Knightly Nine's Killer Donut

(Eingestellt am 14. April 2024, 21:48 Uhr von RaygunUltra)

Greeting once again friends. this is my second of a planned 3 torus grid puzzles that I've been working on. This one is somewhat harder than the first one (if you want to attempt my other puzzles in this set, you can do so here, Around the Torus in 100 cells, Knighted Ranged Regiments) and I'm really proud of it. I hope you enjoy. Also, I'd be very grateful to anyone who can recreate this puzzle in the CTC software so I can include a link for it later on.

Normal sudoku rules apply; i.e. the digits 1 to 9 need to be placed, once each, in every row, column, and 3x3 box.

This grid is set on a torus, and only has 100 cells. This means that row 1 and row 11 are in fact the same row. The same is true of column 1 and column 11.

Within the grid are 10- 3x3 boxes that must be found. This means that there are 10 cells in the grid that contain no digit. (Blank cells use a zero to solve uniquely)

Cells separated by a knight's move (in chess) cannot contain the same digit.

Digits along an arrow must sum to the digit in that arrow’s circle.

Digits in a cage must sum to the number in the top left corner of that cage.

If the edits are tiny (adding just a sentence or correcting some ortography mistakes) I usually delete the comment later (you can leave just one comment saying some changes were made).
To contact CtC, they have this public email in their videos: crackingthecryptic@gmail.com

How should I should I send it to CtC? I would love it if they did a video about my puzzles.

Liked a lot this one as well, but as @Smartacus pointed, it didn't seem too hard after solving the previous one. Nice construction anyway! (and thanks to @Nordy for the link)

For future puzzles you may use this webpage (I don´t know others) https://sudokumaker.app

And as your puzzles are not having too much recognition here, I reccomend you send them directly to CtC, I think they will gladly feature one of them in their channel.

Thanks for the puzzle once again. Looking forward to the third one. And thanks to Nordy for puting it into Puzzle.tv.
Doing the first puzzle certainly helped navigating the torus.
