Kropki XV
(Published on 12. January 2021, 23:50 by abed hawila)
An XV variant sudoku without XVs!! Let us see how it goes.
Rules:
Normal Sudoku rules apply.
Standard Kropki rules apply. All black and white dots are given. (negative constraint apply)
Standard XV rules apply. All Xs and Vs are given. (negative constraint apply)
Note:
Negative XV also applies on Kropki dots, meaning that two consecutive digits cannot share a Kropki dot if they add to 5.
Solution code: row 8 row 9 (18 digits, no spaces)

Very nice, thanks for sharing. Figuring out final ”lock” took a while with so many negative constraints. Thread carefully or it will end badly, ask me how I know :)

So satisfying, yet again! The first breakthrough was cool, but the negative constraints really made for such interesting and engaging solve till the very end! :)
