Test your precision and timing as you strive to build the tallest tower possible. Your task is to stack blocks on top of each other, but be careful not to make the tower too unstable, or it will collapse!

In Stack Builder, you'll start with a small platform and a single block. Tap the screen to drop the block onto the platform, aiming for the perfect alignment. As the tower grows taller, the blocks become smaller and more difficult to stack accurately. You'll need steady hands and quick reflexes to succeed!

Challenge yourself to reach new heights and unlock additional block types with unique properties. Some blocks might be heavier, lighter, or have irregular shapes, adding an extra layer of complexity to the game. Strategize your moves and plan ahead to create a stable tower that defies gravity.

Compete against friends or players worldwide in the multiplayer mode, where you can compare your tower heights and see who can construct the most impressive structure. Can you become the ultimate Stack Builder champion?
