One-Answer Big Cubes Question Thread

[Drad]

I'm sure you can search for a good video, but basically you just need to be a little creative with slicing, flipping, and slicing back. You can flip the FR edge with R U R' F R' F' R.

i can't seem to find a good tutorial if you could send me the link to the one you used it would be much appreciated

Just do the OLL parity for 4x4 but only move the innermost slices and not the outer 2 layers.

Thanks! I was thinking it was something like that, but I tried it a couple of times and I think I messed it up somehow. My OLL parity alg also requires U2 Rw' Lw (U2) on the end to finish it off, but it works now. I've got a 6x6 pb of 9:29. It will be a while before I start blowing the competition out of the water.

Are there any good tutorials or tricks for advanced 6x6 centers? I'm generally making 1x4 blocks and inserting them, center rows first, then outer rows, unless I have an obvious 2x4 block that I can make. I'm running ~9:00, and it feels like centers are the worst part. I'm using Yau, more or less as I learned it for 4x4, so I solve 3 edges before I do the last four centers and solve the 4th cross edge next once I'm done with centers. On a good solve I might insert that 4th cross edge by 4:30 or so, and end up around 8:30.

Whats the optimal splits for 5x5, 6x6 and 7x7 using reduction?

Whats the optimal splits for 5x5, 6x6 and 7x7 using reduction?

If I had to guess my first thought would be to base it in pieces to place at each step, making the optimal splits:
5: 48/36/20 or 46.15/34.62/19.23%
6: 96/48/20 or 58.54/29.27/12.20%
7: 144/60/20 or 64.29/26.79/8.93%

You could also calculate it on optimal move count, but I have no idea where to start on that. Stickers to place would be another metric, that would take into account the extra difficulty of lookahead and maintaining the centers while edge pairing. That would result in splits of:
5: 48/72/48 or 28.57/42.86/28.57%
6: 96/96/48 or 40/40/20%
7: 144/120/48 or 46.15/38.46/15.38%

Not sure if that's the answer you were looking for, but at least it's an interesting answer to calculate.

that is exactly what I was looking for, thanks!

How should I set up my Yuxin 5x5?

 

[Travis_]

A couple weeks ago I was solving my 5x5 and I encountered this situation. I have scrambled and re-solved it numerous times, the only thing that changes is sometimes you will get the incorrect edge sets on adjacent sides and sometimes they will be on opposite sides. I can not find any information on how to solve this, I am familiar with this parity on the 4x4, but I'm not even certain this is supposed to happen on the 5x5. I have not disassembled my cube and it was fine before... Any help would be much appreciated.

Assuming the three edges in the back belong where the three edges in the front are and everything else is solved, this is an impossible case, and you need to disassemble the cube. If the right edges are also unsolved, you have a U-perm.

Also, this is my 1,000th post!

You could just cycle four center caps around the cube. No disassembly necessary.

What is the best 5x5x5 Method?

 

[SolveThatCube]

Yau5 and Freeslice are the top 2. There have been a few debates over which one is better but they both have there benefits.
Yau5 is probably more efficient overall. (i.e. no z2 rotations during edge pairing)
So if you're having trouble deciding which one to learn then maybe just go with Yau5.

 

[Rubix Cubix]

You could also try using Hoya for 5x5, not as widely used but still a good method and it's what I use. You can still get good times with as well.

Sorry I forgot about Hoya. It's worth a look at.

 

[One Wheel]

I personally like Yau, but I don't do the 4th cross edge before l4c: too easy to mess it up during l4c, so I do the 4th cross edge after l4c and before the rest of edge pairing. Hoya it's too much of a hassle to orient the edge pieces while forming the edge with only 2 faces to work with. I've played with it, and it slowed me down 40 seconds to 1 minute (~25%). I used to use Yau on 6x6 and 7x7, but switched to redux after watching Kevin Hayes' video on the subject.

Loosen it. My friend did not want to but he did and it is good.

I broke a piece on my QiYi WuJi and it's going to cost me a f***ing fortune to get a replacement from TheCubicle.

Does anyone know of any other cube store that sells replacement parts?

Spoiler

I've already contacted SCS but I doubt it's going to be much cheaper.

 

[Gold Cuber]

speedcubeshop has it at at 75 cents a piece usually

Turns out I was wrong - it is a LOT cheaper than thecubicle.
