PLL is the last step of the Fridrich Method. After you finish OLL, pieces on the last layer will need to be permuted moved around. Find out which diagram indicates how you need to move them around, and apply the algorithm. Then one of the diagrams should match what you have. You need all of the 21 algorithms below to solve this stage in a single step. However, if you are willing to do it in two steps instead, you can use what is called the 2look PLL.

PLL is the last step of the Fridrich Method. After you finish OLL, pieces on the last layer will need to be permuted moved around. Find out which diagram indicates how you need to move them around, and apply the algorithm. Then one of the diagrams should match what you have.
You need all of the 21 algorithms below to solve this stage in a single step. However, if you are willing to do it in two steps instead, you can use what is called the 2look PLL.
You then only have to learn 6 of them at the expense of speed obviously. Also, here is a printable sheet of all cases and solutions for reference, in pdf format Thank you Husayn for making and sending me this sheet. This is a program that I wrote that helps you practice PLLs.
It generates a random PLL, and then it times how quickly you can perform it. It keeps track of all of this, gives you averages, etc. To rotate any of the PLL's in the program, just rotate the image in the folder. The program just loads these images when it starts.
For full description go here. Difficulty to Learn at each row assumes that you already know all algorithms in all rows above it.
I highlited and grouped the notation that I thought would best help you memorize the algorithms, and i also color coded some very frequent triggers. Also, algorithms that are very close to each other are grouped by background color in the "Difficulty to Learn" column.
This excel sheet link may help you with pattern recognition for the PLLs. Thank you RiDo for making this! I highlighted the differences. There is simply one extra U, so instead of R' U R' in the beginning you have R' U U R' or R' U2 R' , and then you have to undo that U at the end of the algorithm, so there is an extra U' that pops in from nowhere near the end of the algorithm.

Forget printable sheets! Also, here is a printable sheet of all cases and solutions for reference, in pdf format Thank you Husayn for making and sending me this sheet PLL Trainer This is a program that I wrote that helps you practice PLLs.
You can go to Bob's PLL page and watch his videos on how he executes each algorithm with fingertricks, because many of his and mine are indeed the same, or very similar. The algorithm has a little bit of a symmetry to it.
But I know that many of my friends do it differently. Find what suits you best, it is not too hard or long. This is the exact same type of motion you do in A a. If you memorized it by motions instead of notation, you should be able to do this one without too many problems. Note how the algorithm is basically always R and then U' U U U' in that symmetrical order accompanying the R, and lastly R' and fix up rest by aligning pieces.
A very easy to remember algorithm. Note how the M2's always alternate, and in between you simply have just U, U2, U. I find it easy to learn this algorithm by tracking F2L pairs around the cube.
RUR'U' takes out a pair. R'F hides it and takes the other pair out to the top layer. R2U'R' aligns this pair with the whites and hides that pair.
Now all the pairs are hidden from the top layer. Now we do U' on the Top Layer. So just do RUR'F' and then start doing the T permutation above until you see that the cube is solved!
Again I find it helpful to see how F2L pairs move around for this algorithm. Now again as before, all F2L is again intact, but slightly messed up. The result will leave you with an OLL, which after when you fix using the appropritate algorithm, you will be left with Ypermutation at the end. Again for this one I find it easiest to track an F2L pair. Remember the first part using just notation because it is easy. After R'F you have an F2L pair on the bottom.
Then you do RUR'U' trigger. This is just the reflection of the above. You need to do the above, but using the left hand instead of the right hand.
You will be able to mirror the R permutation to your left hand after about a weeks practice of doing it with your right hand. When it becomes a little bit of muscle memory for you it should be really easy to mirror the algorithm with the left hand.
So if you can't do it right away, just wait a little more and get a little more comfortable with R b. The second algorithm is an alternative that I sometime like to do because it involves the faster right hand instead. I don't really have a great way to memorize this and thats why I rated this as a hard algorithm. I kind of just did it until I had it in my muscle memory.
RUR' takes out a pair. Then rotate the cube, and now the fun part starts. I highleted the R rotations so that you can see the pattern better. Notice in particular how the U turns are.
It has a very nice symmetry to it. The R's I remember as follows: Since in execution I perfrom the R2 as RR in clockwise motion , I see them as R clockwise twice, and then R counterclockwise twice, and the final R2 is just to finish up the algorithm. You are welcome to come up with better memory techniques for this things.
I know a couple of friends, each with different ways of remembering these G perms This is similar. First take out the pair that is right under the aligned 2x1x1 block, as in G d , and then rotate the cube, and do a similar pattern.
See how there is a symmetry to the U's again? This is simply G d inverted. But I find it useless to remember it like that. This is like a completely new algorithm for me. Note the still distinct pattern to the U's. And also R's. Remember it as you wish. Similar to the H permutation, I find this easy to remember, and I saw some people executing it extremely quickly.
The last part RLU just simply restores all yellows and I find it very easy to see it visually. This algorithm has a nice symmetry to it, as highlighted. Some people fund the second one faster to execute. To memorize this, track the corner in UBR. As you do R'UL', it will travel along a U on the top layer of the cube. Then do U2, and then restore yellows by doing RU'L. Then repeat that whole thing again. I hate executing this algorithm. Its a good thing that it rarely ever comes up.
Orientation of Last Layer (OLL)
OLL is the 3rd step of the Fridrich Method. Right after you finish the F2L, your cube will look like one of the following cases on top. After performing the algorithm, your cube should be all yellow on top. You need all of the 57 algorithms below to solve this stage in a single step. However, if you are willing to do it in two steps instead, you can use what is called the 2look OLL. You then only have to learn 9 of them at the expense of speed obviously.
