- * Note, I got Y & Z mixed up throughout the tutorial. *
This tutorial teaches you to new algorithms for the last two edges of the 5x5 & 7x7 cubes.
(After learning the ones for the 5x5, there's nothing new to learn on the 6x6. But there is some extra information you need for the 7x7.)
For an advanced method for the rest of the edges, check out Rob's tutorial:
th-cam.com/users/RobH0629#...
Here are the algorithms used:
R U Ll' U R' U' R
(Flipping Algorithm)
{Uu2 Rr2 (y z) U2} r2 {U2 (z' y') Rr2 Uu2}
(y & z are correct)
(Lll Rr) U2 Lll' U2 Rr' U2 x' U2 Rr' U2 Rr U2 Rr' U2 Rr2
[Ll' U2] [Ll' U2] x U2 Ll' U2 Lll U2 Rr' U2 Ll2
{Ll U2 Ll2 U2 Ll' U2} Ll {U2 Ll' U2 Ll2 U2 Ll}

Awesome video! 5/5 *
Good algorithms!
Question.. Your using a V-Cube 5, Right?
Thanks! You should put the "down around" sequences in some of your other tutorials!
I still love how you edit your vids with pointing in the air while recording your vid and then placing like algs on that place :D that got me laughing a few times :P
can you put up a video of how to solve the V cube 7? I cant figure out the last 2 edges on that.
I like his voice at the end when he say "have fun memorizing the algorithms! bye!"
what about the last edge where the middle edge piece is flipped?
I personally use the 7 algorithms that Nakaji uses on Cutex, they are the fastest :P (just be warned you have to be able to pick up visually because no algorithms are given :D)
will this work with the v-cube 7
@d12ckool if you do an Rr', to get the same permutation of the pieces, you would need to do an unnecessary cube rotation
The algorithm at 2:24
Isn't that like a commutator?
I think it's the same thing as doing an r move on a 3x3, where you could have been doing an L'. It's the orientation of the cube after you finish the move that determines what the move will be.
What about when u have 3 pairs of edges with one different piece in each layer
Thats may not mean the number of turns, like on a 7x7x7 the inner layers are called 2 and 3. Hope this cleared things up.
I see nothing wrong with this tutorial. There's a reason he goes fast; this is NOT for beginners. You need to learn how to solve the cubes normally before learning these complicated algorithms. Either that, or all you guys complaining have really short attention spans.
ok im confused and don't know what to do,im working on my 7x7, i watched all of the situations you showed, and i don't know what to do. so looking at them on the top (they are green/ orange and blue/ yellow pieces) and left to right i see top edge - blue green yellow blue blue, then the bottom edge is green green green blue green. please someone help cause im stumped :\
woohoo you finally do U' and R' instead of Ui and Ri! yeaa
this is grreatt!
i think the only problem I have is with my 7x7. I just got it for Christmas, and I'm confused with the last 2 edges. I can't seem to find the algorithm(s) to solve the last 2.
Thanks
@MeMyselfAndPi Can you do just the parities for the 7x7 and slowly go through them? Like repeat steps and not using your fingers to spin it, twisting your hands just so it slows down and lets people who aren't speed solvers (such as myself) can actually see what to do. Just slow down about 10 times bud.
And there's another parity you missed. The two middle corners (second layer in from outside) flipped upside down.
Plus, the algorithms don't make much sense. Try L1 (first layer in after L)
You would have to do an r, but you would have had to do an x' as well to get the same affect as the triple l.
I think it's time to update this notation. WCA standard works really well for big cubes.
@farmvilleisawesome : it's available on v-cube website ... order online !
For the first one, couldn't u have done a R2, Uu2, Bb2, used the flipping algorithm then Uu2 and Bb2? It's easier to memorize and for me it's faster.
....why do a triple l when u can do an r'??
@MrCross0530 along with L2 (second layer in from L) and L3 (which would be the immobile center lines) And use it with the other faces too. That's a lot more easier to understand. X, Y, Z axis are pretty simple, so is the Prime, but Lll' makes no sense whatsoever.
Just adjust them a little, make them better sense.
And slow down.
you have to watch his v-cube 7 breif tutorial and try to pay very close attention
helpful.
And you don't need to use the whole flipping algorithm unless you're worrying about the cross or supersolving. You could use 3 moves instead of 7
NOO!!! IT CAN'T BE!!! HOW COULD I HAVE DONE THAT!?!? ARG!!!!
