The official adaptation of Railroad Ink Challenge, the critically acclaimed roll and write game by Hjalmar Hach & Lorenzo Silva, is here. Play against players from all over the world Online or locally with your friends in Local Pass & Play mode!

Railroad Ink Challenge™ is a quick playing game about building connections. Each round you roll the dice and draw the routes to connect the exits around your board. Your goal is to expand your network with railways, highways and stations to collect points, but you will be penalised for any open connections, so you’ll need to plan carefully!

Connect special structures to your network to trigger special effects: duplicate a route with Factories, gain bonus points by building Stations next to Villages, and unlock extra special routes with Universities. Each game also features a different set of optional, time-limited in-game goals. Try to complete them before they expire to score even more points!

Create a game and start playing right away! You can send invites to your friends: players joining your same game later will play with the same exact goals and round-per-round dice that you dealt with, creating a fully asynchronous challenge! Who will get the best score?
