Basic Rules / How to Play

  • Grid Size: The puzzle consists of a 9x9 grid, divided into nine 3x3 sub-grids, often referred to as "boxes" or "regions."
  • Unique Numbers: Each row, column, and sub-grid must contain the digits 1 through 9 exactly once.
  • Numbers in the grid represent the "heights" of skyscrapers.
  • Clues are placed around the edges of the grid, outside the rows and columns.
  • Each clue indicates how many skyscrapers are visible from that direction, considering the heights of the skyscrapers.
  • Taller skyscrapers block the view of shorter ones behind them.
  • Example: If the clue is "4" and the row starts with skyscrapers of height 1, 3, 5, and 6: The visible skyscrapers are 1, 3, 5, and 6 because no taller skyscraper blocks the view.
