    World flags quiz

    Name the country from its flag, for all 196 countries of the world. Wrong options come from the same region and, where one exists, from a flag that is known to look similar, so close attention pays off. The full set of flags is below if you want to study first.

    How the flags quiz works

    Each question shows a national flag in its official proportions, so a square or unusually long flag is itself a clue. You choose from four countries: the answer, up to three neighbours in the same region, and, if the flag has a well-known lookalike, usually that lookalike too, from our guide to similar flags. One point per correct answer; the streak counts correct answers in a row.

    Two pairs are never offered against each other: Romania and Chad, and Indonesia and Monaco. On a screen, the only differences are a shade of blue or the flag’s proportions, which is not a fair test of knowledge.

    Commonly confused flags

    10 of the ten pairs in our lookalike guideinvolve these flags. The clue below each is the most dependable way to tell them apart.

    Flags with almost the same colours

    These pairs have the closest measured palettes, after excluding the pairs above. They share colours, not necessarily layout, so check stripe direction, emblems and stars.
