The 3×3 one-handed, in numbers
Everything countable about the 3×3 one-handed: the mathematics of the puzzle with its sources, and the live state of the sport, rebuilt nightly.
- A 3×3 has 43,252,003,274,489,856,000 positions (43.25 quintillion). Visiting one per second would take about 1.4 trillion years, roughly a hundred times the age of the universe. cube20.org
- God's Number is 20. God's Number answers a simple question: what is the worst case for a perfect solver? However scrambled the cube, a shortest possible solution never needs more than 20 moves. That was proven in 2010 by Rokicki, Kociemba, Davidson and Dethridge, using about 35 CPU-years of computing donated by Google. cube20.org
- One-handed solving uses the same puzzle and the same scrambles as the two-handed event; only the regulation differs: one hand, any hand, and the other may not touch the cube during the solve.
- The world record single is 5.62 by Patrick Ponce, standing 23 days.
- The world record average is 6.99 by Zhen Chen (陈震), standing 43 days.
- 2,367,464 completed solves are on the official record in 3×3 one-handed, from 11,006 competitions in 152 countries.
- 73,695 people hold an official ranking. The median personal best among all of them is 31.47.
- 779 people have ever gone under 10.00 seconds.
- The world record has moved 32 times since records began in 2003.
- 152 countries hold a national record, and the spread is wide: the fastest is 5.62, the most beatable 3:37.19.
- Today's one-handed world record (5.62) is faster than every two-handed world record set up to 2011: one hand now beats what two hands could do then.
- Results begin in 2003; every figure on this page recomputes nightly from the official export.
