Hunt the Wumpus is a fun little game by dreamcodex, where you must find the Wumpus monster, you search the rooms (while avoiding pitfalls) and must guess which room the monster is in. The game has a nice atmosphere and varying difficultly levels to suit you.
[quote]Hunt The Wumpus is a remake of the classical searching game by Gregory Yob. It is heavily inspired by the graphical version released on the TI-99/4A computer.
You play a lone hunter seeking to liberate a village from the predations of the Wumpus. Entering the twisting caverns, you must avoid slime pits and the unpredictable bats in your search. Bloodstains on the floors warn you that the Wumpus slumbers nearby, and when you’ve determined the beast’s location, you have one chance to fire your arrow. Succeed and the threat of the Wumpus is ended. Fail, and you become the next victim of the Wumpus.
