Roux

Block building, CMLL, and the last six edges for a low move count.

1. 1. Introduction

   An overview of the Roux method, which builds two 1x2x3 blocks, solves the top corners, and finishes with the last six edges.

2. 2. First Block

   How to build the first 1x2x3 block in Roux by example, aiming for 8-10 moves.

3. 3. Second Block

   How to build the second 1x2x3 block opposite the first without disturbing it, with six example ideas.

4. 4. CMLL (Top Corners)

   Solve the top corners after both blocks are built, using 2-look CMLL or the full 42-algorithm CMLL set.

5. 5. LSE: Edge Orientation

   Orient the last six edges using only M and U turns, starting with the Arrow case and cycling the other ten cases into it.

6. 6. LSE: Permute UL/UR

   Place the UL and UR edges by moving them to the bottom layer without changing edge orientation, then bringing them back up with M2.

7. 7. LSE: Permute M Slice

   Finish the solve by permuting the last four edges in the M slice, covering 2 dots, 4 dots, and 3-edge cycles.

8. 8. Example Solves

   Three complete Roux solves with scrambles, move-by-move explanations, and a stepping cube to follow each solution.

9. 9. Advanced Roux

   Techniques that take a Roux solve further, including EOLR, non-matching blocks, second-block efficiency, and CMLL recognition, with links to experienced Roux solvers.
