I’m a novelist, not a mathematician. But I designed a logic-based cipher for a story that turned out to be... brutal. No XOR, no primes, no RSA. Just addition, subtraction, and the periodic table.

It’s not a math problem. It’s a sequential logic ritual:

    Miss one step, and you get garbage.

    Guess the rule order wrong? Total failure.

    Even with the full message, decryption is impossible without the correct rule set.

Every AI I tested—GPT-4, Claude, Grok—failed to break it. Grok imploded after a dozen clues. The kicker? It uses only public references: the periodic table and the current date.

Here’s one of the encrypted strings:

71 50 49 63 102 65 70 126 61 64 52 112 117 56 57 141 80 51 58 125 93 @ElonMusk 92 167 55 94 62 66 68 6 10 25 DECRYPTION CODE: 1313 First 3 words (verified): THIS IS SIMPLE The rest? You tell me. Decode the full message, reverse engineer the system, and you win. Or—build your own cipher that’s just as logic-driven and AI-resistant.

No gimmicks. Just logic. I’ll answer questions and confirm attempts.
