History
The Rubik's Cube is a 3-D combination puzzle 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. The Rubik's Cube 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. It is widely considered to be the world's best-selling toy.
On the original classic Rubik's Cube, each of the six faces was covered by nine stickers, each of one of six solid colours: white, red, blue, orange, green, and yellow. Some current versions of the cube have been updated to use colored plastic panels instead, which prevents peeling and fading. In currently sold models, white is opposite yellow, blue is opposite green, and orange is opposite red, and the red, white, and blue are arranged in that order in a clockwise arrangement. On early cubes, the position of the colors varied from cube to cube. An internal pivot mechanism enables each face to turn independently, thus mixing up the colours. For the puzzle to be solved, each face must be returned to have only one colour. Similar puzzles have now been produced with various numbers of sides, dimensions, and stickers, not all of them by Rubik.
Although the Rubik's Cube reached its height of mainstream popularity in the 1980s, it is still widely known and used. Many Speedcubers continue to practice it and similar puzzles; they also compete for the fastest times in various categories. Since 2003, the World Cube Association, the Rubik's Cube's international governing body, has organised competitions worldwide and recognizes world records.
About the Cube
The 3x3 Rubik´s Cube has 20 pieces, 8 corners, 12 edges. Each side of the 3x3 Rubik's cube has 9 stickers each side.
There are 43,252,003,274,489,856,000 possible legal arrangement of a cube.
A god's number is 20 moves, you are always 20 moves away from the cube being solve or less.
Even though humans cannot figure out ideal 20 move maximum solutions all of the time, there are still other ways to solve the cube. CFOP is by far the most popular way to solve the cube, and is basically a speed solving oriented version of the Layer by Layer method, commonly called beginner's method.
The methods consist of several steps. The first is Cross where a cross is formed of for fully solved edges. After that, you solve the first layer corners, followed by the second layer edges. In CFOP, these 2 steps are combined into one. After the first two layers are solved, there are many ways to solve the last layer, some require as little as 3 algorithms, and others requiring as many as 4,000. You can find more information on all of this in the tutorials tab.
