Logic Masters Deutschland e.V.

This is the first puzzle in my '3 Series'.

I wanted to explore, if skyscrapers of size 3 are enough to shape a puzzle around. The resulting puzzle is fairly approachable and the logic just worked out. I hope you enjoy solving it as much as I did making it.

Rules:

Normal sudoku rules apply.

Skyscrapers: clues outside the grid indicate how many numbers can be "seen" when looking into the grid along the row or column. A number is visible only when it is larger than all numbers that appear before it along the line of sight.

Ratio dots: All cells separated by black dots must contain digits in a 1:3 ratio.
