List of pretty patterns

2018-08-20T13:35:04Z

Andydude:

A pretty pattern is an aesthetic state of a puzzle. Some cubers create and share pretty patterns for amusement.

==Examples of Simple Pretty Patterns==
===3x3x3 Cube===
{{Alg|M2 S2 E2}}
{{Alg|R2 L2 F2 B2 U2 D2}}

M2 E2 S2 - "Pons Asinorum", creates a checkerboard pattern on each face.

{{Alg|M2 S2 E2}}

M S M' S' - "6-Spot", moves all six center pieces around.

{{Alg|M S M' S}}

M2 S M2 S' - "4-Spot", moves four of the center pieces around.

{{Alg|M2 S M2 S'}}

(L2 F2 R2 B2)3 - creates a checkerboard on two opposite faces.

{{Alg|L2 F2 R2 B2 L2 F2 R2 B2 L2 F2 R2 B2}}

U R2 F B R B2 R U2 L B2 R U' D' R2 F R' L B2 U2 F2 - [[superflip]], flips all edges on the cube without affecting anything else.

{{Alg|U R2 F B R B2 R U2 L B2 R U' D' R2 F R' L B2 U2 F2}}

(M U M U M U M U X Y')3 - easier version of superflip

{{Alg|M U M U M U M U X Y' M U M U M U M U X Y' M U M U M U M U X Y'}}

U2 B2 U2 B2 L R F2 D2 F2 U2 L' R' - Creates the 'Speedsolving.com' logo on a physical cube. Doing the algorithm again re-solves the cube.

{{Alg|U2 B2 U2 B2 L R F2 D2 F2 U2 L' R'}}

===2x2x2 Cube===
Some patterns can be found easily just by doing a combination of 180 degree twists.

R2 F2 R2 U2 - creates a checkerboard pattern on four faces.

F2 R2 U2 F2 - creates a striped pattern on each face.

F2 R2 F2 - creates stripes on four of the faces. (This is also a [[PBL]] case.)

F2 R2 U' F' U R' U2 R U' F' - creates a 'cube in a cube' effect.

===4x4x4 Cube===
Create a checkerboard pattern on 4 faces.
{{Alg|3Rw2 Rw2' R2 3Fw2 2Fw2' F2 3Rw2 Rw2' R2 3Dw2 Dw2' D2|cube=4x4x4}}

===5x5x5 Cube===
Create a checkerboard pattern on 4 faces.
{{Alg|2Rw2 2Bw2 M2 2Fw2 2Lw2 E2 R2 B2 m2 F2 L2 e2|cube=5x5x5}}

Create a checkerboard pattern on 6 faces.
{{Alg|4Rw2 3Rw2' Rw2 R2' 4Fw2 3Fw2' 2Fw2 F2' 4Dw2 3Dw2' Dw2 D2'|cube=5x5x5}}

===Higher Order Cubes===
Create a checkerboard pattern on 4 faces.
{{Alg|5Rw2 4Rw2' 3Rw2 Rw2' R2 5Fw2 4Fw2' 3Fw2 2Fw2' F2 5Rw2 4Rw2' 3Rw2 Rw2' R2 5Dw2 4Dw2' 3Dw2 Dw2' D2|cube=6x6x6|comment=6x6x6}}
{{Alg|3Rw2 3Bw2 M2 3Fw2 3Lw2 E2 2Rw2 2Bw2 (5Rw2 2Rw2') 2Fw2 2Lw2 (5Dw2 2Dw2') R2 B2 m2 F2 L2 e2 z2|cube=7x7x7|comment=7x7x7}}
{{Alg|7Rw2 6Rw2' 5Rw2 4Rw2' 3Rw2 Rw2' R2 7Fw2 6Fw2' 5Fw2 4Fw2' 3Fw2 2Fw2' F2 7Rw2 6Rw2' 5Rw2 4Rw2' 3Rw2 Rw2' R2 7Dw2 6Dw2' 5Dw2 4Dw2' 3Dw2 Dw2' D2|cube=8x8x8|comment=8x8x8}}
{{Alg|4Rw2 4Bw2 M2 4Fw2 4Lw2 E2 3Rw2 3Bw2 (6Rw2 3Rw2') 3Fw2 3Lw2 (6Dw2 3Dw2') 2Rw2 2Bw2 (7Rw2 2Rw2') 2Fw2 2Lw2 (7Dw2 2Dw2') R2 B2 m2 F2 L2 e2|cube=9x9x9|comment=9x9x9}}

===Other Puzzles===
Pretty patterns are possible for every puzzle, but for some puzzles (such as [[Megaminx]]) the algorithms to create them would be so long and unwieldy that pattern creators do not even try to create them. In these cases it is necessary to just solve the puzzle into the required pattern, which is in fact one possible way to create any pattern on any puzzle.

