Build Top City

Build the tallest tower — one jump at a time
You’re a builder climbing an endless tower! Tap to jump onto moving blocks coming from the left or right. Each successful jump locks the block in place and grows your skyscraper.

Mistime your jump and you’ll fall — or get crushed by a block. The tower starts shaking if blocks are misaligned, increasing difficulty.

Progress through three visual zones: city base (<25 blocks), skyscrapers (25–50), and clouds above 50. Can you reach the sky without a single misstep?
