World 50K+ Latitude Coverage Challenge


First chose a difficulty by typing ‘beg’, ‘int’, ‘adv, or ‘exp’ – Beginner is 2 degrees latitude, Intermediate 1 degrees, Advanced 0.5 degrees, and Expert 0.25 degrees. Then, enter 50K+ population cities and all 50K+ population cities within that latitude will automatically fill in.

HOWEVER – for this quiz you can enter any 50K+ 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 – you can mouseover them to see city details for each.

Enter level to begin ('beg', 'int', 'adv', or 'exp').


  1. Senhor do Bonfirm, Bahia, Brazil isn’t accepted despite being shown on the map.

    Also, this quiz needs some optimization. I was playing expert, and it was getting extremely choppy after I had entered a few hundred cities to the point I had to open a new tab to type up a comment. Maybe merge the rectangles when they overlap?
