195 countries · 22 look-alike groups
195 flags, taught one at a time. Spaced repetition moves each flag up its own ladder — so you actually remember them, not just recognise them for a second.
The method
Get it right and a flag climbs a rung, with a longer wait before it returns. Slip up and it drops back — but never below rung 1 once you've met it. That's spaced repetition, quietly doing the work.
Flag, name and a few curated facts — no test yet.
Name shown → pick the matching flag.
Flag shown → choose the name from four.
Down to two — the look-alike is the trap.
Free input, fuzzy-matched for typos and aliases.
Only the occasional review to keep it sharp.

Most quizzes ignore the hard part. We built the wrong answers out of the real look-alikes, so the difference is exactly what you practise.
Blue-yellow-red vertical
Tell them apart: Chad's blue is a touch darker — otherwise near-identical. In 2004 Romania even raised it at the UN.
Red-white-blue horizontal
Tell them apart: Luxembourg's blue is lighter and the flag is longer.
Red over white
Tell them apart: only the proportion — Monaco is almost square.
Orange-white-green + a disc
Tell them apart: Niger's centre is a plain orange sun; India's is the blue Ashoka wheel.
Denmark · Sweden · Norway · Finland · Iceland
Tell them apart: same off-centre cross — colour and the cross-within-cross decide.
Mali · Senegal · Guinea · Cameroon
Tell them apart: Senegal adds a green star, Guinea reverses the order, Cameroon swaps to green-red-yellow.
