Normal sudoku rules apply: place the digits 1 to 9 in every row, column, and 3x3 box.

Anti-knight: Cells separated by a knight's move (in chess) may not contain the same digit.

Killer: Digits in a cage sum to the small clue in the cage's top-left corner. Digits may not repeat within a cage.

Solve online in SudokuPad.

Solution code: Row 2 (9 digits)

For me, a perfect 1*. A clear solve path, solvable in less than 10 minutes. Thanks for setting.

Finished in just over 6 minutes. Unless i did something wrong, i never used the anti-knight rule. And i solved the puzzle without even touching the middle three rows. ¯_(ツ)_/¯

Anti-knight was very powerful. Very fast solve, thanks. Definitely no more than 1 star if you’re familiar with the negative constraint.
