From the Stars and Stripes to the rising sun of Japan, every nation tells its story in a flag. The Flags of the World Quiz tests how many you really know — all 194 UN-member countries, in a fast, modern game you can play on any device.

Play it both ways: see a flag and name the country, or see a country and pick its flag from four. Sharpen up with multiple choice, prove yourself by typing the answer, or race the clock in Speed Run.

Come back each day for the Daily Challenge — ten flags that are the same for everyone, with a shareable results grid so you can see who knows their vexillology best.

How to play

Daily Challenge — ten flags, the same for every player today. Finish to reveal your 🟩🟥 grid and share it.
Flag → Country — name the country a flag belongs to. Easy (multiple choice), Medium (first-letter hint) or Hard (type the name).
Country → Flag — the reverse: you get a country name and pick its flag from four options.
Speed Run — name as many flags as you can before time runs out, building a streak multiplier.

Every mode tracks your streak, score and accuracy, with a local leaderboard for your best runs.

Tips for learning the world’s flags

Group flags by shared design families: the Nordic cross (Scandinavia), the pan-African red-gold-green, the pan-Arab colours, and the red-white-blue tricolours.
Watch the lookalikes: Chad vs. Romania, Indonesia vs. Monaco, Ireland vs. Côte d’Ivoire, the Netherlands vs. Luxembourg — these decide close games.
Use emblems and symbols as anchors: a maple leaf, a cedar, a dragon, a star-and-crescent each point to one country.
Learn a continent at a time — our Learn-mode flag library lets you browse and search every flag with its country facts.

How the daily challenge works

The daily set is generated from the calendar date with a seeded shuffle, so everyone in the world sees the same ten flags on the same day — no account, no tracking. Your result is encoded as a grid of green (correct) and red (wrong) squares, ready to copy or share. A new set drops every day.

Data & method

Country facts come from the open mledoze/countries dataset (ODbL), filtered to the 194 UN members. Flag images are public domain, bundled as SVGs via flagcdn and served with the app so they render identically on every device — unlike flag emoji, which don’t display on Windows. Everything is bundled, so the quiz works offline.

Frequently asked questions

How many flags are in the quiz?

All 194 UN-member countries are included. You will be quizzed on every sovereign national flag, from the most familiar to the trickiest lookalikes.

How does the daily challenge work?

Each day there is a fixed set of 10 flags that is identical for every player worldwide, generated from the date itself with no server needed. Finish it to reveal a shareable grid of green and red squares to compare with friends.

Can I play both flag-to-country and country-to-flag?

Yes. In Flag → Country you see a flag and name the nation; in Country → Flag you see a country name and pick its flag from four options. There is also a timed Speed Run and a searchable flag library in Learn mode.

Why does the quiz use flag images instead of emoji?

Flag emoji do not display on Windows or many desktop browsers — they fall back to two-letter codes. To make sure every flag looks right for everyone, we use real public-domain flag images bundled into the app.

Does it work on mobile?

Yes. The quiz is mobile-first and runs in any modern browser on phone, tablet or desktop, with no app or sign-up required.

Where do the flags and data come from?

Country facts come from the open mledoze/countries dataset (ODbL) and the flag images are public domain (via flagcdn). Everything is bundled into the app, so it loads instantly and works offline.
