Challenge The King #1 – US Largest Cities

Can you beat Geography King?

Your goal is to adjust each circle so it contains the target population shown on the right. When you click START, you’ll be placed at a location with a marker and a circle set to a 100-mile radius – locations for this quiz are the centers of the 10 largest US cities. Drag the circle to resize it until you think it contains the target number of people, then click SUBMIT. Your score is based on how close your circle’s population is to the target. Population is calculated by totaling all U.S. census tracts (small census areas averaging about 4,000 people) that fall within your circle. After each round, you’ll see Geography King’s circle and score for comparison.

⚠️ Important: Once you click START, you only get one official attempt. Any future plays will still work for practice, but your score will not be saved. You CANNOT start the quiz, go through the rounds to see the locations and population targets, then restart to actually play it – once you click START you must complete that quiz for your score to save.

SCORING NOTE: Only U.S. population is counted. Population in Canada and Mexico is not included, even if it falls inside the circle.
