Normal sudoku rules apply. Place the digits 1-9 in each row/column/box without repeating.
Little Killer - Digits along marked diagonals sum to the given clue. (R9C1 references the value in row 9 column 1)
Knight Regions - Each cage marks the center cell of a region that includes every cell seen by knights move (including the caged cell). Digits may not repeat within a knight region. A number in a knight region cage represents the sum of the digits within that region, if given.

Wow, monster was not exaggerated. Really good fun though. Loved the way the symmetry and knight regions played together.

This was hard enough I had to step away and return to finish the solve, but my goodness was it worth it. This puzzle is exceptional on many levels, but very tough. The symmetry, the break in, the arithmetic to keep straight, scanning across the knight regions...wow. just incredible, so fresh. One of my favorites for the year

One of the hardest puzzles I have ever solved. Really enjoyed the process. The simplicity of the design hides the horrors and fun that is hidden in this.
