Rules:
Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.
Killer: In cages marked with a black dashed line digits must not repeat and have to add up to the total given in the top left corner of the cage.
Renban: Digits on a purple line form a set of consecutive, non-repeating digits in any order.
Entropy: The low digits (1, 2, 3), middle digits (4, 5, 6) and high digits (7, 8, 9) are defined as three different groups. In the finished grid each 2x2 box has to contain at least one digit of each group.
Have fun solving!
Solution code: Row 9 followed by column 5 (18 digits)

Very fun puzzle. Great logic until the very end (which kind of felt like a step up in difficulty from what came before).

Another masterclass in setting. Amazing craftsmanship.

Thank you for this great entropy puzzle, Mad-Tyas! I especially liked the interaction with the renbans. I have to admit I got stuck at some points of the solve, but the deductions I found then always felt completely fair. Thank you for setting and sharing!

I need to find me a partner who loves me as much as Mad-Tyas loves entropy.
Lovely puzzle, thanks for taking your time to set it!

@ Qodec: Sure this is a smile? Rather felt like an evil grin to me, especially when I spent ages finding the last step to finish the puzzle ... ;-)