Well, thanks for telling me, I'll just put in an annotation saying that...
for those struggling with the 8:00 algorithm to swap two edge pieces. This is closer to SSE notation to do this. Note that where I've used L or R, he is using N3L and N3R, (3rd layer in from the left and right) this also works for N2L. Since we're operating on only 2 columns here, I've just used L and R which while technically incorrect, is easier to read for beginners.
L' U2 L' U2 F2 L' F2 R U2 R' U2 L2
what happens when only one of the middle edge pieces are flipped the wrong way when solving the last two edges :P
To make the U center in F. 3L is faster than Rr' x'
y and z are wrong. y is rotate to the right and z is rotate the cube clockwise like the front face.
@MatthewAustinQuasel Actually, nvm. I was thinking of a different one.
that means that it's not the middle that's flipped the wrong way, it's the 4 pieces either side.
Or not, you beat me by 3 seconds!
HIT THE BRAKES
dude the flipping algorithm is scrambling the cute (both centers and solved edges)
i made sure im doing it right. what the hell is this?
the edge flip doesn't work
YOU REALLY NEED TO SLOW DOWN THOSE MOVES MADE ME GO BACK TO THE CENTERS
More in depth:
()= Perentheses
[]= Brackets
{}= Braces
because the centers will stay the same if you do r'
No, to flip the whole edge, it's that algorithm, for any cube, excusing the 2x2x2
for the love of god man, when you just need to flip 1 edge without having to worry about anything else i.e when all the centers are fine, you DO not have to use the flip algorithm. (with the piece that has to be flipped on your right hand with the pieces it has to match on the left. do a R F' U . and the right edge is flipped
Damn! This is way too confusing! I guess I just need some more practice to be able to do that!
+XReviewer - XGamer Thanks! I would've never noticed if you didn't point that out.
omg how hard is it to get X Y and Z correct?! EVERYONE messes it up. god it complicates things
for the edge flip, why not just do R F' U F?
@d12ckool its not the same
WHAT IF ONLY 1 EDGE IN THE MIDDLE IS FLIPPED
WTF DO I DO
Just In case you don't know yet. It is a parity. The alg is Ri U2 L F2 Li R2 U2 R U2 Ri2 F2 U2. Treat the right column of the center as the Rs and Ris, and the left column of the center as the Ls and Lis
No, really? After the annotation AND Video Description?
Subliminal cube rotation.
acually that algorithm requires a cube rotation, and its takes time to do 2 F moves
i know. i'm just saying it's hard to memorize an alg when someone screws up the notation
"Pointy brackets" are really called "Braces".
that alg doesn't work because if the centers were sliced they wouldn't be parallel to each other
actually, I think I know why he does them so fast...that way he gets more views from all of us noobs watching it 20 times to figure out what he is doing.
learn to read it says advaced
E=MC^2
02:16 very simple algrothm....
The algorithm written is confusing to me because of rolling the whole cube back and forward. Try this without rolling:
L' U2 L' U2 F2 L' F2 R U2 R' U2 L2
Are you five!?!?!?!
they r advenced
X, Y, and C rotation?... its Z (Zed) and not C
besides, if someone tries to solve the 5x5 there is no new notation to teach.
I WAS 10th RATE!
6000th view!
you mixed up y and z
@jovanholden1 haha, i see this comment in every of his vids.
you messed up on the notations on y and z
+HBSlyrics He wrote that in the discription
+Gurkan_Skywalker sorry didn't see that in the description
Um... you're notation is wrong... in more ways than mixing up z and y.
I watched up to 07:12 of this video. Then I saw "(Advanced)" in the video title.
I can't do this.
Slow the eff down!!!!!
Trying to keep up screwed me up and messed up all the edges. >.
you really need to slow down, impossible to keep up with
Ste Hobin i
Not fast enough...
First!
Why can you go slower? Is it really that hard to go slower? Im not haring, but this is very stressful and annoying the way that people teach.
u go 2 fast
I'm 6,666 who see this TUT :( :( :(
I have a better flipping algo. R,Fi,U,F
Way to complicated
This made absolutely no sense
ok, first you should avoid cube rotation because you algorithms gets longer and it' not good for speedcubing, if you are interupted in this algorithms you are f*cked
ur algo is so confusing
just watch cutex cuber algo..it is better.
SLOW THE F DOWN WHEN YOU DEMONSTRATE.
Cancer
This video was no help to me because you went wayyy too fast.
Video is a bad tutorial.
real bad explained. thumbs down
The Terrific 2 it says "BAD"
