How to solve a Rubik's Cube BLD + Progression

[Noahaha]

What do you mean "the wrong way"?

I understand this, I just don't understand how you know which one to use.

I think you need to watch these tutorials a little more, but I'll try to explain.

A flipped edge in a scramble is just like a flipped edge in an almost solved cube. It's between the correct two centers, but it is "flipped"

You always setup to RFD in OP because that is the sticker that the Y-perm targets.

The stickers are in the wrong places, for example, the two edges in the image below are flipped.



The pieces are in the in the correct spot, but the stickers are not, the pieces are said to be flipped.

I just don't understand how you know which one to use.

FR and RF are both stickers of the same edge piece. In the image below, the FR sticker is blue and the RF sticker is red.

They are in the in the correct spot, but they're not oriented (flipped).


FR and RF are both stickers for the same edge piece. In the image below, the FR sticker is and the RF sticker is

Your images are a bit off I think.

I'm having a lot of trouble with the flipping and twisting.
And how do you know if you have a flipped/ twisted piece?

There is a trick how to determine if you have a flipped/twisted edge.
Let's denote that a cycle is good if it starts and ends at the same sticker. For example, UF>DB>DR>RU>UF, or UL>FR>UL, or just an edge standing on it's place.
A cycle is bad if it ends on another sticker: UF>FR>FU, UR>BD>LF>RU, or just a flipped edge.
Then, the number of bad cycles is always even. So during memorization you count a number of bad cycles (or just their parity; you can just bend/unbend a finger each time you have a bad cycle). If after a memorization the number is odd, then there is a flipped edge somewhere. If it is even, then there is no flipped edges, or 2 of them, but in the latter case you will feel that you've memorized too little.

Similar trick can be used with corners (though I use it only in multi and big cubes). If a cycle ends on the same sticker it starts, let's associate 0 with it, if it ends clockwise from where it started, then 1, if counter-clockwise, then 2. The sum of all associated numbers must be divisible by 3.

it was the easiest tutorial for me to follow

I'm confused as to why the Y-perm swaps ULB and RFD? I thought y-perm swaps ULB and UFR? Is this to preserve the placement of solve pieces?

The Yperm that swaps ULB and RFD is done without the first F and without the last F'

Great tutorial.
I think I will learn not blind 3x3x3 better, to get cube (position of colors and precision of moves) better and then I will try blind

That Yperm, can someone please post the alg?

 

[Username]

That Yperm, can someone please post the alg?

(R U' R' U' R U R' F') (R U R' U' R' F R)

Or you can just do a setup move (F') Do a regular Y-Perm and undo setup by doing F. That still cancels out to the alg above

I just wanted to post this: Are you tired of doing "M2"? Well, do ((R)19 r)2 And everything is good
Just use M2 for edges an R2 for corners

 

[DrKorbin]

R2 for corners

You mad

 

[IQubic]

You mad

I do not understand, isn't R2 a good corners method? That was my impression,but what do I know, feel free to correct me if I am wrong

It has almost the same move count as Old Pochmann, but more complex.

Any help on how the corner stickers move because if i do a corners only attempt some of them are twisted and its not the twisted corners only once i shoot the pieces they are twisted

Think of the cube as stickers rather than pieces. So instead of thinking "Ok shoot the UBL piece to RFD, think ok the green sticker UBL needs to be swapped with the red sticker on RFD"

If you have an already twisted corner, I think of it as "UFR clockwise".

The problem is that the setup moves for geting the peice to the RFD sticker
sometimes i lose track of what the setup move is and i mess it up

Practice all the setup moves 10 times, and you should be good.

looks like i'll have to work on it
