First choose any US city by entering it and choosing it in the drop-down box. Then, name ANY US city in each 5 mile circle/ring IN THE SAME STATE as the rings expand outward from your city of choice. The first circle will include your city of choice as a possible answer.

When you run out of time or end the quiz, you will see the current ring’s largest population correct answer at right (under ‘Answer Stats’ by your coordinates).

For example, if you choose ‘Chicago, IL’ – you will be shown a circle of radius 5 miles centered at Chicago. Naming the any Illinois in this circle (Chicago or otherwise) will cause another ‘ring’ of radius 5 miles to appear outside that circle. You now need to name the any US city also in IL in that ring (but not within any previous circles/rings). If an Illinois city is not within the next ring of that distance, the ring will keep expanding by that distance until a IL city falls within it. So if a city doesn’t fall within 5-10 miles, it will expand to be a 5-15 mile ring, then 5-20 mile and so on until a qualifying city is found within the ring.
