How to Solve a 2x2x2 Rubik's Cube - Easiest Tutorial in HD. 2 Easy Algorithms to Memorize

Do .

Hello youtube , Ethan D here today .

I have uh a kind of a follow up tutorial on how to solve the mirror blocks or the mirror cube .

Um So uh on my last tutorial , uh someone uh suggested that I do another tutorial just on the last layer um because it was slightly confusing , I would admit .

Um So this is gonna be that tutorial and uh I'm going to be solving the top layer as the thinnest because in that tutorial , I mentioned that it's easiest to solve first layer as the biggest cubes because they're the easiest to find .

So that would mean the thinnest layer is going to be our last layer .

So that's the one we're gonna be starting on .

OK .

And I'm gonna take you step by step just like if you're a beginner .

Um And then once you do the two by two the three by three is gonna be really super easy and you can check out my other video on the three by three and how to do it .

And I also have a video on how to um get through the second algorithm which gives you a lot of different um patterns .

And it's a really good video just for that specific algorithm .

So check those videos out uh when you're ready to do the three by three .

If you've already done the three by three video , then this is gonna be really uh easy , but just bear with me on the beginner stuff .

OK ?

So here we go .

So a two by two has no center .

The one thing you do have to remember are the colors .

Um Let me , let me kind of explain on a regular Rubik's cube .

If you see the red , the opposite of red is always orange .

Um the opposite of white is always yellow and the opposite of green is always blue .

So uh let's go ahead and scramble the last layer .

OK .

Here we go .

Here's the scrambled top layer .

And once again , we're gonna be using the top layer because the bottom layer is the easiest to start off with .

OK .

So if you know how to solve a three by three , which you should know before attempting to solve the mere locks , you know , the first step is to solve the cross .

So we want to get all four of these edge pieces on the same plane as the center as right now .

It looks like their walls and they're towering over the centerpiece .

That's not what we want .

So this is gonna be the hardest case .

It's gonna , it's gonna look like this on a three by three where none of the edge pieces are flipped the correct way and you can see whites are here .

So what we want to do next is the uh the uh algorithm that flips these pieces which is front , right tap right , inverted , top , inverted , converted .

So that's gonna give us this kind of L shape .

So on a three by three that would look like this front , right top , right , inverted , top , inverted , front , inverted .

So that will give us this L if you can see this L compared to this L .

OK .

So next , what you wanna do is you want to hold the L with looking at it from the top down , top down , uh One's on your left and one's on the top .

So it's gonna , it's gonna look like this front , right , top , right , inverted , top , inverted ed .

Let's go like that .

OK .

So now you have this horizontal bar on the three right there , it's gonna look like this front , right top , right , inverted , top , inverted , front , inverted .

And then now we have this horizontal bar .

You don't want to hold it vertical for this next step .

You wanna hold it horizontal .

You wanna do it one last time .

Front , right , top , right , inverted , top , inverted and front , inverted .

So on a three by three , that's gonna look like this front , right , top , right , inverted , top , inverted , front , inverted .

So now as you can see , we have lacrosse .

OK .

Rur Prime Uru two .

Our , so there we go .

Now all of them are matched up .

But there's another case and I'm gonna show you it on the three by three .

It's where these two are across from each other that are matched up .

This one's matched up , this one's matched up , but these two are not .

So what we're gonna wanna do is just the same algorithm rur prime Uru two R prime .

And that's gonna give us two adjacent ones that are matched up .

So these two are not , these two are next .

What we want to do is we want to turn the top layer once either direction it does not matter .

And then one of them is going to be matched up .

And as you can see , none of the other ones are matched up .

So I'm going to do it one more time , Rur prime Uru two R prime .

We're never gonna do L .

So don't worry about L .

You'll see some algorithms on youtube that where they do L you're not gonna need L OK in this video .

Um So we're doing R and clockwise is regular R , counter clockwise is prime .

OK .

So um this , this is a good way to memorize the algorithm .

Are you our prime ?

It's like a question like someone is asking someone a question .

Are you our prime ?

And then the person rep replies you , are you two times our prime .

All right .

So here we go .

Are you our prime , Uru ?

Two times ?

So you turn it over two times R prime , which is clock uh counterclockwise .

All right .

So , but this is when you're already done with another step , the other step is gonna look like this .

