Both Pieces Stuck in the Slot
F2L 40 — Pair in the slot — white front, edge flipped
The corner is already in the front-right slot, white sticker facing front. The edge is in the slot, front colour facing right.
Algorithm
8 moves. Hold the cube with the cross on the bottom and the slot you are filling at the front-right.
Other solutions
Same case, different move sets — some are shorter, some are kinder to your fingers, some avoid a cube rotation. Pick the one your hands like:
- yL'ULFRU2R'F'
- y'R2F'U'FURU'R
- y2LU'LUFU'F'L2
Setup / recognition
Apply this scramble to a solved cube to reach the F2L 40 case so you can practise it on demand:
One of the 41 basic cases. Category: Both Pieces Stuck in the Slot.
About this case
F2L 40 is one of the F2L cases — the pairing step of CFOP, where a white corner and its matching middle-layer edge go into a slot together. The corner is already in the front-right slot, white sticker facing front. The edge is in the slot, front colour facing right. Solve it and one of the four slots is done; four of these and the first two layers are finished, leaving only OLL and PLL.
Do not learn this as a flashcard before you understand it. Every F2L case reduces to hide the corner, set the edge, rejoin them — the algorithm above is just the fastest way to say that for this particular position.
Easy to confuse with
These cases place the pair almost identically — they are the ones you will misread under time pressure. Drill them together:
