The M2 method is a popular technique for solving the Rubik’s Cube blindfolded. It involves memorizing and executing specific sequences of moves to solve the cube without looking at it. M2 stands for “Middle Slices” and “2-Cycles,” referring to the moves used in this method. Here’s a step-by-step tutorial on how to solve the Rubik’s Cube blindfolded using the M2 method:
Prerequisites
Before attempting the M2 method, make sure you are comfortable with the following:
- Basic understanding of Rubik’s Cube notation (F, B, U, D, L, R).
- Ability to solve the cube using beginner or intermediate methods.
- Familiarity with blindfolded solving concepts like memorization techniques and execution under blindfold.
Steps to Solve Using M2 Method
1. Memorization Phase
- Assign Letters to Cube Pieces:
- Use a consistent lettering scheme to label each sticker position on the cube (e.g., A-H for corners, I-T for edges).
- Memorize the current state of the cube by associating letters with the positions and orientations of corners and edges.
- Memorize Target Permutation:
- Determine the target positions and orientations of the cube’s pieces after solving.
- Memorize the sequence of letters representing the desired arrangement of corners and edges.
2. Execution Phase
- Scramble the Cube:
- Start with the cube in a solved state.
- Perform a specific set of moves (scramble) to create a randomized cube configuration.
- Blindfold Yourself:
- Put on your blindfold or close your eyes to begin the solving process.
- Execute M2 Algorithm:
- Use the M2 algorithm to solve the cube layer by layer without looking.
- M2 involves using specific slice moves (middle layer turns) and 2-cycle moves (swapping pairs of pieces). M2 Moves:
- Middle Slice Moves:
- M: Turn the middle slice clockwise (90 degrees).
- M’: Turn the middle slice counterclockwise (90 degrees).
- M2: Turn the middle slice twice (180 degrees).
- 2-Cycle Moves:
- Examples include swaps like (UF) (UB), (UR) (UL), (FR) (FL) for edges and similar swaps for corners.
- Repeat Until Solved:
- Execute the M2 algorithm based on the memorized sequence of letters.
- Perform the necessary moves to achieve the target permutation of corners and edges.
3. Reconstruction Phase
- Remove Blindfold:
- Once you believe the cube is solved, remove your blindfold or open your eyes.
- Check and Verify:
- Verify the cube’s state visually to ensure it matches the target permutation you memorized.
- Review and Practice:
- Reflect on your solving process and practice memorization and execution to improve your blindfolded solving skills using the M2 method.
Tips for Success
- Start with Simple Cases: Begin by solving a few pieces blindfolded before attempting full cube solves.
- Use Memorization Techniques: Develop effective memorization strategies such as letter pairings or story-based mnemonics.
- Practice Regularly: Consistent practice is key to mastering blindfolded solving techniques like M2.
- Seek Feedback: Get feedback from experienced blindfolded solvers and participate in blindfolded solving communities for support and improvement.
By following this tutorial and practicing regularly, you can develop proficiency in solving the Rubik’s Cube blindfolded using the M2 method. Keep challenging yourself and enjoy the journey of mastering blindfolded cubing!
