I remember trying to reassemble a 4x4 with my friend.
It was the longest evening of my life.
I just spilled tea on my mgc 4x4. With cleaning lubing and reassambling, it took around 3 hours.(My first time reassambling a 4x4)
I have yet to reassemble my 4x4 and I really don't want to
@@soosawesome1151 It helps to not do it alone
the same thing happened to me can't wait to try a 6x6
I once disassembled my 6x6 thinking a can reassemble it but it was hard it took me like 5 hours with my sister

Why did you let your 6x6 watch this video?
I always wondered why the outer layers of large cubes were bigger and why the inside of my 4x4 was so weird! Thank you for the info!
I initially got into cubing around the time the V-cube 6 came out, but I lost interest in the hobby for around ten years after that. It's crazy coming back to it now and seeing how the technology has progressed.
I'm glad there was a small clip from Code Bullet, I love that guys channel!
Good channel but a little excessive on the curses
@@Frost-rx4ch well its normal for a coder that has gone insane
@@Frost-rx4ch I agree
you mean CB
I wish Code Bullet would not shove so many details under the rug in every video. I also wish he'd actually make something which the title describes.
As an aside, the point at 4:10 also explains why all the world record cubes for a while now have been odd-layered.
Because making an even-layered cube necessitates that you have a working design for an odd-layered cube one degree higher. Why make a 16x16 when it requires that you know how to make a 17x17?
There are also people competing to create the largest even layer cubes. While a bigger number is alluring hiding those center layer in higher order cubes get's increasingly difficult. So it's a feat worth of accolade in it's own right.
So does that mean i need to learn 5x5 before i can do 4x4..
Do it just to flex. If someone snatches the record from you by picking the low-hanging odd fruit just above you then everyone will know they compromised and don't deserve the record.
@@x520x1314x no. If you learn a 5x5 you still have parity issues on the 4x4. However, if you learn the 4x4 you can probably solve the 5x5
@@silevol you only need to learn one additional algorithm to solve 5x5 after 4x4. The other way around requires 2 additional algorithms for parity that is avoidable on 5x5.

When you mentioned the imposibility of having a proportional 6x6 and 7x7 I remembered one of The Cubing Historian videos. It showed a proportional 7x7 made before the v-cube one, but it had a very different mechanism
Yeah, the pieces flexes to allow more room. Its insane.

I’ve always wondered why bigger cubes had weird pixel sizes. I thought it was so they’d be downward compatible to other cubes, like a 6x6 to be used as a 3x3 without damaging your eyes squinting. Or a 4x4 to a 2x2, a 4x4 also could be synced to 3x3 logic.

J Perm, Thank you so much for explaining this. I remember when Rubik's incorporated cane out and said that the 6x6x6 was practically impossible, and the 7x7x7 was theoretically impossible, so quit asking us. These cubes won't be coming out any time soon. And we waited a quarter of a century!
There was another wait between the V-Cube 7x7x7 and the Shengshou 8x8x8, but not as long. This is hard for current cubers to understand when it feels like there is a new larger cube every year.
My only complaint about this excellent video is you didn't mention V-Cube's original solution, pillowing. It was Shengshou that made the outside layers larger. And I believe it was Shengshou that had the spherical core.
Anyway, thanks for this excellent video!
The V cube he showed had no pillowing?
Shengshou More Like Shing Shong
I'm glad that you explained how the mechanics work, and how it was previously impossible, because I struggle to even understand the crazy mechanics behind stuff like the 1x2x3 and other odd shaped cubes.
The 1x2x3 has a similar . mechanism as the 2x2 and 3x3, because the corners and edges are held by the centers, unlike the Squares, the corners on the 1x2x3, 3x3x1, and 2x2x3 are just edges, but the leg and foot are on the Edges instead of the Middle

