On the Underground: The Underground Challenge – London / Berlin

This mini-expansion adds a solo challenge against the existing Underground lines on the map. The board begins with several lines already built; the player takes four actions per turn (placing Track tokens or taking Branch tiles) and then resolves Passenger movement twice. Passengers visit one or two stations on each movement, removing and replacing matching Destination cards as in standard play. When multiple routes tie, the player must pick the route that awards the Underground the most points; only truly equal routes may be freely chosen. The scenario ends when the player’s Score tile meets or exceeds the Underground’s tile.
