Turn corner

[TobiasDaneels]

I've got a regulationsquestion.

What happens when you accidently turn a corner (only a corner) during a solve?

My cube is quite loose and once in a while it happens, without me even noticing it. Then when I stop the timer, off course the cube isn't tottaly solved.

Is it plus 2? Or DNF?

Thanks

Check the regs? Is it solved?

Dan D, incidentally, informed me that it's illegal to correct y twisting the corner in place. I wonder how many judges know that...

It's no longer illegal to have a cube where this can happen, right? (Arnaud recently said it wasn't illegal anymore, but it once was.) So is the legal way to fix this that you remove an edge, fix the corner, then put the edge back in (before stopping the timer, of course)? What exactly is required to make it a legal fix when this happens?

Oh, and what if (again, before stopping the timer) you twisted another corner in place the opposite direction, then performed a cw/ccw algorithm that corrected them both - would that be a legal fix? (I would think it would be, but I'm just wondering. It might be faster than popping the edge.)

Isn't there some rule saying that it is illegal to have a cube where there are extra movements possible (such as rotating a single corner) than normally intended?

 

[Mike Hughey]

Well, there's this rule:
3h) No modifications are allowed that enhance the basic concept of a puzzle. Some examples of enhancing the basic concept are: new moves are possible, normal moves are impossible, more pieces are visible, colours on the backside of the puzzle are visible, moves are done automatically, more or other solved states.

So I guess, yes. But if that rule applies here, then that would mean a large percentage of competition cubes are illegal, right? Especially OH cubes? (I've always kept my cubes tight enough that this isn't possible, but I've been contemplating loosening them a bit after Joshua Satterfield pointed out that my cube is pretty stiff for a speed cube.) And actually, all of the cheap Chinese MegaMinxes would also be illegal then, since it's easy on all of them to twist corners in place.

I have this happen as well on my DIY cubes(I was stupid enough to sueprglue the centers so now I can't fix them) but I've never had this problem in competition. I believe, though, that it is considered a DNF if you was to finish a solve and end up with one misoriented corner because I once saw a guy whose center peices flew all over the place as he set it down in San Diego 2007 and the judge gave him a DNF for the solve time. So it might be the same case with the corners because the cube would be essentially solved it is just that the piece is turned wrong. As for what would make physically fixing the corner a legal fix, I don't know. I would assume you should be allowed to fix it as long as you don't stop the timer.

The solution: Force an "accidental" POP. Then you can fix it Just kidding, hehe.

 

[cubes]

It would prolly be A DNF

 

[MistArts]

5b3) If after repairing the puzzle, but still during the solve, the competitor notices that the puzzle is unsolvable, he/she may disassemble and assemble max. 3 pieces to make the puzzle solvable again.


So...you have to fix it during the solve

If you stop the timer with it being flipped i would prolly be a DNF

 

[Lucas Garron]

It would prolly be A DNF

If "prolly" means "definitely."

If you stop the timer with it being flipped i would prolly be a DNF

You would?

Lucas you beat me to it.

So according to rule 5b3, simply twisting the corner wouldn't work, because you would need to disassemble the edge, take out the corner, put the corner back in the right way, and pop the edge back in?

 

[pcharles93]

Yeah, you need to take the edge out, otherwise, you could just manually flip the corners after getting the cross instead of full OLL.

 

[TobiasDaneels]

Thanks for the reactions.

Need? That would necessitate "must" where the regs use "can."
But let's assume 5b3 covers it.

 

[Lofty]

Can I pull the corner out and then put it back in correctly?

 

[pcharles93]

I think you can because it's not against the rule that says you can't have a puzzle that can do moves others can't i.e. twisting corners in place. If you can just yank it out and push it back in, I think you're OK.
