Flag Quiz
Which country does this flag belong to? 10 questions per round.
About this quiz
Each round shows 10 random flags; pick the matching country from four options. The set covers 120 countries from every continent — from easy ones like Japan and Canada to trickier pairs that look almost identical. Choose a difficulty first: Easy draws from the 50 most recognisable flags, Medium from 100, and All from the full 120. No flag repeats within a round, and your choice is remembered for next time. The flags are drawn as SVG, so they stay sharp on any device.
Reading a flag before you know the country
Flags cluster by region far more than most people notice, and learning the clusters is faster than learning the flags. Red, gold and green in horizontal bands almost always means Africa, borrowed from Ethiopia, the one African state never colonised. A red and white crescent with a star points to a country with Ottoman history. Blue and white crosses belong to the Nordic countries, all five sharing the same off-centre design. The Union Jack in a corner marks a former British territory, from Australia to Fiji.
A red, white and blue horizontal tricolour usually descends from the Dutch flag, the oldest of them, which influenced Russia and through Russia most of the Slavic world. Vertical tricolours generally trace back to France instead.
The pairs that catch everyone out
- Chad and Romania are essentially identical — blue, yellow and red vertical bands, differing only in a slightly darker blue for Chad.
- Indonesia and Monaco are both red over white; Monaco's is slightly squarer.
- Ireland and Ivory Coast use the same three colours in reverse order — green first for Ireland, orange first for Ivory Coast.
- Australia and New Zealand both carry the Union Jack and the Southern Cross; New Zealand has four red stars, Australia six white ones.
- Norway, Iceland and Finland share the Nordic cross; the colour order and the shade of blue are the only way to tell them apart quickly.
Working through the difficulty settings
Easy draws from the fifty most recognisable flags, Medium from a hundred, and All from the full set of a hundred and twenty covering every continent. No flag repeats within a round of ten, so a round genuinely samples the pool rather than asking the same country twice.
If you want the learning to stick, do not simply move up when a level feels easy. Go back to Easy and try to name each flag before the options appear — recognising from four choices is a much weaker form of knowing than producing the answer yourself, and the gap shows up immediately.
Frequently asked questions
How many flags are in the quiz?
120 national flags from every continent — 32 from Europe, 30 from Africa, 29 from Asia, 22 from the Americas and 7 from Oceania. Three difficulty levels let you choose the pool: Easy draws from the 50 most widely recognised flags, Medium from 100, and All uses the full 120. Within a round the same flag never repeats, so every one of the 10 questions is a different country.
How can I memorise flags more easily?
Group flags by shared colours or patterns, link a flag to something about the country, and watch out for look-alikes (like Chad and Romania, or Indonesia and Monaco).
Are the flags accurate?
Yes. Every flag is drawn as a scalable SVG image, so it stays sharp on any screen and displays correctly even on devices that don't render flag emoji.
Which country has a flag that isn't rectangular?
Nepal — its flag is two stacked triangles, the only non-rectangular national flag in the world. Switzerland and Vatican City are the other odd ones out: their flags are square.
What do the colors on flags usually mean?
Color families often signal a shared history: green-yellow-red are the pan-African colors, red-white-black-green the pan-Arab colors, and the off-center Nordic cross links Denmark, Sweden, Norway, Finland and Iceland. Spotting these groups makes flags much easier to memorize.
How many national flags are there in the world?
The UN has 193 member states, plus 2 observer states (Vatican City and Palestine), so about 195 flags is the usual answer — more if you count territories and partially recognized states, each with distinctive flags of their own.
Which national flags are almost identical?
Several famous pairs: Chad and Romania differ only in a barely visible shade of blue; Indonesia and Monaco share the same red-white design with different proportions; the Netherlands and Luxembourg differ mainly in the blue stripe's brightness. Ireland and Côte d'Ivoire are mirror images. These pairs are the ultimate flag-quiz trap.
What is the oldest national flag still in use?
Denmark's Dannebrog — a white Nordic cross on red — is usually credited as the oldest continuously used national flag, with roots going back to the 13th century. Legend says it fell from the sky during a battle in 1219. Its cross design later inspired the flags of all the other Nordic countries.
