Normal sudoku rules apply. Digits in cages must sum to the given total. Digits on arrows must sum to the digit in its attached circle. Digits on thermometers must increase from the bulb end.
Extra Challenge
If you are brave or foolhardy: The puzzle has a unique solution even without the 7 cage, the 10 cage, and the 13 cage in box 6. Can you solve it without relying on these three cage clues?
