Why you’ll like it

Rare shape: A curvy face-turning rhombic triacontahedron is not a puzzle you see every day. It stands out on any shelf.
Serious challenge: Thirty faces and curved cuts make for a puzzle that rewards patience and rethinks how you approach a solve.
Display-worthy: The star-and-petal color pattern reads as much as art as it does as a puzzle.

Performance & design highlights

Curvy cut geometry: Curved slices split each rhombic face into an interlocking star pattern, so pieces shift across faces in ways a straight-cut puzzle can’t.
30-face symmetry: The rhombic triacontahedron body gives the puzzle its clean geometric silhouette and its wide, colorful faces.
High-contrast color scheme: Each face carries its own bright color, keeping the pattern readable even mid-scramble.
