Level 342 is the seventh level in Pearly White Plains and the one hundred forty-seventh jelly level. To pass this level, you must clear 26 jelly squares and score at least 40,000 points in 25 moves or fewer. If you have extra moves left in this level, Sugar Crush will activate jelly fish to eat candies and score you additional points.
This level is entirely based on luck, therefore has no actual feasible difficulty rating. Getting a colour bomb and a jelly fish is pretty much a guaranteed win, whereas one can also be very unlucky with their fish and therefore is a guaranteed loss.
If a colour bomb can be created, try to combine it with a jelly fish. This combo should summon a lot of jelly fish to help eating the bottom jellies.
Otherwise, simply get rid of the six jellies at the top of the level before using any of the jelly fish, as the only way to get rid of the jellies under the meringues at the bottom of the level is to use most of the jelly fish to destroy the jelly underneath them.
