About This Class

             Hello. In this class I will be covering every detail required to solve the 4x4 Rubik's cube; also known as the Rubik's Revenge. The prerequisite for this course is that you must know how to solve the standard 3x3 Rubik's cube in any fashion you see fit. The 4x4 is a small challenge for those interested in solving it and I feel it is a step in the right direction if you would like to be introduced to the world of "big cubes". More lessons to come so please follow me for future content. Good Luck and Happy Solving!

1. Introduction: welcome my course on how to solve the four by four. My name is Byron. I have been a competitive speed solver for about the last 11 years or so, and within that time I've taught well over 300 people you both online and in person, how to solve various types of cubes and twisty puzzles. Now this course is going to directed at those that want to learn how to solve the four by four. But you already have at least a base knowledge on how to solve a regular three by three Rubik's Cube. As long as you have that checked out, then this is gonna be, ah, pretty fun puzzle for you, Honestly, out of everything that we have on the table, This is probably one of my most fun and most entertaining puzzles. For me, it's a little bit more challenging than the regular three by three, but it's by no means extremely difficult. So as long as you at least know how to solve three by three, this is gonna be a lot of fun. So with that being said, let's get started 2. Basics of the 4x4: All right, you guys, before we get started with the four by four, just wanted that. You guys know if you're interested in picking up a quality four by four like this one or any of these cubes I have in the background, anything that you guys are interested in, even this Matt, I'll have links in the description so you guys can pick some of the stuff up for yourself. So the first thing you guys are gonna want to understand about the four by four is the structure you're gonna want. Toe. I understand exactly how this thing ticks. So we want to compare this to a three by three. So this is my gang three by three. And if you look at it, the centerpiece has four pieces versus a three by three. It only has one because of this, the centers Comtech, Nikolay move around on a four by four. That could be split up. So the first thing we're gonna be doing is we're gonna be assembling those centers. And then if you notice the edges on a three by three, it's one piece. But on the four by four, the edges consist of two pieces, which can also be split. So it's gonna be another thing we're gonna have to do. We're basically gonna be making this into a three by three. So that way it can be solved like a three by three. So we're gonna start with centers and then we're gonna work on to the edges. There is something called parody, and we're gonna get to that later on. But I think you guys gonna have a blast. You guys have fun time with this, So we're gonna touch on Cuba notation for a little bit. Que notation will basically tell you exactly how you are going to move the cue based on written instructions. So, for instance, same thing as the three by three. This is gonna be our This is gonna be our prime. This is you, you prime f f price. Although it's all the same. However, because you have these other layers right here, there is going to be some different notation. So if you want to move to of the layers like this, you're going to do the notation r w and I'll be posting it around here somewhere. And then if you want to move just that middle layer right there is gonna be no be denoted with a lower case letter of the side you're turning. For instance, this would be a lower case. Far. This would be a lower case you and this is gonna be a r w you w So that's basically how that Cuba notation is going to work. You won't have to deal with this too much in this tutorial. There's for the most part, there's not really any algorithms here, but just is just so you know, for future reference how to read to those algorithms I'm going to show you. 3. Centers: So now we have the cube scrambled. First thing you're gonna want to do is start making centers. You're gonna find the four pieces in the middle that are the same color, and then you're going to solve them. So here first thing I would look for is a bar that's already solved like this one. Or like that one you can pick any color that you want. I'm going to start with the green and we have these two already done. We just need to find the other two. And those two can be mixed throughout the Cube. There's one there, and there's one here. So once you find the two that need to be paired, all you have to do is set them up in a way that you compare them without messing up the one that's already there. Then you're just going to step it aside like this and then just move it up and then you have your first side. Sometimes you may not be able to find any bars like that, so I'll give you an example. I'm going to start on the opposite side, so I'm gonna give you an example on another bar So, for instance, opposite green is going to be blue. So I'm gonna make blue right here. So I'm gonna see I have this one right here. Now, I could pair this one and this one up. I could do it like this, and then I could move this bar up to the top like this. That's one way to go about it. Now I have this one and this one, so I'm going to pair those two up is, well, same thing. Now, when you have a bar here in a bar there, you may have the inclination to set them apart and go like this. But when you do that, you are going to break up that green side that we already solved. Now you're like, Okay, how do I get this up here? Because it's not. It's not moving anywhere. How do I do that? The trick is put that bar on the same side as the other bar and then go away, moving over to the other side, and then when you bring it back down, you're gonna fix the green, and then you're gonna fix the blue just like that. So not too difficult. Once you have them across from each other Now you're gonna start solving on the sides. You can pick any color that you want to solve. Why was one I'm gonna go with? Because it's pretty much already done. I just have to find the other white piece, which is right here. So this is another pattern that you may run into when you run into this, you have to think you have to pair this up into two different pairs of two. So if I bring it up, if I bring this white piece up like this, I am just left with the same pattern. And then when I bring