Void Cube

The Void Cube was invented by Katsuhiko Okamoto and Gentosha Education (Japan), holds the license to manufacture. This puzzle is just like the 3x3x3 Rubik’s Cube, but it has no centerpieces just holes. You can look through it. The typical center core of the Magic Cube is missing. Because of its mechanism it doesn’t move so smooth like a normal Rubik’s Cube and it doesn’t cut corners so well but it’s still a nice puzzle. If you want to try how it works you can easily simulate it by pealing off the stickers from every center piece on a Rubik’s Cube.

Parity

The Void Cube is a little bit more complicated than the Rubik’s Cube despite it has the same number of possible permutation. It is more difficult because you don’t see the color of the centerpieces, which determines the color of each face, so you have to check the corners to find the color scheme. And if you solve one face around the wrong centerpiece you can find yourself in a parity. In this case you can rebuild the pieces around an other imaginary centerpiece or you can cheat by applying an algorithm.

For the Void Cube solution first you have to understand the notation and the solution of the Rubik’s Cube, and when you know this you have to apply the same solution and the parity algorithms as a final step if necessary. If you don’t understand what the letters mean first learn the Rubik’s notation. In case of parity use the following algorithm, even if you have a corner or edge parity, this relocates the centers, and after that solve the last layer again as normal.

Other holey twisty puzzles

The Void Cube was just the beginning of making holey 3D mechanical twisty puzzles. Indisputable this is the most basic and famous version but we have to mention here the Holey Megaminx, Holey Skewb, but there is Void 6x6x6 with a 2×2 hole and the list goes on.
