Normal sudoku rules apply. Adjacent digits along a green whisper line must differ by at least 5. Digits along a thermometer must increase from bulb to tip. The low digits (123), middle digits (456), and high digits (789) are defined as three different groups. In the finished grid, each 2x2 box must contain at least one of each group. [The blue line is purely decorative]
