Rubik's Cube being solved.

Speed cubing is the art of solving a Rubik's Cube as fast as possible. Solving here means to make the cube have each face be one single color. Regular cubes come in variations of 2x2x2, 3x3x3, 4x4x4, and 5x5x5. Puzzle builders try to invent new forms of permutation puzzles. Maybe the best way to learn what speedcubing actually is to watch a video. In the video on this page, Shotaro "Macky" Makisumi set the world record of 12.11 seconds.

History

The Rubik's cube was invented in 1974 by the Hungarian professor of architecture Ernö Rubik. The international interest in the cube began in 1980 to last until about 1983. On June 5, 1982 the first world championship was held in Budapest. After 1983 the interest faded away. With the advent of the internet, sites relating to speedcubing raised the profile of the art. Starting in 2003, regular national and international championships are being organized.

Cube variations

The different sized cubes are usually referred to as:

The cube can be solved using several methods, of which not all are suited for speedcubing. One of the most used speedcubing methods is the Fridrich method, named after Jessica Fridrich, who invented it, and also finished 2nd in the 2003 Rubiks Cube World Championships.

Competitions

Official competitions are currently being held in several categories:

Terminology

Here are some definitions generally used by the speed cubing community. This community was started by Chris Hardwick, the reigning one-handed-solving champion. The speedcubers communicate mostly via a Yahoo group and the speedcubing website.

Move
A turn or double turn of one of the six colored sides
Algorithm
Predefined sequence of moves
F2L
First Two Layers
F2L Method
a method which does First and Second layer in 1 step
LL
Last Layer
X Look
number of algorithms needed for the last layer, e.g. 4 Look
Prime
A counter clock wise move, e.g. R Prime (or R-, R', R-1)
Method
Combination of algorithms that can be used to solve a cube
Piece
One of the 20 detachable little cubes
Edge piece
One of the 12 edges
Corner piece
One of the 8 corners
Center
One of the six centers of the faces of the cube. The centers never move relative to each other.
Orient
Flip or twist pieces so they turn 'in-place'
Permute
Swap or carousel 2 or more pieces
OLL
Orient last layer
PLL
Permute last layer
PB
Personal best (time to solve a cube)
WR
World Record (currently 12.11 seconds)
UWR
Unofficial World Record (currently 9.54 seconds)
