8355 method Information about the method Proposer(s): Reheart Sheu Proposed: unknown Alt Names: none Variants: none No. Steps: 6 No. Algs: 1 to 3 Avg Moves: 100+ Purpose(s): Beginner Method

A Taiwanese beginner method invented by Reheart Sheu, similar to Layer By Layer, but using much fewer algorithms.

Procedure

• Solve the cross: (intuitive).

• Solve 3 corners: Holding the cross on D, place D-layer corners above their position in the U-layer and repeat the alg R U R' U' until placed.

• Solve 3 E-slice edges: Either using the Keyhole method or by application of the alg R' U' R' U' R' U R U R and/or its mirror L U L U L U' L' U' L' .

• Solve 3 U-layer edges: (intuitive) Hold the remaining unsolved corner+edge positions in the front-right. Using R or F', place a U-layer edge into the correct position. Now twist the U layer to replace it with an unsolved U-layer edge and undo the original R' or F move. Repeat until 3 U-layer edges are solved.

• Solve the final 2 edges: Swap the FR E-slice edge with the edge in UF without disturbing the other edges using the alg R U R' U R U R' .

• Solve the final 5 corners: Flip the cube over so that 4 of the remaining corners are in the D-layer and the other remaining corner is in the FR position of the U-layer. The corner in the U layer will be used as a 'buffer'.

1. If the corner in the buffer does not belong in the D-layer apply the alg R U R' U' once to place a D-layer corner into the buffer.
2. Twist the D-layer until the corner in the buffer position is directly above its correct position in the D-layer.
3. Repeat the alg R U R' U' until the corner in the buffer position is placed correctly in the D-layer.
4. Repeat steps 1 to 3 until only 1 unsolved corner remains in the D-layer.
5. Position the final unsolved D-layer corner under the buffer piece.
6. Repeat the alg R U R' U' until either the whole cube is solved or only 2 unsolved corners remain.
7. Rotate the whole cube so that the D-layer now contains the 2 unsolved corners, re-assigning a solved corner in the U-layer as the new buffer piece.
8. Repeat steps 2 and 3 until the cube is solved.

Example Solve

Scramble: F2 D' B2 R2 B2 D U2 L2 U' B2 F D2 B D2 R2 U' F R F' L' D'

• Cross (intuitive): R' L' F U L R2 B2

• Insert 3x D-layer corners:

1. (RUR'U')
2. y' (RUR'U')
3. y' d (RUR'U')x3

• Insert 3x E-slice edges:

1. y2 (R'U'R'U'R'URUR)
2. d2 (R'U'R'U'R'URUR)
3. y' U' (R'U'R'U'R'URUR)

• Use keyhole to place 3x U-layer edges (intuitive):

y2 U2 R U' R' . y L' U L

• Bring final U-layer edge into slot:

y' (RUR'URUR')

• Now insert it into position:

y U (L'U'LU'L'U'L)

• Flip cube over to solve final corners:

1. x2 y2 D (RUR'U')x3
2. D (RUR'U')
3. D2 (RUR'U' RUR'U' RUR'U' RUR'U' RUR'U')
4. D2 (RUR'U' RUR'U' RUR'U') D2
