Speedcubing - Definition

               Speedcubing (also known as speedsolving, or speed-cubing) is the activity of solving a Rubik's Cube or related puzzle as quickly as possible. Here, solving is defined as performing a series of moves that transforms a scrambled cube into a state where each of the cube's six faces is one single, solid color.

              Regular 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. Variations of the puzzle have been designed with as many as 17 layers, but the largest denomination cube that has been patented is a 7x7x7. The current world record for a single solve of the 3×3×3 in competition is 6.24 seconds set by Feliks Zemdegs during the Kubaroo Open 2011. However, unofficial "faster" times have been recorded on video.

          Speedcubing is a popular activity among the international Rubik's Cube community. 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 try to invent new forms of permutation puzzles.
