Petrus-W

Petrus-W method Information about the method Proposer(s): WarriorCatCuber Proposed: 2020 Alt Names: none Variants: Petrus No. Steps: 6 No. Algs: 1-58 (for the last layer corners and last 5 edges) Avg Moves: 47 Purpose(s): Speedsolving Fewest Moves

The Petrus-W Method is a method for solving the 3x3x3 cube which was invented by WarriorCatCuber in 2020. The method is a variant on the Petrus method and is efficient enough to be used for advanced speedsolving.

Steps

The steps are as follows:

1. Solve a 2x2x2 block in the back of the cube
2. Expand the 2x2x2 block into a 2x2x3 block, also on the back of the cube
3. Fix the misoriented edges ZZ Method style on the cube (Edges oriented relative to where it belongs on the R,U and L layers)
4. Solve the final two corner-edge pairs while only using R, U and L moves to preserve EO. This leaves the last layer and the Down-Front edge piece to be solved
5. Solve the remaining 4 corners using COLL
6. Permute the final five edges with L5EP as in Portico

Pros

1. If you can look into the 2x2x3 block in inspection, no cube rotations are required
2. You can orient 4 edges at a time, instead of being restricted to the 2 allowed in Petrus
3. You can use M' U' M to orient edges unlike in Petrus or ZZ
4. F2L has less regrips than in Petrus F2L

Cons

1. Unlike in the ZZ method, you cannot look into EO during inspection time
2. L5EP has 7 more algorithms than EPLL
3. Unlike in Petrus or ZZ, you cannot use ZZLL or ZBLL to complete the Last Layer in one look

History

This method was proposed by Speedsolving.com member WarriorCatCuber in the ‘New Method/Substep/Concept Idea Thread.
