NKSA W06: Christmas Trees
(Published on 24. November 2025, 06:51 by schumaster)
This is the sixth puzzle of the NKSA Weihnachtskalender. The last three puzzles starting with this one should be around the 1* difficulty of LMG. 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 2:1 ratio. Digits in cells separated by a white dot are consecutive. Not all dots are necessarily given.
XV-Dominos: Cells separated by an X must sum to 10. Cells separated by a V must sum to 5. Not all Xs and Vs are necessarily given (no negative constraint).
German Whispers: Adjacent digits along a green German Whispers line must differ by at least 5.
Solution code: Bottom row, left to right

I typically solve a 1 star puzzle in 30 minutes, this one took me 8. Great snack!

Background image moved. Let me know if the restrictions are still there. Thanks for the comments on this.

I used an Irish VPN to get round the Imgur block

Really hard to see any pencil marks as background "Content not viewable in your region".

Word of warning:
Imgur is blocked in the UK, so we get a "Content is not viewable in your area" placeholder, with a blue background that is almost the same brightness as pencil marks, making them almost impossible to see.
Yes we can use SudokuPad's settings to hide custom colors/images, but figured I'd flag it up anyway since using another image host in the future may solve the issue and let your pretty work shine without us needing to erase it!
