ZZ-Slice is a ZZ variant invented by Matilda Teixeira aka Matilda-Cruzzader. It is inspired by a method made in the January 2021 Method Development Competition.

Steps

  1. EOSlice: Edges are oriented, while a line consisting of the DL and DR edges is formed.
  2. Pseudo F2B: The first two blocks (F2L, but missing the DF and DB edge) are built without regard to Corner Permutation.
  3. OCLL: The corners on the last layer are oriented.
  4. L6EP: The last six edges are permuted.
  5. CPBL: The corners on U and D are permuted using one algorithm.

Variants

Beginners

The pseudo F2B is built using Keyhole, while CPBL is replaced with CPLL, a parity alg (if parity comes up), x2 (or z2) and CPLL again.

Roux variant

  1. Pseudo F2B: The first two blocks (F2L, but missing the DF and DB edge) are solved like in Roux, but without regard to Corner Permutation.
  2. OCLL: The corners on the last layer are oriented.
  3. CPBL: The corners on U and D are permuted using one algorithm, Edge Permutation can be ignored.
  4. LSE: The last six edges are solved like in Roux.

Pros

  • Because CP is ignored, F2L can be solved in fewer moves.

Cons

  • Relatively high movecount (65-75 moves).
  • The Edge Orientation step may be hard to get used to for beginners.
