'''SSC''' or '''Shadowslice Snow Columns''' is a method that has variously been described as a variation on [[Orient First]], an improved version of the [[Human Thistlethwaite Algorithm]], an advanced [[Belt Method]] and a [[Columns first]] method. It is a method that requires few (28) algorithms but requires proficiency in various relatively advanced techniques such as the [[EOLine]] (which is rotated 90 degrees to create an EOEdge) as well as being able to efficiently orient corners while placing an edge. It is an efficient method which averages below 50 [[STM]] in the hands of an expert.

'''SSC''', short for '''Shadowslice Snow Columns''',(a variant with misoriented edges is called '''ECE'''), is a method that has variously been described as a variation on [[Orient First]], an improved version of the [[Human Thistlethwaite Algorithm]], an advanced [[Belt Method]] and a [[Columns first]] method. It is a method that requires few (28) algorithms but requires proficiency in various relatively advanced techniques such as the [[EOLine]] (which is rotated 90 degrees to create an EOEdge) as well as being able to efficiently orient corners while placing an edge. It is an efficient method which averages below 50 [[STM]] in the hands of an expert.
  
Intially, it was proposed simply with the '''SSC-WV''' variant though this quickly became the set of methods which is known today. After the '''SSC-M''' variant was introduced, the idea was quickly expanded on by crafto22 who created what is collectively known as the '''ECE''' variants which, while following the same basic steps as vanilla SSC-M have various advantages depending on the method. Notable variants include '''SSC-O''' and '''EZD''' for [[speedsolving]] and '''SSC-Domino''' as an [[FMC]] alternative.

==Basic Overview==

# Orient edges and place the LF and LB edges (like an EOLine rotated 90 degrees)
+
 
# Orient 3 corners on the D-layer while placing the RB edge (can be RF but [[SLS (Shadowslice Last Slot)]] and [[WV]] are for the RF slot- do not place both though).

==Method Overview==
# Place the last E-slice piece in the dictated place in the U-layer (initially creating a pseudopair for [[Winter Variation]] but later a specific place for [[SLS (Shadowslice Last Slot)]])

This method has been independently proposed by at least 3 people though it was perhaps developed most by [[Joseph Briggs]] and [[Julien Adam]]. It is one of the most move efficient methods that has been developed; potentially on par with [[Heise]], [[Human Thistlethwaite Algorithm]] and [[ZB]] depending on the variant. Also similar to Heise, it is quite intuitive and has a low algorithm count though in terms of procedure it is more similar to HTA or [[PCMS]].

* EZD
* '''SSC-WV''' or '''SSC-Winter Variation'''

** For LEE, the edges are separated before being permuted with a set of algorithms.

* Broken
**Do not do EO until the last step with LEE- higher movecount though easier lookahead.

** Similar to the Belt method, the F2L is solved after step 2 using {R2,L2,M2,U,D}

**The two layers are solved separately rather than doing both together as with other methods
+
* Permute last

** This is even more similar to the Belt method where edges are separated then PLL is applied to both sides.
**the edges are separated in the last step and solve using an algorithm rather than intuitively.
+
* FR
* '''ECE-A'''
+
** The FR(or BR) is left out of the E-slice(only making a pseudotriplet abd positioning one corner in LUF) and solve it later.
**The last eight edges are solved by orienting the U layer edges while placing the D layer edges followed by [[EPLL]]
 
  
Note: in his variants (ie the ECE styles), crafto22 uses WV as opposes to SLS in a manner consistent with SSC-WV
+
** This helps with lookahead in the first few steps and you can influence the UL and Ur edges while solving the FR edge

(SSC-FR : orientated edges)
  
==Experimental Corner Orientation==
+
(ECE-FR : misoriented edges)
A newer recent development created by SqAree in collaboration with Shadowslice e. It is an alternative way of orienting the corners after the EoEdge, is much more efficient than any other style and can lead to the first two steps being done in under 20 moves in almost all cases; often in much less; it averages around 15-17 moves in a speedsolve and even less in an FMC setting. The brief style is:
 
# separate FR and BR
 
# Form a 1x1x3 "triplet" with one of the edges
 
# Form a 1x1x2 "pair" with the other one
 
# OL5C
 
# Finish.
 
  
A more in depth version:(assuming green on front, white on top)
 
# Separate the front right (green/red) and back right (blue/red) edges (ie place either the front right (green/red) edge in the U layer and the back right (blue/red) in the D layer or vice versa)
 
# Create a "triplet" (a 1x1x3 or column) using the edge in the D-layer (technically a pseudo triplet) of pieces so that if the edge in in the Down Left position, there would be a white or yellow sticker in the front down left position and a yellow or white sticker in the back down left position. Place this in the down left slot.
 
