- Just outside the ten: Greece, 13,676 km.
- After the game every button shows its place in the order.

Note on the data. Land borders, land boundary lengths, coastlines and highest points are those of the CIA World Factbook in its last (2025) edition, read on 3 October 2026 from the archived copies of the agency's own field pages, parsed by script and checked to be symmetric. A border through a dependency (French Guiana, Gibraltar, Greenland, Ceuta and Melilla) or one that depends on a disputed status (Kosovo, Palestine, Western Sahara, the Golan Heights) is on a doubtful list and is never asked. The order was computed from the Coastline field for Ribbia's 197 countries.
