Flags of the world quiz
A flag appears: pick the right country out of four. The wrong answers come from the same continent, which is where it gets tricky.
How to play
- Pick an area (the whole world or one continent) and a number of questions.
- Pick the right answer out of four. A miss shows the correct answer.
- At the end, replay your mistakes: it is the fastest way to remember them. Your best score is kept in your browser.
The 195 flags in the game are those of the UN member and observer states, in their true proportions: the Swiss flag is square, Nepal’s is not a rectangle, Qatar’s is very elongated.
The game deliberately offers countries from the same continent to teach you to tell neighbouring flags apart. Every right answer adds the country’s flag stamp to your passport.
