How to solve a Rubik's Cube BLD + Progression

[Zane_C]

Hello everyone,

I've spent the last few weeks working on this tutorial.
I didn't intend on this to be a Christmas present, it's just a coincidence I've finished on Christmas.

I've attempted to make this tutorial as thorough and understandable as possible.
Hopefully this will motivate more people to learn how to solve the Rubik's Cube blindfolded.

Sorry for the boring voice.

Zane.

FD = Lw' (J-perm) Lw
FL = L' (T-perm) L
LU = L' Dw L' (T-perm) L Dw' L
LF = Dw' L (T-perm) L' Dw
LD = D Lw' (J-perm) Lw D'

BL = L (T-perm) L'
BD = Lw (L-perm) Lw'
BR = Dw2 L' (T-perm) L Dw2
RB = Dw L (T-perm) L' Dw'
RD = D' Lw' (J-perm) Lw D
RF = Dw' L' (T-perm) L Dw
DF = D' L2 (T-perm) L2 D
DL = L2 (T-perm) L2
DB = D L2 (T-perm) L2 D'
DR = D2 L2 (T-perm) L2 D2

Solution for corner targets:
UBR = L-perm or R D' (Y-perm) D R'
UFR = F (Y-perm) F'
UFL = F R' (Y-perm) R F'
FLU = F' D (Y-perm) D' F
FRU = R2 D' (Y-perm) D R2
FRD = R F (Y-perm) F' R'
FLD = D (Y-perm) D'
LFU = F2 (Y-perm) F2

BUR = R' F (Y-perm) F' R
BDL = D' R (Y-perm) R' D
BDR = D' (Y-perm) D
RUF = R' (Y-perm) R
RUB = R2 (Y-perm) R2
RDB = R (Y-perm) R2

Example solve #1 (with parity and flipped edge):

Spoiler

Scramble cube in the orientation you wish to solve it in.
Scramble: R L U2 D2 L2 B2 R' B2 U2 F2 L2 B D' B' D' L' U' L2 B' D2 R

Corners:
UBR = R D' (Y-perm) D R'
DBL = D F' (Y-perm) F D'
FLU = F' D (Y-perm) D' F
FRU = R2 D' (Y-perm) D R2
DFL = F' (Y-perm) F
DFR = F' R' (Y-perm) R F
RBD = R (Y-perm) R'

Fix parity: y' (R-perm) y

Edges:
DL = L2 (T-perm) L2
DF = D' L2 (T-perm) L2 D
UB = L-perm
RD =D' Lw' (J-perm) Lw D
BR = Dw2 L' (T-perm) L Dw2
DB = Lw2 (J-perm) Lw2 or D L2 (T-perm) L2 D'
LB = Dw L' (T-perm) L Dw'
UF = J-perm
FL = L' (T-perm) L
FR =Dw2 L (T-perm) L' Dw2
UB = L-perm

Flip UL:
shoot to UL: T-perm
shoot to LU: L' Dw L' (T-perm) L Dw' L

Example solve #2 (with parity and twisted corner):

Spoiler

Example solve #2:

Scramble cube in the orientation you wish to solve it in.
Scramble: U' L2 U' L U R' F L' U2 B U R2 U R2 U B2 U2 B2 D' F2 D

Corners:
UFR = F (Y-perm) F'
BDR = D' (Y-perm) D
LDB = D2 (Y-perm) D2
FDR = R F (Y-perm) F' R'

Since the buffer piece is now permuted (in place), you need to break into a new cycle. I have arbitrarily chosen to shoot to UBR...

UBR = R D' (Y-perm) D R'
DFL= F' (Y-perm) F
UBR = R D' (Y-perm) D R'

Twist FLU corner: first shoot to FLU, since that's the sticker that belongs facing up, then shoot to UFL...

FLU = F' D (Y-perm) D' F
UFL = F R' (y-perm) R F'

Since there was an odd number of targets, parity exists.
Fix parity: y' (R-perm) y

Edges:
FR = Dw2 L (T-perm) L' Dw2
BL = L (T-perm) L'

Break into new cycle with UL...

UL = T-perm
FL = L' (T-perm) L
LU = L' Dw L' (T-perm) L Dw' L

Break into new cycle with UB...

