I'm officially at that age where I get flannels, socks and Rubik's Cubes as Christmas gifts.

Spent a few hours learning the algorithms and now I can solve mine in about 5-10 minutes. It's incredibly satisfying.

Now I'm going down a rabbit hole to increase my speed. I wonder if I can achieve a sub 1 minute solve time with enough practice...

Way back as a kid I could always do 2 sides but no more. My bros could do it all if you gave him enough time.

But supposedly you only need to know about 20 tricks and you can do it fast.

As a kid I got the rubiks globe which was impossible. None of us could do it.
 
I bought one recently to reach the threshold for free shipping. I only remember playing with one once as a kid, but it's quite fun to twist and rotate the different parts. I've only been able to line up one of the sides completely. Should probably watch a tutorial sometime.

This is the one that helped me understand the logic and algorithms. Other tutorials confused me lol

Back when I worked at reddit (so like 2012ish), the artist there used to make every employee a little avatar (this was back when there were like only 10 employees though), and this was the one that was made for me lol.

I own about 100 of them, so I better know how lol. Shoutouts to my F2L bros.

Just got this one for Christmas. The sides are thermal-sensitive, so you can only see the colors by warming the cube with your hands. https://a.co/d/7f100VS

Also if you’re trying to get to sub-1, grab a nice GAN at some point. The Maglev series is phenomenal (though a bit pricey). https://www.gancube.com/products/gan15-maglev-3x3-advanced-magnetic-speed-cube

Just timed my latest solve after posting this thread - 5m36s. That was with some mistakes, so once I eliminate that I should be under 5m. How people solve these things in 10 seconds blows my mind.

Are magnetic cubes better than spring ones? My daughter gave me a regular Rubik's branded cube and the turns catch a lot which slows me down. I'm not ready to invest in a super pricey cube yet, but I was looking at this one as an upgrade. Thoughts?

Yeah the magnetic ones are incredible. GAN is definitely the highest quality, but you can get knock-off GANs on aliexpress and stuff that are still pretty great.

The key to getting sub-1 is learning F2L, or “[solving the] First 2 Layers [at the same time]”. Tons of good tutorials online, but it does take a while to learn. Not as long as just learning how to solve the cube, though.

Thanks. I’ll look up a guide on F2L. I’ve seen the acronym but didn’t know what it meant.

I've been solving for around 20 years now. My focus has been on developing methods and techniques for solving. I recommend checking out the various existing methods versus being funneled in a specific direction by YouTube. Examples being Roux, ZZ, Petrus, APB, and CFOP. Below is my website that contains my developments.

There is a very active and dedicated community behind these things. Pretty cool seeing so much enthusiasm for these things.

Never understood the point of memorizing a few tricks to solve a rubicks cube...amounts to pulling off a magic trick in order to impress those unaware of the algorithms? Also when you understand the logic, isn't it the same shit every time, just trying to improve fluidity/effiency?

Isn't the Rubik's cube essentially a non-abelian subgroup of the S_48 symmetric group? So, it shouldn't be NP complete and therefore be solvable by a deterministic algorithm in polynomial time. So I guess I can solve it. Would need to buy one and think about it first, though.

Yeah. There is essentially an algorithm to follow to solve a Rubic's Cube.

It is kind of neat.

I did solve the Rubic's Magic. That one is actually easier. There is a definite procedure to follow.

I did when I had one back in the day. I also graduated to 4 by 4 one. It’s been years so probably would take me a while today.

Yeah this was me as well back then. I'd get frustrated as I couldn't figure out what to do if you had an off color or two in the middle or sides of one section. And rearranging them only made things worse.

So the best way to win was to remove the stickers and reapply them.

I can do a 3x3. I did my first without an algorithm. Took me forever. Second time took me around 30 minutes then I looked up some methods and it was much faster. Can’t imagine one of the bigger ones.
 
I have a really crummy mini one that is pretty difficult to move around. Tried a couple of times while watching TV or whatever but never solved it. OP said he learned some algorithms and still found it satisfying. Is that the consensus? That looking it up doesn't rob you of the satisfaction? Doesn't seem likely with my personality.

no. I never had the interest to look up a tutorial, and I haven't owned one since I was like 12 I think...

maybe I still got it lying around somewhere tho

Nah, I don't feel robbed because I looked up what to do and how to do it. You still have to remember the steps and then apply the moves correctly depending on where pieces are located. It's engaging each time.

