Primes

About

Primes turns a math concept into a sorting reflex test: balls marked 7 or 9 fall toward a pair of bowls, one collecting primes and one collecting everything else, and you swap the bowls' positions with a click-hold-release to catch each ball correctly. It sounds simple until the balls start falling faster than you can double-check which bowl is which. A neat little game for anyone who actually enjoys mental math under pressure.

Controls

Click and hold to swap the bowls' positions, then release to catch each ball in the right one.

Tips

• Track which bowl is currently "prime" by its role, not its position — swapping moves the bowls around.
• React to a swap immediately; waiting to double-check costs you the next ball.
