Quick answer

To play Railroad Ink Challenge with the Sky Expansion, add the Sky expansion dice to the pool and follow the new route-drawing rules for aerial connections. Use the steps below to integrate it smoothly and avoid common scoring mistakes.

What the Sky Expansion adds to your game

The Sky Expansion introduces new dice that let you draw elevated routes, bridging over existing lines and connecting exits in fresh ways. This opens up more creative path-building but also adds a layer of planning: you must decide when to go airborne versus staying grounded.

Because the expansion is designed for the Railroad Ink Challenge series, it works with any Challenge base game. You do not need to own other expansions to use it, though mixing multiple expansions can increase complexity and playtime.

When to use the Sky Expansion (and when to skip it)

The Sky Expansion shines when you want more flexibility and replayability. It is ideal for players who have mastered the base game and are looking for new strategic decisions. However, if you are teaching the game to newcomers, consider playing without it first, as the extra options can overwhelm first-timers.

Also, note that the expansion does not include solo-specific rules; it is played the same way in solo as in multiplayer. If you primarily play solo, you can still enjoy the added variety.

Step-by-step: playing with the Sky Expansion

Set up the expansion dice: Add the Sky expansion dice to the dice pool for each round. The exact number of dice depends on player count; follow the expansion's rulebook for the correct mix. Common mistake: forgetting to remove the base game dice that the expansion replaces. Check the rulebook's dice setup chart before your first game.
Draw aerial routes: When you roll a Sky die, you may draw an elevated route on your board. These routes can cross over existing lines without connecting to them, but they must still connect to exits or other Sky routes. Common mistake: treating aerial routes as normal roads that block ground-level connections. Remember that aerial routes do not interact with ground-level routes unless specified.
Score aerial connections: At the end of the game, score Sky routes as instructed in the expansion rules. Typically, they count toward connecting exits but may have different scoring conditions. Common mistake: assuming they score exactly like regular routes; always double-check the expansion's scoring section. Review the scoring examples in the rulebook to avoid under- or over-counting.
Adapt your strategy: Use Sky routes to reach otherwise inaccessible exits or to bypass crowded areas. Plan ahead: once you commit to an aerial path, it may limit future ground-level options. Common mistake: overusing Sky routes and neglecting ground-level connections that are easier to complete. Balance aerial and ground routes to maximize exit connections.
