The object of this quiz is to adjust each circle's radius so it contains the target population shown at the right but ONLY within Europe. When you click Start you will be shown a marker on a random populated Europe grid square (there are over 90K 10x10 km grid squares used for the data, courtesy of https://human-settlement.emergency.copernicus.eu/index.php). Also you will see an adjustable circle of radius 100 km to start. Adjust the circle's radius by dragging it until it contains the target number of people shown - this target will be between 5 and 100 million people. Then click submit. You are scored on how close your circle's population is to the target.
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.
turkey is definitely wrong. there are many cities with millions of population but you added only istanbul
It’s just the ones in Europe – I’ll add a note in description.
How often does the quiz get updated? I realised today that the list for moldova changed a bit.
Once in a while, it’s not live.
at Romania and at France there are missing citys
I see all 10, and they are based on citypopulation.de
What’s the source for Montenegro? Shouldn’t Herceg Novi be on the list? It is in the top ten of the recent censuses that I’m seeing.

Herceg Novi is on your link at #5 for the 2023 census, but it doesn’t show up on the quiz.
What is your source for Albania? I know it is tough to get firm numbers for that, but the last two cities don’t show up on several reputable population lists. On a related note, I looked up Paskuqan, and it appears it became part of Kamez in 2015.
Yeah I found a separate source other than citypopulation.de for Albania. It looks like Paskuqan is still its own city though, even though it became part of the municipal unit of Kamez.
I’m not quite sure what “patos, albania” is doing in the list. several sources list it with 15.000 people or less, which would not make it in the top10 of albania.
I see a couple with 32k for it…Albania was a little tough to get firm numbers for.
Would be nice to see the country for each city in the “missed” sections after surrendering 🙂
I think quizzes like these need a better time bonus system. You can get five minutes of extra time if you just enter two cities (Monaco and Serravalle), but you can also get zero minutes for entering 80 cities if you are unable to name a lot of cities in a single country.
Italy is deceptively easy. Those two cities you list plus Italy should be enough for just about everyone to get to 100.
I’m Spanish and I got Italy before Spain lol
Can there be an easier option that Just has a bigger time limit? because 5 minutes is not enough
there are time bonuses throughout for all users, and premium members get double time and double time bonuses
anyways 10 minutes to name 421 city is not enough
Start by typing the largest cities of Monaco, San Marino and Andorra and you’ll have more time 🙂
