A solved Rubik's 360 puzzle. Rubik's 360 is a 3D mechanical puzzle released in 2009 by Ernő Rubik, the inventor of Rubik's Cube and other puzzles. [1] Rubik's 360 was introduced on February 5, 2009 at the Nürnberg International Toy Fair [2] ahead of its worldwide release in August.
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 ...
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.
The Sudoku Cube or Sudokube is a variation on a Rubik's Cube in which the aim is to solve one or more Sudoku puzzles on the sides or rows. The toy was originally created in 2006 by Jay Horowitz in Sebring , Ohio . [ 11 ]
The Gear Cube is a 3-D combination puzzle designed and created by Dutch puzzle maker Oskar van Deventer based on an idea by Bram Cohen. [1] It was initially produced by Shapeways in 2009 and known as " Caution Cube " due to the likelihood of getting one's fingers stuck between the gears while speedcubing . [ 2 ]
As in many mathematical puzzles, finding a solution is made easier by solving a slightly more general problem: how to move a tower of h (height) disks from a starting peg f = A (from) onto a destination peg t = C (to), B being the remaining third peg and assuming t ≠ f.
Hoffman's packing puzzle is an assembly puzzle named after Dean G. Hoffman, who described it in 1978. [1] The puzzle consists of 27 identical rectangular cuboids, each of whose edges have three different lengths. Its goal is to assemble them all to fit within a cube whose edge length is the sum of the three lengths. [2] [3]
