How to Play

First, a state lights up. Choose its name from the buttons. When you get it right, a capital star appears. Then choose the capital city.

Misses are friendly: you’ll hear a soft bouncy sound and see the correct answer plus a fun fact. States you miss take a short break before coming back.

Race the States gives you 4 minutes. It skips the big zoom animations and keeps the map close-up so you can fly.
