An international super-spy, so secretive that he is only known as Mr. X, is detected in London, and Scotland Yard is on the hunt. In the game Scotland Yard, one player takes the role of Mr. X and the others take the roles of the detectives on the chase. Mr. X leaves small clues to his whereabouts as he moves by bus, taxi, or underground. To deaden his trail, Mr. X can take advantage of his limited supply of "black tickets" and move in secret. The vigilant members of Scotland Yard must deduce the location of Mr. X by his mode of transportation and occasional sightings before he can escape the city.
