Pop-A-Tronic follows the basic rules of most brick-busting, strategy games. In this instance, your "bricks" are a series of multi-colored bubbles. Match three or more likeminded bubbles and you immediately remove them from the screen. Trouble is, the screen seems to fill up as fast as you clean it up. Engage in one of four dynamic play modes, including marathon (ongoing screens filled with endless bubbles), puzzle mode (requires careful planning before you start), lockout mode (the walls of your screen shrink as you play), and self-destruction mode (a clock ticks as you try to remove the bubbles from the screen as fast as you can).
