Sleuth

This one won't take more than five minutes to play, has one playable board, and consists of running around threadbare rooms looking for clues and getting messages from murder suspects. In order to win, the player must use the process of elimination to find a murderer before a time limit elapses.

Some thought is required, I guess, but the sticking point is finding the murder weapon, which requires doing two things in sequence. Since the time limit is tight, that might be a problem.

File this under "Games that clearly show their extreme age." The writing is weak, but at least the game tried something sort of original - a kind of ZZT CLUE-lite.
