OLS
The pair is in the top layer or in its slot, either way round; one algorithm inserts it and orients the whole last layer. 8,111 cases, the 57 OLLs included, sorted into families (n corners and m edges of the last layer already oriented on top) then groups. The cases load family by family.
8,111 cases · 72,663 algorithms
Proven optimum for every case.

How to read this page
- Each case is seen at three quarters: top, front and right faces, plus the top layer's back and left stickers as flat strips.
- 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 available optimal algorithm comes first, then the others by increasing ease score. When no optimal writing is available, all algorithms are ranked by this score (lower is easier).
- "Play" starts from a position of the case and runs the algorithm to the set’s goal. Usually, the starting position is obtained by running the algorithm backwards from the solved puzzle. For a partial goal, the player may start from a representative position of the case in the application; the puzzle is not necessarily fully solved at the end.