I'm staying away from even numbered cubes because they're a pain to magnetise. At the same time it's annoying to see that a 12x12 is much cheaper than a 13x13, which according to your video makes no logical sense :)
I had an early 4x4 and it was not like yours inside at all. Inside there was a ball with 3 tee shaped tracks in which the edges ran and the corners ran on the edges. there was some clever shenanigans with blocks in the the tracks that made the ball maintain the proper orientation and not get twisted about one axis relative to the cubes as you demonstrated with the 6x6. It was vey difficult to disassemble and reassemble.
This video and video of disassembling a 4x4 led me to a q if it is possible to create a 6x6 with a sphere core as the one in a rubik's 4x4, but more commonly used in a 2x2. And I already started working on it but first I want to replicate the 2x2 then the 4x4 and then finally try to aply the same sphere core to a 6x6. Now I don't think it's possible but I would love to know and if I get around to do so I'll have an answer. Another crazy idea is to make the corner and edge pieces lock to the surrounding center pieces when it turns. Or make a bigger 6x6 with thin but strong leg. Or magnets with high chance of popping out.
great video! I thoroughly enjoyed learning about cube mechanisms.
That's a super interesting breakdown of the different sized cubes and their parts, thanks!

@@u1zha interesting. I’d still say trying to engineer it on your own is harder than solving on your own but I’m pretty sure no one makes a 15x15x15 on their own so you could be correct.

Yay, an upload from our master j perm. The one and only.
Tell me about it! No matter how hard I try and how many hours I put in, it's practically impossible to build a fully proportional 5x5x3 Rubik's cube! Even using illegal techniques such as an an edge piece folding at 90 degree angle. But even if I accomplish that, if both of the center edge pieces on the 5x5 face are aligned adjacently vertically on a 5x3 face, it cuts the folding edge piece off completely!!
Man, this video is amazing. I never understood, because I never thought about, why people made big cubes with big corners pieces. Just thought "probably a weird design choice". Now I get it.

My 3x3 and 2x2 are so hard for me to take apart, I can’t take them apart, but I had no trouble taking apart Delilah’s spinner, except for the corner pieces. Delilah was able to do it as well, and it wasn’t put together like the other cubes because it’s like a 1x3 or something so it was able to be user as a fidget spinner which is why I call it this. I also got a slider from McDonald’s which you can turn like a normal cube but it has a missing white piece (it’s meant to have a missing white piece) so it can slide too. It has 6 sides, 3 pieces on each side except white, with a missing piece. White looks like this when solved:

I have a V-Cube 7, 5, 4 and 2 - the V-Cube 5 is my usually go to cube if I just feel like solving a cube. The even number cubes have a parity that can kick in requiring a very complex move which I've never been able to keep memorized for any length of time, while odd number cubes don't have it. I can solve the 7 just fine, but the 5 takes less time and as mentioned above doesn't contain the possibility of the parity problem.

I was always very baffled of how a Rubik cubes worked since you needed to turn every piece in every way, it was only recently that I found out.

