At the start of a new level you can see how many balls you need to dunk to proceed to the next level. You get 10 balls per level. Dunk all 10 for a bonus! The more stars a dunk has, the more points it scores and the harder it is to execute! When you catch the ball, try to be high in the air: if you are to low beneath the basket, you will fall. When dunking, make sure the dunk-indicator is as close to the middle as possible.
