Imagic

Imagic was an American game developer, based in Los Gatos, California, that produced a subtantial number of titles for early 1980s consoles and computer systems, with primary focus on the Intellivision, Atari 2600, and 8-bit home computers. Composed of former Atari and Mattel employees, the company formed in 1981, shortly before the video game crash of 1983, and folded a few years later in 1986.
