Grippie Builders by Guidecraft are the first STEM (science, technology, engineering and mathematics) building toy for toddlers, that combines tactile exploration, magnetic play and an introduction to the basic principles of engineering and geometry. Max likes touching pieces with different textures. Metal balls are over-molded with soft plastic that makes them more attractive to toddlers comparing with #smartmax. I liked that pieces do not slide off balls and fall when Max builds his imperfect tower. On the photo you can see, that Max has missed a couple of pieces in his pyramid, but it still stands upright.
