This isn't working. Typed in Vaduz and Athens, both correct answers, and got a red pop-up saying it wasn't a correct answer. Not much point in having a quiz if correct answers aren't accepted.
A quiz that already gives the right letters should definitely obmit the type in option imho. I mean, I did use it, but there would've been more than enough time to ponder about the right spelling.
Second try 19/20, got everything except the capital of my own country - Helsinki :D
Nii mäki :)
