Why you'll like it
A genuine collector's puzzle: A 30-face rhombic triacontahedron with curvy face-turning cuts is rare, complex geometry you won't find in a standard lineup.
Deeper cuts, deeper solve: The Plus build takes the curvy face-turning mechanism further, adding layers and interactions the standard version doesn't have.
Striking display piece: The stained-glass look of the curved cuts across 30 faces makes this as much a shelf centerpiece as a puzzle.
Performance & design highlights
Curvy face-turning mechanism: Every rhombic face turns on curved cut lines, splitting each face into multiple interacting pieces.
Rhombic triacontahedron shape: 30 identical rhombic faces built into a rounded, hand-friendly form.
Black plastic base: High-contrast black frame that makes the colored faces pop and reads cleanly during a solve.
Best fit for collectors who want the hardest version of this rhombic triacontahedron, with the extra cutting depth the standard build leaves on the table.
