Hi Cubers
I recently solved the cube blindfolded. My mom fells it’s simple . So that’s why I want to tell her exactly how many people (%) can solve the Rubik’s cube blindfolded. I also want to make a video above my journey of learning in YouTube @DZSRUBIKSCUBE
Thank you
 
It is really hard to guess this number, but here is a statistic that might be useful: It appears that there are less than 10,000 people who have solved a cube blindfolded in an official WCA competition. I'm not sure of the exact number because I don't have a recent WCA database dump downloaded, and the statistics page has been limited due to the size of the database getting too big. But I have found that Hideaki Tomoyori (友寄英哲) has gotten a 3x3x3 BLD solve in competition (at over 80 years of age!) in 13 minutes and 55 seconds, and he is ranked 7865 in the world. So I would guess the total number solving in an official WCA competition is likely somewhere around 8000.

It is hard to guess what percentage of people who have solved a cube blindfolded have done so officially. I would guess it might actually be a fairly high percentage, since anyone with the dedication to try to solve a cube blindfolded is likely to want to prove it in competition. But what I'm considering a high percentage here is still far less than 100% - if I had to guess, I might guess that 10% of people who have solved a cube blindfolded have done so in official competition?

With that assumption, it seems reasonable to guess that perhaps 100,000 people have solved a cube blindfolded. But that is certainly a very rough guess, and could potentially be off by a couple of orders of magnitude.

I find this answer convincing.

10^5 people who have done 3BLD successfully (timed or untimed, official or unofficial) sounds right!

Tell your mom that she couldn't even rearrange the stickers blindfolded
 
I would like to see blind CFOP as an event. You must use CFOP and your solution must be reconstructed afterwards to prove it.

That seems like a bad idea. Not everyone can reconstruct their solves, they just solve. It also seems like it could be easily cheated.

With CFOP blind you have to inspect very long, when I did it, i inspected for half an hour. I promise you you'll remember the solution after thinking about it for half an hour.

Don't multi and FMC take a whole hour? I'm not saying CFOP BLD should be an event, but that is not a very good reason to keep it away from the WCA.

The whole point of FMC is that it’s not a timed event(you can’t get a world record because you do it faster) and MBLD is about how much not how fast as well. Also, it seems limited. Only being able to use CFOP. What makes a solve CFOP anyway? Don’t you think over time what counts as CFOP will shift into something completely different from where it started.

Yes MBLD is also about time. If it weren't, I would have a tied NR. I don't.

Now that is a good reason why CFOP BLD shouldn't be an event (except for the last part, CFOP is just CFOP, if a different method appears, it will get a new name). What is CFOP anyway? Does ZBLL count? Couldn't you use roux and say you just didn't finish the cross and made it in a weird way together with last layer, after finishing F2L? That is why it shouldn't be an event.


If I remember correctly, speedBLD used to be an event. You could inspect for as long as you wanted, and you had to do a speedsolve afterwards, but blindfolded. The result would not include memo. You could use BLD methods, but that is slower so that's why methods like CFOP were used. It was not obligatory to use CFOP though. It was quickly removed, probably mainly because of unpredictable time management.

I knew that you were good at bld but didn't realize you had nr2 or 24/25 for multi bld.
 
speedBLD sounds perfect, but for organizational reasons inspection would have to be limited to something like 15-20 minutes.
