Lots of fun! Some of them were pretty darn hard, but most of them were perfect for the quick online solve. It was definitely in reach even for someone like me to finish within the time limit. A few of them were a lot harder to do without a pencil! A good memory exercise for me to see how much of that I could keep in my head. The colors interface would have been nice for bifurcating at times if I could have figured out how to make it work for me instead of changing the color of everything when I clicked on a color. |

So I worried that somehow the interface thought that I had submitted a puzzle with a non-1 number of filled-in cells. It would be nice to be warned about the warning. |

(Semax's point too ) I agree, we should've said that this will happen. That'll be noted for next time (if at all we do variant JOCs again, that requires a think through in itself ), and having a JOC in the example series on interface is also a good idea.

In the solving interface, it would have to better if we could have been given different colors for backtracking the puzzles. |

Hey my friend-despite-the-fact-you took-part-in-WPC, Interesting reasoning, although it is wrong. 
Yes, I am also an 'exception' B- ) B- )
"...If '3' is in R6C3, it also has to be in R5C4..." you can conclude that 3 in R6C3 is not the answer of the JOC sudoku, but you can't conclude that 3 cannot be placed in R6C3 (it can be one of the multiple solution).
I was in such a hurry about submitting my solution after having found the 3 in R5C4 that I didn't thought that it could not be possible, as it has to be in R6C3 as well (what I've seen however).
Fred
I know, I feel so stupid. I had a hearty laugh after I realized what I did. |

Country : United Kingdom | detuned posted @ 2013-11-18 5:59 PM I'd also like to know what is "incorrect" with my E5 - JOC5 - Killer solution.
I entered R1C4 as a 6. The reasoning goes like this: 13 in the bottom right is either 256 or 346 - either way we certainly can't have R6C4 as 6. By the law of leftovers this means R1C3 cannot be a 6. The 6 in R1 must therefore go in C4 because it can't be part of a 7 or 8 cage...
edit: n/m I see e5 seems to be missing on the results page, i assume it's a bad puzzle...

I agree, felt a lot faster on the harder puzzles once I started trying out things. Maybe one or two levels of undo to deal with actual typos? |

We actually discussed a lot about this, and it is the reason why we ensured that if you change color, it'll change throughout, meaning color changes are only for player preference rather than guesswork. With undo, we're not sure what is a great way of doing things. My point is someone solving could honestly make a mistake and it'd help to undo to retrace. So the only use isn't guesswork, and I'm always in favor of keeping things that help normal solving even if they could be used towards shortcuts, so we decided to keep it. Maybe restricting to one or two levels is a good idea, but I personally am still non-committal to the same. Would love to hear more views on it.
I'll read back now to other points and queries. I only addressed the more pressing ones while I was away conducting a puzzle event here simultaneously over the weekend. |

As mentioned in my post above, we deliberately decided to keep it this way, and keep the undo button as the sole method of backtracking. |

And another little thing that I don't understand: Why is there an automatic submission after 5 minutes? There are so many situations where this is bad. Can you tell me one situation where this is good?
It is probably the same reason why normal tests have a time limit instead of just saying, solve and submit whenever you like. Here the expected difficulty per grid is really low compared to normal tests, so a per grid time limit adds to the competitive aspect of things. In other words, I'd just say its easier and so we can experiment with a different quick-fire setting for it so we do. It is the general idea of a screen test (the same was used in WPC 2011 too ) that we've tried to extend to Sudoku. The bigger challenge is in ensuring that at least most of these are easy enough for everyone to submit some in spite of time limits. Looking at the general feedback I feel at least that has been achieved this time. |

Given that a lot of people won't expect to complete every puzzle, 'tactics' and puzzle choice becomes very important (given that the strategy 'never skip' clearly cannot be optimal, except for the best), so I wonder if it would be better to have a more accurate gauge of the level of difficulty of the puzzles, if possible?
We were actually worried about this. Ideally the solution is to have a system where a solver can get back to skipped puzzles only IF all of the order is finished before time. Unfortunately we did not have the time this time to get that system in place, so made do with the note in the instructions. A more accurate gauge of difficulty is interesting though, just in case the system itself proves difficult to implement. Is there any suggestion on how this can be done? It'd probably become too formulaic if we say that a player with X ratings is expected to be on the border of finishing, but I see that as the most realistic way of providing an idea about difficulty. |

A few things -
B2+E5 have been canceled and points have been added considering the amount of time wasted on those two puzzles. Timothy wasted more time on them.
E4 is not considered for bonus criteria, because some had a bad experience on it with rules being misplaced. JOCs are considered separately and only their own points are removed. So, Timothy has only 6 cells wrong across the other grids (E2 and E6 ) and is eligible for the bonus.
We'll add a few notes explaining the scoring add-ons on the test page soon. As of now this is the gist. There is the drop down list with the choice of Points instead of Seconds where you can check about the points being given for each grid. |
