I was surprised and delighted when putting together this puzzle. I hope you will be surprised and delighted too!

Ordinary Sudoku Rules Apply. Additionally:

1. Arrow rules apply: Digits along an arrow sum to the digit in the arrow's circle. Digits may repeat on arrows if allowed by other rules

2. Thermo Rules Apply: Digits along each thermometer must increase starting from the bulb end (and digits may not repeat along a thermometer).

3. Knights Move Rules Apply: Digits must not repeat in cells that are a chess knight's move apart.

That's it! Enjoy! :) You can play it here. Notice that when using the ctc link, one of the arrows is obscured by the thermometer.