}}
'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

}}
'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

}}
'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

}}
'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

}}
'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''PLL''' is the acronym for '''Permutation of the Last Layer'''. Permutation of the [[Last Layer]] is the last step of many speedsolving methods. In this step, the pieces on the top layer have already been oriented ([[OLL]]) so that the top face has all the same color, and they can now be moved into their solved positions. There are 21 PLLs (13 if you count mirrors and inverses as being the same) and each one is named after a letter. The following page gives a list of all of the PLLs, along with a picture and a list of common [[algorithm]]s for each one. The diagrams below are top views of where you want the pieces to go. For example, the [[PLL#T_Permutation|T Permutation]] (or 'T perm') swaps the UL and UR edges, as well as the UFR and UBR corners. If you like, try out all of the available algorithms for a case to see which one feels the fastest to you - the same algorithm may not be the fastest for everyone, and shorter algorithms are not always faster than longer ones. PLL is a subgroup of [[ZBLL]].

==Permutations of Edges Only==
This subgroup, [[EPLL]] is used as a [[substep]] for many speedsolving methods, for example in the [[VH method]] ([[COLL]]).

{{H-PLL}}
{{U-PLL(a)}}
{{U-PLL(b)}}
{{Z-PLL}}

==Permutations of Corners Only==
This is also known as [[CPLL]] (Corner Permute Last Layer). There is one more case in this group, the X-PLL but that is the same alg as [[H-PLL]] + U2, see [[EPLL]].

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''OLL''' (short for [[Orientation]] of the [[Last Layer]]) is a last-layer step for 3x3 that orients all last-layer corners and edges in one step. It is the first last-layer step in many speedsolving methods, including the [[Fridrich Method]]. OLL is usually followed by [[PLL]].

== Terminology ==
'''Dot OLL''' refers to OLL cases with no edge oriented correctly, so named because the center sticker forms a lone dot of the last-layer color. These cases are typically longer and harder to execute than others and are sometimes avoided. For example, cubers who have not learned full OLL can use [[partial edge control]] to avoid these cases altogether. Even some cubers who know full OLL avoid these cases for [[one-handed solving]].

=OLL Algorithms=
Parentheses in an algorithm signify the triggers of the algorithm. For example, [(R U R') (L' U L)] shows two triggers in the algorithm, even though it is the same as [R U R' L' U L].

The areas shaded in gray represent the oriented pieces on the top layer. You can tell if a piece is oriented by looking at the top color of the piece in relation to the top center of the cube. If the piece is oriented, the two colors will be the same.

The bars sticking off to the side of an unshaded piece represent where the [[sticker]] that needs to be on top is.

{{Algnote}}

==All edges flipped correctly==
This subgroup, '''OCLL''' (also '''OLL-C''') is used in methods which have oriented the [[LL]] edges earlier in the solve, such as [[ZZ]]. Solving the '''OCLL''' is also the second part of the [[2-look OLL]].

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

}}
'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.

The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.

[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.

 

== Approaches ==

=== Petrus F2L ===

Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.

=== Fridrich F2L ===

There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers.

The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.

'''OLL''' (short for [[Orientation]] of the [[Last Layer]]) is a last-layer step for 3x3 that orients all last-layer corners and edges in one step. It is the first last-layer step in many speedsolving methods, including the [[Fridrich Method]]. OLL is usually followed by [[PLL]].

== Terminology ==
'''Dot OLL''' refers to OLL cases with no edge oriented correctly, so named because the center sticker forms a lone dot of the last-layer color. These cases are typically longer and harder to execute than others and are sometimes avoided. For example, cubers who have not learned full OLL can use [[partial edge control]] to avoid these cases altogether. Even some cubers who know full OLL avoid these cases for [[one-handed solving]].

