Put the flipped edge at the front, and do the following alg:

Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw U2 Rw' U2 Rw'

You'll then have a normal 3x3 OLL.

EDIT: You can actually put the edge anywhere and it'll still work. But if you're using 2LOLL, you'll skip the first look if you put it at the front

Thanks all, I will keep working on it.... Not sure why I am having such difficulty with this lol.. Great forum, thanks for not flaming me about such a newbie question

 

[Sa967St]

There a bunch of common algorithms you can use to flip the dedge. If you don't like the ones already mentioned, you can try out the ones here:

[KCuber]

you also might run into pll parity the alg for that is:
r2 U2 r2 Uw2 r2 U2 Uw2

We're all new at some point Good luck with 4x4!

That looks like a sune OLL with an edge parity, put the upside down edge to the back and try:

Rw2 B2 U2 Lw U2 Rw' U2 Rw U2 F2 Rw F2 Lw' B2 Rw2

followed by:

R U R' U R U2 R' (sune)

hope this helps.

If you put the bad edge in back, doing that parity alg will result in having two flipped edges, so a Sune will definitely not solve OLL.

This particular OLL case would be solved like this: Put the bad edge in front. Do L F' L' F, followed by that parity alg in the above quote, followed by L' U L.

But OP shouldn't be worrying about 1-look parityOLL, so I'm not sure why I just posted this...

@OP, here's a brief explanation of what you need to know. On a 3x3, it is not possible to have an odd number of edges misoriented. Every single OLL case will always have an even number of misoriented edges. On bigcubes, due to the fact that each "edge" is made up of more than one piece, funny things can happen. At this point, you shouldn't bother trying to understand why, just understand this: On the 4x4, it is possible to get to the last layer and have an odd number of edges misoriented (as in the picture you posted). You must memorize a special "parity" algorithm to deal with this. All the algorithms people have posted in this thread are examples of such. Experiment with different ones and see which one you like the feel of the most, and memorize it. Whenever you get a last layer with an odd number of edges misoriented, use that algorithm. Most common algorithms will flip the edge on the F face, so it is best to turn the U layer to put one of the misoriented edges on F before executing the algorithm, in order to have an easier OLL (especially since you use 2-look OLL, you can "skip" the usual first look this way sometimes)

4x4 OLL/PLL recognition?

I'm finding it difficult to recognize them while doing my 4x4. I'm guessing this will come with practice just like my 3x3 but was just wondering if anyone has any tips? I'm learning Yau so it might just be my brain melting down lmao

OLL, count the edges. If it's even the breathe a sigh of relief. Recognising PLL parity is a bit more tricky but it comes with practise. As a rule of thumb if it looks weird, get slicing. It only takes 2 seconds to Rw2, U2, Rw2, u2, Rw2, u2, U2 after all and you'll likely waste that time staring dumbly at the pattern that's not quite an R perm but sure looks like one.

 

[Pokerizer]

PLL are not do bad I really think its the OLLs that are kickin my butt. I'm sure that the more I solve the faster it'll come.

Help with Sub-1 on 4x4?!?!

Hey Guys.

So I recently switched to the yau method for the 4x4 and my times dropped like 2 seconds in every average of 12. Within a few averages, Went from sub 1:30 to sub 1:20 and then sub 1:15 and am slowly getting consisten sub 1:10 times. But now ive just hit a block. Here is my time breakdown

3-6 seconds:first two centers

10-14 seconds:first three edges
10-15 seconds: rest of centers
15-20 seconds: rest of edges
20-25 seconds: 3x3 (depending on what parities i have)

I average 17 sec on 3x3 and 1:13 on 4x4.

What are the next general steps i have to take to get sub 1? my PB is merely 59.19 seconds.

 

[leonparfitt]

when this happend to me i started to practice 3x3, by doing this i found that my 3x3 stage got faster and it improved my TPS so very stage got a little bit faster. After you do this the only thing you can do really is practice. Id just like to add that just because it help me average sub1 it might not work for everyone.

hope it helps

 

[JianhanC]

I don't use Yau, but I think the remaining of the edges can be faster. Just turn faster or slow down enough for lookahead for the entire solve.

 

[WBCube]

The first 2 edges can be improved substantially, I think. Know where the edges are for the most part during your building of the first 2 centers. Also, if you aren't fully CN I'd recommend that to you.

Sub-2:30 4x4 help

I am very slow at 4x4. My best is 2:28 but I average closer to 3 minutes. I use yau method and a lanlan 4x4. Do you have any tips for this puzzle? I average about 33 seconds on 3x3 if that helps.
Please do not ask me to search because I did already and couldn't find anything.

 

[SirWaffle]

I'm not that fast on the 4x4 either but I do have a few tips. Slow down(obvious one) Slow down in your edge pairing and always be looking for the next piece you need. This really helped me alot. Find an edge pairing method you are comfortable with. You might not want to use Yau yet until you get a better understanding of the cube. Also Yau makes the last 4 centers difficult if you are new to big cubes. Use inspection time wisely. Plan out your first two centers. And something I did to help with this is to solve them blindfolded like you do for the cross on a 3x3. Hope this helps a bit

 

[pjk]

Make the best of every situation. Don't just solve a pair of edges one way because it is the way you know, but instead find the best way to solve them. What method are you using and what is your breakdown of each step roughly? That would help us determine where you can improve the most.

 

[TheNextFeliks]

I think I will switch back to reduction for now. A breakdown with reduction is :30 centers, 1:30 edges and :45 for 3x3 (more if parities. I use 3-2-2-2-3 for edges.

 

[ben1996123]

your edges are slow
