Guess the Flag
The classic world flag quiz: we show you a flag, you guess the country. How many of the world's flags can you name?
Guess the flag by region
About this flag quiz
This guess-the-flag quiz covers all 194 UN-member country flags. Each round shows a single flag and four country options — pick the right one and your score climbs over ten flags. It's deliberately simple: no sign-up, nothing saved, just you against the flags of the world.
If the full world flag quiz feels like a lot, narrow it down. Drilling one continent at a time — the flags of Europe, Africa or Asia — is the quickest way to actually learn them, because every flag reinforces a regional pattern instead of competing with the whole map. Start gentle with easy mode, then test yourself on the trickiest flags in hard mode.
