Seven Simul Tutorial for Rubik's Clock

Introduction

• Seven Simul is an advanced, efficient method for solving Rubik's Clock.
• Recommended to learn Shirin method first for transition.
• "Seven Simul" refers to solving in seven or fewer simultaneous moves.
• Developed by Lianci Zhang (2021) and independently by Benjamin Paul (2022).

Benefits of Seven Simul

• More efficient than other methods.
• No need to flip the clock during the solve.
• Achieved a 2.97-second North American record using this method.

Basic Concepts

• Simultaneous Move: Turning dials for both pins at the same time, with at least one pin up.
• Notation:
  • C = Center
  • U, R, D, L = Edges (Up, Right, Down, Left)
  • Corners denoted by two letters (UR, UL, DL, DR)
  • Lowercase letters for starting side, uppercase for opposite.

Memorization Process

1. Initial Setup:
   • Memorize 5-6 letters, broken into pairs.
   • Use words/sounds for pairs (similar to blind solving).
2. Step-by-Step Memorization Example:
   • Calculate difference (e.g., C - D) and convert to a letter.
   • Add/subtract clock positions and convert to letters.
   • Create letter pairs for easier memorization.
3. Execution:
   • Start from uppercase side after memorization.
   • Follow pin positions and execute moves based on memorized letters.

Solving the Clock

• Pin Positions:
  • Lowercase DL, UR, Backslash, UL, and L pin positions.
• Intuitive Block Building:
  • Create 2x2 and 3x2 blocks using intuitive moves.
• Execution of Moves:
  • Convert memorized letters into moves for each corresponding pin position.

Advanced Tips

• Practice:
  • Frequent practice to improve speed and understanding.
  • Use Joshua Marriott’s training tool for memorization speed.
• Memorization Technique:
  • Run through combinations mentally and practice the order of execution.

Conclusion

• Acknowledge the steep learning curve.
• Encouragement to practice and use available resources.
• Invitation to comment with questions or further learning interests.
