Bordle is a free daily puzzle from Bordr. Every day there is one mystery land border between two countries, and you have six guesses to name it. No account is needed to play.
Each guess is scored against the answer on five clues, so a wrong guess still narrows things down:
Clue data comes from the CIA World Factbook and UN Comtrade. Solve it and you get an emoji grid to share, and a streak that follows you across devices when you sign in.
Bordr itself is a place to log and read first-hand stories about crossing real borders — what the crossing was like, how long it took, what it felt like.
