CORDIAL MINUET ENSEMBLE

Wouldn't be hard since the creator can choose the 12 letters.  "Cordial Minuet", for example, uses exactly 12 distinct letters.  That could easily make some other phrase (that could then be entered in the password boxes) if the letters were substituted for other letters.  And we have found symbols that match pretty closely -- the D and the I.  But yes, the theory would have a lot more credence if there was more than just one matching pair.

Though I just realized, upon closer inspection, that the I symbol doesn't close completely -- I didn't realize that until just now.

P.S. I never actually said I believed my theory was right   Just something that popped in my mind a while back.

To expound on my reasoning above, there are 5 possible ways to order the amulets:

1) The order they were given out
2) The order of their zodiac sign
3) The order given by their filenames (they all started with numbers)
4) The order of number of notches
5) The order of the letters on the back

2) and 3) give the same ordering (and would suggest the 13-notch amulet is the "11th" amulet, with no indication that there's a 13th amulet).  5) is likely the same as 2) and 3), given what has been said and shown in this thread, though obviously we can't be certain until we see all the backs.  1) is probably irrelevant in my mind, but it's possible it has some meaning.  4) is the only ordering that suggests the 13-notched one is in 13th place (and that we're missing the amulet that would fall in the 11th spot).

Not saying the number of notches is meaningless, but I'm not convinced that that's enough evidence to indicate there's a mysterious 13th amulet floating around.

Yep, which is why I said I'm fairly confident his amulet has V and W on it

That's just referring to the order the amulets were given out, though, right?  i.e. the fact that the "amulet 6" was given out third, etc.  I'm referring to the fact that "amulet 11" has 13 notches.

Edit:  Sorry, reread your post.  Guess we were talking about different things.

I never really considered the order that the amulets were actually handed out.  I just assumed that he wanted the high values ones either on the weekend or at the end of the contest.

D'oh, you're almost certainly right.  I just saw "ram" and immediately associated it with Aries.  But half-goat, half-fish makes more sense for OceanRam.  So yeah, that would put them all in the correct order.  I knew there was some reason I thought they were all in order before today.

But again, that's definitely evidence towards the theory that the day 11 amulet is the 11th amulet, not a 13th one.

I don't think so (assuming you mean the holes).  The dots/holes are present in the original sigil designs.  Other than the big hole at the top of each one.

Not sure what you mean.  There were 12 amulets given out.  Consensus seems to be that only 24 letters will be used.  J was left out, and some letter between T and Z will be left out.  J and Z are the two least used letters in the English alphabet, so there's a good chance Z won't be used at all (could very well be X, instead).

Hmm, I just came up with a somewhat plausible theory (which is a level of plausible above my previous dozens of theories).  I believe that two of the runes we haven't seen may be shaped like the following:

(enjoy my uber Paint skills)
Someone feel free to let me know if you have an amulet that has one of these

Yep, same stamp on mine.

Well, there's the first rune we've gotten that sort of looks like one we've seen before.  The rune for M (the "P"-looking one) sort of (but not exactly) looks like one that shows up on the game board (I'm assuming we don't know what these represent yet -- someone correct me if I'm wrong).  So, running with that idea, if we assume that the column labels represent a 6-letter word, and given the third letter is "M", and given that all 6 letters are different, and tossing out all the letters I've already seen that don't have runes on the board (including J), it cuts down the list to 20 possible words (I think I got them all, but won't guarantee it)

Edit: Also "Humots", which is another demon along the same lines as the 12 amulet demons.  Seems a better choice than any of the above words.

Most of those words are pretty obscure, and none of them really seem to fit the theme, so this is all probably just another dead end.  Though it would be interesting if we do see another rune that seems to match one on the game board.

(Just one of the several winding paths I've been down the last few days)

That's because there aren't really any "solutions".  The code box doesn't check what you type into it at all (except for one single redirection substitution).  You can get to the page after the code box just by appendng the passcode onto the cordialminuet.com/ url, and bypass that code box completely.  All the code box does is make whatever you type into a url.

Edit:  Though now that I check again, that page after the code box isn't a php page like most of the pages on the site, so it's actually not included in the source files, as far as I can tell.  There very well could be a hidden page that you could (though wouldn't have to) access through the code box.

Spent a while today looking for a potential message to decode, but didn't find anything.  What you say about a substitution cipher is true, but it could be something without any grammar (or even actual words).  For example, maybe something that goes in the code boxes at the bottom of the main page.  If you put in the original correct answer, the page says "SOMETHING VALUABLE will appear here SOMEDAY".  Maybe the decoded message will find the "something valuable".  Just spitballing, though.  Unless one of the amulets has something drastically different than what we've been seeing, I don't think we can get anywhere without a message.

Edit:  Only thing I can think at this point is if half of the amulets have the cypher, and the other half have the message, but who knows.

Edit 2:  Just checked -- all the entry box does is concatenate the two strings, and makes a url out of them.
