Border Patrol

How to play

1. Select one country from the choices. Land borders involving overseas territories and enclaves count; a sea crossing alone does not.
2. Each question accepts one answer. A correct answer adds one point and an incorrect answer adds none; review the explanation for the border involved.
3. Select Next question after reviewing each answer. Answer every question shown to complete the challenge, then review your answers.

Head-to-head rules

Answer the most questions correctly. Both players get the same questions and 2 minutes for the entire quiz, including answer reviews. Wrong or unanswered questions earn no points. If scores tie, the faster completed run wins; a completed run beats an unfinished run. Completed times within 0.1 seconds draw. If both tied runs are unfinished, the match is a draw.

Your moves and answers stay private. Leaving through the game controls forfeits the match; closing the page does not pause its clock.

Real-player matches update this game's own Elo rating. Daily and practice results keep their separate progress and never change Elo.
