In the multiplayer puzzle game Railroad Ink™, your goal is to connect as many exits on your board as possible. Each round, a set of dice are rolled in the middle of the table, determining which kind of road and railway routes are available to all players. Use the 4 special dice of the Sky Expansion Pack in addition to your regular Route dice, and find new ways to score points:

Weather (2 dice): control clouds, rain, and snow and prevent weather fronts from colliding to score bonus points!
Airline (2 dice): use air routes and airports to extend your networks up to the sky!

Note: at least one core set of Railroad Ink™ or Railroad Ink Challenge™ is required to use this expansion pack.
