WCA Documents: Updated January 1, 2013

The competitor was notified, so they chose to use the music stand when they registered

The statement was added a few days after the registration started.
Most of the current registrants did not see it.

Besides, I don't think it is good that the organizer takes away competitors' freedom to choose...
If that is allowed, all competitors in this competition cannot choose inserting a paper.
Please compare the following statement with B4c3):

If requested by the organizer/judge beforehand, the competitor must place the puzzle behind a suitable object (e.g. a music stand, the surface of the table) by himself during the blindfolded phase.
​
which is essentially equal to the current regulation in Kansai Open 2013.

5b3b would be redundant, because if you put everything back in the exact spot in came from, you would always have a solvable puzzle

It is perfectly possible to put a popped edge piece back in the same spot, but flipped. :cool:


Anyway,
I started to re-write article 5, trying to address some of the holes and ambiguous wordings that have been pointed out. Then, in doing so, I stumbled upon even more questions. Here is the start, followed by my thoughts.


5a) The following are considered puzzle defects: popped pieces, pieces twisted in place, and detached screws/caps/stickers.

5b) If a puzzle defect occurs during an attempt, the competitor may choose either to repair the defect and continue the attempt, or to stop the attempt.
5b1) Tools and/or pieces of other puzzles must not be used to repair the original puzzle. Penalty: disqualification of the attempt (DNF).
5b2) Permitted repairs:
5b2a) If any pieces have fallen out of the puzzle or moved out of place, the competitor may place them back on the puzzle in any open gaps. No fully attached pieces may be intentionally moved into a different position during this process.
5b2b) If, as a result of a previous repair, the competitor finds the puzzle to be unsolvable, he may disassemble and reassemble a maximum of 4 pieces to make the puzzle solvable.
5b2c) If the puzzle is unsolvable, and can be made solvable by rotating a single corner piece, the competitor may make the puzzle solvable by twisting any corner in place without disassembling the puzzle.
5b3) If a puzzle defect occurs during a blindfolded event, any repairs must be performed blindfolded. Penalty: disqualification of the attempt (DNF).
5b4) ?? [see below]

5c) If a competitor has a puzzle defect, this does not give him the right to an extra attempt.


In 5a....how the hell do screws get detached in the middle of a solve?

I removed the following: the current 5b2 (any repair must not give competitor any advantage), and the "he must only repair the defective pieces" clause in 5b1, as they seem too ambiguous. I honestly can't figure out what kind of specifics 5b2 would be referring to that weren't addressed elsewhere anyway, and it was pointed out above that that clause in 5b1 is problematic too. The way I understand it, it should suffice to make the Permitted Repairs section specific enough so as to make it clear what is and isn't legal.

In the current 5b3a (my 5b2a), what exactly is meant by "or moved out of place"? What kind of situation is this referring to? I kept it here assuming there was a reason for it to be there, I'm just not sure what that is.

In the current 5b4, what is the purpose of: "a puzzle defect must be repaired during the attempt"? The wording in 5b (either repair the defect and continue the attempt, or stop the attempt) already addresses the fact that defects must be repaired during the attempt; this clause feels entirely redundant.

For the purpose of handling the current 5b5, I have to ask: what are all the cases and their desired results? Is the following correct as far as the writers' intentions, and is there anything missing?
edge or corner popped or twisted: DNF
No more than one bigcube wing per orbit popped: Solved
Single center cap popped: Solved
2+ center caps popped: DNF
1+ bigcube centers of the same color popped: Solved
2+ bigcube centers of the same type but different colors popped: DNF
Square-1 piece popped: DNF?


That is all for now, until some of the above questions have been addressed.
 
I think someone who messes this up doesn't possess rudimentary intelligence:

And if you do let him mess that up, you allow him to move stuff around. Which you're not allowing in other cases, so that would be inconsistent.

I'd say you're again implying this should be considered solved, not DNF.

I think it depends. On a Sq-1 (at least mine) you can only pop a piece back where the gap in the rail is, so you'd have to move the gap to the where the gap in the rail is. (As this is part of the basic concept of the puzzle, I don't think this violates any rule). Of the 8 possible ways to rotate the layer (finger can be placed on all 4 corners, each clockwise or anticlockwise), only 2 of them preserve the gap in its place. So, depending on how you rotate the layer to get to the gap in the rail. As Vincent says, we should assume the possibilities as if the repair is done by someone who does not have a clue of the basic concept of the puzzle and doesn't see the colours, so he just pops it back where he sees a gap.

Of course, you can argue that someone who doesn't know the basic concept of the puzzle won't know that he needs to move the gap to the gap in the rail in order to pop the piece back in. In that case, he would just try to pop the piece back in where gap is. The worst that can happen is that he fails to pop it back in and give up: DNF.
 
The statement was added a few days after the registration started.

I have a feeling that this is a misunderstanding between me and the organiser, probably my fault. As far as I understood the organisers request, he wanted to ask the registrants for their agreement during the registration process and not demand their agreement in order to be able to register.

