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. For example, if you choose ‘3’ you are only naming the 3 largest cities in each 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).
