This puzzle contains 1 spherical core, 60 centers, 140 edges and 150 corners. To make it more complex, this puzzle jumbles too, which means that some moves may be blocked by other pieces. These blocks can not be fully removed.

This puzzle is based on the geometry of a Pentagonal hexecontahedron, which is the dual of the snub dodecahedron, being the largest archimedean solid.

If one would want to sticker this puzzle, 72 different colours would be needed and one would have over 800 faces to sticker. To avoid this the creator decided to dye the puzzle's pieces in a nice pattern instead.

Edge length: 11 mm
Diameter: 85 mm (outer)
Weight: 144 grams
