North America City Grid Challenge


Choose a number of cities by typing ‘3’, ‘5’, or ’10’. Then, enter the largest number of 10K+ population cities you chose in each 5-degree grid square. Only green squares contain answers. When you have 2 left to go in a square it will fill in faintly yellow, 1 left it will be orangish, and all done it turns red. A time bonus is given for completing a square (it is greater for higher levels).

Enter '3', '5', or '10' to begin.


  1. Seems like Cuauhtemoc (Chihuahua) and Escuinapa (Sinaloa) aren’t registering on the 10 grid. I’m pretty certain Cuauhtemoc should be on there and moderately certain about Escuinapa.
