A puzzle to practice your anti-knight scanning.
Normal sudoku rules apply.
Thermometer: From the bulb to the tip of a thermometer line digits must strictly increase. There are also four 4-cells thermometers with a bulb at one of the end, which must be deduced by the solver.
Anti-Knight: Cells separated by a knight's move (in chess) cannot contain the same digit.
Puzzle:
Fun fact: there exist many two 8-cells thermometers + anti-knight puzzles. However I decided to add 4 more ambiguous thermometers to make it more nicer to view.
Solution code: Box 8 please.
