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.

this challenge is impossible for Toronto it wont let me enter port union, the Kingsway, Scarborough junction, the Toronto islands, cabbage town, harbourfront, and bedford park. what i just listed are names of neighborhoods that when i highlight google maps match the shape of what i am missing so this challenge either some incorrect names or its broken.
It looks like Toronto updated their neighborhoods in 2022…I’ll try to get it updated to the current 158.
Edit: I’ve updated this to the current 158 official neighborhoods. Keep in mind you have to name them pretty spot-on with how the city officially named them.
