How to play Skyscrapers

Rules

1. Use the numbers 1 through the grid size in every row, with no repeats.
2. Use the numbers 1 through the grid size in every column, with no repeats.
3. Edge clues show how many buildings are visible looking across that row or column from that side.
4. A ? clue means that side is unknown and gives no visibility count.
5. Taller buildings hide shorter buildings behind them.

How to answer

1. Tap a cell, then tap a number to set that building height.
2. Start by making each row and column contain every height once.
3. Use the edge clues to check visibility: from a clue side, count a building only when it is taller than all buildings before it.

Solving tips

• A clue of 1 puts the tallest building nearest that edge.
• A maximum clue means heights must rise in order from that edge.
• If a row already has a number, that number cannot appear again in the row or column.
