@A: Aha, I should have thought of this! Puzzles completed :-)(anonymous)
×1 @Dean: you can also go through each answer one at a time and change a digit; if the number of wrong answers goes up then your answer for that question was correct×1 ×1

×1 ×1 @Dean: Yes, I'm planning to change how that bit works. Check back tomorrow or the next day for a more fun finish! ×1
Matthew
×1 A bit harsh that we can’t tell exactly which answers are wrong! I won’t have time to revisit every puzzle - and its kind of less fun redoing something that is already correct... :-(
Dean
Nice puzzle set as always. For those of you using the "plain/printable format", it does drop 1 key piece of info on clue 12 that can lead to an unclear clue: the digits are already in the right order. If you allow for rearrangements, there's 2 possible strings that satisfy all the clues I think.

I couldn't get 19, so I brute forced Santa's location using what I already knew and then used that to brute force 19. Ha! (it turns out I was off on 19 by 34 - I still don't know where I went wrong)
This year's calendar was great. Thanks :)×1 ×1

×1 ×1 No good idea for the 21st, so I brute forced it, and chances are a messed it up are high!

Loved the puzzle today. Can't tell if I made it more complicated than it needed to be, but either way it was fun!×1

×1 There seems to be an issue with the text formatting of 18, if you click hide this puzzle and re-open 18 the text loses it formatting and becomes:
The expansion of \((x+y+z)^3\) is
$$x^3 + y^3 + z^3 + 3x^2y + 3x^2z + 3xy^2 + 3y^2z + 3xz^2 + 3yz^2 + 6xyz.$$
Until you refresh the page

there's a typo in the puzzle for the 18th: you wrote y^2 and z^2 terms instead of ^3
(also I agree that the puzzle for 16th was a banger)×1

×1 Nice one today (16 December) :)
Did he?... did he really?... starts to look like it... yes he did! :D×3 ×6 ×3 ×1 ×2

×3 ×6 ×3 ×1 ×2 @Moss: You were correct: as you were writing this, I was correcting the puzzle. It should now be correct ×1

×1 Hi Matthew
If I'm wrong, don't bother to answer, but I suspect there might be an error in the wording of Number 11.
I don't think it's possible to solve it right now.
Cheers
