Mouse Trap was a 1981 arcade game released by Exidy, A fairly obvious Pac-Man ripoff, it was successful enough that it was also ported to three different home game systems ColecoVision, Intellivision and the Atari 2600.
Mouse Trap did at least change up certain aspects of the game from Pac-Man – there were doors that players could open and close, it was possible to store power pills for later use, there were six rather than four hunters, and bonus items were available constantly rather than intermittently. The game had a small but devoted following, however, by 1999, very few of the arcade versions of it were still extant.
