Test your engineering skills with this deceptively simple looking Ball Pyramid Puzzle. Our intriguing brain teaser, composed of 20 white, wooden balls, is much harder than it seems at first glance! The pyramid structure looks as if each individual ball is separate, but they are actually joined together to form 6 unique pieces that, when positioned correctly, form a tetrahedron (that’s just a fancy word for a triangle based pyramid)! The goal is to be able to reform the tetrahedron after you’ve taken the 6 pieces apart, using your spatial reasoning skills to visualize how they fit together.
