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.
Contents
Steps
The steps are as follows:
- Solve a 2x2x2 block in the back of the cube
- Expand the 2x2x2 block into a 2x2x3 block, also on the back of the cube
- Fix the misoriented edges ZZ Method style on the cube (Edges oriented relative to where it belongs on the R,U and L layers
- 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
- Solve the remaining 4 corners using COLL
- Permute the final five edges with L5EP as in Portico
Pros
- If you can look into the 2x2x3 block in inspection, no cube rotations are requires
- You can orient 4 edges at a time, when you have to fix them 2 at a time in Petrus
- You can use M' U' M to orient edges unlike is Petrus or ZZ
- F2L has less regrips than in Petrus F2L
Cons
- Unlike in the ZZ method, you cannot look into EO during inspection time
- L5EP has 7 more algorithms than EPLL
- Unlike in Petrus or ZZ, you cannot use ZZLL or ZBLL to complete the Last Layer in one look.
