![]() ![]() An early mathematical analyst of the cube, Morwen Thistlethwaite, was able to prove that any cube could be solved in at most 52 moves.Ĭomputer programmer Tomas Rokicki came up with a strategy for finding relatively short solutions for Rubik's Cube configurations. Over the decades, various upper bounds were proven. ![]() The remaining question, then, is whether or not there are any cubes that need more than 20 steps to solve. That sets a lower limit on what God's Number could be. In 1995, mathematician Michael Reid found a Rubik's Cube configuration called a "superflip" and proved that it required at least 20 moves to solve. ![]() The key to answering a question like finding the smallest number of moves to solve any configuration is to take advantage of the relationships between different configurations. Going through and trying to find the shortest solution for every single one of those configurations, then, is essentially impossible. An analysis of all the possible permutations of where the smaller constituent cubes (often called "cubies") can end up shows that there are about 43 quintillion - 43,000,000,000,000,000,000 - possible configurations of the Rubik's Cube. One reason it took so long to answer such an apparently straightforward question is the surprising complexity of the Rubik's Cube. In 2010, a group of mathematicians and computer programmers proved that any Rubik's Cube can be solved in, at most, 20 moves. One immediate and obvious question, dating back to the original invention of the cube, is, given a particular configuration of a cube, what's the smallest number of moves needed to solve the puzzle? Relatedly, what is the smallest number of moves needed to solve any configuration of the Rubik's Cube, a number that cube aficionados refer to as "God's number?"Īs Erno Rubik put it in a recent interview with Business Insider, this question is "connected with the mathematical problems of the cube."Īmazingly, it took 36 years after the invention of the toy to come up with an answer. The attempt happened on the set of the iDream of China TV Show in Hangzhou, Zhejiang, China, on 23 December.Account icon An icon in the shape of a person's head and shoulders. 2017 – This record was first set five years ago in China by Que Jianyu with a time of 5 min 6.61 sec.This record, incorporating both juggling and puzzle solving, has been hotly contested over the last few years, with cubers keen to show off their multitasking skills. What is the limit to how fast a human can solve a Rubik’s cube? It adds another layer of difficulty to the traditional puzzle solve. The record for the fastest time to solve three rotating puzzle cubes whilst juggling requires focus, dexterity and memory - while working against the clock. Fastest time to solve a rotating puzzle cube (3x3x3) by a team of two under water (18.93 sec, with Ye Jiaxi). ![]() Fastest time to solve a rotating puzzle cube (3x3x3) by a team of two (12.59 sec, with Ye Jiaxi).Most rotating puzzle cubes solved using one hand while suspended upside down (104).Most rotating puzzle cubes solved whilst suspended upside down (195).He has broken records solving the puzzles while upside down, with one hand and even underwater! Advertisements It also isn’t the first time he has solved rotating puzzle cubes while doing other things. Li Zhihao is a rotating puzzle cube enthusiast and holds various other Guinness World Records titles related to cubing. ![]()
