The Rubik's Cube is a puzzle invented by Hungarian professor Ernő Rubik in 1974. In a Rubik's Cube, there are six faces and each of the six faces is covered by nine stickers, each one of six colors. The six colors are red, blue, white, yellow, orange, and green. In current models sold, green is opposite to blue, red is opposite to orange, yellow is opposite to white.
The internal mechanism in the cube enables each face to turn independently, so it causes it to mix the colors. For the puzzle to be solved, each face must be returned to have only one color. There are methods in solving the Rubik's Cube. One of methods, which is the simplest, is the Beginner's Method. Another is the CFOP Method or sometimes called the Fridrich method, which is the one of the most commonly used methods in speedsolving a Rubik's Cube.
