I'm really confused about the power ups for this game. When you complete a Magic Card, a new Power Up gets added, but unless I missed something, there's never any explanation of how it works.OK, I get that not all power ups are available on all levels.I get that when a power up IS available, matches of a specific object will fill that power up faster, and that this object may vary from level to to level. So if the freeze snowflake has a seahorse next to it, any matches with seahorses will start to refill it. I understand that part.But I still can't figure out what the power up with the Lyre/Musical note does. It's some kind of shuffle, but is it just a random shuffle? Also, is there anywhere that explains just what each of the power ups does?Thanks!
