Nucleum: Gibraltar

Your Boats extend your network like rail lines, but shipping lanes are not Railway tiles for Milestones, Contracts, or scoring Technologies. You can transport coal and uranium with your own Boats, not electricity, and you cannot use another player’s Boat; the long-distance lanes to England and Türkiye are not part of anyone’s network (p. 6).

You need a shipping connection to import coal from either source. England’s coal always costs 2 Thaler per coal, with a limit of 2 coal from England per Energize action; Türkiye follows the base-map import rules (p. 8).

No: a Chaining tile can’t be placed as a railway, and you may play no more than one Chaining tile per turn. Fully resolve its action before placing and resolving the non-Chaining tile on top; you also can’t fulfill an additional Contract that turn by placing the Chaining tile (p. 6).

A Special Urban Building can only go on a site that allows its building type, and a Special Urban site can hold only a Special Urban Building. Treat your own as a regular Urban Building when Energizing, but you can’t interact with another player’s Special Urban Building (p. 7).

To fulfill one, you must meet its requirement—including connecting Gibraltar and the specified items in the same network using your own shipping lanes and co-owned completed railways—and follow the regular procedure for a Purple Contract; you can’t take one with the Contract action. The Military Technology reward does not count toward the 8-Technology endgame condition, and the Military Contract offer is not refilled (p. 7).
