Begin by typing in any US city/town/etc which doesn’t start with ‘Q’, ‘X’ or ‘Z’ in the format City, State – i.e. ‘Boston, MA’ – for a handful of places with the same name in the same state you will need to add a number corresponding to the population rank of that name in that state – i.e. ‘Madison, WI1’ for the largest of the two Madison, WI’s. That city will appear as a pink marker and the 50 closest cities/towns/etc (not including the one you chose) that begin with the same letter as your city will also appear. ‘Closest Cities’ on bottom left shows the top number of closest cities in a row you have completed (i.e. a ‘3’ if you have the 3 closest but not the 4th). Object is highest population among 50 closest, not total places. High scores only kept for cities of 25K+ population.
