  • Do you ever wish you could figure out how to solve one of these things [The Rubik's

  • Cube]? Well after watching this video, consider your Problem Solved!

  • 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! But while you're throwing that party, make
