How to solve the cube

 

 

Information about the cube

 

The cube is solved in layers, starting with the white face, then the middle layer, and then the last layer (yellow),

               1st Layer                                         Middle Layer                                 Last Layer                  

 

The centre pieces on the cube are always fixed relative to each other, white is always going to be opposite yellow and

red is always going to be opposite orange and blue opposite green.

There are three different types of pieces,

1.       The centre pieces, with one sticker

2.       The edge pieces, with two stickers on it

3.       The corner pieces, with three stickers on it

It is important not to look at a piece with white on it and call it a white piece, look at the other colours on it, if it is an edge

 piece and it has white and red on it, then it is the white and red piece, the only white and red piece, so the only place for it

is in between the red and white centres.

If the piece has 3 colours on it, white blue and red, then it once again is the one and only white blue and red piece and the only

place for it is in between the red white and blue centres,

So the 54 colours on your cube have been shrunk down to only 26 pieces,

 

 

 

 

Notation

 

Each side or face of the cube has a name abbreviated to a letter,

 

U =  Top or upper  face               F  =  Front Face           L  =  Left Face

D  =  Down or bottom face         B  =  Back face            R  =  Right face

In the solution I am going to be using the word algorithm a lot, this doesn’t mean it has anything to do with maths, an algorithm is

 just a sequence of moves,

 

For example: U2 D2 L2 R2 F2 B2

 

A letter means turn that face clockwise 90 degrees

An apostrophe after a letter means turn it anti clockwise,  example: U’

If you are unclear as to which way to turn it then look at the face and do it, B and D can be confusing

A 2 after the letter, U2, means turn it 180 degrees

The F in the illustrations indicates which face is the front for that section

It is important to keep the F face the same throughout the algorithm, if the F is on the blue centre then blue will be the F face for

 that algorithm. Hold it with blue facing you at all times (unless your checking which way a face should be turned).

On of the more common mistakes made while learning is starting with the wrong F face, or accidently changing the F halfway through

 the algorithm.

 

 

Try the above algorithm on your cube, and see what happens, re do it to put your cube back to normal.

 

Before trying to solve the cube please read the whole tutorial the whole way through, and then while solving, read each section once

 again before starting it.

 

 

 

 

 

 

 

 

 

 

 

The Solution

 

1st layer

Step one;   The Cross

 

The first thing to do is form a cross on the white face, this is pretty much common sense, but there are some techniques to help.

The best way to approach it is by finding a piece, then find where it’s suppose to go. Start with the white and red edge, find it, and put

it on the bottom layer, then twist the bottom layer until its under the red centre. Then turn the red centre 180 degrees so that it forms part of the cross.

      The Cross                                        If you a piece is backwards and it looks like this,

                                                               then do the alg:   F’ U L’ U’

                                                               Note the F in the red centre, this implies that red is the

                                                               Front face for this whole algorithm,

Step two corners,

Place the correct corner piece, In this case the red white and blue piece, directly under the place it has to go, If the piece is in the correct

place but just turned funny that’s fine too.

For example, find the red white and blue corner. There are three places it can be.

1.       The bottom layer, so simply twist the bottom layer until its between the red and white centres.

2.       It’ll be in the correct place but just turned funny.

3.       It’ll be in the top layer, but not the correct place. Just turn either of the faces that its attached to 90 degrees so it moves down to

4.        the bottom layer, twist the bottom layer twice (180 degrees) and then put the face that you moved down back up (to reform your cross).

5.        The piece is then in the bottom layer and your back to option one. 

 

               Option  1                                            Option 2                                     Option 3

Do the alg:      R’ D’ R D   and remember where the F is. (blue!!)

The alg will have to be done between 1 and 5 times for the piece to go in correctly,

Do it to all four corners of your cube and then it should look like this

                                                                       1st layerdone.bmp

The middle layer

 

The middle layer is the easyiest layer, there are two algoritms and only four pieces to put in the correct place,

Turn the whole cube upside down so that yellow is now the top or U,

This is how its going to be until completed.

 

Position the correct edge piece above where it has to go like this;

 

Situation  1

The edge piece wants to move down and to the right, 

midedle sit 1.bmpthen do the alg:    U R U’ R’ U’ F’ U F    

                                               Don’t forget to check which your face is.

