RUBIX CUBE X AND O METHOD FREE

While this may seem good, many faster Rouxers are of the opinion that it is simply better to influence the EO step and not go to all the hassle of placing UL/UR on D and having to recognise an OLLCP. The user then will get a 4a skip and a very easy 4b step. Pinkie Pie: A variant proposed by Alex Lau in 2016, it involves orienting the UL/UR edges on the D layer while using an OLLCP algorithm to orient the remaining edges and solving the remaining corners. There is a complete guide to using non-matching blocks at this link. Otherwise, corner recognition will be difficult if the choice is made to use a different recognition method. If a new Roux solver plans to use non-matching blocks, it may be best to learn this method for recognizing corners. After building non-matching blocks, the fastest way to recognize CMLL is through the use of ACRM. This means that the D-layer colors of the two blocks don't have to match. Non-Matching Blocks: Another improvement is to expand to solving any of the four possible second blocks. Soon after, Thom Barlow suggested changing the name to CLLEO. CMLL + EO was an idea originally being developed by Thom Barlow under the name KCLL. This allows for manipulation of edge orientation, leading to an easier LSE. The centers can be corrected directly before CMLL with either u M' u' or u' M' u.ĬMLLEO: Some Roux users have learned multiple algorithms for each CMLL case, each affecting edges in a different way. This allows for more efficiency and allows Roux users to take advantage of pre-built blocks. Non-Matching Centers: The first two blocks can be built around incorrect centers. This is very useful when there are a lot of free, pre-built blocks and pairs. You can build part of one and finish the other later. However, if one practices doing one-handed M-slices, it can be done very well but only with a table (which shouldn't be a concern in competitions).įree/Non-Linear Blocks: The first block and second block do not need to be built in that order. The M-slice is very difficult with OH, and OH Roux solvers almost always need to utilize table abuse and therefore can pretty much never solve one-handed away from a table or other surface.

With 7x7x7 and 6圆圆, many argue that Roux is essentially unusable however, with practice, one may be able to do well with it on big cubes.

The M-slice becomes increasingly difficult with higher order puzzles.

It is a DNF because M uses both the R and L face in one.

Since the M-slice is used often, especially in the final stages, there is a larger chance of a DNF rather than a +2 if the solver misses the second flick in an M2, or if the solver misses the last M move.

The reliance on r and M moves may also be difficult for some people, so much so that cubers who have trouble with M turns should probably not use this as their main method (or better, practice the M moves).

Block building can be difficult for a beginner to get used to.

The LSE step of Roux is very easy to master, as it has easy lookahead and allows for fast, 2-gen MU TPS.

The blockbuilding and intuitive nature of the method allows for rapid improvements in lookahead and inspection.

CMLL is one of the best algorithm sets as there are only 42 cases and most algorithms are fast OLLCPs from CFOP.

After the first block is built the rest of the cube can be solved mostly with R, r, M and U moves thus eliminating rotations.

It is also more intuitive and requires fewer algorithms.

Like the Petrus method, the Roux method uses fewer moves than the popular Fridrich method.

Steps 3 and 4 are referred to as the Last 10 Pieces Pros This step is sometimes also called L4E or L4EP. Solve the centers and edges in the M slice. After this step, both the left and right side layers should be complete.Ĥc. Solve the UL and UR edges, preserving edge orientation. Orient the 6 remaining edges using only M and U moves (UF, UB, UL, UR, DF, DB need to be oriented correctly).Ĥb. The remaining four corners can also be solved in two steps, which requires fewer algorithms.Ĥa. However, these sets aren't as efficient as CMLL because they preserve pieces which CMLL does not. It is also possible to use COLL and some other CLL algorithm sets.

This set of algorithms is commonly referred to as CMLL. If performed in one step, there are 42 algorithms. Simultaneously orient and permute the remaining four corners on the top layer (U-slice). Steps 1 and 2 are referred to as the First Two Blocksģ.

After this step, there should be two 1x2x3 blocks: one on the lower left side, and one lower right side, leaving the U slice and M slice free to move. Build a second 1x2x3 block opposite of the first 1x2x3 block, without disrupting the first 1x2x3 block. Build a 1x2x3 Block anywhere on the cube.Ģ.
