Flagle shows one flag a day in tiles. Good puzzle, hard limit. If you want to keep going, these free flag games have no daily cap.
1. Flag to Country
Flag to Country shows a flag and asks for the country. Every national flag, unlimited rounds, misses shown instantly.
2. Country to Flag
Country to Flag runs the reverse direction, which is harder and exposes gaps the first mode hides.
3. Lookalike Flags
Lookalike Flags is built entirely from the confusing pairs — Chad and Romania, Indonesia and Monaco, Ireland and Ivory Coast, Norway and Iceland. This is where flag quizzes are actually won.
4–7. Flags by continent
Continent sets are the fastest way to improve, because you learn a colour family at a time instead of random flags.
8. Daily Flag
Daily Flag keeps the one-a-day ritual if you like it — with an archive so you can catch up.
The shortcut to a high flag score
Learn the four colour families first: the Nordic crosses (Denmark, Norway, Sweden, Finland, Iceland), the Pan-African colours of red, gold and green, the Pan-Arab red, white, black and green, and the Pan-Slavic red, white and blue. Those families cover a large share of the world's flags. After that, the only thing standing between you and a near-perfect score is the lookalike list.
Look anything up in the flag lookup tool.
