The brief
Normal Sudoku rules apply.
The green line is a German Whisper; its digits must have a difference of at least 5.
The red line is a parity line; it must contain one even digit and one odd digit.
The purple line is a renban; it must contain three consecutive digits (but they can be arranged in any order).
The yellow line is entropic; it must contain one low digit (1, 2 or 3), one medium digit (4, 5 or 6) and one high digit (7, 8 or 9), in any order.
Adjacent digits on ANY line must sum to 10 or 11.
