'''Layer-By-Layer''', or normally only '''LBL''' is a group of [[method]]s that solves the [[cube]] in layers. In the basic, [[3x3x3 beginner methods#Layer By Layer|beginner LBL method]], the solver finishes the layers one at a time: the [[first layer]] edges, then corners, then the second layer edges, and finally the [[last layer]]. This is a common method for new cubers to discover on their own. In more advanced LBL methods, you solve layers more efficiently or solve two layers at once. For example, in the [[CFOP method]], one solves the [[first two layers]] simultaneously by forming a [[cross]] of the first layer [[edge]]s, and then filling in four [[pair]]s of a [[corner]] and an [[edge]] into the so-called [[slot]]s.


There are many 3x3x3 methods that fully or partially use a LBL approach, including [[CFOP]], the method used by most top speedcubers in the world. Three examples of how cubers might approach LBL:  

===Beginner 3x3x3 LBL===

With this method, the novice cuber truly completes each layer one after the other, using few algorithms (but taking perhaps over 100 moves). This is one of the most popular beginners' methods in existence.

* ( [[Daisy]] )
* Bottom layer: [[Corners XG]] ([[Cross]] plus Corners)
* Middle Layer:  Insert the 4 middle layer edges (each edge is inserted individually)
* [[4-Look Last Layer]], sometimes actually more like 8-looks by re-using algorithms

===Intermediate 3x3x3 LBL===
At this stage the cuber may develop strategies such as keyhole to reduce middle layer moves, as well as learning further last layer algorithms. 

* [[Cross]]
* [[Keyhole]] F2L
* [[4-Look Last Layer]]

===Advanced 3x3x3 LBL===
The advanced LBL cuber often uses [[CFOP]], employing fast, intuitive F2L techniques and learning many more last layer algorithms to reduce moves and improve speed further. 
* [[Cross]]
* [[F2L]]
* [[OLL]]
* [[PLL]]

As if you are solving the 3x3 using the Layer-By-Layer method.

Do the bottom layer first, then [[OLL (2x2x2)]], and last [[PLL (2x2x2)]].
