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.

These puzzles are made by bonding additional cubies to an existing puzzle. They therefore do not add to the complexity of the puzzle configuration, they just make it look more complex. Solution strategies remain the same, though a scrambled puzzle can have a strange appearance. 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.

Rubik’s Cubes have shaped the way we think about problems in life, and have demonstrated that most problems and puzzles don’t always have the simplest solution, but they are always solvable. The original Rubik’s Cube received a lot of attention and fame in the 1980s, which led to a mass developed 4x4x4 being marketed under the names Master Cube and Rubik’s Revenge. This eventually led to the Rubik’s Professor 5x5x5 cube, but puzzle designers already had everything they needed to take the twisty puzzle world to a new level – Cuboids. 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. 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.

Some designers have even gone as far as making 2x2x13 cuboids, but no higher than the 2x2x6 has been mass produced yet. aka: Slim Tower)". TwistyPuzzles.com. Archived from the original on 2016-03-03 . Retrieved 2009-06-12. Similar to the Gear Cube but on one axis there are no gears allowing for 3x3x3 turns on the top and bottom layer. Significantly harder than a Gear cube. The Rubik’s cube, although seemingly simple, is a complex mathematical puzzle. It is often used to teach fractions, proportions, and permutation & combination to students. Twisting and turning the cube yields unlimited combinations. In fact, established studies show that there are 43 quintillion possible combinations of the cube. 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.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. A Rubik’s cube of 4x4x4 amalgamation is called the Master Cube. Some also call it the Rubik’s Revenge. This Master Cube approximately has 7.4 quattuordecillion combinations. The numerical representation looks like this:

A Rubik’s cube of 4x4x4 amalgamation is called the Master Cube. Some also call it the Rubik’s Revenge. This Master Cube approximately has 7.4 quattuordecillion combinations. The numerical representation looks like this: 3. 4x4x4 Rubik’s cube 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 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 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 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. 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.
