The object of this quiz is to click on the circle containing the largest population. When you begin you'll be shown 2 circles with radii between 100 and 2500 km on the map which do not intersect. Click on the one with the larger population within it (based world 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.
First choose a grid size by typing '30', '20', or '10'. A grid of that size lat/long will be placed on the map (so if you choose '20' the grid width and height will be 20 degrees). Then, double click on the grid square with the highest population within it (based on world 10km x 10km population density estimates). The highest-population remaining square will give you 100 points, all the way down to 0 for the one with the smallest population. Try to obtain the most points by successively double-clicking on the highest-populated grid square.
The object of this quiz is to adjust each circle's radius so it contains the target population shown at the right. When you click Start you will be shown a marker on a random populated world grid square (there are over 800K 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 500 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 2.5 and 250 million people. Then click submit. You are scored on how close your circle's population is to the target.
I feel like this would work really well as a map quiz! In this format it can be hard to keep track of what you are missing and what you already typed, especially for China and India. Would be super cool with a version where you could see the locations of the missing cities!
Honestly what is with the timing on some of these quizzes? Even if I could think of all of these cities in rapid succession and typed a hundred wpm I still wouldn’t have enough time to type them all.
I respect all the work you put into these quizzes, and appreciate that you’re trying to mix it up to keep it interesting with the time bonuses. But I feel like most people would just prefer to simply have the time to exhaust their knowledge fully, because as it’s set up now it’s as much, if not more, about knowing what order to type the answers in rather than whether you know the answers or not. Example: You could know 98% of the answers, but if the answers you don’t know include, say, a couple in China, a couple in India, and one in Japan, you have zero hope of having enough time to type all the answers you know. Anyway, just one man’s opinion. Again, regardless of my critiques, I thank you and appreciate you for putting this all together!
Some of these seem not right. For example Oslo, Vienna and Copenhagen are included although they have far less then 1m inhabitants, Tokyo has way less then in Reality as well… What numbers are used here?

update please and thank you!
This quiz is basically live, even though the date updated date may be in the past. It’s current with citypopulation.de at all times 🙂

there are bonuses along the way for almost all quizzes, and double time for PremIum members.

The time limit is way too low, I know all the cities but can’t type them fast enough
Agreed
kinda agree
SO OH GOOD!!!

citypopulation.de…all of those are over 1 million
Vienna definitely has more than a million…you might be right about Oslo and Copenhagen though…
Wikipedia — Population of 11th (10th?) Largest city in USA — 1,028,225 (US, TX)
that’s an estimated 2022 population – I’m using the 2020 census. I do update with estimates every few years but haven’t yet. Maybe next year.
