"You are pitted against the monster boss by helping Ben 10 fire the alien balls so that three or more of the same balls are touching, each time you score 15 points. The outcome of Ben 10's victory is in your hands, so quickly find the best ball to fire." Another way to explain this is that you are playing a game against the monster boss. You help Ben 10 by firing alien balls at the monster boss. If you can get three or more of the same balls to touch, you will score 15 points. The more points you score, the closer you will get to defeating the monster boss.
