When It's Time To Parity We Will Parity Hard (with Calvinball)
(Eingestellt am 24. April 2025, 13:16 Uhr von ChinStrap)
For our first collaboration, Calvinball and I combined index lines and parity mirror. Thanks to all the testers!
Rules:
- Normal sudoku rules apply.
- Parity Mirror: The diagonal from r1c1 to r9c9 acts as a parity mirror. Each cell has the same parity as the cell reflected in the mirror, for example if r2c6 is even, r6c2 is also even.
- Index Lines: The digit in the Nth cell along a teal line (starting from the diamond) indicates the position along the line where the digit N appears. For example, if a diamond cell contains a 3, the third cell along that line must have a 1.
All feedback (positive or critical) appreciated!
Lösungscode: Column 9, top to bottom (9 digits)

Fun one! The symmetry that you manage to induce with asymmetric lines is particularly inspired. Very cool logic involved. Thank you!

Wach small deduction seemed irrelevant at first, but then I realised how it kept things moving. Amazing puzzle.

ChinStrap, we need to talk about your addiction to Index lines... I'm your friend and I'm worried about you. Please, reach out to someone before they take over your whole life.
As for the puzzle, it's fabulous. Of course it's fabulous, it's made by two of the most ingenious setters around. You do have to walk the straight and narrow when solving this but once you see the way forward it all flows really well.

Lovely puzzle! Some deductions were quite hard to figure out, but all of them were beautiful. Thank you, ChinStrap and Calvinball!
