The Legend of Zelda Game Watch

Although Nintendo's The Legend of Zelda game series was mostly constricted to consoles and the Game Boy, two "mini" versions were released, the confusingly-named "Zelda Watch Game" and "Zelda Game & Watch".

About the watch
The Game Watch was a multi-purpose wristwatch by Nelsonic. It was based on the original The Legend of Zelda and included such familiar foes as Aquamentus and Keese. It was considered the poorer of the two LCD games because the screen was too small to reasonably allow much strategy or movement. The playing area was even smaller than that of the Game Boy titles in the series. The Zelda watch was sold in the colors pink, black, white or red. There was also a Mario Brothers watch that was made in blue and maybe some other colors. Later in the years, a great number of these watches were sold. Some of the other games was Tetris, Donkey Kong, and Star Fox.

About the game
The game consisted of four dungeons with four rooms each. In each room, Link would have to collect a boomerang to defeat the boulder enemies. After all boulder enemies were defeated he could get a sword to defeat the Keese which first appear in the second dungeon. As a reward, he gained a key to the next room. When entering it, though, he lost his found items and had to recollect them, and if he did not make it to the next room within ten seconds of grabbing the key it was game over. The last two rooms of every dungeon also had Recovery Hearts to replenish Link's health. Once all the enemies in the fourth room were dealt with, the dungeon's boss (which was always Aquamentus) appeared. To defeat him, Link had to collect a bomb and place it in front of Aquamentus. Following his victory, a Triforce fragment would appear, which allowed him access to the next dungeon. After collecting all four pieces of the Triforce the game would reset to level one.
