Normal sudoku rules apply: place the digits 1 to 9 in every row, column, and 3x3 box.

Arrows: Digits along an arrow sum to the digit in that arrow's circle. Digits may repeat on an arrow if permitted by the other rules.

Kropki: Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Not all dots are given.

Lovely! I really enjoyed the flow of solving this, and the way the arrows all running parallel worked together.

Curious to know if anyone solves this, I've tried it 3 times and it seems to break each time, could very well be an error on my end though.
