Thank you, I was worried. Thanks also for the puzzles, makes a change from my usual sudokus. I especially liked 3, 9, 11, 16, 21 and 23.

Do we get a confirmation email after submission of the entry form? I never received one, so I'm not sure if I am entered.

Thanks for the nice puzzles!

@Seth: If you find them on the map then that's all you need to do. (And if you didn't find them yet then the entry form won't appear so you definably did everything you need to do.)

In the form today, there was nowhere to input the three locations -- just my name/email/etc. I found all three, though, and the page says so. Do you have it set up so the form only appears for those who found all three? Or is there something else I need to do?

@Emily:
Saw your earlier comment, nevermind!

If one of the inhabitants lies about a clue, does that mean they will lie about all of their clues?

@Matthew: There was a mistake: I'd written the rows in the wrong order. I've now corrected it.

For Day 23, I assume the 3-digit numbers are read top to bottom and left to right?

So the bottom right corner must be odd (the ones digit of an odd number) and it must be even (the ones digit of a multiple of 4)? Isn't that a contradiction if I'm understanding the problem correctly?

@Reza: Yes, that information will appear below the Advent calendar on Christmas Eve.
Matthew

Is it possible to send answers for checking on the website like last year, to find out how many are correct?
Reza

Too bad there's not a prize for finding everyone early...

This search space is so large, it's way harder than trying to find Wally like in the children's books. Best to read everything carefully looking for any clues, and then solve all the puzzles and logic before searching randomly!
Did you know Wally is called Waldo in the US, Walter in Germany, and Charlie in France?

@(anonymous): Yes. Every islander will either always tell the truth or always lie.
Matthew

@Matthew: If an inhabitant is a liar, do they always lie?
(anonymous)
                 Reply
@Jonathan: Yes, they could all be lying. But one might contradict another at some point to make this impossible...
Matthew
                 Reply
Is it correct that the rules allow for all four inhabitants to be lying about everything?
Jonathan
                 Reply
No, this means the islander comes from Rum, this island that I am denoting by red... This will hopefully become less confusing once the blue and orange islanders have spoken.
Matthew
                 Reply
Does a red box mean my answer is wrong? Is it one of the islanders trying to mislead me?
