This puzzle is dedicated to my friend Michael. He helps me a lot testing my puzzles. I tried to forge a puzzle with the constraint he dislikes most: the anti-knight constraint. My goal was, to make the puzzle that much fun to solve that even he starts to like anti-knight puzzles. What do you think? Leave a comment: do you like anti-knight puzzles? Do you like this specific puzzle?

Rules:

Normal sudoku rules apply.
Digits on Thermos are strictly increasing from bulb to tip.
Adjacent digits along a green line must differ by at least 5.
Anti-knight: Cells that are a chess knight’s move apart cannot contain the same digit.
