A daily geography game, one straight line at a time
Halve is a free geography game that changes every day. You get one country and a straight edge: cut it into two equal halves, three times. Your eye for maps does the rest.
How to play Halve
Every day brings one country, the same for every player, and three rounds on it.
Draw one straight line across the country, adjust its two handles, then cut. One cut per round, and it's final.
Round 1 splits the country's area. Round 2 splits its people. Round 3 splits an unusual layer, announced at the start of the round and shown only after your cut.
Each round scores up to 100 points: the closer your split is to 50/50, the more you score. A cut within half a point of 50/50 is perfect.
A new country arrives at 01:00, Paris time.
Questions
Is Halve free?
Yes. Halve is free and you can play without an account. A free Letsdle account is optional: it keeps your stats and streak on every device.
Where do the maps and the population come from?
Borders come from Natural Earth (public domain). Population comes from GHSL 2025, by the European Commission's Joint Research Centre, and land cover from ESA WorldCover. Each is grouped into weighted points, so a split is measured to a fraction of a point.
How are disputed borders handled?
With one neutral rule everywhere: borders follow Natural Earth, and disputed areas are left out of every country that claims them.
What is the unusual round?
Round 3 cuts the same country by something unexpected: its forests, its deserts, its water, or a hand-picked theme for some countries. You only see where it lies after your cut.
Can I share my result without spoiling the country?
Yes. The share text and image show your three scores and the edition number, never the country of the day.
