The Void cube is a puzzle based on the 3x3x3 cube. It features a different mechanism that makes the puzzle entirely hollow. Unlike the normal 3x3x3 cube, it does not feature centers. It can be solved like a normal cube, except that the absence of centers allows for two corners or two centers to be swapped with the rest of the cube solved, which is not possible on the normal cube. This situation can be resolved by doing a 90 degree E slice move, taking out the middle layer edges, putting them into their correct spots, and then solving the last layer.
