Booster Boxes are pre-game boosters that will apply a beneficial effect to the game-board. All Boosters are randomly selected with each power-up having equal weight:

Dynamite: 20%

Waterfall: 20%

Sure Shot: 20%

Force Flood: 20%

Air Strike: 20%

However, please note that some levels specifically exclude the use of Booster Boxes or specific Booster Box power-ups that do not work with the level design.

Booster Boxes can be acquired with Gold in the Store, occasionally from Daily Doors, with Golden Keys, and as event rewards.
