Orientation of Last Layer (OLL)
First of the two last-layer steps, OLL corrects the orientarion of all last layer pieces in one step so that all U-stickers have the U-color. Permutation is not preserved.
The images represent the last layer, with a gray square or a black side bar indicating U-stickers. Each algorithm applies with this layer as U; click on any algorithm to view it on an applet. Most of these algorithms have been taken from or are based on those by other cubers. Try other lists to find your favorite.
The placement of the correctly oriented last-layer pieces are easy to see, so recognition depends on being able to quickly tell between different patterns with the same top view. It helps to practice recognizing each pattern from the top and two adjacent sides.
OLL has the lowest speed increase per case learned of all steps of the Fridrich method; a 25-second cuber may only gain 2 seconds by replacing an efficient two-step OLL by full OLL (47 additional algorithms). Although any serious CFOP user should learn eventually learn full OLL, it should be noted that working on better F2L look-ahead is a more efficient way to get faster.
The algorithms are organized by similarity to aid memorization. See the printable page for the original order.
Before you even begin considering full Fridrich, you should know 2-look OLL. These account for 10 out of the 57 cases.
- OLL 45: 1/54
- 6-move T
- OLL 1: 1/108
- OLL 27: 1/54
- (Right) Sune
- OLL 26: 1/54
- OLL 21: 1/108
- OLL 22 ("The Wheel"): 1/54
- The fingertrick here is called the Air Jeff, after my friend Jeff Black. Hold the R layer with all five fingers, four on top and the thumb on bottom. This grip never changes. Do R, double trigger U2' with the left index finger, R2', left trigger U', etc. The key is to alternate the direction of R2.
- OLL 23 ("Headlights"): 1/54
- OLL 25 ("The Finger"...ask Bob Burton): 1/54
The 6-Move T Group
Many OLL algorithms can be grouped by similarity. You already know 45 and 44 from 2-step OLL; they are replicated here for reference. This group contains the various algorithms made by combining their mirrors and inverses.
- OLL 45 (6-move T): 1/54
- The easiest OLL
- OLL 2: 1/54
- OLL 48: 1/54
- Double 6-move T (F'-F cancelled)
- OLL 47: 1/54
- OLL 3: 1/54
- OLL 4: 1/54
You just learned 7 new algorithms, bringing the total to 17.
The Sune Group
These algorithms are all similar to Sune (OLL 26/27 from 2-Step OLL), which are replicated at the top. It shouldn't be too hard to learn these rotated by U2.
- OLL 27: 1/54
- Sune. Mirror of 26.
- OLL 26: 1/54
- OLL 9: 1/54
- OLL 10: 1/54
- OLL 11: 1/54
- OLL 12: 1/54
- OLL 41: 1/54
That's 12 more cases! We're already at 29 OLL cases.
Consider how the Sune (RUR'URU2'R') affects the FR F2L pair: RUR' removes the pair to the last layer and URU2'R' reinserts it differently, so that overall only the last layer is affected. A similar analysis applies to OLL 1 (RU2'R2'FRF'-U2'R'FRF'): RU2'R' removes the FR pair; R'FRF'U2' plays only with last layer pieces; and R'FRF' reinserts the pair. Combining different ways to remove, play, and reinsert an F2L pair gives rise to a number of good OLL algorithms, and this analysis makes them easier to memorize.
- OLL 37: 1/54
- OLL 36: 1/54
- OLL 57: 1/108
- OLL 17: 1/54
- Remove-reinsert as in 33, play in between.
- OLL 1: 1/54
- OLL 35: 1/54
- Remove-play as in 1, reinsert differently.
- OLL 18: 1/54
- OLL 29: 1/54
- Ending more like Rw2'FRwU'Rw
- for OH
- The Connie OLL. A lesson in non-standard fingertricks. Start with right thumb on F so that RFR' is done without regrip, then U with left index push usually used in OH.
- from Vincent Sheu
- Play with FR pair. Could be fast with right index push for F'.
- OLL 30: 1/54
- for OH
- The Connie OLL. Starting with the RH as if after R2', R2UR'B'RU'-R2'URBR with RH ring finger B' and 180 regrip at the dash. Also several ways to do this without regrip (all using an index push), but not as nice as in 29.
- From Algobase
That's 11 more algorithms, bringing the total to 38 out of 57. This is where things start to get tough.
Although these algorithms don't fit exactly into the "move around one corner-edge pair" paradigm, many can still be analyzed in a similar way by splitting into recognizable fragments. Some of the last few are especially tricky.
- OLL 52: 1/54
- OLL 14: 1/54
- Inverse of the non-Sune alg for 10.
- OLL 15: 1/54
- OLL 32: 1/54
- Inverse of 39
- OLL 19: 1/54
- OLL 20: 1/216
- OLL 34: 1/54
- OLL 56: 1/108
- OLL 49: 1/54
- Close to RwU'-Lw2'ULw2ULw2'U'Lw.
- OLL 50: 1/54
- OLL 55: 1/108
