# Solving A Numeric Cipher Where Numbers Replace Letters

I think this code is my masterpiece- let's see what you think:

159368358147349358267359259267348169367149159248348147168169147268349259149267168367147359358169257269347158269159257257358249259168358147349358

In all seriousness, though: I came up with this cipher recently to test a friend of mine who claimed he was good at cryptography, with the solemn promise that it had a solution. He still hasn't found the solution, even though he (as well as you, I bet) has already seen it before. It is one sentence, in English. I don't really know that it's my masterpiece, but I imagine it's good enough.

• Have you seen Code Puzzles: What Not To Do? This seems to me to be the exact type of puzzle that those guidelines warn against. I've found a pattern, but I've now reached the "throw spaghetti at the wall until it comes up English" phase, and that's not particularly fun (or clever -- security by obscurity is easy).

• I added a bit more information that should make it easier to solve. I still don't know if it's up to the standards in your document, but I think it's better. Commented Feb 24, 2020 at 23:13
• Knowing specific details about the solution doesn't help solve it -- the problem is that there's no real indication of what to do, so it ends up being "just try random things until English comes out". It's easy to make an impossible puzzle -- but "guess what I'm thinking" isn't a fun puzzle at all, and that's what this looks like it might boil down to.

• I understand and respect your criticism, but it's not just that I gave a specific detail- I actually rot13(tnir gur fbyhgvba va gur dhrfgvba) with that detail. If you were to spot that hint, then the puzzle becomes more verifying the answer. Commented Feb 25, 2020 at 0:08
• Ah, I see -- yeah, that's a slight improvement. It makes it more solvable, at least.

- Read triplets as ternary, and take the corresponding letters of the alphabet to get the first sentence in the question: "I THINK THIS CODE IS MY MASTERPIECE LET'S SEE WHAT YOU THINK". (Spaces are not encoded.)
