At the start of every level you will have the option to choose boosters to help you complete the level.
The booster options are:
- Bombs - a bomb is placed randomly at the start of the level.
- +3 Moves - increase the total number of moves available to complete the level by three.
- Rockets - a rocket is placed randomly at the start of the level.
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!
