There is an interesting discussion happening on the speedsolving.com forum, and I wanted to bring it to the attention of the board because it does bring up an interesting point of discussion at the very least. I will quote the original thread from speedsolving.com by Chuck. Also, here is the link to the current thread: http://www.speedsolving.com/forum/showt ... post277938 [quote:3kjga5oa]Hi all, Few days ago, a new Indonesian cuber named Sandy Ardianto was asking a question on Indonesian online speedcubing forum: [i:3kjga5oa]"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.."[/i:3kjga5oa] 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 [b:3kjga5oa]must not have any textures, markings,[/b:3kjga5oa] elevated pieces, damages, or other differences that [b:3kjga5oa]distinguish one piece from a similar piece.[/b:3kjga5oa] 3m) All puzzle and sticker brands are allowed, [b:3kjga5oa]as long as the puzzles comply with the other WCA regulations.[/b:3kjga5oa] So, to prevent a BLD competitor get benefit from it, should Rubik's brand cubes be prohibited for BLD? :confused:[/quote:3kjga5oa]

I will agree that it's ironic that a Rubiks brand DIY cube are invalid for competition use, but I don't see what we need to discuss. Markings on a cube makes it invalid for BLD regardless of brand.
