Is this your lucky day, and will you just roll through this puzzle like any other? Or... will you be desperate to escape the torture of the (little) killers?

The usual killer sudoku rules apply:

• Normal sudoku rules apply, i.e. each of the digits from 1 to 9 needs to appear exactly once in each row, column, and 3-by-3 box.
• An area in the grid surrounded by a dashed line is called a 'killer cage'. The number in the upper left corner of a cage is the sum of the digits within that cage. Digits cannot repeat within a cage.
• Digits along diagonals indicated by arrows must sum to the given number at that arrow. Digits may repeat along a diagonal.
