Should Rubik's brand cubes be prohibited for BLD?

[daniel0731ex]

if it has to have either stickers or tiles, what about Dazzler with modified corner?

 

[Tomk]

I think it would be reasonable to modify the rules to state that it's ok for one center piece to have some sort of logo indention on a single center cap. As long as there is a fair playing field, so anyone can choose to have that kind of center cap if they wish, then I don't see where the problem would be.

But a blindfold solve is meant to be that you memorise first, doesn't having something you can feel have the same effect as letting the judge tell you, "oh that stickers white BTW"?

This discussion are going nowhere.

It only raises more and more questions from non-BLD solver. :fp

One thing for sure, the WCA Board are too busy to respond to this thread.

You should be able to keep your cube orientated if you are doing BLD solves. One centre cap shouldn't really make that much difference. Also, if you need a cap to tell you what colour a side is it's not like you're going to win any competitions.

I fail to see how this raises any questions at all. The rules are VERY clear and I suggest that you read them again.

Also, Dianshengs with only painted faces are not allowed for competition under the current regulations.

I do not speak for the board, I'm a delegate, but the regulations really speak for themselves on this subject.

You fail to see that I DO NOT have any problem in understanding WCA Regulation.

The regulations are very clear on this subject. If you can distinguish a cubie/face by feel then the cube are invalid for BLD. End of discussion. This rule actually applies to all puzzles and all events, not just BLD.

Yes, the regulation is VERY CLEAR on its own (de jure). But how about in reality (de facto)? MANY people uses puzzles with markings/indented logo for official competitions, including myself.

As a delegate, did you ever prohibited any competitor who bring indented puzzle to the competition?

What's the point of the regulation if many people are ignoring it?

THAT is the discussion and it's still far from end.

I agree with Chuck. If you interpret the rules very strictly, a very large percentage of BLD solves (and regular solves, for that matter) were done on illegal cubes. Fortunately, except for multi (where I have many stickered cubes), all of my 3x3x3 BLD solves were done on cubes with tiles.

I think it's pretty silly, though. I think we should change the rules to clearly allow this case, since it's clear it doesn't give any significant advantage. As we get bigger as an organization, we need to refine our rules to become as precise as possible. At least, that's my opinion. If we just make it clear that rules 3j and 3l go together (making it clear that a logo is okay even if it's raised and can be felt), then the rules will clearly allow an ordinary storebought Rubik's, and there will be no problem.

Chuck, have you started a thread on the WCA forum about this? I don't check that forum as often as I probably should, so I haven't looked in a while. Truth is, the WCA doesn't have a responsibility to look for stuff like this on this forum - if you're really concerned about it, you should probably bring it up there instead. That's really the proper place for a discussion like this, not this forum.

I already did

"3l) Cube puzzles must have at most one logo. For Rubik's Cube or bigger cube puzzles the logo must be placed on one of the centre pieces."

Having a logo is not a problem, but if the centre cap with the logo on it feels physically different, it's illegal. Does the centre cap have indents under the sticker?

How about giant air bubbles?

Ah, I didn't think of that. I'm really sorry.

Chris, thank you.

I agree with this too.
Thank you, Mike.
