The Kaboom! game sees you in the role of defender against the mad bomber, who zooms back and forth at the top of the screen dropping bombs. Your goal is to catch these bombs by placing them in buckets of water. Each bomb caught earns you points, but missing one will mean you'll hear the dreaded "Kaboom!" sound effect. As levels progress, the mad bomber gets faster and drops more bombs, making it harder for you to keep up.
The gameplay is simple: move your character left or right to position yourself to catch the incoming bombs. You start with three buckets of water, but each bomb missed will see one bucket disappear. The game ends when all of your buckets are gone, so think carefully before making a move.
