This is a quick reference only. You must be familiar with the notation... You're probably best to find a more in-depth tutorial if none of this makes sense. :)
Algorithms
- Corner Algorithm: Ri Di R D
- Middle Layer (Left): Ui Li U L U F Ui Fi
- Middle Layer (Right): U R Ui Ri Ui Fi U F
- Third Layer Cross: F R U Ri Ui Fi (Blue 'L' shape Should be in upper left-hand corner, repeat if necessary)
- Third Layer Opposite Edge Flip: R U Ri U R U U Ri
- Third Layer - Edges: R U Ri U R U U Ri U (with two lined up sides (one in right hand, one opposite of you)
- Third Layer - Corners: U R Ui Li U Ri Ui L
Solving the Cube
First Layer
- Intuitively build a cross on the green face, ensuring non-corner edge pieces match center pieces of middle layer.
- Position each green corner piece below its target destination on the third layer
- With piece in place, hold cube green face up with target corner in bottom right-hand side
- Repeat Corner Algorithm until corner piece is in correct position
- Repeat for each corner until first layer is completely solved
Second Layer
- Place cube green face down, blue face up
- Find non-corner edge piece with no blue on it
- Line piece up with centre piece of middle layer
- Use either the Middle Layer (Left) or Middle Layer (Right) algorithms to place piece in the correct position in middle layer.
Third Layer
- If you do not have a blue cross on the blue face, use the Third Layer Cross algorithm.
- Need two edge pieces to line up with the same color in the middle layer.
- Place one lined up side in your right hand, the other needs to be opposite of you.
- Position any correct corner, WITHOUT spinning any sides, to the lower right hand corner of the blue face (blue is still on top).
- If no such corner exists (they are all in the wrong position) do the Third Layer - Corners algorithm from any position
- Use Corner Algorithm with target corner at bottom right of blue face until corner is flipped correctly.
- Rotate top clockwise to next unsolved corner
- Use Corner Algorithm with target corner at bottom right of blue face until corner is flipped correctly.
- Repeat for each last two steps for each unsolved corner.
