Skyscraper Puzzles

Welcome to Puzzle Baron's Skyscraper puzzles! Skyscrapers (also known as Towers, Wolkenkratzer, or Building Heights) is a classic Japanese-style logic puzzle where you fill an N×N grid with buildings of varying heights, using only the edge clues and pure deduction — no guessing required. Every row and every column contains each height from 1 to N exactly once, and the numbers around the perimeter tell you how many buildings are visible from that side. We offer thousands of unique puzzles in four grid sizes (5×5, 6×6, 7×7, and 9×9) and three difficulty levels.

How to Play

Each puzzle presents an N×N grid surrounded by numbered clues on all four sides. Your goal is to place a building of height 1 to N in every cell, so that:

• — Every row contains each height from 1 to N exactly once.
• — Every column contains each height from 1 to N exactly once.
• — Each edge clue tells you how many buildings are visible when looking down that row or column from the outside. Taller buildings hide every shorter building behind them.
