Hello,
I'd like to get a large list of Blindfold algorithms. Please post all the ones you know here, for simple tricks, to the more difficult stuff. Please post the alg. and what it will do (or post a diagram [preferred]). Diagrams will be added overtime as they are created. I will edit this post as we go. If you are going to add more algs after you have posted once, please create a new reply so I know that you added more. Thanks

Check out these algs, I try to use them to fix the parity. It's possible to use this alg set after the Orientation steps of a BLD 3-cycle method to fix the parity. Or it can be used at the start of a 2-cycle method to fix the parity.

I'll not go into detail as to how to apply them. But, I see power to them. Maybe somebody else will too. If anybody is curious, ask me, contact me at dbeyer816[at]yahoo[dot]com

We will be posting some up as they come. I need to add yours you listed awhile back.

what happened to that 2 cycle list?

I found this 8 edge flipping algorithm when I was messing around with my cube. It flips edges on the F and B faces. It can also be modified to do only R and L edges or U and D edges.

[R L F B U D] x 2

Macky recommends to do that alg like this, making execution a bit easier:
(r R d D)x3

where lowercase letters mean a double layer turn.

They're the same alg, just a different way to execute them.

I also developed some interesting variations of this alg too:
flip top 2 layers:
M2 u (l L u U)x2 l L U M2

flip bottom 2 layers:
M2 d (r R d D)x2 r R D M2

where lowercase letters mean a double layer turn.

Those are great algs! Now I can do EO a bit faster when the setup is easy or no setup is required.

I found this alg recently. It's quite fast; did it in 1.93 seconds. Twist UFR URB UBL:

R U (R2 U' R2 U) (R U R' U') R U R U (R U' R' U)
Hey Joël, that is a nice alg. How did you find it? The reason I ask is that I am curious if there is a maybe slightly less optimal version of it that is also supercube friendly, since I would need something that flips corners on the bigger cubes BLD before I have solved the centers.

Nice alg though, I will definitely try to learn it for 3x3. If you have any ideas on how to make it supercube friendly that would be neat for bigger cubes!

This is supercube friendly:

R U' L' U u R2 u' R2 U2 L U' R U'

I am glad you like it. I found it with Acube . No idea how to make it supercube friendly... Sorry

Johannes' alg is optimal btw.. Not sure if you'd like those u moves on a 4x4, though...

Chris,

Since you asked for a supercube friendly alg for this case, I spent some time searching for an algorithm, and this is what I could find after playing around with the RU'R'U move for a while:

(F' U' F2 R' F' R2 U' R' U2)* 2

18 moves.. same as the other alg. Maybe not the fastest alg... But it works .

Edit: It's executes pretty nicely on a 3x3, actually.. Sub3 after a few tries .
Edit2: In case you wonder how I found this, I basically used RU'R'U repeatedly, putting cuberotations between them: (RU'R'U xy) * 6. Then I rewrote it without the cube rotations.

One I discovered while messing around with COLL:

B (R U R' U')x3 B' (1 5)(2 6)

Can be also used for (4 8)(2 6) if you switch B and B'
