- 1983 Spiel des Jahres Winner
Which player will have the roll of the elusive Mister X? One player will function as Mister X, with the other players being Scotland Yard detectives searching for him throughout Central London. The starting station cards are shuffled and everyone draws one to determine where they will start the game. Every move is either by taxi, underground, or bus. Mister X moves first and writes his move in his travel log, indicating what method of transportation he used but not where he moved. Then, each detective makes their move, cooperating with the other detectives in an effort to close in on Mister X. But, if Mister X makes 24 moves without being caught, he himself wins!
