Black Sheep
(Published on 29. June 2026, 16:00 by Blobz)
Oil and Water Puzzle Pack
IX : Black Sheep
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.
White dots separate consecutive digits. Black dots separate digits where one is double the other.

I was getting stuck until i glanced over at the rules and saw the standard instruction... digits do not repeat in cages. D'oh!

O&W was ok, filled in ~20 digits, but then got stuck. Turned out, I overlooked a single due to a white dot constraint... I'm blind sometimes :-)

Thank you very much for creating and sharing another lovely O&W-puzzle. Had exactly the same experience with this as Snookerfan.

Like these puzzles! Filling the cages with oil and water is fun and approachable, filling the digits was really tricky. Thanks
