Orientation of the Last Layer complete The method consists of four steps: The Cross - This first stage involves solving the four edge pieces in one outer layer of the puzzle, centering around a commonly coloured centre piece. Many speedcubers usually solve the cross on the bottom side to avoid cube rotations, which slow down solve times. There are 42 standard cases for each corner-edge pair including the case where it is already solved. It can also be done intuitively. Orientation of the Last Layer OLL - This stage involves manipulating the top layer so that all the pieces therein have the same colour on top, at the expense of incorrect colours on other sides.

From beginner level to pro level, F2L is usually the step with the most room for improvement because it requires recognizing and tracking multiple pieces at once, while having quite a lot of freedom.
In other words, you know how F2L works logically. In theory, there are so many unique F2L cases that memorizing them all would be a very slow way to learn it. Once you understand the intuitive concepts from this tutorial, you should practice it until it feels somewhat natural, before moving on.
For example, you can move pieces to the top and pair them at the same time! Traditionally, watching walkthrough solves was the best way to learn advanced F2L. But in this video, the advanced concepts are structured to be easy to learn. Walkthrough solves are still useful though, as you can learn good habits and situational tricks.
Look Ahead Recommended for: Sub As you improve, look ahead will rapidly become the most important concept in all of speedsolving. Look ahead means tracking pieces as they move in order to quickly predict what to do next. Using human reaction time to recognize each separate case is rather slow, yet pros never seem to pause and look. This is all because of good look ahead, which the biggest difference between slower and faster cubers.
Once F2L cases become like muscle memory, then you can put your focus into what to solve next. The Advanced F2L Playlist has multiple videos on look ahead techniques. As much as possible, cube rotations and extra moves should be avoided. With this video and the F2L algorithm document , you can check all of your solutions against the best ones.
By predicting the first F2L pair in inspection, you reduce a pause after finishing the cross. Additionally, the harder part of the solve begins with fewer unsolved pieces and with more time to track your next F2L pair.
This is one of the most difficult skills to master competition inspection time is 15 seconds , but is also the most rewarding skill for reducing times at a high level. Next Steps Recommended for: Sub I strongly recommend watching at least a good portion of the Advanced F2L Playlist to pick up a lot of tricks and ideas to apply.
