Begin by typing in any US city/town/etc 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 100 closest cities/towns/etc to that city (not including the one you chose) will also appear. High scores are kept only for cities of 25K+ population. ‘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 100 closest, not total places.
