Purpose(s):

CLL (Corners of the Last Layer) is an algorithm set that solves the last layer corners, generally on a 2x2x2 Cube, in one algorithm, or on higher order cubes when all layers below the last layer have been completely solved. Not to be confused with COLL that is an abbreviation for exactly the same approach except COLL preserves LL edge orientation on a 3x3. For a more generalized term that covers solving four corners of a layer with any other arrangement of pieces on the puzzle, CxLL is used. Both CLL and COLL fall under CxLL.

There are two different sets of CLL, the first is for 2x2, and the other that is WCLL (Watermen Corners of the Last Layer), which is used for corners first (the Waterman method) that preserves the first two layers on the 3x3. In the latter case the LL edges are solved using ELL after the CLL.


As a 2x2x2 Speedsolving Method

The first stage of CLL for the 2x2 consists of completely solving one layer of the cube (both orientation and permutation) as in the LBL method. Then, using one of 42 algorithms (2 of which are PLLs), you solve the remaining 4 corners (thus giving a 1 Look Last Layer). The algorithms needed are given in the here. This method is also named the Waterman method after the 1980s master cuber Marc Waterman from the Netherlands who was using it for his corners first method (on 3x3) back then. (The Waterman documentation).


History

CLL was first officially used by Guus Razoux Schultz (WCA) during the WC 1982.
