Should Rubik's brand cubes be prohibited for BLD?

[Chuck]

Hi all,

Few days ago, a new Indonesian cuber named Sandy Ardianto was asking a question on Indonesian online speedcubing forum:

"Ada yg tau yg jual centercaps Rubiks ga? Yg ada tulisan rubiknya, lumayan buat bld wkt M2, bisa tau lg shooting genap ato ganjil.. hehe.."

He asked where he can buy a Rubik's center cap which have Rubik's marking on it. Why? Because he thought that it would help him to know odd-even condition for M slice's edges when he was doing BLD using M2!!! :fp

Of course other members got mad at him and told him that it's cheating and illegal. But this made us realized that Rubik's brand cube are not comply with these WCA Regulation article:

3j) Puzzles must be clean and must not have any textures, markings, elevated pieces, damages, or other differences that distinguish one piece from a similar piece.

3m) All puzzle and sticker brands are allowed, as long as the puzzles comply with the other WCA regulations.

So, to prevent a BLD competitor get benefit from it, should Rubik's brand cubes be prohibited for BLD? :confused:

Cubesmith and Cube4You stickers also have stickers that can show direction.

anyone who uses feeling the center cap to determine if he is m2 clearly would not know what he/she is doing and so would not get a good time so aint matta

Yes, I'm very agree with you.

But it's still very disturbing to know that there is a cube brand that doesn't comply with WCA Regulation, and it's RUBIK'S.

Well wouldn't ALL cubes with logo's be illegal? I don't really understand your post.

Nope. In one of the Rubik's brand center pieces, there is an indended picture of the Rubik's logo.

Oh, nevermind, that makes more sense then.

"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?

Yes. Using tiles would solve this problem though.

Really? That sucks.
Even my A3 and C4Y DIY have logo-imprinted caps. Oddly enough, I can't feel them ._. I'm using normal stickers

 

[mcciff2112]

The C4Y speedcubes have an indented logo in one of the center caps as well.

Edit: Hyprul9-ty2 beat me to it..

They normally come with 7 centre caps. Only one has the marking.

I've ordered over 10 c4u DIY's and all of them have come with only 6 caps.

 

[qazefth]

Yeah, I only got 6 caps. And I can feel the logo. :S

Makes me wonder if having no stickers on the white side of a white-cube would still be useable.

no, they made us sticker the white side on our white 7x7 at worlds, after the first solve...

3e) Twisty puzzles must either have coloured stickers or coloured tiles.

i suggest we should make the judge aware of the puzzle that someone use for BLD, so the scramble judges test the puzzle, if the puzzle have "defect", so the scramble judge can tell the judges that stand beside the competitor that the puzzle have a mark or whatever, and be sure to look if there's any suspicious movement from the competitor =)

 

[Chuck]

So, it still remain a question. :confused:

Should those cubes be prohibited?
Or maybe some changes on the WCA articles?

What's the deal of having a different looking piece if you are blindfolded?.
If it feels differently when you touch it, that's another story.
