Normal and Killer Sudoku rules apply. Each row, column, and 3x3 box contains each number from 1 to 9 exactly once. The sum of all numbers in a cage (marked with dashed lines) must match the small number printed in its corner. No number appears more than once in a cage.
The puzzle is also available online.
