First you have to make special candies that will clear the Marmalade in the middle column and free the trapped Striped candies. A vertical Striped candy or a Striped + Wrapped candy combination will work just fine. Once you’ve free the special candies in the middle column you can combine them to clear an nice chunk of the Jellies.
At this stage most of the Jellies in the middle columns will have been cleared and only the difficult ones will be left. With candies of five colors on the playing field you shouldn’t have too many problems making special candies. Focus on making special candies that will clear Jellies in the first and last columns. Don’t forget that you can also clear Jellies simply by matching candies on them.
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. It would be a waste to miss out on a chance to make a special candy only because you didn’t take your time.
Throughout the level pay attention to Candy Bombs and defuse them when given the chance. This shouldn’t be a problem because of their 14-move timer.
