Railroad Ink Challenge: Lush Green Edition

Yes — after the roll all players draw simultaneously and you must draw all 4 Routes shown on the dice each round if it is possible to do so (you may rotate or reverse the patterns). (Rulebook, p.4–5)

If a Route cannot be connected to an Exit or an existing Route you simply cannot draw it that round (you’re allowed to skip drawing any die face you can’t legally place); incomplete/open ends are only penalized at the end of the game as Errors (−1 each). (Rulebook, p.5; end‑game Errors, p.10)

No — you may not draw Routes that directly connect Railways to Highways; use a Station to connect them, while an Overpass lets them cross without connecting. (Rulebook, p.4, p.5)

You may draw one Special Route per round and at most three Special Routes per game (mark each used Special Route off your board); Special Buildings (Factory, Village, University) trigger their effects immediately when activated, those effects can chain (e.g., a Factory duplicates a die, a University can grant a free Special Route when its track is completed). (Rulebook, p.6–7)

Stations do not interrupt longest Highway or Railway paths and can be used to connect Railway and Highway networks; for the Trail expansion, Trails auto‑connect to Stations at a corner and Station networks score half the normal Network Value. (Rulebook, p.11–12; Trail dice rules, p.22)
