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: сreated by matching 4 pieces of the same color. Blows up pieces in each of the adjacent tiles;
- Mine: сreated by matching 5 pieces of the same color. Has a big explosion radius!
- Rainbow Lightning: Blow up boosters to charge the Rainbow Lightning. Watch the activation bar on the left side of the screen: as soon as it's filled, a Rainbow Lightning will appear on the field. Swap the lightning with any piece to remove all pieces of the same color. Note that the lightning is not susceptible to explosions.
If obstacles or items (for example, bottles) block the Rainbow Lightning, it can be activated only using a hammer. Hit the lightning with a hammer, and all the pieces of a random color will disappear from the field.
