The 57 OLL Cases

Source:

Moves in BOLD are my current favorites.

Probabilities:

  • BLUE — p=1/54
  • GREEN — p=1/108
  • RED — p=1/216

Triggers:

  • (L F' L' F), (R' F R F')
  • (L' U' L U'), (R U R' U)
  • (L' U' L U), (R U R' U')

All Edges Flipped Correctly

BB: For most of these cases, I instead use some COLL cases, which orients AND permutes the corners, so 1/12 of the time you will be left with a solved cube and the other 11/12 of the time you will be left with an easy (fast) cycle of edges.

Antisune
setup / gives: OCLL7

[y] R U2 R' U' R U' R' (BM,BB,VC)

BB:This is just the inverse of the Sune, called the Antisune.

(R' U' R U' R' U2 R) (AK)

setup / gives: OCLL6

[y] (R U R' U) R U2 R' (BM,BB,VC)

BB:This is the Sune. Your right hand should never come off of the cube during the execution at any time.

[y] (R U2) (R' U' R U R' U' R U' R') (BB)

BB:This is a very easy case. This can be performed as a double Sune or double Antisune. I recommend learning the COLL cases for this one as well since there are only four cases.

[y] F (R U R' U') (R U R' U') (R U R' U') F' (BM,VC)
(R' U' R) U' (R' U R) U' (R' U2 R) (BM)

setup / gives: self

R U'2 R'2 U' R2 U' R'2 U2 R (BB,BM,VC)

BB:The execution of this algorithm is pretty neat. The turns should alternate in direction so that they can be performed by the right hand without letting go of the cube. The left hand holds the cube and makes the U' turns.
Note: new grip: Thumb on D face, first U'2 with right hand, then all other U moves with left hand).
Note: grip 1: Thumb on U face, perform U'² with right ring and middle finger. The last is done with RH).
Note: grip 2: Thumb on F face, perform U'² with the left hand.

[f (R U R' U') f'] [F (R U R' U') F'] (BM)

Note:Interesting algo and my current favorite! Do f' F as S' instead, blocking the F face with left index after the 1st U'. But maybe f' F is faster?

OCLL4 - 24
setup: OCLL5 / gives: OCLL5

[y'] (l' U') (L U) (R U') (r' F) (BB)

BB:This one is pretty fast. The only problem is that you have to alternate hands a couple times. I recommend being able to do the mirror of this case as well.

[y] (r U R' U') (r' F R F') (BM)
x' (R U R' D) (R U' R' D') (VC)

Do x' R as l instead (normal RH, left thumb on U face).
setup: OCLL4 or OCLL3 / gives: OCLL4

(R' F) (R B') (R' F') (R B) (BB)

BB:This algorithm is ridiculously fast. Hold your thumb on the bottom of the cube and left middle finger holding the S layer on the upper face. It helps to use your wrist of your left hand to assist in some of the turns.

F' (r U R' U') (r' F R) (BM)
[y'] x' (R U' R' D) (R U R' D') x (VC)

Do x' R as l instead (normal RH, left thumb on U face).

BB:This is one of the most awkward OLLs with all correctly flipped edges. It's still pretty fast, though.
Note:VC does the D' by pushing with left ring finger.

E1 - 28
⇔ self or ⇐ E2

(M U M') U2 (M U M') (BB,BM) (edited)

BB:The middle slices should be done with the left ring finger for M' and the left thumb for M. The (M' U M) group may take some getting used to.
Edited because doing M U M' seems easier than doing M' U M. We do M(i1) U(I2) M'(R4) U2(i1,m1).

(r U R' U') R r' (U R U' R')

This is actually inverse of E2. Let's try this one, which reuse some finger tricks from other OLL, since I can get the move above to work for me (should try M with the thumb thing though someday).
Actually we do it more like (L F l' U') l L' (U R U' R'), where the left hand do most of the rotation for the first moves (the right hand barely moves). For the fingertricks, we do ({RH squeezes r} L {LH squeezes l while doing} F(i1) l' U'(i1)) l {RH squeezes back r} L' (U(I2) R U'(i1) R').
E1 / ⇐ E2² or M U (R U R' U') M' (U R U' R')

(R U R' U') M' (U R U' r') (BB,BM) (edited)

BB:There's nothing too fancy here. The finger tricks used are pretty common. I do the slice turn as M' now because I think it's a little faster that way.
Let's try to do the M' as such, and not like r R'. The fingertricks should be something like {TD,r-BD} (R U R' U') M'(r4) (U R U' r'). The difficulty is to stabilize the slice M when doing the last R. This can be done either with left ring finger, left thumb, or even left index (which, if left on TL edge is brought to TB edge with U).

