First choose a difficulty by typing ‘beg’, ‘int’, ‘adv, or ‘exp’ – Beginner is 0.5 degrees latitude, Intermediate 0.25 degrees, Advanced 0.1 degrees, and Expert 0.05 degrees. Then, enter 1K+ population cities and all 1K+ population cities within that latitude will automatically fill in.

HOWEVER – for this quiz you can enter any 1K+ city for your first choice, but successive cities must be already within a blue band for you to answer them, so you must ‘expand’ the blue area in the north and south directions, you can’t start a new blue band with a gap away from a currently blue shaded area.

hugequiz Premium members will see the 25 largest missed cities at the end of the quiz as large, purple markers.
