Stack Tower

Stack Tower

One tap. How high can you go?

Blocks slide across the screen. Tap to drop one, and only the part that lands on the tower stays. Miss and the tower shrinks. Miss completely and it falls.

How to play

• Tap the screen, or press Space, Enter or the Down arrow, to drop the block.
• Line it up with the block below. Whatever overhangs falls away.
• Land it almost perfectly for a Perfect drop. It keeps its full width and scores 10 points. A normal drop scores 1.
• Chain 4 perfect drops in a row and the block grows back a little.

Watch out

• The blocks get faster as you climb.
• From floor 8, special blocks appear. A block with a solid outline is fast. A block with a dashed outline turns around once mid-slide.

Features

• Simple one-tap controls that work on phone and desktop
• A sky that goes from sunset to day to starry night as you climb
• A rising chime and sparks on every perfect streak
• Milestone celebrations, a streak meter and rank titles from Rookie Builder up to Legend
