Boosters are essential for completing the game's levels. For most of them, blowing them up will remove multiple pieces at once and remove obstacles. You can create boosters during the game by matching 4 or more pieces. To blow up a booster, double-tap it or swap it with a neighboring piece.
You can create the following boosters:
- Rocket Cracker: created by matching 4 pieces of the same color. Blows up pieces in each of the adjacent tiles.
- Mine: created by matching 5 pieces of the same color. Has a big explosion radius!
- Rainbow Lightning: it is a special booster that can be created by accumulating explosions from other boosters. You can find it in the lower left corner of the screen. Every booster explosion charges the lightning and fills the activation bar. As soon as the bar is full, rainbow lightning will appear on the field! Swap it with a neighboring piece, and the lightning will remove all pieces of that color from the field.
