Expert — Flipped Edge, Corner Adjacent
F2L E15 — Down up back-right slot · edge in slot (flipped)
The corner sits in back-right slot, white facing down. The edge is in the slot, front colour facing right.
Algorithm
9 moves. Hold the cube with the cross on the bottom and the slot you are filling at the front-right. Heads up: this solution disturbs another slot on the way, so only use it while that slot is still empty.
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:
- R'U'RF'U'FURU'R'
- yRU'R'M'U'L'UlL'UL
Setup / recognition
Apply this scramble to a solved cube to reach the F2L E15 case so you can practise it on demand:
Expert — both pieces are down in slots. Category: Expert — Flipped Edge, Corner Adjacent.
About this case
F2L E15 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 sits in back-right slot, white facing down. 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:
