# LEOR

 LEOR method Information about the method Proposer(s): Arc, Pyjam Proposed: 2017 Alt Names: LEOR-a Variants: LEOR-b, EOMR No. Steps: 4 No. Algs: 4-497 Avg Moves: 48 with ZBLL Purpose(s):

LEOR (Left block, EOStripe, Right block) is a method which could be seen as a mix between ZZ and Roux, although due to effectively solving an EO223 in the beginning, it also shares similarities with Petrus.

LEOR allows for ergonomic steps while also offering a low movecount.

## Steps

1. FB/LB: Build a 1x2x3 Block on the left side of the cube.
2. EOStripe: Orient all edges while simultaneously solving DF and DB.
3. SB/RB: Build a second 1x2x3 block on the right side of the cube.
4. ZBLL: Finish the last layer in one step using one of 493 algorithms.

## Pros

• Ergonomic movesets after FB, especially for OH.
• Low movecount - similar to that of Roux.
• No rotations required.

## Cons

• Steep learning curve - planning both FB and EO is very difficult.
• Difficult to smoothly and efficiently 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.

## Big Cubes

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
8. COLL
9. EPLL + parity

nb. If you're solving odd layered cubes, use ZBLL instead of COLL then EPLL + parity.

## Variants

LEOR-b

1. Solve a 2x2x2 in DBL
2. Solve the FL pair
3. EODF (EOStripe but only with the DF edge)
4. Right block
5. ZBLL

EOMR

1. FBEO
2. Stripe while preserving EO
3. Right block
4. ZBLL

Due to how similar ZZ and LEOR are, most variants of ZZ can also be applied to LEOR.
