In this video I'm going to show you how to solve a 5x5 Rubik's Cube
Check out my other videos showing you how to solve a 2x2 Rubik's Cube, a 3x3, a 4x4 and even a 5x5
As explained in the 4x4 video, when using algorithms with a 4x4 or a 5x5 I just need to explain a little addition
We still use F, B, L, R etc for front, back, left, right
But when it's the outer face is a capital letter
So if I said R, that would be R
But if we have a lowercase letter that would be the inner face of that letter
So that would be small r
If the algorithm tells us to turn both, that would be a capital R and a small r in brackets
And it's the same if you want to turn inverse or anti-clockwise
That would be capital R inverse
This would be lowercase r inverse
If we had capital R and lowercase r in brackets together inverse, with an i after it, that would be that
And if you want to turn them twice, a 180 degree turn
It would be R2
Or if it was the inner face, it would be a small r2
Which would be this
And if it was both, it would be capital R and small r in brackets 2
And when I'm doing the small r you see me do that, I turn both and turn the outer one back
Just because it can be quite difficult just to push the one on its own
That time it worked but if it's not lined up perfectly it's really difficult
So when you see a small r it's actually that
But what I'm doing, just to make it easier I'm doing that
But that is a small r
Small r
And it's the same for all the other letters
Same with L, same with F, same with B, U, D etc
Ok, now we have the Rubik's Cube in this position we basically just have a scrambled 3x3
And you just complete this Rubik's cube exactly the same you would a 3x3
And you'll be pleased to know from now on, when you've got every edge completed
There are no other parity errors that you can run into
This is now exactly the same as a 3x3 and you complete it as a 3x3
So sometimes you don't get where all these match up
Sometimes you do get another parity error
Sometimes you will get this
Sometimes you will run into this parity error where you have got one two three four
five six seven eight nine ten complete
But you're left with two incomplete
This is like a very similar parity error that you get on the 4x4 where you're just left with two
When you've got just three left
When you correct one pair they all fall into place like it just did for me
But sometimes you don't get three left over, you get two left over like this
Sometimes the three will fall into place, sometimes it will leave you with two
When you've just got two there's no way you can get out of it
See you bring that one together, well you've got three, three, three, three so you can't bring any of those down
The same with here
And on the back you can't even bring one of these to the top to use either because they're three
So every time you match this one, you put it to the top, you bring another one down, you'd break another one
You're stuck in an infinite loop because you've only got two left
It's called a parity error
You're stuck in an infinite loop
If you're stuck in this parity error, you need to put them in a certain position
You need to put them in the position they're in now
So when you turn them they line up like that
So the pair's are both at the bottom and the singles are both at the top
You don't want the single at the bottom, pair at the top
and the other side, a pair at the bottom, single at the top
Like this..
See how I have the pair at the bottom, single at the top
This side I have a single at the bottom, pair at the top
You don't want it like this
You need to alter your cube
So you have both pairs at the bottom, both singles at the top
Once you've got them in this position you need to turn this front face to the top
and turn it to the right
So you've got the singles in what would be the lower case r or the small r
Remember this is the large R, this one inside is the small r
Basically in here
And the two pairs on the left-hand side
So the singles to the right of the center and the pair to the left
When you got in this position you need to perform this algorithm
Which is
(Ll)i U2 (Ll)i U2 F2 (Ll)i F2 (Rr) U2 (Rr)i U2 (Ll)2
So let's do that
So it's
(Ll)i
U2
(Ll)i
U2
F2
(Ll)i
F2
(Rr)
U2
(Rr)i
U2
(Ll)2
And that has corrected the parity error of these two edges
So as I said, once you've got all the centerpieces completed
and then you've matched all the edge pieces into threes
You've now got a scrambled 3x3 basically
and you just complete this exactly the same you would a 3x3
You'd start by making your cross
Then you'd do the corners
Once you've complete the green face then we do what would be stage 3 on the 3x3 Rubik's Cube
Then we would make the cross using stage 4 of the 3x3
This will be the FRU RUF algorithm
Again, I'm not really explaining how to do a 3x3
You should already know solve a 3x3 if you're doing a 5x5
If not, go check my 3x3 tutorial out
Then you position one, and you do the algorithm for positioning these edge pieces
This would be stage 5
The next step is the corners
You find one that's in position and then do the algorithm with that one in the top right
This would be stage 6 on the 3x3
And then once you've got all the corners in position it's just rotating the corners into position
Using stage 7 of the 3x3
This is the Ri Di R D algorithm
Exactly the same as a 3x3
And there we have a solved 5x5
Hope it helped guys and thanks for watching
