Bop It toys are a line of audio games based on concepts originally patented by Dan Klitsner.Bop It was licensed to Hasbro and further developed there by a number of designers including Bob Welch.

Bop It games test players' mental skills by inducing them follow directions at a faster and faster pace. Play consists of following a series of commands issued through speakers by the toy, which has multiple inputs including pull handles, twistable cranks, spinnable wheels, toggle switches, and all versions feature a centrally located large round button that may be pressed to start the game. With newer versions, additional inputs have been added or altered such that units like the 2010 Bop-It! Bounce shares no inputs in common with the original 1996 Bop It (see below).

Bop It has been identified as some of the more popular children's games on the market, and toy and game development researchers have pointed to the natural interactions between player and toy, and the ability of players to use the toy to revert computer gaming processes back into those that resemble non-mediated object play. Other studies have shown that it is the Bop It's ability to mimic engagement in social behavior that has led to its commercial successes.
