A Rubik's Cube has nine square facets on each side, giving fifty-four facets in total, and occupies a volume of twenty-seven unit cubes. Typically, the faces of the cube are covered by nine stickers in six 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 orange face) with a "Rubik's Cube 1980-2005" logo.
The puzzle comes in four widely available versions: the 2×2×2 ("Pocket Cube"), the 3×3×3 standard cube, the 4×4×4 ("Rubik's Revenge"), and the 5×5×5 ("Professor's Cube").
Over one hundred million Rubik's Cubes were sold in the period from 1980 to 1982. It won the BATR Toy of the Year award in 1980 and again in 1981. Many similar puzzles were released shortly after the Rubik's Cube, both from Rubik himself and from other sources, including the Rubik's Revenge, a 4×4×4 version of the Rubik's Cube. There are also 2×2×2 and 5×5×5 Cubes (known as the Pocket Cube and the Professor's Cube, respectively) and puzzles in other shapes, such as the Pyraminx, a tetrahedron.
In 1981, Patrick Bossert, a twelve-year-old schoolboy from England, published his own solution in a book called You Can Do the Cube. The book sold over 1.5 million copies worldwide in seventeen editions.
At the height of the puzzle's popularity, separate sheets of colored stickers were sold so that frustrated or impatient Cube owners could restore their puzzle to its original appearance.
