Railroad Ink Challenge: Solo Board
A solo puzzle variant that gives a unique board with timed objectives that expire as the game progresses. Players roll dice to draw routes and build a connected network of roads and rails, aiming to meet goal targets before their timers run out. Research lab spaces can be integrated into the network; connecting one grants a reroll ability for dice, providing tactical options to reshape the map. Play focuses on route placement, managing limited turns, and using lab rerolls to optimize connections and score under the solo constraints.

Rules questions
Answered from the rulebook by Ludoya's rules assistant.
When do I gain a Research point?
When you draw a Route with at least one Railway or Highway in its space, fill the leftmost available dot on the Research track to unlock a Research point (p. 1).
How many Research points do I start with?
You start with 3 unlocked Research points (p. 1).
Can I reroll more than one die with a Research point?
Yes. After rolling the dice, spend one unlocked Research point to reroll any number of dice. You may spend multiple points, choosing any number of dice each time (p. 1).
Can I use a Research point again after I’ve spent it?
No. Cross off a Research point after using it; only points that have been unlocked and not crossed off can be spent (p. 1).
Do I use the regular Goal rules when playing solo?
Use the Solo mode rules for Goal cards. The Solo board’s Goal section reminds you of the turn numbers and points for timed Goals (p. 1; the Solo mode rules are on p. 15 of the Lush Green or Shining Yellow rulebook).
