The goal is to clean the bubbles off the field. Just point the mouse to where you want the next bubble to go, and if three or more of them came together, they will detonate (the bigger the explosion - the more points you get). If some bubbles are disconnected from the rest, they will explode too (this will give you ten times more points).

Shoot down the invading UFOs with your military aircraft`s rockets in this action game. Fill the sky with UFO detritus as you shoot down the alien invaders. Watch out for return fire though as your enemy will shower you with their own rockets in return. As you cut down the invasion waves you will find that more aliens appear to confront you.
