Chip's Challenge (Windows)

Chip's Challenge
Developer: Microsoft Publisher: Microsoft Platform: Windows Released internationally: September 14, 1992 This game has unused objects.

Chip is willing to do anything for Melinda the Mental Marvel - more than anything, actually, because he wants to join her exclusive computer club the "Bit Busters". Melinda offers him membership on one condition: Chip must find his way from one end of her magical clubhouse to the other, picking up cosmic computer chips along the way.

To do: Revisional differences. Some copies of the game have a wall removed on Level 88.

Unused Tiles

Tile indexes 54, 55, and 56 go unused in the Windows version. They appear to be copies of the used "invisible wall" tile (index 5).
