Original version The basic premise of
Mouse Trap has been consistent over time, but the turn-based gameplay has changed. Its concept was first invented by
Marvin Glass and designer Gordon Barlow from Marvin's company,
Marvin Glass and Associates, who were later granted a US patent in 1967. The original published version of the game in 1963 was then designed by Hank Kramer of
Ideal Toy Company, filling in the details Glass had left open, and allows the players almost no decision-making, in keeping with other games for very young children such as
Candyland or
Chutes and Ladders (
Snakes and Ladders). Players take turns rolling a die to advance their
mouse piece along a path around the game board, from the start space to a continuous loop at the end. The
Rube Goldberg-like mouse trap is assembled in the center of the board, with players adding one or more of its pieces when they land on specified "build" spaces -- the number on the space has to match the number of players participating. The trap is always assembled in a specified order, and is attached to the board by inserting tabs into holes and locking them into place. The mouse-trapping mechanism works as follows: One player turns a crank, turning two gears and pushing on a lever. The lever whacks a stop sign into a shoe, which kicks a small bucket holding a large ball bearing. The ball bearing rolls down some crooked stairs and into a rain gutter, and then follows the gutter to bump into the bottom of a vertical rod. The top of the rod has a "helping hand" that bumps another ball bearing, making it fall through a "thing-a-ma-jig" and into a bathtub, then out of the bathtub and onto a diving board. This catapults a diver on an arc up and into a washtub, knocking loose a cage suspended from the top of a bumpy rod. The cage rattles down the rod and onto another player's mouse, trapping it.
Revised versions In 1975, the board game surrounding the trap was redesigned by
Sid Sackson, adding the cheese pieces and allowing the player to maneuver opponents onto the trap space. Players collect cheese-shaped tokens during the game, and if the trap space is vacant when they land on the "turn crank" space, the tokens can be redeemed for a die roll to move an opponent. A version of the game featuring characters from the
Elefun and Friends universe was introduced in 2014. Among the changes in this version, the trap is built before the start of the game, a spin wheel is used instead of
dice, and the cheese pieces and their relevant rules are not included. Also, there are three mice named Sneakers, Nacho and Pepper. Also in the 2010s, Hasbro introduced
Classic Mousetrap with several major changes from the previous versions. The object in this game is to collect six cheese pieces. Instead of being eliminated from the game when caught by the trap, a player only forfeits cheese pieces to the opponent. The trap machine was modified, such as with the elimination of crank gears in favor of launching the trap by directly pulling the lever with the plastic stop sign. ==Similar games==
