Rules:

Irregular Sudoku rules apply. Place the digits 1–9 once in every row, column, and marked region.

Anti-Knight: Cells separated by a knight’s move in chess cannot contain the same digit.

Kropki dots: Cells separated by a black dot must have a 1:2 ratio. All possible dots are given.

Little killer: Digits along marked diagonals sum to the number indicated outside the grid.
