Ticket to Ride Map Collection: Volume 6 â€“ France & Old West includes a double-sided game board that features France on one side and the western half of the United States on the other.
In the Old West half of the expansion, 2-6 players start the game by choosing (in reverse player order) a starting location for one of their three city pieces. The first route that a player claims must have this city as one of the route’s two endpoints, and each subsequent route claimed must connect to that player’s existing network.
After claiming a route, a player can place one of their remaining cities on either end of that route by discarding a matching pair of train cards. Only one city marker can be in each city. Whenever a player builds a route that connects to a city owned by another player, the owner of the city claims the points for the route, not the player placing the trains. If both endpoints of the route have cities, then the owner of each city scores these points. Whoever completes the most tickets in this expansion scores 15 bonus points.
As a variant, you can play Old West with Alvin the Alien. No player can start the game in Roswell, and the first player who builds a route into Roswell scores 10 points, then places the Alvin marker in any city that they control. The next player to connect to this city scores 10 points, then moves Alvin as before. Whoever controls Alvin at the end of the game scores 10 bonus points.
