I'm pretty confident it's been tried more than once (I did, so I can be very confident). But feel free to try again: several cards have been solved by people going over old ground and doing something minutely different.

It sounds like you are keying the deck manually. There's a very handy app here to do it automatically. Saves a lot of pain.

Thanks! That was a much more efficient way for me to disprove everything I had thought of, and a few new theories too.

hi guys.

what if there are two codes being used with the same keystream?
so if we say "if entropy wins outward looks will leave you cold" is the true text and some of the jargon on the page is what its coverted to then we can work out the keystream, then decode the rest.

but what I cant figure out is what bit belongs to what. any ideas?
I have never come across a solitaire cipher btw so please tell me if I'm completely wrong.

I've looked back in the thread a bit, but I haven't seen this idea put forward yet. (Although I'm certainly prepared to receive a trouting if one's warranted.)

Now that we have all the cards available to us, how about trying the order of the playing cards on the prime-numbered cards? In other words, setting the deck in the same order that the cards appear on the prime numbered puzzle cards:

8s, 7c, 7h, 6c, etc... and trying it from there?

I'll have a look at some of the solving webpages and see if this idea holds promise.

Edit: Looks like it doesn't, at first glance (and further searching shows that people have emailed MC about this idea). I must say that I'm not too good with the Solitaire cipher yet, so I might be missing something. However, I also think MC might have been artfully dodging the question. The Shuffled code might be solvable without any other cards, but they don't seem to say that information on other cards will not help. It just tweaks my clue-o-meter that they would go to all the trouble to create a meta-puzzle that gives us a whole deck of cards with 2 jokers and -not- use their order somehow.

I just noticed that the app does not let you change the starting order of the deck before keying - you can either key, or type in a whole deck. The start order for the Motor deck is (face up) joker (coloured),joker (mono), A-K diamonds, A-K clubs, A-K hearts, A-K spades, rather than the traditional bridge order for Solitaire. I don't know if this is significant, as if Garnet knows about Solitaire he might know to re-order the deck in bridge order anyway.

Possibly closed one line of investigation.

I believe I've confirmed that the playing card order (defined by the prime numbered puzzle cards) has nothing to do with Shuffled. (I know Mind Candy said we didn't need other cards to solve the puzzle, but I decided to test in case of alternate solves, or in case they were twisting the truth.)

Decryption tool used:
http://cif.rochester.edu/~la002k/solitaire.htm#fields

Playing card order used:

Spoiler (Rollover to View):

47, 7, 33, 6, 12, 21, 40, 11, 52, 20, 46, 19, 22, 50, 9, 26, 51, 5, 32, 45, 34, 10, 14, 8, 18, 44, 4, 24, 35, 13, 31, 17, 25, 48, 38, 27, 16, 30, 43, 39, 36, 23, 42, 3, 29, 2, 1, 53, 15, 28, 41, 54, 49, 37


(Numbers determined using the Bridge order -- Clubs, Diamonds, Hearts, Spades.)

Tested the text on the card, both with and without the text written with the disappearing ink. Also tested playing card order backwards. Did not extensively test anagramming or single character substitution.

I decided to post this in case anyone had any doubts about what Mind Candy said, plus it's nice to have the card order written down in case there is a Solitaire cipher I'm not aware of. Smile

I hope maybe somehow I've managed to nudge someone toward the answer. Good luck, folks!

Thank you for excluding the other cards as needed! A solution must be at hand Wink

Just wanted to mention that the bar "Five of Cups" can now be seen on the map:



Although it seems to have been destroyed... Shocked

PS. I believe its on "Translation Approach" (streetname).

Is it possible to work out the card order from reverse? if you know what the key stream was to encipher the plain text ie:

assuming that the plain text starts THE... then using the solitaire cipher method the keystream would be CTW. Is there any way of getting the card order to get that initial keystream?