@@HaiYou_Studiosofficial maybe the first 4x4 didn't have the 5x5 mechanism
i love how the 22x22 pop is the most replayed
Neat! The internal design of these larger cubes is way more complicated than I would have expected.
The original 4x4x4 Rubik's Revenge design uses a spherical core, where the center pieces have long thin and somewhat fragile legs to slide in slots in the spherical core. There are no hidden middle layers on the Revenge. The original 5x5x5 Professor's cube design was the first to use a cube in a cube core. That led to the later Eastsheen 4x4x4 design also using a 5x5x5 like cube in a cube core. The Wikipedia article includes images of Revenge and Eastsheen internals.
1:09
Evan, my man I forgot all about him.
Ay, Code Bullet vid is here :D
Thanks J Perm
Does anyone else remember getting excited when V Cubes came out in 2008 and we were all excited because it could outperform the eastsheen 5x5? And does anyone else remember gluing pins to the centers of their 6x6 so it wouldn't lock up? And you also had to pay to get them shipped from Greece...
Jperm. After 7 times losing . I succeeded in reducing 4x4 to 2x2 .At 8th try at last I got parity and then I did the parity alg and it swapped some centers around as shown in your video . After that when I solved the centers and it was reduced to a 2x2 . I got inspired by your video.
I have to mention that although the 6x6x6 has to have larger corners and edges, the V-cube 6 hides that fact very well. It seems like V-cube made their corners larger by the smallest margin possible to make the cube seem like it's proportional. The difference is even less noticeable on the pillowed version. It's interesting that they would make this choice based on aesthetics.
Had to dig out my cube and check because I never noticed the size difference before, it is a very small difference.
I was wondering about that. He mentioned how impractical it is for a proportionate 6x6 but we have the v cube 6. That was so confusing till I found your comment
You should a video on how many solved positions there are on a 4x4(the center pieces can be in different places)
Well, if you only consider one center, then there should be 24 (4!) different ways to arrange it, since any center piece can go anywhere. If you take into account all of the centers, then, there are 24 possibilites for each of them, meaning there are 24^6 (191,102,976) different solved states.
The interesting thing about this is that the same logic applies to even bigger cubes, since they're all sort of laid out in "classes" like this: (here's an 8x8 for example)
| A | B | C | D | F | A |
| F | G | H | J | G | B |
| D | J | K | K | H | C |
| C | H | K | K | J | D |
| B | G | J | H | G | F |
| A | F | D | C | B | A |
Any two pieces in the same "Class" can be swapped without unsolving the cube, and notice! There are always 4 of each class. Since the number of pieces on a cube of size 2n is equal to (2n - 2)^2, that means that the number of classes is equal to ((2n - 2)^2)/4. (You can do a bit of simplification to get the formula k = (n - 1)^2, where k is the number of piece classes)
Therefore, for any cube of size 2n, there are 24^(6 * (n-1)^2) different solved states, which is interesting because it means the number of solved states is always equal to a power of 24.
@Kshitiz Pokhrel Craaap you're right, I realized that a while ago. Not really sure how the math for that one would work out.
Amazing!!
Oh, when I saw this video I assumed you meant solving it. Still turned out to be entertaining though!

J perm video makes my day
Love that inside red of that 4 by 4
I remember when I was a little girl and I got the V-cube 6 as a Jól present. This video really sent me on a nostalgia trip. I still have my V-cube 6 and 7 in my closet somewhere and I should definitely take them out and fool around with them again
I remember seeing the v cube 6 and thinking
“Now this is the future of cubing”
plot twist: 1x1 cube is a 2x2 with side layers hidden!
Very good observation
Thanks for this video, now I know why my six-by - yes, an older V-Cube - gets stuck so much, and how to fix it. That's going to vastly reduce the headache factor of this thing.
Considering the V Cube 6 has outer layers the same width as inner layers and it works just fine, I'm pretty sure you don't mean that a 6x6 *has to be* designed with wider outer layers (since a fully functional one could be designed with uniform width layers), but that having wider outer layers decreases the chance of a corner piece breaking and thus is preferred for modern 6x6s.
It’s an incredibly small difference, but the V-cube 6 does have bigger outer layers. You can just barely see.
I thought I remembered the original V6 and V7 being pillowed in order to solve the corner problem, am I misremembering? Either way I think it would be worth noting that pillowing is one option instead of making the outermost layers thicker.
Thanks, I always wondered why 6+ cubes had longer edges!
This guy is really help full
I looked at the thumbnail and counted the area of the cube to see what was wrong with the cube. Didn’t see anything wrong. After watching the vid it made sense.

AMAZING VIDEO
About the corner piece needing to be extra large in order for a 6x6 to actually work... later in the video you show a 6x6 where the corners and edges are all the same size as the rest of the pieces. How does that design overcome the corner problem?
Yeah, we can see one right at 5:19
The 6x6 is the crossover point. There is just about enough space for the mechanism to fit, but it won't be as durable. Therefore V Cube decided that it had to be all of the same size since that was the standard back then, but that caused issues, so these days every 6x6 has big corners. The V Cube doesn't really overcome the corner problem, it just is barely possible with a 6x6.
The stickers are square but there is still a thicker border outside the stickers which has the extra thickness of outer layer
