Petrus-W method
Information about the method
Proposer(s): WarriorCatCuber

No. Algs: 1-58 (for the last layer corners and last 5 edges)
Avg Moves: 47

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.


The steps are as follows:

  1. 2x2: Solve a 2x2x2 block in the back of the cube
  2. 2x2x3: Expand the 2x2x2 block into a 2x2x3 block, also on the back of the cube
  3. 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)
  4. 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
  5. COLL: Solve the remaining 4 corners using COLL
  6. L5EP: Permute the final five edges with L5EP as in Portico


  • Very few cube rotations are required; if you are able to plan your 2x2x3 in inspection, the number drops to zero
  • EO is more free than in Petrus
  • L2P has less regrips than in Petrus F2L


  • 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


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.
