It's a challenge clearing the jellies, as the jellies are surrounded by two-layer icing and are also behind the liquorice swirls, making destroying them somewhat difficult, as the former blocks the player from destroying the jellies by using cascades and the latter prevents the destruction of jellies by striped candies on the bottom of the board. Always try to chip away at the 2 layer icing.
Look for chances to clear icing. The faster you break into the jelly squares, the easier the level will be. Then, clear jelly squares. Remember, create regular matches beside the licorice swirls before blasting the jellies with striped candies.
