Blackjack rules, geography values
The familiar hit-or-stand decision works because city populations vary wildly. One draw can be harmless, helpful, or catastrophic.
Megacities are high cards
Cities like Tokyo, Delhi, Shanghai, and Sao Paulo behave like dangerous high cards. Smaller cities let you shape the hand with less risk.
The game teaches scale
Players quickly learn that city fame and city population are not the same thing. Some famous capitals are smaller than regional giants.
Part of the population cluster
Geo Blackjack pairs naturally with Headcount and HigherQ for players who want population geography in different formats.
