Normal Sudoku rules apply. Orange lines are entropic lines; any set of three consecutive digits along a line must include one low (1-3), one medium (4-6), and one high (7-9) digit.

Each entropic line is ALSO either a German whispers line or a between line. On German whispers, adjacent digits must differ by at least 5; on between lines, the digits in the middle of the line must be between the digits on the ends. The solver must deduce which lines are whispers and which are between lines.

The inequality points to the smaller of the two adjacent digits.
