This should get your mind thinking in some interesting new ways about numbers! The digits in a given outlined area must add up to the little number for that area. But the thing that makes it killer, are those little numbers in the left corners of each of the red outlined areas.

In addition to the regular sudoku rules, each of the outlined areas must add up to the total given for that area. You might find killer sudoku puzzles easier or harder than regular sudokus.
