Normal sudoku rules apply. One digit from 1-9 (to be determined) is 'inactive' and always gets ignored by any line it appears on. REGION SUM: The 3x3 box borders divide blue lines into segments which each have the same sum (not counting any inactive digits.) The region sum may be different for different blue lines. RENBAN: All active digits on a pink line must form a non-repeating consecutive set. NABNER: Any two active digits anywhere on a yellow line may not be consecutive or the same.
