Purpose(s):

Last Six Edges (abbreviated LSE or L6E) is a possible last step in 3x3 speedsolving that solves the M-slice centers and edges (UF, UB, DF, DB) together with UL and UR edges. It is the last step of the Roux Method and the Ortega Method.

Possible Approaches

LSE can be solved in various ways. It should be noted, however, that Gilles Roux himself, the inventer of the Roux Method, advocates a flexible/semi-intuitive approach to LSE without a division into substeps. The optimal approach is likely a combination of the approaches below.

Layers-Based Approach

  • 1. centers, BD, and FD
  • 2. ELL

This layer-based approach seems out of place in any method ending with LSE.

Original Roux

  • 1. Orient centers and edges
  • 2. Permute UR and UL edges
  • 3. Permute the M slice

The following two approaches are commonly used in Corners first methods. Corners First Approach 1

  • 1. Solve UL or UR
  • 2. Insert UL/UR while orienting the M slice
  • 3. Permute the M slice

Corners First Approach 2

  • 1. Solve both UL and UR
  • 2. Orient and permute the M slice

L5E 1. Centers and BD 2. L5E
