The Adventures of Robby Roto! (Robby Roto for short) is a 1981 arcade game designed by Jay Fenton, and produced by Bally/Midway.
Robby Roto was unsuccessful, selling less than 2,000 units and much less popular than contemporary Dig Dug. Its developer claimed “it was a very complex game and those who played it found themselves on the defensive — most were intimidated. Gamers like to be aggressive.”
