3-style
Blindfolded, the pieces are put back three at a time from a fixed spot, the buffer: UBR for corners, DF for edges. Each case is a pair of Speffz letters and is solved by a commutator. The cases load group by group.

The commutators are not given as optimal: the page gives the length of each.
The application's 3-style catalog: computed commutators and commutators published by the community (the BLDDB database), all checked again.
How to read this page
- Each case is drawn on the cube's net: the top above the front face, then left, front, right and back, the bottom below. The buffer is circled, the targets carry their letter.
- Colours of the cube in the application; the stickers the case does not move are faded.
- 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 commutators are sorted from the easiest to the hardest to execute (ease score, lower is easier); the bracket writing gives their structure.
- "Play" starts from the case (the inverse of the algorithm applied to the solved cube) and runs the algorithm on the 3D cube.
- Speffz letters. A pair reads buffer, then first target, then second target: the buffer piece goes to the first target, that one to the second, and the second comes back to the buffer.
- Twists: the corners are numbered 1 ULB, 2 UBR, 3 URF, 4 UFL, 5 DLF, 6 DFR, 7 DRB, 8 DBL; "i" marks the other direction. A flipped edge is written as its letter doubled.
