How to Play PopuSum
Objective
Your goal is to reach a target population by selecting countries from the world map. You have to use all three guesses!
Rules
  • You have a limited number of guesses (3) to reach the target population. You must use all three guesses!
  • Click on countries on the map to select them as your guesses.
  • You can only select countries from allowed continents (shown at the top of the screen).
  • Once you use a continent, it is removed from your available options.
  • Each country can only be selected once per game.
  • The game ends when you use all your guesses.
Scoring
Your score is based on how close you get to the target population. The closer you are, the better your grade! Try to find the optimal combination of countries.
