Rules
Normal sudoku rules apply.Parity Thermometers: Turquoise (orange) thermometers restrict only even (odd) digits. That is, on a turquoise thermometer, the even digits strictly increase from the bulb end, and likewise for odd digits on an orange thermometer. Digits of the unrestricted parity can go anywhere and in any order on a thermometer.
Thermometers are strictly dominated by digits of the restricted parity. E.g. a 6 cell orange thermometer must have at least 4 odd digits.

How it it possible on r1c9 and r9c1 to be max and min of a sequence at one tome since it is bulb and tip at the same time. Unclear to me. It seems not to implicate that this cell is odd does it?
— PFF:
Unless I misunderstand, you already cracked it - how could those cells contain odd digits and leave a valid thermo? Remember, even digits CAN appear anywhere on an orange thermo as long as the majority of digits on the thermo are odd! Also, it is only the odd digits that are required to strictly increase along the thermo
