## COLL

These are the 40 corner cases for the last layer when the edge orientation is correct and the algorithms I use for them. Note that I do not use COLL for the Sune and Antisune cases, so I have not included those algorithms here. These algorithms appear EXACTLY as I perform them when I am solving the last layer, in speedcubing notation with rotations included in the algorithm. It should be noted that these are the algorithms that I find easiest to perform. However, you may find other algorithms better-suited for your own hands, so it is recommended to try many different algorithms for the same situation to find which one works best for your own style of cubing.

In each diagram, yellow is the color of the upper face. A yellow "bar" indicates that the last layer color is facing that direction in that location. Another color denotes that a particular piece is not oriented correctly. If a sticker is colored grey, it is not important for recognition. For recognition, we will consider red the front, orange the back, green the right, and blue the left. Mostly we will just be looking to see which pieces match or are opposite from each other, so the exact color is irrelevant. We're just looking at how pieces are arranged relative to each other.

In each diagram, yellow is the color of the upper face. A yellow "bar" indicates that the last layer color is facing that direction in that location. Grey denotes that a particular piece is not oriented correctly.

### The "U" Case

# | Diagram | Algorithm | Comments |

01 | [U'] (R' U' R F) (R2 D') (R U R' D) (R2 U') F' |
||

02 | (R' U2) (R F' R' F) U2 (F' R F) |
||

03 | F (R U' R' U) (R U R' U) (R U' R' F') |
||

04 | (R' U') (R U') (R' U2) (R2' U R' U) (R U2' R') |
This is the two-gen case. It is just two Sune variants. | |

05 | (R2 D') (R U2) (R' D) (R U2 R) |
||

06 | [U2] (R2' D) (R' U2) (R D') (R' U2 R') |
This is my standard alg for this
OLL. It is the mirror of Case #05. |

### The "T" Case

# | Diagram | Algorithm | Comments |

07 | (R U2) (R' U' R U') (R2' U2) (R U R' U R) |
This is the two-gen case. It is just two Sune variants. | |

08 | (R' U R2' D) (Rw' U2) (Rw D') (R2 U' R) |
||

09 | [U2] F (R U R' U') (R U' R' U') (R U R') F' |
||

10 | (R' U) (R U2') L' (R' U R U') L |
||

11 | [U'] (Rw U) (R' U') (L' U) (Lw F') |
This is the standard OLL case that I use. | |

12 | [U] (Lw' U') (L U) (R U') (Rw' F) |
This is just the mirror of Case #11. |

### The "L" Case (Triple Sune)

# | Diagram | Algorithm | Comments |

13 | [U] (R' U2 R' D') (R U2') (R' D R2) |
||

14 | [U2] (R U2 R D) (R' U2) (R D' R2') |
||

15 | (R U2) (R' U' R U) (R' U' R U) (R' U') (R U' R') |
This case is equivalent to performing the Sune three times. | |

16 | [U2] (R' F) (R B') (R' F') (R B) |
||

17 | [U2] x (U R U') (L U) (R U' Rw') |
||

18 | (L' U2) (R U') (R' U2) L (R U' R') |

### The "Pi" Case (Bruno)

# | Diagram | Algorithm | Comments |

31 | [U] (R U') (L' U) (R' U) (L U) (L' U L) |
||

32 | [U2] (F U) (R U' R' U) (R U2 R' U') (R U R' F') |
||

33 | [U] (R U2') (R2' U') (R2 U') (R2' U2' R) |
This is the two-gen case. I use the same alg that I use for the standard OLL case. | |

34 | [U] F (R2 U') (R U') (R U') (R' U2) (R' U R2) F' |
||

35 | (R' U2) (R U R' U) (R2 U') (Rw' F) (R' F' Rw) |

36 | [U'] (R' F2) (R U2) (R U2) (R' F2) (U' R U' R') |
This is just the mirror of Case #35. |

### The "H" Case (Double Sune)

# | Diagram | Algorithm | Comments |

37 | F (R U R' U') (R U R' U') (R U R' U') F' |
This is just F (triple sexy) F'. | |

38 | (R U2) (R' U') (R U R' U') (R U' R') |
This is the two-gen case. It's just the double antisune (or you can do y and perform a double sune). | |

39 | [U'] (R U R' U) (R U) (Rw' F) (R' F' Rw) |
||

40 | [U] F (R U' R' U) (R U2 R' U') (R U R' U') F' |
