Skyscrapers Sudoku
(Published on 11. December 2021, 11:33 by Qodec)
- Normal sudoku rules apply: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- 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.

Solution code: Row 5 and column 5. I.e. the 9 digits in row 5 from left to right, followed by the 9 digits in column 5 from top to bottom, for example: 123456789123456789

Nice and tricky for me - I don't find skyscraper particularly intuitive.

I loved this puzzle. The fact that this has a unique solution with these clues looks absurd when you start, but after breaking in and staring for a while, it was extremely elegant.

What an elegant construction. I really like the break-in. Definitely 4 stars for me. I got stuck in the middle, thanks Qodec for the quick hint.

A tad below 3½ stars difficulty for me - I think it's 4 stars for anyone who isn't well versed in the common skyscraper techniques.

Wonderfully clever puzzle as always, the interactions between the clues are very beautiful! I did break it once but whatever, doubled the fun :D
