US City Grid Challenge
DirectionsChoose a number of cities by typing ‘3’, ‘5’, or ’10’. Then, enter the largest number of 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).
I’m filling in all these cities but none of the grids are highlighting? Is there a rule I’m missing?
please read directions. for level ‘3’ for example you are naming only the 3 biggest cities in each grid square
