This level is easy except for the third board which makes it overall hard.
1st board: Clear the blocks normally.
2nd board: Clear the blocks normally. Save the Magic Orb even if it takes some moves!
3rd board: This board is a bad design. If you do not have a match under at least one totem you cannot bring them down. And just too often there is no possible match at the exit tile. And if there is, then there is none on the entry.
4th board: Don't care for water flow, just bring down the totem.
