Inner Skyscrapers
(Published on 30. September 2022, 23:08 by tesseralis)
Normal sudoku rules apply.
Digits in a grey square are even.
Numbers in the grid represent the heights of skyscrapers, where larger digits block the view of smaller digits behind them. Arrows outside the grid indicate that X skyscrapers are visible in that direction in that row or column, where X is the digit in the cell immediately adjacent to the arrow.
Solution code: Row 5 followed by column 5

very clean and fun construction! I also don't know whether this has been used, but I used a similar constraint once (only with the last cell instead of the first one)

thank you filuta :) ~tess

Great puzzle, very nice and minimal using the X-skyscraper constraint. Perhaps not as difficult as 5 stars?
--
Haha, I was about to change it to 4 stars but it got enough for an official rating.
Are X-skyscrapers a pre-existing constraint? I couldn't find any in the CTC server. ~tess
