==== RULES ====

Normal sudoku rules apply : Fill the grid with digits 1 to 9 appearing each exactly once in every row, column and 3x3 box.

Even marks : Grey squares contain even values.

Flat-Sharp marks : for all the below rules, a digit n is seen as :
- (n + 0.5) if it is in a cell marked with #
- (n - 0.5) if it is in a cell marked with b
- n in all other (unmarked) cells.

Non-strict between lines : cells on grey lines must have a value between or equal to the values of the grey circles at the ends of the line.

Thermometers : cell values strictly increase on grey thermometers, from the bulb to the tip.

German Whispers : on the blue-green line (row 5), a cell value must have a difference of at least 5 with its neighbors from the line.

==== EXAMPLES====

- A 3 in a cell on a thermometer and marked with # is counted as 3.5 (3 + 0.5) for the thermometer. The next cell on thermo must be seen as more than 3.5.

- A 7 in a cell on a whisper line and marked with b is counted as 6.5 (7 - 0.5) in the whisper line. Its neighbors on the line must be 2.5 or lower.

- If a between line has a 5 marked b and a 7 marked # in its circles, then all cells on the between line must be between 4.5 and 7.5, both values included. The line could contain a 4 marked #, or a 8 marked b.
