Normal sudoku rules apply. Digits inside a cage must sum to a multiple of 3 without repeating a digit. Digits along a thermometer must increase from the bulb end. Cells with a grey square must contain an even digit.

F-puzzles link (F-puzzles does not recognize the "multiple of 3" rule so you won't get a red digit if you accidentally break this rule)

Have fun, any feedback is appreciated!
