Stack It! - Build to Space

How high can you stack?

Tap to drop the sliding block onto your tower. Land it perfectly and you keep your full width. Miss the edge and your block gets trimmed, one bad drop at a time, your tower gets thinner and the pressure builds.

Stack It! is a free block stacking game with a simple rule and an impossible ceiling. One-tap controls, endless replayability, and a "just one more try" loop that's impossible to quit.

As your tower grows, the world changes around you. Stack blocks through rolling green hills, past drifting clouds, into a deep blue sky, and if you stack high enough, through the upper atmosphere and out into space. Birds flock past in the low sky. Planes cross the horizon. Satellites blink in the dark above. The higher you go, the more there is to see.

Simple to learn. Hard to master. Impossible to put down!
