The four shown here are only a sample from a very large number of examples. Additional cubie pieces are then added, either modified from standard puzzles or made from scratch. Most of them start with the internal mechanism of a standard puzzle. Most of the puzzles in this class of puzzle are generally custom made in small numbers. There are many other sizes of virtual cuboid puzzles ranging from the trivial 3×3 to the 5-dimensional 7×7×7×7×7 which has only been solved twice so far. Significantly more difficult to solve than the standard cube, although the techniques follow much the same principles. However, it can be drawn or represented by a computer.
This is the 4-dimensional analog of a cube and thus cannot actually be constructed.
Main article: N-dimensional sequential move puzzles Pieces are often referred to as "cubies". A regular cuboid, in the context of this article, is a cuboid puzzle where all the pieces are the same size in edge length. Or in other words (in the majority of cases), a box shape. That is, all its edges form right angles. As well as cubes, all of the regular polyhedra and many of the semi-regular and stellated polyhedra have been made.Ī cuboid is a rectilinear polyhedron. There have been many different shapes of Rubik type puzzles constructed. An example is the 4-dimensional 3×3×3×3 tesseract puzzle, simulated by the MagicCube4D software. In fact, there are some puzzles that can only be realized in virtual space. The puzzle can be realized entirely in virtual space or as a set of mathematical statements. It is only necessary that the rules for the operations are defined. Since neither unpeeling the stickers nor disassembling the cube is an allowed operation, the possible operations of rotating various faces limit what can be achieved.Īlthough a mechanical realization of the puzzle is usual, it is not actually necessary. Similarly, not all the combinations that are mechanically possible from a disassembled cube are possible by manipulation of the puzzle. For instance, in the case of the Rubik's Cube, there are a large number of combinations that can be achieved by randomly placing the coloured stickers on the cube, but not all of these can be achieved by manipulating the cube rotations. This leads to some limitations on what combinations are possible. The mechanical construction of the puzzle will usually define the rules by which the combination of pieces can be altered. They are often face-turning, but commonly exist in corner-turning and edge-turning varieties. Puzzles like the Rubik's Cube which are manipulated by rotating a section of pieces are popularly called twisty puzzles. In the unsolved condition colours are distributed amongst the pieces of the cube. Each of the six faces is a different colour, but each of the nine pieces on a face is identical in colour, in the solved condition.
The most famous of these puzzles is the original Rubik's Cube, a cubic puzzle in which each of the six faces can be independently rotated. Often, the solution is required to be some recognisable pattern such as "all like colours together" or "all numbers in order". A combination puzzle is solved by achieving a particular combination starting from a random (scrambled) combination.
