At the start of every level you will get the option to choose one, two, or three boosters to help you complete the level.
The booster options are as follows:
- Bombs - one of these will appear randomly somewhere in the level at the start
- +3 Moves - this increases the total number of moves you have for completing the level by three
- Shuffler - use this to shuffle the position of the balloons at any time
These boosters can be purchased at the start of a level with silver coins. Just tap the boosters that you want to use on the pre-level screen so that a green checkmark appears next to it, and the booster will then be available for that level!
