I would love to have a real blind event where also inspection is without eyes. With the Rubik's Touch Cube or similar cubes. That would bring something really new to the community and it would bring blind persons an event where they can really compare with seeing people.

I also like the idea of a 4x4 FMC or even 5x5 since I imagine lots of different ways of approaching it that would be interesting.

I don't think there are any shapes that are very many moves from cubes, so I don't think it will be any harder than squan.
You don't have to think whether there are shapes that are very many moves from cubeshape, because someone has already computed the distance distribution. A few percent of states (rare, but not especially unlikely) are 25 moves or further away from cube, with the maximum possible distance being 28 moves.

(Additional complication: on the square-1, the scrambler actually solves CSP, not just cubeshape. The analogue of CSP on a Curvy Copter would be much more complicated, and may increase the average/maximum distance a lot.)

Something I thought about is the shape argument using squan. While it probably wouldn’t harder to deal with than squan, it still invariably is more complicated to scramble. Both will change shape, but with squan, the shape is changed only by turning the U/D layers and slicing. However, the jumbling on the CC can by done on many sides so I do think it is more complicated and not a perfect comparison, albeit close. I think it may be difficult to do the scrambling images cleanly. I do believe Sion had a pretty good idea about the +/- for doing jumbling moves though!

Thanks, that post is fantastic. I didn't realize the extent to which this puzzle could jumble (I thought there would be at most 1000 shapes).

Of course it's gonna be more complicated to scramble, the jumbling has far more possibilities. It would be fine for competitions if the scrambles were 60 moves or even more, since the competitors will mostly be taking far longer to solve this puzzle than a squan.

Yeah. I brought that up because I was proposing using non humbling initially until a good system is in place for jumbling. People then compared that to cubeshspe only scrambles which i wanted to show isn’t a perfect analogy because the CC has many more axis that can turn and change shape.

a kilominx would be a cool event,but i can't see the event list expanding for a long time due to it being hard to fit in 18 events anyway
if feet does actually get removed though,something like kilominx could replace that

It would also see a huge development in hardware as right now there's only 2 or 3 kilo minx's out there

I assume the reason you say mirror blocks is logistically impossible is because of inadvertent turning when bringing the cube to the competitor - difficulty placing the cube on the table without messing up the scramble (like square-1 without the inserts)?

Bruh why would you want mirror bld? stupid idea
Mirror BLD, without inspection. Really not such a stupid idea. Plenty of other events are worse, including some official ones. And I personally love this one because it would even the playing field for actual blind competitors, like the couple we have occasionally post on this forum. But I do recognize the logistical difficulty.

isnt re-scramble just inverse speedbld?

anyway for things not in the template, my personal bias wants jings pyraminx to replace both pyraminx and skewb.

a lot of the suggestions on the tier list would be really repetitive imo
stuff like 8x8 and 9x9 and 6BLD just add time and there would be no use to adding more than 1 cuboid
if people really like unnoficial events,add them to a comp you host or do them add home and try to get UWR
the bigger the community around an event,the more chance it has of being official

rescramble is basically BLD but without a blindfold
everybody good at 3BLD would be good at rescramble due to it being easiest to do using BLD methods

Master kilominx and gigaminx will be the same, since they take a long time to solve, at least longer than solving a 7x7.Hardware are not well developed. However, adding more than 1 cuboid may not always make an event useless to be added. For example, Master Pyraminx, do not take a long time to solve. QiYi and Sheng Shou have made speed master pyraminx, so the hardware are not bad.

the best people at master kilominx take around 4 minutes,so i guess it would be too long
master pyraminx seems interesting,but the worry is that it could get trivial quickly
