Normal sudoku rules apply.
Anti-knight rules apply: A digit must not appear a chess knight's move away from itself.
Killer rules apply: Digits must not repeat in cages. Where given, digits in cages sum to the number in the top left corner.
The twelve blank cages have the following values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. It is up to the solver to discover which cage goes with which value.
Solution code: Column 1