=OLL Algorithms=
Parentheses in an algorithm signify the triggers of the algorithm. For example, [(R U R') (L' U L)] shows two triggers in the algorithm, even though it is the same as [R U R' L' U L].

The areas shaded in gray represent the oriented pieces on the top layer. You can tell if a piece is oriented by looking at the top color of the piece in relation to the top center of the cube. If the piece is oriented, the two colors will be the same.

The bars sticking off to the side of an unshaded piece represent where the [[sticker]] that needs to be on top is.

{{Algnote}}

==All edges flipped correctly==
This subgroup, '''OCLL''' (also '''OLL-C''') is used in methods which have oriented the [[LL]] edges earlier in the solve, such as [[ZZ]]. Solving the '''OCLL''' is also the second part of the [[2-look OLL]].

'''OLL''' (short for [[Orientation]] of the [[Last Layer]]) is a last-layer step for 3x3 that orients all last-layer corners and edges in one step. It is the first last-layer step in many speedsolving methods, including the [[Fridrich Method]]. OLL is usually followed by [[PLL]].

== Terminology ==
'''Dot OLL''' refers to OLL cases with no edge oriented correctly, so named because the center sticker forms a lone dot of the last-layer color. These cases are typically longer and harder to execute than others and are sometimes avoided. For example, cubers who have not learned full OLL can use [[partial edge control]] to avoid these cases altogether. Even some cubers who know full OLL avoid these cases for [[one-handed solving]].

=OLL Algorithms=
Parentheses in an algorithm signify the triggers of the algorithm. For example, [(R U R') (L' U L)] shows two triggers in the algorithm, even though it is the same as [R U R' L' U L].

The areas shaded in gray represent the oriented pieces on the top layer. You can tell if a piece is oriented by looking at the top color of the piece in relation to the top center of the cube. If the piece is oriented, the two colors will be the same.

The bars sticking off to the side of an unshaded piece represent where the [[sticker]] that needs to be on top is.

{{Algnote}}

==All edges flipped correctly==
This subgroup, '''OCLL''' (also '''OLL-C''') is used in methods which have oriented the [[LL]] edges earlier in the solve, such as [[ZZ]]. Solving the '''OCLL''' is also the second part of the [[2-look OLL]].

'''OLL''' (short for [[Orientation]] of the [[Last Layer]]) is a last-layer step for 3x3 that orients all last-layer corners and edges in one step. It is the first last-layer step in many speedsolving methods, including the [[Fridrich Method]]. OLL is usually followed by [[PLL]].

== Terminology ==
'''Dot OLL''' refers to OLL cases with no edge oriented correctly, so named because the center sticker forms a lone dot of the last-layer color. These cases are typically longer and harder to execute than others and are sometimes avoided. For example, cubers who have not learned full OLL can use [[partial edge control]] to avoid these cases altogether. Even some cubers who know full OLL avoid these cases for [[one-handed solving]].

=OLL Algorithms=
Parentheses in an algorithm signify the triggers of the algorithm. For example, [(R U R') (L' U L)] shows two triggers in the algorithm, even though it is the same as [R U R' L' U L].

The areas shaded in gray represent the oriented pieces on the top layer. You can tell if a piece is oriented by looking at the top color of the piece in relation to the top center of the cube. If the piece is oriented, the two colors will be the same.

The bars sticking off to the side of an unshaded piece represent where the [[sticker]] that needs to be on top is.

==All edges flipped correctly==
This subgroup, '''OCLL''' (also '''OLL-C''') is used in methods which have oriented the [[LL]] edges earlier in the solve, such as [[ZZ]]. Solving the '''OCLL''' is also the second part of the [[2-look OLL]].

'''OLL''' (short for [[Orientation]] of the [[Last Layer]]) is a last-layer step for 3x3 that orients all last-layer corners and edges in one step. It is the first last-layer step in many speedsolving methods, including the [[Fridrich Method]]. OLL is usually followed by [[PLL]].

== Terminology ==
'''Dot OLL''' refers to OLL cases with no edge oriented correctly, so named because the center sticker forms a lone dot of the last-layer color. These cases are typically longer and harder to execute than others and are sometimes avoided. For example, cubers who have not learned full OLL can use [[partial edge control]] to avoid these cases altogether. Even some cubers who know full OLL avoid these cases for [[one-handed solving]].

