Rubik's Cube Help

School's over. I have another couple months to do nothing until a bunch of psychologists decides on my future in the next 4-10 years on the basis of my drawings of people, homes, trees and all this psychological crap.

Life was pretty meaningless in the last month and that's how I like it, or at least that's what I thought.

Err... anyway, i'm bored and I decided that in exactly 7 days I will be able to solve a Rubik's cube in less than 5 minutes, on average.

So how do I do it? I found lots of internet sites with nice applets and whatnot, but all of them seem to assume too much about my capabilities. :) Even in the best of them, I manage to get lost after a few steps.
My problem is that my "visual understanding" is very poor. All those sites think that after one example of a move I can figure out how and when to use it in the future, while at best the only thing I can do is to stare on the damn thing and try to convince myself not to give up.

Books are out of the question since our city library sucks and i'm not going to spend any money on this.

The first poster who finds a REALLY good site that explains everything from step 1 to the end in enough detail and simplicity for a 5 year old to understand, and with lots of pictures... will choose a sig that I will use for the next week. :D
 
Hmm. I found there was only one important trick one needed to know (a sequence of 5 turns IIRC). The first time it took me some 7 hours to solve the puzzle, by the third time I had it down to 20 minutes and got bored. Never needed any sites or books.
I must still have that thing somewhere.

Well, at least your bad music memories are BAD music memories. Think of me. I grew up with Disco. Yich.

Rubik's cube is basically unavailable here. Where did you find it?


I'm with Ribannah. I solved it a couple times, learned a few tricks with the stripes and checks and have not messed with it since.

PS If you want a challange, try the SOMA puzzle at this site http://yavsoft.com/soma/
 
Aha, an apprentice cuber!

Well, those web sites really describe it very well and probably better than I would ever care to describe. However, although they are always abound in content they are often lacking in theory. So here is a few basic tips on the (3x3x3) Rubik's Cube:

The first thing you ahve to realize about the cube is that the goal is not to match the colors. The goal is to match the blocks. There are also only 20 blocks you need to manipulate: 8 vertex blocks and 12 edge blocks.

Most importantly, you need to realize that algorithms have inverses, mirror images, and can be performed anywhere and on any set of blocks you can manage to place in the formation dictated by the algorithm. For example, if you have an algorithm to rotate 2 adjacent vertex blocks but you want to rotate 2 vertex blocks at the opposite end of the cube, you can do a 180 degree rotation to make the two blocks adjacent, perform the algorithm, and then rotate back.

Also, there is a final "suggestion" I have for you if you are dedicated and gifted enough: you can try to solve it completely on your own. Yes, it is possible and people have done it (although some group theory would help tremendously).

:wallbash:

Were you even born yet, then? ;)

Those were MY bad memories (that, and the disco that came before)....

Cripes. I never looked on it as an Algebra problem. It would be a group, in the strict sense, of morphisms wouldnt it. I just plunked at it til it was done.

PS I met the world champ once. He was Japanese, but living in San Fransisco. It was at a Pente tournament.
 
Don't waste your time with these puzzles, learn chess. It's a much better game. :D

I thought Pente had been "solved"?

Learn Go, its a better game still. Bridge is good if you like more social games.

I had not heard that Pente had been solved. Do you have a source. I used to be rated.

Chess isn't as fun anymore with incompetent people memorizing openings and lamers (at least online) using ChessMaster and Fritz.

Go! is the way to go (pun intended) nowadays because currently there is no efficient algorithm for it. Also, it is the epitome of what a timeless game should be: few and simple rules, but having an almost limitless amount of variations.

No kidding about people using computers for their online games. Its as easy to spot as a translator program on this site.

Since it was brought up, Pente is an almost perfect online game. The whole game is typically less than 25 plays, often much less. Dweebo's Stone Games is an excellent site. There are computer downloads available.

PS Another math type that likes Go. I would say "Go figure", but that would be lousy form.

Card games, eh?

My favorite card game is Mental Jujitsu, followed by Liar's Poker. One can never get bored with Mental Jujitsu.

Really? I usually fill up half the board.
 
Just get a Rubix Cube where you can place stickers of all the colors on their sides. Trust me, it's a lot quicker this way.

I bet none of 'em can beat a good game of five handed euchere

Ambitious.

I imagine every guide has it's own way of "thinking about" Rubik's Cube, and you haven't yet found one that fits your way of thinking. Nihilistic showed you his, for example. I'd deal with it mechanically, because that's just how I understand everything (yes, everything :ack: ). Be careful which way of thinking you take on. An approach that gives quick results may actually handicap you later, as in the Phonics method of learning to read.
 
Nihilistic, Sean :

The problem is that all those sites are just not simple enough for me. I'm stupid or something. :D
 
I guess they're making it more complex than it really is, to show their sophistication.

I presume to solve it quickly you need enough short term memory to hold the whole cube in mind, all jumbled. That's not complex, just heavy. Can you do that with practice?
