In Scotland Yard; one of the players takes on the role of Mr. X. His job is to move from point to point around the map of London taking taxis; buses or subways. The detectives - that is; the remaining players acting in concert - move around similarly in an effort to move into the same space as Mr. X. But while the criminal's mode of transportation is nearly always known; his exact location is only known intermittently throughout the game.
