Logo Scene "This is, Problem Solved!" This video is for anyone who has absolutely no idea what they are doing with a Rubik's Cube. All you need is a desire to learn how to solve it Before we actually get into solving this cube there's two things I want to teach you real fast. The first are the three types of pieces a cube has. First, you have these centers with one color, edges with two colors, and corners that have three colors on them. Now in order to solve the cube we are going to be looking at these center pieces which never move and therefore tells us which color the side will be when the cube is solved. So when the cube is solved this side will be all white, all green, all orange, so on and so forth. Now to solve the cube we are going to take each of these individual pieces and match up all their colors like this one. This is a white-red edge piece so we're going to match up the red with the red and the white with the white. Once you do that kind of thing with every piece on the cube, then it's solved! Now the way that we solve the cube is using algorithms, just a series of steps, and these are written by labeling each face with a letter and then having a superscript to tell you how to turn that face. So this face right here is the Up layer, and that's going to be labelled with a "U". "D" for Down. "R" for Right. "L" for Left. "F" for front, and "B" for Back. Now if you see just the letter, like just a "U" that means turn it clockwise. If you see a little "1", a little tick-mark that means turn it counter-clockwise [anti-clockwise]. And if you see a "2", turn it twice. So over here to the right you are going to see three things. You're going to see the "Set-Up", 'Algorithm", and "Glitches" sections. This is how I'm going to break up each step in the solve. The set-up explains the moves or things that you have to do before the second step, the Algorithm will work. Then the Glitches section explains special cases that you have to address even before the you can even get the Set-Up to work. A final note, feel free to pause or back up this video as needed also, check out the description to find a printable page that explains all seven steps. Now we can start solving the cube! The first step is to to make a cross on the bottom. Now you can do this with any color but we're going to start with White, just for simplicity's sake. So start by taking this white center piece and put it down in the bottom. Now our goal with making this white cross is to make it look kinda like this, where we have literally a cross, with all these edges matched up. Now in order to do that, we're going to start looking in the top layer for any edge that has white. We have two here, we're going to use this one for now. Now we are going to look at the other color on this white edge piece, in this case it's Orange, and we're going to put it right above that center, so in this case right here, orange is above orange. Now we're going to do a F2 in order to put it down. Ta-da! and that one worked. Sometimes, like with this piece, we have green as the other color, so we're going to put it above the green center piece, so sometimes when we do this F2, we notice this piece is backwards and so that's where we have to use the special algorithm that you see on the *bottom. Now the way that this algorithm works is you take this piece and move it right over to this position right here using the F layer, like that. Now this D layer where this piece was, is going to slide over, now this is going to drop down, and you're going to put the piece back. And that solves this piece without messing up the rest of your cross. Sometimes when you're working on your cross you'll notice, it's not done, but when I look in the top layer I can't find any of these edges [with white]. Now that means one of two things, either you have an edge stuck in the bottom layer in the wrong spot, or you have an edge, stuck in the second layer. Now this one's the easiest to fix, you just do a F2 to pull it out the same way that you would normally put a piece in. Now you can then go ahead and solve it, put it above its center piece and then do a F2 to bring it down. Now this one that's in the second layer, you have to use what's called the trigger move, and a trigger works by doing "up, over, down, back." And that will pull that out of the second layer into the top layer. You can then go ahead and solve it as normal. Our next step in solving the cube is to solve our 1st layer, which will end up looking like this. Now in order to do that we solve each of these corners, this one is solved, and this one is solved. Now in order to solve these what we have to do is to find one in the top layer like this one, that has white on it, look at the three colors on it, white, orange, and blue, and first figure out where this piece goes. Now in order to do that, we put a finger on each of these center pieces: white, orange, and blue. White, orange and blue. Now when we pull our fingers together we notice that our fingers are resting on a spot, that spot that our fingers are resting on is where this corner goes, and we have to put the corner above that spot. White, orange, blue. White, orange, blue. Okay, now we can use the algorithm, which is just the trigger move that you just learned. Up, Over, Down, Back. Now you may have to repeat that up to five times in order for that to happen. Now sometimes, you're going to notice that your first layer isn't done, but you can't find any corners with white on them in the top layer. That means you have a corner stuck in the bottom layer. Now in order to pull this out just to the trigger move again to pull it out. Up, Over, Down, Back. Now you can solve it as normal. You're doing a great job! You have one layer complete! Now the next step is to solve the second layer, which looks like this, notice two rows all the way solved. Now in order to do that, we're going to look for a piece in the top layer that doesn't have this center color, in this case yellow, so we're going to look for a piece that looks like this one, it doesn't have yellow on it, that's good! Now if you'll notice, we have these "Little Ts" that have been made by our first layer and the center piece. Now we want to look at this front color, the color that's on the side of this piece, this is blue. You want to match that up so you get this "Big T", just like that. Now the second thing we need to know before we can use an algorithm, notice there's two of them, is which direction