First clear the Licorice Lock at the center of the playing field. Clearing it will increase the open space in which you can make special candies by quite a bit, making it easier to make them.
Next you have to focus on two things at the same time. Firstly, you have to focus on making special candies and use them to clear blockers. With candies of five colors on the playing field you shouldn’t have too many problems making special candies. It’s worth holding on to special candies until you can combine them because of the combination’s enhanced effect.
At the same time, you have to focus on clearing Licorice Locks by matching the candies they’re trapping. You don’t want to solely rely on special candies and chain reactions to clear them for you. The quicker you clear them the easier the level will become.
Match candies near the bottom of the playing field (or as low as possible) as often as you can. Doing this will shift the largest amount of candies and hopefully start a chain reaction that will create new opportunities to make special candies.
