roice writes "Rubik's junkies and puzzlers will be interested in this software rendered four-dimensional analog of Rubik's Cube. With over 1.75E120 possible combinations, it's a mind bender. Free versions are available for both Windows and Linux, and they even publish their source code for download. Solving it will get your name listed in their Hall Of Fame, and there is also a running competition for the most efficient solution. To help get you started, you can check out a solution algorithm based on techniques used to solve the popular three-dimensional version."

Heck with solving it. There are some things that just aren't worth solving. Now where can I find a software rendered four dimensional analog of a hammer and nail?

Is this actualy 4D ? (4, Interesting)

Forge (2456) | more than 10 years ago | (#6147754)

I don't know. It looks like a more complex 3D version that's just real togh to build with plastic.

Maybe it's because I read some quack's claim that the 4th dimension was time. In which case a 4D rubics cube would solve itself over time or be onsolvable because it rescrambled while you were trying to solve.

The 4th dimension is whatever you define it as. There's no "true" 4th dimension. Einstein had the idea that time could be treated in a fashion similar to that of the spatial dimensions, and so, in his work, he defined the 4th dimension as the temporal dimension.
However, for this program's purposes, it's assumed that we're talking about the 4th *spatial* dimension. You can (kinda) visualize it if you think of the progression of first 3 dimensions: a line (1st d) can be rotated 90 degrees to itself to form a square (2nd d) which can be rotated 90 degrees to itself to form a cube (3rd d). The 4th dimension is thus hypothesized as the space defined by a cube rotated 90 degrees to itself.
(Granted, I'm no mathematician, so if someone has a better understanding, please correct me.)

I met a girl online once who was a wiz at the rubik's cube. When we met in real life she had her rubiks cube with her and she could solve it in less than a minute. Her hands were a blur. I was very impressed, but this 4D rubik's cube blows my mind! Being red-green color blind would make this a difficult if not impossible task for me to complete. Good luck to anyone else with enough free time to try it though.

That has got to be one of the sweetest ideas for legos I've seen in a long time. I also think it's a HUGE waste of time and effort, but I guess if you've got a itch, scratch it.

Maybe somebody subjected you to one of my favorite old tricks. Take one corner off of a solved cube and rotate it so that the colors don't match the rest of the cube. Reassemble in this orientation. Presto: unsolveable cube.

Kinda funny -- I've inadvertently subjected myself to this same trick as a child. It always took so long to scramble the thing, it was easier to take it apart and put it back together in random order. Little did I realize there was a very good chance of creating an unsolvable cube.

Furthermore, I went so far as to buy a "how to solve the rubik's cube" book. Followed every goddamn step in that thing, and was pissed when it wasn't working. Eventually I tried it on my sibling's and it worked, and I came to the conclusion that mine was defective. Not sure how long it took me to figure out how mine became defective, but the blame was fully mine. :)

Gotta say, trying to solve an unsolveable puzzle sure kept me busy. It may have gotten my frustration tolerance up high enough that I can stand to debug those really nasty programs....

A regular computer would solve it in less than 10 seconds. Really a messy scramble of the 4D cube took only 6 seconds to solve. And it wasn't even backtracking.

Anonymous Coward | more than 10 years ago | (#6147659)

Neat game. It's been around a while. I've been able to solve 7 random twists. The first thing you have to do is start with a ordered cube and see what happens when you twist it different ways. Not consistently, though. The trick is to figure out what the last move probably was, reverse it, the one before it, reverse that, and so on. After 3 random twists, you might be able to make a bad guess and recover from it. After 7, one wrong turn is a good reason for starting over. Never was able to solve a regular 3d rubiks cube puzzle though.

Just a word of warning to the foolish and brave. Before you tackle the 4^4 hypercube, make sure you buy an ergonomic mouse and mousepad.

mice/trackballs do I need to install to solve this thing? Alternatively, can I use mouse and keyboard? Ah heck I might as well be playing Counter-strike.

Not complete (1)

Actually this is not a complete 4D rubik's cube. A hypercube had 8 sides, each of which are cubes, you can only see seven at any time in this program. The eigth one is there though; when you rotate a side, you will see cubies being rotated in from off-screen, they just don't show it. But since they don't show it, you cannot actually rotate that face. That would be like having regular 3D rubik's cube and not be able to turn the white face.

Still I love this program. I'm a big fan of rubik's cubes and of geometry of higher dimensions.

Not quite. It's like having a physical 3D rubik's cube and not being able to see all 6 faces at the same time. You can however turn a physical cube around so you can see the hidden face. It's a similar idea in this one. The way to see the hidden "face" is given in the FAQ:

Q: I can turn a real cube around so that I can see the hidden faces, can
I do something similar to see the invisible eighth "face"?
A: Yes. If you hold down the control key and click either mouse button
on any part of a "face", the puzzle will "rotate" in 4D until that "face"
is in the center. That "rotation" will bring the invisible face into the
same position as the one you clicked on. The "face" on the opposite side
of the puzzle will "rotate" out until it turns inside-out and becomes the
invisible "face". This "turning inside-out" motion is very typical of 4D
"rotations". Notice that control-clicking either mouse button on the
central "face" does nothing because it's already in the center.

So I don't mind confessing that I regularly solve the 3D cube in under two minutes. If I'm lucky, and corners align nicely, then under ninety seconds. Like most humans, I find it rather difficult to visualize 4D objects. I can't imagine however that it would take more than a few days to adapt to the 4D cube. But where will the madness end? Will some depraved geek (me) be screaming for someone to code a 17D cube? A 139D cube? Hyperdimensional cubes are an abomination! If it can't be expressed in reality, then it is a sin.

Posted AC cause I'm drunk as hell.

Well it's not news, and it's not even close to new, but it sure is nerdy :)

Did anyone not have a cube?

"Hey stupid - are you too dumb to know there are 4 different simultaneous 24 hour days within a single rotation of Earth? Greenwich 1 day is a lie. 4 quadrants = 4 corners, and 4 different directions. Each Earth corner rotates own separate 24 hour day. Infinite days is stupidity. Most math is erroneous. You are educated stupid."

Each twist of this puzzle is wholly owned by us and any person who says otherwise will be subject to a rather large lawsuit.

I ask the Slashdot editors to remove this "story" from their website, so that they comply with SCO regulations.

Thank you for your co-operation.

"fully functional"? (-1, Redundant)

> MagicCube4D is a fully functional four-dimensional analog of Rubik's cube.

WOW! He's managed to somehow manipulate 4-space from 3-space! Nobel Prize in physics, here he comes!

I was never able to get the hang of the cube, but this this guy [middlebury.edu] sure did. His web site has more info.. but the video [middlebury.edu] is the coolest part. FYI need quicktime to watch the video.

Finally, a cool article! (0, Flamebait)

Wow, today I'm impressed with Slashdot because they really are running a "news for nerds" story... And how!

Seriously, I sometimes complain about goofs and stupid decisions made by the editors, but I'm a fair person, so ... way to recognize a cool story!
