Rubik’s Cube Online is a 3-D combination puzzle game that can be played online. It was made in HTML5 technology and can therefore be played in the browser or with mobile devices. 

Rubik’s Cube invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, the puzzle was licensed by Rubik to be sold by Ideal Toy Corp. in 1980 via businessman Tibor Laczi and Seven Towns founder Tom Kremer. Rubik’s Cube Online won the 1980 German Game of the Year special award for Best Puzzle. As of January 2009, 350 million cubes had been sold worldwide, making it the world’s top-selling puzzle game.

Algorithms

In Rubik’s cubers’ parlance, a memorised sequence of moves that has a desired effect on the cube is called an algorithm. This terminology is derived from the mathematical use of algorithm, meaning a list of well-defined instructions for performing a task from a given initial state, through well-defined successive states, to a desired end-state. Each method of solving the Cube employs its own set of algorithms, together with descriptions of what effect the algorithm has, and when it can be used to bring the cube closer to being solved.

Many algorithms are designed to transform only a small part of the cube without interfering with other parts that have already been solved so that they can be applied repeatedly to different parts of the cube until the whole is solved. For example, there are well-known algorithms for cycling three corners without changing the rest of the puzzle or flipping the orientation of a pair of edges while leaving the others intact. Some algorithms do have a certain desired effect on the cube (for example, swapping two corners) but may also have the side-effect of changing other parts of the cube (such as permuting some edges).

Such algorithms are often simpler than the ones without side-effects and are employed early on in the solution when most of the puzzle has not yet been solved and the side-effects are not important. Most are long and difficult to memorise. Towards the end of the solution, the more specific (and usually more complicated) algorithms are used instead.

Rubik’s Cube solver program

The most move optimal online Rubik’s Cube solver programs use Herbert Kociemba’s Two-Phase Algorithm which can typically determine a solution of 20 moves or fewer. The user has to set the colour configuration of the scrambled cube, and the program returns the steps required to solve it.

Frequently Asked Questions (FAQs)

What is a Rubik’s cube?

Rubik’s Cube is a 3D mechanical puzzle with the shape of a cube. All sides are able to be rotated. Each side is divided into 9 squares. The goal is to get the colored squares aligned so that each side of the cube has a face of exactly one color. Its invented by Erno Rubik. You want to know how to solve it? We have tutorials how to solve it.

Who invented Rubik’s Cube?

It was the puzzle’s creator, an unassuming Hungarian architecture professor named Erno Rubik. When he invented the cube in 1974, he wasn’t sure it could ever be solved. Mathematicians later calculated that there are 43,252,003,274,489,856,000 ways to arrange the squares, but just one of those combinations is correct.
