The Skewb (/ ˈskjuːb /) is a combination puzzle and a mechanical puzzle similar to the Rubik's Cube. It was invented by Tony Durham and marketed by Uwe Mèffert. [1] Although it is cubical, it differs from the typical cubes ' construction; its axes of rotation pass through the corners of the cube, rather than the centers of the faces.
Cube mid-solve on the OLL step. The CFOP method (Cross – F2L – OLL – PLL), 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. This method was first developed in the early 1980s, combining ...
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. Given a random cube C, it is solved as iterative deepening. First all ...
Skewb Ultimate. The Skewb Ultimate, originally marketed as the Pyraminx Ball, is a twelve-sided puzzle derivation of the Skewb, produced by German toy-maker Uwe Mèffert. Most versions of this puzzle are sold with six different colors of stickers attached, with opposite sides of the puzzle having the same color; however, some early versions of ...
Speedcubing, also referred to as speedsolving, is a competitive mind sport centered around the rapid solving of various combination puzzles. The most prominent puzzle in this category is the N×N×N (n= 3) puzzle, commonly known as the Rubik's Cube. Participants in this sport are known as "speedcubers" (or more generally as "cubers"), who focus ...
v. t. e. 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. Many such puzzles are mechanical puzzles of polyhedral shape, consisting of ...
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. The allusion to the deity is based on the notion that an omniscient ...
Feliks Aleksanders Zemdegs [1] (/ ˈ f ɛ l ɪ k s ˈ z ɛ m d ɛ ɡ z /, Latvian: Fēlikss Zemdegs; born 20 December 1995) is an Australian Rubik's Cube speedsolver.He is one of the only two speedcubers ever to win the World Cube Association World Championship twice (the other being Max Park), winning in 2013 and 2015, and is widely considered the most successful and greatest speedcuber of ...
