Normal Sudoku rules apply
Boxer: exactly one cell in each row, column, and box is a "boxer", and boxer cells contain a complete set of the digits 1-9. The value of a boxer cell is equal to its box number, the value of any other cell is equal to its digit
None of the boxer cells have a value equal to their digit
German whisper: values of adjacent cells on a green German whisper line differ by at least 5
