Skyscrapers
Place buildings so the visibility clues match from every direction. A Latin-square logic puzzle.
The rules
How to play
- 01
The grid
Fill the N×N grid with numbers 1 to N — a 4×4 puzzle uses the heights 1 through 4. Each number is a building of that height.
- 02
Rows
Every row must contain each number from 1 to N exactly once. No height repeats along a row.
- 03
Columns
The same rule holds vertically: each column holds every height exactly once, top to bottom.
- 04
Edge clues
The numbers around the border tell you how many skyscrapers are visible looking in from that direction.
- 05
Visibility
A taller skyscraper hides every shorter one behind it. The clues count only the buildings you could actually see.

Six habits of sharp solvers
Edge clues of N
A clue equal to the grid size forces a strict climb — 1, 2, 3, 4. Only one arrangement makes every building visible.
Edge clues of 1
A clue of 1 means the tallest building stands right against that edge, blocking the whole row or column behind it.
Read both ends
Look at the clues on opposite sides of a row or column together. Paired clues sharply narrow the possible orders.
Start with extremes
Clues of 1 and N are the most restrictive on the board. Find where the tallest building must sit first.
Latin-square logic
Just like Sudoku, no height repeats in a row or column. Use elimination to whittle each cell down to one option.
Work both directions
Once a height is fixed, re-check how it changes visibility from both ends of its row and its column.
