Zelda Game & Watch was first released by Nintendo in 1989 as a multi-screen game and watch. In this adventure, he must climb to the top of a skeleton (Stalfos) infested dungeon to reach the Triforce. At the end of each level you must fight a boss before being rewarded with a piece of the Triforce. Along the way he can pick up and use items to help him, such as the Water of Life, a map, and a Tomahawk. If you fall or get hit by a Stalfos the game's over, however there is a continue feature. The game had three levels in total.
This game is one of the first Zelda games to be released with the gamer playing as Link. This game is now considered to be a cult classic, with some units now fetching up to $400. It was re-released in 1998 as a Nintendo Mini.
