How well do you really know the world map? The World Capitals Quiz tests your geography across all 194 countries — name the capital of any nation, find a country on an interactive world map, and identify countries from their flags. It runs right here in your browser, free, with no sign-up.
Choose from five game modes and three difficulty levels, from gentle multiple-choice to type-it-yourself hard mode. Build a streak to multiply your score, race the clock in Speed Round, and review the countries you missed at the end. A local leaderboard remembers your best runs.
It is the world-spanning companion to our US Geography Quiz — same fast, modern engine, now covering every continent. Scroll down for tips on memorizing world capitals and answers to common questions.

How to play
- Pick a game mode. Capital Cities (match a country to its capital), Locate the Country (click it on the map), Name the Country (identify the highlighted nation), Guess the Flag, or Speed Round.
- Choose a difficulty. Easy gives you multiple-choice options, Medium shows a first-letter hint, and Hard makes you type the full answer.
- Answer the questions. Each correct answer scores points; answer quickly and chain correct answers for a streak multiplier.
- Review your results. See your score, time, and accuracy, then study the list of countries to review before playing again.
How many countries and capitals are there?
This quiz uses 194 countries — the full list of United Nations member states — each paired with its official capital. You will occasionally see the number given as 195 (adding the Holy See / Vatican City) or higher when observer states and disputed territories are included, but 194 is the standard count for a “countries of the world” quiz.
Tips for memorizing world capitals
- Go region by region. Learn Europe, then Africa, then Asia, and so on — grouping capitals geographically is far easier than memorizing a flat list of 194.
- Watch for the “trick” capitals. The capital is not always the biggest city: Canberra (not Sydney), Ankara (not Istanbul), Brasília (not Rio), Bern (not Zurich), Ottawa (not Toronto).
- Use the map. Linking a capital to its country’s shape and position locks it into memory far better than the name alone — that is what Locate and Name modes train.
- Learn the flags too. Flags are a fast, visual hook for the country — and the Guess the Flag mode doubles as flag practice.
- Review your misses. After each round, focus on the “countries to review” list rather than replaying ones you already know.
Where the data comes from
Country and capital facts come from the open mledoze/countries dataset (ODbL licence), and the interactive world map is built from Natural Earth geometry via the world-atlas TopoJSON (public domain). Everything is bundled into the quiz, so it loads instantly and keeps working even on a flaky connection.
Frequently asked questions
How many countries and capitals are there?
The quiz covers 194 sovereign countries — every member state of the United Nations — each with its capital city. That is the figure most geographers use when counting “countries and capitals,” though you will sometimes see 195 (adding the Vatican / Holy See) or higher counts that include observer states and disputed territories.
What is the hardest capital to guess?
The capitals people miss most are the ones that are not the largest or best-known city in the country: Australia (Canberra, not Sydney), Turkey (Ankara, not Istanbul), Brazil (Brasília, not Rio or São Paulo), Switzerland (Bern, not Zurich), and Kazakhstan (Astana). Small island and Central Asian states also trip up most players.
Are these all UN-recognized capitals?
Yes. The country list is limited to UN member states, and each capital is the officially designated seat of government. A few countries have more than one capital (for example South Africa); the quiz uses the primary capital from the source dataset.
Does the quiz work on mobile?
Yes. It is built mobile-first — the world map, answer buttons, and flag cards all scale to a phone screen, and every tap target is finger-sized. Your scores are saved on your own device.
Where does the data come from?
Country and capital facts come from the open mledoze/countries dataset (ODbL licence) and the world map is built from Natural Earth via the world-atlas TopoJSON (public domain). The data is bundled into the quiz, so it loads instantly and works without any third-party connection.
