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.

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 ...
