Once you feel confident enough with the ins and outs of Railroad Ink, you can spice things up by using 1 of the 2 optional Expansions included in this box.
If you play with an expansion , you must roll the respective Expansion dice along with the 4 Route dice at the beginning of each round. In addition, the Expansion may change the number of rounds you must play and give you new ways to score points.
During the game, follow the same rules as the regular game with a few changes, as described below.
At the end of the game, when you add up your score, remember to count the points you earned from the Expansion you're using, and mark them in the designated space of your scoring table.
Rivers are a third kind of Route. Sort of. They can't be used to connect Exits, but they can be connected to each other to create a River. Rivers can't be crossed by Highways or Railways, unless a Bridge face on a River die allows you to do so.
The additional goal is to make the Longest River possible. When playing with the River Expansion , apply these changes to the regular game rules:
The game only lasts 6 rounds.
When you draw Routes, you do not have to draw any of the River dice if you don't want to (you still have to use all 4 Route dice).
The Rivers you draw don't have to be connected to preexisting Routes and/or other Rivers.
You can't connect River Routes with other kinds of Routes (nor Exits ).
When checking for Errors, each end of a River that does not connect to another River or the outer edge of the Board counts as an Error.
At the end of the game, choose 1 of your Rivers. You gain 1 point for each space the River runs through. If both ends of the River are connected to the outer edge of the board, you get 3 additional points.
Example: Diana created 2 River Routes. The longest would be worth 7 points, but its ends are not connected to the edges of the Board. Instead, the shortest one is worth 8 points: 5 for its length plus 3 extra points for having both ends connected to the edges of the Board, so she chooses to score points for that River.
Lakes have two advantages. First of all, they allow you to create bigger Networks by connecting your Routes to a Lake with the Pier faces on the Lake dice.
You also score additional points for the Smallest Lake on your Board. When playing with the Lake expansion , apply these changes to the regular game rules:
The game only lasts for 6 rounds.
When you draw Routes, you do not have to draw any of the Lake dice, if you don't want to (you still have to use all 4 Route dice).
The Lakes you draw don't need to be connected to pre-existing Routes and/or other Lakes.
If a space has 3 sides adjacent to the open sides of Lakes, it must be completely filled with water immediately.
Open Lake sides do not count as Errors at the end of the game.
Networks connected to the same Lake (by Piers) are also connected to each other.
At the end of the game, you get 1 point for each space occupied by your Smallest Lake.
