F2L is the second step of the Fridrich method for solving the Rubik's cube. In this step 4 F2L pairs are inserted into their correct positions thus completing the first two layers. F2L is an incredibly important step of the Fridrich method that can be done intuitively without the use of algorithms. It takes a while to master, but when you eventually to get into it, it will decrease your times significantly. There are 41 basic cases that you can run into if you only consider a single pair and assume everything else to be solved.

The first two layers F2L of the Rubik's Cube are solved simultaneously rather than individually, reducing the solve time considerably. In the second step of the Fridrich method we solve the four white corner pieces and the middle layer edges attached to them. The 41 possible cases in this step can be solved intuitively but it's useful to have a table of algorithms printed on your desk for guidance. To be efficient try not to turn your cube around while solving and look ahead as much as possible.

Familiarize with the algorithms so you can do them even with your eyes closed. In the beginner's method solving the white corners and the second layer edges were two separate steps, but in this stage you should already know this.

In the advanced Fridrich method we're going to pair them in the top layer, then insert them where they belong. The simple example below demonstrates a lucky situation where the red-blue edge piece goes where it belongs while we solve the white corner.

If the red-blue corner is somewhere else, then first we need to get it to the back-top position. In the example below the white sticker is pointing upwards. First we have to put the corner and edge pieces together, and put them where they need to be. We can never affect the solved blocks! To get faster sometimes we are going to use double turns. Just a reminder that the u letter in the algorithm means the rotation of the two upper layer clockwise.

See full reference in the notation page. An intuitive approach of this situation would suggest to solve this case in the following steps: to take the two pieces to the top layer, then joining them to insert where they belong to: R U2 R' F' U2 F U' R U R'.

Let's see the possible situtations you might meet in this stage. Cases grouped by the position of the white corner and the edge that needs to be attached to it:.

The first two should be familiar from the beginner's method :. In this case we usually bring the cube to a basic case, reorienting the white corner in the first stage. Previous step Next step.

## How To Solve The Second Layer Of The Rubik's Cube (F2L)

First Two Layers , or F2L are normally the first two bottom layers of the 3x3x3 cube , or essentially all layers up until the last layer on larger cubes. The definition is a little different depending on the subject or who you are talking to. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube y' and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works. Another way to solve the 'F2L' is by building blocks, common during the first two layers of the Petrus method. There are many ways to solve the 'F2L' on a cube. A common system is using the Fridrich method first two layer approach.
