If it's oriented, use either (U R U' R') or (U' L' U L) to insert it, depending on which side the pair is on. Look at the edge directly next to the F2L pair corner (the edge that isn't part of the pair, obviously). Place the corner of the F2L pair directly above the slot the pair wants to go into. The most basic way of edge control using the last F2L pair is as follows:Īfter the pair has been built, don't insert it yet. And EO can be shortened using good edge control. Compare that to OLL/PLL, which has 57 OLL cases and 21 PLL cases, for a total of 78 algorithms.ĮO/COLL/EP is definitely a viable option for solving last layer compared to OLL/PLL, and requires knowing less algorithms.

There are 3 EO cases, 42 COLL cases, and 4 EP cases. The big thing, however, is that using EO/COLL/EP over OLL/PLL requires knowing less algorithms.

However, edge orientation is a very fast step, with 2 of the cases only requiring a fast 6 move algorithm, and the 3rd case being able to be skipped with edge control when inserting your final F2L pair. If you fully relied on just COLL, it would require 3 steps to solve the last layer (edge orientation, COLL, edge permutation). If your edges are oriented (ie you have a "cross" on the top face of the cube), you can use a COLL algorithm to simultaneously orient and permute the corners in one algorithm, so that after all that's left is edge permutation. PLL is permutation of the last layer, switching the pieces around in the last layer to solve the last step of the cube in one algorithm.ĬOLL is Corners Of the Last Layer.

OLL is orientation of the last layer, making the top face one color in one algorithm.

Let me just start this off by saying I haven't yet learned COLL, and I know full OLL and full PLL.įor those who don't know, OLL and PLL are 2 last layer algorithm sets.
