Flags Quiz - Learn every country flag, capital and map
Show HN: Learn Flags Quiz

Flags Quiz is an interactive learning platform that helps you master world flags, capitals, and maps through ten different game modes. It features a unique difficulty system that groups countries by how often people get them wrong, so you can start easy and progress to harder challenges. The quizzes cover not only countries but also states, rivers, and oceans, and they adapt to your performance, keeping your progress in your browser. With curated lists of the hardest, most similar, and newest flags, plus detailed flag pages explaining colors and history, Flags Quiz turns flag memorization into an engaging and effective experience.
Wrong answers are chosen deliberately rather than at random. A question about Chad will offer Romania; a question about Monaco will offer Indonesia. Guessing by elimination does not work, which is the point — those are exactly the pairs people get wrong in real life.

This is so cool. We used to play a paper version of this game back home and this really brings back feelings.
Btw, really smooth. It works really well!

Once I got to 37% total countries identified (seen?), it basically stopped showing me new countries. I went through five or so rounds without seeing anything that I hadn’t seen before. Which was gratifying, since I was getting 20/20 every time, but you might tweak it a little to add in new countries more frequently.

Nicely made! I thought I'm good with flags, and then there come a question of jordan, palestine and two more similar flags.
I made a similar but uglier little party game https://geo-dude.com for my kids. Supports up to 4 players

stream of thoughts:
"all countries" doesn't really show all countries. It seems all countries might be in the pool, but there is no weighted randomness, so you end up getting the same flags, and only a few new ones.
Forcing all flags to be in the same aspect ratio really makes the flags look strange, or rather, not how they really are. This also makes things like Monaco/Indonesia identification more difficult, and flags with horizontal stripes to look strange (Sudan, Cuba, etc).
Some flags seem to look odd or broken? Such as Ecuador which looks like a kid drew it and is pretty broken. Some flags have a weird border around them too, as if they haven't been placed or rendered correctly.
I'm not sure if having a list of flags just below the quiz helps the integrity of it. I'm also not sure of all the AI generated stuff. Are people really mixing up Morroco and Veitnam? Getting to that page again is difficult and unclear, you need to click the flag from the country page, or get it wrong in a quiz. I feel it's a little confusing to have separate pages describing the country and flag. Especially considering its a website about flags.

Is there a mode to run through all the countries, instead of just 20?
A while ago I practiced every day on an android app, and the pleasure I got when I finally got 196/196 was extremely satisfying.
I'd also like to recommend that flags of different aspect ratios be shown correctly.
