How to play Skyline

Build a city

Choose a height, then tap a square. Use 1 to 5 once in each row and column.

Read the view

A taller building hides shorter buildings behind it.

Count what you see

Each edge number tells you how many buildings are visible from that side.

Three ways to find your next move

1. An edge clue of 1 means the tallest building stands at the front. An edge clue of 5 means every height rises in order.
2. Use the row and column rules together. A missing height can be forced even when its edge clues seem uncertain.
3. Imagine the view from both ends. A tall building can hide several smaller ones, but it cannot hide a taller building behind it.
