## To think the rubix cube is impossible to solve.

I have been trying for weeks since my birthday on 14th December.

It just can't be solved

I've never even got a single side done. I just don't understand it.

There was a puzzle called the dragon lock about 20 years ago and it was supposed to be fiendishly difficult but I could do that one. I suppose it is just about how your brain works.

I learnt how to do it dead quick when they were first out in the 80s but this was by following one of the printed solutions. I never actually "solved" it for myself IYSWIM

dd1 can do it in 45 seconds.
She raised a fortune for charity doing it in school assembly. They all bet on her time, teachers too. She got just over £400.00.

My ds can do it really quickly and so can dgs whereas I never managed more than one face.Mind you I cant get solitaire [the one with marbles] out either and I cant do a jigsaw with more than 100 pieces

Yes, remove stickers and basically cheat

I can do it - I learned the method thirty-odd years ago and never forgot. And have now passed it on to my kids.

My dad taught me how when I was a kid, there's a set of moves that will do it every time. First the corners, then the edges. It was really easy to do when you knew how, obviously! Can't remember it now though...

I could do two layers, but have forgotten the instructions on how to complete the third layer.

It was years ago. I need a cube, now

OhyouMerryLittleKitten Mon 31-Dec-12 12:26:11

I need to buy a cube now.

DH could do it behind his back. He's an engineer. I couldn't do it even following the instructions in the book .

SoupDragon Mon 31-Dec-12 12:06:56

My method was:
Top face (I always went with orange )
Bottom corners
Middle layer
Bottom layer

I must google how to place the corners...

Using the instructions it has just taken me most of the morning to solve it!!! But it is now done
Next challenge will be to do it without instructions but not today.

Solution I used was

White cross with matching the colours below - middle and one above - on each side. Order blue, orange, green, red
Then did white corners
Next middle and top layer of each 4 colour
Then yellow side

I can do it,

I can also teach you to do it.

do a face(white) and work down in slices,

then place the corners in the right location,

then turn the corners so they match the middle pieces on each face,

then the middle bits around the bottom slice,

that's the basic fool proof method,

I can talk through any moves.

YABU in saying you think it's impossible to solve, when there are clearly thousands of people who can do it. If I remember back to my childhood, I'm sure the 'record breakers' used to do it in under a minute.
Personally, I've never managed to do it, but then there's loads of things I've never mastered, doesn't mean they are impossible to do.
I hope Mr Rubik made a lot of money from it, and didn't just sell out for a few dollars early on

SoupDragon Sun 30-Dec-12 23:43:49

2 mins 30 seconds was my best ever time.

Sadly I can't remember how to get the corners in place now which is rather important.

It's really easy though - all about learning how to manipulate a given block into place without disturbing the others.

I bought not bout.

Sun 30-Dec-12 23:41:58

Give it to a small child they can do them.
Also my Dh can do it in about 10 minutes, Ds takes long about 20 and other Ds and me, not in a million years.
So we went out and bout Dh the more difficult one, www.amazon.com/Winning-Moves-5011-Rubiks-Cube/dp/B0001CU16A and bloody pain in the arse finished it too.

VonNeurosis Sun 30-Dec-12 23:15:37

Why not up the ante and try solving them hurtling to earth in a rubber dinghy?

blackeyedsusan Sun 30-Dec-12 23:14:48

I can't personally. the closest i got was 2 layers and the cross on the bottom... however, there were other pupils at school who could solve the damn thing in seconds...

KellyEllyChristmasBelly Sun 30-Dec-12 23:10:45

I can't even do the flat ones where you move the squares around

Sun 30-Dec-12 22:58:04

I don't know about reasonable, but it would seem that you don't understand what the word "impossible" means.

there's a brill video set on YouTube that i followed.

works every time

Sun 30-Dec-12 22:55:53

It's just a bunch of algorithms. My DS can do it in about 2 mins, he is age 9. He taught me and I can do it in about 4 mins.

Sun 30-Dec-12 22:53:06

I memorised the moves when I was about 11 (when the Cube came out) and as long as I don't think too hard when I'm solving it, I can still do it. It's like my physical memory still works but the brain one doesn't,

Had to work out the solution to the 4x4 though, then I made the mistake of lending that Cube to a school friend and they broke it. Never got another one. Sniff.

Yet things come full circle. DS is fascinated by the 3x3 and I'm sure one day he'll crack it.
