This is my first stab at arrows with (hopefully) some interesting logic. Enjoy!
Rules:
Normal Sudoku rules apply. (Place the digits 1-9 in every row, column, and box)
Arrow: Digits on an arrow sum to the digit in that arrow's circle. Digits can repeat on arrows if allowed by other rules.
Thermo: Digits on a thermometer must increase from the bulb end.
Solution code: Row 2 and column 7 (as a string of 18 digits)
