Wrapped Candy can be produced by creating two 3-match combination of the same color in just a single move.Another way to see this, is that Wrapped Candy is formed when you make a match in a 'T' or 'L' shape.
When it is activated, it explodes and all the immediate surrounding candies are destroyed. Then, it will drop and expode again clearing another 8 candies (3x3 board space).
Wrapped Candies work great on boards with Licorice Swirls or Multilayered Icing.
They can be combined with other special candies for bigger and better effects. These effects are shown in the video below:
