Logic Masters Deutschland e.V.

Sorry for two posts in a short amount of time. This is a pretty tricky 6x6 version of the 9x9, but at least a few people on discord were able to solve it.

Rules:

-Normal 6x6 sudoku rules apply (place the digits 1-6 once in each row/column/box).
-Digits along a thermo must increase from the bulb end. Adjacent digits along a whisper line must have a difference of at least 3. Cells separated by a black dot must have a ratio of 1:2. Not all dots are given. However, the constraints have been deleted by some person named Monika. You only remember that they existed and what they (at least) partially looked like.
-A grey cage contains a thermo bulb and a green cage contains an end of a whisper line. The inequality (greater than X) in the top left corner of each cage indicates the minimum length of the thermo/whisper lines. Thermos and whisper lines do not travel diagonally, do not branch, and do not share cells.
-Cells with a circle are part of a group of N orthogonally adjacent cells connected by black dots, where N is the number in the circle. For example, if r2c5 was a 4, then at least one of the four surrounding cells must be a 2. Circled cells are part of different groups (i.e. two different circles can't satisfy both dot constraints by sharing a cell).
