ZBLL
When the last-layer edges are oriented, one algorithm solves the whole layer. 472 cases, sorted by corner shape (T, U, L, H, Pi, S, AS); the 21 PLLs are not part of it. The cases load group by group.

How to read this page
- Each case is seen from above: the top face in the middle, the top layer's stickers on its sides, the front face at the bottom.
- Colours: yellow on top, blue in front, red on the right. Grey marks what the case does not look at.
- Lengths in HTM: a face turn or a wide turn counts 1, a slice 2, a rotation 0. The "setup" (often a U turn) presents the cube as drawn and does not count.
- In each case, the best optimal algorithm comes first, then the others from the easiest to the hardest to execute (ease score, lower is easier).
- "Play" starts from the case (the inverse of the algorithm applied to the solved cube) and runs the algorithm on the 3D cube.
