NKSA W08: Get Snowed!
(Published on 26. November 2025, 17:23 by schumaster)
This is the final puzzle of the NKSA Weihnachtskalender. The puzzle was created in the Impulswoche Mind-Benders 2025. Have fun and leave a comment.
Rules:
Chaos Construction: In every row and column, each digit from 1 to 6 occurs exactly once. In addition, there are 6 continuous regions in which each digit from 1 to 6 occurs exactly once. The shape of these regions have to be determined by the solver.
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).
Region sum lines: REGION borders divide each blue line into segments with the same sum. Every Region sum line is split by a region border at least once. (No full region sum line in the same region).
Snowflake Kropki Dots: Digits in cells separated by a Snowflake are consecutive. SNOWFLAKES INDICATE REGION BORDERS. Not all snowflakes are necessarily given.
Solution code: Digits of the region containing the bottom right cell (r6c6) in reading order.

Very nice! Approachable but challenging. If 6x6 has its own rating system this would be a 3* difficulty but for all sudoku i agree with the 1*. Thanks for the “beginner” friendly CC

Snowflakes are visible for me, so I assume the problem is fixed.
I had a hard time finding the regions, and got stuck for a while about 1/3rd of the way through finding the numbers, so I gave it two stars, but it’s a terrific puzzle, enjoyed it quite a bit.

The fondue warmed me up for the pretty winter scenery. Lovely puzzles both.

Always great to see an approachable chaos construction puzzle. I share Welgen's complaint, though - regardless of whether "emoji replacement" or "hide background image" are on or off, the snowflakes have all melted.
Luckily, some x-marks with the pen tool help solve that; it would have been a real chore to have to flip back and forth.

Very nice!
The snowflakes are missing on sudokupad though.
// maybe you have the background imgs disabled?
Ah yes, that fixed it. I forgot this option even existed.
