The Holey Octahedron extends the family of hollow puzzles succeeding the Holey Megaminx (Tutt), Void Skewb (Fisher) and Void Cube (Okamoto). It is a variation on the standard 3x3x3 cube. It differs from the 3x3x3 in that the corners have completely been removed and center orientation is visible. Solving it is a little bit easier than a regular 3x3x3.
