This expansion pack is compatible with any game in the Railroad Ink series. The Archipelago Board Expansion comes with four boards and a brand new twist on the classic Railroad Ink gameplay: Build your transportation network spanning across multiple islands but beware: you can only draw your dice on one island at a time! These boards also feature a new Special Building, the Warehouse, which allows you to store routes and save them for later use.Railroad Ink games are quick-playing roll-and-write games where you roll dice and draw routes to connect exits around your board. Expand your network with railways, highways, and stations to collect points, but you will be penalized for any open connections, so plan carefully!
