# How to Solve the 21 by 21 Rubix Cube

18 July

The cube was invented by Erno Rubik, a Hungarian sculptor and professor. He built it as a way to understand how complex structures could have their parts moved independently without the entire mechanism falling apart.

The first step in solving the cube is to orient the edge pieces. There are several algorithms that you can use to do this.

## Size

There are a lot of people who have a passion for solving 21 by 21 Rubik cube, but few can break down the 33x33x33 puzzle. This cube has 6,153 moveable parts and weighs more than 22 times as much as a standard rubik’s cube.

This MoYu 21x21 stickerless super big cube represents the pinnacle of modern twisty puzzle design. It is the largest order NxN cube to be mass produced and will challenge even the best of solvers. It features large outer layers for more controllable turning and multi-inner-circle designs to add stablity and smoother turning.

Rubik’s cubes have been used to help people with autism develop hand-eye coordination and other motor skills. The cube’s popularity has increased as many people with disabilities find it relaxing and therapeutic.

## Colors

The colors of a rubik’s cube can be confusing. Fortunately, there are algorithms that can help you solve it quickly. Using these algorithms, you can make sure that all the edge pieces are properly aligned with their respective face colors.

A 21 by 21 rubik’s cube has 43 252 003 274 489 856 000 combinations, but with the right algorithm it can be solved easily. In fact, it is so easy to solve that some competitors have been able to break the world record with it.

The first step to solving the cube is to get all of the white cross foundations in place. This is done by matching the edge pieces on each lateral face with the center piece. Once this is complete, you can solve the rest of the cube.

## Weight

Unlike older official Rubik’s cubes, which have screws holding the center pieces in place, newer cubes use springs. This allows for a more compact mechanism and increased number of possible permutations. However, the new cubes are still very heavy, at least compared to their size.

There are many different variations of the puzzle, with some even shaped like Kepler-Poinsot polyhedra. Custom twisty puzzle designers are also pushing the limits of what is possible.

Park, who has autism, started solving Rubik’s Cubes as a kid. His parents say he loves the challenge and it’s good therapy for him. He has since become a top-ranked competitor and an official Rubik’s ambassador. His accomplishment was featured in the 2020 Netflix documentary, The Speed Cubers. He recently set a world record for the fastest time to solve a 21x21x21 cube.

## Material

Depending on the algorithm used, there are many different ways to solve the cube. For instance, one method involves memorizing a sequence of moves and applying them to the cube in order to achieve a desired result. Another method is to use Wolstenholme notation, which uses letters instead of numbers for each move.

The main material used for the Rubik’s cube is acrylonitrile butadiene styrene (ABS). This plastic is molded into pieces that are then fitted together to form the cube. This process requires a lot of heat, which creates a large amount of waste in the form of hot water and toxic fumes.

In addition to this, the stickers on the cube are made from polypropylene, which is also a waste product that can be toxic to human beings. Finally, the packaging used to transport the cubes from factory to store uses a lot of energy in the form of fossil fuels.

## Design

There are about 519 quintillion[53] possible arrangements of the cube's pieces, but only one in twelve is solvable. Solving the Cube requires memorising a sequence of moves that will cause a specific effect, such as swapping two corners or turning an edge. The specific effect depends on the algorithm used, and a number of different algorithms exist.

Some of these algorithms have side effects, such as permuting edges, which slow down the overall solve time. These are called 'permutation' algorithms and are employed early in the process when only a few sides remain to be solved.

A number of notations have been devised to make memorising these move sequences easier. The most widely used is Singmaster notation, which uses letters to denote the faces of the cube: Top (T), Bottom (B), Left (L), Right (R) and Front (F). A letter followed by a 2 indicates that the cube should be rotated twice around its axes.
