UKSpycatcher that was very nice of you to spend your time and energy to take the idea of Daishi45 about the 246 and illustrate it as well as you did. Jarlve was also nice enough to use his time to take the few lines Daishi45 gave on his proposed 340 solution and input them into the webtoy and post the results. TheForeigner also came up with a good idea to give the secrecy he wanted and I implemented her idea by creating a thread for code work that is viewable by members only, not the general public. (See
viewtopic.php?f=107&t=2244 ). I think when members new or old post work and UKSpycatcher, Jarlve, TheForeigner and others take the time to offer constructive criticism, helpful suggestions, do additional research or illustration of ideas, it reflects well on what a great resource this board can be.
Daishi45 has not yet posted in the secret thread I created for him, or posted more on his proposed 340 solution. He does not seem to want to avail himself of the resources of this board by posting his solutions. If that remains the case, I for one am not going to respond to only vague clues, so I will likely not post much more on any of his threads, unless he posts his actual solutions. But because he made a bold claim about the map code, I did some follow up research to look at what he suggested were clues on the inside of the Halloween Card. First he suggests that Z putting 3, 6 and 9 on the map is a clue. OK I like that, as Z did not use N, E, S, W as we might expect, or 90, 180, 270, 360. (I myself thought that the 3, 6, 9 and many 66's on the map could be clues to Caesar shift numbers). But he says the 3,6,9 clue is not to their combined value of 18 or 180 or 369 or 36 or 69 or any combination thereof. Rather it is a clue to 246. Hmm, not really feeling that one, but lets go to what he claims are the clues on the inside of the Halloween Card.
Daishi45: Can you further find 246 on the back of the card? In the eyes on the inside of the card? He couldn't be TOO obvious with his clues, he had to make them somewhat difficult.
Does the eye cluster in the lower left corner look kinda like the shape of a 4 if you trace a four through them? Try it. Do the eye cluster to the right of them kinda look like a six facing southeast pointing towards the return address symbol down there? Does the upper eye cluster look kinda like a 2 with no bottom line? He couldn't be TOO obvious, so he had to muddle perfect images somewhat. That's MY read on them, anyway. The reader will have to decide for themself if it feels right or is off the mark...Cheers!
AK Wilks: I was curious so I followed up on this clue. I have seen many people come forward over the years with proposed solutions based on "seeing" hidden clues that they then apply to the codes. In most of these cases there is no indication from Z that in order to solve the particular code we have to turn to the Belli letter or the Halloween Card or whatever. And in most of these cases what the prospective solver claims to "see" is highly subjective and open to suggestion. The 408 code was precise. It leads to one and only one correct solution. It did not use hidden meanings from other letters, secret messages in hidden shapes or anagrams. But I decided to take a quick look at this clue.
I don't see anything at all like what Daishi45 says he sees. Here is the inside of the HC. I wrote in red the numbers that he thinks the eye images suggest. You can look for yourself and determine if you think Z was sending us a numbers clue in these images.

First if I was thinking Z was giving a numbers clue in the HC, I would first look at the 3 fingers of the skeleton and the 14. 3.14 or Pi. Looking at the eye clusters, in the bottom left are 5 eyes, above it 3 eyes and 1 eye in hole, so either a 3 and a 1, or a 31, or just 4.So there are any number of ways to come up with numbers from this card. None of them are the 246 he suggests.
Specifically he says the bottom left looks like the shape of a 4. OK I can somewhat see that, with that suggestion in my mind. The eyes form a cross, and if you trace an outline of a 4 on the eyes, yes it does look somewhat like a 4. Again there are 5 eyes there, so to me I get the clue of 5 most strongly, but at least I do see how the shape of these eyes could be reasonably construed as a 4.
Now in regards to the upper left cluster he says it kind of looks like "a 2 with no bottom line." Wow. OK. Not seeing that at all. At all. They are somewhat in a curve. I don't see how you can say that it looks more like the top of a 2 anymore than it looks like the top of a 3. Actually to my eye the whole upper left cluster number wise looks most like an outline of a 9. If Zodiac's challenge was to actually have police break his code and go to a location where a bomb, other evidence or a taunting letter was buried, I don't see how Z, who was so precise in his first code, would think that people would look at that eye cluster and go "Aha! It is a 2." Or that people would look at that and only come up with the top half of a 2, as opposed to the top half of a 3, or it looking like a 9, or going by the actual number of eyes coming up with 4 or 3+1 or 31. As for the 4 eye cluster at the bottom and to the right looking like a 6, sorry I don't see that at all. I don't even see how anyone could reasonably claim it looks like a 6 or any part of a 6.
I don't know if this was all a joke or a prank or what. Unfortunately we have seen many of these types of solutions offered over the years. I try to keep an open mind and always think even an unorthodox solution is worth taking a look at, as it may have something of value. If not, it is worth looking at to point out pitfalls and blind alleys to help the purported solver and others avoid months and years of wasted work and time chasing false clues and failed solutions. If they persist that is up to them. I did my best.
If Daishi45 or anyone has some code work that reveals a specific location or the name of a living unconvicted person they can post it in the secret members only thread here:
viewtopic.php?f=107&t=2244 . If Daishi45 or anyone has proposed solutions, we want to see them, and you will get the benefit of the members here who are very knowledgeable in codes, computer code breaking and many other areas. What we do not want is people who claim to have solutions but won't post them, and only offer vague clues that are entirely subjective and essentially meaningless. For work and clues that are posted you have to be ready to receive polite but substantive criticism and questions. I hope this helps anyone who relies on hidden meanings to see how they are just too subjective to be part of any verifiable code solution.
