Parity Snakes
(Eingestellt am 29. Januar 2024, 19:35 Uhr von Malrog)
Rules
Normal sudoku rules apply.Digits on a white dot must be consecutive (not all dots are given).
A digit in a grey square must be even.
Each cell containing a circle is the head of a parity snake, whose length is the digit in the circle. A parity snake is a non-branching one-cell-wide path of orthogonally connected cells of the same parity, which may not orthogonally touch itself or other cells of matching parity. A snake may not have two heads, and may be a single cell.

Lösungscode: The digits in row 3, left to right.

Amazing execution of a really fun and interesting idea! I particularly enjoyed how you managed to squeeze so much logic out of the dots. Thank you very much!

You're welcome and thank you too for solving. The dots did do wonders, and I imagine other constraints could also play well with parity snakes.

Really enjoyed this - some interesting clue combinations and logic and it didn't just collapse into odd/even for the Sudoku part.

Thank you, I'm glad it's interesting all the way to the end! I do feel like there's plenty more mileage in parity snakes, if anyone was so inclined to try.

Absolutely loved this puzzle! It was really cool how the Kropki dots were so useful in both snake logic and the final disambiguations.

Thank you, I really appreciate the kind words. This variant combination was certainly fun to set with.
