Normal Sudoku rules apply.
Arrow rules apply (digits along the arrow sum to the total of the digits inside the circle, read left to right).
Anti-queen rule apply to cells in a circle or along an arrow. A digit in such cells can't be within a chess queen's move of the same digit in another of those cells.

The cells themselves, and therefore any digits within them, are already unavoidably within a queen's move of each other. So you probably mean "Anti-queen rule apply to *cells* in a circle or along an arrow. *A digit in those cells* can't be within a chess queen's move of *the same digit in another of those cells*".
And just to be sure: A digit can see the same digit on a queen's move if one of them is not on a arrow (incl. bulb), right?
Edit: Correct, the anti-queen rule does not apply to all digits, only those along an arrow or in a circle. Updating the description based on your feedback, thanks!
