Chip Challenge. Chip's Challenge is a tile-based puzzle game designed by Chuck Sommerville, a game best known for having been free on IBM PCs as part of various Microsoft entertainment packages that came with early versions of Windows. In fact, the game existed a little earlier, as it was originally produced for Atari's Lynx handheld console and published by Epyx. While it features a slightly different engine, slightly different graphics, and has a slightly smaller game area to work with, the original is just as addictive and entertaining as the later version and is, without a doubt, one of the best titles in the library.
