Factorial Cages
(Published on 13. August 2024, 10:48 by Nurator)
This puzzle got inspired by the Fundamental Theorem of Arithmetics. The rules are short, but there is depth to be found if you look carefully :) My first 5 star puzzle, so hopefully you have as much fun solving it as I had setting it.
Rules:Normal Sudoku rules apply.
Digits in cages multiply to N factorial (N* (N-1)* ... * 1), where N is the size of the cage. Digits may repeat in cages, if allowed by other rules.

Astounding puzzle! This took me a long while and it's one of the hardest I've ever solved, but it's really satisfying. There are many great aha moments. The geometry of the cages is cleverly designed.

Really nice puzzle with a lot of math which I don't mind. But I think is 5 stars instead!
