Chip's Challenge is an arcade puzzler created by Epyx, with a team lead by Chuck Sommerville, originally for the Atari Lynx console. The game released in 1989 was one of the launch titles.
The game was much more successful than the console itself, and it was ported to several other platforms, including Atari ST, Amiga, Commodore 64, ZX Spectrum, MS-DOS. Most of the conversions were handled by Images Software. Microsoft also released Chip's Challenge in a Windows 3.1 version in 1992.
At first sight, it looks like an 8-bit title converted to 16-bit without improving the graphics, but, despite the simple visuals, the game design is fantastic. Gameplay involves collecting enough chips in the rooms to unlock the level. To do that, you will have to open the doors, using the right keys, avoid traps and enemies. There are 148 levels and most of them are really brilliant. Difficulty increases gradually, with a perfect balance. A useful password system will allow you to continue from the last level you solved, like Lemmings.
If you like a good challenge and you can appreciate an excellent puzzle design, this is the game for you. If you start playing, it's guaranteed that you will find yourself addicted to this small gem.