I still make plenty of mistakes too, which are fun to solve in reverse. Then there's the whole speed factor. I did a 3m40s solve earlier. Since then I've been doing ~5m ones, so there's room for improvement on my end.

I'm kinda shocked at how popular these things are. This is just the first row on Amazon. That's a lot of cubes.

I bought one a while back but best I could do was matching one side. Tossed it in a drawer and never tried it again. Stresses me out.

I did it once, many years ago and took me about 2 weeks. I'm very proud of my self because I did it without help of any kind. I didn't watch any kind of tutorial.

Ok. Did my first FTL. I get how to do it in theory but in practice it’s a disaster. Just need more repetition. I can tell this is gonna be a YUGE level up. To quote LectureMaster LectureMaster , MY MAN!

Awww yeeaaahhh!

I’m in the 3-5 minute group.
I learnt about 3-4 years ago and I wanted to learn some new algorithms to do it faster but I just can’t be bothered.

My kid got me a Rubix Cube Phantom for Christmas which is supposed to be black and as you use it it changes to the colours using what I assume is the mood ring tech.
Unfortunately we live somewhere hot as balls and unless I put it in the fridge it’s always coloured.

For some reason this reminded me of when I was a young shit and used to hustle people at bars and conventions with my Rubik’s cube.

At bars, I would lightly mix the cube in a specific way, then hold it in a particular way, and then bet people at the bar that could solve it in one move. It was technically four moves, but it was one swift motion so it looked like one turn, and boom, solved. Got a handful of free drinks that way lol.

But for the other hustle… I used to go to gaming and anime conventions when I was younger (used to sell games as a vendor), and without fail, if I was playing around with my scrambled Rubik’s cube in public, someone would eventually come up to me and say “hey, can I have a go?” and want to solve it.

I’d always respond with “okay, but these things are impossible, there’s no way you can solve it.” And of course they’d be like “oh yeah I can! Give it here!” I’d be like “Hah, I’ll bet you five bucks you can’t solve it. And no peeling the stickers or breaking it apart!” And they’d always agree, so I’d hand over the cube.

Little did they know, I’d have taken a piece out of the cube, rotated it, and put it back… which made the cube completely unsolvable lol.

They’d get to the of the solve, but it wouldn’t work, and I’d watch them struggle. They’d eventually give the cube back, defeated, saying something like “well your cube isn’t working right” or something. And I’d be like “hey man, no excuses, pay up!” And to add insult to injury, while talking, I’d slight-of-hand the piece back in the correct orientation when they weren’t looking, then proceed to mix and solve the cube in front of them. And I’d be like “see? The cube works fine, I knew you couldn’t solve it!”

Lol I was such a shithead in my early 20s. 😂

I got one of those for Christmas too! They’re super cool, but I have the opposite problem where it’s so cold here that it’s hard to see the colors lol.

There’s this other really cool new Rubik’s cube that uses lenticular stickers, so each sticker has two colors depending on what angle you view it at. And each side of the completed cube is viewed at a random angle, so it’s not consistent.

It’s a really fun an aggravating solve. It took me a few days to eventually solve it, and I had to meticulously try and write down which “primary” color I thought each sticker was. I’ve heard it can actually be solved two different ways, but I was only able to solve it back to the original form. And I’m too scared to mixed it back up now 😂

I have gone out of my way to not completely learn it. Same with chess. I think it might end up being less fun if I do. At least that's what happened to me with competitive Pokemon

Any tips for F2L? Any pieces I should focus on first? I can do it consistently now but it takes me 5-10 minutes lol

Never mind. It just clicked! If the colors on top are different the middle piece needs to be on the right. If they're the same color the middle piece needs to be at the back.

Aww yeah! And really, it’s just down to practice and pattern recognition. Once you get down to like 1-2 minute solves (you’re closer to that than you think), it’s about shaving off precious seconds by trying to look ahead at your next move, right before or even while you’re doing your current one, and just trying to reduce the number of rotations of the cube overall.

Then it’s just about recognizing which patterns call for which algorithm variants, which just takes time. But you get better every time you solve the cube, so that’ll happen really without you even trying.

You’re gonna get sub-1 before you know it! Especially when that new cube arrives ;)
