Flag Quiz: Can You Name These Country Flags?

This flag quiz shows you national flags from all 193 UN member countries and asks you to name them. Play multiple choice for a casual round or type-in for the real test. Each answer gets instant feedback, your misses queue up for replay, and your score comes with a medal at the end.

What to expect

The quiz mixes easy, medium, and cruel. You’ll breeze through Japan and Canada, slow down at Central Asia, and come to a full stop somewhere in the Pacific. That’s by design: a flag quiz made only of famous flags teaches nothing, and one made only of obscure ones just hurts.

A few landmarks you’ll meet along the way. Nepal’s flag is the world’s only non-rectangular national flag, two stacked pennants instead of a rectangle. Denmark flies the oldest continuously used national flag on Earth. And at some point you’ll face either Chad or Romania and realize you cannot tell which one it is, because their tricolors differ by roughly one shade of blue. Everyone hits that wall. It’s a rite of passage.

Turning guesses into knowledge

Colors carry history, and reading them is the shortcut. Green-yellow-red combinations point to Africa, borrowed from Ethiopia’s flag after it fought off colonization. Red, white, and blue horizontal bands suggest the Slavic world. Crescents lean Islamic heritage, the Southern Cross constellation means the southern hemisphere, and a Union Jack in the corner is a colonial-era receipt.

So when a mystery flag appears, don’t scan your whole memory. Read the flag first: colors, symbols, layout. That narrows 193 candidates to a handful before you’ve consciously thought about it. Players who learn this jump from 60% to 85% in about a week. The last 15% is memorizing the genuinely arbitrary ones, and there’s no trick for those. Just reps.

When you’re warmed up, the flags of the world quiz runs the complete set, continent quizzes like the Europe flag quiz let you specialize, and the hard flag quiz exists for people who think they’re done improving.
