Revision as of 06:04, 4 September 2004 by Blonkm (talk | contribs)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)Speedcubing 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.
2x2x2 - Rubik's MiniCube
3x3x3 - Rubik's Cube
4x4x4 - Rubik's Revenge
5x5x5 - Rubik's Professor Cube
Here are some definitions generally used by the community. This community was started by Chris Hardwick. See also Ron van Bruchem's website, which holds the unofficial world records.
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 cubies
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 caroussel 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 10.15 seconds)
