Cluedo is a classic board game where players try to solve a murder mystery. The game is set in a mansion, and players take on the roles of different characters, each with their own unique background. The objective is to determine who committed the murder, with what weapon, and in which room. Players move around the board, collecting clues by making suggestions and eliminating possibilities. The game includes various characters like Miss Scarlet, Professor Plum, and Mrs. Peacock, as well as weapons such as a candlestick or a revolver. The first player to correctly deduce the solution wins the game.
