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.
Arrow Sudoku rules apply. Digits along the arrows in the grid must sum to the digit in their circle.
The grey squares are even numbers. The grey circles are odd numbers.
The puzzle is also available online.
