Normal Sudoku rules apply (digits 1-9 once each in every row, column and 3x3 box).
Anti-Knight: cells a chess knights move apart may not contain the same digit.
Anti-King: cells a chess kings move apart may not contain the same digit.
Non-Consecutive: Orthogonal adjacent cells can not contain consecutive digits.
Solution code: Row 1

Very nice, but quite difficult. I would rather go with the initial 4 star rating!

Puuzles with the (quite common) combination of this ruleset are all the same - the break-in is usually a bit challenging, but after that, it only takes a minute or two to fill in the rest. I personally like the first part more than the second.

3* seems about right to me. Very challenging to place the first digit and then it all falls nicely from there.

Did take me a bit to place the first digit, but after that it was pretty smooth sailing. Closer to 2* for me, but I've also seen a lot of anti-king/knight/adjacent puzzles.
