Standard Sudoku rules apply. All 3 grey circles under the questionmark lines contain the same digit. But I need your help with the 3 grey questionmark lines: which one follows which rule?

- one German Whispers line: the digits have a difference of at least 5 to their neighbor(s)

- one Thermometer: digits increase, starting from the bulb. Oops, no bulb, you'll have to figure out at which end of the line the bulb is

- one Renban line: all digits along that line form a consecutive sequence in any order

Kropki: white dots link cells which have a difference of 1. Black dots link cells which have a ratio of 1:2. Not all possible dots are given.
