Ticket to Ride: Rails & Sails

No — routes with rectangular spaces are train routes and must be claimed with train pieces and Train cards; routes with oval spaces are ship routes and must be claimed with ship pieces and Ship cards, and the cards must match the route’s color/count (gray routes accept any one color). (page 4)

No — taking a face‑up Wild card is the only Travel card you may take that turn; a Wild flipped as a replacement or left faceup cannot be taken as your second card, though drawing a Wild from the top of a deck in a blind draw still counts as a single card and you may draw a second card that turn. (page 4)

Double‑Ship cards can place up to two ships per card, so you may combine Double‑Ship and Single‑Ship cards to match the route’s number of spaces (for example, a five‑space ship route can be claimed with two Double‑Ship cards and one Single‑Ship card, or three Double‑Ship cards but you still place only five ships). (page 4)

A Pair space requires two Train cards of the same color instead of one for that space; you may use any color and different spaces need not use the same color, and Wild cards may be used as part of a pair. (page 5)

To build a harbor you must play two Train cards AND two Ship cards, all the same color and bearing the harbor symbol (Wilds may substitute); built harbors score 20/30/40 points depending on completed tickets into them, and each harbor you do not build costs you 4 points at game end. (page 6)

When any player’s supply of plastic pieces contains six pieces or fewer, every player (including that player) gets two more turns, after which the game ends and final scoring takes place. (page 7)
