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:
- 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.
- PLL Algorithm 1 (Adjacent Edge Swap):
Rw U2 Rw U2' Rw' U2 Lw U2' Rw' U2 Rw U2' Rw'
- PLL Algorithm 2 (Adjacent Edge Swap):
Rw' U2 Lw' U2 Rw U2 Rw' U2 Rw U2 Rw' U2' Rw
- PLL Algorithm 3 (Adjacent Edge Swap):
Uw2 Rw U2 Rw' U2 Rw U2 Rw' U2 Rw U2 Rw' U2 Rw' Uw2
- 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.
- Stay Patient: Solving the 4×4 Rubik’s Cube can be challenging at first, but with perseverance and practice, you’ll achieve success.
By following this tutorial and practicing with these four basic PLL algorithms, you’ll be able to solve the last layer of the 4×4 Rubik’s Cube efficiently as a beginner. Happy cubing!
