Bees
During certain levels, your customers will ask for honey. Create honey panels by matching at least three bees, then serve it by matching normal pieces on top of the honey. Only a few customers will ask for honey. When down to your last few customers and none of them are asking for honey, ignore the bees. Only match bees if they are in the way.
Special pieces
Match four pieces to create a Blaster piece. When activated, it will shoot a beam that instantly matches all pieces in the row or column it is in. Match pieces in a square pattern to shoot a rocket that randomly creates a Blaster piece of that same type. Match five pieces to create a rainbow piece. Moving that piece on any other regular piece type to instantly match all pieces of that type. Match six pieces to create a super magnet. When moved on any other piece, it will attract pieces of that type from all over the level. They will surround the magnet and become matched immediately. While moving towards the magnet they will shift other pieces around.
