How to Play Skyscrapers

Rules

  • Fill every cell with a building height from 1 to 4.
  • Each row and column must contain each height exactly once.
  • Border clues tell you how many buildings are visible from that direction.
  • Taller buildings block the view of shorter ones behind them.

Key Deductions

  • A clue of 1 means the tallest building (4) is right at the edge.
  • A clue of 4 means the buildings go in ascending order (1, 2, 3…4).
  • No clue shown? That constraint is hidden — deduce it from other clues.

Controls

  • Click a cell, then tap a number to place it.
  • Use arrow keys to navigate between cells.
  • Press N for notes/pencil mode, B for buildings view.
  • Press H for a hint.

About easy Skyscrapers (4×4)

Easy Skyscrapers uses a 4×4 grid with 12 to 16 border clues shown and 1 to 3 given cells. With only 16 cells, direct clue deductions handle most of the work. A border clue of 1 means the tallest building (height 4) is in the first position. A clue of 4 means the row or column is in ascending order: 1, 2, 3, 4. These two deductions alone can fill a quarter of the grid before you need anything else.

Given cells reduce the search space further. After placing heights forced by clues, use Latin-square elimination: if a 3 already appears in a row, no other cell in that row can be 3. On a 4×4 board this cascading elimination usually finishes the puzzle within minutes. If a row or column is nearly full, count the missing heights and slot them in.

Easy puzzles are great for learning the visibility mechanic. Try the buildings mode toggle (B key) to see proportional height bars, which makes it obvious which ones are “blocked” by a taller neighbor. Once you are solving these in under 2 minutes, step up to medium (5×5).
