A Toy That Grows With You

KnuckleStrutz “grows up” with you. Younger builders piece together snakes and chains, creating colorful patterns or funky robots that perform all kinds of surprising tasks. More advanced building really dives into the toys’ potential, making anything from wing-beating to life-like representations of their favorite vehicles to race their friends

Learn Through Play

Many kids don’t want another “Educational Toy,” but with Knucklestrutz they will get a toy they don’t want to stop playing with AND they will be developing (among other things) critical thinking skills as they use the iterative scientific method of trial and error to create from their understanding of the world around them.
