Just one question.

8. Dioxides
Can the molecules lie diagonally or are all connections orthogonally?

All moleculues/dioxides puzzles i have seen had orthogonally connected atoms.I assume the same here.

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 ?

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.

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.

The molecules can not be connected diagonally, they have to be joined orthogonally (as in the example).

Well it depends on availability of the types. 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.

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.

Hi. We looked into your solution. 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.

hi..i have understood the question incorrectly.i misinterpreted 'all given diamonds should be used' as something else....like i thought that each of the diamonds have to be present in atleast one card and the position of the diamonds should match that in the card..took me some time to realise this after i went through your reply.......now got it.!thnks a ton for going through it and explaining me my mistake

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?
