How to solve a Rubik's Cube (Second Layer Tutorial) _ Part 3

May the cube lead you to the cross .

Um The video is finally here .

You guys wanted to learn how to do the four by four .

And I I am finally filming this here .

It is um you , this is the easiest way to learn how to do the four by four .

There's only six algorithms to learn super easy .

If you've already seen the two by two , you learned two of the algorithms already .

OK .

That's if you've done this one , I've done a video on this , check it out .

Um If you see in my three by three video , you've learned an additional two algorithms , you can do this with only four algorithms .

And by the way , algorithms are not a big deal very easy to learn .

Uh they're just patterns and this one , you're gonna need to learn an extra two .

OK .

Um There the one thing about the four by four that you need to know is there's no center .

And then , so this is the bad one because the middle one isn't oriented properly .

And also in the middle , you , you don't want any yellow pieces because when you complete it in the middle and what is on the bottom in the middle , there aren't any um yellow and also in the middle , they should all be matching .

This is good because or this is orange and orange , orange , orange , that's matching green , green , green , that's matching red , red , red , that's matching blue , blue blue that's matching and this one , no , no , no , no , no , no , no , no , no and so on .

So um yeah , I'll be right back to I'll scramble , I'll scramble my tube and I'll be right back to explain it in more detail .

OK ?

So um I scrambled it and then I finished the doing the first layer .

So and then , so that now put the white um side on the bottom .

And then , so now to finish um to do well , actually , this is the first like episode that you start learning um algorithms .

And if you don't know what an algorithm is , it's basically like a sequence of moves that does one thing .

So when we do algorithms , we use letters .

So this would be an F this would be a um F counter clock or counter .

Yeah , I don't know .

And then this will be you and this is I just call it prime .

So this is U prime , this is R , this is our prime , this is L and this is L prime .

OK .

Now , so let's get to it .

So this one you have and when you're choosing an edge , make sure it's always on the top layer .

So on the yellow side and then this make sure it's always in the edge and make sure it's an edge without a yellow um color in any of the side .

So this one's good .

This one's good .

This one's good , but this one's not because there's a yellow on either one of them .

So they just choose this one .

So first you have to match it with the color that's facing you .

So now it's matching and you have to think about this .

So this is the green .

Do you want to make the green go on this side or do you want to make the green go on this side ?

Well , make the green go on this side because you can tell that this is the green side , but this isn't .

So to do this , it's basic , it's really easy , you face it away .

So you , and then you make it go up or U prime and R prime , then um I'll have the algorithm right here .

So then you just put it back in normally .

So you turn it upside down again and then to put this in , you just do it like a normal um pair .

So you do , you move it out of the way you put it down , you put it in , you put it back in .

OK ?

Then um then please keep in mind that this isn't the fastest way to do it , but it is probably the easiest way to do it .

Now .

Um we can't do this one because blue and yellow and we don't want any yellows .

Also , we can't do this because it's orange and yellow .

There's a yellow .

Can we do this ?

Yes , because this is blue and red .

There aren't any um yellows .

So you have to align these two .

So you have to create the center very similar to the two by two where you have to make sure that the colors are on the same size , like the red , opposite of red is orange , opposite of red is orange .

Um If you mess it up on the four by four and you put uh blue next to red .

Uh It , it won't work out .

So um we do start with the centers .

All right .

So guys , we're gonna get right into it and basically it's gonna be just like doing a three by three once we get through phase two .

So let's go ahead and mix this up and we'll mix it up real good .

And this is the easiest four by four video , most four by four videos that you're gonna see out there are giving you all kinds of complex algorithms and um just crazy amounts of algorithms to learn .

Uh If you've already done the three by three , this is gonna be fairly easy .

You just need to learn a couple of little things that are uh gonna be different than what we've learned already on the three by three and the two by two .

So this is pretty well mixed up .

And now what you want to do is you want to create the centers as you can see .

Uh there are no centers .

So we need to create it .

So we're gonna start with , I always like to start with yellow and white since we've worked with yellow and white in the previous videos .

Let's go ahead and try to do the white .

So as you can see , I've got two whites here , I just need to find the other whites and that's pretty easy right there .

I've got three for the corner .

So we're gonna do the centers , there's the other white and the way you do this is if you , I wanna bring this white over here , I'm going to line it up with two .

So make sure you've got two whites and we're gonna bring this white over here .

So you always want , wanna have two .

So as soon as I bring this over and it needs to match up with this , all I do is turn this like this and bring it back and there you go .

That's the first one .

Now what's opposite of white is yellow .

So we're gonna go to the other side .

Luckily we've already got two yellows there .

Um Now we're gonna go ahead and find two more yellows .

So I've got a yellow right here .

I need to bring that over .

So I'm gonna line up the yellows so they line up with this yellow , I'll bring it up like that .

Turn get it out of the way and bring the yellows back .

See .

So we're getting the centers ready and as you can see , it doesn't mess up the back .

Ok .

It doesn't mess up your other um , centers that we already did .

Ok , let's find the other yellow there it is .

So what do we do ?

We line it up with two so it's lined up here .

Um , now this one doesn't line up , see .

So that's not gonna work .

So line it up with another two .

So we'll turn this around like this .

We're gonna line it up with these two .

See , now when I turn it , it lines up , once it's lined up , turn the , turn the top and bring it back .

Now we've got yellow and we've got white .

Now keep doing this .

Um , if you don't get it at this point , just continue watching because we're gonna do the same thing with another color .

Here's where it gets tricky though .

We need to know where are we going to do the next color ?

I always like to take the yellow and put it on top whites on the bottom and make this blue .

OK ?

Um And it can be in any of these .

So I'm gonna find a side that has the most blues , they all have one .

So it's fine .

We'll just make this uh face that I'm working with blue and then to the right , it's gonna be red .

You , you just bring it to the with um you wanna bring this , you wanna replace this one with this , so you just do the same thing , Uru prime R prime and then you just put it in normally , then the piece that you , that was in it gets out which because you replaced it and then now you can put it in normally .

So since the blue goes that way you do Uru Prime R prime , then it ha it makes like a pair and then again , you just put it in normally .

So um yeah , that's how you do the second late er of the three by three , Rubik's Cube .
