First choose any state by typing the state’s abbreviation (i.e. ‘OH’) – then, double-click on the marker for each of the top 100 largest cities (or less for a few states that don’t have 100 cities) in that state as they come up. Markers will all be red to begin. Clicking on a the correct shown city will turn the marker green. Clicking on the incorrect city will cause no change in the markers.

Note – you may want to zoom in on markers which are close to one another to make sure you click on the correct marker.

If red markers do not appear after you choose a state try reloading the quiz.
