You need to make quite a bit of special candies and special candy combinations to remove the large amount of blockers. Luckily with candies of four colors on the playing field you shouldn’t have too many problems making special candies, especially after you’ve cleared some of the Candy Ice Cubes.
Mainly focus on making special candies you can use to hit the Candy Ice Cubes because clearing those is the most difficult bit about this level. Vertical Striped candies and Striped + Wrapped candy combinations are great during this level.
Being able to combine the Color Bomb candy (highlighted in red, image below) with a Striped candy after you’ve cleared most of the blockers will help tremendously. Keep this in mind and make moves accordingly.
While matching candies at the bottom don’t ignore making special candies at the top of the playing field. Pause after every move and glance at the entire playing field to see whether you can make special candies.
As for the Licorice Swirls, when given the chance clear them by matching candies adjacent to them. You don’t want them to block the effects of special candies.
