TCLL (2x2x2) method
Information about the method
Proposer(s): Robert Yau

Christopher Olson

Proposed: 2013
Alt Names: none
Variants: LBL, CLL, TCMLL
No. Steps: 2
No. Algs: 128 (86 for only TCLL)
Avg Moves: <15
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

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
