Country : Germany | Does the 15 second waiting time before each puzzle (which you can skip according to the booklet) count for the total time? |

Country : Indonesia | For B2, does it mean that at least two of the squares adjacent to a shaded square contain the same number? It's not quite clear from the description; can anyone post a fully solved Repeated Neighbors Sudoku puzzle (obviously not the one in the IB)? |

It does not count in your total time. |

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  |

Ok, Thanks! |

I know this is a lot to ask, but is it possible to make the applet less sluggish in the future? Moving and typing feels very slow compared to Nikoli. Also, can you implement backspace as delete as well? Thanks for bringing it up. For future contests, we will have a close look at the user-interaction part to see what can be improved. I hope it is equally bad (or good ) for everyone. |

It has been mentioned in the Screen Test Guide. I'm sincerely sorry about your experience, but it was definitely informed.

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. |

Oh, you're absolutely right, just I missed some sentences, my apologize.
I was wondering what the word JOC is during the test... shameful (ToT ) |

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. |

Country : Indonesia | @Gotroch: How can you distinguish 5 and 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 |
