Really enjoyed the extra bit at the end this year! Looking forward to 2017's calendar.

@Lyra: I'll email you if you are one of the winners to get the rest of your address!
Matthew
                 Reply
I acccidently sent the form without all of my address :/ It's just the street, can I send the postcode and that it is in Germany "somewhere else"?
Lyra
                 Reply
@Lyra: Yes, I'm happy to send the prizes internationally. Glad you enjoyed the puzzles. Merry Christmas!
Matthew
                 Reply
Will you be able to send to outside of the UK? Was really awesome! Definitely joining again next year. Merry Christmas!

Hi Matthew, thx for the wonderful riddles. I still get a 4-digit answer for Dec 3rd, can you help me out? Thanks so much!

@Wait: The 25th door only contains the entry from for the murder mystery. You now have all 24 clues. Good luck!
Matthew
                 Reply
Is there going to be a clue behind door 25? Or do we have 24 clues in total?
Wait
                 Reply
@Applause: Glad you enjoyed it. Yes - I am planning to do another next year
Matthew
                 Reply
This calendar was spectacular, especially the murder mystery. I'm already looking forward to next year's (also, could you please confirm that there will be another next year?)! Thank you so much for all of the work that must have gone into this. It was extremely fun.

@Panda : You need to wait to solve today's puzzle until you have 1-24 solved. (I saved this question for late in the calendar so you for have to wait too long.)
Matthew
                 Reply
I'm not sure I understand today's (Dec 21) question. If we were to calculate the mean of all answers that are multiples of 3, does that mean (i) effectively we can only solve today's question on Dec 24 or (ii) we only need to consider the answers from Dec 1 - Dec 21?
Or am I misinterpreting the question completely?
Panda
                 Reply
These puzzles are getting mega meta!
Another Matthew
                 Reply
@Lyra: The first row (1) is row 1, making (1 1) row 2, (1 2 1) row 3, etc
Matthew
                 Reply
For row 8 in Pascals triangle: is the very first (one 1) row 1 or row 0?
Lyra
                 Reply
@Another Matthew: Correct, you're looking for the sum of the two numbers on the centre spread pages (one on each page).
Matthew
                 Reply
Since some people use Kindles, it seems natural that a page is just one side.
Another Matthew
                 Reply
How is the relationship between page and page number defined in the book for #15? Is it defined by the page numbers of the book (i.e. the page numbered 1 is page 1, the page numbered 2 is page 2, and so on), is it defined by the front and back of a piece of paper (e.g. page 1 contains page number 1 on the front and page number 2 on the back), or is it defined by folding all of the pages horizontally and nesting them inside of each other (e.g. page 1 contains the first two and final two page numbers)?

@Steve paget: Link styling was strange. They're now underlined to make it easier.
Matthew
                 Reply
Ah, ignore me. I didn't see that it was a link!
Steve paget
                 Reply
I don't know what the AVE Game engine is (Day 11)! Do I have to download something?
Steve Paget

@Mike: I've added a clarification to puzzle 5. Glad you're enjoying the puzzles!
Matthew
                 Reply
I think problem 5 needs clarification. By numbers, you mean positive integers? Does the sum just consisting of the number 35 count? Are these ordered or unordered sums?

Thank you for all your hard work on this, it's a lot of fun.
Mike

@k: Don't assume anything! All should become clear at the end...
Matthew
                 Reply
Can we assume that all meta clues (like 8 and 12) are true?
k
                 Reply
@Matthew: It was definitely a surprise; well played :)
Wait
                 Reply
@Wait: Nope, I thought it would be a nice surprise to be told this after 8 days!
Matthew
                 Reply
Wait, we aren't guaranteed that the clues are correct?

@Rob Rowlands: Thanks for passing it on. I've corrected the post to say end of 2016 (!).
Matthew
                 Reply
Hello Matthew, your advent calendar idea seems wonderful. I've retired from teaching but still attend meetings of the Camborne (Cornwall) branch of ATM. We have our Christmas meeting on Saturday so I will pass this on.
You might have already had it pointed out that the closing date for entries is the beginning of 2016, but if we can't work out what's happened there then I don't suppose we have much chance with the competition. Happy Christmas, from Rob Rowlands
