About Borders
Borders is a free daily geography puzzle. Each day you get one country, and your job is to name all of its land neighbors.
It’s quick to play, gets harder through the week, and works on phones and computers. You don’t need an account or an app store.
Border rules
Whether two countries “border” each other depends on what you count. Borders uses one clear rule: mainland physical land borders only. Overseas regions, territories, and overseas enclaves are excluded.
- Not borders: France–Brazil and France–Suriname (French Guiana), France–Netherlands (Saint Martin), Spain–Morocco (Ceuta and Melilla), Spain–UK (Gibraltar), UK–Cyprus (sovereign base areas), and Canada–Denmark (Greenland and Hans Island).
- No crossings: bridges, tunnels, and sea crossings don’t count, so India and Sri Lanka aren’t neighbors.
- Microstates count: Vatican City, San Marino, Monaco, Andorra, and Liechtenstein are countries.
- Exclaves keep their borders: Russia’s Kaliningrad and Azerbaijan’s Nakhchivan count, so Russia borders Poland and Azerbaijan borders Türkiye.
- Grouped regions: Hong Kong and Macau are part of China, so their internal boundaries don’t count.
- Disputed areas: Kosovo and Western Sahara appear separately, and other disputed boundaries follow the source data.
These are rules for the game, not statements about sovereignty. The answers come from a fixed list of neighbors, not from the map’s shapes.
