As mentioned before, I am not aware of the Type-Ins of the standard quiz on Countries of the World. But I think, it accepts too many different typings anyway, which fosters the learning of incorrect spellings.
My point is here that people who challenge an "expert quiz" should not only know the countries but also the correct english spelling. For my part, I am also not a native speaker (as you may have noticed) and just learned it by repeating the quizzes.
Anyway, thank you for your suggestions. I added most of them to the list, except for "Kazakistan", which I've never heard of and which according to Google is turkish language.
I hope you can enjoy it though :)
I keep forgetting 1, usually Moldova or East Timor.
Actually, it is spelled Liechtenstein. But I added Lichtenstein now anyway.
As mentioned above, I don't think that too many different accepted type-ins are helpful to learn the countries in a proper way.
Same for Saint-Kitts instead of the long form?
This is common practice on most quizzes on here.
Great quiz though!
Can you accept Vatican for Vatican City and eSwatini for Swaziland?
