This is an example of a finished Thermo Sudoku grid.
The normal rules of Sudoku apply, i.e. each row, column and 3x3 region must contain the numbers 1-9.
Additionally, the grid contains a series of 'thermometers'. Numbers along the thermometer must be increasing
with the lowest number in the round 'bulb' of the thermometer.
