The Bitwise OR operator idea was inspired by the occasional 8x8 Bitwise OR daily Calcudoku ,feeling it is a fun idea, so I decided to try to integrate it with Killer Sudoku.

Rules:
1.Normal Sudoku Rules apply.
2.Digits in a cage may not repeat and the number at the top left corner of the killer cage is either the sum or the results of Bitwise OR operator result of the digits in that cage.
Appendix: Bitwise OR (|) operator (Binary System):
Bitwise OR | Rules： 0 + 0 = 0 0 + 1 = 1 + 0 = 1 + 1 = 1.
Example: 5 | 9 =
|| 0 1 0 1
+ 1 0 0 1
------------
= 1 1 0 1 = 13

Here`s the puzzle.
and here`s the digits written in Binary system:
