Elevator Action (First Hidden Skyscraper Sudoku)
(Published on 19. July 2024, 16:16 by glum_hippo)
Standard Sudoku rules are in effect: fill each row, column, and 3x3 box with the digits 1-9 once each.
Each digit in the grid represents a skyscraper of that height. Clues outside the grid give the height of the first skyscraper that cannot be seen when looking into the grid from the position of the clue. A skyscraper is visible only when it is taller than all buildings in front of it.
The digit 'x' is the same in both instances where it appears, and must be deduced by the solver.

Solution code: The nine digits of column 8, read from top to bottom

This is a great puzzle that somehow confused me and prevented me from using any known technique. It's a clever setup, thank you very much!

Thanks for leaving a message and for your interest. The logic is quite elusive at first.

Love it! Had to try some time to get the focus on the box for breaking in. It is indeed a very strong combination of clues to start with - just hard to see.
