Skyscrapers Game Guide

📖 About

Skyscrapers is a 3D logic puzzle where you place buildings of heights 1-N on an N×N grid. Clues outside the grid show how many buildings are visible from each direction. Taller buildings hide shorter ones behind them. Play Skyscrapers free online — Sudoku-style logic with a 3D twist!

🎯 Objectives

Fill the grid with buildings 1-N so that each row and column contains each height exactly once, and visibility clues are satisfied.

🎮 How to Play

Place buildings 1-N in each row and column (like Sudoku). Clues show how many buildings are visible when looking from that direction. Taller buildings hide shorter ones behind them.

⌨️ Controls

Click a cell and enter 1-N (the building height). Each row and column must contain each number 1-N exactly once.

❓ Frequently Asked Questions

How does visibility work?
When looking from a direction, you count visible buildings. A taller building blocks view of shorter ones behind it. So if you see 5-3-7-2 from left to right, you'd see buildings 5 and 7 (3 is hidden by 5, 2 is hidden by 7).
What's the common starting strategy?
Look for clues of 1 or N first. A clue of 1 means the tallest building is right at the edge. A clue of N means buildings must be in ascending order 1, 2, 3... N.
How is this like Sudoku?
Like Sudoku, each row and column must contain each number 1-N exactly once. The visibility clues add a unique 3D perspective that makes this puzzle fresh and challenging.
What's the best grid size for beginners?
Start with 4×4 or 5×5 grids. They have fewer clues and are easier to solve while learning the visibility mechanics.
Can I solve Skyscrapers without guessing?
Yes! Every well-designed Skyscrapers puzzle can be solved through pure logic. Start with the most restrictive clues (1 and N), then use Sudoku-style elimination for the remaining cells.
Can I play Skyscrapers free online?
