Introduction to Roux

Roux relies less on algorithms and more on freedom of movement. It uses the M slice (middle layer) heavily.

The 4 Steps

1. First Block (FB)

Build a 1x2x3 block on the Left side.

  • Totally intuitive.
  • You can use the M-slice and U-layer freely.

2. Second Block (SB)

Build a 1x2x3 block on the Right side.

  • Now the Left and Right sides are solved.
  • The M slice and U layer are still free to move.

3. CMLL (Corners of Last Layer)

Solve the 4 corners of the top layer in one step (Orientation + Permutation).

  • There are 42 algorithms (similar to OLL/PLL but focused on corners).
  • Beginners can use 2-Look CMLL (Orient then Permute).

4. LSE (Last Six Edges)

Solve the remaining 6 edges (4 on top, 2 on bottom) using only M and U moves.

  1. Orientation: Flip bad edges so they can be solved.
  2. UL/UR: Place the left and right edges.
  3. Last 4: Solve the remaining centers and edges.

Why Roux?

  • Efficiency: Average move count is ~48 moves (vs ~60 for CFOP).
  • Lookahead: Since you track fewer pieces (blocks instead of cross+pairs), it can be easier to plan ahead.
  • Table Abuse: Not great for one-handed, but amazing for two-handed solving.
