The Petrus-W Method is a method for solving the 3x3x3 cube 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:
- 2x2: Solve a 2x2x2 block in the back of the cube
- 2x2x3: Expand the 2x2x2 block into a 2x2x3 block, also on the back of the cube
- EO: Fix the misoriented edges on the cube with ZZ-style EO (Edges oriented relative to where it belongs on the U, F, and D layers)
- L2P: Solve the final two corner-edge pairs while only using R, U and L moves to preserve EO. This leaves only the last layer and the Down-Front edge piece to be solved
- COLL: Solve the remaining 4 corners using COLL
- L5EP: Permute the final five edges with L5EP as in Portico
Pros
- Very few cube rotations are required; if you are able to plan your 2x2x3 in inspection, the number drops to zero
- You can orient 4 edges at a time, instead of being restricted to 2 at a time as in Petrus
- EO is more free than in Petrus or ZZ
- L2P has less regrips than in Petrus F2L
Cons
- Just like Petrus, you cannot look into EO during inspection time
- L5EP has slightly more algorithms than EPLL
- Unlike in Petrus or ZZ, you cannot easily solve the last layer in one look
History
Petrus-W was originally proposed on the SpeedSolving Forums by user WarriorCatCuber on February 6, 2020. According to the creator, the idea came from a misinterpretation of another user's critique of a solve with the Petrus Method. After some thought and improvement, WarriorCatCuber decided to show the other forum users his new idea.
