Official Blindfold Algorithm List

[joey]

Yeh, it's just a simple corner commutator! Good you found it yourself

 

[Scigatt]

I didn't find it myself, it came from the beginner's solution I learned.

(R U' R' U' R U'2 R' U')2 : LUB - RUB, RUF - RDF

Don't know if it's useful for you freestyle cuber..

And after add a z turn as setup : z (R U' R' U' R U'2 R' U')2 z'


Btw, is it possible to find 2-gen algorithms by cube explorer or any other programs?

Yup. Cube Explorer and ACube are capable of finding n-gen algorithms. And it's quicker to find a 2-gen alg than a 6-gen one with either program in case you didn't know. I can't find slicing algs using Cube Explorer though.

Thanks, but...how? XD
I'm using cube explorer 4.30, and I can't figure out how to do it

Don't define your cube completely, e.g. leave one corner blank.

* Note that these algs twist the DBR corner instead of the DFR corner like all the other algs do

When I say optimal, I mean 2-gen optimal, I don't know if these algs are 6-gen optimal, but I'm guessing most of them are.

Parentheses are not meant to indicate regrips, they're meant for easier learning of algs by "fingertrick groups". Most of these algs require at most one regrip. And there are lots of Air Jeffs and U'2s. I can't do left index-middle double triggers, but left index double flicks work fast enough for me. I also do right thumb followed by left index for some of the U'2s.

I can sub-2.5 on average for every single one of these algs, some are even sub-2, so they're not slow

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

Edit:
This is how CO works for me...
If more than 1 corner misoriented on U
1. Look at U, identify case. Place finger on affected D corner, if any.
2. z2 rotation, look at D, identify COLL case.
3. Don blindfold, orient D.
4. z2, orient U, done.

Why this way? I'm much more familiar with my COLL algs, so once I identify them, I execute them instantly. While executing them, I have time to think about the U layer alg which I may not be as familiar with.

I learned "all 4 directions" for most cases because AUF is something we unknowingly waste a lot of time trying to visualize, memorize, recall, and execute. How many times have you done some alg that starts or ends with some kind of U turn, and end up doing U3 instead of U', or U-pause-U, instead of U2, because you were *thinking* of the AUF? BLD is for braindeads.

Also, all those annoying cases with 2 corners misoriented on U (which are not COLL cases) are essential. This guarantees a one-look-at-U, one-look-at-D, no-funny-cube-rotations, minimal-AUFs CO system. With this system, the entire memorization + execution process of CO should easily be sub-10 with less than a week of practice. I found most of these algs yesterday and I'm averaging 11.xx now.

Oh, and...
If 1 corner misoriented on U
1. z2 rotation to D, identify case, take note of AUF and ADF.
2. Don blindfold, orient, z2, done.

There's a reason I switched to 2-gen, I really HATED identifying those stupid cube rotations ALWAYS took me like 5 seconds or something just to identify the case, with these algs I just treat all 6 as separate cases and identify them in a glance I can sub-2 with all these algs. Bet you can't with a cube rotation before and after

I might if I'm crazy enough. One-look CO + 5-cycles just might be able to beat freestyle That's super advanced 5OP... 2x2x2 BLD (or maybe even speed?!) just got a whole lot easier :rolleyes:

No I can't That's true
Probably I'm just too lazy to learn new algs.. I'll try

but...well, I can't find an easy 7 or 8 flip alg...*sigh

Considered color neutral CO?

[blah]

what O.o? Sry I don't understand..

I haven't had time to find a proof (or disproof) yet. But I *think* it's possible to have at most 6 (or fewer) misoriented corners if you are color neutral, i.e. choose the best setup move restriction groups among UDR2L2F2B2, U2D2RLF2B2 and U2D2R2L2FB.

oh I get it...but it doesn't seem good to chang setup moves while inspection
It waste few seconds thinking..instead of it I can already do 1 or 2 algs

are there any faster one?

I just do an F' or B setup move then do either Headlights or Chameleon.

 

[cubeRemi]

since I quit cubing I thought I'd post my 3x3 "method"/algs here:

it is a pure 3 cycle method. most of the algs are commutators, but you learn them like algs in order to do "permutation time attacks".
it's a bit TuRBo like (lot of same cases), only more to learn and (I really think) faster.
it's almost as few moves as pure freestyle, only you can do time attacks.

corners, average number of setup moves: 15/14 or ~1.07
