Normal Sudoku rules apply.
Cells one chess knight's move apart may not contain the same digit.
Diagonally adjacent cells cannot contain the same digit.
Digits in a red cell in column X indicate the position of X in its respective row.
Adjacent digits on a green line differ by at least 5.
Solution code: Row 1 no spaces

The wording of the anti-king rule made me pause and spend some time proving to myself that it is in fact the same rule.
159 is by far my favourite ruleset so this one was really easy, but enjoyable nevertheless.
May have to try this with just that one line.

yeah.. kinda nice.. unfortunately once you seen the pattern the anti-knight anti-king combo creates, it's a bit dull;
it's always the exact same coloring pattern rarely flipped or rotated, still enjoyed it

This is how you set a puzzle!

Gosh. That was a surprising break-in. Very beautiful. I'm glad you kept the two lines because it let me enjoy the break-in twice ;)

"Diagonally adjacent cells cannot contain the same digit".... cant anyone say anti-king as before instead of creating new sentences for things that already have a word for it ???

I'd have changed the wording of knight's move as well if there were a more succinct way of wording it. I understand what you're saying and part of me agrees, but I'm a fan of rules being in as plain language as possible. - mellow

Wow, indeed. What an amazing setting for a fully 1-star puzzle. And the solution popup answered a question that had already crept into my brain. Amazing work!

Absolutely beautiful! Well done. I love when an easier puzzle can still be elegant and well designed. Nicely done.

no, i don't believe it. but i UNDERSTAND that it took serious study of the 159 structure to FIND this result, so i will TRUST you. IMPRESSIVE.
sudoku bar bet: place 4 green sticks on this grid to solve it. will win lots of beer.

Yeah I've been obsessed with German whispers and 159, how 46 and 19 play is super cool to me. Stumbled on that little V whisper shape, there were some iterations with several of them about. Then I added antiknight & antiking for fun and it was so restricted I couldn't find anywhere that the lines could work in the way they were in previous iterations. So I decided to start with just the bottom right line, and that's when the computer told me the solution was unique. Mind blown but I couldn't solve it by hand. So I put in the second line with the computer solution as reference and found it was a really nice solve. It feels almost more like discovery than setting - mellow
