100 of Us
What is 100 of Us?
100 of Us is a daily browser game that asks how many people out of 100 worldwide fit a given statement. You estimate a number from 0 to 100, lock it in, and then see the real figure from World Bank data. Everyone gets the same question each day, and a fresh question arrives at midnight.

Perfect little brain break — hold, slide, let go, and you've learned something about the world before your coffee gets cold.

A daily nudge that turns World Bank data into a game, making you feel the planet's scale and your own guesswork in one quick round.
How to play 100 of Us
Press and hold to make the crowd count up; slide right to add more and left to subtract, then let go when you reach your estimate. A single tap adds one, and you can hold again to adjust or tap Redo to clear your guess. When you are ready, tap Lock in to reveal the correct answer.
Tips & strategy
- Anchor your guess with a rough percentage you already know, then adjust up or down based on the question.
- Use the slide gesture to move quickly to large numbers instead of tapping one by one.
- Think about whether the question relates to broad global patterns, like population distribution, gender, or development, to narrow your range.
- If your first estimate feels wrong, use Redo before locking in—only your locked-in guess is compared to the real number.
- Remember the scale is the whole world, so very small or very large extremes are usually unlikely unless the question is about a narrow group.
