The Pentamid puzzle is based on the geometry of the pentagonal dipyramid. It turns on the five edges around the equator of the puzzle, as well as on the two polar vertices. Each vertex can turn in increments of 72 degrees, while the edges are limited to 180 degree turns. The Pentamid puzzle becomes scrambled fairly quicky with just a few turns. This beautiful puzzle is stable and turns very smoothly. It comes fully assembled and stickered. Have fun!
