Boosters, also known as power-ups, are very special and important elements you may and should use when you feel stuck or if a level becomes too hard.
You have several types of boosters:
1. Bomb- This will help you explode a group of regular bubbles standing in your way.
2. Fireball- This will clear you a path if you fire it in a specific direction, making all bubbles in the way drop.
**Tip: You should know, that once you choose to use one of these boosters, there is no changing your mind, and you will have to use it. We advise you to use it wisely!
