The remarkable 21-Piece Pyramid Puzzle was originally constructed and designed by David Hirsch. The puzzle offers 120 challenges in many levels of difficulty, starting from the most simple tasks and gradually moving towards more complex tasks. The smooth, lightweight, yet large size of the pieces also makes it an educational puzzle for children. The solid base of the pyramid also allows the puzzle to be displayed on a coffee table or desk to entertain friends and colleagues for hours upon hours with new challenges.
