'''VHF2L''' (short for ''[[Vandenbergh-Harris]] [[F2L]]'') is a step of the [[Vandenbergh-Harris]] method that basically does the same thing as [[ZBF2L]] using much fewer algorithms--the last slot is filled in while orienting the edges of the last layer. The reason why there are much fewer algorithms is because all of the cases have a F2L pair already or just one move away from making one. If the cube doesn't apply to that, you have to create a F2L pair or make it one move away.

'''Benny''' is the name for a corner permutation algorithm by [[Lars Petrus]]. It looks like a [[Sune]], but it is a bit different. It cycles four corners clockwise, swaps UL and UB, and orients the last layer. Benny is also a [[ZBLL]] algorithm.

EOLine

ThePCKid: /* EO Detection */

The first and most important step of the [[ZZ Method]]. It involves orienting all 12 edges, while simultaneously placing the ''line edges'' (DF and DB). After the [[EO]] part, the cube is reduced to <R, U, L, D, F2, B2>. After placing DB and DF, the cube is reduced to <R, U, L>, meaning it can be solved completely by turning only the R, U and L layers.

== Solving Procedure ==
=== EO Detection ===
Looking at the edges on the U face, D face, F face of the E-slice, and B face of the E-slice:
* If the sticker has L/R color it's a bad edge.
* If the sticker has F/B color, look at the sticker on the other side of the edge.
: * If the side sticker has U/D color, it's a bad edge.

=== Orienting 2 Bad Edges ===
Place one bad edge on F/B using <R, U, L, D, F2, B2> and then do a F/B quarter turn. Repeat with Orienting 4+ bad edges approach.

=== Orienting 4 + Bad Edges ===
Place four bad edges on F/B using <R, U, L, D, F2, B2> and then do a F/B quarter turn. Repeat until there are no more bad edges.

=== Orienting 6 Bad Edges ===
Often, 6 bad edges can be oriented more efficiently by placing 3 bad edges into F/B using <R, U, L, D, F2, B2>, performing an F/B quarter turn, and then using the 4 + approach to correctly orient the remaining 4 bad edges.

=== Solving the Line ===
Place DF and DB in their solved positions using <R, U, L, D, F2, B2>.

== EO+Line ==
In order to improve ease of learning and simplify the planning step, beginners may treat EOLine as two steps - EO+Line. Using this approach only EO is planned during inspection. The solver looks-ahead for the line edges during EO execution to plan for placement of the line. Although sometimes a useful fallback for difficult EOLine cases, EO+Line causes the solver to focus on the line edges during the inital steps, rather than looking ahead for the first 1x2x2 block. This significantly reduces the likelyhood of a smooth transition from EOLine to F2L.

== EOCross ==
Sometimes, DL and DR are also solved before [[ZZF2L]] (3-gen [[F2L]]). This is known as EOCross. This practice is common among solvers making the transition from CFOP as it allows F2L to be solved in much the same way as before. Although useful for making the transition, using EOCross is generally regarded as slower than EOLine because it is extremely difficult to plan and execute as a single step, and also results in a significantly less efficient F2L.

Sune

{{Method Infobox
|name=Sune

|steps=1

}}
The term '''Sune'''; (soon-ay), was coined by [[Lars Petrus]] for his method, and is the most widely recognized name for the sequence of moves and the case. Sune is a male name in Sweden and is a iron age form for 'the son', in mordern Swedish that is 'sonen'.

The mirror/inverse alg/case is named '''Antisune''' (or Anti Sune).
Using double layers for the first and second moves it is called a '''Fat Sune''' (r U R' U R U2 r').

===Algorithm===
Sune is a [[2-gen]] [[algorithm]] that affects the [[LL|last layer]] of a [[3x3x3|Rubik's Cube]], and can be applied to other [[puzzle]]s.

The Sune is most canonically written as R U R' U R U2 R'

There are many algs related to and/or derived from the Sune, such as its inverse, the Anti-Sune.

The Sune can be written as a pure [[commutator]], but is most commonly recognized as a [[conjugate]]d commutator or a sequence of two commutators.

'''Usage of the algorithm:''' Most often a [[OLL]] in the [[Fridrich Method]] or a [[CO]] for any cube, but also a [[COLL]] in the [[VH|Vandenbergh-Harris Method]], a [[CLL]], a [[ZBLL]] and besides that you can use it to to do 3-cycle edge permutation if corners are ignored and more...

===Case===
All cases of the [[last layer]] that has three corners twisted is a 'Sune case'.

EOLine

2011-01-22T23:23:08Z

ThePCKid:

The first and most important step of the [[ZZ Method]]. It involves orienting all 12 edges such that they may be solved using only <R, U, L, D, F2, B2> moves, while simultaneously placing the ''line edges'' (DF and DB). After the [[EO]] part, the cube is reduced to <R, U, L, D, F2, B2>. After placing DB and DF, the cube is reduced to <R, U, L>. Sometimes, DL and DR are also solved before [[ZZF2L]] (3-gen [[F2L]]). This is known as EOCross. Most of the time, EOLine is treated as two steps -- EO+Line.