⇔ self or ⇐ O1

[F (R U R' U') F'] [f (R U R' U') f'] (BB,BM)

BB:This algorithm is just the easy T-orientation followed by the easy P-orientation.The S can take a little getting used to.
Note:The F' f can be done as S.

[f (R U R' U') f'] U' [F (R U R' U') F'] (BB,BM)

BB:This is a clever combination of the two six move OLLs.
O3

[f (R U R' U') f'] U [F (R U R' U') F'] (BB,BM)

This is another combination of the two six move OLLs.
Note:Do the middle U with the right ring finger by sliding it on the U face.

[r' R U' r U²' r' U' R U' R' M'] (VC) (video)

Note:To run smoothly, RH must take the lead and hold the cube such that LH fingers are ready for the U' and M' moves.

[F (R U R' U) y' R'] U² (R' F R F') (BB,BM) (edited)

BB:This case has a couple of fast triggers in it.
Note: BM does the [... y' R'] U² as [... F' y'] U². Another variant is to do the y' U² as d' U.

[F (R U R' U) F'] U² (F' L F L') (Me)

I currently do: F (R U R' U) F' (RH, 2nd U with LH, F' with thumb) U² F' L (LH, F' with index w/o regrip) F (RH) L' Template:Bue

(L F' L' F)(L F' L' F) (U' F U' F').

Note: This is simply the inverse of O5
O5 / ⇐ L3² or O8 OCLL5 or O7 U2 OCLL4

M U (R U R' U') r R' (R' F R F') (BB,BM) (edited)

BB:This alg is the same as the "X" orientation (#20) except with a slight modification.
Note:Do first M with left index. BM does r R' as M', but I prefer this combination. BB does the first M as r' R, and R' R' F R F' as x (R'² U) (R U'), but probably with the same fingertricks.

⇔ self

M U (R U R' U') r'² R² (U R U' r') (BB,BM) (edited)

BB:Here, I use the slice as r' R because it flows a little nicer. This is the least common OLL case (1/216). The finger tricks here are pretty simple.
Note:BB does the first M as r' R. BM does the r'² R² as . Standard RH regrip before sexy move.

(R U R' U') (R' F R F') (BB,BM)

BB:This orientation makes up the second half of the Y-permutation. Both triggers are lightning fast, so this should easily be sub-1 second.
P1 or ⇐ P2

[F (R U R' U') F'] (BB,BM)

BB:This is the quickest and shortest OLL case. I use the left index for the U' and the right thumb for the F'.

P1 - 44
T2 or ⇐ A1

f (R U R' U') f' (BM,BB)

BB:This is very similar to the easy T orientation (#45) except with a double layer turn instead of just F. It is helpful to know the inverse to avoid a U2 before the alg.
T2 / ⇐ C2 or A4

[U2] f' (L' U' L U) f (BM,BB)

BB:This is just the mirror of OLL #44. I also recommend being able to perform this alg from a U2.

(R' U' F) (R' F' R U R) (VC)

This is inverse of C2. Standard grip, and regrip after F. F' with left index.

(R d) (L' d') (R' U) (l U l') (BB)

BB:There should be a nice balance between both hands in performing this algorithm.

(R U B' U') (R' U R B R') (BM) (edited)

Note: Sexy RH grip, left index on B face to prepare for the B', followed by U' by R thumb, and a RH regrip for the last trigger.

R d L' d' R' U R B R' (BM)

To try: Use B5' instead.

B6 or ⇐ W2 or A4

[y2] (R' U') F (U R U' R') F' R (BB)

BB:This is just the mirror of OLL #32, but I don't perform it as such. Instead, I do an algorithm that contains the inverse of the easy T orienation in it.

[y2] R' U' F U R U' R' F' R (BM)
L' d' R d L U' L' B' L (BM)
(L' U' B U) (L U' L' B' L) (custom)

Note: I just do as a mirror of P3, also for the grip.

To try: Use B6' instead.

(L' U' L U') (L' U L U) (L F' L' F) (BB,BM) (old fav)

BB:This is just the mirror of OLL #38. You could also do U2 and perform a right handed version of this algorithm.

[y2] (R' U' R U') (R' U R U) (R B' R' B) (BM, GAN 356i)

My new fav. I just can't get the (L' U' L U') correctly with the LH. Grip is right thumb on U face, all U move with LH except the first U. Then LH regrip for the B'.
P4 / ⇐ OCLL4 U E2

(R U R' U) (R U' R' U') (R' F R F') (BB,BM)

BB:There's nothing difficult about any of these three triggers.

