A new challenge appears! You are provided with 5 sets of randomly generated cities, you must arrange them in order of population (most to least). You get 3 tries per round to sort. Upon a check, a city will lock in its place if it's in the correct spot. You will be rewarded based on how well you perform.
Population based on urban area, as per JetPunk data.
