Sorry but no. We have our schedules decided in advance too, even though we release things just a week before. There's other contests to consider too. Also, this test is just 60 minutes, and we have had even tests of 120 minutes or more on the same weekend as other competitions. With the puzzle calendar as it is, its inevitable to have many overlaps. We try our best to avoid overlapping with National Championships and major offline events, but unfortunately sometimes that can happen too.
And Rajesh, the test is from Friday to Monday, and Brain Games is only during the weekend, and not a full day event. Plus I think its lovely to have a nice test to direct that audience to on Sunday  |

Agree with you Prasanna. We can make audience at aware of LMI and direct them to this test.: )
Looking forward to this test.

Check the Instruction booklet. There's a reasoning there. Screen Tests are designed to test visual skills. We've made an effort to make the difficulty easier this year, but I think its important to keep this a visual skill based test. |

It basically means that, for the rule that says "if X is there, then Y should happen", you should also take into consideration "if X is not there, Y shouldn't happen". Take XV for example, if there is an X between 2 cells, then the sum of those cells must be 10. Because converse rule applies, if there isn't an X between 2 cells then the sum cannot be 10. |

Country : Japan | A question about scoring:
- Each sudoku is worth points varying from 25 to 200.
- The exact point will be computed after the test is completed as “average of 30 best times (in seconds) for that sudoku”, subject to the minimum and maximum values.
I’d like to know how the exact point will be adjusted from 25 to 200 if an average time is less than 25 seconds or over 200 seconds. |

Hey Yuhei,
25 and 200 are the minimum and maximum values. i.e. no Sudoku will be less than 25 or more than 200 points. |

Yup thats what it means. But note the converse rule too. More than just solution, there's a way to look at an entire solve by going to the Sudokucup Guest League page and seeing others solve my Repeated Neighbours on 24th July  |

Country : India | Regarding JOCs -
We have spotted that there are 2 possible digits for some of these. Answers will be (and have been) accepted if they have a valid reasoning behind them that myself and the testing has missed. So if you get a JOC marked wrong but used a logical solving path, please let us know.
This post will remain restricted so only those who finish the test can read this and make the claim, if necessary. Sincere apologies for the double solution. Probably a good idea not to hold variant JOCs in the future. |

Country : Germany | uvo posted @ 2013-11-15 4:23 PM I'm quite sure both my solutions for B2 (JOC Repeated Neighbours) and E5 (JOC Killer) are correct.
B2: Possible places for digits 3 are R1C4/6, R2C1/3, R6C1/3, R5C4/6. R6C1 implies R2C3, R1C6 and R5C4; R6C3 implies R5C4, R1C6 and R2C1. Not sure what the intended solution is, but both R1C6=3 and R5C4=3 should work.
E5: R1C3=6 would imply R6C4=6, which is impossible due to the 13 cage; therefore R1C4=6. |

I found some of the A puzzles hard, but some of the E puzzles easy (particularly Search 6 and Arrow ) -- I'd run out of time by then though! I'm not clear what determined which section puzzles went into. Time limit per puzzle was great; overall time limit seemed a bit tight given that there's bonus scoring for quick people anyway. |

Country : France | I think that my answers for B2 and E5 are good :
B2 : in row 5, 3 is not in columns 1 and 3 because R5C2 is not shaded and 3 is not in column 6 because R5C4 is shaded. so 3 is in R5C4.
E5 : in row 1, 6 is not in columns 1,2,5,6 because of sums 7 and 8. If 6 is in column 3 so R6C4=4 and sum 13 is impossible. So R1C4 = 6. |

Anyway, yeah, some of the JOCs seem to have multiple solutions; I suppose I won't comment about that, as they are already answered. Next time, try making a solver or something that iterates over all possible grids to check validity :P
I'll comment on E4 instead, where the rules in the applet is not complete (no "converse rule applies", no "only three cells in the same region are counted").
Gah, missed E8 by 13 seconds. I should have skipped some of the puzzles earlier. Wonderful puzzles as always :) even though I'm stuck in some of them for the entire five minutes. :P |

