- Hey everyone,

So yeah the work on the webpage is not proceding very well due to my

jobs :-(

I really don't want to be the guy that says I'll write up some info

but then never does. So, here is an example solve of 4x4x4 BLD -

literally every single thing that goes through my head when I do a solve.

Below is the scramble and the description of everything about the

solve. Before you scramble please hold the cube in the same

orienation you consider to be the "solved" orientation. This will

make it much easier to follow along with what I am doing.

Scramble:

F B R2 b r D' B' d2 l' D2 b L' U2 L2 f d' F' b l2 U' d2 L' F' D2 B2 L

f2 F2 d' f' b d B2 b r2 D2 f U2 d l

I actually memorized and solved this scramble before typing up this

example to make sure I would write up exactly what I do, even during a

real solve. The overall time was 8:41.85 minutes, which is pretty

much right at my average lately, which has been in the 8:40's. The

memorization step took 4:33 minutes and the solving then took 3:58

minutes.

After the scramble I always rotate the cube around to find the

position with the most centers already solved. After scrambling the

cube I did the rotation z' x'. If you don't like xyz notation I first

rotated the whole cube counterclockwise as if I was doing the move F'

and I then rotated the whole cube as if I was doing the move R'

After the cube rotation I now have the following cycles on the cube:

centers:

lbU -> ufR -> ulF -> brD -> drB -> lfD -> rbU -> buL -> flU -> dbL ->

urF -> dfR -> rfU -> drF -> dbR -> rfD -> dlF -> lbU

edges:

1) (lBU -> fUR -> fUL -> lDB -> uFR -> fDR -> rDB -> bUR -> lUF -> dBL

-> uFL -> uBR -> bDL -> dFR -> rBU -> lDF -> uBL -> bDR -> lBU)

2) (rUF <-> dFL)

3) (bUL -> fDL -> dBR -> rDF -> bUL)

I always memorize and solve in this order for the 4x4x4:

1) memorize center permutation

2) memorize edge permutation

3) memorize corner permutaiton

4) memorize corner orientation

5) solve corner orientation

6) solve corner permutation

7) solve center permutation

8) solve edge permutation

During the memorization of this solve I debated memorizing and solving

with center blocks on the F and R faces, but decided against it

because I had already memorized one of the pieces I would have made a

block out of into an image, and didn't want to rewrite the first

journey location any.

*****************

MEMORIZATION STEP

*****************

center cycle: lbU -> ufR -> ulF -> brD -> drB -> lfD -> rbU -> buL ->

flU -> dbL -> urF -> dfR -> rfU -> drF -> dbR -> rfD -> dlF -> lbU

center cycle in letters: A -> I -> E -> V -> O -> W -> B -> Q -> C ->

S -> F -> K -> D -> H -> L -> X -> G -> A

The journey I was using was halfway through one of my 28 location

journeys. This particular journey is a walk from my dormitory my

junior year of college through to my class on the other side of campus.

At each location I need to put at least three images, sometimes more

which does happen on this solve during the edge memorization.

Let me walk through each location one at a time:

Location 1:

-----------

This location is outside the dining hall with a bunch of tables and

chairs.

At this location I have the letters AIEVO. I take the very first

letter and give it a single letter image (famous person). This is so

I know which piece is the first piece of every one of my three cycles.

The letter is "A" so the image is "Dan Aykroyd".

Ok, so now I have to take the letters in pairs after the first image

is made. The next two are IE which is the Internet Explorer logo,

only about 6 feet tall. The next two letters are VO which is a 2 foot

tall Volcano that is spewing and erupting a huge column of ash.

I put these images in a left-to-right order. So on the left Dan

Aykroyd is rolling a giant 6 foot tall model of the Internet Explorer

logo onto the top of the two foot tall volcano to clog it up and make

it stop erupting ash everywhere.

