Hi everyone i (the greek nr holder)wil hopefully going to athens open this Will be at read for everyone who is coming also, becuase this is sponsorde by vcube are you allowed to use ss cubes (Sebastián plzzz answer )
3m) All brands of puzzles and puzzle parts are permitted, as long as the puzzles comply with all WCA Regulations.
So yes, you are allowed to use SS cubes. The V-Cube guys probably won't like it, but they can't forbid it, at least if they want their comp to be official.
