The **Zipper Method** is a speedsolving method created by Justin Taylor in 2017, several months after development of the Ribbon Method. The method was created as a Two-Look solution for the Last Slot and Last Layer without preorienting edges and maintaining a manageable algorithm count. This allows great versatility in approach for the F2L, along with a smooth transition into LSLL. Additionally, this method has a very fast LS+LL, as it combines the well-established OLLCP step with L5E, a 2gen, low algorithm step with easy recognition and execution. The method retains every ergonomic advantage of CFOP, while containing one fewer "look" in the solve and saving an average of 9 moves with a CFOP-like approach to F2L. Zipper can either be used as a standalone method, or in conjunction with other CFOP subsets whenever a corner solves itself during F2L.

## The Steps

This is the most distinctive part of the Zipper Method. Taking an average of 6 moves and no more than 9 moves, this step solves the Cross on the bottom and any first layer corner, forming a "fish" on the bottom layer. This slot is referred to as the Zipper Slot. Technically, the Zipper Slot can be solved at any point during the F2L, such as using Multislotting to insert the lone corner during the solving of another slot. This is done whenever is easiest during F2L execution.**Cross + 1 Corner (Fish):**There are three remaining F2L slots to be solved. Typically, this is done using pairs as in CFOP. However, any approach can be taken to solve the cube up to F2L-1 Edge. First Block, carried over from Roux, may be used in conjunction with <RrUM> for the rest of F2L to provide an efficient and rotationless option to finish F2L.**F2L:**This is the first algorithm set of the Zipper Method. There are 331 algorithms to orient the last layer of the cube and permute the remaining corners in an average of 11 moves with as few as 6.

In order to correctly use OLLCP in Zipper, the orientation of the edge in the Zipper Slot must be accounted for.