== Step 1: EO ==
Look at the U layer, D layer, F face of the E-slice, and B face of the E-slice.
* L/R sticker -- bad edge
* F/B sticker
** U/D sticker on other side of edge -- bad edge

=== >=4 Bad Edges ===
Place four bad edges on F/B using <R, U, L, D, F2, B2> and then do a F/B quarter turn. Repeat until there are no more bad edges.

=== 2 Bad Edges ===
Place one bad edge on F/B using <R, U, L, D, F2, B2> and then do a F/B quarter turn. Repeat with the >=4 bad edges rule.

== Step two: Line ==
Place DF and DB (DL and DR for EOCross) in their solved positions using <R, U, L, D, F2, B2>.

Roux method

2011-01-12T23:51:49Z

ThePCKid:

{{Method Infobox

|proposers=[[Gilles Roux]]

|steps=4
|algs=11-71

}}

The '''Roux Method''' was invented by [[Gilles Roux]]. Unlike [[Fridrich]] and [[Petrus]], the inventor of this [[method]] has done a sub-15 second average (of 5) with it in competition. This method is influenced by the block building of the Petrus method and the layer on the left and edges last aspects of the [[Waterman method]].

==The Steps==

1. Build a 1x2x3 block anywhere on the cube.

2. Build a second 1x2x3 block opposite of the first 1x2x3 block, without disrupting the first 1x2x3 block. After this step, there should be two 1x2x3 blocks: one on the lower left side, and one lower right side, leaving the U slice and M slice free to move.

3. Simultaneously [[orient]] and [[permute]] the remaining 4 corners on the top layer (U-slice). You can use [[CMLL]],[[COLL]], or Corner OLL's (along with T and Y permutation) to do this.

4. [[Orient]] the 6 remaining edges (UF, UB, UF, UR, DF, DB need to be oriented correctly).

5. Solve the left and right layer edges. After this step, both the left and right side layers should be complete.

6. Solve the centers and edges in the M slice, ''see [[Last Six Edges]]''.

''See also: [[L5E]]''

==Pros==

Like the Petrus method, the Roux method uses fewer moves than the popular Fridrich method. It is also more intuitive and requires fewer algorithms. After the first block is built the rest of the cube can be solved with R, r, M and U moves thus eliminating rotations.

==Cons==

Block building can be difficult for a beginner to get used to. The reliance on r and M moves may also be difficult for some people, so much so that cubers who have trouble with M turns should probably not use this as their main method (or better, practice practice practice the M moves). Slice turns can also be slower than using a [[quarter-turn metric]].

First Two Layers

'''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. Normally it is as above but it may also refer to the part of the [[Fridrich method]] that solves the [[pair]]s without counting the [[cross]] part.

[[2-gen]] F2L, most pairs (30:42) 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, and then inserted into the correct slot. 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 [[Ren Schoof]] in 1981.

'''VHF2L''' (short for ''[[Vandenbergh-Harris]] [[F2L]]'') is a step of the [[Vandenbergh-Harris]] method that basically does the same thing as [[ZBF2L]] using much fewer algorithms--the last slot is filled in while orienting the edges of the last layer. The reason why there are much fewer algorithms is because all of the cases have a F2L pair already or just one move away from making one. If the cube doesn't apply to that, you have to create a F2L pair or make it one move away.

'''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. Normally it is as above but it may also refer to the part of the [[Fridrich method]] that solves the [[pair]]s without counting the [[cross]] part.

[[2-gen]] F2L, most pairs (30:42) 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, and then inserted into the correct slot. 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 [[Ren 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. Normally it is as above but it may also refer to the part of the [[Fridrich method]] that solves the [[pair]]s without counting the [[cross]] part.

[[2-gen]] F2L, most pairs (30:42) 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, and then inserted into the correct slot. 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 [[Ren Schoof]] in 1981.

VH is a variant of the [[Fridrich]] method, which orients the [[last-layer]] edges during insertion of the final [[F2L]] block. It has exactly the same effect as the [[ZBF2L]] stage of the [[ZB method]], but uses much fewer algorithms - 32 as opposed to ZBF2L's 125 (excluding mirror's and inverses). It achieves this by restricting the LL orientation step to the moment before insertion of the final 1x1x2 block (in a similar manner to [[Winter Variation]]). With full ZBF2L, LL orientation is carried out from ''any'' F2L last slot case.

'''PLL''' is the Permutation of the [[Last Layer]], 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. Make sure to 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]].

{{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]].

 {{OLL}}

=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. Normally it is as above but it may also refer to the part of the [[Fridrich method]] that solves the [[pair]]s without counting the [[cross]] part.

[[2-gen]] F2L, most pairs (30:42) 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, and then inserted into the correct slot. 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 [[Ren Schoof]] in 1981.
