- Normal sudoku rules apply: fill the grid with the numbers from 1 to 9 so that in each row, column, and 3x3 block, each digit occurs exactly once.

- The digits in adjacent cells along a green german whisper line must differ by at least 5. Digits can repeat on green lines if allowed by other rules.

- The dashed lines define a killer cage. A number in the top left corner of a cage indicates the sum of all the digits in this cage. Digits may not repeat within a cage.

The puzzle is also available online on SudokuPad. Have fun solving!
