Normal Sudoku rules apply.
Anti-knight rules apply to the digit 9. A 9 can't be within a chess knight's move of another 9.
In addition, a 9 can't be within a chess knights move of two cells that sum to 9.

I don´t understand the ruleset. In box 1 the 2 and the 7 sum to 9 and so the 9 in r1c1 breaks the rule.
edit (by tzael): The 7 is not within a chess knights move. So the 7 couldn't be in R3C2.
edit (by VeTaurus): How can a 9 be within a chess knights move of 2 cells? The 2 is within so I still don´t get it.
edit (by tzael): R1C1 is within a chess knight's move of R2C3 and R3C2. So the rule states that the sum of R2C3 and R3C2 can't be 9 since R1C1 is a 9.
