Trivia Master is a color arcade game created by Enerdyne in 1985. The game system was designed by Scott Boden, who previously worked on Star Castle and Solar Quest. The software and graphic design was done by Tim Skelly, who also designed games for Cinematronics, Gremlin and Gottlieb. Trivia Master was designed as a countertop coin operated game, and as a conversion board set for existing upright games. Replacement trivia questions were sold in the form of Eproms that plugged into the mother board. Four sets, or categories, could be loaded at one time.
