Although a mechanical realization of the puzzle is usual, it is not actually necessary. It is only necessary that the rules for the operations are defined. The puzzle can be realized entirely in virtual space or as a set of mathematical statements. In fact, there are some puzzles that can only be realized in virtual space. An example is the 4-dimensional 3×3×3×3 tesseract puzzle, simulated by the MagicCube4D software.
Mechanically identical to the standard 3×3×3 cube. However, the numbers on the centre pieces force the solver to become aware that each one can be in one of four orientations, thus hugely increasing the total number of combinations. The number of combinations of centre face orientations is 4 6. However, odd combinations (overall odd number of rotations) of the centre faces cannot be achieved with legal operations. The increase is therefore x2 11 over the original making the total approximately 10 24 combinations. This adds to the difficulty of the puzzle but not astronomically; only one or two additional algorithms are required to affect a solution. Note that the puzzle can be treated as a number magic square puzzle on each of the six faces with the magic constant being 15 in this case. The Tower Cube 2x2x3is a part of a series of 2x2xN cuboid puzzles. It is comprised of 8 corner pieces and 4 edge pieces. This small amount of moving parts results also in a relatively low number of possible combinations. According to our extensive computer simulations, this puzzle only has241,920 possible combinations - each ofwhichcan be solved in 14 moves or less. It is considered to be a rather easy puzzle to solve. aka: Slim Tower)". TwistyPuzzles.com. Archived from the original on 2016-03-03 . Retrieved 2009-06-12. Mechanically identical to the 3×3×3 cube although the example pictured is easier to solve due to the restricted colour scheme. This puzzle is a rhombicuboctahedron but not a uniform one as the edge pieces are oblong rather than square. There is in existence a similar puzzle actually called Rhombicuboctahedron which is uniform.Experimental cube made by 3-D printing of plastic invented by Oskar van Deventer. Corners are much larger in proportion, and edge pieces match that larger dimension; they are narrow, and do not resemble cubes. The rest of the cubelets are 15x15 arrays on each side of the whole cube; as planned, they would be only 4mm on a side. The original mechanism is a 3x3x3 core, with thin "vanes" for the center edges; the rest of the cubelets fill in the gaps. The core has a sphere at its center. As of 2023 it is being mass produced by the Chinese companies YuXin and Shengshou. [10] A cuboid is a rectilinear polyhedron. That is, all its edges form right angles. Or in other words (in the majority of cases), a box shape. A regular cuboid, in the context of this article, is a cuboid puzzle where all the pieces are the same size in edge length. Pieces are often referred to as "cubies". The 2x2x4 was, surprisingly, invented much earlier than the 2x2x3 cube. The puzzle was made by Tony Fisher, using a standard 4x4 “Rubik’s Revenge” puzzle, in the late 1990s. It is unknown whether or not Fisher was the first to build this puzzle, although he is credited as the inventor by many sources. The 2x2x4 can technically shapeshift, although due to its small size any shapeshifting that is performed can be easily undone without external algorithmic support for most puzzlers.
The original 2x2x6 was invented a full 6 years before its predecessor in the tower cube series. The first design used a standard 4x4 for its base, although this was heavily modified to create the new puzzle (in fact, for the first version, two 4x4s were used). The second 2x2x6 to be made was created by Tony Fisher, the first of its kind to use symmetrical pieces. This version was created in the years following the original release, which served as its inspiration. This puzzle has now been mass produced by WitEden, at the same time as the 2x2x5.There have been many different shapes of Rubik type puzzles constructed. As well as cubes, all of the regular polyhedra and many of the semi-regular and stellated polyhedra have been made.

The 2x2x7 cuboid was invented as a follow-up to the 2x2x6 by Tony Fisher. Despite its functioning state, the movement of the puzzle was fairly poor, and has been kept as a one-off design from Fisher ever since. Siamese cubes are two or more puzzles that are fused so that some pieces are common to both cubes. The picture here shows two 3×3×3 cubes that have been fused. The largest example known to exist is in The Puzzle Museum [8] and consists of three 5×5×5 cubes that are siamese fused 2×2×5 in two places. there is also a "2 3x3x3 fused 2x2x2" version called the fused cube. The first Siamese cube was made by Tony Fisher in 1981. [9] This has been credited as the first example of a "handmade modified rotational puzzle". [9] Since the time the original Rubik’s cube was launched, there have been many adaptations. Most of these adaptations come in different numbers of cubes within the actual cube. While the original one is 3x3x3, there are also cubes with 2x2x2, 4x4x4, and other amalgamations.

Mechanically identical to the standard 3×3×3 cube. The pattern, which is often a promotional logo or pictures of performers, will usually have the effect of making the orientation of the centre pieces 'count' in the solution. The solution is therefore the same as the 'Magic Square' cube above.Some designers have even gone as far as making 2x2x13 cuboids, but no higher than the 2x2x6 has been mass produced yet. Solutions to this cube is similar to a regular 3x3x3 except that odd-parity combinations are possible with this puzzle. This cube uses a special mechanism due to absence of a central core. They're based in convenient locations including supermarkets, newsagents and train stations. Plus they're often open late and on Sundays. The original 3x3x3 has many likely patterns. According to those who have figured it out, the exact count is 43 quintillion, 252 quadrillions, 3 trillion, 274 billion, 489 million, 856 thousand. To illustrate this, all the permutations and combinations of a large Rubik’s cube of 6 centimeters can cover the Earth’s surface 300 times. How many combinations are possible among Rubik’s cube adaptations? There are many puzzles which are mechanically identical to the regular cuboids listed above but have variations in the pattern and colour of design. Some of these are custom made in very small numbers, sometimes for promotional events. The ones listed in the table below are included because the pattern in some way affects the difficulty of the solution or is notable in some other way.
A Rubik’s cube of 5x5x5 is called the Professor’s Cube. It has an approximately 283 trevigintillion combinations. If you have never heard of this term, you probably are not alone. The exact number of combinations possible in this amalgamation is: Next, you can permute the top and bottom layers separately by locating two solved adjacent corners (they should both have the same colour on one side), putting them on the left of the cube and performing the algorithm: R2 U R2 U’ R2 F2 U’ F2 U F2. If you don’t have two solved adjacent corners, do the algorithm from any angle to get two. After this step, the top and bottom layers should be solved.A traditional sliding piece puzzle. There are now endless variations of this original puzzle implemented as computer games. The solution to the 2x2x4 is slightly different to that of its predecessor. This cube can shape-shift slightly, although the shapeshifting will always leave 1x1x2 bars together. To undo the shape-shifting, simply solve a single layer of the bars and complete the last layer like a 2x2 cube (because some of the pieces are bandaged, the puzzle will function just like a 2x2, except instead of every 1x1 cubie, you will have 1x1x2 bars). The 2x2x3 and 2x2x4 are the most common tower puzzles, so only these two will have their solutions explicitly explained. Most of the concepts of these cubes can be applied to larger 2x2xN puzzles, so once you can solve these two you should be able to solve them all. 2x2x3 Solution
