A scrambled Rubik's Cube. Optimal solutions for the Rubik's Cube are solutions that are the shortest in some sense. There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. The second is to count the number of outer-layer twists, called "face turns".
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.

The Rubik's Cube world champion is 19 years old an can solve it in less than 6 seconds. While you won't get anywhere near his time without some years of practice, solving the cube is really not ...
The Rubik's Cube was inducted into the US National Toy Hall of Fame in 2014. [14] On the original, classic Rubik's Cube, each of the six faces was covered by nine stickers, with each face in one of six solid colours: white, red, blue, orange, green, and yellow. Some later versions of the cube have been updated to use coloured plastic panels ...
Over a span of years, Gilles Roux developed his own method to solve the 3x3x3 cube. Using a smaller quantity of memorized algorithms than most methods of solving, Roux still found his method to be fast and efficient. The first step of the Roux method is to form a 3×2×1 block. The 3×2×1 block is usually placed in the lower portion of the ...
First of all, hold the cube so that the "empty" edge piece is in the BR position, and thus the "empty" corner piece is in the RDB position. To do moves in this part, first of all move a piece into the BR location, then move it to the U face, to one of those UF, UL, or UB positions. The move is as follows. First, optionally rotate U.
A six-year-old girl from China has set a new women’s world record for solving the 3x3x3 Rubik’s Cube in 5.97 seconds. Cao Qixian, of China’s Jiangsu Province, achieved the feat at the Rubik ...