it back down, I'm still gonna be the same pattern. So what you want to do is make it so you have it like this. So when you bring this one up, it'll pair with that one like this, you move the other pair to in the bag, then you can just step it aside and bring it back down. So now we have white done. We know opposite of white is going to be yellow, so I'll turn it around and I'll make the yellow side. Now you can just go here and there and there. If you want. You don't have to do the opposites. This is just to help me keep track of how I go about making my centers. So we have two yellow in this section and we have another yellow over here. I could bring this yellow up like that, impair it, moving over to the side and bring it back. Now, I have a bar, a yellow dot here, and I have this l This is the same situation that we were in a little bit ago. Where if I bring it up, I'm kind of stuck. So what, you want to dio move it down like this? So that way, when you bring this yellow up to this yellow, you have your bar, you have the more back here, step aside and bring it down. And there you go for last pair of centers. You're gonna want to look at the orientation. This is the way I like to remember it. Red, white, blue, like the American flag. So this will be the red side and, you know, opposite red is gonna be orange, so we'll make this side the red side and notice. We have a diamond pattern here. If you look on the bottom, we have the other two red ones that we need on the bottom. If you move this one up here, you create a bar so we can actually move this to the side, fix our centers. And now we have this three shape and then one down here. So if we bring this one all the way up here, we're gonna have another bar. But let's say we didn't. Let's say we had it like this when you brought it up. We have opposites, and we don't want that. So we're gonna move it to the side until we get a bar moving over and then bring it down. You have officially completed all of your centers. 4. Edge Pairing: So I hope you guys were having fun with this course so far. If you get prompted to review the course, please take a second to give it a quick review. Let me know what I'm doing. Good. Let me know what I'm doing. Bad. That way I can help improve the quality of my videos and give you guys some better content . Now that you have your centers completed, we're going to start building our edges. This is actually a pretty easy thing to do. So what you're gonna do is find any edge that you want to pair. So let's go with this right and yellow. You're gonna position the red and yellow on the year, this side or on this side, As long as it in front of you. And it's on one of these sides. It's all you got to do now. We're gonna locate the pair of that one, since it's going to be another red and yellow edge. So locate that red and yellow edge, which I have mine right here. And what we're gonna do is have them across from each other like this, with opposite colors facing you. So, for instance, edges have two colors we have on this one. We have yellow and we have read. So what's facing me right here is yellow. So I need to make the red one face me on the other side. The way I can do that is simply by stepping aside and inserting it like that. Now that we have this understanding, we're going to be able to pay our edge. First thing you have to do before you actually do the pair is you have to make sure that if you noticed, this is a higher and this is a lower. This is upper. That's a lower on the lower side. Meaning this side. Make sure you have a an unsolved slot or unsolved pair right here. Then you'll be able to start. First thing we're gonna do. You're going to move this over so that way you pairing them up just like that. And yes, I understand your centers have been messed up. We're gonna fix it, so move it over the upper to the lower one. Now, if you notice that one that we had, that's not solved up here above the lower one. When we move the centers or you do this, Uh, this movement right here, it's gonna move to the back. And what we're gonna do is we're trying to move this up here, so we're gonna do it like this, are you are prime, and then you're just gonna fix your centers. It is easy is up. This is the pair we just did. You can leave it up there, put anywhere you want, just leave the fronts and preferably just up here on the other side, a little free. So that way we can set up the other pairs. Now that you've done that, I'm gonna do another example for you. So I'm gonna just find another one. I'm gonna go with this one. We have blue and yellow, so I find it's pair right here blue and yellow, and we have to make sure opposite colors across from each other. So I'm gonna step aside. Insert it like this. So I have blue facing me, and I have yellow facing me. So it's exactly the same situation we were in before. Now there's the upper one and the lower one. I'm gonna make sure that the lower one does not have a solved slot here or solved pair. And that's not a soft pair. So we're good to go. So first thing, I'm gonna bring the upper one to the lower one. I'm gonna bring this pair up. Here Are you are prime, and then I'm gonna move the centers back. There you go. You're going to repeat this process for the rest of your edges. So here is an example of a case where you can't find an edge on top that is not solved. So, for instance, this is the parent working with is the blue and white. And then there's the blue and white over here, they're already set up and ready to go. But on the lower side, this one is solved. That one solved that one solved, and so is that one. So I have nothing really to work with. So what I can do is I can look for one that is messed up. For instance, all of these down here are as well as this one back here on what I could do is let's say this one back here, I could just move it into the top layer. It doesn't matter if there's solved one back here that we're gonna fix it just like the centers. And now I have an unsolved pair. I'm not pear, but Unsolved edge slot. So now I'm going to position that above the lower one I'm working on. This is a lower one. So I push it there, and we're gonna do the same thing as before. We're gonna move the upper to the lower. We're gonna move the pair in front of us up there. So this time is gonna be l prime. You prime l and then fix your centers. And there you go. Now, there may be a situation you're going to run into where you're on your last pairs and you're not able to figure out how to do it. I'll show you that in just a second. 