Rules:
Place the digits 1-9 in every row, column and irregular box.
Antiknight: cells separated by a knight's move in chess cannot contain the same digit.
Global Modulo-3: every 2x2 square of cells must contain a digit from (1,4,7), a digit from (2,5,8), and a digit from (3,6,9).
Global Non-consecutive: cells that are orthogonally adjacent cannot contain consecutive digits.
Little Killers: digits along marked diagonals sum to the number indicated outside the grid.
Parity: cells with a circle must contain an odd digit.
Love, Brigitte
Solution code: Row 1 from left to right (9 digits in total)

Very clever and very quick once you see the trick. The best part was a certain thing happening twice simultaneously when I bulk-filled a certain digit :)

Definitely a 2 star rating. Really liked it.

This is great. Only got stuck because I forgot about the other constraints. Other than that it was very smooth solve.

Lovely and elegant puzzle! I eventually found the intended solve path, as described in the hidden comment. The challenge was finding that path after spending time exploring other options.

Very pretty! Didn't really have a hard time even though I am unfamiliar with the global entropy ruleset.

I got this puzzle recommended and it for sure did not disappoint :) quite the mix of rules but you make them go hand in hand so well, it was a very enjoyable solve. Thank you very much!

I really love your Sudokus, Brigitte. Because I'm a beginner, most of them are far too difficult for me and I need many hours to solve them. Anyway, I found this one absolutely wonderful.

Great puzzle, thanks for the hidden comment, it validates that I indeed followed the intended path. Lovely construction!

This is far harder than 2 stars. I can color the entire grid and seperate the 3 modulators. Via the killer left right, isolate on of the 3 different modulators, but then there's a complete brick wall. Consecutivity rules also doesn't help do to the layout.
Eventually I just gave up and cycled through the 3 remaining combinations to see what fit. Don't like trial and error endings.
Br1: I'm sorry this was a frustrating puzzle. I really hope you didn't forget about the antiknight rule. I made a hidden comment with the intended solve path, if you want to compare.

in order to qualify for level 2, there needs to be something to "bite on". here, you can colour a couple cells, and then it's a brick wall
Br1: I don't want to give spoilers, but perhaps this is something more people struggle with. You can colour in the modules very easily. I can see this puzzle being frustrating if you pick the wrong colour strategy, but if you pick the right one, it's really not that difficult.

Terrific.
