The brief
Normal sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box. Cells separated by a black dot has one digit double the other (1:2 ratio). Cells separated by a white dot are consecutive. Adjacent digits along a green line must differ by at least 5. Digits on a slow thermometer must never decrease from the bulb end. Clues outside the grid sum the digits along the indicated row/column that appear between the 1 and 9. No negative constraints.