this piece goes to. Now the way that we find out where this piece goes is similar to the [1st layer] corner. We have a blue and a red, put a finger on the blue and the red, pull them together, and that's where this piece goes. Blue, Red. So this piece goes to the right of where it is now, so we're going to use the "right" algorithm. Now both of these algorithms actually work very similarly. They both start by turning the piece away from where it needs to go, then you do a trigger (in this case since it's the "right" algorithm, we'll do the right trigger: Up, Over, Down, Back), then we're going to bring this piece that's in the right over, turn the top layer to the right, and then back down into the right, just like that. Now we look for another piece, like this one, again it doesn't have yellow, look at the side color, blue, and we make this "Big T." Now we are going to ignore these just so you can see that "Big T." Now we know this one is blue and orange, blue orange, they go right here, so that goes to the left, so we'll use the left algorithm. Again, we turn it away, use a trigger, but this time it's the left trigger: Up, Over, Down, Back. Bring this piece that's in the left over to match up, turn the top layer to the left, and front layer back down inserting that to the left. So sometimes while you're solving your second layer you're going to look and you're going to say, "I don't have any edges that don't have this top color, yellow." That means that you have some that are stuck. That will look like this where the pieces are backwards, or it could end up looking like this where a piece is just in the wrong spot either way, to solve either of these cases use the same method. You just pretend that this piece would go here or here. You just use the algorithm that you did before, in this case the right algorithm, and this piece has been pushed out. You can look at the side color, green, match it up to make your "Big T", and then you can solve it as normal. Now on to the Third Layer! We're going to start solving this similar to the first layer. Where we started with a cross, we're going to start with a cross up here, so when we're done it's going to look sort of like this. Now notice the edges aren't matched up, that's going to be solve in another step. So in order to do this, if you look across the top you're going to see that there's four pictures there, you have a "Dot", an "L", a "Line", and a "Cross". Now each of these are possible cases that you can get after you finish your second layer. In this case, ignoring the corners, we have a dot, now in order to get from one case to the next, you use the same algorithm, which look like this. Front, your right trigger (Up, Over, Down, Back), and undo that Front turn. Now, again ignoring the corners, we have this "L" shape. Now you can see from this picture that it goes up in the top-left, just like that. Do the algorithm again, Front, Up, Over, Down, Back, Undo Front. Now we have the line, hold it parallel to your shoulders, and do the same thing. Front, Up, Over, Down, Back, Undo Front, and now we have out cross, again, ignoring corners. The next step to solving this cross is to match up all of these edges. Now upon first glance you may look and see, there's none that are done, but if you turn the top layer once or twice you can always match up at least two, in this case we have this green one, and this blue one, now our ultimate goal is to have it look kinda like this, where all four are matched up. Now again, notice in the top, there are *three pictures. We have this "Line" which is made by this matched-up edge, this matched-up edge, and the center. Notice, a line. Now our next goal is the "L" which is these two edges matched up. Now in order to go from step to step, we do the next algorithm. This is called a "Sune", just a fancy name to help you remember. This works by working with these two pieces right here. We are going to start, almost like a trigger, Up, Over, and Down, but instead of going Back, we go Over again. Now we are going to bring this back Up, then we're going to do Over twice, and back Down. Now we have this "L" shape, these two are solved with the center, and these two aren't, they need to be flipped. So if you see, the "L" goes in the top-right, and we're going to do this again. Up, Over, Down, and instead Over again, Up, Over twice, and back Down. Now you are a single turn from having your cross matched up. So our next step after solving this top cross is to put each corner in the correct spot, which when we're done, will look something kinda like this. Now in order to check and see if a corner is in the correct spot we look and see where it needs to go to be solved. In this case, yellow, blue, orange; yellow, blue, orange, notice that our fingers are on the corner we just checked. It's okay that it's turned wrong. Now if you'll notice across the top we have three diagrams, one with zero checkmarks, one, and four checkmarks. Each checkmark represents a corner like this that is in the correct spot. Most of the time you'll have one. So we're going to hold this in the bottom left corner as we can see, and each arrow means to the algorithm once. This is called the "Riklas" and it works like this. Right up, top to the right. Left up, top to the left. Right down top to the right. Left down, top to the left. Now you may have to do that up to two times in order to get every corner placed correctly. We are now super close to having the cube solved! That's our next goal! So in order to that we're going to take one of these corners that's not turned correctly, and hold it in the bottom right. Now we're going to use the trigger move, but upside down. So we're going do it like this, Down, Over, Up, Back. And we're going to repeat it until this yellow is up here on the top. Down, Over, Up, Back. Now hold it right there! Don't do anything else! You may look at the side and see, "It looks like I just completely messed this up!" Trust me, it comes together, and it's kind of magical, but if you don't do it just right you'll have to go back to the second layer, and that's no fun, so in order to keep it safe, only turn the top layer in order to get a new unsolved corner in to place. Now you repeat that upside-down trigger in order to finish solving it. Down, Over, Up, Back. Down, Over, Up, Back. Down, Over, Up, Back. Down, Over, Up, Back. And you're a single turn away and it's solved! Go ahead and party hard! You just solved the Rubik's Cube!
