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
