About Statedoku
Welcome to Statedoku — a free daily puzzle for anyone who likes US geography or wants to learn it. One grid a day, same one for everyone in the world. Solve it in five minutes, share your emoji grid, come back tomorrow.
The puzzle
Fill a 3×3 grid with US states. Each row and column has a constraint — "borders Mexico", "named after a king", "no state income tax". Every state must satisfy both its row and column. You get 3 mistakes. That's it.
Why we made it
Wordle proved that the right small ritual can teach you something every day without feeling like school. We wanted the same thing for American geography. After a month of Statedoku you'll know the 50 states cold — and a lot of weird trivia about them.
What makes it different
- Every grid has exactly one solution. No guessing.
- ~100 different constraints rotate — regions, borders, history, name origin, sports, mountains, belts. No two days feel the same.
- Mobile-first. Tap a cell, type three letters, pick. Built for thumbs.
- Three languages — English, French, Spanish.
- No accounts required. Play instantly. Your progress saves locally on your device.

Statedoku is a small project, built out of love for daily puzzles and US geography. If you spot a bug, find a constraint that feels unfair, have an idea for a new category, or want to help with translations — please write. We read every message and most good ideas end up shipped.