So on the mirror blocks , I'm gonna get that step .

It's gonna look something like not that because that one also has a crack piece .

It's gonna look something .

Well , this is where you have to orientate all of them .

Uh But no , sorry , this is correct where none of these are in the right place .

These two need to be switched .

These two need to be switched .

So it's gonna look like this as on here , none of them are in the correct place .

As you can see , uh these two need to switch and these two need to switch .

Um but that's this case and then you're just going to do it from any random position .

So I'm gonna show you the algorithm on the mere blocks first .

So if you have this case where none of them are in the correct place , you go , you R , you prime L prime , you our prime U prime .

Oh So now as you can see one of them is in the correct position .

So on a three by three , it's gonna look like this .

You R U prime L prime , you our prime U prime .

Oh So now as you can see this one is in the correct position , but none of the rest of these are .

So next step , we're gonna put that correctly placed .

Piece in the bottom right hand corner .

If you look at it from the top down right here , I put it here .

Do it one more time .

R , I mean , sorry , Uru prime , L prime , Ur prime , you prime and L prime .

So , NL I'm sorry that last one is now .

So we got lucky and then all of these are already in the correct , already oriented correctly .

So if you're going on a three by three , I'm gonna show you that algorithm you RQ prime L prime U lrr prime , my bad U prime .

Oh So now as you can see , all of them are in the correct position , these two are not oriented correctly , but that's gonna be our last step .

So on the mere blocks , I'm going to quickly cut away and show you the last case .

OK .

Here we go .

As you can see , none of them are in the correct position .

All of them are in the correct position but not , but not permuted correctly .

So same as here , except these two are already permuted .

These two are not , this is going to be your hardest case .

This is going to be an easier case .

I'm going to show you the algorithm on here first and then on here .

So what you want to do our prime D prime R D and that's the algorithm , but you're going to have to repeat that many , many times .

So as you can see , we replaced the corner and we want to get it back .

So I'm gonna do it one more time , R prime D prime R D .

So now , as you can see this corner is permuted correctly , it , there , there is a possibility where you , you're gonna have to permute that corner one more time using that algorithm twice again .

But for now that one's correct .

The algorithm two more times R prime D prime R D R prime D prime RD .

And there is the algorithm two more times .

And as you can see , we permuted it , we permuted it .

So the most you're gonna have to do that algorithm for one corner is four times .

But it's a really short algorithm .

There's only four moves .

So it's not that hard .

So let's turn the top play one more time .

Also if you're wondering , you're messing it all up .

It's going to fix itself after you fix all the corners .

So one more time , R prime D prime RD , R prime D prime R D .

So once again , this corner is still not permuted even though we did it twice .

So let's do it two more times .

R prime D prime RD , R prime D prime RD .

As you can see , it's almost solved , just turn the top layer or however many times you need .

And there you go , you're done .

But I'm going to show you that on the three by three just to clear , clear up any confusion .

So it's going to be R prime D prime RDR prime D prime RD .

As you can see this corner is permuted correctly , but it's all screwed up .

So let's move on to the next one you don't need to do to this one because it's already correct .

Let's move on to the next one .

R prime D prime RDR prime D prime RD .

This one is still not permuted .

So let's do it two more times R prime D prime RDR prime D prime RD .

So as you can see now , all we need to do is turn the top layer twice .

So there we go .

That is how you solve the mirror blocks .

Uh I hope you guys found this easier to understand if not uh leave your comments down below and I try my best to answer them .

Um And then also if it's not good , I might make another clarification video because the mirror box is can get very confusing .

Uh but you have to look at the shapes and not the stickers colors .

So I hope you enjoy this video and until next time , goodbye .

And now we'll go ahead and finish the cube as you can see , we only have these two that are in the opposite spaces .

Everything else is solved and we do the R prime fr prime my back two times RF prime R prime back two times R two times and U prime uh this cube is stuck .

So what happens when you get a cube for five bucks from China ?

It's a little sticky but it's kind of cool cube .

Um So that's it guys .

I hope that answers all your questions , please .

Uh Give me thumbs up likes and um let me know if you have any questions I try to answer as much as I can .

I am gonna be doing a four by four tutorial soon .

Um This one has a parody right now and we'll explain that in the four by four and enjoy guys .

Talk to you soon .
