LEOR (Left, EO, Right) is a method that is a mix between ZZ and Roux that allows for ergonomic steps with the mindset of speed and move count.
1. FB/LB: Build a 1x2x3 block on the left side of the cube.
2. EOStripe: Solve EO for all the other edges while solving the DFDB edges.
3. SB/RB: Build a second 1x2x3 block on the right side of the cube.
4. ZBLL: Finish the last layer in 1 step.
- Ergonomic movesets after FB.
- Low move count - similar to that of Roux.
- No rotations required.
- Steep learning curve - planning both FB and EO is very difficult.
- Difficult to smoothly solve EO and the DFDB edges at the same time.
- Corner control: it is easy to control the OCLL of the last layer which can be used to force easier ZBLL subsets.
1. L and R centers
2. 1x3x4 block on L (like in Meyer)
3. Last 4 Centers
4. Place the block on D, with the unsolved 1x1x4 in DF, then pair up any edge and place it in DF
5. Pair up the last 8 edges (the fastest way is probably with 3-2-3 edge pairing)
6. EOStripe + parity
7. Right block
9. EPLL + parity
nb. If you're solving odd layered cubes, use ZBLL instead of COLL then EPLL + parity.
1. Solve a 2x2x2 in DBL
2. Solve the FL pair
3. EODF (EOStripe but only with the DF edge)
4. Right block
2. Stripe while preserving EO
3. Right block
