'In '30 moves make all of the ghosts disappear. The Tombstone at the bottom of the grid will spawn a new ghost every turn. This can only be stopped when you have eliminated all ghosts in the grid at the same time. So your objective here is to disarm those Gift Traps on the sides using boosters or special gifts, and then make all the ghosts disappear.
Try and focus on the Tombstone clearing the ghosts every turn while trying to unwrap some special gifts. A horizontal striped gift or a special gift combo will destroy both Gift Traps at the same time. Even though two ghosts are more dangerous than one, at least they’ll be on different sides and separated. If you can manage to make a ghost disappear on every turn and thus stopping them from duplicating, then the Tombstone won’t prove to be that much of an issue.
