In the multiplayer puzzle game Railroad Ink, your goal is to connect as many exits as possible on your board.
Each turn, a set of dice is rolled in the middle of the table, determining the type of roads and railroads available to all players.
The Underground expansion pack contains 4 dice that you can use in two ways.
In Standalone mode, you use them instead of the normal road dice to build underground networks of subway lines and water pipes and score points in a whole new way.
In Expansion mode, you use them along with the normal route dice, but without mixing them up! You need two boards for each player, one for the surface and one for the basement. The basic route dice are used on the Surface board (per the normal rules), while the route dice (and rules) are used on the Underground board!
The basic Railroad Ink or Railroad Ink Challenge game is required to use this expansion pack
