Oil, Water, Circles
(Published on 25. May 2026, 16:00 by Blobz)
Oil and Water Puzzle Pack
IV : Oil, Water, Circles
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.
A digit in a circle indicates how many circles contain that digit.
Have fun, leave a comment if you enjoy the puzzle!
Solution code: Row 1

For a novice like me (and just knowing CtC's Simons strategies without the practice of applying them) I had to restart the puzzle 3 times having missed combinations. In the end, when considering all options, this puzzle solved beautifully (if you remember all of the rules at all times :) ). Thanks!

I like how one rule doesn't dominate over the other, you have to use both together throughout.

Amazing how the rules tie together and yield a path the entire time - though I did trip up a few times. Oil Water coloring and circling and digit coloring and caging - all done so well together. Thanks!

I love this ruleset - actually odd/even puzzles in general, feels like you get two puzzles for the price of one

My favorite of this series so far! There was a point where the logic really clicked for me and it made the rest of the solve so much more fun. Really clever construction on this one.
