Challenge Chicago Geographer #7 – North American Expanding Circles

Can you beat Chicago Geographer? CG himself takes this quiz one time and your job is to beat his score!

You will begin in Chicago Geographer’s city. Name any North American 10K+ population city in each 100 km circle/ring as the rings expand outward from your city of choice, trying to name the LARGEST CITY in each circle.

PLEASE NOTE – You must type a ‘.’ (period) after each city to submit it to prevent answering another city with a name you would be have to type to get your answer – for example ‘Jackson’ would be answered trying to type ‘Jacksonville.’ If multiple cities have the name you submitted, only the largest one will be counted.

You accumulate points based on the population of the city you named in relation to the largest city in the circle. Naming the largest city will get you 100 points. A smaller city’s point total will be the ratio of its population to the largest, so if you name a city of 75K people and the largest city has 100K, you get 75 points.

When you name a city in the first circle, it will cause another ‘ring’ of radius 100 km to appear outside that circle; you now need to name any North American 10K+ city in the new ring (but not within any previous circles/rings), again trying to name as large a city in that ring as possible. If a city is not within the next ring of that distance, the ring will keep expanding by that distance until a city falls within it.

⚠️ Important: Once you click START, you only get one official attempt. Any future plays will still work for practice, but your score will not be saved.
