High Quality Content by WIKIPEDIA articles! The Void Cube is a 3-D mechanical puzzle similar to a Rubik's Cube, with the notable difference being that the center "cubes" are missing, which causes the puzzle to resemble a level 1 Menger sponge. The central "spider" used on the Rubik's Cube is also absent, creating holes straight through the cube on all three axes. Due to the restricted volume of the puzzle it employs an entirely different structural mechanism from a regular Rubik's Cube. The Void Cube was invented by Katsuhiko Okamoto.The Void Cube is slightly more difficult than a regular Rubik's Cube due to parity.