Country : France | auroux posted @ 2013-11-15 10:27 PM I got really annoyed when I spent a lot of time on the first two JOCs and missed the first one because I couldn't figure out what "JOC" stood for (I really wasn't expecting such a puzzle type), and the rule written in the margin did not mention "just one cell" either. I know it's my fault for not bothering to read the booklet, assuming the types would be easy and classical as in the previous screen test -- but come on, would it have been too much to write "Just One Cell" instead of "JOC" in the problem name or to put it somewhere in the instructions??? (After getting the second one wrong, at least I read carefully the message before submitting and noticed it said "one cell" instead of "all cells" as I had thought, and so I could go back to solving it.
Otherwise, this would have been a good test, but I was so upset after hitting those first two JOCs that I really couldn't focus on the rest the way I would have wanted. At some point I was so out of it that I started hitting "show" to reveal the puzzles without even bothering to read the rules and lost more time because of having to understand what the puzzles were AFTER they were displayed... :(
Oh well, really largely my fault for not reading the booklet, in spite of the above complaint.

Yes, of course, I agree.
The good news for the organizers is that it'll not be too hard to cancel these puzzles as we know exactly how much time each player spent. The only problem is the 60 minutes time limit. |

I'll comment on E4 instead, where the rules in the applet is not complete (no "converse rule applies", no "only three cells in the same region are counted").
This was mainly because of the rules being too long. The rules have now been shortened to be accommodated on the applet. Thanks for the notification. |

Heh, I think that may have bitten me. When I was solving E4, I don't think the "No arrow means no sequence" part had been added. I looked over my solution, glanced at the rules summary, saw no contradiction, and submitted and moved on. Not sure I would have had time to find the correct solution even if I had the right rules, but oh well. Much happier with my performance regardless of the issues. I still wasn't going to finish, but it was great to get so much closer. Thanks for the cool puzzles! |

I'm curious whether people actually continue solving after the time is up or not. If they do, you can try removing the seconds spent in B2 and E5 and count the unofficial time for the length of time spent on B2 and E5? (For example, in my case, I spent 300 seconds in B2 and like 50 seconds in E5, so I gain an extension of 350 seconds, counting the first 350 unofficial seconds as official. )
(Ok this suggestion is a bit biased since with an additional of 300 seconds or so I would have finished the test. :P ) Edited by chaotic_iak 2013-11-16 9:23 AM

This would be ideal if everyone continued solving after time. But thats not the case, so its unfair to those who stopped. |

Country : Indonesia | I can't see a good way out then. My opinion would be to drop B2 and E5, then let the total score be multiplied by 3600 / (seconds spent in all other puzzles)...basically the same thing as you suggested. I feel something is unfair about this, but I cannot really point it out...yeah it's weird. xP |

About the evil JOCs, firstly, I'm really sorry We're looking at a way to fix the problem. We're thinking of going with canceling B2 and E5, and awarding [points scored over remainder / seconds spent over remainder * seconds spent on B2,E5]. We would like to know general thoughts on whether this is fair.
If two players solved correctly the 28 remainder sudokus in the same time, and one spent much time on B2 and E5 as the other, would they get finally the same number of points ? |

Yes. I think in the event of the puzzles being canceled, that is fair. |

The test was fun, but kind of stressful. Good practice. |

I'm curious whether people actually continue solving after the time is up or not. If they do, you can try removing the seconds spent in B2 and E5 and count the unofficial time for the length of time spent on B2 and E5? (For example, in my case, I spent 300 seconds in B2 and like 50 seconds in E5, so I gain an extension of 350 seconds, counting the first 350 unofficial seconds as official.)
(Ok this suggestion is a bit biased since with an additional of 300 seconds or so I would have finished the test. :P )
This would be ideal if everyone continued solving after time. But thats not the case, so its unfair to those who stopped.
I thought about what could the best decision to have a fairer ranking, given the 2 wrong puzzles. It's a bit complicated and I don't know if it's technically doable, but that's what I thought:
-cancel B2 and E5 and remove the times of both puzzles for every player.
-calculate a new time limit as 3600- (maximum time spent by a player on puzzles B2+E5 )
-For players who didn't finish the 28 puzzles in the new time limit, you've to estimate points for the last puzzle (the puzzle player was solving when the new limit was reached ). For example, you can take a percentage of points proportional to points gained and solving time of the player in the old ranking (if a player solved his last puzzle in 200 seconds and the new time limit was reached after 100 seconds, assign 50% of the points the player gained ).
In my opinion, it's the best way to do as if both puzzles never existed.

