'''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's edges; and finally the [[last layer]]. This is the most common method for new cubers to discover on their own. More advanced LBL methods solve layers more efficiently or solve two layers at once: for example, the [[Fridrich method]] solves the [[first two layers]] simultaneously, by forming a [[cross]] of the first layer's [[edge]]s and then filling in four [[pair]]s of a [[corner]] and an [[edge]] into the so-called [[slot]]s.

Also known as LBL. Solves the cube in layers: First the bottom layer, then the middle layer, and finally the top layer or [[LL]]. As a slight advancement to basic Layer By Layer, the [[Keyhole]] method can be used to enable solving of the middle layer in fewer moves.

Done as if solving the 3x3 corners using the Layer-By-Layer method. Shorter last layer algs may be used since there are no edges to be keped in position on a 2x2. You can use any OLL you like as long as the corners are in the correct position. There are two options for the last layer in a beginner 2x2 solve:

* Orientation followed by Permutation
* Permutation followed by Orientation
