LSFB, or Light Slice Fire Blocks (a parody name of SSC) is a method that was originally planned to be submitted for the January-February 2021 Method Development Competition by Team Kübirz (with a majority of the work done by [Ryan Kennelly]), but was later scrapped in favour of ECP Method. It has an extremely low number of algorithms, making it beginner friendly, while also introducing the solver to advanced concepts like EO.

## Steps

1. Build a 2x2x1 block on the left side of the cube, like in the Roux method, just without the front pair.

2. Build the same size block on the opposite side of the cube. At this point, the cube should look like Roux's F2B, but missing the front pairs.

3. Corner Orientation. The intended way to do this step is to first intuitively orient the D layer corners, then use the 7 algorithms from OCLL to orient the U layer corners, however you could theoretically 1-look this step using Mehta's 6CO algorithms.

4. FLFR + D layer corner. In this step, the FL & FR edges and a D layer corner are solved. The best way to do this is to first orient FLFR and stack them both on top of each other on the B face. Then you can use F2 or M' U* M moves to bring a D layer corner into the U layer, over the spot next to where it needs to go. Now you can do F* M2 F* to solve everything.

5. LSE, or Last Six Edges, is solved just like in the Roux method, except that there is a 50% chance that you will get 2 edges swapped with each other on top. If you do, then you can either use a parity algorithm that swaps 2 U layer edges and 2 U layer corners (such as a T perm or F perm), or learn twice the amount of algorithms in step 6.

6. L5C, or Last 5 Corners, solves 5 corners using 16 algorithms. Some of these are TTLL cases from ZZ-CT, and some of them are CPLL cases from PLL. Overall this step has great ergonomics and good recognition.

## Pros

• Only 24 algorithms
• Easy for beginners to learn

## Cons

• The solve is mostly intuitive, leading to a lower TPS
• It seems like Roux but with extra steps
