Document 15: Gumball (video game): Gumball is a 1983 video game by Robert Cook and Broderbund in which the player controls the valves of a maze-like machine to sort gumballs by their color. The player meets the quota of each level to earn their character—a factory worker—a promotion, resulting in a raise in difficulty with more color choices and defective gumballs to exclude. Broderbund co-founder Doug Carlston conceived of the game's machine-sorting concept, and Cook, the designer, added the gumball conceit and built the core gameplay within a week. He later returned to add sound, decorative features, and a secret image that was only found three decades after the game's release. "Gumball" debuted at the June 1983 Consumer Electronics Show and released for the Apple II, Atari 8-bit family, and Commodore 64. Reviewers separately noted the difficulty of the game's later stages, praised its comical elements, and commented on the social role of simulating mundane work. The game did not become popular and its copies became rare.
