Easy Cases

The Pair

Move the pair forward, then make room and slot it in.

Split Pair

F2L03.png F2L04.png

Front half faces forward, would be correctly placed by turning downward. Back half is parallel to forward direction and oppositely colored.

Bring the pair together, then move it forward and return.

Reposition Edge

Twisted Split Pair, Perpendicular

F2L05.png F2L06.png

Front half faces forward, back half lies perpendicular and is similarly colored.

Move backward, then hide the front half in the corner and move the back half in to make the pair.

Twisted Split Pair, Parallel

F2L07.png F2L08.png

Front half faces forward, back half lies parallel and is similarly colored.

Move backward, then hide the front half in the corner and move the back half in (by a half-turn) to make the pair.

Reposition Edge and Flip Corner

Crossed Split Pair

F2L09.png F2L10.png

Split pair, but back half lies perpendicular.

Move forward, then hide the front in the corner, then move the back half into position for the split pair.

Back Right Slot Open: R' U R2 U R'

Twisted Pair

Pair, but the back half is twisted.

Move backward, then hide the front half in the corner and move the back half into position (by a half-turn) for a split pair.

Twisted Sideways Pair

F2L13.png F2L14.png

Front half faces sideways, back half oppositely colored. Each side faces "correctly."

Move backward, hide the front half in the corner, and position the back half for a split pair.

Split Pair by Going Over

Sideways Pair

F2L15.png F2L16.png

Front half faces sideways, back half similarly colored (on top).

Lean back, then move backward to cut. Return, forming a split pair.

Dead Twisted Pair

F2L17.png F2L18.png

Front half faces upward, back half attached on its own side and oppositely colored.

Lean back, then move backward a half-turn to cut. Return, forming a split pair.

Pair Made on Side

Dead Split Pair, Back Opposite

F2L19.png F2L20.png

Front half faces upward, back half is opposite its top color.

Move the back half to its own color, hide it in the corner, then move the top half to make the pair.

Dead Split Pair, Back Adjacent

F2L21.png F2L22.png

Front half faces upward, back half is near its top color.

Rotate the front half parallel to the back half. Clear that face, then return, forming a split pair.
