Pennyhedron Senior

Description

Pennyhedron Senior is a more difficult rhombic-triacontahedron version of Steward Coffin's famous Pennyhedron puzzle. The original Pennyhedron has rhombic-dodecahedron shape. That puzzle can be pulled apart by putting three fingers from each hand at the right places on the faces. The challenge is where to put ones fingers, as all faces look the same. Surprisingly, many people have difficulty solving Pennyhedron, even when the two pieces have different colors. So Pennyhedron Senior may be a good puzzle for those who have already solved the original Pennyhedron.
