Stackonaut - Stack to Space

Tap to stack. Build your space elevator from a city street to the stars. Easy to play, tricky to master, how high will you go today?

Build the tallest tower the world has ever seen, one gentle tap at a time.

STACKONAUT is the cozy little stacking game with a big dream: a space elevator that starts on a city street and ends among the stars. Drop each new piece from the delivery drone, line it up just right, and watch your tower climb past clouds, storms and auroras, all the way to the edge of space.

EASY TO PLAY, HARD TO PUT DOWN One finger. One tap. That's the whole game. Kids get it in seconds, grandparents get hooked in minutes. But landing every single piece perfectly? That takes a Stackonaut.

A WORLD THAT FLOATS BY Wave at hot-air balloons and gliders. Spot a parachutist drifting past your tower. Watch tiny astronauts jetpack up and climb in through the round windows. And keep your eyes open for rare visitors, a flying saucer, a shooting star, even a red sports car cruising through space.

THE SKY KEEPS CHANGING City mornings, howling jet streams, the calm quiet of the stratosphere, glowing auroras, and finally the deep black of space, with the whole Earth shining below your tower. Every 100 floors earns you a badge to keep.

PERFECT DROPS ARE MAGNETIC Land a piece dead-center and it locks on tight, meteor storms and hurricanes can't shake it loose. Sloppy pieces wobble and slide… and that's when things get exciting.

REACH FLOOR 999 Finish the elevator and dock the great wheel station at the edge of space, then start again with your golden carrier. Only true Stackonauts make it.
