This board game will make you a math genius, and it is actually way fun!

Geektastic Dad

Honestly, this has got to be one of the most engaging and effective ways of introducing the idea of primes being the ‘building blocks’ of numbers and building other general logic skills… Overall, Prime Climb is an incredibly flexible game, and certainly met the high expectations it set itself.


By far one of my favorite game releases of 2014…. I cannot get over beauty and functionality of this game!

This is an amazing game! It is genius actually. You can play this with both young and old and adapt it to anyone’s ability. Players must not only use their math skills but their strategy skills as well. I believe this game should be in every classroom in America as well as every home!!

Benjamin Leis, Running a Math Club: My Experiences

Take a look at Prime Climb, an excellent new game… perfect for adults and children alike.


Prime Climb is an excellent way to teach about prime numbers, factors, common multiples, and that math is fun!… I loved how Prime Climb engaged my math loving kids and my kids who tolerate math. It was engaging and challenging enough that no one was bored, but easy enough to understand that no one was frustrated. It was the perfect balance. (It was fun for the adults as well.)
