first to finish the beginner level!
this is incredibly minor but there appears to be a city in Asian Turkey, on the province of Istanbul’s Black Sea coast, I think it might be the town of Şile but not sure
Yeah it’s Sile – will get rid of it from the Europe quizzes when I next update a Euro country.
Got everything dot except for a single, super-elusive 50-100K population dot. Can’t tell if it’s in Iceland or the Canaries or far eastern Russia.

good quiz but I dislike that it’s really hard to see which strip of land I missed, when there are so many stacked on eachother I might have missed one very thin invisible area
you could maybe merge all the blue areas to one without the white borders
