Twelve identically shaped sticks magnetically connect in this hands-on learning puzzle.
"In the category of Educational Toy That Could Pass for a Real Toy, the high scorer was Tetraxis, a magnetic geometry puzzle, in which you try to assemble colorful geometric pieces into a whole. It's challenging but not throw-it-across-the-room challenging. Bonus points for knowing that the structure is arranged along directions common in nature, similar to carbon and silicon atoms. This factoid also makes for a dandy conversation stopper."

by Patricia Marx
"The Tetraxis puzzle is absolutely beautiful. In 5 decades of being involved with toys and toy design I have not seen any better. It is at the top in quality, concept, design, function, safety and play value. It is truly a timeless toy that is a perfect gift for all ages. I am so impressed."

“Our three kids love these toys – they are challenging for the adults but our 9-year-old puts it together blindfolded and beats everyone!”
