Still needs a closing. Don't flame me, I'm just sharing my work.

The Rubik's cube is a 3-dimensional puzzle invented by Hungarian professor and sculptor Ernő Rubik. It has 6 independently turning sides, each with there own face color stickers. The main premise of the puzzle is to get one solid face on each side. Its simple design, yet extremely complex challenge made it one of the biggest selling puzzle game in history. There also many variations to the standard 3x3x3 Rubik's cube, such as the 4x4x4, 5x5x5, 2x2x2, and Square 1 just to name a few.
The Rubik's cube was a product of necessity. During the mid-seventies, Ernő Rubik sought to find a better way for his students to understand 3-Dimensional objects. He officially invented and patented the “Magic Cube” in 1974. In 1977 the test models were sold at German toy shops. In 1979, the “Magic cube” was featured and was starting to be sold around Paris, New York, London, and Nuremberg. During It's final transition to the west, the company who owned the rights to produce the cube changed the name from “Magic Cube” to “Rubik's cube”.
The puzzle has a rather simple mechanism. 21 interlocking pieces called “cubies” surround a fixed, 6 axis core. This mechanism allows free rotation of each face. Them stickers of most cubes that can bought at stores today are laminate stickers that wear out ofer time, unlike the original stickers that were put on the 1980's versions. Also unlike the 1980's version, many changes to the cubies themselves have been changed. The centers of the 6 axis core have been rounded, and the pieces have been slightly rounded, to allow smoother movement. It has also been made lighter for safetey reasons. Those who are faster at solving will usually use whats called a “Diy cube”. The exact creator of diy cubes is unknown, but now there are many variations stemming from the original. Diy cubes have the same mechanism as original rubiks cubes, except tey use whats called a “screw spring structure”. Inside of the 6 axis core, are screws which can be adjusted to the users preference. These cubes cannot be bought in in stores, and must be online. The most notable shop for Diy cubes online is CubeForYou.com, wich carries almost all types of Diy puzzles.
Those who have mastered the puzzle, and strive to get faster are called speedsolvers. Speedsolving is defined by those who do it as “Anyone who tries to solve the puzzle as fast as they possibly can.”. The community of speedsolvers is incredibly large, and world wide. Competitions are held all around the world to see who can get the fastest time on the puzzle they are solving. Currently, the fastest official time for solving a 3x3 rubiks cube is 7.08 seconds, set by Erik Akkersijk. All official competitions are goverened by the World Cubing Association. The WCA keeps record of all participants in any official competion. The WCA also governs how puzzles are scrambled, wether or not the solve is legitimate, etc.
There are many methods for solving the Rubik;s cube. The most well known is the one taught by the book “You can do the cube”, called LBL. This method solves all of the bottom edge stickers. Then it solves the entire bottom side. Next it uses simple algorithms to sovle the middle layer, and uses other algorithms to solve the top layer. Another popular method is one created by Jessica Fridrich, called the Fridrich method, or CFOP. This method combines the second and third step of the LBL method, and also combines the last step into only 2 algorithms. This method as used to set the world record, and is highly regarded as one of the fastest methods. Other notable methods such as Petrus (created by Lars Petrus) and the Roux method (created by Gilles Roux) are also very fast, and are used by speedcubers today.
