Genco Manufacturing Co., founded in Chicago in 1931 by brothers Louis, Meyer, and David Gensburg, was a pioneering manufacturer of coin-operated pinball machines and arcade novelties, producing roughly 238 titles between 1931 and 1959. Early flipperless electromechanical games such as Buster Ball demonstrated Genco’s inventive pre‑war designs, and after World War II the company adopted electrified flippers—most famously with Triple Action (1948), which helped popularize the modern two‑flipper layout and is often associated with designer Steve Kordek’s innovations. Renowned for cost‑effective, mechanically clever engineering and a catalog of classic tabletop and arcade offerings, Genco competed with contemporaries like Gottlieb and Bally before diversifying and ultimately merging with Chicago Coin in 1959; today Genco machines remain sought-after examples of vintage and electromechanical pinball prized by collectors and arcade historians.
