The following are the current official speedcubing world records approved by the WCA. [4] Note: For averages of 5 solves, the best time and the worst time are dropped, and the mean of the remaining 3 solves is taken. For events where only 3 solves are done, the mean of all 3 is taken.
In 3×3×3 blindfolded and 3×3×3 fewest moves challenges, either a straight mean of 3 or the best of 3 is used, while 4×4×4 blindfolded, 5×5×5 blindfolded, and multiple blindfolded challenges are ranked using the best of 1, 2 or 3, depending on the competition. When a round begins, competitors turn in the puzzle they will use.

Speedcubing (or speedsolving) is the practice of trying to solve a Rubik's Cube in the shortest time possible. There are a number of speedcubing competitions that take place around the world. A speedcubing championship organised by the Guinness Book of World Records was held in Munich on 13 March 1981. [82]
The 3×2×1 block is usually placed in the lower portion of the left layer. The second step is to create another 3×2×1 on the opposite side. The remaining four corners are then solved using a set of algorithms known as CMLL (Corners of the Last Layer, without regards to the M-slice), which leaves six edges and four centers that are solved in ...
Petrus grew up in Gammelstaden just outside of Luleå. [4]He took up speedcubing in the early 1980s, learning it over the course of a summer when he was unemployed. [5] In 1982, he became the national champion of Sweden, and went on to finish fourth overall at the first official Rubik's Cube World Championships held in Budapest, Hungary.

[1] Contestants selected from 19 countries took part. [1] Minh Thai from the United States of America was the winner with a best time of 22.95 after three attempts for each contestant.
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 limit what arrangements are possible and mean that, of the possible unrestricted cubie arrangements, the number that are unreachable far outnumber those that are reachable.
