Step 6 of 6

The last four edges

What you should end up with

The last step: the four edges and the centres of the middle slice. M and U2 are nearly always enough, so nothing you built gets disturbed. The cube is solved. Guides call this step 4c, or L4E.

How to do it

If the top centre is white, do M2: yellow has to be on top. This makes the cases easier to recognise.
Look at the four middle-slice edges and compare their stickers with the centres next to them. An edge is in place when both its colours match the centres. Tilt the cube to see the bottom back one.
If one edge is in place, also find the one where neither colour matches. That pair names your case. If all four are in place, the cube is solved.

One edge in place

In place at the bottom front Neither colour matches on the top front edge.

U2 M U2 M'

In place at the bottom front Neither colour matches on the bottom back edge.

M U2 M' U2

No edge in place

Green and blue are swapped Yellow and white are right, but the front and back colours have swapped.

Everything is swapped No colour matches on any edge. E2 takes the blocks apart for a moment, and the second E2 brings them back. Without E, but slower: U2 M' U2 M2 U2 M' U2.

Tips

›Once you are comfortable, you can skip the first M2 and recognise cases straight away. Steps 4 and 5 are also often joined into one: that is called EOLR.

The cube is solved!

Now time yourself on the timer. Once the nine corner formulas feel familiar, move on to full CMLL: one look and one formula instead of two.
