South America Population Coverage
DirectionsChoose a level. Then, begin naming cities. All cities of 50K+ population starting with the city you chose and moving outward will begin filling in until you’ve hit a total population equal to or greater than your chosen level’s threshold. For example, if you choose ‘int’ – the threshold is 5 million. If you choose ‘quito’, then Quito will fill in and because its population is under 5 million, successive cities moving outward from Quito will fill in until the total population reaches at least 5 million. If you chose Sao Paulo, only it would fill in as its population already meets your threshold.

About balancing. Could a 2.5mil population per circle difficulty be added for non-premium users. As intermediate (5mil) is quite easy and advanced (1mil) is really hard. Is a middle ground plausible.
Going to leave as-is for now, sorry.
