Frizz
(Published on 12. July 2025, 13:48 by Ungesundheit)
The continued dreadful heatwave in Britain has resulted in my usually unruly hair taking on a life of its own and becoming essentially a cloud of frizz. With this in mind, I have created a puzzle that is reminiscent of this.
THE RULES:
Normal sudoku rules apply: fill the grid with digits 1-9 so that none repeat within a row, column or box.
Cells connected by a V sum to 5. Cells connected by an X sum to 10. Not all Xs or Vs are necessarily given.
Entropic Hairs: Any set of three sequential cells along a peach coloured entropic line must contain a low (1,2,3), middle (4,5,6), and high (7,8,9) digit.
Modular Hairs: Any set of three sequential cells along a teal coloured modular line must contain digits with different values modulo 3 - this means one digit from each of the sets (1,4,7), (2,5,8) and (3,6,9).
Happy solving, and stay cool!

Nice interaction between the modular and entropic hairs. Thanks for the puzzle!

Just for the record, embedding a solution code in an online link means people can't solve this on paper.
Ungesundheit: the feedback seems to be equal between those who prefer the solution codes and those who prefer a string of numbers instead… I’m kind of torn personally as I find the words far easier to remember and input than the numbers but I can see the other point of view too. I’m trying to think of some way of implementing solution codes that makes both sets of people happy- I think there might be something clever I could do with letter-based puzzles on that front. Thanks for the feedback though, it’s really helpful to know what people actually prefer :)
Qodec: Didn't like the puzzle any less for it, enjoyed it a lot!
