Oil and Water Puzzle Pack
X : Arrow Mosaic
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.
Digits along arrows sum to the digit in the attached circle. Digits may repeat along arrows if allowed by other rules.

I am a little surprised people are having a difficult time with this one. I typically have a hard time with 2 star puzzles, but this one to me felt on the very easy end of 2 stars, but still certainly not a 1 star breeze.

After reading the comments, I was a little worried whether I'd be able to solve this, but to me once I had filled in the colors, the numbers didn't just jump out, but they also didn't feel that difficult to do. Might just depend on how you look at a sudoku, I guess. Thank you blobz for another nice puzzle!

Pouring in oil and water was nice and easy. Putting in the digits was much harder than expected. Anyway, thank you for creating and sharing another O&W- puzzle.

this cannot be level 2.
working out the materials is easy enough, if you are familiar with these variants.
working out the values is not

Interesting, my solving time (20min) indicates a 2*, but one deduction by contradiction felt like 3* to me. Overall still a fun puzzle which deserves a higher rating imo, thank for setting this delightful series!

Really liked the interaction of the arrows and the oil-water constraint, took me a bit to get my head around but solved very smoothly when I finally did!