I'm sorry Denis, and others, for the problems. We will indeed work to make sure these don't happen in future Screen Tests. The problem here was the rules were so long they slipped out of the interface even though we entered them right. I confess I hadn't considered that possibility, and definitely will in future. About this time I agree that Rossini would've been a big problem for folks who hadn't seen/remembered the rules on the guide and relied on the interface. This seems a harder issue to fix than the 2 JOCs which can be dropped as suggested previously. |

First of all, I really enjoyed the set, so thanks for putting the puzzles out there!
I don't necessarily care about my ranking, but wanted to throw out there that, because I didn't think I was getting to the end, I did get bitten by the lack of converse (aka I was low on time, took a guess, and my solution was correct without the converse ). I don't think there is a way to really fix that one (aside from either the JOC solution of throwing it out, but now we're possibly talking about taking 1/4 of the time spent on the test out, or alternatively grading that problem correct if they hit a correct solution without the converse rule ). I do have the feeling that I would've come close to finishing Arrow had all of the rules appeared on the screen, but I don't know if I would've actually done it, so I'm certainly not going to push for any "advantage" from that puzzle. |

A nice test with nice puzzles. However, given that on the last sudoku screen test I ran out of time, this year I skipped a couple of puzzles more quickly. Obviously, I then found I had several minutes wasted at the end. Clearly this is my fault, and there was a note somewhere that these puzzles were generally easier than last years, but I didn't realise just how much easier they would be. 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? Anyway, thanks for the test; I really enjoy screentests, and look forward to the next puzzle one. It's also nice to only have to set aside an hour or so, rather than two or more! |

Country : India | Few notes :
Firstly, we're making some changes to the score page now (computing bonus, canceling B2/E5 using my previous suggestion, and computing the changes ). So if the score page does weird things for a while today, please bear with us
Secondly, we're not considering E4 errors for the bonus, and the bonus will be computed for the rest as announced. Something that isn't announced is, even players who have just one Sudoku wrong are eligible for bonus. So its either players who have just one grid wrong, or players who have 10 cells wrong across multiple grids.

Overall it's a fairly nice test, I enjoyed it. It's a bit unfortunate that there was no JOC example in the test case. For submitting, after ten puzzles without popup I was pretty sure I had done something very very bad when there was a popup after the eleventh puzzle. I was confused and read the popup twice very carefully, just to more than double my solving time. 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? |

Even though the B2: Repeated Neighbours has issues, I wanted to share what I did.
'3' cannot occur in R5C1, R5C2, R5C3, R6C2 due to the puzzle rules. If '3' is in R6C3, it also has to be in R5C4 but since it is a 'Just One Cell' sudoku (so, non-unique), I submitted R6C1 as '3'.
Pretty cheeky huh? Did anyone else get this weird funda? ;-)
Also, an interesting thought about using 'uniqueness' in Just One Cell, it sounds funny though.

"...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 ).

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. |

(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.

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...

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. |

Is there a way to make the scoring more transparent? I have no idea why the ranking is the way it is, for example places 19 and 20 look especially strange.
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. |

Country : India | Bit late to posting a summary because of traveling and then falling ill. Anyway, just a few quick notes.
Firstly, congratulations to jaku111 (2982.4 points ), TiiT (2882.6 points ) and deu (2865.1 points ), the podium finishers.
This screen test definitely had some things that were bad, pretty obviously my own doing. But the biggest positive I'll take from it is that the general format/timing/etc. seems to have been a success. I wanted many solvers to be able to attempt most of the grids, and this is what happened.
Also, about Just One Cell idea, I think its probably fine to do but it takes more checking, and probably not using variants with too many constraints.
The interface is superb as always, but as usual had some feedback directed towards it. Firstly, the color button implementation, I think, was fine. It'll stay. I'm still not sure about undo button being limited to 2/3 clicks. One change we must work to implement, especially with this easier format, is to enable a solver to visit back to a grid if the solver goes through all 30 grids with time remaining.
Thank you all for participating, and also for the feedback |