No, not really Oli. The Solitare Cipher has too many different combinations to do that. Say if we get the number 21. First of all, that can be one of two cards 9 of Spades of Diamonds, but we do not know where in the deck it is, the positions of the jokers, and the top and bottom cards. This is a really hard card man! And we don't even get a hint (Watch Ask Mind Candy) I wish we did, this card may be really hard. But to tell the truth, I think that the 2 messages encoded with the same keystream seems that the only logical path to take, then we are reduced to a polyalphabaic solution! Awesome, if i have time I'll totally get on that

I think it might be possible to reconstruct, but only if you had a very long bit of plaintext. This would cut the combinations themandotcom refers to down considerably. It would be a lot of work though, and we don't have a long bit of plaintext.

More Potential Leads

I think I may have found a couple more trains of thought to follow. I've been plugging names in left and right into the Mikesroom Shuffled Decoder [mikesroom.org] (XAWHU hasn't been changed to XAWJU, so you may have to do that manually if you use this), but still haven't gotten a readable result.

-Information Theory. This has been mentioned before. Entropy is a term used in information theory; though I'm a little too thick to figure out exactly how it is used. If you want a basic resource on information entropy, you may want to check out the Wiki article on Information Entropy [wikipedia.org]. I mention this because I'm not quite convinced this lead has hit a dead end quite yet.

-Constantinus Tsallis' ideas on generalized entropy. From what I understand, Tsallis' formula explains the rare occurrences in nature, such as tornados or fractal behavior, by showing that these occurrences grow more probable as some of the conditions begin. The only article I've read so far can be found here [santafe.edu]. This might be another dead-end, so feel free to trout me all over the boards, I'm just trying to get people thinking. Hopefully it's an interesting read, at least!

My approach to both of these is trying to find cases in which entropy doesn't necessarily win. Hopefully we won't be left cold much longer.

I've been working with the idea that the garbage that comes out from an unkeyed deck is actually correct, but still encrypted.

During the decoding process I have picked out some words that have appeared but no real actual sensical phrase or full sentence, just occasional words.

including :- served, scared (I think it was) and a couple of other I don't have to hand.

I'm trying a monoalphabetic cipher to try and decode it, but no results from that till tomorrow.

Tried viniegre (sp??) and simple caeser ciphers but they output nothing.


I was wondering if reversing the text string before decoding gives anything? I have also noticed that breaking up the text before deciphering can give some words back out, this is becuase the website I used to decode the text string will convert blank spaces (incorrectly of course) but this does produce some usuable words, although not a whole sentence.


Of course if someone has already tried something like this in the 80 odd pages that make up both these threads (which I have tried to read over at least a week, so probably forgot some of whats been tried) then please feel free to send me a free fish lunch Very Happy

Yeah i thought as much! So basically we either have to punch words in to the box and hope or work out where the two messages are. maybe the letters themselves are shuffled, or the groups, either way i dont think that MC would have designed the card to be solved by trial and error. there has to be something in the card to point us in the right direction.

Quote:
Various Solitaire implentations are available here:

However, it's your job to figure out how the key is buried in the phrase.

Good luck,
Bruce


this could mean the phase whispered to him or the ciphered text. the thing that strikes me is the way it says "how the key is buried". this implies that the key is there and probably staring us in the face. Its gonna be one of those ones we all shout at the computer when we get the solve...

Not necessarily BBuck. All a polyalphabaic solution is is different alphabets that are added together. No plaintext required (thought recommended.) Techincally this is a chosen plaintext attack..

In this case, the WBBMC... is being subtracted to IF ENTROPY... This works because:

A+K=C -and-
B+K=D
so using matrix/ systems of equations
A-B=C-D

Thus if this major, major assumtion is the two messages are in fact encoded with the same exact keystream. We have to find the index of coincidences for it. (See http://tinyurl.com/qdw8e) Not too bad, and I'm sure there are programs, and programmers (CHIMERA! *COUGH COUGH*) to find it. As Bruce Schniner says, (paraphrasing) It is not hard to break after that. Now someone has to sit down and subtract all those numbers, or better yet find/make a program to do it. Then we can really tell if this card is really hard or not. But it is interesting that Bruce said "Buried in the Phrase" has Mind Candy contacted him? This I do not know. My guess would be no, they had no reason to what so ever. But I may be wrong of course, if I am, then this is one heck of a card that may be impossible w/o another hint. Stupid Mind Candy!!
