Non-human solving: The fastest non-human Rubik's Cube solve was performed by Rubik's Contraption, a robot made by Ben Katz and Jared Di Carlo. A YouTube video shows a 0.38-second solving time using a Nucleo with the min2phase algorithm. [98] Highest order physical n×n×n cube solving: Jeremy Smith solved a 21x21x21 in 95 minutes and 55.52 seconds.
All games have a Challenge and free play mode. Rubik's Classics: The main puzzle, 3x3, was composed of a standard Rubik's Cube, where the player could play and solve the puzzle using the PC's mouse, and even a paint and solve feature where they could paint the sides of the cube and the computer would find the quickest solution to that arrangement of the puzzle.
On a crazy cube type I, they are internally connected in such a way that they essentially move as 8 distinct pieces, not 24. To solve such a cube, think of it as a 2x2x2 (pocket cube) trapped inside a 4x4x4 (Rubik's Revenge). Solve the 2x2x2 first, then solve the 4x4x4 by making exchanges only. Solving the type II is much more difficult.
A scrambled Rubik's Cube. An algorithm to determine the minimum number of moves to solve Rubik's Cube was published in 1997 by Richard Korf. [10] While it had been known since 1995 that 20 was a lower bound on the number of moves for the solution in the worst case, Tom Rokicki proved in 2010 that no configuration requires more than 20 moves.

The maximal number of face turns needed to solve any instance of the Rubik's Cube is 20, [2] and the maximal number of quarter turns is 26. [3] These numbers are also the diameters of the corresponding Cayley graphs of the Rubik's Cube group. In STM (slice turn metric), the minimal number of turns is unknown.
Missing Link puzzle. Missing Link is a mechanical puzzle invented in 1981 by Steven P. Hanson and Jeffrey D. Breslow.. The puzzle has four sides, each depicting a chain of a different color.
Rubik's Puzzle World features multiple game modes, which capitalize on the Wii and Nintendo DS' pointer-based motion controls and differ across the two platforms: . Rubik's Cube: Players can learn how to solve any of three Rubik's Cubes of differing size, then use interactive controls to manipulate a virtual replica of one, racing against time to either solve it or reproduce as many ...
