Oil, Water, Arrows
(Published on 2. June 2025, 16:00 by Blobz)
Normal sudoku rules apply.
Each cage is either full of "oil" (even digits), full of "water" (odd digits), or a mix of both. In all cases, each "row" within a cage is of just one type (oil or water). Oil floats on water, so even digits will always be in rows above odd digits in mixed cages.
Digits in cages do not repeat and must sum to the small clue, if given.
Digits along arrows sum to the digit in the attached circle.

I don't know why puzzles that mix shading and sudoku cause my brain to produce so much dopamine, but I will stop worrying about it and just be grateful that the puzzles are here to solve.
