You can create three boosters in the game: Line Choco, Cross Choco and the Choco Bomb. You can make a Line Choco by tapping a matching set of 4 or more candies of the same color. The more candies are combined, the bigger the booster! 

You can enhance boosters even further by combining them! Two Line Chocos will create a Cross Choco the same size as the largest. Similarly, combining two Cross Chocos will create a Bomb Choco. Using these boosters is a great way to blast a large amount of candies at once while saving moves on a level!
