Rubick's Cube.

[Mick F]

Here's the instructions I've written down .................. if anyone wants to do it!
It's not 100% the way I remember it, but it works just about the same way.
Minus signs mean anticlockwise.


First Slice

Firstly, make a cross, correctly positioned.
Next, get the corners of the first slice in position and correctly orientated to complete the whole face.

No instructions for this slice. Just do it to get to know the cube.


Middle Slice

Make the first slice the bottom where it will remain for the rest of the cube.

Note that some or all of middle slice corners will be incorrect. Also check that one, more or all of the middle pieces in the top slice should actually be in the middle slice. These are the ones to aim at.

Pick any one of the four side faces to be the front face.
Rotate the top slice to put one of these top middle pieces so that it is on the right face.

Do this move. (minus sign means anticlockwise)

U- F- U F U R U- R-

Repeat, until the whole of the middle slice is correct. It could be that the piece will go in the wrong way round, but do the move again to take it back out. Repeat again to put it back in the correct way round.



Top Slice (part 1)

Get a cross on the top. Pick any face you want for the front, and do this move.

F U R U- R- F-

If you get a straight line, put it horizontally. Repeat the move.
If you get two correct, put them at the back left. Repeat the move.



Top Slice (part 2)

Get the top cross in the correct positions.

To swap the front and the left do this move:

R U R- U R U2 R- U

You need to orientate the top cross so that the front and left pieces are in the right place to swap. You may need to do this more than once.


Top Slice (part3)

Get the four top corners into the correct place. Don’t worry about their orientation.

Find a corner in the correct place and rotate the whole cube so it’s on the front right.
If no corner is in the right place, do the move anyway so that one is correct.

Do this move:

U R U- L- U R- U- L

You may have to do this more than once.


Top Slice (last part)

Hold the cube so that the top right corner is incorrect.
At this point, there could be one, or two corners actually correct, but turn the whole cube so that one of the incorrect ones is top right.

Do this move twice ……….. then another twice if required to get the chosen corner correct.

R- D- R D

Do not worry if the cube looks very messed up after this sequence. You MUST hold the cube exactly as it was despite feeling that it’s wrong.


Rotate the top slice - holding the cube still - to put another incorrectly orientated corner at top right, and do the above move again twice ………… and another twice if required.

Repeat for all the incorrectly orientated corners.

The cube will only be non-messed up when all four corners are correct.

Hi,
So you taught yourself the solution........................

I wonder how many did and did not receive tuition?

I like solving puzzles and admit I never lasted long on the cube.

But I liked the Wooden Chinese Puzzles even if it just a advanced lego

I never understood why people wanted to unravel those I have better things to do with my time

And the 'bent nail' ones too I like having competitions with some of my older grandchildren.

Sudoku for example, or nothing, that is good, just sit for a while, I think it is called meditation

Solving puzzles is great and I find them therapeutic.........................But going online / whatever is just cheating for me!

Not solving puzzles can take me into a dark place, but that does not mean that I will shrink from any.
Plagiarism.....................

Grandson aged10,presented me with a four each side cube last evening and couldn't even manage that
He then beat me at chess

I was pretty handy at Rubik's cubes in the 80s. I was third in a competition in my school. I don't remember exactly how fast it was, but me and the second place person were pretty close, and around one minute. The first place person did it much faster, something like 29 seconds. Of course it was no where near international competition fast, but 29 seconds seemed impossibly fast to me then, and now records are like 5 seconds.

My daughter has one. she and her friends can do it, but I had a little go & couldn't remember. I'm sure I could again, if I practised.

You can do the Cube faster if you oil it. Dry, they are stiff and "clicky".

Down to a couple of minutes now and if I really tried, I could get down to a minute and a half.

Or get a decent cube

All this talk of slices is making me hungry, I'm a whole meal seeded crust person. I'm putting the toaster on now.

I use(d) ruwix.com for algorithms etc.
Works well enough, I just need to learn the parity algorithms for OLL/PLL - but they are long

But can you get all the slices to match up once they've been mixed up,if so how fast?

PS,no eating any,that's cheating!
