One-Answer 3x3x3 Question Thread

Where can I find those 6-9 moves?

You can’t really document them, there’s loads of possibilities in cross.
As it is, cross is the only part of CFOP thats vaguely intuitive at a high level. Maybe you could try one of those cross trainers, which give optimal solutions for scrambles, and learn the technique (rather than the individual moves)

I was just stating that on average you can solve the cross in 6-9 moves. It is different every time. It is not algorithmic like last layer.

I wold really try and get to a point where you can do all 4 every time and by memorizing the 6-9 moves necessary to resolve it. I’ve spent the last month heavily practicing cross, over 500+ cross only exercises with no timer and I recorded my move count in catimer. Sometimes you get a really bad scramble and I need to spend a few minutes working out a solution mentally. It’s hard work and not always a lot of fun but the rewards are starting to show up in my times solves.

I also used to struggle with on out being able to get partial cross solutions but with lots of diligent practice I'm seeing positive results

I had a spreadsheet where I would try different solutions but I didn't think that was useful for practice

I have a rubik's connected and when I plug it in with USB to a laptop, the blue charge light comes on for a few seconds, and then goes off. Is this normal?

Basically just keep taking it off and putting it back in. Try pushing it in harder as well.

This is mainly focused on 3x3 cfop and roux last layer:

I know it depends on who is doing it of course, but anyone who is proficient in both methods should know.

Is cmll faster than full oll/pll? I know there are more advanced coll and other things things, but as I understand it most use cmll in roux, but I may be wrong...

I know move count factors in.

I use cfop and have dabbled in roux, but just wondering how these two compare on last layer.

cmll is faster than CFOP last layer, but you have to compare cmll+L6E to CFOP LL to make it a real debate

 

[Swagrid]

CFOP and Roux are hard to compare as they share nothing in common, but comparing just CMLL to LL is unfair. as DNF_Cuber said, you'd have to include LSE.

I think it heavily depends on the person. Some people will be faster with CFOP LL, and some people will be better with the more intuitive nature of LSE, as well as favouring the fingertricks.

The 3 top methods are so close in theoretical optimal speed that I think it mostly depends on the solver picking the method that suits them and their skill set the best

I guess since I'm fairly ignorant of Roux that I phrased it as a "last layer"... I guess I really meant the last part, the cornrrs and edges after the blocks compared to LL of cfop.

This might be the wrong place to ask this, but how do I get my PLLs under 3 seconds? Most of them are but no matter how much I practice, my G and N perms aren't. (I'm using https://bestsiteever.ru/pll/ to practise them).

Use good algorithms and fingertricks, and drill them. I have a video on the old PLL's and fingertricks I used to use, which are all consistent and sub-1-able.

more than just repetition, you need to make sure you are executing the fingertricks right. Think about your algs like Wrist R' -> Push U', etc.

You could try different algorithms dor the same case. I recently changed a couple that just never flowed well for me.
Here's a website that some here recommended to me.

AlgDb

algdb.net

The same algorithm from a different angle makes a world of difference. I never could get with one of the most popular sunes, but backwards worked really well for me.

Fingertricks also can be the differnce between an ok alg and a great one.

You need one that us so comfortable your fingers feel natural doing it.

There are plenty to choose from.

How many people do you think are sub 10 in the world on 3x3 ?

 

[the dnf master]

There are (as of Mar 26, 2018) 908 people in the world with an official average under 10 seconds.
got this from quora
but now, my guess would be low 1000s

 

[Rubuscu]

Is it possible to average under 20 seconds without good fingertricks for PLLs?

 

[xyzzy]

Is it possible to average under 20 seconds without good fingertricks for PLLs?

Yes, but refusing to learn the good fingertricks is just making it harder for yourself.

(You can get to like 10 seconds even with lots of bad habits, provided that you have sufficiently good lookahead and moderately high turning speed.)

 

[carcass]

Including all 8 corners, how many possible CO combinations are there? What I mean is only white and yellow, and if they were all facing straight up or down I would consider that oriented(think Guimond on 2x2).

 

[the dnf master]

Does this OLL fall into the all corners oriented category or the dot shape category?

Technically both, but most cubers consider it a dot case
