The title of this puzzle isn't meant to be sarcastic - it was designed to introduce a few global entropy mechanics that I enjoy.

Rules:
- Normal Sudoku rules apply.
- Global Entropy - every 2 by 2 box of cells in the grid must contain a low digit (1, 2, or 3), a middle digit (4, 5, or 6), and a high digit (7, 8, or 9).
- Modular Lines - any set of three digits in consecutive position on a teal modular line must contain a digit from the set (1,4,7), the set (2, 5, 8) and the set (3, 6, 9).
- Palindromes - the full string of digits along a thin gray palindrome line must read the same backwards and forwards.
- Killer cages - digits inside a killer cage must not repeat and must add up to the value in the top left corner of the cage.
- Kropki dots - digits separated by a white Kropki dot differ in value by 1; digits separated by a black Kropki dot have a ratio of 2:1. No negative constraint.
- X pairs - digits separated by X sum to 10. No negative constraint.

Lovely setting, thank you!

Suggestion: remove the teal lines entirely. The puzzle solves exactly the same way without them. I made a mistake and used them as entropy lines instead of modular lines. And indeed you can prove without lines at all that they must function as entropy lines as well. And the puzzle still solved pretty easily without using the fact that they happen to also be modular.
