Rubik’s Cube 3x3x3 solved in ~20 secs

So I was browsing on YouTube just to discover a video of a friend who solved a Rubik’s Cube (3x3x3) in less than 20 seconds – I didn’t even solve my cube so far. I guess I better go and find my Rubik’s cube and give it another shot…

If you have no clue about what a Rubik’s Cube is, let me try to explain it.

Official Rubik’s Cube 3×3x3

Wikipedia defines a Rubik’s Cube as followed:

Rubik’s Cube (commonly misspelled rubix, rubick’s or rubics 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.

A Rubik’s Cube has nine square facelets on each side, giving fifty-four facelets 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 colours; there is one colour for each side of the cube. When the puzzle is solved, each face of the cube is a solid colour. 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 centre of the reflective face (which replaced the white face) with a „Rubik’s Cube 1980-2005“ logo.[…]

Wikipedia gives more details about the cube, however, I just give you some common information 🙂

My friend, Martin K. aka JediKJ, was so kind and put together some trivia about the cube:

  • A normal (3×3×3) Rubik’s Cube can have (8! × 38−1) × (12! × 212−1)/2 = 43,252,003,274,489,856,000 different positions
  • if every permutation of a Rubik’s Cube was lined up end to end, it would stretch out approximately 261 light years.
  • Daniel Kunkle and Gene Cooperman used computer search methods to demonstrate that any 3x3x3 Rubik’s Cube configuration can be solved in a maximum of 26 moves
  • In March 1970, Harry D. Nichols invented a 2x2x2 „Puzzle with Pieces Rotatable in Groups“ and filed a U.S. patent application for it. Nichols‘ cube was held together with magnets. Nichols was granted U.S. Patent 3,655,201 on April 11, 1972, two years before Rubik invented his improved cube.
  • Over one hundred million Rubik’s Cubes were sold in the period from 1980 to 1982.
  • In 1994, Melinda Green, Don Hatch, and Jay Berkenilt created a model of a 3×3×3×3 four-dimensional analogue of a Rubik’s Cube called the MagicCube4D. Having more possible states than there are atoms in the known universe, only 55 people have solved it as of January 2007
  • In 2006, Roice Nelson and Charlie Nevill created a 3×3×3×3×3 five-dimensional model. As of January 2007, it has been solved by only 7 people.

Now after I talked so much, let me show you the YouTube video:

If you are longing for more information about the Rubik’s Cube, I recommend you visit the homepage of my friend at „zrrbite.dk – On Cubing„.

I still didn’t find my cube after finishing this article, so I need to keep on searching for it and can’t brag that I just solved it while typing this article 😉

Last but not least…Do you have a Rubik’s Cube? If so, did you solve it? Or do you have something else you want to say about this addictive toy?
