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.
God's algorithm is a notion originating in discussions of ways to solve the Rubik's Cube puzzle, [1] but which can also be applied to other combinatorial puzzles and mathematical games. [2] It refers to any algorithm which produces a solution having the fewest possible moves (i.e., the solver should not require any more than this number).
The cube restricted to only the corners, not looking at the edges; The cube restricted to only 6 edges, not looking at the corners nor at the other edges. The cube restricted to the other 6 edges. Clearly the number of moves required to solve any of these subproblems is a lower bound for the number of moves needed to solve the entire cube.
A combination puzzle collection A disassembled modern Rubik's 3x3. A combination puzzle, also known as a sequential move puzzle, is a puzzle which consists of a set of pieces which can be manipulated into different combinations by a group of operations.
For the standard cube the marked cube value needs to be divided by (4!) 6 /2 (the 2 divisor must also be applied here). That gives an overall S value for the size 4 cube of 24!/(4!) 6. All states for 24-centre-cubie orbits for standard Rubik’s family cubes are reachable (if required, even parity is always achievable by swapping the positions ...
The book was published June 1981. [2] It became the best-selling book of 1981, selling 6,680,000 copies that year. [1] It was the fastest-selling title in the 36-year history of Bantam Books. [1] In November 1981 Nourse published a sequel, The Simple Solutions to Cubic Puzzles, as an aid to the numerous puzzles that were spawned by the Cube ...

Puzzles have been built resembling Rubik's Cube, or based on its inner workings. For example, a cuboid is a puzzle based on Rubik's Cube, but with different functional dimensions, such as 2×2×4, 2×3×4, and 3×3×5. [116] Other Rubik's Cube modifications include "shape mods", cubes that have been extended or truncated to form a new shape.
