• Normal Sudoku rules apply.
• Normal rules for renban (purple), Region Sum Lines (blue), and odd circles apply.
• Renban Lines: The purple lines in the grid are renban lines. Digits on a line form a set of non-repeating, consecutive digits in any order.
• Region Sum Lines: Box borders divide blue lines into segments. The sum of digits along each segment is the same. Different lines may have different sums.
• Gray Circles: Digits on gray circles are odd.
