Know the Flag: Country Quiz

Four modes: flags, countries, capitals and currencies. Live duels, private rooms, a map and globe to explore, 15 languages. Ad-free; all but the duels works offline.

A calm, ad-free game for actually learning the world's flags. 240 flags, countries and capitals in your pocket.

PLAY — FOUR MODES • Flags: read a country name, pick its flag out of four. • Countries: look at a flag, pick the country out of four. • Capitals: see a country, pick its capital. • Currencies: which country uses which money? • Every mode has its own 12 levels, 20 questions each, 3 stars to earn. Levels open with the world's best-known flags and get steadily harder. • The wrong answers are not random. Türkiye comes with Tunisia and Azerbaijan; Sweden comes with Norway and Finland. Choices are drawn from flag families and geographic neighbours — so you have to actually know it.

DUEL • The same 10 questions, at the same time, against a real opponent. Speed scores as well as accuracy. • The server sets the questions and keeps the score, so both players see the same clock. • Private rooms: hand a friend a six-digit code and play each other. Private matches never touch the leaderboard. • Daily, weekly and all-time leaderboards. Single-player runs are ranked on their own separate board.

EXPLORE • A world map you can pan and zoom, and a globe you can spin. • Tap any country for its flag, capital, population, area and currency.

LEARN • Every flag in one list. Tap a card to flip it for the country and capital. • Filter by continent or search. • The game quietly collects the flags you get wrong most often.

A GAME THAT LEAVES YOU ALONE • No ads. No in-app purchases. No subscriptions. • No tracking: no ad networks, no analytics tools, no tracking code at all. • No sign-up required. Choose a display name and an avatar without creating an account. • Levels, Learn and Explore work with no connection. Only the duels and the leaderboards need the internet. • 15 languages: English, Turkish, Spanish, German, French, Portuguese, Italian, Russian, Bulgarian, Ukrainian, Japanese, Korean, Hindi, Polish and Arabic. Country names, capitals and currencies are translated too, and the whole interface is mirrored right-to-left in Arabic.
