The MoYu 21 x 21 stickersless mega cube is the largest mass produced order NxN cube. It is a challenge for the best of the best cubers and turns incredibly well considering its size.

Before solving a rubix cube, it is important to understand how it works. A letter followed by a prime symbol means the face should turn clockwise, and vice versa.

Product Description

The Cube consists of six centre pieces that show one coloured face each, twelve edge pieces that show two coloured faces each, and eight corner pieces that show three coloured faces each. Each of the corner and edge pieces can move independently, swapping the positions of a pair of corners or edges. There are five hundred and ninety-two million possible combinations of these, but only twelve can form a solved cube.

There are a number of algorithms that can be used to transform the relative locations of pairs or sets of edge and corner pieces. These are generally applied in increments of one or more turns, and the result is that a cube can be repositioned to have its solved colours in any of a number of different ways.

There are now several large-scale twisty puzzles that have been inspired by the Rubik's Cube, including the tetrahedron (Pyraminx), the octahedron (Skewb Diamond), and the dodecahedron (Megaminx). They are generally less practical for competitive speedsolving than the smaller cubes because of their unwieldy size and mechanical problems such as "popping", where one or more centre pieces become dislodged from their correct position.

Product Features

The Rubik's Cube has a large number of possible permutations and is considered to be the best-selling puzzle of all time. In fact, there are now cubes available in sizes up to 10 x 11 x 11.

Erno Rubik is one of Hungary's most famous inventors and his Magic Cube is one of the most recognizable toys on the planet. It caused a global craze in the 1970's, selling millions of Cubes each year and cementing itself into popular culture.

In the solved state, the cube shows six central pieces with coloured faces and 12 edge pieces with two coloured sides. The colour combinations of these six pieces are fixed, but the relative positions of the edge and corner pieces can be altered by twisting the outer third of the cube.

The MoYu 21x21 cube is the biggest mass-produced mega cube in the world and challenges even the best of speedcubers. The internal mechanism is top quality and the cube turns incredibly smoothly.

The MoYu 21x21 cube is currently the largest mass-produced mega rubik's cube on the market. It is a great challenge for even the best cubers and will test your solving skills like never before!

A variety of different puzzles based on the Cube exist, including other sizes and shapes of cubes, tetrahedrons (Pyraminx), octahedrons (Skewb Diamond), and dodecahedrons (Megaminx). The Cube has also inspired a whole category of twisty puzzles in general.

Rubik's Cube is made of a combination of plastic and colored stickers, which denote the color and orientation of each face. The most important component is the plastic, which is made from acrylonitrile butadiene styrene (ABS) or nylon. [1] ABS and nylon are both thermoplastics, meaning they can be heated to their melting point, cooled, and reheated multiple times without significant degradation.

Both ABS and nylon require large amounts of energy to produce. In addition, shipping from the factory to stores uses additional energy. A notation system has been developed to make it easier to memorize sequences of moves. Singmaster notation is the most commonly used, with letters indicating faces and uppercase letter indicating layers, e.g. "Fb udl" means to turn the bottom layer clockwise, and "L" means to rotate the left inner layer.

Product Dimensions

Rubik's Cube is made up of 26 unique miniature cubes called "pieces" including a center shaft frame, 6 corner pieces, and 12 edge pieces. Each piece has a hidden inward extension that interlocks with the others. These extensions form a structure similar to a chuck on a mechanical arm, and they can be flexibly locked together if they are pulled.

This special design feature allows for the construction of a high-order mechanism with complex topology that has not been achieved by previous industrial mechanisms. The Rubik's Cube is a model for research on complex mechanisms with variable topology, which will eventually lead to new applications in the machinery industry.

The Rubik's Cube has a variety of other interesting features that make it an ideal model for scientific research. For example, it is a good example of combinatorics and group theory. This is because the rotation and cycle transposition of the cube can be represented by simple mathematical models.
