Square-101 is a 3x3 method developed in the Method Development Competition August 2020. It won Best for FMC and Most Original Method.

Steps
- EOEdge
- CO setup: Two 1x2x3 blocks on U and D where the top is an oriented square and pseudopair, and the bottom is all oriented.
- Belt+CO: Insert the pseudopair and orient the remaining corners on R (27 algs + 27 mirrors = 54 total, 7 moves)
- D-pairs: Create two corner and edge pairs on the D layer in the back.
- L6CP: Permute the last 6 corners (47 algs, 10.5 moves)
- LR: UL and UR edges using only M and U moves. This is akin to step 4b in Roux.
- M-Perm: Permute the last 4 edges relative to the M slice centers, and adjust the U/D layers.
Advantages:
- Low movecount (~47 STM)
- Completely rotationless
- <R2, r2, U, D> turning is completely regripless
- Good ergonomics for pretty much the whole solve
- Efficient <MU> finish
- Two successive U and D moves, such as …U’ D’… can be done simultaneously, raising TPS (or if such sequences are considered one move, the movecount is lowered)
- Square-101 really shines at the top level. Many of the disadvantages of Square-101 can be mitigated with enough practice. Although it takes a while to get used to the recognition and look ahead, top solvers have many opportunities to influence later steps during earlier steps, and even combine steps.
Disadvantages:
- Few pieces are solved until the very end, so it can be hard to look ahead, particularly between algorithmic and intuitive steps
- Many of the steps introduce complex concepts which can be hard to get used to.
- Double turns are slower than quarter turns
- Difficult recognition
- Possibility of wrist overturning during step 2
- x-directional lookahead can be hard to get used to compared to CFOP’s y-directional lookahead (although someone who started out with Square-101 might say a similar thing about CFOP)
