[Help Thread] 4x4 Discussion

[greentgoatgal]

Hi guys, trying to get sub 40 and looking for some tips.

I know yau and currently average 44-45.
I can predict at least the first center in inspection.
My cube is a poorly lubed thunderclap mini, I just ordered a wuque mini m.
I'm sub 10 on 3x3.
I know like 5 last 2 edge pairing algs, and maybe 10 special OLL and PLL parity cases.
I just learned the left flicking OLL parity finger tricks.

Any advice would be amazing

i suck at 4x4. i need some pointers on how to improve past 3 minutes(im that slow) with yau. Thanks in advance

Turn less, pause less, and turn faster. (In roughly that order of priority.) Good hardware can also easily cut 10% from your solve times if you've been using a mediocre budget cube.

(Hint: you can get more specific and personalised advice if you provide more information, e.g. how fast you are on 3×3×3, a solve video, etc.)

i use a stock wuque. non magnetic not lubed not mini

I am super duper new to the cube scene (as in, a week), so I'm still trying to figure all this out. I have the 3x3 down, but I'm having a strange issue with my 4x4 cube, and I'm not sure how to fix it. Maybe I'm missing a step or something, but I have no idea what to do. I have the white and yellow centers done, as well as the green and blue. But the red and orange are being stubborn. (I can't seem to add pictures or video though? Halp)

It is possible that I've done something weird to the cube, as I messed up an OLL parity algorithm late in the game and had to start over. That and my general stupidity are the only causes I can guess at xD

If someone could help, that would be great, because I've been troubleshooting for like 2 hours! I'm a baby cuber after all haha

If you upload a video to youtube you should be able to link it here. Drag and dropping pictures usually works for me too.

You're being a little bit unclear with what is wrong with your cube; you just said that the red/orange centers were being "stubborn".

If you can't figure out how to add a picture, you could try re-creating your case on alg.cubing.net. We won't be able to help anymore than that until we know more information.

I posted a video! Sorry it's so quiet. I had to whisper :3

And when I say "completely unsolvable", I'm being a little hyperbolic. But y'know.

And thank you for reminding me about my phrasing. I had originally written the thread to go with my video, but I couldn't upload it, and didn't change the language

I have a Wuque too. Out of the box I found it terrible. I put a truckload of lube in it and now it's really nice.

Hint: try messing with double-layer half turns + turning the red and orange faces.

(Full solution.)

Thank you so much. I've only just picked this cube today, so this has been a big help

 

[AbsoRuud]

Just play with 2Rw and U or U' moves and you'll get it.

 

[AegisSharp]

General tip: its easier to finish on 2 adjacent centres as you can see both of them right in front of you while doing it.

 

[MisterRogue]

That's how I did it the first couple times, and I tried it on this one, too, but I couldn't get it to work

Hello, yesterday i bought my first 4x4x4 cube. 1.5 month with my 3x3x3 was fun and 3x3x3 was my first cube and it got me into cubing. So whats my probem, my problem is when i try to solve my 4x4x4 i got through reduction smoothly but when i try to solve it like 3x3x3 the problem happens with my yellow cross, it just ends up like this every time. And no F R U R' U' F' helps... I use this method for 3x3x3 (

). Is this parity error? I Googled them but it does not looks like :/. Thanks very much for your help .

Yes you have Oll parity

 

[Taker-S]

Yes you have Oll parity

Thank you very much . Solved it now...

You have what is called OLL parity. There are three new turns you need to know for the algorithm that fixes it:
Rr - Turn the right two layers up, Rr' means turn them down instead
Ll - Turn the left two layers down, Ll' is up
x - Turn the whole cube so that what was the front is now the top
Now that those are out of the way, the algorithm is: Rr U2 x Rr U2 Rr U2 Rr' U2 Ll U2 Rr' U2 Rr U2 Rr' U2 Rr'.
I hope that helped.

Thanks! I already solved it but you learnt me new moves, i was looking at that algorithm and i saw X and i was like: Whats that? And you helped me to figure it out, thanks

I can solve the centers but the instructions don’t explain the next part well. If anyone can explain better please tell me how.
Thanks

I usually refer people to the J Perm videos on youtube. He explains it in depth and very well. So go look him up.
