Sudoku: Fill every row, column and 3x3 box with the digits 1-9.
Killer: In cages marked with a black dashed line digits must not repeat and have to add up to the total given in the top left corner of the cage.
Arrow: Digits on an arrow have to sum to the digit in the corresponding circle and may repeat if allowed by other rules.

Have fun solving!
