The uppermost isolated jelly in the top right corner is the biggest problem, as it can only be cleared only by a colour bomb or a striped + wrapped combination. The lower of the two isolated jellies can be cleared in this way, but it can also be reached using a simple striped candy.
To reach the uppermost jelly, a striped + wrapped combination must be detonated from either the topmost row or the far right column. The far right column is easiest to set up, because the special candies will not tend to fall out of place prematurely during cascades. You can use the conveyor belt to move your special candies to one of these locations.
Another approach is to manipulate the board so the two jellies in the top right corner are the same colour. A single colour bomb can then effectively eliminate both jellies, leaving only the basic board to clear.
The second most difficult area to clear is left side of the board. When bombs fall they move right, so most action naturally occurs on the right side. Watch for opportunities to clear the top and left side whenever you are not fighting bombs. Making combinations will also clear all the way across or up and down.