UB = L-perm
FD = Lw' (J-perm) Lw
UF = J-perm
BR = Dw2 L' (T-perm) L Dw2
BD = Lw (L-perm) Lw'
DR = D2 L2 (T-perm) L2 D2
LD = D Lw' (J-perm) Lw D'
BU = Lw (J-perm) Lw'

Image suggestions for edge targets:

Spoiler

UF = UFO
UL = Ultra-quick (the Flash)
UB = sUBmarine
FU = Fugitive
FR = Fridge/fruit
FD = Food
FL = Flower/flour/flood
LU = Lute
LF = Leaf
LD = Lead
LB = Lobster
BU = Bull
BL = Blood
BD = Bed
BR = Bear
RB = Robber
RD = Rubber Duckie/road
RF = Roof/rifle
DF = Dolphin
DL = Doll
DB = Disco Ball
DR = Dragon

Memo can be easier to recall if you interact 2 images per location.
For example: BR+LB could be imagined as a bear eating a lobster.

Formula to reassure yourself that all pieces have been cycled: t = u + c
If t = u + c, you have cycled all the pieces.

Where:
t = No. of targets (excluding targets associated with flipping edges or twisting corners)
u = No. of unsolved pieces (excluding buffer and flipped/twisted pieces)
c = No. of cycle breaks (ie. how many times you break into a new cycle)

Don't feel compelled to use this formula, it's just something you can use. Another way to make sure you've cycled all the pieces, is to simply study your memorisation, and check that no unsolved pieces are left out.

This video is for people who can already solve a cube blindfolded (BLD). This is mainly directed at users of the Classic Pochmann method.

Algorithms used:
T-perm flip: x' R2 U' R' U x R' F' U' F R U R' U'
Adj-edge flip: R' U2 R2 U R' U' R' U2 r U R U' r'
Mono flip: [R' D R D' R' D R] U' [R' D' R D R' D' R] U
Y-perm: R U' R' U' R U R' F' R U R' U' R' F R

Thanks Zane!!!!

 

[Andreaillest]

Thank you so much Zane! This is extremely informative, helpful, and a great reference. :tu

 

[Ickenicke]

Thank you!

 

[Innocence]

It's funny...I remember following your progression as a BLD cuber, Zane. I remember sometime, back on speedsolving, you posting about your first success.

Thank you so much for giving back to the community, and slow people like me.

 

[5BLD]

Very good tutorial, the progression video gave me some good key points!

 

[Brest]

Oh wow, this is fantastic! Great job Zane, love your work. :tu

 

[MostEd]

im inspired, im doing solves of edges using t perm, and going to expand the range
then going to practice corners

 

[Reinier Schippers]

Going through this right now, I learned a lot from Badmephisto.. but didn't finished it off with the corners, hopefully yours work!

I still find it hard for the right orientation. Edges are easy but the corners are quite hard for me. the place where the corners had to go is not that hard. But the right set up moves for the right orientation for the corners is the hardest for me. Very clear tutorial !

 

[PandaCuber]

YES! This is what i needed! Thank you so much.

 

[emolover]

And to think I just got my first success yesterday. Nice tutorial though.

 

[Owen]

Good, but too many algorithms :/

 

[Schmidt]

Edges are easy but the corners are quite hard for me.

You could test your corner skills with a 2x2x2

 

[Michael1026]

Wow, very nice. Thanks for this.

 

[Penguino138]

Zane, PLEASE make an M2 tutorial!

 

[Zane_C]

Thanks for the comments everyone.

Good, but too many algorithms :/

If you don't mind the setup moves being longer, you can use T-perm to solve all the edges.
Also, the progression video shows you how to solve parity without R-perm. That's just T-perm and Y-perm.

If you wanted to be really lazy, you could switch the corner buffer to UBR and solve everything with T-perm.

Zane, PLEASE make an M2 tutorial!

I was planning on making one. If I do make an M2 tutorial, it'll be made under the assumption that Classic Pochmann is already known. That way, I don't have to repeat basic concepts/terminology that is already covered in this tutorial.

 

[Mal]

If you made a M2 tutorial It would be much appreciated!

 

[Akash Rupela]

Well Zane, I m not sure if you remember helping me with BLD earlier this month, but really a big thankyou to you. You are a great help, and the best motivation for BLD anyone can have. I dint even see the video yet (seeing it now), just saw this thread, read the comments, felt motivated, did BLD 3-4 hours last night , and got a PB of 3.14.xx (earlier one wasnt even sub5) with old pochmann. I m sure watching the video will make me much better You are awesome!

 

[YrMyKnight]

I'm new to BLD cubing and so I'M GONNA LEARN MY ASS OFF D

 

[chris410]

Looking forward to this! Pen/paper will be in hand tomorrow morning! Thanks in advance.
