An original Rubik's Cube from 1980 in Hungary. The Rubik's Cube was invented on May 19, 1974, by Hungarian professor of architecture Ernő Rubik (born July 13, 1944). In 1979, Rubik partnered with Ideal Toy Company to garner widespread international interest in the cube. On June 5, 1982, the first world championship of speedcubing was held in ...
In 1999, the first modern age speedcubers found each other on the Internet via Rubik's Games, a computer game with an electronic version of the Rubik's Cube. Chris Hardwick from Raleigh, NC founded the Yahoo! Group "Speedsolvingrubikscube" and the Unofficial World Records, a place where cubers could post their personal best times.
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.
The popularity of the Cube is reflected in its strong sales—in 2022, 5.75 million units of the official Rubik’s Cube were sold globally and that figure was up 14% year-to-date, according to ...

[1] Ideal Toys agreed that Pentangle could sell what it now renamed as "Rubik's Cube" in the UK as a gift, but not as ...
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.

A cube is solvable if the set state has existed some time in the past and if no tampering of the cube has occurred (e.g. by rearrangement of stickers on hardware cubes or by doing the equivalent on software cubes). Rules for the standard size 3 Rubik's cube [3] [4] and for the complete Rubik's cube family [5] have been documented. Those rules ...
