Choose a number of cities by typing ‘3’, ‘5’, or ’10’. A random 15-degree by 15-degree grid will be placed on the map. Enter the largest number of cities you chose in each square (min 10K population). 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).

For example, if you choose ‘3’ for your number of cities to start the quiz, only the 3 largest cities in each grid square will be accepted as answers.
