For beginner cubers tackling the last layer of the 4×4 Rubik’s Cube (also known as the PLL – Permutation of the Last Layer), here’s a simplified tutorial using only four basic algorithms. These algorithms are easy to learn and will help you complete the final layer without needing advanced techniques. Let’s get started:

Step 1: Solve the Last Layer Centers

Before applying the algorithms, ensure that all the center pieces on the last layer match their corresponding center colors. This step is similar to aligning centers on a 3×3 cube.

Step 2: Position Last Layer Edges (OLL Parity Fix)

If you encounter a parity issue with the last layer edges (OLL parity), follow these steps to position them correctly:

1. OLL Parity Fix Algorithm:

• Hold the cube with the parity issue facing you.
• Perform the following algorithm:
  Rw U2 x' Rw U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw U2 Rw'
• Explanation:
  • Rw: Turn the right inner layer clockwise.
  • U2: Rotate the top layer 180 degrees (half turn).
  • x': Rotate the cube on the x-axis counterclockwise.
  • Repeat the sequence until the edges are correctly positioned.

Step 3: Permute Last Layer Edges (PLL)

Once the edges are correctly positioned, use the following four basic PLL algorithms to permute the last layer edges. Each algorithm corresponds to a specific case where two adjacent edges need to be swapped. Execute the algorithm that matches your cube’s configuration.

2. PLL Algorithm 1 (Adjacent Edge Swap):

   Rw U2 Rw U2' Rw' U2 Lw U2' Rw' U2 Rw U2' Rw'

3. PLL Algorithm 2 (Adjacent Edge Swap):

   Rw' U2 Lw' U2 Rw U2 Rw' U2 Rw U2 Rw' U2' Rw

4. PLL Algorithm 3 (Adjacent Edge Swap):

   Uw2 Rw U2 Rw' U2 Rw U2 Rw' U2 Rw U2 Rw' U2 Rw' Uw2

5. PLL Algorithm 4 (Adjacent Edge Swap):

   Uw2 Rw' U2 Rw U2 Rw' U2 Rw U2 Rw' U2 Rw U2 Rw Uw2

Step 4: Final Adjustments

After applying the PLL algorithm corresponding to your cube’s configuration, check the entire cube for correct edge and corner orientations. Make any necessary adjustments to complete the solve.

Tips:

• Practice Regularly: Master these algorithms through consistent practice to improve your solving speed and accuracy.
• Algorithm Memorization: Focus on memorizing and understanding each algorithm to apply them effectively during solves.

Solving the 4×4 Rubik’s Cube, also known as the Rubik’s Revenge, is similar to solving the classic 3×3 cube but requires a few additional steps due to the increased complexity. Here’s a step-by-step guide to solving the 4×4 Rubik’s Cube:

Step 1: Solving the Centers

1. Build the Center Pieces:

• Unlike the 3×3 cube, the 4×4 cube has center pieces that do not move relative to each other. Start by solving the center pieces of each face based on color.
• Treat the cube like a 3×3 at this stage. Align the center pieces correctly, matching the adjacent edge colors.

Step 2: Pairing the Edge Pieces

1. Pair Similar Edges:

• Solve the edges by pairing similar pieces together based on color.
• Find two edge pieces with matching colors and align them next to each other.
• Use the following algorithm to pair and place the edges:
  • [Rw, U, Rw’] (or its inverse [Lw’, U’, Lw]): This algorithm helps pair the edges without disturbing the solved centers.

Step 3: Creating the 3×3 Stage

1. Reduce to a 3×3 Cube:

• Treat the cube as a 3×3 cube by reducing it to that size. This involves solving the remaining pieces as you would on a standard 3×3 cube.
• Start by solving the cross on one face and then the corners.
• Use familiar 3×3 algorithms and techniques to solve the cube up to the last layer.

Step 4: Solving the Parity Errors

1. Identify Parity Errors:

• On the 4×4 cube, you might encounter parity errors where the cube appears to be unsolvable using standard 3×3 methods.
• Common parity errors include OLL parity and PLL parity, which affect the orientation and permutation of certain pieces.

1. Fix Parity Errors:

• To fix parity errors, use specific algorithms designed to address these issues. For example:
  • OLL Parity Algorithm: [r U2]2 (or its inverse [l’ U2]2) to fix orientation parity.
  • PLL Parity Algorithm: [2U (2L 2R)2]*2 (or its inverse) to fix permutation parity.

Step 5: Final Adjustments

1. Fine-Tune the Cube:

• After solving the cube using the above steps, perform any necessary final adjustments to ensure all pieces are correctly aligned and oriented.
• Practice finger tricks and cube rotations to improve speed and efficiency.

Tips:

2. Inefficient Look-Ahead

• Mistake: Focusing only on the current step without anticipating the next moves can slow down solve times.
• Solution: Practice look-ahead by tracking pieces as you solve. Train yourself to anticipate the next steps while executing the current ones, which improves overall efficiency.

3. Ignoring Finger Tricks

• Mistake: Using inefficient turning techniques or neglecting advanced finger tricks can limit speed improvement.
• Solution: Invest time in learning and mastering efficient finger tricks for each move. Practice regularly to build muscle memory and improve speed.

4. Lack of Algorithm Knowledge

• Mistake: Relying solely on intuitive solving methods without learning algorithms for advanced techniques (e.g., OLL, PLL) can slow down progress.
• Solution: Dedicate time to learn and memorize algorithms for key stages of the solve. Use resources like algorithms sheets, online tutorials, and practice apps.

5. Skipping Practice on Weak Areas

• Mistake: Focusing only on favorite algorithms or stages of the solve while neglecting weak areas can create imbalances in skill development.
• Solution: Identify and target weaknesses in your solving technique. Allocate practice time specifically to improve these areas, whether it’s lookahead, finger tricks, or algorithm memorization.

Additional Tips:

• Consistent Practice: Regularly practice solving the cube, focusing on different aspects of your technique each session.
• Record and Analyze: Use video recordings of your solves to identify mistakes and areas for improvement.

2. Wide Moves (r, l, f, b)

• Learn to execute wide moves (r, l, f, b) efficiently.
• Use your ring finger or pinky to flick the inner layers, minimizing hand movement.
• Example: For r (Right Wide Turn), use your ring finger to flick the inner right layer downward.

3. M-slice Moves (M, E, S)

• Master M-slice (middle layer) moves (M, E, S) for more fluid cube rotations.
• Use your ring and middle fingers for M (Middle) moves, and your index finger for E (Equatorial) and S (Standing) moves.
• Example: For M (Middle Turn), use your ring finger to push the middle layer across.

4. Flicking Techniques

• Practice using quick, controlled flicks for optimal turning speed.
• Utilize a combination of finger movements (thumb, index, middle) for different face rotations.
• Example: Use your thumb for U (Up) turns, index finger for R (Right) turns, and middle finger for F (Front) turns.

5. Advanced Algorithms

• Implement advanced algorithms that incorporate efficient finger tricks.
• Focus on fluid execution and minimal pauses between moves.
• Example: Practice algorithms like the OLL (Orientation of Last Layer) and PLL (Permutation of Last Layer) using optimized finger movements.
