Each turn the players draw one or more cards representing cities, then play one or more cards, forming or extending a route through successive cities along a sequence of roads. The route may be extended at either end but cannot include the same city twice. After reaching a certain length, a route may be closed and scored. The player then puts markers on some of the cities on the route that he or she has not marked already — either choosing one city in each province traversed by the route, or choosing one province and marking all of its cities that are on the route.
