If played within a conventional game of MC, the traditional way of ending a Boardman's round is by playing a station that is valid both under standard MC and Boardman's conditions: for instance, "West Acton", with the West from West Ham and the Acton from East Acton. If the game is being played as a variant in its own right, the most usual winning move is "Mornington-on-the-Hill", though others have been used on occasion.
