Up in The Sky
(Published on 14. February 2026, 18:23 by ICHTUES)
Rules:
- Normal Sudoku rules apply.
- The positive diagonal must contain all of the digits 1 to 9.
- The digits on an arrow add up to the digit in the corresponding circle.
- Each digit within the 9x9 region represents a skyscraper of that height. The clues outside the 9x9 grid tell the number of skyscrapers visible in that row/column from that side, with higher skyscrapers blocking the view of lower skyscrapers.
