Hello.
Normal sudoku rules apply.
Digits are grouped into modular sets:
mod 1 → {1, 4, 7}
mod 2 → {2, 5, 8}
mod 0 → {3, 6, 9}
Cells with the same relative box positions must come from the same modular set. For example, if the first cell of box 1 contains a 5, every first cell of each box must contain a digit from {2, 5, 8}.
Digits in a cage sum to the total given in the top left corner of the cage.
Have fun.
Solution code: Row 9, first 6 digits.

I read the rules, then proceeded to spend 12 minutes wondering why my entropy coloring wasn't doing anything, only to re-read the rules and start back over to solve it in less time than I spent on my imagined entropy puzzle. A very smooth solve, if you read and follow the rules!
