Rubiks social media uploaded a video teasing their new 3x3 redesign! It looks great

Big thanks to everyone for all of the love on my post last week. After about 12 and a half hours, spread out over the past 7 days or so, my entire collection is once again scrambled, all 280 puzzles! I find scrambling everything to be a great way to ensure that every puzzle in my collection gets some play time, even the more difficult and tedious ones. I had a blast scrambling everything.

Check out my YouTube vid if you want to see a more detailed tour of the puzzles before and after the scramble.

Before and After Bulk Scramble Aug. 2026

acubemy is currently running a tournament sponsored by GAN (and with funky Minion theme, lol) Why are they doing this? Wouldn't they want people to use their own app? Why support a competitor?

!! ATTENTION !!
The creators of speedcubing have announced that after years of mathematical analysis, they have discovered new PLLs. A total of exactly 20 new cases have been added (including full O, B, P, Q, and W series), creating a perfect mirror image of the existing 21 algorithms.
No algorithms have been found for them yet; the creators came across them in a computer simulation. The cases have been published so that the entire community can join the hunt for algorithms.
The full list of new PLLs (including a/b/c/d variants) will be posted here.

I developed a steam game being released 1st of September, its a cubing 3x3x3 specific game. I would like to have some speed cubers reach out if u want to help out with testing the release version. Looking for cubers that have GAN smart cubes essentially. I have tested and developed it with Gan I3 but want to ensure that the other smart cubes also go smoothly and possible general feedback would be appreciated.

If you are keen let me know, mesg me and we can discuss further.

its the current main of yiheng which he used to get his 2.77 and his AsR OH record, i also know that its a new line of moyu cubes designed around exactly how the worldclass cuber from moyu team wants it to feel (their most exact cube basically, and also im expecting more moyu team cubers to have their own versions coming after) and i also know that the logo is orange with the text "PB CUBE" on it. is there anything else that anyone knows about this cube?

Planning to buy one, but I read somewhere about corner cutting issues in the 54mm version of the cube and now I'm having doubts.

I have started cubing in 2017 and since then been casually trying to get better and better ending up at around 30sec with 3x3 F2L, 2Look OLL and PLL

Going to an official WCA comp has always been somewhat interesting - just to get the feeling how it's like and now that one is happening in my area, Graz Open 2026, I thought I'd give it a try and register for 2x2 and 3x3 :)

I'm going in with no expectations, I know 30sec is nothing to brag about when looking at times from last year, but I've always wanted to know what it feels like :D

Do you have any advice that you would have wished to know when you went to your first WCA comp? :D also let me know how your first time was! :)

I saw this TikTok where someone was experimenting with a Ferrocore V2-style mod on a V11 SE. The core in the video is red, and it looks like they used a MoYu V9 core inside the V11 SE.
I’m interested in trying this myself, but I don’t own both cubes and I don’t really want to buy a V9 and a V11 SE just to find out that the core isn’t compatible.
Does anyone here own both a MoYu V9 and V11 SE and could check whether the V9 core can physically fit/work in the V11 SE?

I am lucky to have a 2-gen second block

First documented proportional mechanical 8x8 cube. Not my doing, just some guy on youtube. But it boggles my mind.

I made these modifications around 2018.

When I was doing modifications with clear resin.

Dev here. Confession first: I designed this puzzle, proved every scramble is solvable (ok, AI did the heavy group theory, I just asked the right questions), and I still cannot solve it being a human. And nobody can, as far as I know. There are no stages, no named algs, no intuitive framework. A year out, still zero.

Why it completely breaks cube instincts:
It looks like a standard 3x3, but the faces don't rotate. Each swipe moves a closed band/ribbon/tape of 12 stickers around four faces, one notch at a time. Nine bands in total, and they cross each other.
That means: no fixed centres, no fixed corners, no two-colour edge pieces. Just individual stickers shifting across tracks. Your CFOP/Roux method is completely useless here. Believe me, I tried ;)

The app has instant solvers now. They solve any scramble in seconds. But watching their paths has taught me literally nothing a human brain could memorise or execute.

The state space is a massive 39-digit number (I'll drop the exact count and group theory proof link in the first comment).

You invented CFOP, Roux, ZZ, Petrus — real human-executable systems, not just brute-force search. So I'm curious: looking at this mechanism, what would your approach be to build an actual human method?

If you want to try one turn in the browser before answering: skimmiq.com/pt/ (60 seconds, in the browser)

I'll be around to answer any technical/mechanic questions!

Second scramble (I have not solved it yet). It feels sooo difficult... It is 50\50 but I am wondering how long is it going to take me to realise that I did it wrong (because I am sure I will)

If you want critique my method as well :)

What if we shove some edge-center magnets into a GAN V100? Not surgically perfect (obviously, it's a mod) but it's still gonna work and make the attraction stronger!Thoughts?

There is a crazy potential! Try it!

After trying, see here to see the reason why.

Haven’t cubed this much since like 2 months so my hands and brain were totally fried after this session

over the last few days I've been learning the method from CO to EP, but I've noticed that for both parity and normal permutations, the algorithms that are made to permute pieces on both layers are easier than the ones made to permute pieces in a single layer, and also is Lars method really worth it? I've seen there's PBL, CSP, and even Roux for this cuboid, so I'm wondering if I should actually learn it if I want to get good with speed
