Guide
Geo Blackjack is city-by-city
Geo Blackjack asks you to reason about individual city populations. Each draw changes the total and the risk of busting.
Headcount is area-by-area
Headcount asks you to reason about population density. The question is not which city is larger, but how many people live inside the shape you draw.
Different pressure
Geo Blackjack is a hit-or-stand pressure game. Headcount is a spatial precision game. Both teach population scale, but the thinking feels different.
Which should you play first?
Start with Geo Blackjack if you want a fast round. Start with Headcount if you want a visual map challenge.
