There is a Clue game that you can download from a link that I will give you. You open the game  and play it the same way as the board game.  You figure out who committed the murder, what weapon was used and the location of the crime scene.  This game lets you travel from room to room in the mansion, collecting the clues, and also you give clues, and other players will too, until someone guesses who did it.  Every time you play, use a different mode, so that the outcome will be different.  You can play against the computer too.  Here is the link: http://www.ehow.com/how_2100004_play-clue-online.html.
