Speedcubers are individuals who solve Rubik's Cubes and other twisty puzzles as quickly as possible. They use various techniques and algorithms to improve their solving times, often competing in events organized by the World Cube Association. These competitions feature different categories based on cube types and solving methods. Speedcubers often practice extensively, using timers and video analysis to refine their skills. The fastest solvers can complete a standard 3x3 Rubik's Cube in under six seconds, showcasing remarkable dexterity and mental agility.
