Professor's Cube the Eastsheen 5×5×5 and the V-Cube 5 are designed with different mechanisms in an attempt to remedy the fragility of the original design. There are 98 pieces on the exterior of the cube: 8 corners, 36 edges, and 54 centers (48 movable, 6 fixed). Any permutation of the corners is possible, including odd permutations, giving 8! possible arrangements. Seven of the corners can be independently rotated, and the orientation of the eighth depends on the other seven, giving 3 (or 2,187) combinations. There are 54 centers. Six of these (the center square of each face) are fixed in position. The
36 Cube mechanical puzzle that must be played on a manufactured grid. Therefore, it requires some abstract thinking, and a certain amount of special insight. The 36 Cube is, however, subtly different from the 36 officer problem. Careful inspection of the pieces reveals that two of the pieces are special. These two pieces will fit on certain parts of the base differently from other pieces of the same height. With this subtle modification, there are in fact 96 possible solutions to the 36 Cube puzzle. 36 Cube The 36 Cube is a three-dimensional sudoku puzzle created by ThinkFun. The puzzle consists of
