Normal sudoku rules apply.
Quadruples: Digits in circles must appear in the 2x2 area around the circle.
Extended Renbans: Digits along a pink line form a consecutive group in any order. Digits do not repeat on the line EXCEPT for the ends, which are the SAME digit.
For example, possible fills for a line of length 5 might be 64756, 25342, 34123, etc.
