Astro Stack

Tap at the perfect moment, stack every block, and build a tower that reaches beyond the sky!

Astro Stack is a satisfying one-touch stacking game that tests your timing, focus, and precision. Release each moving block at the right moment, keep it aligned with the tower below, and climb as high as you can.

The controls are simple, but every decision matters. An off-center placement can make your tower lean and sway, turning each new floor into a greater challenge. As your tower grows, the blocks move faster and the structure becomes harder to control. Miss the tower completely, and your run is over.

Think you have perfect timing? Land blocks accurately to earn perfect placements, build longer combos, and collect bonus points. Stay calm under pressure, beat your best height, and return for another fast and exciting attempt.

YOUR JOURNEY GOES BEYOND THE SKY

Begin your climb above a colorful 3D city filled with roads, traffic, trees, and atmospheric scenery. Continue upward through bright clouds and a dramatic lightning storm before finally entering outer space.

Your adventure does not stop there. Travel past Saturn, Mars, and Pluto as the view changes around your ever-growing tower. Once you reach space, a mysterious alien begins climbing from below. Keep building before it reaches the top!
