How many Zelda games are there for wii?

Only one, Zelda: Twilight Princess. However, because the Wii is backwards compatible with the Nintendo GameCube and Nintendo put the following games on a gamecube disc, The Legend of Zelda: Majora's Mask and Ocarina of Time, may be played. In addition, Windwaker and Four SWords Adventures may be played with a Wii as well. Note: Link's Crossbow training is also for wii, and is a Zelda spin-off. Some people would count this, others wouldn't.
