At the start of the level focus on clearing Candy Ice Cubes one by one instead of hitting random ones all over the place. With each Candy Ice Cube you clear it will become increasingly easier to match candies and make special candies.
To clear the Peppermint Sticks quickly try to activate the Wrapped candies adjacent to them as soon as possible. Their double explosion will make quick work of the Peppermint Sticks.
With candies of five colors on the playing field you shouldn’t have too many problems making special candies. Still, take your time and don’t miss out on opportunities to make special candies. Consider holding on to special candies until you can combine them because of the combination’s enhanced effect.
As you clear more and more Candy Ice Cubes 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. This in turn will hopefully start a chain reaction that will create new opportunities to make special candies.
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.
