1) Normal Sudoku Rules Apply.

2) Arrow Rules: Digits found along an arrow must sum to the total in their corresponding circle or pill (read left to right). Digits may repeat on an arrow if allowed by other sudoku rules.

3) Anti-knight Rules: Two cells seperated by a chess knight's move cannot contain the same digit. (i.e. The digit in r5c5 couldn't appear in r3c4.)

4) Kropki Rules: Digits connected by a white dot must be consecutive. (No black dots are given.) Negative constraint does not apply.

I am really really happy about the opening idea in this puzzle! For the best experience, try your best not to guess-and-check particularly at the start.
