First choose any Europe 10K+ pop city by entering it and choosing it in the drop-down box. Then, name any Europe 10K+ city in each 100 km circle/ring as the rings expand outward from your city of choice, trying to name SECOND LARGEST city in each circle. The first circle will include your city of choice as a possible answer.
PLEASE NOTE - You must type a '.' (period) after each city to submit it to prevent answering another city with a name you would be have to type to get your answer. If multiple cities have the name you submitted, only the largest one will be counted.
You accumulate points based on the population of the city you named in relation to the second largest city in the circle. A smaller city’s point total will be the ratio of its population to the largest, so if you name a city of 75K people and the largest city has 100K, you get 75 points. Naming the largest city will get you points based on the ratio of the 2nd largest city's population to the largest city's.
When you run out of time or end the quiz, you will see the current ring’s 2nd largest city at right (under ‘Answer Stats’ by your coordinates).
For example, if you choose ‘Paris’ – you will be shown a circle of radius 100 km centered at Paris. Naming any city in this circle (including Paris) will cause another ‘ring’ of radius 100 km to appear outside that circle, however - you will want to try naming the SECOND LARGEST city you can to get more points. After completing that circle, you now need to name any 10K+ Europe city in the new ring (but not within any previous circles/rings), again trying to name the 2nd largest city. If there are not two cities within the next ring of that distance, the ring will keep expanding by that distance until two cities fall within it.
Quiz Takers 
as a follow-up, yeah these letter-count place name quizzes did have me pick a unique letter count for each city, but if there are alternatives with the same # of letters i will add them. some cities are going to be just a judgment call on my part – sometimes i use the name English Wikipedia has for the city name if i can’t decide.
Yes, you’re right, 1516, but quizzes like these for the most part require you to keep to a specific spelling, e. g. Navapolack. Anyway, there may be a lot of cases I’m not aware of allowing more than one spelling. Knowing the requested spelling is enough for these quizzes, though 🙂
You’re right, there are a lot alternative spellings on largest cities quizzes… even recently I’ve asked for Salonica/Salonika to be accepted for Thessaloniki. It’s still waiting for approval I think.
Actually, I was referring to the possibility of multiple spellings in quizzes like this one, which are “stricter” than the Largest Cities’ ones. I’m no expert as to alternative names, so there may be a shorter or a longer version of a city name I don’t know or I’m not thinking of that can be accepted (much like Luik/Liège or Gent/Ghent).
I keep trying to type “navapolatsk”, but it’s not working for some reason. Yet it shows up in the results section.
You have to type “Navapolack”, which has 10 letters, while “Navapolatsk” has 11 letters. In the European Cities quizzes based on the number of letters in their names (like this one), you have to keep to the requested number of letters, so alternative names aren’t accepted if they don’t have that specific number of letters.
however Luik is accepted for Liège and Gent for Ghent in the largest 5-letter cities
Does the lack or the inclusion of some alternative spellings detract from the enjoyment of playing the quiz in any way? I mean, either you know the cities or you don’t… otherwise you’ll make Darin go through all the quizzes on the series adding and subtractng names for more than its worth. Regular largest cities quizzes have a ton of alternative spellings, better play this one straight.
Yes if there are some quizzes where an answer is accepted if it doesn’t have the same amount of letters but on others it isn’t
Ok, to each his own but given the idea behing these letter quizzes you’ll most likely see the removal of any alternatives than the adding of new ones. That if Darin cares one bit.
yeah those shouldn’t be accepted in the 5-letter quiz i’ll remove them from that.
Ah, I see. I was just confused because “navapolatsk” is what shows up in the results. I figure darin should at least have it as “navapolack” in the results if that’s what’s accepted, or just have the city in an 11-letters game. Sometimes I don’t count right when the letters get more than about 6.
Yes, it may be a bit demanding when you have to deal with longer names (in my case, over 7/8 letters long) in a quiz like this one; it’s easier for me to forget city names I wouldn’t normally leave out in other quizzes. As to Navapolatsk, I think the spoiler may prevent further problems with its spelling 🙂
can you accept Goteborg, St Denis, Krasnograd and Yenakievo please
This is a quiz based on number of letters, so better keep their 10-letter offical versions.
yeah for these quizzes you need to type the versions consistent with the number of letters in the quiz.
Krasnograd is 10 letters and Yenakiyevo too
Yenakiyevo wasn’t when you first posted. Still I think it’s a bit redundant to ask for alternative names with the same number of letters… even more if you know the city name the quiz is asking.
well I actually missed Yenakiyevo ’cause I didn’t put the spelling the quiz accepted
adding those two alt spellings that also have 10 letters.
