Gravity Stack

Turn the chamber. Change the fall. Build the perfect chain.

Gravity Stack is a colorful puzzle game where every rotation transforms the board. Rotate the entire chamber by 90 degrees, watch every energy cube fall under gravity, and connect three or more matching cubes to merge them into a stronger form.

Plan each turn carefully. A simple rotation can create one satisfying merge—or unleash a brilliant chain reaction. Keep making space and chase a new high score before the chamber fills.
