ZZF2L case finder

Tap the facelet where the white sticker of your corner is, then tap where the green-red edge is. White stays on the bottom.

All four slots start open, like right after EOCross. Solve a scramble's EOCross in the EO trainer tab and it lands here tracked. Solve a pair on your cube, press Solved, next pair, and it's marked done.

The principles behind the cases
  1. EO is done, so no F/B quarter turns. Edge orientation stops being a variable: a top-layer edge always has its front/back colour facing up, and a slotted edge always has it facing front/back. You only ever need to know where the edge is.
  2. A case is corner orientation first, edge position second. Three corner states: white facing front/back, white facing right/left, white facing up (the awkward one).
  3. There are only two inserts. For the front-right pair: R U R' (white on the right, edge at the back) and R U' R' (white on the front, edge on the right). Every other alg is "get to one of these pictures, then do it". The other slots use the same two moves mirrored.
  4. White up needs a tilt. Either split and re-pair with an R U' R' / R U2 R' style move, or use F2, which flips white from up to down while keeping EO.
  5. A solved corner is a closed door (keyhole cases). Lift it out and re-pair, crack it with an F conjugate, or rotate a helper slot underneath with D.
  6. Piece in the wrong slot: pop, then insert. Pop with that slot's own moves (L' U L for front-left, L U L' for back-left, R' U R for back-right, and so on), chosen so the piece lands ready for a basic insert. Both in wrong slots is two pops plus an insert.
  7. Every D, F2, wide or F move is a conjugate: set up, do RU moves, undo. D rotates a helper slot under the R layer; wide u/r shifts the middle slice so a half-turn shuffle swaps pieces between slots.
  8. The four slots are mirrors of each other, so learn one deeply and the rest are the same hand motions reflected. Within a slot, the 12 top-layer cases plus the three pop moves cover almost everything.
