Normal Sudoku rules apply. PARROTY LINES: A 'word' is a non-repeating sequence of digits, like '365', '24', or '7' (but not '747'). Each white Parroty Line consists of one or more copies of the same word. The digit on a parrot indicates the length of the word the parrot is saying. (Example: a parrot with a 3 could be saying “486 486”). Digits in a cage sum to the attached tag.
