About Tower Building
Tower Building is a timing game built around a swinging block and a growing stack of floors. Click or tap to release the next floor when it is lined up with the tower. A successful placement adds a floor; a perfect placement earns more points. The default game gives you three hearts, and a falling block costs one. This page hosts iamkun’s open-source Tower Building project, with the rules and assets included in that version.
Getting started
- Press the start control inside the game.
- Watch the swinging floor and click or tap when it lines up with your tower.
- Stack floors, aim for perfect landings, and protect your three hearts.
Tips for a better run
- Watch one complete swing before releasing if you need to learn the rhythm.
- Use the center of the previous floor as your alignment reference.
- A safe landing keeps the run alive. Do not chase perfect points when your timing is uncertain.
Common questions
How is the score calculated?
Under this version’s default rules, a successful floor earns 25 points, a perfect floor earns 50, and consecutive perfect placements add a further 25-point bonus per step.
How many mistakes can I make?
You start with three hearts. A falling block costs one heart; the run ends when none remain.
Will it work on my school network?
Access depends on your network’s rules. “Unblocked” is a common search term for browser games, not a guarantee that a school or workplace will allow this page.
