My approach to WaterRoux L7E goes as follows:

1. Orient two edges and position them at UL and UR whilst bringing either the FR edge or DR edge to the D-layer. Centers must be solved or off by an M2 in

relation to the DL corners

2. Using one OL5E algorithm, the remaining edges are oriented. Details are given in the OL5E sheet

3. Solve the remaining six edges. Details are given in the L6EP sheet

Detailed example solves:

Scramble 1: U M' U M U R2 U M2 U' r2 U2 M

My thought process:

M2 U' M' // O2E (3/3)

The M2 brought two oriented edges to UF and UB.

I then did a U' to bring them to UR and UL,

and then did an M' to align the centers, ensuring

I keep the DR edge in the D-layer.

x2 U' M' U M' U' M U x2

I see that the edge at DR is oriented, so I am

using an algorithm from the DR good set. I then

see that the visibly flipped M-slice edges are

UF and UB. Since the DR edge is at DF, I am using

the second algorithm listed for this case.

M' U' M2 U M' U2 M U2 M2

I don't see an efficient way to solve L6EP using

algorithms. I therefore solve it intuitively by

solving UL and UR with M' U' M2 U. I then solve

the M-slice with M' U2 M U2 M2.

Scramble 2: M' U M U2 R U M U' r' U2 M2

My thought process

M U M // O2E (3/3)

The M brought two oriented edges to UF and UB.

I then did a U to bring them to UR and UL,

and then did an M to align the centers, ensuring

I keep the DR edge in the D-layer.

R U M2 U' R' // OL5E (5/8)

I see that the edge at FR is oriented, so I am

using an algorithm from the FR good set. I then

see that all edges are oriented. Since the FR

edge is not visible, I can infer that it is at DB, and

I must therefore using the first algorithm listed for

U2 M2 U' M' U2 M U2 M2 U

I don't see an efficient way to solve L6EP using

algorithms. I do however notice that the edges

at DF and DB can be solved to UL and UR with

U2 M2 U'. I then solve the M-slice with M' U2 M

Scramble 3: M U M U2 M2 U' R' U M2 U' R U2 R'

My thought process

R U M' U' R' // OL5E (5/5)

I see that O2E is already solved, so I go straight

to OL5E. I see that the edge at FR is oriented, so I

am using an algorithm from the FR bad set. I then

see that the visibly flipped M-slice edges are at UF,

UB and DB. Since the FR edge is at DF, I am using

the second algorithm listed for this case.

M' U' y' // setup for L5EP (2/7)

I see that I can bring the DB edge and the white

center to the D-layer with an M'. I then recognize

I immediately recognize the Back bar and right bar

case, due to the 2x2 block at UBL. The U move

and rotation are the setup for the algorithm.

r2 U M’ U2 M U r2 U f

I executed the algorithm for the given case and

// L5EP + adjust R layer (9/16)

then fixed the R-layer with U B.
