Considered by toy collectors as the "holy grail" of monster related games, Monster Lab is a two players game produced by Ideal in 1964. The idea of the game was that players would twist the dial on the "monster control panel" at each end of the lab, in a attempt to keep "the monster" away from their end of the lab. The monster moves up and down the lab, until it reaches one end, when it raises its arms, lets out a growl and his mask falls off, revealing his hideous face beneath. Sounds and looks really cool. However apparently the game play really sucked, and the game was one more of chance than of skill.
Kids quickly got bored of playing the game, and Ideal soon ceased production. Hence why the game is so rare to find, and so collectible. So collectible in fact that mint condition versions of the game have sold for thousands of dollars at auction. The game sold originally for $16, and made its first appearance on the Magilla Gorilla TV show in 1964. It was also featured in the December issue of Popular Mechanics that year.
