A faster travel version called "Die Jagd Nach Mister X" exists that functions quite differently. In this version, Mr. X's location is only hidden when a black travel token is used, and the game is essentially an open chase around London. Evasion is accomplished with black tokens and using the fastest travel to distant locations. In this version, each player takes turns as Mr. X, and points collected (in the form of the detectives' used travel tokens) determine the overall winner.
