Oil and Water Puzzle Pack
XI : Foggy Oil and Water
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 in cages must sum to the small clue, if given.
The grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues.
Have fun, leave a comment if you enjoy the puzzle!
Solution code: Row 1

Tricky break in! I usually have trouble finding where to start with these, but the fog helped guide my eye all the way through

Just over 44 minutes. What a slog. “¯_(ツ)_/¯“

My first water/oil puzzle. Been a bit intimidated to start, but figured a fog would be nice to try. Took a little bit to get my head around but all around a really fun, smooth solve. Just under 25 minutes for me. Thank you Blobz!
