Contents
Base 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.
Back Right Slot Open: R' U R2 U R' |
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. Make the pair in the back, then place it before restoring.
|
Weird
Dead PairFront half faces upward, back half attached and similarly colored (on the front). Just … just do as the man says.
|
Corner In Place
Prodigal SonFront half is correct; back half is on the side matching its outward color. Move the back half away, flip the front half up, then return the back half and bring together the pair.
|
Posing OutwardBack half is on its own side; front half is in place but facing the other side. Hide the back half in the corner, then bring the front half toward it to make the pair in the corner.
| ||||||||||||||||||||
Posing ForwardBack half is on its own side; front half is in place but facing that same side. Hide the back half in the far corner, move the front half away, then restore to form a split pair.
|
Edge In Place
Upward PairPair in its own corner, facing upward. Extract the pair and place it.
|
Upward Twisted PairTwisted Pair in its own corner, facing upward. Extract the pair, splitting it while restoring, forming Posing Forward.
| ||||||||||||||||
Standing PairBack half correct; front half facing outward. Split the pair by moving the front backward; hide the front in the corner, then move to form the pair.
|
Standing Twisted PairBack half in place but flipped; front half facing outward. Split the pair by moving the front forward a half-turn; move the back half out the other way, then clear that face, making a split pair.
|
Both In Place
Downward PairSolved. |
Downward Twisted PairLike Downward Pair, but twisted. Extract the twisted pair.
| ||||||||||||||||
Hanging Twisted PairBack is correct; front is in place but facing outward. Turn the pair so that white faces up, then split it while restoring, forming a twisted split pair.
|
Hanging PairBack is in place but flipped; front is in place but facing outward. Turn the pair so that white faces up, then split it while restoring, forming a crossed split pair.
Becomes Crossed Split Pair. |
