In 30 turns make all the ghosts disappear. And if you are not lucky enough to get a match in the center of the grid, then you can forget about those gifts in there. The Tombstone in the center is blocked off by Golden Blockers and ghosts stuck in Sticky Cobwebs and Gift Traps. After five turns or so, Iron Moving Blockers will begin spawning from the top, but they can relatively help block off some of the ghosts. More Sticky Cobwebs will drop down as well, trapping random gifts.
Only the Gift Traps will prove to be somewhat of an issue, however the grid is big enough to allow for plenty of matches. Try and smash the Gift Traps when there are no more ghosts around, and try doing so with the help of multi-hitting combos or boosters.