# Create another similar pseudopair (not triplet: this one is a 1x1x2) using the remaining e-slice edge in the U-layer. Place this in the front up slot with the yellowor white sticker on the corner facing to the left (ie being in the left-up-front position).
 
# Look at the right side to determine the O5C (orient 5 corners) case and execute the algorithm.
 
# Bring the unsolved e-slice edges to UR and DR using only U and D moves then do an R or R' to solve them.
 
 
==Potential Improvements==
 
As a relatively new group of methods, SSC will undoubtedly continue to evolve and change. Some of the more prominent ideas for improving the method and techniques which could be used to improve the efficiency include:
 
* Adding an algorithm set for the permuting of corners which for when the FR and BR edges are swapped (this could lead to a more efficient EoEdge+1).
 
* An entirely new last phase (ie when the cube has been reduce to act likes domino) which could be more efficient and or have better lookahead. Hopefully both.
 
* Predicted separation- paricularly useful for EZD.

Purpose(s):

SSC, short for Shadowslice Snow Columns,(a variant with misoriented edges is called ECE), is a method that has variously been described as a variation on Orient First, an improved version of the Human Thistlethwaite Algorithm, an advanced Belt Method and a Columns first method. It is a method that requires few (28) algorithms but requires proficiency in various relatively advanced techniques such as the EOLine (which is rotated 90 degrees to create an EOEdge) as well as being able to efficiently orient corners while placing an edge. It is an efficient method which averages below 50 STM in the hands of an expert.

Intially, it was proposed simply with the SSC-WV variant though this quickly became the set of methods which is known today. After the SSC-M variant was introduced, the idea was quickly expanded on by Julien Adam who created what is collectively known as the ECE variants which, while following the same basic steps as vanilla SSC-M have various advantages depending on the method. Notable variants include SSC-O and EZD for speedsolving and SSC-Domino as an FMC alternative.


Method Overview

This method has been independently proposed by at least 3 people though it was perhaps developed most by Joseph Briggs and Julien Adam. It is one of the most move efficient methods that has been developed; potentially on par with Heise, Human Thistlethwaite Algorithm and ZB depending on the variant. Also similar to Heise, it is quite intuitive and has a low algorithm count though in terms of procedure it is more similar to HTA or PCMS.


General Structure

  1. Solve EoEdge (EOLine but placing FL and BL rather than DF and DB).
  2. Orient corners and edges and place FR and BR edges.
  3. Solve the rest of the cube using one of many variants.

Pros

  • Low movecount
  • Ergonomic- mostly {R,U,D,M}
  • Low algorithm count compared to more popular speedsolving methods

Cons

  • Can be difficult to transition from other popular methods as it does not directly solve many pieces until the final few steps.
  • Pseudopairs can be difficult to get used to.
  • Lookahead can be made difficult due to the lack of direct solving
  • It is generally acknowledged that the current last step variants are not the best and so it is an area of constant development so any variant learned may be out of date or superseded by better variants relatively quickly.

Beginner's SSC

  1. Solve EoEdge and place one additional E-slice edge
  2. Orient 3 D-layer corners and create a pseudopair to insert the final E-slice edge
  3. OCLL
  4. Separate corners
  5. Solve corners
  6. LEE (last eight edges)

Intermediate SSC

  1. Solve Eoedge and place one additional E-slice edges
  2. Orient 3 D-layer corners and create a pseudopair
  3. WV (winter variation) using the pseudopair
  4. Separate corners
  5. Solve corners
  6. LEE (last eight edges)

There are actually quite a few ways to go about intermediate SSC however the above is the one most frequently recommended by those most familiar with the method.

Advanced SSC

  1. EoEdge
  2. Orient corners
    1. Create a pseudopair and pseudotriplet using the remaining E-slice edges
    2. OL5C
  3. Solve corners
  4. LEE

In fact there are many different last two steps for Advanced SSC similar to Intermediate and by the time one attains this level they should evaluate all the options in order to find the variant most suited to them.

Variants

There are quite a few variants to SSC, mostly to do with differences in the solving of the final step(s)

  • EZD
    • For LEE, the edges are separated before being permuted with a set of algorithms.
    • This is the variant used by Julien Adam to obtain his sub-13 averages.
  • Broken
    • Similar to the Belt method, the F2L is solved after step 2 using {R2,L2,M2,U,D}
    • PLL
  • Permute last
    • This is even more similar to the Belt method where edges are separated then PLL is applied to both sides.
  • FR
    • The FR(or BR) is left out of the E-slice(only making a pseudotriplet abd positioning one corner in LUF) and solve it later.
    • This helps with lookahead in the first few steps and you can influence the UL and Ur edges while solving the FR edge
