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 ...
Nineteen people competed in the event, and the American Minh Thai won with a single solve time of 22.95 seconds, which was, at the time, the fastest Rubik's Cube solve ever recorded. Other attendees include Jessica Fridrich and Lars Petrus , both of whom later contributed to the development of new solving methods and the speedcubing community ...
In 1982, David Singmaster and Alexander Frey hypothesised that the number of moves needed to solve the Cube, given an ideal algorithm, might be in "the low twenties". [61] In 2007, Daniel Kunkle and Gene Cooperman used computer search methods to demonstrate that any 3×3×3 Rubik's Cube configuration can be solved in 26 moves or fewer.
A six-year-old girl from China has set a new women’s world record for solving the 3x3x3 Rubik’s Cube in 5.97 seconds. Cao Qixian, of China’s Jiangsu Province, achieved the feat at the Rubik ...

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 ...
Valk has also set three 4x4x4 world records, two for single solve and one for an average of 5. His second single world record, 26.77 seconds on 15 April 2012, was the first official 4x4x4 solve under 30 seconds. Altogether, Valk has broken 5 WCA world records, 17 European records, and 127 Dutch national records. Valk also currently holds the ...
