Railroad Ink: Underground Expansion Pack

Adds a set of four dice that create separate underground networks of subway routes and water pipes, offering alternate scoring and connection patterns. Can be played standalone to replace the normal route dice and build only underground networks, or used as an expansion alongside the core game to run two parallel boards per player: one for Surface routes (using the original dice) and one for Underground routes (using the expansion dice). Players roll dice each round and draw corresponding tiles on their boards to connect exits, optimizing layouts to score by linking routes and completing network features. A core set of the base game is required for Expansion mode.
