Type 'easy' or 'hard' to begin the quiz. Easy is a 15-degree grid, hard is a 10-degree grid. Then, try to name the LARGEST city in each grid square which fits the category label for each square. The grid will be placed randomly each time. To name a city, you must first click on the grid square to make it have a GREEN border. Then, type in the city answer for that square followed by a '.' (a period). You are given a score from 0 to 100 based on your answer's population compared to the largest city accepted in that square (100 being you named the largest city).
LETTER: means the city starts with that letter.
NUMBER RANGE: (such as 2-5, 10+) means the city contains that many letters (excluding spaces and special characters).
POPULATION RANGE: (such as 50-100K) means the city has that range for its population.
2+ WORDS means the city name has 2 or more words (words denoted by a space or hyphen).
At the end of the quiz the largest population missed answer will show in each unanswered square, and for those answered the largest city will be listed if you didn't answer it.

For some reason I don’t feel like expert mode has enough time, and I have Premium. Unless this is due to me being on mobile
I’ll bump it up.

What is the coty that abuts Perth, Australia?
In intermediate difficulty, what is the city in the square over east Sri Lanka? I’ve tried all the largest cities there.
Also Suva, Fiji doesn’t seem to be working. I’d assume thats the largest city in that square.
Nasinu is actually the biggest city in Fiji city proper.
it’s kalmunai
On the beginner level, it is saying Karachi has a larger population than Mumbai? Karachi has 14 million to Mumbai’s 21.
my city proper populations are from citypopulation.de…you may be referring to metro area
even in city proper, i believe mumbai has more
Karachi has a couple million more city proper.
On the expert level there is a square in Alberta and I am sure the answer is Fort Mcmurray yet no matter how much I try different ways to spell it I can’t seem to get it correct. Is there another spelling I am not aware of? If so I would love to know it! Thank you!
Fort McMurray is a urban service area and not included…it’s Wood Buffalo
Where can we get the answers ?

Update in Johannesburg vs Lusaka:
I searched up both cities in “citypopulation.de” and I got 7,860,781 for Johannesburg and 1,747,152 for Lusaka. Could there be something wrong with the “Beginner” grid?
Here are the links I used:
https://citypopulation.de/en/southafrica/cities/
https://citypopulation.de/en/zambia/cities/
that’s a urban center Johannesburg population. it includes a number of cities outside the city limits.
Is this what you’re using then? https://citypopulation.de/en/southafrica/cityofjohannesburg/
“Main Places” within each municipality? (Johannesburg 957,441)
yes
Also, “Diego-Suarez” was changed to “Antsiranana” in 1975. Had to really cross-reference that one!
both are accepted.
Also, why in “Beginner” is Lusaka considered the largest in the grid when Johannesburg is the more populated one?
not according to city proper at citypopulation.de
“Taipei” really should count for “New Taipei City”.
they are different cities, so I have them separated.
Wow! You are really fast!
