Oil, Water, Kropki
(Published on 19. February 2024, 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.
Black dots separate two digits where one is double the other. Not all such dots are shown.
Have fun, leave a comment if you enjoy the puzzle!
Solution code: Row 3

Great addition to a great series. I loved the minimal number of cages here. Great fun thx.

That was fun! My first time encountering the oil and water concept, and it does some fun things for sure.
The only issue I had was that I always use orange for odd and blue for even, and orange water and blue oil is quite confusing :D

I have the same trouble as Sinuit with the colouring, so I just imagine its water and sand, with the odd, yellow, sand digits sinking below the even, blue water digits.
Great puzzle as ever! Thank you!

I love these oil and water puzzles. Thanks again for this one!
The only bad thing is: I like to color even digits blue and odd digits yellow which are also good colors for oil and water. But just the other way round. So, the hardest part of the puzzle was to decide for a color coding. :-)
