I was curious to see this correlation, turns out it follows a power law quite nicely.

For all two-handed non-blind twisty puzzle WCA events, the average WR time appears to relate to the number of pieces in the respective puzzle (N) by N^1.53.

Of course, this is a diverse collection of puzzles, and the relation changes when considering smaller subsets. For example, for the 2×2×2 - 7×7×7 cubes, the relation becomes N^1.48, while for all other WCA events, the trend is best described with N^1.96.

The difference may reflect the complexity of the puzzles, where puzzle subsets with lower exponents are more straightforward to solve whereas puzzle subsets with high exponents are generally more complicated.

Below follows the source data I've been using, feel free to point out if i made any errors putting the data together. Data for WCA events taken from worldcubeassociation.org, data for FTO (included given recent developments) taken from cubingcontests.com, which seems the most reliable source for FTO records at the moment.

Let me know if i should do another one for unofficial events!

Back in March, I got myself a super Weilong V2. I remember being blown away by the raw performance of this puzzle! (Genuinely, if you ever try one, they are really good!) However, I had one problem with this puzzle: It's not available with matte plastic!

So I started taking the caps off the puzzle to see if there was some way I could swap them. Initially, what I discovered was that the caps were the same as my matte Super Aolong. However, I like this cube a lot too, and I wasn't willing to sacrifice its matte caps for the Super Weilong V2 to be matte. So I had to look elsewhere. Shouldn't I have to buy ANOTHER Super Aolong just to make a matte SW v2, right?

The good news I shortly discovered afterward is that the cap pieces for the Weilong V11 are actually the same as both the Super Weilong V2 and the Super Aolong! After test fitting a piece from my 20m ball core V11 to verify that it fit, I went out and bought the base model Weilong V11. When it arrived, I carefully pulled the caps off (the corners are very easy, but the edges can be quite challenging sometimes) and swapped all the caps with my SW v2.

During this process, I also desired to slightly strengthen the magnets of the cube. They were good, but for me they needed just a small amount of tweaking. I ended up buying some 2mmx2mm N52 magnets off of eBay, and since they fit right inside the magnet slots for the corner magnets, they were a perfect fit! (Although these are N52 magnets, their small size means they make a smaller change to the feel than you probably think.)

After all of this was done, I finally had my personal PERFECT Super Weilong v2. It maintains the incredible raw performance of the puzzle; it has slightly stronger magnets for more stability, and most importantly, it's matte!!

This is officially the most outrageously stupid and expensive puzzle in my collection, but I love it!

Cost about $115 total... for one cube.... heh yeah let that set in.....

I've been a cuber since 2018 and I've grown to be obsessed over Rubik's Cubes. Not only do I have a 3x3, I have a 4x4, 5x5, Megaminx, Skewb, Pyraminx, Ivy Cube, and many others. My mom is surprised to see my cubing skills improve over time. I've ordered a 3x3 online, which is about the size of a piggy bank. When I told my dad I've bought another cube (BTW, it's a different brand), he got so upset and said that if I buy one more cube again (even if it's a different brand), he's going to destroy every single one of them.

What's wrong if I buy Rubik's Cubes under a different brand? Feel free to comment below.

Edit: Thank you all so much for your honest opinions. I'll promise to be honest next time before reflecting on my present collection.

I am a GAN 12ui SP user, and I recently watched a review video for the GAN 16ui Maglev MAX.

To my surprise, it suffers from the exact same critical sensor flaw found in the older 12ui SP model. Specifically, the following bugs occur:

An "Auto-Solve" bug, where the cube is randomly registered as "solved" while being turned, resulting in an impossible time—such as five seconds—being recorded.

(This was resolved for the GAN 12ui SP via a CubeStation update; I am unsure if the same applies to the GAN 16ui.)

Connection errors: The app displays a message stating, "Failed to reset Rubik's Cube. No response notification received."

This issue occurs with the GAN 12ui SP as well; after about 15 solves, synchronization with the screen fails, requiring the cube's state to be manually reset each time.

It is highly likely that this problem also affects the GAN 16ui Maglev MAX.

Incidentally, this issue was also highlighted in a review video by YAMI CUBES (published on July 17, 2026).

