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


This game is so rich in mathematical ideas that I literally spent a week investigating it with my class.

Rated #1 Educational Math Game!

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.


This game blew my mind! It blew my wife’s mind, it blew my kid’s mind… it is one of the coolest visualizations of mathematics and prime numbers I’ve ever seen ever. It is awesome!

If you were looking for a Candy Land-esque repetition you are in for a surprise!… a fantastic family game!

Engaged Family Gaming

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.)

Simply Schooling Reviews

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!!

For a game that is a relatively pure experience of math equations, I think you’ll be surprised how much fun it can be for players of all ages.

Tiny Polka Dot

Number-loving Learning Fun

Tiny Polka Dot is the playful way for children ages 3 – 8 and up to fall in love with numbers. With eye-catching, colorful cards and 16 easy-to-learn games, Tiny Polka Dot is built to grow with your child, teaching critical skills in counting, arithmetic, and logic along the way.

I love that the game plays well with even the youngest of children, but some of the included game types scale up to match skills available to slightly older players. I also love that the game includes a brief guide for grownups on how to help kids enjoy and learn as they play. Tiny Polka Dot makes this list for its fun factor, not [just] because of its educational elements.

Then, in a moment out of a sitcom, [my daughter] cheered and cried, “Yay! I can do tough things!” Then gave me a hug.

This… doesn’t happen often in my math classroom..

Matt Vaudrey, Math Teacher

Tiny Polka Dot is absolutely fantastic. It gives J a structure that he enjoys exploring, and when he tires of the Match 7 game, we will move on to Match 8, Match 9, or any of the dozens of games and iterations we can create from these cards.

These cards are going to be part of our playtime for years to come.

We take advantage of the science of memory to make sure you’re actually getting the facts down, accurately and quickly. And we have games, puzzles, and explorations to take the learning further.
