    The first is to count the number of quarter turns. The second is to count the number of outer-layer twists, called "face turns". A move to turn an outer layer two quarter (90°) turns in the same direction would be counted as two moves in the quarter turn metric (QTM), but as one turn in the face metric (FTM, or HTM "Half Turn Metric").

    Cube layer A cube layer is a one-cubie-thick slice of the cube perpendicular to its axis of rotation. Outer layers (faces) contain more cubies than inner layers. For a cube of size , there will be layers along any given axis. Cube face The meaning of a cube face depends on the context in which it is used.

  4. Rubik's Revenge - Wikipedia

    en.wikipedia.org/wiki/Rubik's_Revenge

    A solved Rubik's Revenge cube. The Rubik's Revenge (also known as the 4×4×4 Rubik's Cube) is a 4×4×4 version of the Rubik's Cube.It was released in 1981. Invented by Péter Sebestény, the cube was nearly called the Sebestény Cube until a somewhat last-minute decision changed the puzzle's name to attract fans of the original Rubik's Cube. [1]

  5. Speedcubing - Wikipedia

    en.wikipedia.org/wiki/Speedcubing

    The CFOP method is used by the majority of cubers and employs a layer-by-layer system with numerous algorithms for solving the final layer. The method starts by creating a cross on any side of the cube, followed by F2L where 4 corner edge pairs are inserted into the cross, followed by OLL (Orientation of the Last Layer) where the top side is ...

    en.wikipedia.org/wiki/God's_algorithm

    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 book contained his own "step by step solution" for the Cube, [18] and it is accepted that he was a pioneer of the general Layer by Layer approach for solving the Cube. [19] The book also contained a catalogue of pretty patterns including his "cube in a cube in a cube" pattern which he had discovered himself "and was very pleased with". [20]

  8. CFOP method - Wikipedia

    en.wikipedia.org/wiki/CFOP_method

    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.

  9. The spider and the fly problem - Wikipedia

    en.wikipedia.org/wiki/The_spider_and_the_fly_problem

    A different lateral thinking solution, beyond the stated rules of the puzzle, involves the spider attaching dragline silk to the wall to lower itself to the floor, and crawling 30 feet across it and 1 foot up the opposite wall, giving a crawl distance of 31 feet. Similarly, it can climb to the ceiling, cross it, then attach the silk to lower ...
