Standard 9x9 sudoku rules apply.

Antiknight and Antiking: Any two cells separated by a knight's or king’s move in chess cannot contain the same digit.

Nonconsecutive: Any two orthogonally adjacent cells cannot contain consecutive digits.

Quadruples: Digits in white circles must be present at least once in the cells the clue touches. If a digit appears more than once in a circle, it must be present at least that many times in the cells the clue touches.

That was a bit too easy, 1* at most. Wonder if that's the reason for the low rating?

Very clear with what digit to start with.
I like that you know if you can get it going you will be able to finish it because it is easier as you place digits, true "Miracle Sudoku" style.
Anyone needing help to break in can turn on "show seen cells" in Sudokupad. You just select the candidate positions in one box and it highlights how many other cells are seen and can't have a digit that would conflict.

I’ve solved each puzzle you’ve posted on LM. I enjoyed them all and feel you have been unfairly rated here. Your YouTube video for the last puzzle is great, and I used you coloring technique on this puzzle. Thank you,

I liked it a bit less than most of your other constructions, because the beginning is probably more like a two star, then almost everything else was an absolute cakewalk. I prefer when puzzles keep up a similar challenge level throughout.

For me the break in was slow but then it was fun
