What is "speedcubing"

n. The activity of solving a Rubik's Cube as fast as possible vb. (present participle of speedcube English)

Speedcubing (also known as speedsolving) is the activity of solving a variety of twisty puzzles, the most famous being the Rubik's Cube, as quickly as possible. For most puzzles, solving entails performing a series of moves that alters a scrambled puzzle into a state in which every face of the puzzle is a single, solid color. Some puzzles have different requirements to be considered solved, such as the Clock, for which all the dials must be moved into the 12 'o clock position.

Most cubes are sold commercially in variations of 2×2×2, 3×3×3, 4×4×4, 5×5×5, 6×6×6, and 7×7×7, although variations of the puzzle have been designed with as many as 22 layers. The current world record for a single solve of the 3×3×3 in competition is 4.90 seconds, set by Lucas Etter in November 2015 at the River Hill Fall 2015 competition, and the world record average of five solves is 6.45 seconds, set by Feliks Zemdegs in July 2016 at the WLS Lato 2016 competition.

Speedcubing is a popular activity among the international Rubik's Cube community, or cubers. Members come together to hold competitions, work to develop new solving methods, and seek to perfect their technique. As a part of the community, puzzle builders and modders try to invent new forms of combination puzzles.
