Color me stoked! (9x9 version)

(Published on 30. July 2025, 15:57 by chrisjnap)

Normal sudoku rules apply.

Every three consecutive cells along a peach entropic line must contain a low digit (1,2,3), middle digit (4,5,6) and high digit (7,8,9).

Cells that are orthogonally adjacent cannot contain consecutive digits.

The one and only instance where a pair of orthogonally adjacent cells are from the same entropic set is shaded.

Cells in a killer cage sum to the total given in the top left corner.

The digit in the grey circle is odd.

Digits orthogonally adjacent from a 'maximum cell' are smaller than it.

So beautiful!
I normally struggle a lot or don't manage anything over 2*, but this felt approachable. Colouring the whole board was easy and then spotting how the restrictions interacted with each other made everything happen like magic!

What a nice puzzle! I've done the first version a year ago, redid it today because I forgot, and I wanted to grab a bit better all of the implications and logic of the rules. Well, that was a great idea, because it was way smoother for this one after that!
I loved how the tiny little negative constraints seems not so important but are exactly the opposite!
Thanks chrisjnap!

Coloring squared. Really cool, thanks!

What a great use of the cages to force some neat coloring logic into their regions!
Depended on a secondary coloring at least 2 or 3 times, and had a great time following the logic.

Right from the get-go, I had a gut feeling on what the odd digit was going to be, but it was fun proving that right xD

Thanks for setting!

What a fun puzzle! I missed the non-consecutive constraint for far too long, proving yet again how helpful it is to read all the rules. :)
Thank you for this fun puzzle, chrisjnap!
