About Primes

Primes is a quick reflex puzzle where you sort numbered balls into the correct bowls based on whether they're prime or not. Balls stamped with 7 or 9 drop from the top of the screen, and you need to catch them in matching containers—one for primes, one for composites. The twist? Your two bowls swap positions every time you click and hold the mouse, so timing is everything. Miss a ball or drop it in the wrong bowl and you'll lose progress. It's a simple mechanic that gets surprisingly frantic as the pace picks up, perfect for a quick mental workout on Poki Games. If you like number challenges mixed with arcade reflexes, this one keeps you on your toes.
