Chip 'n Dale Rescue Rangers: The Adventure in Nimnul's Castle is an MS-DOS game based on Chip 'n Dale Rescue Rangers.

Gameplay

The player controls Chip helped by Dale (automatically controlled by computer), who break through the obstacles made by Professor Norton Nimnul. The Rangers go through 9 levels to save Monterey Jack, who has been caught by a mousetrap in Nimnul's castle.

On the first 3 levels, Rangers must get to Nimnul's castle jumping in and out of pits, avoiding the running dogs and falling acid drops thrown by Nimnul himself.

On the second 3 levels, Chip must avoid fire throws from candles, collect screws, and give them to Dale as he runs away from dogs.

On the third 3 levels, Chip must avoid the machine with hands, collect screws, and give them to Dale running away from dogs.

Between levels the animation is shown on how the player progresses in the game, such as, for example, Zipper transfer the screws collected by Rangers for the flying machine Gadget is repairing.
