Trog is a maze arcade video game developed and published by Midway Manufacturing in 1990 in North America under the "Bally/Midway" label and later by Williams Electronics in Europe.

Initially envisioned as a hybrid puzzle/strategy game, its original concept was later reworked into a Pac-Man-like title after bad reception from testers and features claymation graphics, advertised as "Playmation" by Midway.

The power-ups randomly spawn to help finish the level; these include red flowers that increase the player's speed; ice cubes that freeze all on-screen Trogs; pineapples, which turn the character into a full-grown T-Rex and temporarily eat Trogs (similar to Pac-Man's Power pellets, except the power-up occurs randomly); and a firebrand which bestows a temporary fire breathing ability on the dinos.

[2][4] The multiplayer mode consists of two to four dinos on the same screen competing to get all of his/her same-colored eggs first, and players can either attack or protect each other (though power-ups indiscriminately hurt anyone that is in the way regardless).

Trogs can be one-hit punched, to the side of the head, as they approach the screen edge resulting in them falling into the sea, with bonus points rewarded to the player.

[3][5][6][7] George Petro and Kurt Mahan worked as programmers, with composer Chris Granner scoring the soundtrack and created the sound effects.

[6][7] The original concept, dubbed "Revision 4.00", was more of a puzzle/strategy game consisting of players controlling a hand which would lay bones to guide their corresponding dinosaur in the right path.
