Type 'easy' or 'hard' to begin the quiz. Easy is a 5-degree grid, hard is a 2.5-degree grid. Then, try to name the LARGEST city in each grid square which fits the category label for each square. 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).
AK and HI are NOT included in this quiz as they often have grid squares with only one answer for this quiz.
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.

Is Guadalajara not the largest city in the middle box of western Mexico?
on what difficulty
for some reason when I type saint Francois it doesn’t work even though when I end the game it says that I missed that city. Might be an issue on my end idk
Just curious, how can Mackenzie County, Alberta, end up as the largest “city” in the grid? Wikipedia tells me it’s a “specialized municipality” but also that it’s almost 80 000 km^2! This reminds me of the logic by which Chonqing is officially the largest and most populous city in the world with 30 million people. It all comes down to definitions I guess.
I included specialized munis as they are listed on the Cities & Towns listing on the source:
