Apply normal sudoku rules. Digits separated by a knights move in chess cannot be the same. Digits along arrows sum to the number in its connected circle. Digits along thermometers increase from the bulb.
The puzzle is unique without the given 6, but adds unnecessary difficulty to the solve. Enjoy!
Solution code: Row 1, Column 8

Fun start, both aesthetically and for solving, but the second half is sadly just pretty unpleasant trying to propagate the center to the outer parts. This happens quite often in Anti-Knight puzzles that don't have at least something for the outer parts.
