Normal sudoku rules apply.
Between Lines: Cells along lines between two filled circles must have values between those in the circles. Digits may repeat on lines if allowed by other rules.
Arrows: Digits on an arrow must sum to the digit in the circle.
Kropki pairs: Digits separated by a white dot are consecutive. Digits separated by a black dot have a 1:2 ratio. Not all dots are necessarily given.
Even/Odd: The grey square indicates an even digit. The grey circle indicates an odd digit.
Can be played online at F-puzzles or Sudokupad
Solution code: Row 4, left to right (9 digits, no spaces).

My first attempt at solving a four-star difficulty. Took me a while, but I got there! Thank you for creating it.

Great puzzle tallcat!
It felt like I had to use a multitude of different ideas and techniques throughout the solve. The "small" clues did a surprising amount of heavy lifting.
