Purpose(s):

TCLL or Twisty Corners of Last Layer is an advanced 2x2 method proposed in 2013 by Robert Yau and Chris Olson based off a study into RoFL (ROtten First Layer) by Stefan Pochmann. It is efficient and is very good for those who can 1-look their 2x2 solves and cancel into algorithms. It can be divided into 3 subsets: regular CLL, TCLL- (where the misoriented corner in DR faces to the right) and TCLL+ (where the corner faces to the front). There are 43 algorithms for each TCLL set and 42 for the CLL.

Steps

  1. Solve a layer (one corner can be twisted in place)
  2. TCLL

TCMLL

For the Roux and WaterRoux methods, TCMLL algorithms which preserve the first two blocks have been developed by Neuro.

Pros

  • Can easily be 1-looked in almost all cases fairly easily.
  • Lots of cancellations can be formed between the layer and the algorithm
  • Building a layer with a twisted corner is much shorter than building a full layer
  • Can have ridiculously easy solves

Cons

  • It is not generally recommended to use TCLL as a stand alone method
  • Beginners may find it difficult to 1-look solves and take advantage of the cancellations
  • Approximately 2 Times more algorithms than CLL, EG-1 or EG-2

Example Solves

  1. R' F' R2 F R' U' F2 R' U'
    • x2 y' (Canceling moves instead of doing U2 R U2 R) U2 F R F' R U
  2. F' R U' R' U F2 R' U2 R2
    • y' L' U' L' F' L F U2 L' U2 L
  3. U R' F R' U2 R F' R U'
    • z2 U' (Canceling moves instead of doing R U' R') R U2 R' U2 R U2 R' U
  4. R' F U R F2 R U' R2 U
    • x L2 U2 R U R' U' R U2 R' F' R U R' F'
  5. U2 F2 U' F U' F' R' F' U2
    • x' y' U F2 R U2 R' U R' F R F' R U' R'
  6. U R2 F' U R U2 R F2 U2
    • x' U2 R y U' F R' F' R2 U R'
  7. U2 F' R' U' F2 U' R2 U R2
    • x2 U F' R F' R U R2 U' R U R'
