Reborder
The world without its lines. Reborder shows two neighbouring countries as one blank shape, and you draw where the border should be.
Opens the real game on reborder.app. Free, in a new tab.
How Reborder works
See the shape. Two neighbouring countries appear with the border removed.
Draw a line. Draw where you think they meet. Your line may start and end outside the map. Daily rounds give you 60 seconds.
Check your score. See how close your line was to the real border.
Border types
- River: Many borders in Europe and South America
- Mountain ridge: Alps, Andes, Himalayas
- Straight line: Deserts and former colonies
Anchor the ends
Start by placing the two ends of the border where it meets the coast or a third country. Those points are easier to remember. Then join them with the kind of line the region usually has, whether a winding river or a straight survey line.
Common Reborder questions
Is Reborder an app or a website?
A website. It runs in the browser at reborder.app, on a phone or a computer.
Is there a Reborder unlimited mode?
Practice mode is the closest thing. It has no timer and sits apart from the daily challenge.
Where does the map data come from?
Country shapes come from a Natural Earth based world atlas, and US state shapes from Census Bureau data.
Is there a multiplayer mode?
Yes. Live 1v1 and Leagues let you play against others.
Are scores saved?
Daily progress stays in your browser, and signed in players also keep scores and league data on their account.
Reborder strategy
- Look for rivers and mountain ranges in your mind. Many borders follow them.
- Straight lines are common in some regions, especially in deserts.
- Practice mode has no timer, so learn tricky pairs there.
- Your line can start outside the map, so sweep right through the shape instead of stopping short at the edge.
