Editing Scotland Yard (board game) (section)

===Movement===
Movement is governed by using transportation tokens ("tickets"), which allow passage between spaces according to the following modes:
* [[Taxicab|Taxi]]s, which allow the player to move only one space per turn, but can be used anywhere.
* [[Bus]]es, which are spaced further apart and allow a player to cover more distance in a single trip.
* The [[London Underground|Underground]], whose stations are spaced even further apart than the bus stops and allow long-distance travel.
* [[Ferry|Ferries]], which only Mr. X can use with a black ticket, allowing him to follow routes along the [[Thames|River Thames]] between [[Greenwich]] and [[Whitehall]].

Each detective begins with a finite mix of taxi, bus, and underground tickets.<ref name=Hasbro-85/> Mr. X starts with the remaining transport tickets; however, detectives must turn their used tickets over to Mr. X, effectively giving that player unlimited travel resources.<ref name=Hasbro-85/>

From any given space, movement is possible along a line matching the mode of transportation (taxi, bus, or underground) to the closest adjacent space for that mode.<ref name=Hasbro-85/> Each space is coloured to indicate the modes of transportation available there: yellow for taxis, green for buses, red for the Underground. For example, a player at space #74 could move as follows:
* Taxi to 58, 73, 75, or 92 (closest taxi stop spaces connected by a solid yellow line)
* Bus to 58 or 94 (closest bus stop spaces connected by a solid green line)
* Underground to 46 (sole closest underground stop space connected by a broken red line)

Mr. X also has a supply of black tickets that are valid for any mode of transport available at their current location.<ref name=Hasbro-85/> These tickets can also be used to move between the ferry stops on the River Thames, joined by black lines; Mr. X is the only one who can travel in this manner.<ref name=Hasbro-85/> In addition, the player assuming the role of Mr. X is given several double-move tokens, which allows them to make two moves in a single turn.<ref name=Hasbro-85/>

A space may be occupied by only one (visible) pawn at a time. If an adjacent space is already occupied, the pawn may not be moved there. However, a player travelling by bus or underground may bypass an occupied space if the closest adjacent stop in that direction is open.<ref name=Hasbro-85/>

Mr. X's movements are documented through a "travel log" with paper inserts, divided into slots that are covered by used tickets. For each move that Mr. X makes, they write down their destination secretly and then cover it with the ticket they have used to reach it, thus providing the detectives with clues as to their whereabouts. The first number written down is not the starting space, but is the first destination using the ticket displayed.<ref name=Hasbro-85/> If a double move is used, Mr. X must log both moves separately, use a transportation ticket for each one, and surrender one of the double move tickets.<ref name=Hasbro-85/> Mr. X moves first on every turn, after which the detectives move in any order.

At five specific times during the game, Mr. X has to reveal their current position. The windows on the travel log for these moves are shaped differently to remind the player to do so.<ref name=Hasbro-85/> Detectives may take this opportunity to refine their search and, if possible, plan ways to encircle them based on where they are and the next few moves they make. Should one of these five moments occur on the first half of a double move, Mr. X makes the first move, places their pawn on the space visited and allows the detectives to see it, then removes it and makes the second move.
