Hall-4 method Information about the method Proposer(s): Daylen Hall Proposed: February 2024 Alt Names: D-4 Variants: No. Steps: 6 No. Algs: 42 CLL ,6 L4W, rest is commutators. Avg Moves: 120-150 Purpose(s): Speedsolving

Hall-4 is a 4x4 speedsolving method invented by Daylen Hall in February of 2024. It utilizes Yau and Direct Solving techniques. It has good look ahead for most of the solve. It’s like a 4x4 version of Cross-1.

The Steps

• 1. Build two opposite centers( your top and bottom colors)

• 2. Build 3 of your cross edges like in Yau.

• 3. Finish off the 4 remaining centers and line them up with the cross. Then rotate the cube so the cross pieces are in the back leaving the F and U face free to move.

• 4. Solve the F3L pairs. This step has good look ahead and uses lots of tricks. The solve from here is also rotationless.

• 5. CLL/CDFLL-Solve the corners.

• 6. 4-Look L10W(Last 10 Wings)

Pros

• Solves pieces directly.
• Good look ahead and ergonomics throughout the solve.
• Uses techniques from well know methods like Yau and CFOP.
• Few rotations.
• Fewer moves than most methods.

Cons

• Needs a good understanding of commutators.
• F3L step can be hard for beginners.
• L10W needs lots of practice to get good at.