That's it. I don't really view the motion, it is just implied. I see

the tables and chairs and the dining hall very clearly in the

background, and in the foreground I see Dan Aykroyd (motionless) in

the act of rolling the Internet Explorer logo onto the volcano. I

picture the logo about 3/4 the way up the volcano, so that the volcano

is still to the right of the Internet Explorer logo, which is to the

right of Dan Aykroyd.

Location 2:

-----------

This location is beside a wall about 20 feet away from the dining hall

on the way to a set of stairs.

At this location I have the letters WBQCSF. I now take letters in

pairs always to make double images. The letters WB form the image of

a giant 6 foot tall spider web between two large tree limbs. The

letters QC form the image of a two foot tall Quaich. The letters SF

form an image of a 4 foot tall model of the San Francisco Golden Gate

bridge.

At this location I can very clearly see the wall, as well as the hand

railing leading to the stairwell that is the next location (all in the

background). In the foreground I very clearly see (in left to right

order) a giant web where a Quaich is falling into it having rolled off

the end of the miniature San Francisco Golden Gate bridge.

Location 3:

-----------

This location is at the bottom of the stair case pictured at the last

location. I view it from the top of the staircase, looking at the

space just after the last step at the bottom. There are maybe 6 steps

to this staircase.

The letters at this location are KDHLXG. KD forms the image of Billy

the Kid the famous gunslinger. HL form the image of Satan as

described by Dante in Dante's Inferno. The only difference is my

image of him is about 5 feet tall instead of the massive proportions

Dante gives him. The letters XG form the image of Gambit from the

X-men (the guy who charges stuff with energy and the object then

explodes after a few seconds).

This image is graphic, but this is exactly how I memorize. I picture,

in left to right order, Billy the kid drawing his pistol and quickly

unloading all 6 rounds into Satan, who is trapped in the ice as in

Dante's Inferno. This doesn't kill Satan, but only wounds him. To

the right of Satan Gambit charges a playing card (his usual weapon)

and places it in the mouth of Satan. When the card explodes it

explodes Satan's head and blood and guts are thrown absolutely everywhere.

Yes this image is graphic, but because of that it was very easy to

memorize. Anything funny or violent tends to be easier to hold onto.

**********

BLAST DOOR

**********

Yes that literally is a blast door, like for a bomb shelter. I

imagine a 200 foot tall steel blast door dropping down onto my journey

in the space between the 3rd location and the 4th. I image that in

order to get past the door I have to fly over it as if I were in a

helicopter, and I literally picture this flight over the blast door.

This is my marker that the centers are now done - i.e. when I get to

the blast door during the solving phase, I know that what follows is

now information for the edges.

edge cycles:

1) (lBU -> fUR -> fUL -> lDB -> uFR -> fDR -> rDB -> bUR -> lUF -> dBL

-> uFL -> uBR -> bDL -> dFR -> rBU -> lDF -> uBL -> bDR -> lBU)

2) (rUF <-> dFL)

3) (bUL -> fDL -> dBR -> rDF -> bUL)

edge cycles as letters:

1) (Q -> F -> E -> S -> D -> H -> L -> M -> R -> U -> C -> B -> P -> X

-> J -> T -> A -> O -> Q)

2) (I <-> W)

3) (N -> G -> V -> K)

Location 4:

-----------

I am now memorzing the edge permutation. This location is at a "+"

shaped intersection of two very large walkways leading into one of the

quads on my school that is a very large enclosed rectangular space

formed by about 8 buildings. I can clearly see the open space of the

quad, as well as the two walkways at this location.

The letters at this location are QFESD. I need to know which piece

will be my main piece, or the one that will be the first piece in all

of my cycles, so I take the first letter "Q" and make it into an

image. The letter Q goes with the image "Queen". I now take the

letters in pairs after the first piece. The next two letters FE form

the image of a 10 foot tall Ferris Wheel. The next two letters SD

form the image of a 10 foot long Star Destroyer (like from Star Wars)

that is floating in the air about 6 feet above the ground.

In left to right order I see the Queen hiding behind a miniature

Ferris Wheel while a miniature Star Destroyer bombards it with lasers

and explosives of all kinds. The ferris wheel is on fire and so

decrepit it is about to collapse.

