Each player assumes the role of one of the six suspects, and attempts to deduce the correct answer by strategically moving around a game board representing the rooms of a mansion and collecting clues about the circumstances of the murder from the other players. Numerous games, books, a film ("Clue"), and a musical have been released as part of the "Cluedo" franchise. Several spinoffs have been released featuring various extra characters, weapons and rooms, or different game play. The original game is marketed as the "Classic Detective Game", and the various spinoffs are all distinguished by different slogans.
