The maximal number of face turns needed to solve any instance of the Rubik's Cube is 20, [2] and the maximal number of quarter turns is 26. [3] These numbers are also the diameters of the corresponding Cayley graphs of the Rubik's Cube group. In STM (slice turn metric), the minimal number of turns is unknown.
Mátyás Kuti is a Hungarian Rubik's Cube and Rubik's Magic solver. During 2007 and 2008 he held world records in many events. [1] However, in February 2008, after determining that he had cheated in blindfolded events by peeking at the cube, the World Cube Association revoked all of his blindfold records and banned him for three years from WCA competitions.

Solving a Rubik's cube in 10.48 seconds Tobias "Toby" Mao (born December 21, 1988) is a former world-class Rubik's Cube solver. Hailing from Hillsborough, California , Toby graduated from Crystal Springs Uplands School in 2007 and went on to study mathematics at Northwestern University in Evanston, Illinois .
A scrambled Rubik's Cube. An algorithm to determine the minimum number of moves to solve Rubik's Cube was published in 1997 by Richard Korf. [10] While it had been known since 1995 that 20 was a lower bound on the number of moves for the solution in the worst case, Tom Rokicki proved in 2010 that no configuration requires more than 20 moves.

Non-human solving: The fastest non-human Rubik's Cube solve was performed by Rubik's Contraption, a robot made by Ben Katz and Jared Di Carlo. A YouTube video shows a 0.38-second solving time using a Nucleo with the min2phase algorithm. [98] Highest order physical n×n×n cube solving: Jeremy Smith solved a 21x21x21 in 95 minutes and 55.52 seconds.
Cube mid-solve on the OLL step. The CFOP method (Cross – F2L (first 2 layers) – OLL (orientate last layer) – PLL (permutate last layer)), also known as the Fridrich method, is one of the most commonly used methods in speedsolving a 3×3×3 Rubik's Cube. It is one of the fastest methods with the other most notable ones being Roux and ZZ.
Yu Nakajima (中島 悠, born February 15, 1991 in Ebetsu, Hokkaidō) is a Japanese Rubik's Cube solver. [1] Yu held the former world record for Rubik's Cube average (11.28 seconds) and single (8.72 seconds). [2] He beat the previous world record holder Edouard Chambon, who had a single solve record of 9.18 seconds. [3]
