The Jing's Pyraminx is a puzzle in the shape of a Reuleaux tetrahedron. The shape is mathematically interesting and draws you in. It is like a tetraminx with centre pieces. Or, if you prefer, a pyraminx with the corners snipped and centres added. It looks nice and turns beautifully. It's a little on the large size - but that makes sense when you look into how you construct the shape.
You solve this puzzle like a standard pyraminx. At that point you either have the centres in the correct places or not. You'll be one algorithm away from done...
