Primes

Primes sends two kinds of balls, marked 7 or 9, into bowls that must hold prime or non-prime numbers, and you swap them by holding and releasing the mouse.

How To Play Primes

Hold and release the mouse to swap the bowls between blue and red balls.

Controls and Features

The only control is holding and releasing the mouse button to swap the bowls. Balls arrive marked 7 or 9 and must land in prime or non-prime bowls.

Tips

Watch which ball is coming and swap the bowls at the right moment. Remember that 7 is prime while 9 is not, so each needs its own bowl.
