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.
Counting circles: A digit in a black circle appears in black circles exactly that many times.
Killer: Digits in a cage sum to the small clue in the cage's top-left corner. Digits may not repeat within a cage.
Arrows: Digits along an arrow sum to the digit in that arrow's gray circle. Digits may repeat on an arrow if permitted by the other rules. Gray arrow circles are not counting circles.
