Killer Binairo (With a Little Algebra for Good Measure!)
(Eingestellt am 5. Dezember 2021, 01:35 Uhr von mathpesto)
I set out to create something more challenging than my previous binairo variant, and more challenging it is! I had a lot of fun constructing this and I hope you have a lot of fun solving it. Comments and ratings are much appreciated, and please be sure to check out my other puzzles here.
Rules:
Normal sudoku rules apply.
Five of the digits 1-9 belong to Set A. The remaining four digits belong to Set B.
Binairo: No more than two digits from the same set may be adjacent in a row or column.
Killer: Digits in a cage cannot repeat. Each cage has two number clues: one of the clues is the sum of the digits in the cage that belong to Set A, and the other clue gives the sum of the digits in the cage that belong to Set B.
Some clarifications:
The order of the clues in a cage doesn't necessarily correspond to A first and B second.
"x", "y", and "?" represent non-negative integers. The value of the "?" is not necessarily the same among all occurrences.

Great puzzle with some sneaky deductions, all I'll say is read the clues carefully!

Does greater than eight mean that it's just 9, or could it be 8 or 9?
--------
@AppleSaws, strictly greater than 8, so it cannot equal 8. -MathPesto
