Minus Cube Cube is 12 times more difficult to solve. However, if one does not confine oneself to these two types of the Minus Cube, there are 48 Minus Cube variants which can be solved. Minus Cube The Minus Cube () is a 3D mechanical variant of the n-puzzle which was manufactured in the Soviet Union. It consists of a bonded transparent plastic box containing seven small cubes, each glued together from two U-shape parts: one white and one coloured. The length of one side of the interior of the box is slightly more than twice the length of the side of
Floppy Cube the Pocket Cube (with over 3.6 million combinations). As explained above, the total number of possible configurations of the Floppy Cube is 192, which is sufficiently small to allow a computer search for optimal solutions. The table below summarises the result of such a search, stating the number "p" of positions that require "n" twists to solve the puzzle: The above table shows that the puzzle is always at most 8 twists away from its solved state (i.e. its God's Number is 8). Similarly to the total number of combinations, this number is very low compared to the Rubik's Cube
