CoordGuessr
Origin story (skip if you don't care about biologists)
I'm a biologist. I spend a non-trivial amount of time staring at specimen data: collector, date, locality, coordinates... And somewhere between the third row of tubes filled with ants and the fourth hour of the afternoon, I started playing a game: where on Earth is this coordinate, exactly?
No map. No hints. Just a latitude/longitude pair and mild overconfidence.
CoordGuessr is that game. With a timer, a leaderboard, a map, and none of the ants.
What is this
You're shown a pair of GPS coordinates for a location on land. You click where you think it is on the map. The closer you are and the faster you guess, the more points you score.
It may not make you a better person, but it might make you unexpectedly upset about the coordinates of Papua New Guinea.
Features
- ⚡ Fast mode · 3 rounds: for the space between two meetings that should have been emails
- 🕐 Full mode · 10 rounds: for when you've run out of excuses
- 🌍 6 regions: World, Europe, Americas, Africa, Asia, Oceania

- 🗺️ 3 map styles: Standard, Satellite, Topo (for the concerning minority)
- 🏆 Global leaderboard: real people, real scores, real geography embarrassment
Who is this for
People who think latitude and longitude are a personality trait. Field biologists. Geographers at parties. Anyone who has opened Google Maps for fun. Conference attendees killing time between talks. Your friend who always says "I have a great sense of direction."
Technical notes
Coordinates are generated on land using a simplified Natural Earth polygon. Antarctica is included. It is, in fact, land.
The code was written with significant help from Claude by Anthropic, which is either a disclosure or a confession, depending on your views on AI-assisted coding.
Free. No account. No ads. Just coordinates and the quiet shame of clicking on Kazakhstan when it was Portugal.
