Grecian Computer Puzzle

This is the Grecian Computer Puzzle — a really tough one!It’s made of five rotating rings, and if you look from the top, each ring has 12 numbers. Some parts of the rings are cut out so you can see the numbers underneath.The goal is to turn the rings until all 12 columns add up to 42.A lot of people online have tried solving it by writing code to brute-force it. They found that out of 20,736 possible combinations, there's only one solution.The puzzle is based on math concepts, but I couldn’t find clear info about the designer. There’s just a mysterious story that it was inspired by a strange device found in a shipwreck near the Greek island of Antikythera back in the summer of 1901.And the number 42? It reminds me of The Hitchhiker’s Guide to the Galaxy by Douglas Adams. In the story, a super-intelligent alien race builds a giant computer to find the ultimate answer to life, the universe, and everything. After 7.5 million years, the answer it gives is… 42.
