Normal sudoku rules apply, with the addition of the following:
Thermometer: Digits rise along each thermometer, starting from the bulb.
Anti-knight: The same digit is never a chess knight's move apart.
Diagonal: Both marked diagonals hold the digits 1 to 9 once each.
Solution code: Enter the digits of row 1 (left to right).

loved that! it felt like periods of careful anti-knight pencil marks, followed by all of a number being filled in ~~ very nice payoff

This is the first “3*” I’ve done. I genuinely feel amazing I had to colour it at the end, the most fun I’ve had doing a puzzle. Took me a while tbf but props to this setter.

I liked it a lot how diagonals and thermometers complemented anti-knight rule so it became really powerful. Very enjoyable puzzle.

Definitely qualifies as a REAL anti-knight. Great construction and execution. Well done.