I will contact the organiser to clear things up.

I was thinking about my proposed writing for 5b5 and it is not perfect. Because the reg says "If parts of the puzzle are still defective...", and a twisted piece is also a deffect, so this case doesn't need reassembling.

Maybe we could have this part split in 2:

5b5) If any piece is twisted in place at the end of the solve, the result is a DNF.

5b6) If any piece is not fully attached/placed at the end of the solve, the result is recorded as the worst state obtainable by reassembling the puzzle.
(Dont' see 5B3*)

*There's no need to see any regulation here, you just reassemble the cube putting the pieces back in where they fit.
 
I like the idea that it would now be allowed to have pops (piece out of puzzle) at the end of the solve. The way time is measured motivates people to drop the cube on the table and if pieces come out at that moment while it is still clear that the puzzle was solved it should be counted as solved in my opinion. This used to be the case for centercaps (non-functional pieces) and I like that this would be the case for pieces as well. Of course that makes it necessary to define "clear that the puzzle is solved".

Having 1 centercap be ok and 2 centercaps a DNF goes against my feeling of fairness.
And having the idea of you COULD put it back wrong, so it is a DNF is just silly. We give +2 for a turn that is missing and we don't question if the competitor would have done that turn in the right direction. Of course we can't just call a whole exploded cube solved because you could put it back correctly but the old rules were fine

Why not make it like this (not official wording, somebody needs to lawyerize this!):
* You cannot cause defects on purpose except for the purpose of fixing a previous defect. This is for the judge to decide.
* If it is unclear if the puzzle is solved at the end of the solve it is DNF
* If functional pieces are out of the puzzle after the end of the solve it will be a +2.
* If the puzzle can be solved with 1 move after the end of the solve it is a +2
 
1.Why was article 6 removed(i think awards and prizes)? The regs look a bit weird with no number 6

2. just clarifying, Suppose my 5x5 is solved with some(a lot of) pops= 3 blue center corners popped off. 2 blue center edges, 1 green white edge, Its still solved right?

3. Is there no limit now to minimum competitors required for a competition?(earlier it was 12 AFAIK, not sure)

1. Who knows...apparently the regs aren't renumbered when they are deleted, even though I think they should be (I know I would be willing to go through and renumber them)

2. No. The centers are acceptable, since it's the same colour, but the edge is not, since it has 2 positions.

3. It's recommended minimum of 12 in the guidelines, which it has been at for a few years now
 
2. No. The centers are acceptable, since it's the same colour, but the edge is not, since it has 2 positions.
Well, An edge on 5x5(at least shengshou) can go inside in only 1 way(if we dont talk about the big middle edge than never pops)
3. It's recommended minimum of 12 in the guidelines, which it has been at for a few years now
Yes, this is what made me ask http://www.worldcubeassociation.org/results/c.php?allResults=All+Results&competitionId=BogorOpen2013

The Regulations are not renumbered because many individual regulations reference other regulations elsewhere. Also, it makes posts from different time periods easier to reference - if you're looking at an announcement from 2009, you shouldn't have to dig up a copy of the 2009 Regulations.

Feel free to correct me if I am wrong but I do believe that if any organisation changes their regulations significantly, then they do actually dig up regulations from previous dates to sort out retroactive issues. Would it really be that hard to store former versions of the regulations on the WCA site with their dates of activity? I mean, they would probably hardly be used but just in case of retroactive potential problems they would still be there.

That's what I was thinking. It's just one more click to get a former version.
Again, in terms of references to other regs, I'm more than willing to go through them all
 
Why do we have D1c? "During the solve, the competitor must use only his feet to touch the puzzle. Penalty: disqualification of the attempt (DNF)."
I think it is absorbed by D1b: "During the attempt, the competitor must only use his feet and the surface. Penalty: disqualification of the attempt (DNF)."
Attempt = solving + inspection. If a competitor can use only feet during the attempt, why do we specify he can touch a puzzle with his feet during solving?
 
WCA Regulations 2013

I want to point you all to this thread here about slice moves.

http://www.twistypuzzles.com/forum/...d&sid=e85500c2e31eaac241f11732ef07340f#unread

The poster, Konrad, asks some interesting questions alright.

Inner slice moves (f,b,r,l,u,d; M, S, E) are no longer defined in the Regulations 2013, but we have still "Multiple Outer Slice Moves"?

Weird indeed!

How should we write slice moves using WCA notation?


Does anyone know?

So the new 6x6x6/7x7x7 notation will include things like "3Rw"?

That's disgusting.

It's true. Here are images of 6x6 and 7x7 scrambles I generated using TNoodle, the official WCA scrambler. I do like the prefix notation without the "w" for 6x6 and 7x7 better.

Edit: I think they eliminated slice moves (M, S, and E) so that all moves in an FMC solution would count as 1 move.
