A FEW GOOD QUESTIONS

Curious by nature?

How does the population split game work?

Move a straight line across a real map to divide its estimated population into two equal groups. In Explore, only people inside the outlined map window count. In Countries and States & provinces, only people inside the selected boundary count. After you confirm, you’ll see the percentages on each side. A 50/50 split earns 100 points. Each percentage point away from 50 reduces your score by two points.

Where do the population numbers come from?

We use the European Commission’s Global Human Settlement Layer (GHS-POP R2023A), with residential population estimates for 2020. The grid includes urban and rural areas and is aggregated for a fast browser game. These are modelled estimates. Read about the data and map coverage.

Is there a new puzzle every day?

Yes. The daily challenge has five map windows across different continents in a fixed order, shared by everyone on the same UTC date. It changes at 00:00 UTC. Your daily result and streak are saved in this browser. You can keep playing in Free play whenever you like.

Can I challenge my friends?

Yes. Choose Challenge a friend, enter a nickname and share the invitation. Everyone gets the exact same five maps in the same order, including the same Explore crops. Play at your own pace and compare final scores in the shared standings. Up to 16 players can join, and each challenge closes after 24 hours. Your guesses are saved as you play.
