Mr. X also has a supply of black tokens (one per detective in play or always five in the Milton Bradley version) that can be used in place of any other kind of transport ticket but prevents the type of transport from being visible, and three tokens that allow him to make two moves in a single round. The water routes require a black ticket to use and so when one of these is played the detectives must consider whether or not it is being used to hide a river trip. Mr. X moves first each turn, after which the detectives must move, but they can do so in any order.
