Rules:

Normal Sudoku rules apply. Normal Variant rules apply.

Place the digits 1-9 in each row, column and 3x3 box. Consecutive digits on a lime green German Whisper line must differ by 5 or more. Digits on a thermometer must increase in value from the bulb end. Digits separated by a black dot have a 1:2 ratio. Digits separated by a white dot have a difference of 1. The grey circle in R9C9 is an odd digit. Digits on the Phistomefel ring... you know the rest!
