Mouse Trap, originally Mouse Trap Game, is a board game first published by Ideal in 1963 for two to four players. It is one of the first mass-produced three-dimensional board games. Players at first cooperate to build a working mouse trap in the style of a Rube Goldberg machine. Then, players turn against each other to trap opponents' mouse-shaped game pieces.
