[Help Thread] 4x4 Discussion

[SenileGenXer]

I'm not always doing it I'm just attempting to do it and then cleaning up what I need to.

I'm trying to set up 4 (or 3) pairs to be solved by the first Uu slice and then swapping them out for 4 (or so) pairs solved by the U'u' slice back. The back slice is more important to game out and you can almost see exactly what's gonna happen at a glance by looking at the pairs to be done; they are what's on the up layer of the cube after that first slice plus what you didn't manage to do at first.

If i need to clean up - and that is often - I do the flipping alg for two pairs (most common scenario) or I do 3 at once.


Edit. if you can inject one presolved pair into it (say preserved from the time you make your final cross piece) then you have a really good chance of being able to do a 3-4 knockout.

when I solve the last edge, I don't do it so that the centers are solved. I make sure that the centers are off by a u(') turn so that I can easily step into 322... whatever it is lol i don't count. I just do the first three and then solve one at a time using the two slots on front till I'm done. The thing I have trouble with is the pairing cross edges after the first 2 centers, not the actual moves, but finding the freaking things...

i think it takes more time to look ahead and pick edges that will cycle nicely; like it's not that difficult to just adjust and do two edges instead of three, for example. also you can move edges around that are on the E slice? Like if you're looking for your first edge pair piece and it's somewhere else on the E slice, you can just take it out and put it back in.

It's worse when the edge is trapped in the E-slice after you've started pairing. Although it can still be recognised and recovered quite quickly.

I would love to see a good video about building the last 4 centers using Yao with white on left. It takes me for ever.. In my old reduction method I take only a few seconds.

I solve 3 half centers, by having a pair made on the left, and uses the remaining center like a buffer to form up the remaining center pairs and insert them.

I learned it from Yoshinators video.

Cool, I will watch tonight after work. Thanks.

I have this video: http://www.youtube.com/watch?v=lO5JrGVXfww

What I try to do is not simply building one center at a time but also solving some center bars on the left if possible. I think if you do some slow turning solves trying to solve efficiently would help alot. In the end, it is propably just practise

I like that. I do it cyoubx way for the last cross edge which straightens out the centers but if you don't and keep them skewed then you can jump straight into the E layer 3 edge pairing.

So it seems to me from the responses is that there is no 'canonical' method for doing the last 8 edge with Yau and you do it the way that suits you best?

It went too fast, I did not understand one bit of it.. LOL

Nice video. You are right, I must do some slow solves (a lot)

 

[Schmidt]

This only happened once using Yau:
After cross and all centers I did a Uw. First pair solved, y', second solved, y', third, y', last solved too, R U R' y *4 and slice back to be done with edge pairing. Nice feeling , but still a slow solve .

It´s explained here as well, and also in one of the top comments.

How are you solving 4 pairs with one slice? I have that happen only occasionally by luck.

I put up a how to video

I'm stuck at around 1:40 average using Yau method. My cube is a Maru 4x4x4 with Super Bright stickers, lubed with Maru lube + Lubix.

I know the best way is to practice, but should I rule some edge pairing methods completely? I'm using Yau because I find it much easier to find pairs when one layer is ruled out. I've tried 2-3-4 and 3-2-3 pairing. Anything else I should know about? Should I consider buying a new cube? When doing centers in Yau is it better to for pairs first or complete centers 1 at a time?

My goal atm is to average 1:30 and eventually sub 1min the 4x4x4.

Also the edge flip parity takes me like 7 seconds at a good speed. The algorithm I use is RW2 B2 U2 LW U2 RW' U2 RW U2 F2 R F2 LW' B2 RW2

Search for my channel on YouTube - Bhargav Narasimhan. I've a video for finger trick for another OLL parity.

This one? Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw U2 Rw' U2 Rw'

It certainly has a better flow to it than my previous alg, thanks for the tip!

Unexpected problem solving 4x4. Last corner pieces are wrong.

After learning the 3x3, I decided to get a 4x4.. I soon worked out how to get the centres and then the edge pieces.. And then I realised that I could finish it like a 3x3 (using the Dan Brown method).

A few minutes later I was on the last moves, but couldn't get the corner pieces right. 2 of them were always swapped over. I assume that this is a quirk of the 4x4, as I have never seen this on a 3x3.

Is there a way to fix this? I assume there is an algorithm, but just wanted to check that I havn't overlooked something else.

Sorry if i am being dull, but what does the "w" refer too?

I watched a video which showed the parity corrected on the top face.. This might be wuicker, but i just want to be able to do the 4x4 without having to learn too much more than i already know. Can i just work through the cube until i get to where i am now and correct the parity at the end?

The 'w' means turn two layers at once. So Rw is the two right layers.
