In Zumball, you will have to shoot a ball in various situations to help the frog defend. In each level, you have to shoot a ball to blast all of the marbles and collect them. However, you can only shoot a ball that appears on the screen, and there is also a chance of being blocked by a ball or by a stone. Once you blast a marble, the next ball will appear on the screen. The marbles are in different colors, and if you collect the ball that appears next, then you will be able to blast it and add it to your collection. However, if you shoot too many balls in the same level, then you will get blocked and the game will be over. The game ends when you get three stars in each level.

In Zumball, there are several different classes of marbles. You can shoot with or without power-ups. However, if you shoot with a power-up, then it is possible to blast several marbles in one shot.
