Guess the Flag Quiz | Ultimate Flag Quiz 20 Flags of the World

Here's a really fun quiz, one of my personal favorite quiz topics in what is perhaps the ultimate flag quiz: We're playing the Guess the Flag quiz, featuring 20 national flags of the world!

For this flag quiz, I have lined up 20 national flags, ordered by population size starting with the most popular country and working our way down to less populated countries. You will see the flags one by one and the challenge is simple as can be: guess the country by the flag.

I hope you enjoy the Guess the Flag quiz! If you play all the way to the end, let me know your score in the comments. For more quiz fun, subscribe to my channel, The Quiz Channel. Thanks!
