Skyliner: Tower Stack City

A crane swings a floor on a cable. Tap once, and let go at exactly the right moment.

Land it dead centre and residents parachute in under umbrellas, your streak climbs, and the tower stays plumb. Land it badly and it leans - and every floor after that gets harder, because a tower that is already crooked sways further, and the block you are aiming at will not sit still.

Stack too far over one edge and it does what it should: it comes down.

BUILD YOUR CITY Every finished tower gets placed on a city grid, and each new contract comes with a rule about what it has to be built next to. Blue residential, red commercial, green office, gold luxury - and, once you have earned the room, a Mega Tower that has to be hemmed in by all four. Fill all twenty plots and a new district opens, with its own sky, its own ground and its own skyline.

FOUR WAYS TO PLAY • Build City - the campaign. Contracts, neighbours, districts. • Endless - one tower, as high as you can take it. • Time Attack - sixty seconds. A perfect drop buys two more; a miss costs five. • Versus - two players on one phone. The screen splits, and the top half turns around so you can sit opposite each other.

EARNED, NOT BOUGHT Four perfect drops in a row earn a balcony floor that houses twice as many people. Top out with most of your floors dead centre and the building gets a trophy roof. Coins go to the depot for a spare crane, a steadier cable, or a wind anchor.

THE CLIMB Start at noon on a building site and keep going. The sky moves through afternoon, sunset and night, the city lights come on beneath you, and the wind starts to matter somewhere around the fortieth floor.

Every sprite is drawn in code and every sound is synthesised - nothing here is a stock asset. No ads. No timers. No pop-ups asking you to wait.
