 Posted: Sun Sep 02, 2007 2:20 am    Post subject: 3 On VI: The first roll has 18 on two adjacent sides and 10 on two opposite sides. The second has 7 / 11; the third has 6 / 16. That gives three different sums for the opposite sides, so all faces are represented. In the third roll, to get 6 from the two adjacent sides involves one from the pair summing to 10 and one from the pair summing to 11: 18 / 10 :: 5/_5 | 4/6 | 3/7 | 2/8 | 1/9 _7 / 11 :: 1/10 | 2/9 | 3/8 | 4/7 | 5/6 _6 / 16 :: The first and third cases are right out as they have a duplicated number. Next, to make 7 for the second roll could use either the first number from the first pair of opposite sides or the second: 18 / 10 :: 4/_6 | 4/_6 | 2/_8 | 1/_9 _7 / 11 :: 2/_9 | 2/_9 | 4/_7 | 5/_6 _6 / 16 :: 3/13 | 1/15 | 5/11 | 6/10 Only in the fourth case is it possible to form 18 from two numbers: 2 and 8 opposite, 4 and 7 opposite, 5 and 11 opposite.

 Posted: Sun Sep 02, 2007 9:03 pm    Post subject: 11 Interesting thing about the dice problem. I showed it to a workmate who has mildly autistic tendencies (I don't know for certain if he is autistic, but he does have a kinda "rain man" vibe about him). Anyway, he solved it in his head in about 5 minutes. Unfortunately, his solution was rather different from the one I submitted Weird how people's minds work, isn't it?

I think close might not be the correct word here

There is more to the numbers that you can backtrack on now. but they actually served more than one purpose for me I can comment on after someone solves that part.

 Posted: Wed Sep 05, 2007 3:48 pm    Post subject: 16 Nauplius, the one pupose was confirming the anagram order, but the other purpose was more of a distraction on where to start. The puzzle was solvable without them...and in my opinion, it would've even been much easier. Part of the difficulty was giving too much information so the starting point (focusing on the common trait of the words) was less obvious.

 Quote: For 'D & A' - The first step is figuring out what D & A stand for.

I think everybody will have realised that already. Any chance of a meatier hint?

 Posted: Sun Sep 09, 2007 1:33 am    Post subject: 24 Bigger hint for D & A D & A do, as ralphmerridew noted, stand for Down and Across. This puzzle has nothing to do with crosswords or anything like that, rather each item in the series should be interpreted as an instruction. Furthermore, do not forget that this is a sequence puzzle, and the best sequence puzzles are those which find new and original ways of representing sequences which are very, very simple. This was, incidentally, my favourite puzzle of the entire competition.

 Posted: Sun Sep 09, 2007 7:51 am    Post subject: 25 I think DnA is where: Ds count the downstrokes and As count the across strokes of a digital number display, like a calculator or clock. The series given is 1 (2 downstrokes) through 10 (6 downstrokes, 2 from digit 1 and 4 from digit 0, etc) and the required answer should be 11 through 14 as per: 4D 4D3A 4D3A 5D1A

 Posted: Tue Sep 11, 2007 5:27 pm    Post subject: 28 I'd say your track looks pretty good Nauplius The one you left out can be said to be ambigious since two good answers can fit...although if you google both possibilities one result is twice the other, but it's irrelevant since it doesn't affect the puzzle's outcome.

 Posted: Fri Sep 14, 2007 1:05 pm    Post subject: 29 I'm lovin' this - kicking myself at those I'd missed - Bizarrely I *did* figure out what D&A stood for, but made no more sense of it. oh well... As for birds - good puzzle, but for one thing - too American! Well, that's not strictly true - it can be American if we know it is so... "clause = Grandfather" - huh? must be an American thing? I could say the same for "undercover = Brother" and "fortunate = Son" too... BTW, Sugar = Daddy, right?, or maybe it's 'baby' in the US?_________________http://www.ukpuzzles.org/

 Posted: Fri Sep 14, 2007 3:35 pm    Post subject: 31 "Grandfather clause" refers to a clause sometimes added to changes in regulations that allows existing objects that otherwise conflict with the new regulations. (For example, laws related to emission standards may except classic cars.) The term comes from a law that a person must pass a literacy test to vote, unless he, his father, or grandfather was eligible to vote before a certain date.
