You have lots of jellies to clear, and there are 2 islands and 1 big peninsula. This level is hard due to the sheer amount of jelly.
The jellies on the islands are especially very hard to reach, as they are only 2 by 2 wide, meaning it's impossible to use regular matches to destroy the jellies. Moreover, no new candies will drop down to the islands unless the player has destroyed the icing over the teleporters.
The player is provided with three color bombs, though it probably won't clear all jellies on the islands, unless they are combined with another special candy.
Six colors minimizes the creation of special candies.
Doing the wrapped-striped combo is useful for clearing the middle area of the board, and if you managed to make it on the bottom of the board, it is useful for the islands too. The best way to get the single jellies in the hard-to-reach areas is to make a color bomb + striped candy combo to have an easier time clearing them. Use your moves wisely as all spaces include jelly.
