- Normal sudoku rules apply; marked diagonals also contain the digits 1-9
- German Whispers: Digits adjacent along the green line must differ by at least 5
- Negative XV Rule: Orthogonally adjacent cells may never sum to 5 or 10
- Quads: Digits inside circles are found somewhere within the four surrounding cells
Solution code: Column 4 and Column 6

Very challenging for me as a beginner, but got it in the end. There were several times I wanted to give up, but chose to keep pushing. Probably the most rewarding solve for me personally, thank you very much!
REPLY: Well done on persevering! Glad you enjoyed it :)

Not sure if I followed the intended solve path, but I found this a bit tough and had to dig into my bag of tricks

I really enjoyed the back-and-forth among the constraints. At times it seemed like there was not enough information and then I'd see an X-wing somewhere or a pair that needed to be kept apart. Thank you for setting it.

Found it difficult for me. The Negative XV Rule made me keep thinking about non consecutive for some wierd reason. I have made some mistake initially as I ended up with 7s being forced in box 7 in row 9 and 7s forced in box 9 row 9 as well. Fully reseted and tried again succesfully.
