Rubik’s Cube Solved in 7.85 seconds.
Rubik’s Cube is a mechanical puzzle invented in 1974 by the Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the “Magic Cube” by its inventor, this puzzle was renamed “Rubik’s Cube” by Ideal Toys in 1980 and also won the 1980 German “Game of the Year” (Spiel des Jahres) special award for Best Puzzle. It is said to be the world’s best-selling toy, with some 300,000,000 Rubik’s Cubes and imitations sold worldwide.
Typically, the faces of the cube are covered by 9 stickers in 6 solid colors; there is one color for each side of the cube. When the puzzle is solved, each face of the cube is a solid color. The cube celebrated its twenty-fifth anniversary in 2005, when a special edition cube in a presentation box was released, featuring a sticker in the center of the reflective face (which replaced the white face) with a “Rubik’s Cube 1980-2005” logo.
Many general solutions for the Rubik’s Cube have been discovered independently. The most popular method was developed by David Singmaster and published in the book Notes on Rubik’s Magic Cube in 1980. This solution involves solving the Cube layer by layer, in which one layer, designated the top, is solved first, followed by the middle layer, and then the final and bottom layer. After practice, solving the Cube layer by layer can be done in under one minute. Other general solutions include “corners first” methods or combinations of several other methods.
