Border Guess

Name the country from its outline alone. Each wrong guess tells you how far away it is and which way to look. A daily set of three plus longer practice runs.

How to play

  1. A country outline appears with no name. Type a country in the box, or tap one of the suggestions that match what you typed.
  2. Every wrong guess shows the distance in kilometres, a compass direction and a closeness percentage, so you can home in on the answer.
  3. You get five guesses per country. Use Give up to reveal the answer and move on.
  4. The daily is three countries. Practice runs have three, five or eight, and the timer starts on your first guess.

Tips and strategy

  • Look at coastlines first. A long thin coast or a large island chain narrows the region fast.
  • Use the direction from your first guess to pick a continent, then guess a well known country there to measure the distance.
  • Outlines are drawn to fill the frame, so ignore size. Small countries look as big as large ones.
  • Common short names such as USA, UK, UAE and Ivory Coast are accepted.

FAQ

Where do the outlines come from?
They come from Natural Earth, a public domain map dataset, simplified so they load instantly. Small island nations are left out because they are too tiny to draw.
Does the size of the outline show the real size?
No. Each outline is scaled to fill the square, so a tiny country can look as large as a huge one.
Is the daily the same for everyone?
Yes. The three countries are chosen from the date, so everyone gets the same set each day.
