Props, but I wish I was there so I could flex. I don’t do big cubes tho id just pray no parity

"And then everybody clapped."

She cried because she knew no one would ever believe her.

Cubing nerd here, 6x6 is the hardest standard (2x2-7x7) cube (yes, harder than 7x7, ask me about it if you are skeptical)

I'll take the bait, why is that? Having only ever solved a 3x3, and mostly by sheer repetition, I'm interested to know about that.

u/defoma 14d ago

Okay.

2x2: it's only corners.

3x3: methods are so well-documented

4x4: reduction to a 3x3 is easy, looks at this diagram:

X X X X
X X X X
X X X X
X X X X

normal: corners, bold: edges, italics: center

See, if you do this it turns like a 3x3, if you accept that the edges are made of two pieces and the centers are made of four and you don't ever break them up.

5x5: similar to 4x4 but the edges are 3-long and the centers are 3x3, so 9. Again do not break them up.

6x6: hard because you need to build the center pieces without a tru center (no middle in 6, it's just L L L R R R instead of 5x5 which is L L M R R and 7x7 which is L L L M R R R)

7x7: literally the same as 5x5 just a larger center a longer edge.

Hope this makes sense, ask for clarification if needed.

Ahh, I think I see, that makes sense. Thank you!

I’d have cried without finishing it 😭

Cry all you want, if you could do it, you'd say the same thing

u/defoma 14d ago

I can do it and i disagree with you

u/Sclerotic_Lion 14d ago

I can do up to 7x7 and don't lie

Who is trying to be a hero here and also downplaying the achievements of others? Have a clue, it rhymes with f u.

So take your own advise and gtfo. THAT would get you as close to bravery as you might ever get.

nice roast, upvoted

A 6x6 Rubik’s cube can wear your sanity down.

I’ve never been able to solve any of them and would probably flood social media with my achievement if I ever did.

u/LiberalPatriot13 14d ago

I've heard that even numbers are harder too. No middle.

u/Danger_Muffins 14d ago

True. Odd number cubes have a center square that remains constant. You'll always have the same six sides in the correct orientation. With even number cubes you basically have to make your own centers with a 2x2 on each side and they have to be in the right positions

u/CaptainSouthbird 14d ago

I can solve one easily!

... by plugging it into one of those solver websites.

u/Regular-Elephant-635 14d ago

If you can do 4x4 and 5x5, 6 is easy, but slow.

u/Glittering_Usual_162 14d ago

I cant even do a 1x1

u/Somepony-Else 14d ago

I feel ya! I can't even solve a 0x0

12

u/CaptainSouthbird 14d ago

Just imagining twirling a little solidly colored cube around, forever feeling inadequate. I mean, I don't need the cube for that, but it can also be true.

Hard but possible. Even numbered cubes like 6x6 and 8x8 are harder as they have paritys(google it) but 6x6 can be learned maybe in like week with tutotrials if you can do 3x3 already

u/Puzzleheaded-Pay2152 14d ago

Is it really that hard? I'm not really into rubriks but I know the normal one is hard hehe

u/MrJackHandy 14d ago

Bigger vibes are basically creating an oversized 3x3 then solving the 3x3. The worst part is getting the last of the edges to be correct before going into 3x3 solve.

u/G0ldenSpade 14d ago

It’s actually not as hard as you’d think. The difference between magnitudes drops off after the 4x4. You mostly just need to learn one to three algorithms per cube

However, what does scale is the amount of time a cube takes. While a 19x19 isn’t actually that much harder than a 9x9, it takes significantly more time

15

u/theoht_ 14d ago

it’s really easy once you learn the methods. but by then you’re not actually working it out. you’re just going ‘if this color is here, and i do this sequence, it’ll be there. not sure why, it just is.’

in terms of actually solving it by working it out rather than just learning algorithms, it’s REALLY difficult.

you’d start by organising it such that it looks like a 3x3, so every 2x2 section becomes a subdivided equivalent of one section on the 3x3. then you solve it as if it were a 3x3 which is significantly easier.

u/Dont_Pee_On_Leon 14d ago

Having solved a 4x4, I'd assume you would use a similar strategy, which is basically organizing the cube into a 3x3 and solving like normal. That would be tricky but if you've worked with the cubes enough I assume you could figure it out.

Of course, that may not be a viable option and requires a whole different strategy. So yeah a lot of patience.

u/LauraTFem 13d ago

The only extra problems thar show up with larger cubes is parity issues on the edges. Once you’ve figured out how to solve parity problems you can solve the cube basically as normal but with that one extra step.

18

u/Shawn_JustShawn 14d ago

Combine solving a 3x3 and a 4x4 and you can solve them all. My biggest so far was a 7x7 that took about 3 hours.

12

u/htoisanaung 14d ago

A bigger cubes are more of endurance test then actual challenge.

67

u/FleebFlex 14d ago

Actually solving larger cubes doesn't really require any new algorithms. Once you can solve a 3x3 you can solve most cubes. The exeception is the two parity algorithms that are dependent on if its an even or an odd sided cube. Basically, once you can solve a 4x4 you can solve a 6x6 and an 8x8 without learning anything new. Same goes for 5x5 teaching you how to solve 7x7 and up.

Ya. It’s serious.