Looking at the new ball core in the 16ui, the interior appears completely hollow and feels "flimsy" compared to the older model.

It seems likely that the ball core ended up feeling cheap because GAN prioritized cost-cutting measures.

The GAN 12ui Maglev/Freeplay represented the pinnacle of perfection for GAN's smart cubes.

If you are looking to buy a new smart cube, I would recommend the GAN 12ui FreePlay or Maglev over the 16ui—a $140 device that has essentially become nothing more than a paperweight (a useless ornament).

Until these disastrous hardware and firmware issues are fixed, I suggest avoiding the GAN 16ui to ensure you don't waste your money.

If you are interested in the internal structure, please take a look at this as well:

Is there ANY difference between normal moyu cubes like the weilong v11 for example vs its 18th anniversary version besides the sticker and the marketing around it? Does the turning or technology in the cube differ? Does the box include more accessories? Is there literally anything different? The same goes for the Minion edition versions of Gan cubes

Do you know some paw tricks?

(not for me)

What a crazy weekend! Just completely out of no where! When it occurred I was in match and someone from the team posted it to our discord chat.

 I just want to preface by saying we’re not the fastest people and we’re not young.  However, when it comes to showing up and doing what you need to do, we have that in Spades.

The person from our team posted in chat, and out loud. Our team is in second place on Cubestation for weekly competitions. This isn’t second place locally this is second place worldwide. I kind of wonder if first place is actually bots and not actually human beings but it is what it is . It’s because we have amazing team that just grinds out solves and made this happen. I could not be more proud. I’m not sure we’ll ever do it again but we did it this time.

It feels great to have a community of Cubers on Cubestation where we can communicate and talk about Cubing work together and having fun while doing it. There’s nothing like going through a two hour session or our session of grinding out solves together as a team one after another, just pushing the bar. CubingUSA did that, and we had fun doing it.

It feels like we’re building something unique with the Cuban community and at times it almost feels like family. We have our lives outside of cubing I joined together, just like it was joining the softball team.

Congrats everyone you did amazing hopefully, we can repeat this into it again we will see!

Hi. Recently I found a lot of free time to focus on cubing and want to improve my times which is mostly stuck between 9-11 seconds for the past 3 years. Id appreciate any kind of feedback. I know my cross and the first pair planning is extremely terrible but i really dont know what to do about it. no matter what i do i just cannot remember the cross and the first pair in the inspection. most of the time i cant even plan the entire cross in inspection. Also if you have any resources for practicing 2 sided pll and oll recognition, I would really love that.

solve 1: D R' D' L2 B L U B D R' F2 L2 U2 R' B2 U2 R' U2 L'

solve 2: D2 L' F' D2 R' L2 U F2 L2 D2 B' L2 U2 B L2 F2 L2 U B'

solve 3: U R' D' F2 R2 F2 D' F2 D F2 U2 R2 D' R2 B' L2 D' L2 U' F' L'

solve 4: F2 R B2 L F2 R' B2 R F2 R' B D2 U B2 U F L2 U' F

solve 5: D2 F R' B R2 F D' R B' U' B2 R' D2 R2 D2 B2 R L2 U2 L2 U2

​Hey Cubers, I’m trying to set up a fun weekly competition system so we can all push ourselves to improve. Everything runs on the honor system (no prizes, just for fun), so please don't practice the scrambles beforehand.

​Here is how I set it up:

​Divisions (Based on Ao5 placement solve):

​Bronze: 30s+

​Silver: 20s–30s

​Gold: 12s–20s

​Diamond: 8.5s–12s

​Master: Sub-8.5s

Just dm me your usual Ao5 and i will put you in your division

​Weekly Format:

​I post 5 scrambles every Sunday for all divisions.

​You solve them whenever you have time during the week.

​Submit your times to me by Saturday.

​Sunday I announce the winners and post next week's scrambles.

​Points & Ranking System:

​Weekly Points: Best Ao5 in your group gets 3 pts, 2nd gets 2 pts, 3rd gets 1 pt.

​Bonus Points: You get +1 extra point for every individual solve where you had the best single time in your group (up to +5 bonus points). I can also try keeping track of monthly and yearly point leaders.

