The World Record Corner Twist that Changed Speed Cubes Forever

[@RandomShorts7861]

In my Maths class, we are doing probability and the rubiks cube came up because of the absurd amount of combinations there are to scramble it (43 quintillion), so my teacher said hell show us a video explaining it. Our next lesson, I walk in to see J Perm on our projector with my whole class watching on as you explained why there are so many combinations. So thank you for educating us all!

[@PandaFan2443]

Would you mind telling me how you did that calculation? I tried it myself and got a figure much higher. However, I think it might be because I treated every square the same, disregarding that some cannot move because they are center pieces and also disregarding that certain colors can never be paired together.

[@RandomShorts7861]

@@PandaFan2443 I would try my best to explain it but I think it would be better if you watch J Perm's video about it because he explained it really well and cut it up into easy to understand steps. Thanks for asking tho

Thank you Feliks for twisting a corner on a WR solve so that we could demand better cubes. And congrats J Perm for being better than Feliks confirmed.

[@JPerm]

Its confirmed

[@nasdfigol]

@@JPerm yep

[@teomoktemokte5756]

Yea

[@Macrotrophy-mq3wh]

LOL

[@Pure_Vanilla_C00kie]

i twisted a corner on the rubiks brand XD (if you offset your cube 45 degrees then you can twist a corner)

[@koendos3]

A possible reason the corner on Feliks’ solve might have twisted, it his thumb. His thumb seems to be quite highly located on the F-face. So when he did his final U’, his thumb might have been blocking him to make the full turn. Yet, he forced the turn anyways, and twisted the corner.

[@Geebinator]

That makes sense

[@JPerm]

I guess it doesn't look that way to me, but maybe he has big thumbs. Edit: tried it on my aolong, and i hurt my thumb a lot and it still won't twist. Maybe his cube was a lot looser

[@Geebinator]

@@JPerm does the aolong have adjustable tightness from centerpieces?

[@nasdfigol]

@@Geebinator probably tbh

[@djaziztube]

@@JPerm I notice you switch from analyzing the twisted corner W G R to the opposite corner that was near his index W B R. I agree with @Koendos3 it looks like his left index might have pushed the W G R corner over the tip of his left thumb. The center slice also looks like it's rotated a few degrees in M' direction which when I try and turn the top layer on my cube it just locks up if the W G R corner has to climb over 1/3 of the G center. Maybe the two forces combined did the trick? I don't have this OG cube so there's really no chance I could replicate it but the physics of twisting a corner that way also seems super unlucky.

The way Valk reacts at 8:52 is so good, his initial reaction is dismay that he lost the record but he _immediately_ hides it and claps for Feliks

[@haikumists1115]

It's such a good, professional reaction. There's nothing wrong with feeling dismay that you lost, it's a natural human reaction. But what you do afterwards is what matters, and he chose good sportsmanship.

Ive seen that video so many and never picked up on that. I was always distracted with how "happy" Feliks got 😂😂

[@suyashtiwari4698]

I love how he's explaining the most basic stuff that you can understand by common sense, but still make it calming and entertaining enough that we never get bored on it for 10 minutes, also because there isn't a 1000 cubes he talking about and he isn't making his voice sound over excited forcefully, this video feels better than a few videos he has posted recently.

[@uncubeable]

What? I've been a cuber for 3 years now and I've never realized that the design of the corners is actually so complex and smart🙉

[@SJohnTrombley]

It's pretty crazy how far the technology has come. I was still using my guhong V2 until like 2021 when I finally bought a rs3 m. The guhong still has cubesmith stickers on it. I miss cubesmith.

[@brands2131]

My Guhong v2 still has a Lubix sticker on it. Also I had v-cubes of sizes 5x5 and 7x7 which had the textured titles from cubesmith (which I no longer have).

[@mrmidnight32]

I don’t know speed solving but looking at the video and given the pace, it’s not just misaligned, it looks like he has torque on the cube because if you look at the (our right) his left side of the cube in the video 3:28 is floating and the front side has gaps showing it’s under decent amount of torque probably by an aggressive grip which I’m sure most do when going for these records at these speeds.

[@dosgos]

Fascinating design evolution. The cube companies have really optimised cube engineering; there is a lot of thought and effort behind these. Great video.

[@MasterOkojo]

I actually do remember that corner twist happening to Felix. It was about when I started speed cubing. It's crazy how much cube design has changed since.

