Magic

[Ewks]

Hi,
I was playing around with my rubik's magic and one of the strings broke. Can I still use it? How does it affect in how the puzzle works? And if it's safe to use it, is it competition legal?
Thanks

If it's only one? then it's not a problem at all, it just make the pussle a little sloppier and easier to break more. Most Magic's I used lacks a string or even a whole bunch. It works fine as long as there is at least one in each loop (normaly two in each but some hardcore ppl like me and Erik J are using triple strings to make it more stable).

It is not safe to use it, it will break more soon, but that's Magic's, they break sooner or later = it is not safe to use any Magic

It is competition legal.

I remember seeing somewhere a comment that a non-double-strung Magic was not competition legal. But I don't see anything about that in the rules, so I'm assuming that was a faulty comment. I have a Magic and Master Magic that are both missing quite a few strings - only about 3 strings are doubled on the Magic and about 5 on the Master Magic. Does anyone know where the idea came from that they needed to be double-strung?

Also, I have a Magic and Master Magic that are strung backwards and/or upside down. Are they competition legal, or not? Is there some definitive place that shows the correct way? I think I know the correct orientation (based on the majority of videos out there), but I'm not positive.

While we're on the subject of rules, I also thought I remembered once seeing that if you could twist a corner in place on a 3x3x3 cube, it was competition-illegal. But again, I don't see anything in the rules about that. Does anyone know about this?

I've also heard that, but I don't see that realistically being illegal. Almost any DIY that isn't uncomfortably tight (and I'm sure any DIY used for OH) is loose enough to twist a corner in place.

The 3x3x3 corner-twist was in the rules, but it is not anymore

Basically the rules are now:
No adjustments that make the puzzle easier/different to solve from an original one.
Filing/lubing/modding is allowed to make the puzzle move better/faster, but not if it makes the puzzle easier.

That means:
Magics can be strung both ways because they were sold both ways.
Magics cannot be strung in a way that would allow for moves that aren't normally possible
Missing strings are not a problem (unless they would somehow allow moves that weren't possible, but I don't think that is possible)
You cannot change the prints on the magic so the solution would become different

It also means:
Only 1 logo
No transparant cubes
No bad stickers (important for blindfolded)

Thank you, Arnaud - that was VERY helpful!
