(Published on 22. July 2026, 18:29 by NoSkem)
Nonconsecutive: Digits orthogonally adjacent to each other are not consecutive.
Antiking: Digits seperated by a kings move in chess can't be the same.
Antiknight: Digits seperated by a knights move in chess can't be the same.
XV: Digits seperated by a V sum to 5, digits seperated by an X sum to 10. All X and V are given.
Thermometers: Digits along a thermometer strictly increase from the bulb to the tip.
Renban Lines: Digits on a pink Renban line form a set of consecutivedigits in any order. Digits do not repeat on Renban lines.
Nabner Lines: Digits on a yellow Nabner line form a set of nonconsecutive digits in any order. Digits do not repeat on Nabner lines.
Black Kropki Dots: Digits seperated by a black kropki dot have a ratio of 1:2. Not all possible Kropki dots are necessarily given.

Nodoku. Great puzzle, very hard to keep resisting the natural instinct to rule out some digits by row and column. The 3x3 borders probably didn't help, but no reason to complain. Cheers heaps.

Takes it a bit of getting used to the unusual rule but now I feel like an expert.

Thanks for fixing the solution code, I came back 2 days later to check :). This is an original puzzle, very nice. Thank you! I enjoyed the non-sudoku rule

The bite of a scorpion. I found the title entertaining, the ruleset slick, and the puzzle Goodliffy. Approved and appreciated.

Fixed the solution code. Sorry for the confusion. I mixed up two digits. To everyone running into contradictions: normal sudoku rules do NOT apply. If you are using sudokupad for solving you should disable the conflict checker since I couldn't figure out how to make that ignore the base rules.

A lot of people missing the "Normal Sudoku Rules DO NOT apply" line in the rules.
That said, a single instance of broken sudoku just...feels like a copout for an otherwise decent puzzle. Also, as others have mentioned, solution code is broken.

Reply: Honestly I feel like that's a fair critique. Originally this resolved to be a completely valid sudoku kind of as a joke to be honest but I felt like that was just boring so I added the one mistake. This was my first ever go at a 9x9 sudoku and I think there is definitely a lot of room for improvement in general.

It breaks in box 7 - the nabner and renban conflict

Yeah something is not right with this puzzle. I just put two 2s in a box and solution checking says everything is fine.

My solution seems correct, but solution code is not accepted

Solution code is now working. Is a good puzzle. I also neglected to read thoroughly and skipped over the Sudoku rules do not apply. I was able to eventually solve it by doubling up the two in Box 7.

I must be missing something, I keep coming into contradictions. Please let me know any advice or if anyone else is having a similar experience