=OLL Algorithms=
Parentheses in an algorithm signify the triggers of the algorithm. For example, [(R U R') (L' U L)] shows two triggers in the algorithm, even though it is the same as [R U R' L' U L].

The areas shaded in gray represent the oriented pieces on the top layer. You can tell if a piece is oriented by looking at the top color of the piece in relation to the top center of the cube. If the piece is oriented, the two colors will be the same.

The bars sticking off to the side of an unshaded piece represent where the [[sticker]] that needs to be on top is.

{{Algnote}}

==All edges flipped correctly==
This subgroup, '''OCLL''' (also '''OLL-C''') is used in methods which have oriented the [[LL]] edges earlier in the solve, such as [[ZZ]]. Solving the '''OCLL''' is also the second part of the [[2-look OLL]].

{{OCLL}}

==No edges flipped correctly==

I'm making images for this page ATM, there are already some but diffrent layouts and also diffrent from what I'm creating... I make images for all cases so the page gets a uniform look =) // [[User:Kenneth|Kenneth]] 09:52, 28 July 2010 (UTC)

: Have you seen this? [http://cube.crider.co.uk/visualcube.php?fmt=gif&view=plan&alg=M'UM'U2M'U'MUM'U2MU'M2&arw=U3U5-s7,U5U7-s8,U7U3-s8]
: The style may not be to your liking, but it may save you a lot of work ;-)
: [[User:Cride5|Cride5]] 21:50, 28 July 2010 (UTC)

::Yes, sure, I know about that but it does not save me any work, I got readymade images where I only have to fill in the stickers and that is faster than setting up the algs for each case. Naming, saving and uploading the images it the part that is most time consuming and that I have to do anyway =) // [[User:Kenneth|Kenneth]] 01:47, 29 July 2010 (UTC)

:BTW, I will remove the links to the OLL's from the page because OLL does not always preserve corner permutation; (x) L2 U2 R' U' R U2 L' U Rw' (J-PLL like) for example.

I think the algs for RF-flip U-PLL a and LF-flip U-PLL b are reversed or the pictures need to be reversed. The algs listed under RF-flip U-PLL a are the ones for LF-flip U-PLL b and visa versa.

:''This page is about the ELL that solves edges preserving corners, for the method that does not, see [[LLEF|LL edges first]]''
'''Edges of Last Layer''', or normally '''ELL''', is a [[method]] that solves the last layer [[edge]]s of the [[3x3x3]] in one algorithm as the last step in the solution, normally after performing [[CLL]] to solve the last layer [[corner]]s. There are 29 cases in ELL, of these are three pure flips, four are [[EPLL]] and six cases are 3-cycles (besides the two in EPLL), all useful also for other methods, like [[BLD]].

ELL is also used for a method of solving the last layer edges on larger cubes. Since there are 8 of each type of [[wing]], though, ELL for larger cubes requires more than one look due to the large number of cases, see [[KBCM Step 6|KBCM]] for a complete 3-look ELL for the [[4x4x4 cube]].

All ELL that are pure 3-cycles are used in the blindfold method [[TuRBo]].

== Intuitive==
If you like to find algs for ELL in the MU-group, then knowing these short "proto algs" will help a lot:

* O = M' U M ... Orient
* O' = M' U' M ... Orient inverse
* P = M' U2 M ... Permute

If you combine these and also insert U-turns you can find optimal or near optimal algs for most ELLs

Example, 4-flip: '''P U2 O U2 P U'''' ... P U2 sets up for O that flips four edges (O' works the same in this case, choose the fastets), U2 P is restoration of the setup and last U is AUF.

==2-look ELL==
Use any ELL that orients what you currently got (3 cases) from the listings below and finnish it using [[EPLL]] (4 cases). Most [[OLL]]s that preserves corner orientation will probably also do for the first look but don't count on it, some may change corner permutation while orienting the edges.

Another way to solve ELL in 2 looks is to use [[L5E]], but that is desigend for solving one more edge than this is so there will be nearly the same number of algs as full ELL (5+16).

=ELL Algorithms=
{{Algnote}}

The naming convention here is; wich edges are fliped if they where [[permute]]d and which [[EPLL]] would it be if all was correctly [[orient]]ed.
