Normal sudoku rules apply. Adjacent digits on a green whispers line must have a difference of five or greater. Digits on a thermometer must strictly increase from the bulb end. Numbers outside the grid indicate the sum of the digits on their indicated diagonal. Digits on these diagonals may repeat when otherwise allowed. I think this puzzle is 1.5 stars out of 5 for difficulty for many solvers. As always, comments welcome!
