## Description

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.<br><br>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.<br><br>HOW YOU PLAY<br>• Every row and every column has exactly one tower of each height.<br>• A number on the edge says how many towers you can see from there: a taller tower hides every shorter one behind it.<br>• Tap a lot, then a height to build. Tap the same height again to take the tower down.<br>• Notes (the pencil) jot the heights a lot may still take; Auto-clear keeps them tidy.<br>• Undo and redo any move.<br><br>HINTS THAT TEACH<br>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.<br><br>280 CITY BLOCKS, FOUR DIFFICULTIES<br>• Easy – 4×4 blocks with every clue and a five-level tutorial that teaches every idea you need<br>• Medium – 5×5 blocks with fewer clues<br>• Hard – 6×6 blocks where counting the views matters<br>• Expert – 7×7 blocks, sparse clues and a few towers already standing<br><br>A NEW BLOCK EVERY DAY<br>A free daily puzzle, a streak to keep and the last seven days to catch up on.<br><br>All 40 Easy blocks, the daily puzzle and the first 10 blocks of Medium, Hard and Expert are free. More come in one-time packs, or unlock everything at once. No subscriptions, no ads, no account.<br><br>MADE FOR THINKERS<br>• Plays fully offline<br>• No account, no ads: only anonymous usage stats and crash reports, which you can turn off<br>• Your progress and best times stay on your device<br>• A violet-and-gold city at dusk with soft electric-piano notes<br><br>If you enjoy logic puzzles, Sudoku, KenKen or classic skyscraper puzzles, Skyline is your next favourite.
