How many of the 50 US state capitals can you name? Most people breeze through California and New York but freeze on Pierre, Montpelier, or Frankfort. This free US state capitals quiz turns that blank spot into a game: an interactive map of the United States, instant feedback, and four ways to test yourself — plus a daily challenge you can share with friends.

Pick your mode and difficulty, then race the clock or take your time.

Every question builds a streak multiplier, and a clean recap at the end shows exactly which capitals to review.

It runs entirely in your browser, works great on phones, and saves your best scores locally — no sign-up, no app to install. Come back each day for the Daily Challenge: six capitals, the same for everyone, with a shareable emoji-grid result and a day streak to keep going.

How to play

Name the Capital — a state lights up on the map and you name its capital. Choose Easy (multiple choice), Medium (first-letter hint), or Hard (type it in).
Capital → State — the reverse: given a capital city, name the state it belongs to.
Find the State — we name a capital and you click the correct state on the US map.
Speed Round — type as many capitals as you can before the clock catches up to you.
Daily Challenge — six capitals chosen by the date, identical for every player that day. Finish it for a shareable 🟩🟥 result grid and build a daily streak.

Prefer to study first? Switch on Learn Mode and tap any state to see its capital, region, population, area, statehood date, and a quick fact about the capital city.

How many US state capitals are there?

There are 50 state capitals — one for each US state. Washington, D.C. is the nation’s capital but it is a federal district, not a state, so it has no state capital of its own; this quiz covers the 50 states only.

The classic trap is assuming the capital is the biggest or most famous city. In most states it isn’t. New York’s capital is Albany, not New York City; California’s is Sacramento, not Los Angeles; Illinois picks Springfield over Chicago; and Texas chooses Austin over Houston or Dallas. Knowing which capitals are not the largest city is half the battle.

Tips for memorizing the 50 state capitals

Group by region. Learn the nine Northeast capitals first, then the Midwest, South, and West. Smaller batches stick better than all 50 at once.
Anchor the tricky ones. Tie a hook to each hard capital — Pierre, South Dakota (“peer” near the middle of the map); Montpelier, Vermont (the smallest capital); Frankfort, Kentucky (not Louisville or Lexington).
Watch the look-alikes. Charleston is the capital of West Virginia — Charleston, South Carolina is a different city and a common mix-up.
Use the map. Pairing each capital with its location on the US map builds spatial memory that pure word lists can’t.
Repeat daily. A short daily round beats one long cram session — that’s what the Daily Challenge is for.

Where the data comes from

The map uses the public-domain us-atlas state boundaries (US Census Bureau / Natural Earth). State capitals and the supporting facts — region, population, area, and statehood dates — are drawn from US Census and public reference data. Everything is bundled into the quiz ahead of time, so it loads fast and works without any live connection. The facts are static and rarely change.

Frequently asked questions

How many US state capitals are there?

Fifty — one capital for each of the 50 states. Washington, D.C. is a federal district, not a state, so it is not included.

Which state capitals are not the largest city in their state?

Most of them. Well-known examples include Albany (New York), Sacramento (California), Springfield (Illinois), Austin (Texas), Tallahassee (Florida), Annapolis (Maryland), Harrisburg (Pennsylvania), and Salem (Oregon). Only a handful of capitals — like Phoenix, Indianapolis, and Honolulu — are also the biggest city.

Is Washington a state capital?

No. Washington, D.C. is the capital of the United States, but it is a federal district rather than a state. The state of Washington has its own capital, Olympia.

Can I play a daily challenge?

Yes. The Daily Challenge gives every player the same six capitals each day. Finish it to get a shareable emoji-grid result and to extend your day streak.

Does it work on mobile?

Yes. The quiz is mobile-first — the map, buttons, and typed answers are all sized for touch, and your scores save on the device you play on.

Where does the data come from?

Map boundaries come from the public-domain us-atlas dataset (US Census / Natural Earth). State capitals and facts come from US Census and public reference sources, bundled into the app so nothing is fetched at runtime.
