1/162

|
1/162 or CMLL-Skip Method is an experimental Rubik's cube solving method invented by Emil Zedelius in 2024, trying to find an intuitive way to force a CMLL Skip in Roux-style solving. It's named "1/162", because in out of 162 solves you could have just done Roux getting the same result in a less complicated way.
Steps
1. CPFB: solving corner permuted FB with any method. Here are two possibilities a and b:
- a. CPLine + FBExtension (10 – 13 moves)
- i. CPLine: create a 1x1x3 block in the bottom left, while permuting the corners (4 – 5 moves)
- ii. FBExtension: extend the CPLine to a 1x2x3 block, like in Roux, using <r,u,R,U> (6 – 8 moves)
- b. FB + CP (11 moves on avg)
- i. FB: creating a 1x2x3 Roux-style block in the bottom left (on avg 6 moves, if you’re x2y neutral)
- ii. CP: permute the corners, using triggers like F R F’ or F’ U’ F (mirrored on the B-face) (max. 5 moves (0 – 2 commutator moves plus one trigger))
2. 6COR: orient the last 6 corners 2-gen (8 moves on avg)
- a. Intuitive approach: Try to memorize a few cases, where you can orient all corners in 3 or less moves, so you can try to go to these cases from every other case.
- b. Algorithmic approach: Algorithms for the 71 6CO cases of the Mehta method can be used, but they are shorter because there is no bar on the R face that could be destroyed.
- c. Compromise: The cases ca be reduced to 7 by orienting two arbitrary corners in RDF and RDB. (see the „6COR” section of this article)
3. SB: Solve the 1x2x3 block in the bottom right intuitively without breaking the FB (CP) or misorienting the corners. Use commutators like in the Corners First method to insert the SB edges. (approx. 13 – 18 moves)
- a. Pair up the DR corners and insert all the three remaining edges using commutators.
- b. Often, the FR edge and the BR edge can be inserted before performing the last R/R' move of 6COR.
4. CMLL-Skip! (Otherwise something went wrong in CP or CO.) (0 moves)
5. LSE: The solve can be finished like a Roux solve after CMLL. (13 moves on avg)
Pros
- Like the Roux method the 1/162 method uses fewer moves than the popular Fridrich method.
- Since in 6COR R and r moves are totally equal, the SB building can already be influenced.
- The method provides a really deep understanding of the cube; all steps are intuitively understandable.
Cons
- CP might be really difficult to get used to.
- Poor Lookahead possibilities, especially in step 3.
