In the multiplayer puzzle game Railroad Ink, the goal is to connect as many exits on your board as possible. Each round, a set of dice are rolled in the centre of the table, determining which kind of road and railway routes are available to all players.

Use the 4 special dice of the Eldritch Expansion Pack plus your regular Route dice, and find new ways to score points:

• Ritual (1 die): open new Portals and add mysterious Rituals to make a Madness Network!
• Portal (1 die): open different supernatural Portals to connect distant parts of your network!
• Tentacle (1 die): extend Tentacles along your network as much as you can to obtain bonus points for each space occupied!
• Investigation (1 die): send your Investigator to collect Clues to solve the case and get extra points!

At least one core set of Railroad Ink or Railroad Ink Challenge is required to use this expansion pack.
