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". If that number seems incomprehensible, it sort of is. One quintillion has 18 zeroes, or 1,000,000,000,000,000,000. To put things in perspective, a quintillion is the same as a billion billions or a million trillions. Number of Possible Permutations

It does, however, have an interesting difference in its solution. The vertical corner columns are different colours to the faces and do not match the colours of the vertical face columns. The corner columns can therefore be placed in any corner. On the face of it, this makes the solution easier, however odd combinations of corner columns cannot be achieved by legal moves. The solver may unwittingly attempt an odd combination solution, but will not be aware of this until the last few pieces. 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. The world’s first fully functional cuboid transformation was Tony Fisher’s 3x3x4 puzzle, made from a Rubik’s Revenge. This was Tony Fisher’s first of currently 12 fully functional cuboid puzzles, however this one is the most ground-breaking due to its implications on the world of twisty puzzle design, including the methods used by Fisher to create the extra pieces needed to utilize a currently existing mechanism. Shapeshifting
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. aka: Slim Tower)".

One must be warned that most of these numbers are incomprehensible, and the terms that are used to describe them are mostly unknown to most people. Let us take a look at how many combinations each of these Rubik’s cube adaptations can boast: 1. Cube The 7x7x7x cube has 19.5 duoquinquagintillion combinations. A duoquinquagintillion can be represented as 10159 (10 to the power of 159), or 159 zeroes after the 1. The 7x7x7 Rubik’s cube is marketed under Verdes’ V-Cube brand, and has an exact combination of:This is the 4-dimensional analog of a cube and thus cannot actually be constructed. However, it can be drawn or represented by a computer. Significantly more difficult to solve than the standard cube, although the techniques follow much the same principles. 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. [1] However, the 6×6×6×6×6 has only been solved once, since its parity does not remain constant (due to not having proper center pieces) This change of mind return policy is in addition to, and does not affect your rights under the Australian Consumer Law including any rights you may have in respect of faulty items. 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.
First rotational puzzle created that has just one colour, [9] requiring the solver to restore the puzzle to its original cube form without colour aids. Panagiotis Verdes, a Greek inventor, is famous for inventing the 6x6x6 and the 7x7x7 cubes. The inventor used a special strategy to build these cubes, which were previously believed to be impossible. The 6x6x6 Rubik’s cube is marketed under the brand V-Cube, and the following possible combinations:
From the manufacturer
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. Most of the puzzles in this class of puzzle are generally custom made in small numbers. Most of them start with the internal mechanism of a standard puzzle. Additional cubie pieces are then added, either modified from standard puzzles or made from scratch. The four shown here are only a sample from a very large number of examples. Those with two or three different numbers of even or odd rows also have the ability to change their shape. The Tower Cube was manufactured by Chronos and distributed by Japanese company Gentosha Education; it is the third "Okamoto Cube" (invented by Katsuhiko Okamoto). It does not change form, and the top and bottom colours do not mix with the colours on the sides. A combination puzzle, also known as a sequential move puzzle, is a puzzle which consists of a set of pieces which can be manipulated into different combinations by a group of operations. Many such puzzles are mechanical puzzles of polyhedral shape, consisting of multiple layers of pieces along each axis which can rotate independently of each other. Collectively known as twisty puzzles, the archetype of this kind of puzzle is the Rubik's Cube. Each rotating side is usually marked with different colours, intended to be scrambled, then 'solved' by a sequence of moves that sort the facets by colour. As a generalisation, combination puzzles also include mathematically defined examples that have not been, or are impossible to, physically construct. They're based in convenient locations including supermarkets, newsagents and train stations. Plus they're often open late and on Sundays.
The final step is to solve the middle layer. This is also very simple. If you have two matching adjacent pieces, move the middle layer until they match the top and the bottom layer. Hold the cube horizontally and perform the following algorithm to swap the two “top” pieces (remember that because the cube is now rotated, an R2 move will be made using one of the 2x2 faces you made earlier): R2 U2 R2 U2 R2 U2 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. 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. A variation on the original Rubik's Cube where it can be turned in such a manner as to distort the cubical shape of the puzzle. The Square One consists of three layers. The upper and lower layers contain kite and triangular pieces. The middle layer contains two trapezoid pieces, which together may form an irregular hexagon or a square. Square One is an example of another very large class of puzzle— cuboid puzzles which have cubies that are not themselves all cuboid.The 3D Rubik’s Cube solver on Grubiks was developed so people would be able to solve the Rubik’s Cube without having to learn and memorize these methods. If you have an old scrambled cube just lying around the house, if you’re trying to learn how to solve it on your own and just need a “reset”, if you're looking for algorithms for patterns, or even if you just want to impress your friends - this solver is perfect for you. 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? However, over the years, many algorithms for solving the Rubik's Cube were developed, and today, learning how to solve the Rubik’s Cube is merely a task of following a series of steps and memorizing some algorithms.
