The brief
For an extra bit of fun, there is a hidden word puzzle in the grid and it is up to the solver to disambiguate what it says. Normal sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box. Cells separated by a white dot are consecutive. Adjacent digits along a green line must differ by at least 5. Digits on a thermometer must rise from the bulb end. Clues outside the grid give sum of the digits along the indicated diagonal, digits may repeat.
