Layer-By-Layer, or normally only LBL is a group of methods that solves the cube in layers. In the basic, 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 the most 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 Fridrich method, one solves the first two layers simultaneously by forming a cross of the first layer edges, and then filling in four pairs of a corner and an edge into the so-called slots.

3x3x3 LBL Method

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. You can use shorter last layer algs because there are no edges that need to be kept in position on a 2x2. You can use any OLL of your choice 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
