One-Answer 3x3x3 Question Thread

[FastCubeMaster]

If 3 corners need to be rotated, all 3 will need to be rotated in the same direction (all 3 clockwise or all 3 counterclockwise)
If 2 corners need to be rotated, then one will need to be rotated clockwise and one will need to be rotated counterclockwise.
If 4 corners need to be rotated, then 2 will need to be rotated clockwise and 2 will need to be rotated counterclockwise.
Edit: if you get a case other than those above, physically twist one of the corners to match one of the cases.

Exactly.
The confusion here was that when Brest said: "It should be easy to twist it back," he meant physically, not algorithmically, as JustAnotherGenericCuber pointed out

(sorry guys, the pics inserted in the post above)

I appreciate everyone's responses, thank-you.

I can't for the life of me figure out what I am doing wrong. Attached are 4 pics.

Pic 1 was the state of my cube, the '3 corners' scenario JustAnotherGenericCuber mentioned above.

So I held the cube with the blue side facing me, and performed this algorithm:

1. R’ D’ R D (2 or 4 times, can't remember)
2. When the colors were oriented correctly, a single U' (clockwise turn of the upper layer of the cube)

Pic 2 - The state of the cube after completing the above. I then repeated the same algorithm from step 1, followed by step 2, an upper layer clockwise turn (same direction as previous), always while keeping the blue layer facing me. This lead me to Pic 3 and eventually Pic 4.

Pic 4 is the final state of my cube, and as you can see, the yellow layer is now fully solved but the rest of the cube is completely wrong.

I have a feeling I'm doing something so obviously simple to fix.

To go one step further, I re-scrambled the cube. Luckily 3 of the 4 corners were solved correctly with only the red/yellow/blue corner square being oriented incorrectly - first pic below.





With the blue side facing me, and this unsolved corner in the top-right corner, I then performed the algorithm below 4 times:

R’ D’ R D
​

Below is the final state of my cube. Red/yellow/blue now oriented correctly, the remainder of the cube still unsolved.
This is the most basic algorithm - how can I possibly be doing that wrong?

I'm about to give up on this.

It's impossible to only have one corner twisted by using normal moves. What's happened is a corner has been physically twisted in place by accident, which sometimes happens when your turning is inaccurate. The only solution is to hold that corner piece and twist it back again. After that, your cube will be solveable.

UGH... Now I understand. Physically turn the piece because I must have somehow previously physically twisted a corner in a way that made the cube unsolvable, correct?

I physically turned the corner pieces to solve the cube, scrambled it, and now can solve it.

Thanks very much for all your help!

Got it, this makes complete sense!!! Thank-you so much all.

I have been dying to know which part of CFOP has the highest impact on your time and which part should you be practising the most of?

 

[shadowslice e]

Probably the F2L though you should have good lookahead between all stages.

Thanks bruv good thing I have learnt 24 F2L algs so far but am now on moving to full PLL since someone said that it would be best to do full PLL which I have learn 7 10 of so far. Would this be a good move now since my F2L is decent.

I don't recommend learning algorithms for F2L. It's generally best to keep it intuitive; this way, you understand each move you make and can change certain ones when applicable.

Hi, guys. My avg now is 33-35, i know all plls except g-perms, intuitive f2l and about 25 oll algs and 2-look oll. I`m planning to buy a new speedcube. I was thinking about The Valk 3, but now I`m thinking worth it to buy such a professional cube, if my time isn`t very good.

Question: Would Learning Full OLL for 3x3 make you Sub 20 to sub 15? Thanks.

Question: Would Learning Full OLL for 3x3 make you Sub 20 to sub 15? Thanks.

It would help, but you don't need full oll to be sub 15

 

[PHrez]

What about if its 3 edge pieces, like shown?

The only reason to buy "beginner" speedcubes is if you don't want to spend the money it costs to get a higher end cube. There is no reason why someone starting cubing should start with a cube that has lower performance. You'll probably upgrade to a better cube later so why not now.

We can't see those pictures, but if you're asking about when you have three edges cycled, then that's solvable. If you're asking about when you have three edges flipped, then that's not solvable.

Thanks! I'll this more often!

It would help but you don't need to.

Though tbh you can get sub-15s with beginner's so really you should probably learn it.

Hi guys, still on the cusp of sub-20 here, nearly there.

anyway, I only know one algorithm per pll and I'm just looking at learning a few more so that I can solve some plls "from the back" without the need for a U2 beforehand.

Can anyone please list which plls it is definitely worth doing this for?

I'm starting with the U perms.