"L" shapes

Recognition: If there is a double yellow (a yellow block) on the side, move it to F face. Otherwise there must be a yellow bar, move it to L face. Then:

  • If there is no yellow bar, it is either L1 or L2. The side with one yellow tells which face to turn.
  • If there is no yellow block, it is either L5 or L6. The yellow L tells to which direction turns the r move.
  • Otherwise it is L3 or L4. If the bar is on the left, it is L3 (with modified sledgehammer); if the bar is on the bar, it is the case similar to OCCL3/OCCL5

Look-ahead: Edges are swapped, corners don't move.
I1 / ⇐ I3 or f' (L' U' L U) (L' U' L U) f

L6 or L4 / ⇐ L4

(R' F R' F') R² U² y (R' F R F') (BB,BM)

BB:This algorithm is very similar to OLL #50 with an added cube rotation to make the second trigger easier to perform.
Note:Normal RH grip, LH index on F face to prepare for the F', RH does everything else without leaving the cube but for the Y rotation. Also, the Y move could be done as d' U', using the RH middle finger then LH index.

(r U' r'2 U) (r2 U r2' U') r (VC)

RH grip top/bottom face for the r moves. First U with left index (like in OH), second U with right hand.
L3 / ⇐ L4', ie. [x'] R U' R'² D R² U R'² D' R

[y²] (R B' R B R²') U² (F R' F' R) (BB)

BB:Use the right hand to do the first set of moves all in one motion. The second trigger should be very fast.

[x'] R' D R² U' R²' D' R² U R' (BM) (edited)

Note:Before the x', normal RH grip (but only squeezing middle layer), LH thumb on U face, only holding S slice. Do this similar to the OCCL3 or OCCL5, but doing instead of R.

(r' U' R) U' (R' U R) U' (R' U² r) (BB,BM) (edited)

BB:This is similar to OLL #54, but the first U' is done with the left index finger.
Note:normal LH grip, right thumb on U face. This is like OCLL1, but with fat R at the start and end. Alternatively, we can have a standard RH grip, and switch to sexy grip when doing (... R) U' (R' ...) to be ready for the next U.

[y²] l' U' L U' L' U L U' L' U² l (BM)

normal grip, first U' with right index
⇔ self or ⇐ L3 or I4

(r U R') U (R U' R') U (R U²' r' (BB,BM) (edited)

BB:The left hand only holds the cube while the right does everything else. This is sort of like a fat double Sune.
Note:... or Sexy grip, do everything with right hand but U'. Mirror version of L5 / OCLL1.
This is the best algo for me (measured on GAN 356i). I do: standard grip, first U, then U' and U²' with LH, all other upper face moves with RH. Except for first U with LH, all other U/U' moves fall nicely.

[y] (r U'2) (R' U' R U) (R' U' R U' r') (GAN 356i)

Note: This algo has a nice flow, but I can't get it faster than the one above. First U'2 with LH (two fingers), first U with RH (this requires sexy grip on start), then two last U' done with LH (using two differnt fingers).

[y] (r U r') (R U R' U') (R U R' U') (r U' r') (edited from VC I4-56)

Note:Variant of I4-56. Everything with RH, sexy grip, except the last U'..
This variant is not so good compared to the two above (measured on GAN 356i)

(r U R' U) (R U² r') (BB,BM) (edited)

BB:This case is just the inverse of one of the squares (OLL #6).
Note: This one is tricky. I do as follows. Normal LH grip, wide sexy RH grip to do the first U move, then R' U R with the R ring finger. Then by either LH or RH. For the movement with the R ring finger to go smooth, it is important that the LH holds the cube very tight and aligned.
S1 or ⇐ B3 or F2 or K3

(r' U' R U') (R' U² r) (BM) (edited)

BB:Like OLL #7, this is just the inverse of one of the squares (OLL #5).
Note:Very similar to anti-sune (AK variant), but with a wide start and end. Normal LH grip, anti-sune RH grip (right index under BDR corner). LH does all U' move and RH the move.

F (R' F) (R² U' R' U') (R U R' F²) (VC)

Note:After measurement, faster than formula above. Subset of T perm.

Setting UP OLL Cases

Here some guidelines to prepare a given OLL case:

  • Do the inverse OLL case (this case is given by the ⇔ or ⇐ symbol in the list above).
  • Combine two OLL setup cases, for instance a cross OLL like OCCL4 or OCCL5 and a E1/E2.
  • Learn the inverse OLL formulas, for instance OCCL3'.

Also, some inverse triggers:

  • Inverse right sledgehammer is left sledgehammer y (L F' L' F) y'

Partial Edge Control

  • Use R' F R F' (SL), instead of U R U' R' if no edge are correctly oriented.
  • For F2L case #35, use R U R' U2 R U' R' U R U' R' instead of usual F' U F U2' R U R' to keep edge orientation.
Rules of thumb
  • Edges on U face always keep their orientation when doing only U and R moves.
