Identify flags from 195+ countries. Pick a continent, choose easy/medium/hard, and track which flags you keep missing so you can drill them.
The Flag Quiz shows you a national flag and asks you to name the country. Filter by continent, pick a difficulty (easy = 4 options, hard = 6), and the game remembers which flags trip you up so you can revisit them later.
Flags you miss are tagged in your local mistake list and prioritised in the "Practice weak" queue on the country page — so weak flags come back until they stick.
Flags are pure visual recall. Recognising them in a shortlist is easy; naming them cold is where actual learning happens. The mistake-tracking loop closes the gap between "I've seen it" and "I know it".
