June Domino-month (2) - Skyscraper Domino
Paint some cells black and place all given domino pieces in the grid so that they don't overlap each other. Two orthogonal neighbouring cells from different domino pieces must be equal.Black cells may not touch the border orthogonally and they may not touch each other orthogonally.
The numbers on every domino represent two skyscrapers. The digits outside the grid are the number of skyscrapers that can be seen from that vintage point. A skyscraper is hidden by a higher skyscraper or a skyscraper of equal height. Black cells can be ignored; they have no height.
Solve online in Penpa+ (thx Nick Smirnov!)
Solution code: The digits and black cells in columns A and B, followed by rows C and D. 'S' for a black cell.

Here's the echo: Very, very wonderful!!!
I've needed several tries and everytime I've learned something new. It was so fascinating, that I couldn't stop trying to solve it.

Großartiges und schwieriges Rätsel. Habe sehr lange gebraucht. Hatte aber auch immer das Gefühl, dass ich ein entscheidendes Argument nicht sehe...?
