Modest Urban Planning (Skyscraper, Halver)
(Published on 25. July 2025, 12:59 by Mad-Tyas)
Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.
Halver: There are nine Halver cells in the grid, exactly one in each row, column and marked 3x3 box and filled with a complete set of the digits 1-9. The value of a Halver cell is half the digit in that cell.
Skyscraper: Each cell represents a skyscraper whose height is given by the value of the cell. A skyscraper blocks the view on all skyscrapers of the same or lower height standing behind it. Clues outside the grid give the number of skyscrapers seen from that direction in the corresponding row or column.
Have fun solving!

That was a beautiful, but quite hard break in with the halvers messing with the usual skyscraper assumptions. Thanks for sharing.
