Previous cube state -> CLL (2x2x2) step -> Next cube state


The CLL (2x2x2) step is the step between the Previous cube state and the Next cube state.

CLL, short for Corners of the Last Layer, is a step that solves the last layer corners, generally on a 2x2x2 Cube in one algorithm. Not to be confused with COLL that is an abbreviation for exactly the same approach except COLL preserves LL edge orientation on a 3x3x3.

There are two different sets of CLL, the first is for 2x2x2 cube, and the other that is used for corners first (the Waterman method) that preserves the first two layers on the 3x3x3 cube. 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 2x2x2 consists of completely solving one layer of the cube (both orientation and permutation) as in the Layer-By-Layer method. Then, using one of 42 algorithms (2 of which are PLLs), you solve the remaining orientation and permutation of the last layer (thus giving a 1 Look Last Layer). The algorithms needed are given in the CxLL pages. 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 3x3x3) back then (the Waterman documentation).


History

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