Zoop is a puzzle game developed by Hookstone Productions and published by Viacom New Media.

Official Zoop games have been released for Game Boy, Game Gear, Mega Drive/Genesis, Super NES, Atari Jaguar, Sega Saturn (in Japan only), PlayStation, MS-DOS, and Macintosh.Zoop was one of four games played in the Blockbuster World Video Game Championship semi-finals on August 21, 1995, a rare instance of an as-yet-unreleased game being used in the competition. To spark interest for the game, Blockbuster offered the game as a free rental for the Super NES for a limited time.
