A randomly scrambled Rubik's Cube will most likely be optimally solvable in 18 moves (~ 67.0%), 17 moves (~ 26.7%), 19 moves (~ 3.4%) or 16 moves (~ 2.6%) in HTM. [4] By the same token, it is estimated that there is only 1 configuration which needs 20 moves to be solved optimally in almost 90×10 9 , or 90 billion, random scrambles.
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.
Jessica Fridrich (born Jiří Fridrich) is a professor at Binghamton University, who specializes in data hiding applications in digital imagery.She is also known for documenting and popularizing the CFOP method (sometimes referred to as the "Fridrich method"), one of the most commonly used methods for speedsolving the Rubik's Cube, also known as speedcubing.

However, draughts with only 5 × 10 20 positions [21] and even fewer, 3.9 × 10 13, in the database, [22] is a much easier problem to solve –of the same order as Rubik's cube. The magnitude of the set of positions of a puzzle does not entirely determine whether a God's algorithm is possible.
The Simple Solution to Rubik's Cube by James G. Nourse is a book that was published in 1981. The book explains how to solve the Rubik's Cube. The book became the best-selling book of 1981, selling 6,680,000 copies that year. It was the fastest-selling title in the 36-year history of Bantam Books.
The Rubik's Cube is constructed by labeling each of the 48 non-center facets with the integers 1 to 48. Each configuration of the cube can be represented as a permutation of the labels 1 to 48, depending on the position of each facet. Using this representation, the solved cube is the identity permutation which leaves the cube unchanged, while ...
The popularity of the Cube is reflected in its strong sales—in 2022, 5.75 million units of the official Rubik’s Cube were sold globally and that figure was up 14% year-to-date, according to ...
If a white-OC piece is on the bottom slice of the cube: If the white is on the D face, simply rotate D until the OC is directly underneath its center, and apply F² (assuming the piece is at the FD position) to put it in the correct location. If the OC is on the D face, hold the cube so white is the U center, and OC is the F center.
