First clear the Licorice Lock in the middle of the playing field. Clearing it will not only make it easier to spread the Jam, it will also allow you to create special candies more easily because the Licorice Lock isn’t in the way any longer. Once you’ve cleared the Licorice Lock don’t worry about spreading the Jam because it will spread automatically in 99% of the cases.
Next you have to focus on clearing some of the Candy Ice Cubes one by one because this will allow more candies on the playing field. With candies of five colors on the playing field you will want to have as many candies on the playing field as possible because not only does this make it easier to create special candies, it will also increase the chances of chain reactions happening.
To clear the Candy Ice Cubes (especially the ones in the left and right corners) you will have to combine special candies often. Combining Wrapped candies with Striped candies a few times might get you close to completing the level. but to clear the Candy Ice Cubes in the corners I suggest you try to combine Coloring or Color Bomb candies with Striped or Wrapped candies.
Match candies near the bottom of the playing field as often as you can. Doing this will shift the largest amount of candies, hopefully start a chain reaction and create new opportunities to make special candies. While matching candies at the bottom it can be easy to ignore making special candies at the top of the playing field. So pause after every move and glance at the entire playing field to see whether you can make special candies.
