Skyline: Tower Logic

A city block at dusk, empty lots and numbers on every street corner. Build a tower on every lot, and when the block is right, its windows light up one building at a time.

Skyline is a calm, clever skyscraper logic puzzle. There is no luck and no guessing: every block has exactly one solution, and you can reach it by reasoning alone.

HOW YOU PLAY
• Every row and every column has exactly one tower of each height.
• A number on the edge says how many towers you can see from there: a taller tower hides every shorter one behind it.
• Tap a lot, then a height to build. Tap the same height again to take the tower down.
• Notes (the pencil) jot the heights a lot may still take; Auto-clear keeps them tidy.
• Undo and redo any move.

HINTS THAT TEACH
Stuck? The hint first outlines where to look, then explains the reasoning – and only makes the move if you ask. The first time a new idea comes up, it is explained in general, so you learn the trick instead of just getting the answer.
