Speedcubing (also known as speedsolving) is the hobby involving solving a variety of combination or twisty puzzles, the most famous being the 3x3 puzzle or 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.^[1] The standard puzzle sizes are 2x2x, 3x3, 4x4, 5x5, 6x6, and 7x7. There are also different shapes of the famous puzzles, including Pyraminx, Megaminx, Skewb, and Square-1. An individual who competes in speedcubing is known as a speedcuber.
