If you like mysteries, you will like playing Milton Bradley's Clue Boardgame. This was one of my favorite games as a kid.
You have a cool board showing off nine interesting rooms in a mansion, like the conservatory and library. You have six weapons that the murderer could have chosen to wipe his victim off the planet. You have six suspects that all look as guilty as heck. So whodunit? It's up to you, the gameplayer, to find out.
Each person has a game piece that is color coordinated with one of the suspects, such as Colonel Mustard is yellow, Miss Scarlet is red. It is lots of fun to move from room to room in this house.
The big fun happens when you get to accuse someone of being the murderer. By process of elimination, you describe who did this crime, where it happened, and what weapon did the criminal use.
You do need at least 3 players, or there is no point in playing.
This is one of the best games ever.
