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 SSCWV variant though this quickly became the set of methods which is known today. After the SSCM 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 SSCM have various advantages depending on the method. Notable variants include SSCO and EZD for speedsolving and SSCDomino as an FMC alternative.
Contents
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
 Solve EoEdge (EOLine but placing FL and BL rather than DF and DB).
 Orient corners and edges and place FR and BR edges.
 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current last step variants are not the best and so it is an area of constant development so any variant learned may be out of date or superseded by better variants relatively quickly.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
 Solve EoEdge and place one additional Eslice edge
 Orient 3 Dlayer corners and create a pseudopair to insert the final Eslice edge
 OCLL
 Separate corners
 Solve corners
 LEE (last eight edges)
Intermediate SSC
 Solve Eoedge and place one additional Eslice edges
 Orient 3 Dlayer corners and create a pseudopair
 WV (winter variation) using the pseudopair
 Separate corners
 Solve corners
 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
 EoEdge
 Orient corners
 Create a pseudopair and pseudotriplet using the remaining Eslice edges
 OL5C
 Solve corners
 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 sub13 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 Eslice(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
