Edge Already in the Slot
F2L 25 — Right up · edge in slot (correct)
The corner sits above the slot, the right colour on top and white facing right. The edge is in the slot, front colour facing front.
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:
- U'RU2R'URUR'
- yUL'ULU2L'UL
Setup / recognition
Apply this scramble to a solved cube to reach the F2L 25 case so you can practise it on demand:

About this case
F2L 25 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 above the slot, the right colour on top and white facing right. The edge is in the slot, front colour facing front. 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:
