The object of this quiz is to click on the circle containing the largest population within Europe. When you begin you'll be shown 2 circles with radii between 50 and 250 km on the map which do not intersect. Click on the one with the larger Europe population within it (based Europe population density info) then 'Submit' - if you are correct you'll move on. One incorrect round and the quiz is over. Every 5 rounds the number of circles on the map will increase by 1. Try to build the longest streak of correct circles. Circles displayed will always be non-intersecting.
PLEASE NOTE: ALL of Turkey is included in counting population (not just European portion), and the portion of Russia west of 61.5 degrees E (just east of Chelyabinsk). Nothing outside Europe (such as Africa or middle east other than Turkey) is included toward the population count within a circle.

I’ve made a few of the neighborhoods a little easier to enter now.
It’s really anoying having to type the articles like “la” and “el” and all names like “La nova esquerra de l’example”, just typing “Esquerra de l’eixample” or similar should be accepted. I lived in Barcelona my whole life and no one says “El poblenou”, it’s just “Poblenou”. Also it didn’t worked “Gràcia” or “Vila de Gràcia”, don’t know why. Very cool anyways! Thanks
Really cool quiz, but I find it impossible to get to 100%. There are some neighbourhoods that for some reason I cannot write with accents or without. Like “el Guinardó”, “el Baix Guinardó”, “Can Baró”, “Torre Baró”, “Baró de Viver”, “Sant Martí de Provençals” and “Provençals de Poblenou”. The issue might be with accents and ç. But then “el Gòtic” or “Vila de Gràcia” are completely fine, so I don’t know…
Furthermore, people generally call the neighbourhoods without the articles “el” and “la” (except maybe three or four), but that’s the official name so… No one can dispute that.
these should work now
