Rules: Normal Sudoku rules apply. Among the digits 1–9, three are red, three are green, and three are blue (each digit has exactly one color, to be determined by the solver). Along each marked line, either all digits must be of the same color or all of mutually different colors. Lines behave differently depending on the colors of the digits they contain:

• if all digits are red, the line acts as a same-parity line (i.e. all digits are even or all are odd);
• if all are green, it acts as a German whisper (i.e. adjacent digits differ by at least 5);
• if all are blue, it acts as a region-sum line (i.e. box borders divide it into segments with the same sum); and
• if no color repeats, it acts as a renban (i.e. it contains a set of non-repeating consecutive digits in any order).
