Anybody here do 13x13x13 cubes?

well i got 23:21.45

i am still stuck on sub-8

Does anyone know good big cube algs for the z & h perms? I've been doing my m slice algs for the 3x3. I can't execute those quickly on anything bigger than a 4x4.

H: R2 U2 R U2 R2 U2 R2 U2 R U2 R2
Z: R' U' R U' R U R U' R' U R U R2 U' R' U

There are some great ones.

Z: R U R' U R' U' R' U R U' R' U' R2 U R
H: R2 U2 R U2 R2 U2 R2 U2 R U2 R2

I knew the H perm, but I guess it's time to learn the Z perm.

Those are the ones I use for 3x3 OH and they come in handy for big cubes as well.

[...] It's hard to get used to finding all those pieces all over the place, but I like to use a trick from one of Kevin Hays' videos, where he says to put your first 4 edges onto the D layer, so that you know you don't have to look on the D layer anymore. It helps your next 4 go a lot faster, in my opinion.

I am just starting to solve big cubes and I'm so slow (barely sub 2 minutes at 4x4 and still around 5 minutes at 5x5). For 5x5 I try to do what you say about putting the 1st 4 edges on the D layer and, not only that, but I build first the 4 white edges and I put them there already in the correct place to form a cross. Is that a good idea or am I just wasting time by doing that and I should just pair the ones I see first? For me it's kind of easy to spot the edges that have white on them, as the white stickers contrast a lot.

You could try looking into Yau5 or Hoya, both utilise a cross during reduction.

I use Yau for 4x4 but currently in 5x5 I just do the 6 centers first and then just build the cross edges 1st and place them. In 4x4 I can feel the cross edges are much simpler to pair before doing the L4C but in 5x5 by using free slicing I don't think there is that much of an advantage in doing 3 cross edges before L4C but I'm a patzer so, I'm sure I must be wrong

Yau5 is a little bit different from Yau4 on a 5x5, but still fairly similar. I'd recommend just solving whichever edge you see first if you're sticking to Redux, since always going for the cross edges is going to waste some moves.

I'm very fond of Yau5. The look ahead is fantastic, especially when using a half centers type method for L4C. I never have to flip over the cube to hunt for a piece.

Makes 3x3 stage a whole lot faster, too.

I will check it out then. I'm sure there must be plenty of tutorials but if there is one that you would specifically recommend I would be glad to know.

This is pretty much the method I use on all big cubes:

Those who use Yau5, how do you solve the 3 (or 4...) cross edges? I usually put one of them on the M slice, put another one of them above that edge, then pair it up and repeat for the rest, I've been playing around with placing 3 edges in the M slice before pairing them up, but I'd like to see how faster solvers do it.

 

[EvilGnome6]

I build my cross edges on the left. No specific order and no specific ones. I put them in place in correct relative position until I have 3 of them. Then I go straight into L4C.

I was referring to how you make each individual edge...

Oh. I generally place whichever edge I'm building on the DF edge. Then I swing whatever I need into the U layer, orient if needed and move it down into the DF edge to match it up. Once that edge is complete, I swing it to the L side (in correct relative position) and repeat until I have 3 of them. Then I hold the incomplete edge on the U face while I do L4C.