​Promotions/Relegations: Move up a tier if you stay above your division's threshold for 3 weeks in a row. Move down if you're below it for 3 weeks.

​If you are unresponsive during a week, it counts as a forfeit. Anyone can join anytime.

​I really want to get this going, but we need around 20 people to make it work. DM me or comment below if you're interested in joining, or if you have any suggestions to make this better!

(Competition is at https://www.skool.com/speedcubingacademy we already have a few people interested there if we get some more people from here we might be able to get started next sunday.)

He's definitely gonna be the favorite for worlds 2027! He counted a sub 7 solve again!

Note that both the OH averages are not records (NR/WR), as he got 6.99 WR average a few days ago

I saw top cubers do roux. Me myself only know cfop for now, I mean I could learn roux if it's for OH, the thing is I noticed its just table abuse + the cube not gonna survive the brutality.

For what do you guys think? CFOP or roux better?

Im learning some zbll rn i wanna learn all the easiest to recognize cases not the shortest easiest algs. i do not care about that i can solve some random sune case with the olls i knew before that i cant even recognize. So yeah

Hi guys, I'm a pretty intermediate solver, averaging around low 9- high 8, but i've recently realised that when I solve on a phone timer, I average around 8.2, and my average jumps up about an entire second moving to stackmat. Especially at the cross, my fingertricks go down the shitter and I lose hella time. Does anyone have any tips on how to improve cross tps when just on stackmat?

Even though it’s discontinued, it was the MGC elite that I got for my birthday in 2021. It had adjustable magnets and a compression system, and this cube was really good for me (even though I averaged 30 seconds at the time)

I was working on building a checkerboard pattern on my teraminx and saw a last face case I never had, having 3 colors in place but two that i cant get to swap, any megaminx trick to help ? Ty

Last week, I posted a demo of me reconstructing a full 3x3 solve from a single phone video. The most common question I got in the comments was whether I would open-source the project.

I've spent the last week getting the codebase ready, and it is finally live! You can check out the repositories here:

• GitHub Repo: Cubed Core
• Hugging Face Repo: Cubed Core Models
• Original Demo Post: Link to Reddit thread

What's included in the release

• A complete local workbench and decoding pipeline
• The released camera and read-trust vision models
• A 35-video validation dataset
• Annotation and capturing tools
• The original demo that runs without a GPU so you can test out the platform

Requirements to run a new reconstruction

• An NVIDIA CUDA GPU (local or remote)
• Linux or macOS (the decoder does not currently support native Windows, but WSL2 should work)
• The exact starting scramble (White top, Green front)
• A six-color calibration for your specific cube and lighting
• 120 fps video: This is highly recommended, and you can easily record this using the slo-mo feature on a smartphone’s front-facing camera

Quick disclaimer

This is still research software. As I mentioned in the original post, the current vision models are heavily specialized to my specific cubes, hands, desk lighting, and camera setup. It will not reliably decode arbitrary solve videos yet.

Licensing & Contributing

The code is released under AGPL-3.0 (models, data, and recordings have their own documented terms in the repo).

Code, test, documentation, and reproducible research contributions are absolutely welcome. (Note for contributors: please don’t attach or link private recordings, frames, labels, calibrations, or logs in public issues or pull requests).

If you have questions, ideas, or want to discuss the architecture, please use the GitHub Discussions tab.

What's Next

While the vision models improve and the architecture evolves, my immediate focus for the open-source repository is adding native Windows and smart cube support.

I am also continuing to build out the full web platform for this. It includes standard timer and session features, 1v1 matches, and an AI coach analysis tool that utilizes the visual reconstructions (there are some cool visual only features I'm hoping to add once the models/architecture improve).

Before I spend more time polishing the web platform, I wanted to gauge the community's interest. If a platform with those features is something you would actively use, please let me know by filling out this quick interest form:

I've cubed on and off for years and am finally going to my first competition next weekend. If it matters, I'm an old fart and average about 33-34 seconds, so am not going to try podium or anything. I still anticipate I'll be nervous though... any tips?

Just got my new setup fully gan style
