How to play Skyscrapers

Rules

1. Use every number from 1 to the grid size once in each row and column.
2. An edge clue counts buildings visible from that side; taller buildings hide shorter ones behind them.
3. A ? gives no visibility constraint.

How to answer

1. Select a cell, then choose its height. Use Notes to add or remove possible heights.
2. Choose Check grid when the grid is filled.
3. Your entries and notes are saved. Undo reverses edits and clearing.

Solving tips

• A clue of 1 forces the tallest building at that edge. A clue equal to the grid size forces increasing heights away from it.
