Normal Sudoku rules apply. Each row, column and 3x3 box contains each number from 1 to 9 exactly once.
The black dots represent a 1:2 ratio, the white dots represent a difference of 1 between two neighbouring cells. NOT all possible black and white dots are indicated; a.k.a. no negative constraint.
Digits along the thermometers must increase from the bulb end.
The puzzle is also available online.
Solution code: Row 4 and Row 8