Situation 2

The edge piece wants to move down and to the left

midedle sit 2.bmp  do the alg:  U’ F’ U F U R U’ R’

 

 

Sometimes the piece you are looking for is stuck and in the wrong place, then you have to put one of the last layer edges

 (one with yellow on it) in to ‘knock’ the piece you want out, so if the red and blue edge, is in between the blue and orange centres,

 find a last layer edge (yellow) in the upper layer, pretend its orange and blue, and put it in to free up the blue and red,

Or even worse the red and blue piece is in between the red and blue centres but it’s the wrong way round, again, just put a last layer

edge in its place, free it up, and put it back in the correct way, 

Use the above algorithms to put all 4 middle layer edges in place.

 

Now loads of your cube is done and it should look like this

The Last layer,

 

The last layer is the most difficult and complex, if you make a mistake in an algorithm then you can find yourself being sent back to

 the start, but have faith, and persevere and you will solve it,

 

Step one,

 

The yellow cross

After completing the 1st two layers the yellow face of your cube will have one of the following patterns on it, do the corresponding

 alg to your pattern,

We are only dealing with the edge pieces now, ignore the corners,

The F face is always the one at the bottom in these pictures, and yellow is always up, U.

stripe.bmpbackwards l.bmpneither.bmp

 

     F R U R’ U’ F’                      F U R U’ R’ F’                 Do either of the alg, then re examine,

 

When you have the cross it is very unlikely that the second colour on each of the yellow edge pieces matches with the centre that its

next to, that doesn’t matter, as long as you have a yellow cross on top its fine, they get moved into the correct place later,

 

 

 

 

Step two,

 

Putting the corners in the correct place,

 

The goal of this step is to put the corners in the correct place but they don’t have to be turned the correct way round,

For example the red, blue and yellow piece could be in between the red, blue and yellow centres, but red could be on top, this is

ok for now, they will be turned round later,

 

You are guaranteed to have two in the correct place, either two next to each other, or two diagonally across the cube,

 

It may not appear so and you may have to twist the yellow face round a few times, but you will be able to get two in the right place.

The tick represents the ones in the correct place, the X represents the ones in the wrong place.

 

Again, remember where your F face is and line it up correctly.

2correct 1.bmp                                       2correct 2.bmp

        L U’ R’ U L’ U’ R U2                     or                                 L U’ R’ U L’ U’ R U’

                                                                                                             And then re examine and you will have two

                                                                                                           In the correct place,

 

Remember in this step we are not trying to get all the yellows on top, just the corners in the correct place, but not spun round correctly,

 spinning comes next,                  

 

 

 

 

Step 3

 

Flipping the corners around

 

There are 8 different options as to what your cube will look like on top, but there are two important ones, and luckily, only two algorithms

 need be learned.  If you don’t have one of the following pictures then do either of the algorithms and you should have them. If not try the

other one, you may go round in circles a bit you will start to notice patterns yourself and learn which algorithm to do to each of the 8 options.

But don’t worry about that for now, just pick one and hope for the best.

The two appear very similar but if you look closely the yellow dash around the outside represents the yellow sticker on the side of that piece.

 

llflipping2.bmp                                                       llflipping1.bmp 

       R U R’ U R U2 R’ U2                            or                                        R’ U’ R  U’ R’ U2 R U2

 

Your yellow face should now be complete, but again, don’t worry that the edges don’t match the centres.

 

 

 

Step 4

The last step,

 

By now your cube should be almost complete. The yellow face should be complete but either 3 or 4 of the last

 layer edges should be in the wrong place. If they’re not then you’re done and you got lucky.

If you have 4 pieces wrong then you can chose either of the algorithms, do it, and then you will have three wrong,

these two algorithms are very similar, except the way you twist the U face decides whether you move the pieces in

a clockwise or anti clockwise direction,

Put the edge piece that’s in the correct place on the left. Have a look at the piece closest to you; does it want to be

 in the back face? Or the right face? The arrow in the picture denotes where the piece is going to move from and too.

The tick represents the one in the correct place.

Be careful with the B and B’ moves, turn the cube round and look at which way your twisting it.

          R2 U’ F B’ R2 F’ B U’ R2                            or                                   R2 U F B’ R2 F’ B U R2

 

 

And your done.

The cube is finished,

 

Afters,

As you do the algoritms again and again you will start to notice patterns in them, alot of them are very similar.

 You will also start to remember them without even trying if you play with your cube enough and run through

 this solution. You will also start to understand the way the cube works and as a result start to spot little shortcuts

 and ways to make it that little bit quiker.

With this solution you should be able to solve the cube in under a minute.
