Skyline: Tower Logic

Build a tower on every lot of a city block at dusk. Every row and every column has one tower of each height, and the numbers on the edges say how many towers you can see from there – a taller tower hides every shorter one behind it. 280 city blocks, each with exactly one solution you can reach by logic alone – never a guess. When the block is complete, its windows light up one building at a time.

Frequently asked questions

How do I play?

Tap a lot, then a height to build that tower; tap the same height again to take it down. Switch on Notes (the pencil) to jot the heights a lot may still take, and use the eraser to clear a lot. With Auto-clear on (Options), a tower removes its height from the notes in its row and column.

How do I count the towers I can see?

Look along the row or column from the clue. A tower is seen when it is taller than every tower in front of it. For example, the row 2, 1, 4, 3 shows 2 towers from the left – the 2 and the 4.

Some edges have no number.

On harder blocks some clues are missing on purpose: those lines can show any number of towers. On Expert a few towers may already stand.

I bought a pack but the levels are still locked.

Open any locked level to get to the Purchases page and tap Restore Purchases. Make sure you are signed in to the store with the same Google or Apple account you used to buy it.

I got a new phone. Is my progress saved?

Purchases are tied to your store account and can be restored on any device. Your progress and best times are stored only on the phone you played on and are not synced.

Do I ever need to guess?

No. Every block has exactly one solution and can be solved by logic. If you are stuck, the Hint button first shows where to look, then explains why, and only then makes the move.

What do the free and paid levels include?

All 40 Easy levels (including a five-level tutorial), a free daily puzzle and the first 10 levels of Medium, Hard and Expert are free. The rest come in one-time packs of 35 levels, or all at once. There are no ads, no subscriptions and no account.

What data does the app collect?

Only anonymous gameplay statistics and crash reports, and you can switch them off in Options – see the privacy policy.
