The brief
Normal sudoku rules apply. Place the digits once each in every row, column and 3x3 box. Digits on a thermometer must rise from the bulb end. Digits on a green line must differ by at least 5. Clues outside the grid sum the digits between the 1 and 9 in their respective row/column. Cells separated by a black dot has one digit double the other. Cells separated by a white dot are consecutive. Cells separated by a V sum to 5. Cells separated by an X sum to 10. No negative constraints.
