About Primes
Primes is a game where there are two types of balls coming which have 7 or 9 printed on them. They are to be collected in bowls filled with prime-numbered balls or non-prime numbered balls respectively which swap each other by mouse-click hold and release. Have fun :) Primes is unblocked on SolveCalcPro: it runs directly in this page, with no sign-up and no download, so it works the same way on a school Chromebook as on a home computer.
How to play
Hold release the mouse to swap bowls between blue and red balls
