NKSA W05: Rudolph
(Published on 22. November 2025, 16:18 by schumaster)
This is the fifth puzzle of the NKSA Weihnachtskalender. It was created in the Impulswoche Mind-Benders 2025. Have fun and leave a comment.
Rules:
Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box.
Kropki pairs: Digits in cells separated by a black dot are in a "Number in the dot":1 ratio. E.g. a 3 in a black dot means, that the digits in the adjacent cells are in a 3:1 ratio (1-3, 3-1, 3-9 or 9-3).
Digits in cells separated by a white dot are consecutive. Not all dots are necessarily given.
Adjacent digits along a Dutch whispers line must differ by at least 4.
Digits on Thermos are strictly increasing from bulb to tip.
Solution code: Bottom row left to right.

Enjoyed the snack greatly, thanks. Even ignoring the Dutch whispers line it only took me 15 minutes.

Note on the rules: a 3-dot would also allow 2-6 and 6-2