[@merylsmith5305]

Very recently got back into cubing after 9 years. It blows my mind how much cube designs have changed over that time - if you had asked me back then, I would have said there was certainly some room for improvement, but assumed that we were pretty near a plateau of diminishing returns. I dug out my old collection for my students to use - they were outrighted shocked to hear that my ZhanChi was considered one of the best cubes back then. Honestly compared to even some super budget stuff nowdays, its practically unusable.

[@-..--...-5-.212.4]

Jperm Is probably the best cube explainer in the world, He is very super calm and always stay to the point of the video, This video is splendid!!!

[@Pixelman0]

If you play mk8, you should do a colab with this small youtube named shortcat

[@BTapia0524]

Yeah, that will be intense

[@Fynimus]

🤣🤣🤣

[@Nothinghahahahahahah]

Actually, you can see his thumb rubbing on the corner while he did a turn. His thumb was in the middle of the corner piece (don't know how to explain using words) and so the thumb rubbed against the piece but the turn still was forced through which led to it twisting. And the corner even turns the way that makes sense to the idea listed above

[@רפאל-ב]

2:50 it pushed against his thumb

[@lc846.]

At 2:44 I saw that his thumb was touching the corner so maybe that was the reason the corner twisted

[@yololinsken3045]

[@zZeimos]

0:44 gave me the chills

[@ari90i]

I think the reason Feliks got the corner twist is because the corner hit his left hand thumb which could have provided a clockwise torque on the bottom part of the corner where the white and green parts connect

[@JPerm]

That's possible! it didn't look like that to me, but it could be. Also i just tried it, and my hands really hurt, yet no corner twist. maybe his cube was looser.

[@ari90i]

@@JPerm Yeah i tried it with one of my really loose cubes and I couldn't get the corner to twist, but honestly I don't see any other way it would have happened lol

[@ScrapFatherScrapSon]

It’s crazy that normal cameras can’t slow down the frames enough to see the cube terming without blurring. We need some speed covers to reach out to the Slomo guys so that they can capture a Rubiks cube getting sold in super slow motion.

[@ps.2]

Oh I think a lot of cameras _could_ record at higher framerate, but even a default 30fps setting is good enough to reconstruct an 11tps solve, so nobody really sees the need to override their flat thing to set a higher framerate for routine filming.

when i was first learning how to solve a rubiks cube on some off-brand 3x3 I literally tried for hours and hours and I couldn't do the last step cuz there was a corner twist. I just decided that i'd call it quits and I re-assembled the cube but then my friend came over and scrambled it so I tried solving it again and that was what kickstarted my cubing hobby

[@Neptune084]

j perm is the type of guy to upload a vid about world record 9 days before the world record was beaten

[@LunarForte]

This story was so tragic! The AoLong v1 was my main at the time and it was basically wiped off the earth after this solve. I got the v2 when it came out, but I hated it. It felt like a completely different and slower cube. I ended up panic-buying a couple more v1's, but everyone did the same. I was only able to get white ones. This started a couple year run where I mained all white plastic cubes just because I didn't want to give up my v1. It's great that, in the long run, this helped cube designs improve by a longshot, but I still remember the panic when I felt that v2. I still have all of those AoLongs and, needless to say, they feel nowhere near as good as even budget cubes you can get today. That really was a wild time in cubing.

[@chloedevereaux1801]

when he rotates the top, the left side was rotated upwards with his left thumb..... you can see it almost happen in your slo mo at 3:25 ..

[@stealthyshadow567]

Speedcubing pre 2016 or so was such a wild time compared to what it is today. The standard measure of a “good cube” was corner twists per 100 solves, the expectation was you would get corner twists often and you just had to cry about it. Stickerless cubes weren’t competition legal. Using Vaseline sandpaper and WD40 on cubes was standard procedure (the plastic deteriorating was solved by simply buying another cube) literally everyone used the same cube (guhong, zanchi, aolong, etc) also vcube was like one of the genuinely better options for a speed cube, bonus points for being available in Barnes and noble’s.

I believe the corner was twisted because when he turned the top layer, his left thumb was right in front of the corner. As it came into contact with his finger near the bottom part of the piece, the movement of the whole layer tried to move it while pushing on his finger, making it turn

[@penguinisuslol6468]
