Stack Pile Up
Stack Pile Up is a fun arcade game where you build a tower of aliens by stacking them on top of each other. To start, click "Play" and the arrow. At the top of the playing field, an alien flies from one side to the other. Wait for it to line up with the platform below and click to reset. If you have correctly calculated that the monster will fall clearly in the center of the pedestal. Then drop your brothers on it to build a stable pyramid. Please note that if the cube falls on the edge, the structure will turn out to be unstable and collapse. Manage to build the highest possible tower.
