Build Your Own Anti-Knight Sudoku
(Published on 24. October 2020, 17:41 by DiMono)
Standard sudoku rules apply.
Anti-knight rules apply: no two cells in the grid a chess knight's move apart may contain the same digit.
Numbers outside the grid intersect to reveal the locations of given digits within the grid. For example, if the clues outside rows 1 and 5 and columns 2 and 7 contain 4s, then there is a 4 at two of R1C2, R5C2, R1C7, and R5C7. In other words, the clues outside the grid combine to describe pre-defined x-wings and swordfishes. Visual example below and at solve link.
Solution code: Row 1, Column 9

Added further clarification to the rules.

To be honest, the rules are not clearly stated, and the illustrations are not described, so many people have chosen to ignore them, including me.
@cdwg2000 In what way are the rules and illustrations unclear? It's a bunch of predetermined x-wings and swordfishes.
***You just need to explain what the prompt numbers 3 9 on the left side of the first row and the numbers 2 4 8 9 on the top of the fifth column mean. Are they separate clues or interactive clues? There is no explanation in the rules. what is the relationship? What is the relationship with coordinates? What does it have to do with Anti-knight? The legend has no explanation, which makes people very confused. Instead of carrying these questions, it is better to give up.
***Again, it is not an offense!
@cdwg2000 The rules contain an explanation of that: "For example, if rows 1 and 5 and columns 2 and 7 contain 4s, then there is a 4 at two of R1C2, R5C2, R1C7, and R5C7." And the images on the right have a visual representation of satisfying a set of clues, and not satisfying a set of clues. I can edit it to say "if the clues along rows 1 and 5 and [...]" but I'm not sure what else I can do here. I am open to suggestions regarding clarity.
@cdwg2000 I have updated the rules to hopefully add clarity to them.

So sad to see this variant dropping to bottom page 3 without even earning a grade. I really liked it.
