Three countries, one meeting point, every border between them wiped. Tap where all three meet: the closer, the better. Each day's puzzle is a spot where three of the world's countries meet.
A daily puzzle about the points where three countries meet. The three are drawn as one shape with every border between them wiped, and you drop a pin where they come together. Tripoints often sit on a river confluence or a mountain summit, and a few are in a lake.
How it works
1The three places are drawn as one shape, with every border between them wiped off.
2Tap where all three meet. Tap again to move your pin, then submit.
3The closer your pin, the higher your score, out of 1000. Misses are judged against the size of the countries.
Tips
Follow the outer edge. Two of the borders usually run in from the edge of the shape, and the tripoint is where they meet.
Rivers and mountains help. Tripoints often sit on a river confluence or a summit.
Zoom in before you submit. At world scale, a tap that looks right can still be tens of kilometres off.
Questions
How is it scored?
Out of 1000, by distance from the true tripoint. How far counts as a miss depends on the size of the countries: 50 km is a lot for Switzerland, Germany and France, but not for Kazakhstan, Kyrgyzstan and Uzbekistan.
What if three countries meet twice?
Some trios meet at two points. Either counts, and you're scored against the closer one.
Which trios come up?
Any three countries that meet on land, weighted toward familiar ones, and none repeats within six weeks.
When is there a new daily?
Every day at midnight where you are. Everyone gets the same puzzle on the same date, and practice rounds are random.
Where three countries meet
Some tripoints are marked with a monument you can walk round, like the one at Vaalserberg where Belgium, Germany and the Netherlands meet. Others sit in water: the cairn where Finland, Norway and Sweden meet stands in a lake, and the Golden Triangle, where Laos, Myanmar and Thailand meet, is the confluence of the Ruak and Mekong rivers.
Countries with many neighbours have many tripoints, and every one is a place where two borders come in from the outer edge and join. Learn's map oddities cover several of the stranger ones.
