Posts: 172 Country : ITALY | forcolin posted @ 2012-08-30 1:50 PM I remember from the old time that Osmium is one of the few elements having a possible oxydation state +8 therefore forming the tetraoxyde OsO4. So my first impression was that the puzzle is wrong. But I have consulted the literature and found that the dioxide is also possible at a lower oxydation state, so the puzzle is chemically correct. I have a question about Dikuro. The instructions say that "no digits can repeat in a sum". but in the example posted by Serkan there are some blank boxes in which no sum is indicated. Can digits repeat in a row or in a column if no digit is show at the beginning ? |

Country : India | Administrator posted @ 2012-08-30 2:06 PM forcolin - 2012-08-30 1:50 PM The format is slightly changed, and the blank boxes with no sum are replaced by "?" (also seen in the example booklet). Digits will not repeat if there is a "?" instead of a sum. I have a question about Dikuro. The instructions say that "no digits can repeat in a sum". but in the example posted by Serkan there are some blank boxes in which no sum is indicated. Can digits repeat in a row or in a column if no digit is show at the beginning ? EDIT : Further clarification on Dikuro : Even at the top of the column (or left of the row) where there is no "?" or no digit (also seen in practice pdf), digits can not repeat. Also, It will be obvious from the contest puzzle that "?" can represent 1 digit or 2 digits. |

If they are already available, whoever is aware of it will surely link to them (like Bram did to Naoki Inaba's site in the last puzzle test). Also in the last puzzle test I made a practice puzzle or two, and so did some other authors like Gorogoro (owner of Puzzle Graffiti blog). But its not always possible, since its pretty time consuming to figure out an unfamiliar puzzle type enough to create something of it. |

Posts: 1803 Country : India | prasanna16391 posted @ 2012-09-01 11:54 AM I think this is my worst performance of the year. At least for 7 puzzles I reached contradictions, and then solved them after time and realized how stupid my errors were. I liked the Yajilin a lot, but not competitively, because you never know when you miss one black cell somewhere or other, and you always have that feeling some clue might not be satisfied with the added diagonal constraint to look at. Dikuro, Digits Rotation, Disposition were among my favorites too. Thanks for the test Riad. |

See the intersection of 8 card and 5 card according to your labeling and make note of all diamonds used. There are 2 diamonds in there that are not used by either 8 or 5. Thats one mistake. I guess there are others. Remember all diamonds must be used by at least one card. |

Posts: 187 Country : New Zealand | kiwijam posted @ 2012-09-02 5:12 PM I made so many errors, I can hardly read some of my answers! Silly brain. Very 'dense' puzzle types, these will be great to do over a longer time period. Thanks Riad, I hope you will continue to make the week-long tests that you are famous for too. I really look forward to those. Maybe LMI could host one? |

Posts: 148 Country : France | Ours brun posted @ 2012-09-02 8:41 PM Poor playing means poor score... Not that I did that many mistakes, but on about every puzzle I had the feeling of being twice too slow. I needed as much time on the Dikuro as on the Diayajilin despite the fact that I had to correct a mistake on this last one. I stared at a half-filled Diversion for nearly 10' without doing or even trying anything, and finally solved it in less than a minute... just after the end of the test. And why exactly didn't I try the Diversion without borders although I felt confident on this type ? Anyway, my feeling about the test is that there were some very nice puzzles (amongst the ones I solved, Diayajilin and Dikuro in particular were great), but that several types are amongst the ones I prefer to see on a "one week test" rather than on a timed event (notably Diamonds, Digits rotation or Divergence). On the other hand, given the coming of WPC, it could prove useful to try ourselves at some unusual types of puzzles under the threat of the timer... Thanks for the test Riad. |

Posts: 315 Country : The Netherlands | Para posted @ 2012-09-03 3:18 AM I really suffered through this set breaking basically every puzzle. But solving them now afterwards they were all really nice. The ones I didn't solve in competition are actually the once I thought were the nicest. Edited by Para 2012-09-03 3:20 AM |
