Halloween Matching

Match 3 or more identical Halloween avatars to make them explode before time runs out. If you match 4 or more identical Halloween avatars, you'll get extra time. Match 4 identical avatars in a row/column to get a bomb. Match 5 identical avatars in a row/column to get a changing avatar, which will destroy all identical avatars and will give you extra time for each avatar to explode. If you're lucky, you'll get extra time on the board.
