Introduction to the Roux Method

The Roux method is a sophisticated yet intuitive approach to solving the Rubik’s Cube, favored by both beginners and advanced speedcubers. Unlike traditional methods that rely heavily on layer-by-layer techniques, Roux emphasizes block-building and efficient manipulation of the cube with minimal rotations. This guide breaks down each step of the Roux method, providing clear instructions and tips to make your solving experience both comprehensive and easy to follow.

Step 1: First Block (FB)

Building a 1x2x3 Block on the Left Side

The foundation of the Roux method lies in constructing the first block. This block serves as the anchor for the entire solve.

Objective: Create a 1x2x3 block on the left side of the cube, typically on the left-down-front (LDF) section.
- Include three edges and three corners in this block.
- Use the left center piece as an anchor point.
Approach:
- Start by positioning a DL (Down-Left) edge piece correctly.
- Solve the two adjacent corner pieces intuitively, ensuring they align with the DL edge.
- Incorporate the remaining edge piece to complete the block.
Tips:
- Use R (Right), U (Up), and L (Left) moves primarily to avoid unnecessary cube rotations.
- Practice block-building techniques to enhance efficiency and reduce move counts.
- Plan your moves during the inspection time to streamline the solving process.

Common Challenges and Solutions

Misaligned Pieces: Ensure each piece is not only in the correct position but also correctly oriented to prevent disruptions in later steps.
Overcomplicating Moves: Focus on simple, intuitive moves rather than forcing complex algorithms at this stage.
Time Management: Allocate sufficient time to master this step, as it forms the core of the Roux method.

Step 2: Second Block (SB)

Constructing the Opposite 1x2x3 Block

With the first block in place, the next step is to build a mirror block on the opposite side of the cube. This establishes a robust framework for the final stages of the solve.

Objective: Build a second 1x2x3 block on the right side (RDF) of the cube without disturbing the first block.
Approach:
- Utilize R, r, M (Middle slice), and U moves to position and orient the necessary pieces.
- Ensure that the M slice remains flexible to facilitate edge reorientation later.
- Mirror the techniques used in constructing the first block to maintain consistency.
Tips:
- Maintain visualization of how each move affects both blocks simultaneously.
- Practice pairing pieces efficiently to minimize the number of moves required.
- Keep the building process intuitive, relying less on memorized algorithms.

Enhancing Block Efficiency

Edge Pairing: Focus on pairing edges with their corresponding corners to streamline block construction.
Minimize Rotations: Use fewer cube rotations by planning sequences that keep both blocks intact.
Flexibility: Maintain flexibility in the M slice to adjust edges during the final stages.

Step 3: CMLL (Corners of the Last Layer)

Solving and Orienting Remaining Corners

With both blocks established, the next phase focuses on resolving the corners of the last layer. This step ensures that all four top-layer corners are correctly oriented and positioned.

Objective: Solve all four corners of the last layer in one integrated step.
Approach:
- Identify the current orientation of each corner piece.
- Apply specific CMLL algorithms to orient and permute the corners simultaneously.
- Start with two-look CMLL, handling orientation and permutation separately before advancing to full CMLL.
Tips:
- Familiarize yourself with common corner patterns to recognize cases quickly.
- Learn a subset of algorithms initially, then gradually incorporate the full set for greater flexibility.
- Practice algorithms to enhance speed and reduce recognition time during solves.

Mastering CMLL Algorithms

Algorithm Familiarity: Begin with fundamental CMLL algorithms and expand your repertoire as you become more comfortable.
Movement Efficiency: Focus on executing algorithms smoothly to maintain solve momentum.
Case Recognition: Develop the ability to quickly identify corner orientations to apply the correct algorithm promptly.

Step 4: LSE (Last Six Edges)

Solving the Remaining Edges

The final step involves resolving the last six edges of the cube, ensuring that all edge pieces are correctly oriented and positioned.

Objective: Preserve the established blocks while solving the last six edges efficiently.
Approach:
1. Edge Orientation (EO):
  - Orient all remaining edges to align with the top and bottom layers.
  - Use M and U moves to flip "bad edges." Common cases include 0, 2, or 4 edges needing orientation.
2. UL/UR Edges:
  - Solve the two upper layer edges, ensuring they fit seamlessly with the existing blocks.
  - Utilize algorithms that target only these edges to prevent disrupting other parts of the cube.
3. M-slice Edges:
  - Finish solving the two edges in the M-slice by permuting them to their final positions.
  - Employ strategies like U-perms, H-perms, or Z-perms for efficient permutation.
Tips:
- Focus on maintaining the integrity of both the first and second blocks throughout this process.
- Practice intuitive edge positioning to reduce reliance on memorized algorithms.
- Keep track of edge positions to avoid unnecessary moves and optimize the solving sequence.

Enhancing LSE Efficiency

Recognition Patterns: Train yourself to recognize edge patterns quickly to apply the appropriate permutation algorithms.
Algorithm Execution: Execute algorithms smoothly and consistently to maintain solving speed.
Edge Tracking: Develop a systematic approach to tracking edge positions to prevent confusion during permutation.
