would use the 3OP (3-Cycle Orientation Permutation) Method, which orients and then permutes pieces using 3 cycles. As of today, methods such as 3-Style and M2 are among the fastest and most popular blind solving methods. The Old Pochmann Method, which is a method that solves one piece at a time, is a method typically used by beginner blindsolvers. Blindfolded solvers use letter patterns to help memorize sequences of moves in order to solve the cube. The lettering scheme that blindfolded solvers use is called the Speffz lettering scheme, and each sticker or individual color is given a letter. The way letters are assigned is starting on the top edge of the top face, go clockwise starting with A. The top edge of the top face is A, the right edge is B, the bottom edge is C, and the left edge is D. The same process is done on the other sides in the order top, left, front, right, back, bottom to get every edge lettered from A to X. The same process is applied to all of the corners, starting with the top left corner and going clockwise in the same face order. A cycle of piece swaps is then used with the letter E being used as a buffer location for corners and D commonly being used for edges in the Old Pochmann method. Competitions World Cube Association (WCA) Speedcubing competitions have been held every year since 2003. The World Cube Association (WCA) was formed in 2004 to govern all official competitions. For a competition to be official, it must be approved by the WCA and follow the WCA regulations. Included in the regulations is the necessity of having one or more WCA delegate in attendance. A delegate's main role is to ensure all regulations are followed during the competition. Once the competition is finished, results are uploaded to the WCA website. Judges oversee the round. Delegates help the judge. Runners give the scrambled or solved cube to the competitor. A scrambler scrambles the cube. Format The majority of puzzle competitions are held using a trimmed mean of five format. This involves the competitor executing five solves in the round in question, after which the fastest and slowest solve are disregarded and the mean of the remaining three is used. The 6×6×6 and 7×7×7 events are ranked by straight mean of three — only three solves, none
