Easy Cases
The PairMove the pair forward, then make room and slot it in.
|
Split PairFront 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, PerpendicularFront 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, ParallelFront 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
These involve a quarter-turn if the white face of the front half faces down when hidden in the corner, and a half-turn if it faces to the side.
Mnemonic: The white face is a foot dragging behind, slowing rotation down to a quarter-turn.
Crossed Split PairSplit 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.

Twisted PairPair, 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.
Back right slot open: R' U2 R2 U R' | ||||||||||||||||
Twisted Sideways PairFront 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
These have an opposite pattern to the above: If the white face is down, it's a half-turn.
Mnemonic: Each of these is a “slingshot”; flinging something sideways (i.e. the front, or white part, isn't forward) won't send it as far.
Sideways PairFront half faces sideways, back half similarly colored (on top). Lean back, then move backward to cut. Return, forming a split pair.
Front left slot open: U (R U' R') D (R U' R') D' Back right slot open: U' (R' U R U') (R U R')
|
Dead Twisted PairFront 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 OppositeFront half faces upward, back half is opposite its top color. Move the back half to its own color, hide it in the far corner, then move the top half to make the pair.
|
Dead Split Pair, Back AdjacentFront 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.
|
Weird
Dead PairFront half faces upward, back half attached and similarly colored (on the front). Just … just do as the man says.