Location 5:

-----------

This location is part-way down a pedestrian walkway that goes into the

center of the large quad we are now in. I can picture a big tree and

a small wall to the right.

At this location I have the letters HLMRUC. HL stands for the Satan

as portrayed by Dante again. MR stands for Marvin the paranoid

android from Hitchiker's Guide to the Galaxy (as portrayed in the

movie). UC stands for a Unicorn. In left to right order I see Satan

frozen in the ice trying to frighten Marvin the android, who could not

be more unimpressed. Satan gets pissed off about this, so he posesses

a unicorn just to the right of (behind) Marvin and has the Unicorn ram

it's horn through Marvin's head, effectively killing him.

Location 6:

-----------

This location is the center of the quad, where the two largest

walkways meet at a sort of tall skinny "X" shape. I can see the

buildings on the other side of the quad as well as a very big tree to

the left at this location.

Here I have the letters BPXJTA. BP stands for a backpack which is

oversized (about 6 feet tall) and filled with 100's of regular sized

books. XJ is the image of Jubilee from the X-men. TA is the image of

a tank with it's gun turret pointed menacingly at the object next to it.

In left to right order I see a backpack lying on the ground, filled to

the brim with books. Jubilee is using her sparks to completely

destroy the backpack which is now on fire and billowing smoke

everywhere. Behind her a tank aims and takes a shot from it's huge

gun turret but Jubilee ducks out of the way just in time.

I normally stop after three images, but this time I see that the next

piece, the "O" piece, goes to the "Q" spot and completes this cycle.

Instead of starting at a new location I tack on my single letter "O"

image (Ozzy Osbourne) behind the tank, as if he were orchestrating the

whole incident of the tank firing on Jubilee.

This cycle is now finished. I know I am not done memorizing edges

though, because I have only used three journey locations, and the

average is 4 for edges. During the actual solve I looked around for

an edge I had not used yet when I spotted the two cycle (rUF <-> dFL)

or in my letters that is (I <-> W). Rather than start this image at

the next journey location, since a two cycle is always just one image,

I tack it on to the current location just behind Ozzy Osbourne, only

surrounded by curtains on both the left and right. This is my

miniature, within a journey location, form for the "BLAST DOOR". It

lets me know that the image within the curtains is a two cycle. I got

this idea from John Louis, so thank you very much! The image for IW

is a "Y-Wing" space fighter from Star Wars. Within curtains I imagine

the Y-Wing taking aim at Ozzy Osbourney (through the curtains) to take

him out and make him stop firing on Jubilee with the Tank.

REHEARSAL:

----------

OK so I know I have used a 3 locations, and a little more since there

are 5 images at my 3rd location instead of the usual 3. I know that I

am not done, but I have no idea how many edges are left to look for.

So I go over my images (just for edges). I sort of half use this as

rehearsal for my edges and half to just count them and find out how

many edges I have memorized right now. I counted 20 edges when I went

back through my edge images. I now glance quickly at the cube to see

that no edges are already in their solved locations - I saw none. So

I know that there are 4 edges somewhere to look for. I find them and

they are in one cycle, which I put at my last location.

Location 7:

-----------

This location is on the other side of the quad. I am very close to

the buildings that before were only in the background.

At this location I have the 4 cycle (N->G->V->K->N). I take the N and

make it into a single letter image, that of Chuck Norris. The GV I

put together as a giant Gavel, about 6 feet tall. Since I only have

one piece left, the K, I make it into a single letter image of Chris

Katan from Saturday Night Live.

In left to right order I see Chuck Norris roundhouse kicking a giant

Gavel so hard that it slams into Chris Katan and knocks him over.

****END OF JOURNEY****

I now know that I am done memorizing the centers and edges, since I

have accounted for all 24 edges. I now memorize the Corner

permutation visually and the Corner orientation visually. Then I put

on the blindfolded.

