The key to completing this level is to focus on clearing one of the Candy Bombs first. Once you’ve cleared one of the Candy Bombs it’ll become much easier to clear the remaining Candy Bombs because you will have a nice open space available to you to make special candies in.
With candies of 5 colors on the playing field making it not too difficult to make special candies. Make as many special candies as you can and when possible combine them to maximize their effects.
Match candies near the bottom of the playing field as often as you can. Doing this will shift the largest amount of candies and hopefully start a chain reaction or create new opportunities to make special candies.
