DaYan Gem II
Click a thumbnail to see its larger version and description.
A hybrid of a 3x3x3 and a helicopter cube.

This is the first mass produced hybrid of an face-turning and edge-turning hexahedron. The puzzle has two cuts per axis for both axis systems. Its shape is something between a truncated ocathedron and a cuboctahedron both of which are archimedean solids. A puzzle in hexahedral shape would have needed additional pieces. Therefore this shape was used.
Distance between the squares: 75 mm
Weight: 206 grams