*************

SOLVING PHASE

*************

Solving the corners is pretty uninteresting I think, since you can

just use the same stuff as from the 2x2x2 or 3x3x3. The only change

is that you *HAVE* to use supercube safe algs (algs that don't rotate

center caps if done on a supercube).

Here is how I solved the corners:

Corner orientation:

y' R' U2 R U R' U R L U2 L' U' L U' L' followed by U' R U R' U' R U R'

L' U' R U R' U' R U R' L' U' R U R' U' R U R' L2 y

or if you don't prefer xyz notation the above is equivalent to F' U2 F

U F' U F B U2 B' U' B U' B' followed by U' F U F' U' F U F' B' U' F U

F' U' F U F' B' U' F U F' U' F U F' B2

Corner permutation:

1) UBL->DFL->UFL : D F2 L' B' L F2 L' B L D'

2) UBL->UFR->DBL : (L B' L' B)x3 D2 (R F' R' F)x3 D2

3) (UBL <-> DBR) and (UBR <-> DFR) : F2 D (L' B L B')x3 D' F2

Centers:

--------

Ok time to actually solve the centers now.

First location: Dan Aykroyd->Internet Explorer->Volcano

A->IE->VO

I start with Dan Aykroyd then I take the first image, Internet Explorer.

Those are the letters AIE which is the cycle lbU->ufR->ulF :

1) To solve I use the commutator: [f' U' f, u']

I am here using the same notation I learned from Stefan and Per. [f'

u' f, u'] means to perform the first part, then the second part, then

the inverse of the first part, then the inverse of the second part.

So [f' u' f, u'] = (f' u' f) (u') (f' u f) (u) = f' u' f u' f' u f u

2) After Internet Explorer comes VO. So the cycle is now A->VO or

lbU->rbD->drB.

lbU->rbD->drB : D' r' [U', b d b'] r D

3) Aykroyd->Web or A->WB or lbU->lfD->rbU : [b' R' b, l2]

4) Aykroyd->Quaich or A->QC or lbU->ubL : [U, l u' l']

5) Aykroyd->San Francisco or A->SF or lbU->dbL->urF : L2 [f U2 f', u] L2

6) Aykroyd->Billy the Kid or A->KD or lbU->dfR->rfU : [U2, b d2 b']

7) Aykroyd->Satan or A->HL or lbU->drF->bdR : [r U2 r', d']

8) Aykroyd->Gambit or A->XG or lbU->rfD->dlF : r2 [b d' b', U'] r2

Centers are now solved. Notice that only three of the three cycles

required setup moves. One of the three cycles required two. Average

number of setup moves needed before being able to perform a commutator

was 4/7 or 0.57 moves.

Ok now I realize that I have run into the blast door. So I know that

the next stuff I recall deals with edges.

Edges:

------

The first location has me recalling Queen, then the very next image is

a Ferris Wheel.

1) Queen->Ferris Wheel or Q->FE or lBU->fUR->fUL : [R B' R', f]

2) Queen->Star Destroyer or Q->SD or lBU->lDB->uFR : R [U', B d B'] R'

3) Queen->Satan or Q->HL or lBU->fDR->rDB : [B2, U' f2 U]

4) Queen->Marvin the Paranoid Android or Q->MR or lBU->bUR->lUF : F'

[B d' B', U'] F

5) Queen->Unicorn or Q->UC or lBU->dBL->uFL : [L2, F' l2 F]

6) Queen->BackPack or Q->BP or lBU->uBR->bDL : [U b2 U', B]

7) Queen->Jubilee or Q->XJ or lBU->dFR->rUB : l [B' d B, U2] l'

8) Queen->Tank or Q->TA or lBU->lDF->uBL : F2 [U2, F' u' F] F2

performed as F2 U2 F' u' F U2 F' u F'

9) Queen<->Osbourne and Y-Wing OR (Q <-> O) and (I <-> W) or (lBU <->

bDR) and (rUF <-> dFL)

Done as two three cycles

9a) [r' D' r, U2]

9b) [U2, B d' B']

10) Chuck Norris -> Gavel or N->GV or bUL->fDL->dBR : [b' R' b, L2]

11) Chuck Norris -> Chris Katan or (N <-> K) This is edge parity. To

solve I did:

f' D' f y' r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2 y f' D f

The cube is now solved.

