Choose a mechanic: draw, compare, or draw cards
Choose Headcount to draw on a population-density map, HigherQ to compare city populations, or Geo Blackjack for a press-your-luck population hand. Mapfold is a related option: use population and other country facts to find a hidden country.
Headcount: five targets, one loop per round
Headcount gives you five daily targets and a glowing world population map. In this draw-a-circle-around-population game, draw one freehand loop per target and submit it blind to reveal the population and score. Each round is worth 100 points, for a daily total out of 500. After all five rounds, practice offers fresh targets with results revealed on submission.
Mapfold: country deduction with population clues
Mapfold hides a country. Population is one possible clue among country facts that divide the remaining candidates; a miss folds away the ruled-out part of the world. Mapfold does not cut a country or the world into equal population shares. For literal splitting, GeoSlice’s rules describe halves, thirds and quarters. The same site also lists Inner Circle, a five-round population-loop game; compare the specific mechanic rather than assuming the brand identifies only one game.
HigherQ and Geo Blackjack: compare or play to 21M
HigherQ asks which of two cities has more people and turns every correct comparison into an endless streak. Geo Blackjack uses city populations as card values: hit or stand against a dealer and try to finish near 21 million without going over.
What the population numbers mean
Headcount uses a modeled population grid, so it measures people inside the exact shape you draw rather than adding political units. The city games use a consistent city-population definition for fair comparisons. Estimates have reference years and boundaries, so the games teach scale rather than pretending every population figure is permanent or exact.
