Abstract
The Pyramid Puzzle is a toy puzzle incorporating a ball hidden inside a pyramid. By chance rotation of the various levels of the pyramid the ball drops through the levels of the pyramid. When the ball falls into a blind (partial) hole, the pyramid must be manipulated to reorient the ball so that it may fall freely down to the next level. The puzzle is solved by retrieving the ball in a sliding tray at the base of the pyramid.
