Diogo's Crystal is a puzzle based on the geometry developed by Diogo Sousa. The shape is similar to my previous Madness Plus puzzle, but has been altered to create equal dihedral angles at the upper and lower sets of vertices. This allows the three side faces (rhombic faces) to have jumbling interactions with the other six faces, creating more opportunity for scrambling. This is also the same geometry that Diogo used on his Hexapod puzzle. Turning is very nice and the core is stable. The Diogo's Crystal comes fully assembled and stickered. Enjoy!
