Oh, Oh, Oh, It's... (You Know)

RULES:
Normal sudoku rules apply.
Region sum columns: Each column is a region sum line (box borders divide the column into segments with equal sums).
Entropic rows: Each row is an entropic line (every set of 3 horizontally adjacent digits must have one low {1,2,3}, middle {4,5,6}, and high {7,8,9} digit).
Little killers: Digits along marked diagonals sum to the indicated value.
Digits in grey circles are odd.
The grid is covered in fog. Placing a correct digit in the fog may clear some of it.
Solution code: The last 3 digits you put in the grid (probably) from top to bottom.

40 minutes. No idea what the solution code is though.

This puzzle is clever (and funny, at the end xD), the logic was simple but not intuitive I think. if I just didn't forget about the entropic rule extending past boxes, I would not have wasted more time. Thank you for sharing this! :D

Fun puzzle, but the solution code was not actually the last three digits I entered. Tracing back, the middle one from the solution code was in fact the 12th digit I entered.

Would love to know your solution path! (In a hidden comment of course :))
