In Railroad Ink Challenge, you have 7 rounds to make as many points as possible. Roll the dice and draw the routes to connect the 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! Play solo to improve your best score, or challenge players from all over the world!


Each round you will have to roll the dice and use the available routes to build your transportation network and connect as many exits as possible. Expand your network to collect points. You’ll also score bonus points for your longest highway and railway, for building into the central spaces of your map, and for completing optional, time-dependent goals before they expire.
You can also connect special structures to your network to trigger their special effects, such as duplicating routes, unlocking powerful special routes, and more. But beware: Try to not leave any open connections, as each one will cost you points at the end of the game.


Forest and Desert expansions add special dice and rules to create even more intricate landscapes for your highways and railways.


Play solo with random objectives and join the online rankings or challenge players from all over the world with custom game configurations! The online leaderboards (Daily, Monthly, and All-Time) are completely cross-platform!

• The wonderful art of the roll and write game by Marta Tranquilli, fleshed out and digitally enhanced

Amazing - But where is the lava & meteor die?

My cousin bought the physical game at a game store and brought it on vacation. The graphics are beautiful, it was simple to learn and having a different game every time you play made this game addicting. We were glued to it for our entire weekend getaway - literally played it probably 50 times.

An offhanded comment led to a search in the App Store for an app version of the game and low and behold we found it! This app adds additional elements not found in the base physical game which is awesome. But it appears that the app doesn’t have the lava & meteor expansion dice?? I see the desert & rainforest expansion options are coming soon but what about the others? Any plan to incorporate them into the app? The meteor/lava dice were one of our favorite part of the physical game!!

Been thinking about the physical version

I had been thinking about buying the physical version of the game but had never pulled the trigger. So when the App came out, I thought I could give it a try before buying the board version. The App is solid and I love the asynchronous gameplay. I can play with the wife and kids and we can all play at our own pace with no downtime. The game itself is a nice little puzzle as you try to hit goals and leave yourself many options early then rush to close off open ends in the later part of the game. I’m not terribly good yet but am having a blast.

Two complaints: the tutorial game should not give you achievements. I want high scores to come from my own games. Secondly, the motivations are wonky and I have to turn them off to get the red notification number to disappear. Hope both things are fixed, but neither are enough to deduct a star.

Decent implementation but hard to see rules mid game

It would be extremely useful to see the expansion scoring rules as part of the drop-down general scoring information. I couldn’t find a quick reference. In fact I didn’t manage to find it at all and had to use an external source. If the info is there it could be made more easily available; if it’s not there then it needs to be added.
