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 cities in each square IN ORDER. 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).
The squares will start with '0/5' (or maybe fewer cities if less exist in that square). Click on a square and enter the largest city in that square not yet answered (so, the largest city if you have yet to answer a city in that square). You will then have '1/5' and need to click on that square to name the 2nd largest city, and so on until you complete all the cities up to 5 (or less if less exist). If you name an incorrect city in a square it becomes 'locked' and turns red and you can no longer accumulate cities in that square.
You receive 1 point for the largest city in a square, 2 for the 2nd largest, and so on.
AK and HI are NOT included in this quiz.
At the end of the quiz the largest remaining city you haven't named will be shown in each square.

It would be great if the neighbourhood names showing up on the map would be optional – right now they make it hard to see the map, especially when zoomed out and you want to see the whole city
you should make one for the capital of canada.. ottawa!
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.
