Retirado de Wikipedia, the free encyclopedia
"O cubo de Rubik, também conhecido como cubo mágico, é um quebra-cabeça tridimensional, inventado pelo húngaro Ernő Rubik em 1974. Originalmente foi chamado o "cubo Mágico" pelo seu inventor, mas o nome foi alterado pela empresa redendedora para "cubo de Rubik". Nesse mesmo ano, ganhou o prémio alemão do "Jogo do Ano" (Spiel des Jahres). Ernő Rubik demorou um mês para resolver o cubo pela primeira vez. O cubo de Rubik tornou-se um ícone da década de 1980, década em que foi mais difundido.
O cubo de Rubik é um cubo geralmente confecionado em plástico e possui várias versões, sendo a versão 3x3x3 a mais comum, composta por 6 faces de 6 cores diferentes, com arestas de aproximadamente 5,5 cm. Outras versões menos conhecidas são a 2x2x2, 4x4x4 e a 5x5x5.
É considerado um dos brinquedos mais populares do mundo, atingindo um total de 900 milhões de unidades vendidas, bem como suas diferentes imitações."

[EN] Rubik's Cube
From Wikipedia, the free encyclopedia
"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 a toy manufacturer in 1980 via businessman Tibor Laczi and Seven Towns founder Tom Kremer, and won the German Game of the Year special award for Best Puzzle that year. 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.
In a classic Rubik's Cube, each of the six faces is covered by nine stickers, each of one of six solid colours: white, red, blue, orange, green, and yellow. 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 colours 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 consisting of 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 other twisty puzzles and compete for the fastest times in various categories. Since 2003, The World Cube Association, the Rubik's Cube's international governing body, has organized competitions and kept the official world records."
