World City Random Grid
DirectionsFirst choose a difficulty by typing ‘beg’, ‘int’, ‘adv, or ‘exp’ – Beginner is 15 degrees, Intermediate 10 degrees, Advanced 5 degrees, and Expert 2.5 degrees. A grid of your chosen square size will be placed randomly on the map. Then, enter the largest city (min 50K population) in each grid square of the size based on your difficulty. Green squares contain answers. Adv and Exp levels may take a few moments to load.
hugequiz Premium members will see the top 25 missed cities at the end of the quiz as purple markers.

Why is As Seeb > Muscat when they are in the same square?
nvm – i see that there is a difference between the city of muscat and metropolitan area
Should Mohe City be counted? It covers 18,367 square kilometers and contains several towns distantly apart but none which are bigger than 50k
Yeah it’s listed here so I count it:

Strange that cities like Minneapolis, Khartoum, Manila, and Guadalajara don’t work. I understand you’re probably using a specific definition of city, but I would argue those make more sense for their respective squares than the actual answers.
Cities are based on city proper populations from citypopulation.de. You can’t use metros as that will then double-count the cities within metro areas.
Why doesn’t it show every single pin I missed?
Please fix when after ending quiz on beginner why I cannot see every city that I missed, only the top 25. Based on top instructions it seems like a design decision. I struggle to understand why that is a design decision unless it is a technology limitation.
It’s design based as showing all answers makes people copy them and cheat, sadly.
The coordinates of Coari (in the State of Amazonas, Brazil) are a quite a bit off, by about 75 miles
it’s actually a very large municipality area so those coordinates are actually the center.
Can’t for the life of me figure out what the answer is on intermediate mode when the square falls east of Manaus, west of Belem, south of Macapa and north of Sinop – Santarem seems like it should be the answer but the quiz won’t accept it. Also is Merauke not in your dataset?
Otherwise, great quiz! might be the best on this site, thanks Darin 🙂
The only Indonesia places are actual cities per my source:
https://citypopulation.de/en/indonesia/cities/sett/
Many others are districts – so very large areas with many places in them.
Merauke is listed in this dataset with the latest (2010) census showing a population of 86,782 so it should be in the quiz, no?
Yeah but it doesn’t have ‘City’ in the column next to it – those are not actual cities. In some cases they are large districts.
Looking at the Indonesia Largest Cities quiz it is there in the database, it’s just using urban communes data which split the town into 8 different urban communes (all of which within the town itslef) with a combined population of 86,782 while the district as a whole has 87,634 both using 2010 census.
I really don’t understand your reasoning for opting to use urban communes cutting the settlements up into countless pieces instead of overcounting them slightly.
I don’t think anyone want to learn the urban communes of: Bambu Pemali, Karang Indah, Kelapa Lima, Mandala, Maro, Rimba Jaya, Samkai and Seringgu Jaya instead of Merauke.
darwin has a smaller pop. than i thought
Tarlac (Philippines) seems to have the wrong population count: according to citypopulation.de, it has 271455 from the 2020 census, but it seems to show up as 385398 (I got the count from the city coverage quiz)
number is from here: http://citypopulation.de/en/philippines/luzon/admin/tarlac/036916__tarlac/
Is there a way to do this without a time restraint?
Premium members can click on ‘Untimed’ after the quiz starts – score will not be saved however.
I love this quiz! I particularly enjoy the random element. Unfortunately, I do not get the stats when I finish. It keeps saying ‘calculating stats’. Do you not get stats if you do the quiz untimed or if you paused it?
oh sorry these grid quizzes don’t have stats.
depending on how the grid places on the map there may not be a 50K+ city within a square…can you email me a screenshot if i’m not understanding your comment correctly?
actually found the issue – fixing now.
