AstroPop is an arcade puzzle game. The objective is to guide a space ship that stacks and shoots bricks. As the amount of bricks on top of the screen increases, you need to pop a target number of bricks with matching colors before the rows reach the bottom of the screen. By linking four bricks or more, you create chain reactions. To spice up the gameplay, there are special power-ups such as radial bombs, freeze bombs, column nukes, and difficult obstacles such as toxic, steel, and stone bricks.

Each of the four playable characters has a "Supa" weapon that destroys all bricks on the screen once charged. There are two play modes: Classic, with weapon upgrades and 32 levels per character and Survival, in which you need to stay alive as long as possible.
