Normal Sudoku rules apply. Place the digits 1 - 9 once in every row, column and box.
Thermometers: Digits on a thermometer must increase from the bulb end.
Region Sum Lines: Blue lines are Region Sum Lines. Box borders divide them into segments with the same sum. Different lines may have different sums.
For clarity: Every thermometer (including the bulb) is also a region sum line.
