Both on Top — U Stickers Match
F2L 23 — Front up · edge front, front on top
The corner sits above the slot, the front colour on top and white facing front. The edge sits front, the front colour on top.
Algorithm
7 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:
- y2f'LfU2LUL'
- y'R2FRF'RU2R'UR
- yL'ULy'U2RUR'
- U'R'URU'RUR'
Setup / recognition
Apply this scramble to a solved cube to reach the F2L 23 case so you can practise it on demand:
One of the 41 basic cases. Category: Both on Top — U Stickers Match.
About this case
F2L 23 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 front colour on top and white facing front. The edge sits front, the front colour on top. 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:
