Harmonious Thermos

(Published on 30. January 2025, 19:57 by sujoyku)

This puzzle has been set for one of Scojo’s recent Setting Saturdays prompts and uses a slight twist on the normal thermometer ruleset. I like to thank all testers and wish you joyful solving!

- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.

- Harmonious Thermometers: Digits along a thermometer must strictly increase from the bulb end. Additionally, the sum of the digits along a thermometer must be divisible by its number of cells. For example, if a thermometer consists of three cells, the sum of its digits must be a multiple of 3.

Thank you for a lovely puzzle. I'm not sure whether I may have missed something at the beginning however as the break in (at least, my break in) felt much harder than 2 stars. After that however, all the logic flowed beautifully.

You are much welcome, Hamsterbase, thank you for your comment! It is great to hear you liked the puzzle. Concerning the break-in: In my opinion, it is the hardest deduction of the puzzle. To avoid spoilers, I have described my intended break-in logic in a hidden comment.
Kind regards, sujoyku

Wow! Absolutely stunning minimalistic puzzle! Even after solving it, I can hardly believe this has a unique solution. Thank you Sujoyku for sharing this gem.

You are much welcome, Paquet Voleur, thank you for your comment! I am glad you enjoyed the puzzle. The little extra in the thermo rules has quite some impact allowing for relatively few clues.
Kind regards, sujoyku
