Catch the Impostor!
By Jeff Wajes
The number zero has disguised itself as one of the usual Sudoku digits (1-9) and taken its place on the grid! This impostor's disguise may fool the human eye, but it can't fool the Killer Sudoku cages.
Normal Sudoku rules apply.
Digits cannot repeat inside a cage.
The small clue in the top left of a cage indicates the sum of the contained digits EXCEPT for the impostor digit, which is ignored. You must deduce which digit is the impostor.
For example, if the digit 1 were the impostor, a "5" cage could contain the digits 1, 2, and 3.
Enjoy!
Solution code: Row 5, replacing the impostor digit with 0 (zero).