The three cycles averaged at 4 setup moves in 11 cycles or 0.36 setup

moves per three cycle. Parity used 3 setup moves, which is probably

average. A lot of cases require 4 setup moves if you want to preserve

centers. If you don't mind not preserving centers you might average

2.5 setup moves for parity.

-----------------------------------------------

Hope this helps. I tried to include absolutely everything, and

looking back over it that is how a BLD solve feels to me.

I double checked this message about three times, and the solve and

scramble work. If you work through the solve and it doesn't work try

again, because I double checked and there are no typos in the scramble

alg or in the stuff about solving.

Chris - Great post... my only question is why you do not do the corners last?

I've tried memorizing the 4x4 or 5x5. I'm finally "trying" to learn

OLL and the G Perms. Once again, though, Blindfolded cubing is

taking precedence.

I agree, why solve the corners first? However, I'm not confident in

my big cube blindfolded abilities yet. So I don't know why you've

chosen this way. Perhaps it just feels better. Just as different

memorization methods feel better.

I did just realize that he's posted before about blindfold solving a

cube and he messed up the Corner Permutation, when the rest of the

cube was perfect. So perhaps he'd rather use short term memo for

his corners in BLD.

> - I took the time yesterday to make several blindfolded attempts on

the 4x4 cage. I believe I made three. I sat down to memorize one

and I was distracted by a mediocre chore, so I stopped. My Second

attempt, I spent about 13 minutes memorizing the cage and I go for

the solve. I had the scramble perfectly memorized. I start corner

permutation first, and I messed up the exectution of my first corner

alg. I was doing the left handed Y perm. And everything just felt

wrong! I stopped then and there ); ... My third attempt I did at

my grandmother's just before work. Memo 16 minutes; Execution 13

minutes. I recalled everything perfectly. There was no 3x3 or 4x4

parity. However, I messed up a setup. Once again it felt wrong. I

tried to fix it. The error occurred in the last 6 edges. It was so

close! I have a long way to go. There was one cubie I was lost on

during the final execution. I recalled the chess game. I recalled

the accelerated math class lesson. After permuting 15 cubies I

start a new cycle. I started at lUB.

So I recalled:

"Skip to Mu; Dragoon" ... very long pause ... another pause ...

ohh, "Dragoon becomes King." "Lamba, Ace, Galanoth, Mu" Solved

The rUF was permuted by default, that's my 4x4 reference point. The

lUF was solved too. Resulting in 21 permutations + 1 new cycle = no

parity. I was glad that I was able to recall the King image.

That cycle equals:

Skip to lUB; fUL->rDB->lDB->rUB->bUL->lUB;

Haha, I just realized another life adventure. I can cause my images

to have accidents that my families experienced. Such as my 3yr old

sister cutting all of her hair off, or my getting ran off the road

last week. A brother getting injured on 4th of july.

Later,

Hey Marcus,

> Great post... my only question is why you do not do the corners last?

I've just found that I really like solving them first so during

memorization I can just barely memorize them, just long enough to put

on the blindfolded and solve them.

There is one major downside though, if I get corner parity, I have to

wait until after I solve the centers before I can fix it since an odd

permutation on the corners must also perform an odd permutation on the

centers (supercube-wise).

I've found though that if I use auditory memory to help me remember I

have parity in the corners it helps a lot. Once I know I have corner

parity I literally say out loud "corner parity" and I have found that

it usually sticks in my mind long enough for me to finish centers, and

still remember that on this solve (not the one before) I have corner

parity, since it's still ringing in my head so to speak.

It's just a personal preference, I know solving them last would be

fast too, since I wouldn't even have this corner parity problem, but I

prefer to do it this way after trying both.