5. Edge Pairing Special Case: This is the exact situation I'm talking about. So you have this one right here, orange and white, across from orange and white, opposite colors. But everything here is solved. Everything in the middle layers solved, everything on the bottom is solved. So you have nothing to really work with except the other side. Now, if you notice the situation, you have orange and white, orange and white. But the other one that's next to it is green and yellow. And then you also have green and yellow. So both of these are able to kind of go across from each other. This is on Lee going to really happen when you have your final two edges. So in order for you to fix this first thing we're gonna do is make it same colors facing you. So you want to see white here and green here? So let's just knock that out. You can do that simply by just flipping it just like that. It's now we have white, orange, white, orange, same color facing me. And then you have green, yellow, green, yellow, same color facing you just like this. Now, this is going to introduce your first algorithm. So the first album that it's not too complicated. Pretty easy, basically, you're going to do this. Not too bad, Right? So that will be it. Now we can you solve it like a three by three. Now, keep in mind there is something called parody that I'm gonna be getting to shortly while you saw it. Like it to be right through to get to the final layer makes it where you cannot solve it like a three by three. So stay tuned. Keep watching. Because I'm gonna cover that in just a moment. 6. 4x4 Example Solve: for those that may be confused as far as how exactly to solve this. Like a three by three. I'm gonna show you guys how I would solve it using, let's say beginners method just to that way, everyone's kind of on the same page. So I'm gonna start with white and you're going to start by building your white cross. So you have your edges. You have your centers. Same thing as a three by three. We have that lined up. I'm gonna move this one over, so I have this one just lined up. I'm gonna move this green and white to the green side. Move that down and then I have my blue white move that down. It's now I have my cross and then a Sfar. As beginners method, you can basically just solve your corners. The same corner is gonna be solved exactly the same as beginners method. So this corner belongs down here, and then we're going to do the same thing for the rest of the corners. This corner belongs down here. This corner belongs down here. And then we have one more, which belongs down here. Then you're gonna go for your edges. So this is an edge I can work with, which is red and blue belongs to red and blue. So we're going to do the same beginners method algorithm that we would in order to solve that case, We're gonna do the same thing for the rest of the edges. Okay, We just got one more to dio. So this is going to be parody, and I'm going to explain this in the next video. 7. Parity Cases: So when you run into parody, you're going to be able to quickly recognize this parody whenever you have a backwards l like a normal three by three and a line at the same time as you notice on a three by three . This is impossible. However, on a four by four, it is entirely possible. And that's why we have the parody case. There is another parody case, so stay tuned for that one as well. Once this one is done, I'm gonna post the algorithm up here for you. And I apologize. I am not able to do it slow. Um, I just I do this whole thing off of muscle memory at this point. Whenever I do it slow, I just screw up the whole algorithm, so I'll try to go slow as I can, but at least you'll have the algorithms. That way You guys can have it face. You're just like this. If you run into this case and just follow the algorithm in order to execute it so it will look a little bit like this. And yet again, I apologize. I can't do it slowly. I just have muscle memory. I've done this probably 20 times. I cannot do it slow, so just follow that algorithm and go ahead and watch my video again if you need to in order to execute this case. But this is the most pain in the butt algorithm that you're probably going to come across and any four by four. So once you understand that algorithm, our that algorithm, then it's out of the way. And the other Perry case we run into is significantly easier. You can do it after maybe a minute of practice. So now we're going to move on to continuing to solve it like a normal three by three. Now the final parody case that you may run into look something like this. Where yet again, it's impossible on a three by three, but you have a double edged swap on a three by three. This is possible, however, The side effect is that at least two corners have to switch as well. So two corners or maybe two other edges. It's the only way that this can really happen. So on a four by four, this case is very easy to solve. You may run into a case where the edges that are swapping across from each other. Or maybe they are even adjacent and the other two are solved, so it may look a little weird. However, this one is much, much easier to handle. In the other parody case, the algorithm will look like this and you're gonna execute this very easily. So it's just gonna look like this. Just follow me and follow the algorithm, and that's it. Once you're done with this, it may mess up what you had already solved a little bit, not on the top, but on the sides and for you. If you're using a well appeal Oh, then all they have to do is just continue with what you were doing and that should solve it . There are no other cases. That's it. That is a four by four. In a nutshell. I hope you guys enjoyed the course. If you guys get prompted to review the course, please review it. Let me know what I'm doing. Good. Let me know what I'm doing. Bad and yet again. If you guys are interested in picking up this cube this matter or any of these cubes I have in the background, feel free to look in the course description so you guys can pick some of that stuff up for yourself. Just one also touch on this, you guys. I will be posting an advanced tutorial on this. That what? You guys can learn how to solve it a bit faster. So when you're comfortable, go ahead and look at that course. If there is a video after this one, then there will be that course available. So go ahead and take a look at that one. And hopefully you guys will enjoy that as much as you. Hopefully like this one. So been a pleasure. And I'll see you guys in the next one.
