Normal sudoku rules apply.
The grey line ("6") is a palindrome that reads the same in both directions.
Digits along the thermometer ("1") must increase from the bulb end.
Digits in cages sum to 13; negative constraint applies -- no unmarked dominoes sum to 13.
Digits separated by a white dot differ by 1 (not all dots are shown).
