Blindsolving Discussion and Help

M2 question: Regarding the FU/BD and UF/DB interchanging. You can either a) Notice if it's first or second in the letter pair and use the inverse algorithm if it's second. or b) Memorize e.g. FU as BD during memo and not worry about choosing the correct algorithm.
Which method is better? (Multiblind)

I memorized them normally and switched them during execution, this way your memorization is the same as if you were using 3-cycles

How do you memorize the notation?

How do you memorize the notation?

What notation? Regular Rubik's Cube notation or the Speffz scheme (or something else entirely)? Speffz is easy; you just start with the UBL sticker for corners and the UB sticker for edges and go around clockwise from A to D. Then you do the same thing with the L, F, R, B, and D sides in that order, for a total of 24 letters.

Speffz. I understand the notation, it just seems time consuming to go around the cube saying the ABCs every time you need to figure it where a sticker is.

You need to eventually have every sticker labeled - might as well follow a standard. After a few hundred solves you'll instantly know where each piece is by letter. And once you do, you'll be hopelessly attached to whatever your sticker color scheme is for life. That's why I'm stuck with mine, anyway. And my labeling isn't Speffz either because when I learned, Ville hadn't even started cubing yet, much less started working on a labeling system.

Don't worry about that. In a pretty short amount of time you'll be able to instantly know where any letter is on the puzzle, recently when i've been listening to music i have been trying to imagine a cube, and every first letter of a word, seeing where that letter is.

It's quite fun to be honest.

A good strategy is to start by remembering the first letters on each face, so A E I M Q U then count from there. Counting up to four letters is much easy than starting from A each time. With practice, you start to remember the individual letters too. I never made a coincious effort to remember them.

Some people get an old cube and write the letters on, or put lettered stickers on. Just while learning of course - as others have said, after some practice you won't need to think about it any more.

Hey everyone, I have a question about 5BLD. I've only had one success in my life out of four attempts, and on my last unsuccessful attempt I was off by 3 T-centers. It was for the Speedsolving weekly competition, so if you haven't done the first 5BLD scramble yet and plan on doing it, don't click the spoiler:

Spoiler: first weekly comp scramble/reconstruction

Scramble: Fw' L2 D Uw' B2 D' Dw' Bw' F2 L2 Bw' Fw2 F' Dw2 R2 D' Uw U F' Lw' Uw2 L' Lw Rw F L Lw2 Bw2 Uw' Bw R' D Fw Dw Lw Bw2 Uw' Bw Fw D2 F' L Rw2 B2 Bw' U2 Bw' Dw U2 F2 L2 B2 Bw' Fw Rw' R' Uw' L D' Dw

Inspection: x' y

So, I memorize T-centers last and solve them first using U2, so here's the memo I had (Speffz scheme): UE CM VG QN DW JO RL SI HX J

After executing it and the rest of the solve, the B, M, and W (lol BMW) centers were unsolved. I tried doing it sighted afterwards and the A, M, and W centers were unsolved (probably due to center-unsafe algs I used later in the solve), but the issue still stands. I don't see anything wrong with my memo. I think it's happening somewhere around the C... is there a special alg that I'm supposed to use for that? I currently use M u M' U' M u' M' U' M u M' U2 M u' M' U2.

Anyway, I'd really appreciate it if someone would explain this weird error to me. Thanks in advance!

So I've been learning old Pochmann blindsolving for corners (just had my first successful blind solve). On his site there is a formula which says

"#items_to_memorize = (#wrong cubies) + (#cycles) - 2".

I solve green front and white top. If the URB, URF and ULF corners have cycled clockwise my memo is "CBAC".

I would say this memo is one cycle. However following the formula I conclude that it is actually 3 cycles. What am I doing wrong?

This is 3 targets. I wont claim to know exactly what that formula means or even the practically usage of it. But by my understanding this is 1 3cycle and one remaining target. But this can be seen and done as 1 cycle... It's a pretty advanced cycle.

This can be done as an edge cycle with an AUF because all the corners are technically permuted relative to each other bringing the amount of "wrong cubies" to be only 3, the ' UR, UF, UL' edges and all the corners just need a U' to be permuted. So you would solve the edges and then permute the corners with the U'. It is an advanced case but that can explain the formula.

What is the best way to memorize a lettering scheme?

What is the best way to memorize a lettering scheme?

The best way honestly is to just pick a scheme at the start, and stick with it (make sure you stick with a fixed solving orientation too). Just do heaps of solves (can do sighted) and it'll slowly become second nature. A way I like to look at it is that I associate a colour with a group of letters, for example I solve yellow top blue front, so if I were to look at LB, I see an orange sticker and immediately think the letter must be either E, F, G or H and you can quickly deduce the rest from there. Of course, as you become more accustomed to the scheme, you just look at the piece as a whole and immediately know what letter it corresponds to.

What is the best way to memorize a lettering scheme?

I got an old cube and wrote the letters on all the pieces. Then made flashcards, one for each sticker (the letter and then either "corner" or "edge"). And then I would go through the flashcards, put the desired sticker in the optimal position across from the buffer without looking at the cube, and then check if I got it right. Study as needed.

I wonder if this should go to "Other Questions" thread, but:
What does "Speffz" stands for?

Good question! It's named after the usernames of its two creators: Ville Seppänen (Spef) and Rob Holt (Riffz).

Exactly the same as corners on a 3x3

I've never learned how to solve a 3x3 BLD.
