How to Solve a Rubik's Cube - Part 6 - Top Corners

All right , this is step six of how to solve a Rubik's cube .

What you should have at this point is a top yellow face which is completed and is one solid color .

And you should also have two bottom layers which are also complete .

This is the second to last step .

So there's only one step after this .

So we're almost there .

Um What this step is going to do is it's going to reposition these four top corner pieces so that they're in the correct orientation .

And the algorithm which we're going to use is right counterclockwise , front , clockwise , right counterclockwise back 180 right clockwise , front , counter clockwise , right , counterclockwise back 180 right 180 .

And it's a relatively longer algorithm than previous steps .

So it might be a good idea to write it down or to just pause and possibly rewind the video to go back and watch closely as I go through the steps on the actual cubes .

OK .

So in order to actually perform the algorithm , what we need to do is assign a right , a front and a back um face because those are the three faces which are used in the algorithm .

So what you want to first do is you want to look around the cube on the top layer here , you wanna look for two adjacent corners which have the same color .

So these don't have the same color .

This one is blue and this one's red , you don't want to pay attention to this top layer edge piece because that has nothing to do with this algorithm .

So if we look around these two are also different , it's red and orange and these two are also different .

If you look at these two though they are the same .

So when you find two adjacent corner pieces which have the same color , those corner pieces designate this face as the back face .

So this would be the back face , this would be the front face and this would be the right face in this case .

Now , if you're looking at your cube and you don't find two adjacent corner pieces which have the same color .

Well , this cube also , if you look around , it also doesn't have two adjacent corner pieces which have the same color .

So in that case , you can designate any one of these side faces as the front or the back face or the right face , it does not matter .

So let's go through the steps and try the algorithm out .

Let's do it first on the cube that does not have two adjacent corner pieces which have the same color .

OK .

So if we perform that move , so it doesn't matter which side you designate as the back or the front .

So let's just designate this as the front and this as the back .

So if we do that move , which is right , counter clockwise , front , clockwise , right , counter clockwise , back , 180 degrees , right clockwise , front , counter clockwise , right , counter clockwise , back 180 degrees and right 180 degrees .

What you'll then notice if you turn the cube around is that there are now two adjacent corner pieces which have the same color .

In this case , they're orange .

OK .

So if we take the other cube now and we look at these two adjacent corner pieces which have the same color .

These are going to be designated as the back face .

Now , as I said before , so if I turn this around , this would be the front face then because that's the back face and this is the right face .

So if we perform that move again , right , counter clockwise , front , clockwise , right , counter clockwise , back face , 180 degrees , right face clockwise , front face , counterclockwise , right face , counter clockwise , back face 100 and 80 degrees and right face 100 and 80 degrees .

Now , if you look at the cube , you can see that one side is actually totally finished .

This side is now in the proper orientation as far as the corners are concerned .

And so are these two sides ?

Now , it doesn't always happen that you have a complete side .

Um After you finish this move , this might actually have a different edge piece here .

So all four sides might have what looks like this face or this face .

So if you perform it with the other cube , right face , counterclockwise , front , face clockwise , right face , counter clockwise , back face , 180 right face clockwise , front face , counterclockwise , right face , counterclockwise , back face 180 and right phase 180 .

And we look around , we also have the same thing .

So we have a complete side and we also have three sides which are not finished .

OK ?

So once you have something that looks like this or even if you have a different edge piece in this position , you're ready to move on to the final step .
