Information about the method
Proposer(s): Crafto22, Joseph Briggs(Shadowslice e)
Proposed: 2015
Alt Names: SSC (Shadowslice Snow Columns)
Variants: Original variant, L6e variant, Broken variant,permute-last variant, EZD variant, NoEO variant
No. Steps: 5 major though lots of flexibility. Depends on variant
No. Algs: around 50 max, 10 min.
Avg Moves: ~45 STM
Purpose(s):


Method Overview

Variations of this method has been independently invented by at least 3 people, but the person that has developed it the most, Crafto22, Is the official inventor of this method. The method is one of the most move-efficient method to ever have a sub-10 second solve(~45 STM, depending on the variant) This method is more move-efficient than roux, has less algorithms to learn than CFOP (full ECE has ~50 algorithms, full CFOP at least 78), and takes less time to learn.

The Steps

  • Solve 3 E-slice edges while orienting 3 corners on the D-layer(It doesn't matter if U and D corners are mixed; just that they are oriented).
  • Insert the final E-slice edge while orienting the U-layer corners.

there are a few ways to do this:

    • create a psuedo-F2L pair with the final e-slice edge and any corner and then either A) Insert it and then use OCLL algorithms to orient the U-layer corners, or B) Insert the pair using a F2LL-type algorithm set Winter Variation, or SLS (Shadowslice Last Slot)
    • Solve the final E-slice Edge without caring about orientation or the corner and then CLS algorithms(You only need to learn the I-category algorithms, totaling 14 algorithms(7 mirrors))
  • Use modified Square-1 algorithms to solve all the corners
    • Separate the corners into their respective layers
    • permute all the corners
  • Insert D-layer Edges while orienting the remaining edges
  • EPLL

Pros

  • Extremely low movecount(similar to Hawaiian Kociemba) but can still be fast
  • Low algorithm count compared to more popular speedsolving methods
