3x3 · F2L
3x3 F2L 4 algorithm
3x3 F2L 4: corner at UFR, edge at UB. Learn the 3-turn algorithm with sticker directions and execution notes.
Insert the target corner–edge pair while keeping the cross and the other completed slots intact.
F2L 4 belongs to the Free Pairs group in F2L.
Recognize this starting position
For the front-right target slot in this training state, the DFR corner is at UFR and the FR edge is at UB. Corner sticker directions are R→U, F→F, D→R; edge sticker directions are F→U, R→B. Each arrow reads color reference face → current facing direction.

R U R'
The opening is R U R'; the final segment is R U R'. This version contains 3 face, wide, or slice turns and no whole-puzzle rotations.
