Unless you know exactly where you went wrong and all the steps since then, there is no good way to backtrack. Sorry.

*looks at the 5D Rubik's Cube*

...what... the... hell. It looks so confusing, and I don't even know where to start. O_o

Anyway, I'm not good with Rubik's Cubes. I even have a hard time with a 3x3 cube, and it took me a while to finish a 2x2 cube (yes, such a thing exists). So trying to do a monster cube, or a 4D/5D cube is completely out of question for me. XP

Well, it's good to here your responses, and I know am a little cube crazy, but whatever.
I also knew there are some good puzzle fanatics out there ... maybe I should have put this in the Brain Teasers Forum.

I am not particularly good with Rubik's Cubes. The 4D one was confusing, but I eventually mostly understood it. The 5D one, though... What the...

Just looking at the 5D cube made my brain implode. I stick with my trusty 3D cube.

I suck at Rubik's cubes. I have one, and I've never been able to finish it. And I've spent a long time on it, too.

Well, that's your problem right there. You don't get a side and then go for another side. You get a side. You call that the top. That side's not gotten until the faces on the outward edge are also one color to each side. The entire top layer is done. Then you go for the middle layer, and then the bottom.

I can get one side of the rubik's cube. Then when I'm trying to get the other sides, I always mess up the first side. At that point I do what CJ does, and peel off the stickers and put em in the right places.

It gives me a sense of happiness

They are fun to play with for a few minutes, then they get frusterating and I'll either throw it across the room or peel the stickers off. I'd like to hear anyone say that they never did that with 150% sincerity. I only solved the rubiks cube twice. I saw some crazy asian kid on the news who could solve one in 11 seconds!

My rubik's cube is sitting under the right side of my slimline ps2 helping to keep it off of the floor for heat reasons.

It's been there for a while.

Cool links though, man. I'd give 'em a try, but a 3D cube is hard enough for me.

Sudoku seems to just be looking for clues for a generic puzzle. It never loses its challenge, though.

. I've never been that enthused about rubik's cubes either. I've also recently gotten interested in sudoku and it seems like a more complex mathematical problem them doing a rubix. (The MxM sudoku matrix is an interesting problem from what I've seen.)

Maybe I have a horrible misconception, but people who are into rubik's cubes seem to talk way too much about rubik's cubes to people who have no interest in it. One of my friends emailed me and about twenty other people something about this and I replied "you could have MINUTES of fun after you learn this".

He sent us all a nine minute reply about how I was wrong. Whoop de fucking do.

But I enjoy Sudokus, and I'm sure Rubik's Cubes are fun. I'm just biased.

I am! My record is 52 seconds on a standard cube.
But I want to show you all something that can make you guys quake with fear!
First, there's Byrden's Java Cube site. He features several cubes that you can spend time on (go to "Big Boxes").
And for those of you who find the puzzles of our dimension to be no problem, the Superliminal team has created a Rubik's Hypercube!
It is a perfect analagy of a Rubik's Cube in four dimensions unfolded in three dimensions (it takes about forever to get used to). I haven't solved it yet, but I'm am very close!

Now, for the real reason I am here. The pure definition of Craziness! A man by the name of Roice Nelson has created a 5-Dimensional Hyper Rubik's Cube! You're a genius if you know how to look at it.
It is a perfect analogy of a 5 dimensions projected in 4D unfolded in 3D and projected again in 2D. It has 10 sides with 81 "hyper" stickers on each side.
Try out these puzzles and tell me what you think!
