41 cases

F2L — first two layers

All 41 ways a corner and its edge can be arranged, and the most efficient way to pair and insert each.

F2L replaces the beginner method's "corners then edges" with "pair them up, then insert the pair". It is the single biggest speed gain available, and most of it can be worked out rather than memorised — the algorithms here are what your hands settle into once you understand the idea. Learn to see the pair, not the sequence.

From intermediate

Corner in the top, edge in the top 24

Corner facing right, edge at the back

F2L 1
Not started Intermediate 2/75 3 moves

F2L 2
Not started Intermediate 2/75 3 moves

F2L 3
Not started Intermediate 2/75 4 moves
URU'R'

Corner and edge are already side by side at the front-right of the top layer, their side colours making a matching block down the right-hand face, and the corner’s cross colour points at you.

Joined pair, corner facing right

F2L 4
Not started Intermediate 2/75 4 moves
U'F'UF

Corner and edge are side by side along the front of the top layer, both showing the front colour on the front face, and the corner’s cross colour points out to the right.

F2L 5
Not started Intermediate 2/75 7 moves
RU'R'U2F'U'F

Corner above the slot with the cross colour to the right, edge immediately beside it on the right but with its side colour on top, so the two colours next to each other do not match.

F2L 6
Not started Intermediate 2/75 7 moves

UF'UFU'F'U'F

Corner above the slot with the cross colour facing you, and the edge directly in front of it showing its front colour on the front face — so the front face has two different colours stacked on it.
