About StatStack

StatStack is a free daily statistics game where you guess which of two real-world facts has the higher number. Test your intuition against real data — from populations and distances to speeds, revenues, and more.

How It Works

Every day at midnight, a new set of 10 rounds is generated. Every player in the world gets the same questions on the same day. You're shown two statistics — one value is revealed, and you guess whether the hidden stat is higher or lower.

After playing, share your results grid with friends and see who knows their numbers best!

The Data

All statistics in StatStack come from verified public sources including government agencies (NASA, US Census, UN), official records, and established reference databases. Sources are displayed for every statistic so you can verify them yourself.
