"Loopz", designed by Ian Upton, is one of the few computer games to have been converted to a coin-operated arcade game, and whilst Capcom (the licensee) never brought the game to market, a video of the completed game exists. It was also licensed to Barcrest for release as a skill-with-prizes amusement machine, but this version also failed to make it to market. However versions were released for 18 different computer and video game formats including NES, Game Boy, IBM PC, Amiga and Atari ST. A follow up game, "Super Loopz", was licensed to Imagineer for the Super NES and was published for the Amiga by Audiogenic.
