Logic Masters Deutschland e.V.

A guy on the diagram just sat to solve yet another puzzle and make a video of it but much to his dismay and disappointment the rules are worded as follows:

The pink mouth contains digits from x to x+n once each where x is any valid sudoku digit and n is the length of the mouth decremented by 1.

Each of the blue-lined tears separately sums up to the same number in each box it visits.

The right (left from our perspective), closed eye of the guy has identical logic to his mouth. On the other hand, the left one (right from our perspective), opened eye, separates cells with consecutive digits.

There is a transparent line in each row and each column. It has a length of nine and it works as if it was a pink line, like mouth or closed eye, but it is transparent.

This already looks too disappointing to sing, and there is more.

The grid contains only the following digits (in alphabetical order): eight, five, four, nine, one, seven, six, three, two. Each cell contains exactly one of these digits which should be placed in the center of the cell.

The bolded lines are killer cages. The sum of each killer cage is 45 although it is not shown on the grid. The digits in a killer cage must not repeat.

Each pair of digits connected by one of the black nostrils must sum up to the exactly tripled value of the lower of the digits in pair.

The green glasses whisper in some unknown language but one can tell that the digits placed along this line hate each other so much that four is too little as a distance between the neighbours' values. Five seems to be ok.

The sequence along the gray eyebrow line is one and the same, regardless whether you walk along the eyebrow from right to bottom or from left to top. But don't walk on the guy's eyebrow anyway, it hurts and he's already sad.
