Mysterium is a cooperative deduction game for 2 to 7 players, where one player takes on the role of a ghost and the others are psychics attempting to solve the mystery of the ghost's murder. Set in a haunted mansion, the game involves interpreting visions from the ghost, who communicates only through illustrated cards. Over seven rounds, players must deduce the correct suspect, location, and murder weapon through these cryptic visions. If the players correctly identify all elements by the final round, they win and the ghost finds peace. Mysterium is praised for its atmospheric artwork and engaging gameplay.
