Railroad Ink Challenge Electricity Dice Expansion

In the multiplayer puzzle game Railroad Ink™, your goal is to connect as many exits on your board as possible. Each round, a set of dice are rolled in the middle of the table, determining which kind of road and railway routes are available to all players. Use the 4 special dice of the Electricity Expansion Pack in addition to your regular Route dice, and find new ways to score points:

Street Lamp (2 dice): build Street Lamps and power them with Generators to light your board and score a lot of points!
Power Grid (2 dice): connect your Exits to the central Accumulator and charge it with electricity to multiply your bonus points!

Note: at least one core set of Railroad Ink™ or Railroad Ink Challenge™ is required to use this expansion pack.
