(Placement Arêtes Sommets Centres par Algorithmes Limités)

BASED ON ZZ

IMPORTANT

for all the resolution of the cube

the cube is positioned with the centers as below

GENERAL

PRINCIPLE ZZ

The goal is to take a resolution

with the least regrip of the cube

few movements and almost only in L U R

PRINCIPLE OF ORIENTATION OF THE EDGES

starting from a mixed cube

you have to reorient all the edges

so that the colors PERFECTLY respect the following diagrams

FACE U and D FACE F and B FACE R and L

ALL THE TIME NEVER ALL THE TIME

it sounds complex but it's only an impression!

it's confusing, but very simple and fast

STEP 1 - Orient the edges of the first side D

can be done, but not necessarily, like the CFOP Fridrich method

easier with the white face D positioned to the left of the cube

we place edges that are white, yellow green or blue

paying attention to the stress of the faces F and B

this is done intuitively and very quickly (less than 5 movements)

much simpler than a classic white cross (CFOP)

STEP 2 - Orient the last edges

It remains in all cases 0, 2, 4, 6 or 8 misdirected edges

this is done in

1 step if 2 to 4 KO edges

2 steps if 6 or 8 KO edges

position the cube according to the general diagram

MOVE with R L U D or inverse movements and F2 B2

all KO edges on the front face

when the 4 KO edges are placed in F

ORIENTATE with a simple movement F or F'

when there are only 2 KO edges the principle is slightly different

MOVE with R L U D or inverse movements and F2 B2

1 KO edge (A) on the front face and the other one (B) on the high side

and positioned on the same slice, according to the diagram

ORIENTATE (A) by F'- BRING (B) by U - ORIENTATE (B) by F = either F' U F

STEP 3 - Make 1 line of OK edges in front of D

with only R L U D or inverses and F2 B2

we come to

( STEP 3 can be done at the same time as STEP 1 or even before )

STEP 4 - Place 3 edges and their summits (ZZF2L)

this is done like F2L from CFOP Fridrich

but in a simpler way, because following the orientation of all the edges,

Frequently, there are F2Ls that form on their own!

we only use R U L !

there is no regrip of the cube !

in principle we build on the R or L side

1 F2L to which is added 1 edge to make 1 block 2X2X1

we do the same thing on the other side

and we end with 1 classic F2L

everything is instinctive !

STEP 5 - Place the latest F2L

like all the edges have been oriented

the placement of the last F2L gives directly the yellow cross oriented !

but it is possible to do even better ...

using some very simple algorithms

we can have the yellow cross oriented and placed +/- !

to do this, you must identify the color of the edge :

and the position of the opposite-colored edge:

is

BLUE <> GREEN or RED <> ORANGE

There are 6 different + symmetrical cases

we thus arrive at 2 possible situations

CROSS OR BAR

according to each case the end of the cube is different but very simple and fast !

STEP 6 - END OF THE CUBE

guide all the summits

5 easy and fast cases.

even if there are many others, but not shorter

it's important to use these algorithms,

because they all preserve the placement of the edges

sometimes there is no well-directed summit, then do 1 ou 2

IF the CROSS is OK

place all the summits to finish the cube

General cases : Particular case :

( If no Summit OK, do 1 of the 2 algorithms ) (4 summits that move in X)

If no summit is well placed, do 2 times the general case

IF the BAR is OK

place all summits and 2 KO edges to finish the cube

5 cases are 5 PLL of CFOP Fridrich

CUBE IS RESOLVED!

this method is based on ZZ

this technique always guarantees to have a yellow cross oriented at the end of F2L

the trick is to take this opportunity to solve the last face of the cube with

very few algorithms

quick sequences

easy identification

you only need to know 25 algorithms (6 of which are symmetric)

it's a lot, a lot less than

ZZ full

CFOP Fridrich

Roux Method

this method remains very powerful and simple

more than the techniques of beginners

more than intermediate solutions

more than CFOP Fridrich OLL 2 steps + 21 PLL
