How to use this
- Each diagram looks down on the cube from above. The nine middle squares are the top face; the tabs around them are the first row of each side.
- A filled square already shows the colour you are aiming for. Find the picture that matches your cube and use that algorithm.
- If nothing matches, turn the cube a quarter at a time and look again from all four sides. The same case looks different from each angle.
- Every diagram was drawn by running the algorithm, not by copying a chart: it is what a solved cube looks like after the algorithm is played backwards.
Frequently asked questions
Q. What is the F2L 38 algorithm?
R U' R' U2 R U R' F' U' F — 10 moves in all.
Q. When do I use it?
Both are in the slot but facing wrong. 10 moves to insert. If your cube matches the picture above, this is the one.
Q. What does running it backwards do?
Playing the reverse on a solved cube produces this case, which is a convenient way to set the position up for practice.
Q. The algorithm is not working.
Turn the top layer first so the side colours line up, then start. If it still fails, rotate the cube a quarter at a time and compare the shape from all four sides.
