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 40 for the CLL.


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


  • 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


  • 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'
