Purpose(s):


The Roux Method (French pronunciation: [ʁu]) is a 3x3 speedsolving method invented by Gilles Roux. Unlike the Fridrich and Petrus methods, the inventor of this method has used it to achieve an official sub-15 average. Similarities can be drawn to the Petrus method's block building and the Waterman method's layer-on-the-left and edges-last aspects.

The Steps

1. Build a 1x2x3 block anywhere on the cube.

2. Build a second 1x2x3 block opposite of the first 1x2x3 block, without disrupting the first 1x2x3 block. 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.

3. Simultaneously orient and permute the remaining 4 corners on the top layer (U-slice). You can use CMLL,COLL, or Corner OLL's (along with T and Y permutation) to do this.

4. Orient the 6 remaining edges (UF, UB, UL, UR, DF, DB need to be oriented correctly).

5. Solve the left and right layer edges. After this step, both the left and right side layers should be complete.

6. Solve the centers and edges in the M slice, see Last Six Edges.

Pros

Like the Petrus method, the Roux method uses fewer moves than the popular Fridrich method. It is also more intuitive and requires fewer algorithms. 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.

Cons

Block building can be difficult for a beginner to get used to. 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 practice practice the M moves). Slice turns can also be slower than using a quarter-turn metric.
